- Suspiciously timed bets on Polymarket suggest potential insider knowledge of US-Iran cease-fire talks before Trump's public announcement. While the situation is developing, the news introduces geopolitical uncertainty, which could negatively impact market sentiment, but the effect is likely to be minimal unless the cease-fire fails or escalates.

Investing.com -- A group of Polymarket accounts placed large bets on a U.S.-Iran cease-fire before President Donald Trump announced productive talks between the two nations on Monday.
Ten recently opened accounts wagered around $160,000 on Polymarket’s U.S.-Iran cease-fire market, betting that a cease-fire would occur by March 31 or April 15, according to Bloomberg. The accounts stand to gain over $1 million if a cease-fire happens by the end of the month.
Trump posted on Truth Social on Monday morning that the U.S. and Iran had very good and productive conversations about resolving the war in the Middle East. However, the Polymarket bets were placed before Trump made this information public.
The accounts were identified by Lirrato on X on Sunday and recirculated by PolymarketHistory. After Trump’s post on Monday, the prediction-market positions from those 10 accounts had increased by more than $300,000 in unrealized gains.
One account, trading under the handle NOTHINGEVERFRICKINGHAPPENS, drew attention for its betting history. The account was opened in late February, and its first two trades were a $7,600 bet on the U.S. striking Iran by Feb. 28 and a $11,283 bet on a strike by March 1. The account won over $85,000 on those two bets.
The same account is now betting $8,005 on a U.S.-Iran cease-fire by March 31 and an additional $15,614 on a cease-fire by April 15. Those two bets have already gained over $30,000 in value.
The size, timing and track record of these bets have raised questions about whether the Polymarket accounts belong to insiders with political connections to the U.S. or Iran who may have knowledge about the current state of diplomacy.
