The Justice Department has widened its antitrust investigation into soaring beef prices beyond the meatpacking giants and into the grocery aisle, demanding six years of pricing and profit data from eight of the nation's largest retailers.
Attorney General Todd Blanche's DOJ sent letters in July to Walmart, Amazon, Costco, Kroger, Publix, Albertsons, Aldi, and Ahold Delhaize USA, the parent company of Food Lion, Stop & Shop, and Giant, seeking detailed information on beef purchasing strategies, retail prices, costs, profit margins, and wholesale-to-retail price trends. None of the retailers has been accused of wrongdoing. But the scope of the request signals that federal investigators believe the problem may run deeper than the processing plants where the probe began.
The expansion follows a broader investigation the DOJ announced in May into potential antitrust violations across U.S. cattle and beef markets. That earlier phase targeted the so-called Big Four meatpackers, JBS, Cargill, Tyson Foods, and National Beef, which together control more than 85 percent of U.S. beef processing. Investigators have already reviewed more than three million documents and interviewed industry participants, the Daily Mail reported.
The numbers explain the urgency. Ground beef averaged $7.116 per pound in July, according to the Bureau of Labor Statistics. That figure was up roughly 10 percent year-over-year, the Washington Examiner noted, putting a staple protein further out of reach for working families already squeezed by years of elevated food costs.
Steak prices have climbed even more steeply. Ground beef averaged $6.32 per pound as recently as last September, and beef steaks hit $12.62 per pound around the same period, with prices continuing to trend higher since, Newsmax reported earlier this year when the DOJ first opened its criminal inquiry into the meatpackers.
Agriculture Secretary Brooke Rollins has pointed to a fundamental supply problem: the U.S. cattle herd stood at roughly 86.2 million head at the start of the year, the lowest level since the 1950s. Drought, disease, and years of policy neglect have all contributed to the shrinking herd.
Rollins put the blame squarely on the prior administration.
"We are suffering from the last administration's literal war on cattle."
Treasury Secretary Scott Bessent added another dimension, telling reporters that mass illegal immigration had helped reintroduce a livestock disease that the U.S. had previously eradicated in North America.
Blanche has framed the investigation in blunt terms. In a statement accompanying the probe's expansion, the attorney general cited plant closures and market concentration as red flags.
"Multiple plant closures across the country, the current market structure, and high concentration in the industry indicate anticompetitive activity."
Deputy Assistant Attorney General Nicole Sarrine spelled out who gets hurt when the market is rigged, and it is not the corporate boardrooms.
"The victims of such anticompetitive coordination can include consumers to whom they sell their products, as well as small and independent businesses that provide necessary inputs, such as, in the cattle industry, ranchers and cattlemen."
That framing matters. If the Big Four processors control 85 percent of beef processing, ranchers have few places to sell their cattle. And if the eight largest grocery chains dominate the retail end, consumers have few places to buy their beef. The DOJ appears to be examining whether concentration at both ends of the supply chain has created a pricing squeeze that enriches the middlemen while punishing producers and shoppers alike.
Blanche has also turned to an unusual tool: money. The attorney general publicly urged industry insiders to come forward, dangling substantial financial rewards for anyone whose information leads to a major criminal penalty.
"If the information you provide helps us secure a criminal penalty in excess of $1 million, you can be entitled to recover and receive 15 percent to 30 percent of the money that we recover."
That is not a token gesture. A $100 million criminal fine, not unheard of in major antitrust cases, would mean a whistleblower payout of $15 million to $30 million. The DOJ is betting that someone inside the supply chain knows where the bodies are buried and will talk if the price is right.
The New York Post reported that the DOJ posted on social media that "beef prices are a critical concern to Americans, and a priority for this Justice Department", a public signal that the administration views this as a kitchen-table issue, not an abstract regulatory exercise.
The antitrust probe is one piece of a broader strategy. President Trump has repeatedly targeted the beef industry over high prices, calling the meatpacking sector a "nasty monopoly." His administration has moved on several fronts simultaneously.
On the supply side, Trump proposed giving farmers and ranchers more opportunities to process their own meat, a direct challenge to the Big Four's stranglehold on processing capacity. The administration also moved to increase foreign beef imports, proposing a temporary 90-day tariff-free window for up to 300,000 metric tons of imported beef to boost supply and push prices down.
That import proposal drew pushback from some cattle producers and Republican lawmakers who worried it would undercut domestic ranchers. The tension is real: cheaper imports help consumers at the checkout counter but could depress prices paid to the very ranchers the administration says it wants to protect.
On the enforcement side, the DOJ has already notched a related win. The Trump administration settled an antitrust case against Agri Stats, a meatpacking data-sharing company accused of helping inflate chicken, pork, and turkey prices by restricting buyer access to industry data. Under the settlement, Agri Stats must share most of its collected data with U.S. buyers, a move designed to increase market transparency and level the playing field for grocery chains and restaurants, Breitbart reported.
Blanche tied that case to the same theme driving the beef probe.
"A stable and affordable food supply is critical to our country's well-being. This Department of Justice is laser-focused on making everyday life affordable for all Americans."
The DOJ has not accused any of the eight grocery retailers of breaking the law. The letters are information requests, not indictments. But the sheer breadth of the demand, six years of data from eight chains that collectively sell a huge share of the beef Americans bring home, suggests investigators are building a comprehensive picture of how prices move from the feedlot to the meat case.
The beef investigation is also part of a wider DOJ effort examining anticompetitive behavior across the food supply chain, including probes into egg, fertilizer, and crop seed markets. The pattern is consistent: the administration is using federal antitrust authority to go after industries where a handful of dominant players may be profiting at the expense of consumers and smaller competitors.
Several questions remain unanswered. None of the eight retailers has publicly commented on the DOJ letters. None of the Big Four meatpackers has responded publicly to the investigation. And it remains unclear whether the tariff-free import proposal has been enacted or is still pending.
What is clear is the scale of the problem. When four companies process 85 percent of the nation's beef and the cattle herd sits at its smallest size in seven decades, the market is not functioning the way it should. Families paying $7 a pound for ground beef deserve to know whether that price reflects genuine supply and demand, or something less honest.
The Trump administration is asking the right question. Now the grocery giants have to answer it.
