Polymarket Sued for $170,000 Over Disputed Trump Bet

Prediction market platform Polymarket is facing a lawsuit for $170,000 in damages from a user alleging a denied payout on a winning bet. The dispute centers on a wager regarding whether President Donald Trump would utter a specific word.

What Happened

Prediction market platform Polymarket is confronting a lawsuit from a participant who claims a substantial winning bet payout was withheld, according to The Daily Hodl. The bettor, Jesús Manuel Gonzalez Hernandez, has filed suit against Polymarket for $170,000, asserting he correctly predicted that President Donald Trump would say “Khamenei.”

Polymarket facilitates trading on the outcomes of current events. As part of its recurring series titled “What will Trump say this week?”, participants engaged in yes-or-no bets regarding whether Trump would use the words “Khamenei” or “Ayatollah” during the week of March 15th. Hernandez reportedly purchased 170,000 “yes” shares for $300, which would have resulted in a $170,000 payout had his bet been settled as a win.

Hernandez’s lawsuit alleges that Trump indeed said “Khamenei” twice while aboard Air Force One during the specified week, as reported by The Daily Hodl. Lawyers representing Hernandez cite White House transcripts of the exchange and video of President Trump speaking as evidence supporting their client’s claim. Conversely, Polymarket reportedly resolved the market against Hernandez, referencing a potential mispronunciation or a reference to Ruhollah Khomeini, a former Iranian leader who passed away decades prior. The legal arguments from Hernandez’s side emphasize that the established rules for the market did not mandate exact pronunciation and that the surrounding context of the discussions was aligned with active conflicts rather than historical figures.
