President Donald Trump declared an economic victory of sorts on Monday, writing on Truth Social that “one of the biggest, best, and smartest Retailers in America, Walmart, will be lowering prices, by a lot, at my Administration’s request to celebrate our great Country’s 250th birthday.” If this characterization is accurate, Trump just happened to stumble into the realization that the president can get businesses to lower their prices simply by asking nicely. Reality, however, is far more complicated.

In fairness, Trump had an understandable motivation for broadcasting the news. Affordability remains a top issue for voters, and the president wants to save his party from a midterm drubbing that would derail his agenda in the second half of his term. Only a poor politician would ignore such an obvious political incentive, and Trump is not a poor politician. Any time Trump can connect his administration’s efforts to lower prices, he will take the chance to do so.

Trump spelled out this partisan motive in no uncertain terms. “My Administration is lowering prices that Joe Biden incompetently raised with the worst inflation crisis in history, a total disaster along with the Southern Border, the botched withdrawal from Afghanistan, and many other failures,” he announced. “Just as I promised, Oil Prices are plummeting FAST, and Gas Prices at the pump are dropping too, just like egg and Prescription Drug prices which I am bringing down by historic levels.” One can hear the implied insertion: “Vote Republican in November.”

But while Trump’s motive is understandable, his economic analysis leaves much to be desired. Trump claimed Walmart was “lowering prices … at my Administration’s request.” This claim suggests that government officials can get businesses to lower their prices merely by telling businesses to lower prices, an economic notion worthy of Democrats like Elizabeth Warren or Bernie Sanders.

For such a notion to work, the businesses in question would have to be generating enormous profit margins on the goods in question, allowing them to meaningfully lower their prices and still turn a profit. However, market forces already eliminate such profit margins in competitive markets like general retail. If one retailer tried to set such high prices, another retailer down the street would charge a lower price and take a greater market share. The first retailer would be forced to lure customers back by lowering its prices. This process would continue until both retailers were selling their goods at cost, or nearly so. Both physical retailers would also have to compete against online retailers, whose services are accessible to just about anyone anywhere.

In such circumstances, a politician’s demand for a business to lower its prices would be met with the likely reply, “We’d love to, but then we would be losing money.”

This analysis may raise a question among the more inquisitive readers. If businesses cannot simply lower prices on demand, then what should we make of President Trump’s announcement that Walmart is lowering prices?

For context, it may help to reference Walmart’s own announcement. “This summer, Walmart and Sam’s Club are helping customers and members save more with thousands of lower prices through Walmart’s signature Rollbacks and Sam’s Club offers across stores and clubs nationwide,” the corporation announced. These rollbacks included real savings such as the following:

• “1 lb. 73% Ground Beef Roll, Fresh ($5.94, was $6.74)”
• “Fresh Sweet Corn on the Cob ($0.25 each, was $0.68)”
• “Fresh Red Cherries 2.25 lb. bag ($5.63, was $11.18).”

The keyword here is “rollback.” For Walmart, rollbacks are a temporary price reduction that show customers how much they are saving for a limited time (e.g., 90 days). For summer fruits like fresh cherries, these rollbacks can clearly be dramatic, as the harvest rolls in. In the first quarter of 2026, Walmart featured some 7,200 rollbacks, showing that the budget retailer cuts prices independently of government requests.

The cost of these temporary price reductions is often borne by the supplier. That is, Walmart does not bear the cost of rollbacks; it obtains the goods at lower prices and passes on those lower costs to the consumer. It could be that individual suppliers had run higher profit margins, that the corporate behemoth Walmart simply forced its suppliers to run a loss for a limited time on select goods, or that temporary circumstances such as the calendar resulted in a temporary decrease in production costs.

But a fourth option holds the key to all the success of the free market for the past several centuries. Sometimes, businesses can achieve lower costs through real innovation (e.g. mechanical farming equipment, assembly lines, more efficient management, etc.). In a competitive market, these innovations are passed along to consumers in the form of cheaper products. They also greatly increase worker productivity, allowing workers to earn more money that can stretch further.

Innovation doesn’t happen in every product every day. But it does happen sometimes, and it happens more often when businesses are free from central control or coercion and can adapt to changing circumstances and experiment with new things. When a general retailer sells as many different types of goods as Walmart does, sourced from many suppliers, there are bound to be numerous suppliers achieving innovation in any given year, enabling Walmart to offer their products at lower prices.

Absent deflation (where inflation turns negative), which can cause other economic ills, innovation is the chief engine to drive down costs in an economy. But innovation runs at its own pace, independent of central planners. All they can do is keep inflation low and foster conditions in which innovation can flourish.

President Trump closed his missive by exhorting other businesses to follow Walmart’s example. “Walmart is stepping up in a big and bold way, and other Retailers should follow the lead of these absolute Patriots,” he declared. Will they do so? Ultimately, the answer does not depend on whether President Trump asks them nicely, or even whether he threatens them. Businesses will lower prices when a variety of conditions drives down the costs of production, and when free competition incentivizes them not to charge more than their competitors.

In sum, businesses set their prices based on what makes economic sense, not based on what politicians demand.
