White House staffers received a stark reminder last month: keep confidential information out of the betting markets. On March 24, 2026, the White House Management Office circulated a staff-wide email, warning against using nonpublic government information to place trades or bets—especially on prediction markets like Kalshi and Polymarket. The timing was no coincidence. Just a day earlier, President Donald Trump had announced a sudden five-day pause on planned military strikes against Iran’s power plants and energy infrastructure, citing ongoing talks with Tehran. That announcement, posted on Truth Social around 7 a.m. on March 23, was preceded by a flurry of unusual activity in financial markets that has since drawn scrutiny from lawmakers and regulators alike.
According to Bloomberg and Dow Jones Market Data, at 6:49 a.m.—fifteen minutes before Trump’s post—contracts covering at least six million barrels of Brent and West Texas Intermediate crude oil were sold within two minutes. This amounted to hundreds of millions of dollars, dwarfing the average of 700,000 barrels typically traded during that period over the previous five days. In total, more than $760 million worth of oil futures changed hands in less than two minutes. The scale and speed of these trades immediately set off alarm bells among market observers and politicians, who wondered whether someone had capitalized on advance knowledge of a major U.S. policy shift.
The White House email, obtained by multiple media outlets including CBS News and The Wall Street Journal, was unequivocal. "Recent press reports have raised concerns about government officials using nonpublic government information to place wagers on online prediction markets, such as Kalshi or Polymarket," it read. The message continued, "It is a criminal offense for anyone to use nonpublic information to buy or sell these contracts," and reminded staff that "misuse of nonpublic information by government employees for financial benefit is a very serious offense and will not be tolerated." Staffers with questions were referred to the White House Counsel’s Office.
White House spokesperson Davis Ingle responded to the growing speculation in statements to several outlets, including BBC and CBS News. "President Trump has been crystal clear: while he seeks a strong and profitable stock market for everyone, members of Congress and other government officials should be prohibited from using nonpublic information for financial benefit. The only special interest that will ever guide President Trump is the best interest of the American people." Ingle added, "All federal employees are subject to government ethics guidelines that prohibit the use of nonpublic information for financial benefit. However, any implication that Administration officials are engaged in such activity without evidence is baseless and irresponsible reporting."
Despite these assurances, the suspicious timing of the trades has not gone unnoticed. Representative Ritchie Torres, a Democrat from New York serving on the House Financial Services Committee, sent letters to both the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC), urging them to investigate. Torres wrote, "What kind of trader would make a massive trade at 6:49 a.m., 15 minutes before a market-moving presidential announcement with billions of dollars at stake and without a hedge? The only plausible answer to that question is an insider trader. Any other alternative is a statistical impossibility."
The scrutiny hasn’t stopped with traditional futures markets. On April 7, at least 50 newly created accounts on Polymarket—a crypto-based, global prediction market—placed substantial bets that the U.S. and Iran would agree to a cease-fire, just before President Trump announced the deal at 6:30 p.m. Eastern Time. These bets generated hundreds of thousands, and in some cases more than $600,000, in profit for a handful of accounts. The anonymous nature of the accounts, identified only by blockchain strings, has made it difficult to determine whether insiders were involved. Nevertheless, the episode has fueled debate about whether prediction markets are being exploited using privileged government information.
Senator Richard Blumenthal of Connecticut took action as well, sending a letter to Polymarket on April 9. He pressed the company to explain its oversight and regulatory practices, especially regarding trades linked to U.S. national security matters. Blumenthal wrote, "These repeated, illicit bets raise significant concerns about the mishandling of confidential information on Polymarket, and calls into question whether it is taking adequate steps to prevent, deter, and report national security leaks and gambling over matters of life-and-death."
In response to mounting concerns, both Kalshi and Polymarket announced new measures to curb the risk of insider trading. Kalshi, which operates under CFTC regulation, said it would prohibit political candidates from trading in markets related to their own campaigns, and bar individuals involved in college or professional sports from trading on events they participate in. Polymarket, which re-entered the U.S. in late 2025 after acquiring a CFTC-licensed exchange, said it would explicitly ban users from trading on contracts where they might have inside knowledge or the ability to influence outcomes. Despite these steps, the bulk of Polymarket’s activity remains on its unregulated global platform.
The controversy has also spurred legislative action. On March 23, Senators Adam Schiff (D-CA) and John Curtis (R-UT) introduced a bill to ban prediction markets from listing contracts that resemble sports bets or casino-style games. The following day, a bipartisan group in the House introduced the "Preventing Real-time Exploitation and Deceptive Insider Congressional Trading Act," which would ban members of Congress, the President, executive branch officials, and their families from trading on prediction markets tied to political events. Senator Andy Kim of New Jersey, another vocal critic, warned, "Corruption and exploitation are thriving right now within the gaps and loopholes of prediction markets. This manipulation leaves the select few winning big, at the expense of working Americans."
Prediction markets aren’t new, but their popularity has surged in recent years. Platforms like Kalshi and Polymarket allow users to bet on everything from sports outcomes to central bank decisions and election results. The allure is clear: these markets offer a way to profit from world events, and, for some, a sense of being ahead of the curve. But as the recent incidents show, when the stakes involve national security or the timing of war and peace, the ethical—and potentially legal—lines become sharply drawn.
So far, there is no public evidence that White House employees or other government officials have personally profited from insider trades. Still, the convergence of high-stakes policy decisions and rapid-fire market moves has prompted a reckoning in Washington about how to regulate this new frontier. As the boundaries between politics, financial markets, and technology continue to blur, the pressure is on lawmakers, regulators, and market operators to keep the playing field fair—and to keep the public’s trust intact.
The debate over prediction markets and insider information is far from over, but for now, White House staff have been put on notice: when it comes to betting on the future, the rules are clearer—and the consequences, potentially dire.
