Who Controls the Global Grain Trade? The Evidence Behind the 80% Claim

There is no reliable evidence that five companies control half of all the food in the world. That widely circulated claim confuses international trading in a limited range of agricultural commodities with the entire global food supply. It treats the companies that buy, store, process and ship crops as though they own or control everything people eat.

But there is a serious question underneath the exaggeration. Five enormous businesses — Cargill, Archer Daniels Midland (ADM), Bunge, Louis Dreyfus Company and COFCO — occupy influential positions in global grain and oilseed supply chains. Some own the infrastructure farmers need to reach markets. Some finance and transport shipments across continents. Several conduct significant financial trading alongside their physical commodity businesses.

How concentrated is that trade, and how much pricing power does concentration create? Published answers range from an estimated 70–80% share for an expanded group of major traders to 27–32% for the four largest companies in a different, shipment-based study. Those figures are not measuring the same thing. Neither is a verified answer to who controls the world’s food.

A viral video by It’s Complicated further claims that a United Nations investigation found major grain traders hoarding supplies until prices peaked during the Ukraine war. The underlying reports do not establish that specific sequence of conduct.

This briefing traces the statistics and allegations to their sources, examines what recent corporate consolidation actually changed, and identifies the missing evidence that would allow the public to judge the industry’s influence more accurately.

Executive assessment: the key findings

The strongest conclusion is not that the companies are harmless or that they collectively run the world’s food system. It is that different forms of economic power have been compressed into one dramatic, poorly defined percentage.

The first problem: grain trading is not the same as the world’s food supply

Consider the size of the actual market. In its October 2026 Cereal Supply and Demand Brief, the UN Food and Agriculture Organization (FAO) forecast approximately 2.979 billion tonnes of world cereal production in 2026 and 505.8 million tonnes of international cereal trade in the 2026/27 marketing season.

The production and trade figures use different reporting periods, so they should not be converted into a precise share of the same crop year. They do, however, establish an essential distinction: most cereals produced worldwide are not represented by the cross-border cereal trade in any single marketing season.

Much of that grain is consumed or processed domestically. Some is used to feed animals or manufacture fuel and industrial products. International traders also handle soybeans and other oilseeds, which are not cereals. Meanwhile, vast quantities of vegetables, fruit, dairy, meat, fish and locally distributed foods sit outside the grain-trading figures entirely.

A company may purchase wheat from a farmer, store it at an elevator, arrange a ship, hedge the price on a futures exchange and deliver it to a mill. That creates commercial leverage at several stages. It does not mean the company grew the wheat, owns the bread made from it or determines every price between the farm and the supermarket.

The phrase controls the world’s food conceals at least four different questions: Who owns the crop? Who handles or trades it? Who controls the infrastructure needed to move it? And who has enough bargaining or market power to influence prices? Each requires different evidence.

Who are the five companies?

For decades, global commodity trading was described through the acronym ABCD: Archer Daniels Midland, Bunge, Cargill and Louis Dreyfus. China’s COFCO has since become a major international competitor, while Bunge’s acquisition of Viterra changed the industry’s corporate structure in 2025.

Ownership and reporting can be checked through ADM’s investor disclosures, Bunge’s merger announcement, Cargill’s annual report archive, LDC’s 2025 integrated report and COFCO’s corporate description.

Two qualifications matter. First, privately owned does not mean exempt from law or entirely invisible. Cargill and LDC publish financial information, and ADM and Bunge face the disclosure obligations of listed companies. Second, corporate financial reports do not reveal the entire physical trading book: the location and ownership of every stockpile, the final counterparties behind every shipment and the terms of every commodity contract are not generally public.

There are also important companies outside the five: CHS, Zen-Noh, Olam, GrainCorp, regional cooperatives and major Russian traders, among others. The leading names can change by grain, country and type of transaction. There is no fixed roster that dominates every agricultural market.

Where did the 70–80% claim come from?

The higher figure has an identifiable research trail. A 2024 study commissioned for the European Parliament’s Agriculture and Rural Development Committee estimated that the traditional ABCD firms handled approximately 50–60% of worldwide trade in selected cereals, oilseeds and protein crops. Its broader analysis included additional major firms such as COFCO International and Viterra.

The ETC Group’s February 2026 report Grain Traders, Greed and Oligopoly Power cites the European work in support of an estimated 70–80% share attributed to five leading corporate groupings after Bunge and Viterra combined. ETC Group is a research and advocacy organization concerned with corporate concentration in food systems; its report is relevant evidence about the argument, not an independent audit of every underlying shipment.

There is a subtle chronological issue here. Viterra and Bunge were separate businesses during the period informing the older company-volume estimates. They became part of one corporate group in July 2025. Recasting the earlier figures as the current share of five merged companies does not update the underlying quantities.

What the higher estimate measures — and what it does not

The European Parliament-commissioned research drew on company-reported and estimated volumes. Its illustrative comparison includes commodities handled or processed, not merely cargoes exported by the named firm. Some inputs were modeled; one Bunge volume came from a different reporting year because the company’s disclosures had changed.

That poses two important problems:

1. The numerator may include unlike activities. A reported quantity handled across trading and processing operations is not necessarily equivalent to one independently identified international shipment. A commodity may pass through more than one company’s operations.
2. The denominator has to match. Total corporate volumes cannot simply be compared with a narrower estimate of cross-border crop trade without checking commodity coverage, time period, geographic scope and double-counting.

The result is useful as an indicative picture of large-company scale. It should not be presented as an audited market share of all grains, much less of all food. Nor does a high concentration estimate, by itself, establish an illegal agreement to fix prices.

This is not the first time a large percentage has spread without retaining its original definition. The older 70–90% narrative appears across decades of studies and commentary, sometimes using U.S. exports, sometimes particular commodities, and sometimes revenue-based estimates for preselected firms. The 2025 shipment study discussed below reviews that history, including how an influential 73% figure was derived from a limited group of companies rather than a complete measurement of worldwide trade.

A 2025 study found something very different: 27–32%

In May 2025, William W. Wilson, David W. Bullock and Isaac Dubovoy of North Dakota State University published Dynamic Changes in the Structure and Concentration of the International Grain and Oilseed Trading Industry in Applied Economic Perspectives and Policy.

Instead of relying primarily on company-level turnover and handling estimates, the authors analyzed international vessel-shipment records from 2020 through 2023. They assembled 62,271 free-on-board (FOB) records and 48,098 cost-and-freight (CNF) records, and reported that their dataset covered approximately 80% of relevant world grain and oilseed trade.

FOB means free on board; CNF means cost and freight. They are different shipping-contract arrangements, and the related records can identify different trading roles. The percentages below should not be treated as two estimates for exactly the same group of companies.

Their Table 2 reports the combined shares of the four largest traders in each defined market:

Source: Wilson, Bullock and Dubovoy (2025), Table 2. CR4, the four-firm concentration ratio, measures the combined share of the four largest participants within each specified dataset. It is not a universal share held by one unchanging group of companies.

The largest four firms in the worldwide FOB records were Cargill, COFCO, ADM and LDC. For CNF records, the group was COFCO, Bunge, ADM and Cargill. The study also identified a larger cluster of seven leading firms — including Viterra and CHS — accounting for 45% of worldwide FOB shipments in its dataset.

Those results challenge the idea that four historical ABCD companies command an invariant 70–90% share of international shipments. But the 27% and 32% findings do not tell us the combined 2026 share of Cargill, ADM, Bunge/Viterra, LDC and COFCO. They count four leaders rather than five groupings, they cover a different set of activities, and they predate the completed merger.

Three reasons not to treat the lower figure as definitive

Some traders were unidentified. The authors state that 21% of FOB records and 22% of CNF records had unspecified trading parties. The records remained in the total market denominator; for the four-firm ratio, the study effectively assumed the unidentified trade did not belong to a leading firm. If some of those cargoes did belong to major firms, reported concentration could be lower than the true value. The quoted percentages refer to shipment records, not necessarily identical shares of cargo tonnage.

Shipments are only one layer of the business. Vessel data say much more about observable international cargo movements than about who owns inland elevators, what farmers are offered for their crops, which companies finance deliveries, or who controls terminal capacity during a disruption. Those forms of economic power require other measurements.

The observations are historical. The researchers studied 2020–2023, before the Bunge–Viterra merger. The results should not be relabeled as the state of the industry in October 2026.

The paper’s own numbers require caution

Our comparison of the paper’s Table 2 and conclusion found internal inconsistencies. Table 2 gives 32% FOB and 27% CNF, but the conclusion lists those percentages in the opposite order. Table 2 reports a worldwide FOB Herfindahl–Hirschman Index (HHI) of 492, while the conclusion states 885. The CNF HHI is 442 in both locations.

The figures cannot all be correct as printed. This briefing uses the clearly labeled, market-specific values in Table 2, without claiming to have independently recalculated the underlying data. The authors say the shipment dataset is available on request, not openly released as a reproducible public database.

There is also a material funding disclosure: the authors report support from North Dakota State University’s Center of Trading and Risk and an unnamed major international grain-trading company. They separately declare no conflicts of interest. Industry funding does not disprove their analysis, but an undisclosed commercial funder and unreleased transaction data increase the importance of examining assumptions rather than treating peer review as the last word.

The defensible conclusion is therefore narrower than either extreme: the older high estimates are not directly comparable with the newer shipment figures, and neither source provides a fully independently verified, post-merger measure of global market power.

Market share is not the same as market power

Consider a farmer deciding where to deliver a harvest. The important question may not be how many corporations move grain worldwide. It may be how many economically reachable, independent buyers can accept that farmer’s crop at the necessary time and price.

A shipping market can contain many traders while an individual growing region has very few nearby elevators. A global trader can face international competition yet own an essential local terminal. Conversely, a large company can possess extensive infrastructure without being able to dictate international benchmark prices.

The BRICS Competition Law and Policy Centre’s From Fields to Futures report emphasizes vertical integration, commodity finance and digital infrastructure. That is an analysis of possible competition risks and a basis for policy proposals, not an adjudicated finding that the five companies operate an illegal cartel.

The Bunge–Viterra merger shows why local competition matters

Canada’s review of the Bunge–Viterra transaction offers something the worldwide percentages cannot: a documented assessment of a particular market and its likely economic consequences.

In January 2025, the Canadian government approved the acquisition subject to enforceable conditions. These included divesting six western Canadian grain elevators, protecting certain purchasers of canola oil and limiting Bunge’s influence over G3, in which it held a minority interest.

The underlying Canada Gazette order explains the competitive concern. The Competition Commissioner warned that combining Bunge’s processing operations with nearby Viterra and G3 elevators could leave canola farmers around Altona, Manitoba, and Nipawin, Saskatchewan, with fewer viable buyers. The commissioner’s analysis estimated C$15 million–C$19 million in potential annual lost farm revenue in those two regions if the transaction proceeded without effective remedies.

That is a regulator’s prospective estimate of unremedied harm, not evidence that farmers subsequently lost C$15–19 million.

The merger closed on July 2, 2025. Bunge reported selling five elevators to local operators in November. On January 23, 2026, it announced the sale of the sixth, at Valparaiso, Saskatchewan, to Cargill, following government approval.

Selling a divested facility to another large trader does not itself prove the remedy failed, nor does the approval establish that competition concerns disappeared. The publicly documented case shows the problem regulators were trying to solve: a farmer’s available buyers, a processor’s alternatives and a route to market can matter more than an industry-wide concentration ratio.

Did a UN investigation prove grain traders hoarded supplies during the Ukraine war?

No. The reports commonly cited for this allegation do not establish that the five traders deliberately withheld grain until prices peaked and then sold it for maximum profit.

The relevant argument appeared in IPES-Food’s May 2022 report Another Perfect Storm?, written in the early months of Russia’s full-scale invasion of Ukraine. The report described opaque private grain stocks and said large traders had a clear incentive to hold inventory until prices were perceived to have peaked. Its executive summary also characterized grain hoarding as a contributor to the crisis.

The report is not merely a hypothetical discussion of risk. It takes a critical position on the food-trading system. But the company-specific passage does not present dated inventory records, transactions, delayed shipments or sales prices proving that each named trader followed the precise hoarding-and-sale sequence described in the video.

The UNCTAD Trade and Development Report 2022 cited that IPES-Food assessment. The citation did not transform the original argument into a transaction-level UN finding of coordinated wrongdoing.

There is a substantial difference between these three statements:

• A trader with inventory could benefit from withholding supply in certain market conditions.
• Limited stock transparency creates a plausible risk that traders may amplify shortages or volatility.
• Named companies were proved to have coordinated withholding and sales at the price peak.

The first two are legitimate research and regulatory concerns. The third requires evidence that the cited reports do not supply.

Failure to prove this particular allegation does not prove that no trader has ever withheld grain strategically. It establishes the narrower, essential fact-check result: this widely repeated accusation has become more definite than the documentary evidence supporting it.

What UNCTAD actually said about crisis profits

UNCTAD’s Trade and Development Report 2023, Chapter III examined unusually strong profits at major food traders, market volatility, derivatives and weaknesses in financial oversight. It found that financial profits were closely associated with turbulent commodity markets and argued that speculative activities merited greater scrutiny.

Crucially, the report did not establish speculation as the cause of the food-price spike. It expressly cautioned that correlation was not causation and identified geopolitical shocks, trade measures, climate conditions, supply and demand, and downstream food-sector costs as relevant influences.

The correct interpretation is not that the companies made no unusual profits. Some did. It is that earning profits during a crisis, benefiting from volatility and causing that volatility are three different claims.

How much of grain trading has become financial trading?

This part of the industry deserves attention without resorting to the claim that every futures contract is evidence of manipulation.

A company buying grain today for delivery months later faces price, currency, freight and financing risks. Futures, options and other derivatives can be used to manage those exposures. They can also create financial positions not directly tied to a specific physical shipment. Which activity is occurring, and at what scale, cannot be inferred from the word derivatives alone.

In its Trade and Development Report 2025, Chapter III, UNCTAD argued that commodity traders have increasingly become financial intermediaries. It cited estimates of financial-intermediation income reaching roughly three-quarters of revenue for major firms. Its Figure III.6 presents mark-to-market valuations of derivatives income as a share of total revenue, averaged over 2018–2024, for selected companies: 51% for Cargill, 71% for ADM and 72% for Bunge, among others.

Those are accounting-based ratios, not direct measurements of net profits from illegal speculation. The figure does not present equivalent ratios for COFCO and LDC. Further, agricultural forward sales and hedging contracts can be accounted for as derivatives even when they arise from physical commercial activity: Bunge’s 2025 annual filing explicitly describes that treatment under U.S. accounting rules.

UNCTAD’s concern about financialization is substantive. But determining whether those accounting figures represent speculative gains, commercial hedges, gross revenue classifications or offsetting losses requires company-specific reconciliation. No one should translate a derivatives revenue ratio into a claim that three-quarters of grocery prices or corporate net profits come from market manipulation.

The industry’s visibility problem is therefore specific, not absolute. The U.S. CFTC publishes Commitments of Traders data, but public tables aggregate many positions rather than exposing every company book. The European Union has cereal and oilseed stock-notification requirements, but those are not a public inventory ledger identifying every private owner and trading strategy worldwide.

Can grain traders raise the price of groceries?

They can affect purchasing, freight, processing or wholesale conditions in specific markets. That is not the same as controlling the final shelf price.

A typical grain-based product moves through several economic stages:

Farmgate price → crop elevator or trader → storage and transport → mill or processor → manufacturing and packaging → distribution → retailer.

Some stages belong to one vertically integrated company. Others are independent. Price changes can come from crop failures, export restrictions, fuel costs, currency swings, labor, contracts, processing capacity and retail pricing decisions, as well as traders’ margins or market power.

The USDA’s revised Food Dollar research estimated that farms received 18.5 cents of every dollar spent on domestically produced food purchased for consumption at home in 2024. The remaining 81.5 cents represented post-farm marketing activity, including processing and retailing. It was not an 81.5-cent profit margin for grain traders.

For a narrower example, USDA’s retail flour price-spread data report the following for one pound of all-purpose white flour in 2024:

Here is a transparent illustration, not a forecast. If the farm value of the wheat in that pound of flour rose 50%, the farm component would increase by 5.25 cents. With every other cost and margin held constant and the entire increase passed through, the retail price would rise from 56.5 to 61.75 cents — approximately 9.3%, not 50%.

Actual price transmission can be slower or larger depending on contracts, margins, product formulation and other input costs. This calculation does not measure the influence of any particular trader. It establishes why a percentage change in wheat prices should not be reported as the same percentage change in bread or grocery prices.

Exposure is also unequal. A country dependent on imported grain and a limited number of shipping routes may be vulnerable to a maritime disruption. A farmer with only two reachable buyers may be vulnerable to lower bids. A diversified importer, a cooperative with alternative rail access or a region with abundant local production faces a different set of conditions.

For related consumer and freight economics, see sherafy.com‘s reporting on supply-shortage claims and diesel costs and surveillance pricing in grocery stores. These concern different stages of the supply chain and should not be confused with grain-trader market concentration.

What is being investigated now?

Two developments have made older concentration estimates less useful as descriptions of the current industry.

Bunge and Viterra completed their merger in 2025. A proper current share calculation would need to incorporate actual post-merger flows, changing customers, competing exporters and any divested assets. Simply adding historical company figures cannot show the competitive outcome.

In July 2026, the BRICS Competition Law and Policy Centre announced a joint inquiry into global grain trading. The initiative, co-chaired by competition authorities from Brazil and Egypt, examines market structure, financing, transparency and digital platforms. Organizers anticipated presenting findings in 2027. An inquiry is not a determination of unlawful conduct.

The FAO’s October 2026 cereal briefing separately reports lower projected international trade, partly because of Black Sea shipping constraints. That is a reminder that even where company ownership does not change, war, transport bottlenecks and export policy can materially affect supply.

The records needed to settle the question

A genuinely decisive inquiry would need to connect current, identified shipments with facility ownership and throughput, regional farm bids and available buyers, inventories and their beneficial owners, and company-specific derivatives exposures and the physical contracts they hedge. Publicly available sources currently provide fragments of that picture rather than a comprehensive, replicable global dataset.

Frequently asked questions

Do five companies own the world’s food supply?

No. The five firms have significant roles in trading, storage, transport and processing, but there is no reliable evidence that they own or control half of all food produced or eaten worldwide. International grain shipments represent a narrower activity than the food system as a whole.

What are the ABCD grain trading companies?

Archer Daniels Midland, Bunge, Cargill and Louis Dreyfus Company. The shorthand is historically important but increasingly incomplete because COFCO and other competitors are active, and Bunge absorbed Viterra in 2025.

Is Cargill privately owned, and is COFCO owned by China?

Yes. Cargill is a privately held, family-owned company. COFCO identifies itself as a Chinese central state-owned enterprise. The companies’ ownership models differ, and their ownership does not itself establish collusion.

Do the five companies control 80% of grain trading?

A widely cited study-derived estimate approaches that range for selected crop-trading and handling activities, while a 2025 paper found materially smaller shares for the four largest firms in historical shipment records. Both measures have limitations. This investigation does not establish a single independently verified, post-merger five-company percentage for October 2026.

Did a UN investigation find that grain companies deliberately hoarded grain during the Ukraine war?

The cited IPES-Food and UNCTAD documents discuss stockholding incentives, limited transparency, volatility and profits. They do not establish the precise claim that the five named companies withheld grain together and sold at the market peak.

Do high grain-trading profits mean the firms manipulated food prices?

No. Profit, volatility, legitimate hedging and unlawful price manipulation are different concepts. High profits can justify closer scrutiny, but assigning responsibility for a price shock requires evidence about the company’s conduct and the other forces affecting the market.

Can any one company set the price of wheat or bread?

A company may have leverage in a particular procurement, storage, shipping or processing market. The evidence here does not show one company setting worldwide wheat prices or retail bread prices. Those markets involve many participants and cost components.

Bottom line

The claim that five companies control half the world’s food is not supported by a meaningful, verifiable definition of global food control. But the simpler dismissal — that a low international shipment share proves there is no market-power problem — is just as unsatisfactory.

The higher estimate relies on imperfect company-volume comparisons. The lower estimate is built from detailed shipping records but contains unidentified counterparties, unreleased underlying data, an industry-funding disclosure and internal numerical inconsistencies. Neither is a contemporary, comprehensive inventory of the power these businesses may exercise over individual trade corridors, terminals, crop markets or financing relationships.

Canada’s Bunge–Viterra review demonstrates that these issues can have quantifiable local stakes: regulators anticipated millions of dollars in potential annual farmer-revenue losses without remedies. The UN reports establish concerns about opacity, speculation and extraordinary profits, not the specific hoarding conspiracy asserted in the viral video.

The important question is no longer which alarming percentage sounds most convincing. It is who controls the infrastructure and options available to farmers and food importers, what that control does to prices, and which records are still needed to measure it.
