Blockchain-powered prediction markets are at the center of explosive allegations of insider trading linked to geopolitical events during President Donald Trump's second term. A BBC investigation, corroborated by on-chain data, reveals a consistent pattern of suspiciously timed, highly profitable trades placed minutes or even seconds before major market-moving announcements.
The report details several instances where large, well-timed bets preceded Trump's public statements on critical events. On March 9, 2026, a massive spike in short oil positions occurred 47 minutes before Trump called into CBS News to suggest the US-Israel-Iran conflict was "pretty much" over, causing oil to drop 25%. A similar pattern emerged on March 23, with unusual trade volumes appearing 14 minutes before a Trump Truth Social post about peace talks with Iran.
The focus sharpens on crypto prediction markets like Polymarket and Kalshi. A new Polymarket account named "Burdensome-Mix" placed $32,500 in late December 2025 on Venezuelan President Maduro being removed from power. When US forces seized Maduro on January 3, the account collected $436,000, then renamed itself and went silent. In February, six separate accounts collectively bet on a US strike on Iran by February 28. When the strikes happened, they split $1.2 million, with five accounts never used again.
The connection deepens with the involvement of Donald Trump Jr., who is both an investor in and a member of the advisory board for Polymarket, and also advises Kalshi. He has not commented on the allegations.
These events occur against a backdrop where Bitcoin and risk assets have become highly sensitive to Trump's statements. A University of Oxford study noted sharp market swings following rapid U.S. tariff policy changes, creating "fantastic trading opportunities" for those with advanced knowledge. Lawmakers, including Senator Adam Schiff and Congressman Stephen Lynch, have called for investigations into potential insider trading or market manipulation, citing patterns of large, profitable trades ahead of major policy announcements.
Despite the immutable, public evidence provided by blockchain timestamps and wallet addresses, enforcement remains a significant hurdle. Insider trading laws have technically covered U.S. government officials since 2012, but no prosecution has ever been brought under that statute. Regulatory bodies like the SEC and CFTC have not taken public action, and a financial regulation professor told the BBC that even with overwhelming evidence, there's "a strong chance that no one will be prosecuted."
