Polymarket Withholds Millions as Venezuela Invasion Market Remains Unsettled
Polymarket has refused to settle nearly $11 million in bets on a potential U.S. invasion of Venezuela, raising questions about prediction markets’ ability to resolve ambiguous political events. The company argues that the mission to capture Nicolás Maduro does not meet the event contract’s definition of invasion.
The platform resolved a separate “US forces in Venezuela by…?” contract in favor of the “yes” position hours after Saturday’s raid. However, Polymarket says it will only settle the invasion contract if the U.S. military “commences a military offensive intended to establish control over any portion of Venezuela.”
Contract Language Fuels Dispute
After Maduro’s capture by U.S. special forces early Saturday, President Donald Trump said the U.S. would dictate Venezuela’s policies. Prices on the invasion question jumped after the raid but fell below 5% when Polymarket declined to settle.
On January 4, Polymarket added a note stating that Trump’s statement about “running” Venezuela does not alone qualify as an invasion. The majority of the wagers were placed on a January 31 deadline.
The decision has sparked anger among bettors who wagered on the contract, with users taking to Polymarket’s comment section to express frustration.
“Polymarket has descended into sheer arbitrariness,” wrote user Skinner (via Financial Times). “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.”
Insider Trading Concerns Resurface
The controversy has revived concerns about traders exploiting information advantages on prediction markets. The scrutiny follows a similar episode last year involving a winning bet on the Nobel Peace Prize.
An anonymous account created on December 26 placed multiple bets on Venezuela-related contracts days before the operation. The trader wagered over $32,000 on Maduro being removed from power when “yes” was priced at 7 cents, implying a 7% probability.
When Maduro was extracted from the country on January 3, the market settled at “yes”. The position paid out over $400,000. The Wall Street Journal reported the account increased its exposure just hours before explosions were reported in Caracas.
The same account also traded the disputed invasion market. A $1,000 bet placed at 6 cents was sold at 18 cents, locking in a 200% return before prices fell back to around 5%.
The trades have intensified regulatory pressure. Congress member Ritchie Torres (D-NY) has proposed legislation that would prohibit insiders “from engaging in covered transactions involving prediction market contracts.”
Kalshi Fumbles Win Total Markets
Kalshi incorrectly graded some NFL win-total markets this week. The company reimbursed only the original stake to users who held correct positions, rather than paying the full winnings.
“wtf…people who bet 49ers win total correctly were only reimbursed cost and not winnings when it was graded wrong? And they won’t just eat it?,” gambling industry analyst Dustin Gouker wrote on X.
Following backlash, Kalshi reversed course, with a company spokesperson stating, “Upon review, we have decided that users who held correct ‘Yes’ positions at the time of Expiration shall be paid out their full contract settlement value of $1. … Everyone has been paid in full, including winnings.”
“Love the wording here, ‘we have decided’ as if they are doing you a favor out of the goodness of their hearts,” Evan Koch wrote on X. “Not like, well, you won, and we completely messed up.”
Resolution Risk as Operational Challenge
Resolution disputes are a recurring issue in prediction markets. Traders raised similar concerns in 2019 over how PredictIt resolved a Trump impeachment contract, underscoring long-standing frustrations around political outcomes.
On Polymarket, contract resolution is handled by UMA Protocol rather than the platform itself. Disputed markets can be escalated to UMA token holders, who vote on how contract terms should be interpreted.
The Venezuelan markets reflect this structure. While contracts tied to Maduro’s removal have already resolved, the invasion market remains unsettled due to disagreement over whether the underlying event meets the contract’s definition.
Trading volume across Venezuela-related contracts on Polymarket has exceeded $87 million. However, the unresolved invasion contract now trades as a low-probability outcome, with bettors assigning just a 4% chance of a payout by January 31.
