The White House issued guidance to staff prohibiting bets on prediction markets like Polymarket and Kalshi due to insider trading risks heightened by rapid developments in the Iran war and oil prices. The memo comes amid scrutiny over potential misuse of non-public information affecting markets. Lawmakers have raised concerns about such platforms during geopolitical tensions.

The White House has reminded staff that using nonpublic information to bet on prediction markets violates ethics rules and can be criminal, prompted by unusual oil-futures activity and Polymarket positions that preceded Iran-related announcements. No evidence has established that any official placed such bets, yet the episode exposes how easily sensitive geopolitical developments can be monetized on lightly regulated platforms. The real stakes are whether lawmakers and regulators can update rules for these new markets before the next crisis turns national-security timing into a tradable commodity.
What outlets missed
Most outlets downplayed or omitted that the March 24 memo was a broad reminder of existing ethics rules covering all nonpublic information, not a targeted reaction to specific Iran bets or an admission of wrongdoing. They also underplayed platform responses: both Kalshi and Polymarket announced new internal bans on insider trading shortly after the scrutiny, including barring participants with potential influence over outcomes. Bipartisan legislation existed beyond the Democratic bills highlighted, including a House measure with Republican co-sponsors aimed at executive-branch families. Finally, coverage rarely noted the absence of any confirmed investigation, charge or identified White House account despite months of anonymous trading on crypto-based platforms, leaving the 'insider' narrative suggestive rather than evidentiary.
The prospect that nonpublic details from the volatile U.S.-Iran conflict could translate into private profits has left many Americans uneasy. A White House memo sent March 24 reminded staff that betting on platforms like Polymarket and Kalshi with inside information violates ethics rules and can constitute a criminal offense. The guidance arrived one day after President Trump announced on Truth Social a pause in threatened strikes on Iranian infrastructure, citing productive talks with Tehran.
At the center of the story lies a single unresolved tension: prediction markets now let anyone wager on war timelines, cease-fires and oil shocks, yet those closest to the decisions face growing suspicion whenever trades align too neatly with announcements. Bloomberg reported an unusual spike in oil futures at 6:49 a.m. New York time on March 23. Contracts for at least six million barrels of Brent and West Texas Intermediate crude traded in two minutes, far above the recent average of 700,000 barrels in the same window, according to data cited by Bloomberg and the Financial Times. Separately, the Wall Street Journal described new anonymous Polymarket accounts that profited by correctly timing a subsequent cease-fire announcement. No evidence has surfaced linking any White House employee to those positions.
