Polymarket has refused to settle bets placed on the United States military action in Venezuela last weekend, even though American forces evidently went into the country, arrested the country’s president, and transported him to New York. Traders are now accusing the world’s largest prediction market of redefining the terms of their winning bets after the outcome became politically and financially sensitive. At issue is a contract that asked, “Will the US invade Venezuela by…?” where bettors chose deadlines in January. They insist the operation met the conditions of an invasion, regardless of its speed or casualties. The frenzy continued when an anonymous trader scored a massive profit after US President Donald Trump confirmed Maduro’s capture over the weekend. On Friday, the account invested roughly $30,000 in contracts predicting Maduro would be removed from power by January 31, 2026. When news broke on Saturday morning that the Venezuelan leader had been flown out of the country, the position’s gains had exceeded $430,000. Polymarket then ruled that the US action did not qualify as an invasion under the terms of the contract. The platform said the operation failed to meet its definition of military action intended to control Venezuelan territory. Once that clarification was issued, the odds of a US invasion before the end of January collapsed to below 5%, wiping out the payouts for traders who had backed the outcome. Polymarket holds $10.5 million worth of bets on invasions According to the New York Post, Polymarket has seen more than $10.5 million wagered on invasion-related contracts this year alone. Most of that volume was concentrated on the January 31 deadline, with more bets placed on March and December expirations, Cryptopolitan found . On its website, Polymarket said the contract refers specifically to “US military operations intended to establish control,” and that “President Trump’s statement to ‘run’ Venezuela while referencing ongoing talks with the Venezuelan government does not alone qualify the snatch-and-extract mission to capture Maduro as an invasion.” The explanation failed to calm traders, many of whom are adamant that the action fits the reasonable understanding of an invasion. Users flooded the platform’s discussion forums, bashing Polymarket for “moving goalposts” and trying to cover up facts. “So it’s not an invasion because they did it quickly and not many people died?” one bettor wrote on Polymarket’s site. A trader using the pseudonym Skinner posted on the forum that “Polymarket has descended into sheer arbitrariness.” “Words are redefined at will, detached from any recognised meaning, and facts are simply ignored. That a military incursion, the kidnapping of a head of state, and the takeover of a country are not classified as an invasion is plainly absurd.” Polymarket user accused of insider trading The dispute also led to chatter about the timing and scale of some of the Venezuela-related wagers, which were compared to a separate controversy last year when a trader correctly bet on the winner of the Nobel Peace Prize. The anonymous account that won over $400,000 was created on December 26, and in the days that followed, it placed several bets in four contracts on US actions in Venezuela . When the user wagered more than $32,000 that Maduro would be removed from power by the end of January, the “yes” outcome was priced at just a 7% probability. Yet, Polymarket’s chief executive, Shayne Coplan, has previously asserted that insider trading might be beneficial to the public. “What’s cool about Polymarket is that it creates this financial incentive for people to go and divulge the information to the market,” Coplan said at an Axios Business event last year. The platform’s competitor, Kalshi, on the other hand, bars insider participation and prohibits government officials from trading on contracts in their areas of influence. According to Kalshi’s rules, a government official involved in US decision-making would have been blocked from making a trade linked to the Maduro operation. “Kalshi explicitly prohibits insider trading of any form, including government employees trading on prediction markets related to government activity,” spokeswoman Elisabeth Diana told reporters. “We’re looking at the specifics of the bill, but we already ban the activity it cites and are in support of means to prevent this type of activity.” Sharpen your strategy with mentorship + daily ideas - 30 days free access to our trading program
