Polymarket, a decentralized prediction market, is embroiled in a dispute over the definition of a U.S. "invasion" of Venezuela, affecting a high-stakes wager worth millions. Despite military actions by the U.S. against Venezuela, Polymarket ruled these did not constitute an "invasion" under its rules, invalidating the "Yes" option and sparking protests from bettors. This highlights ongoing challenges in prediction markets regarding the interpretation of complex real-world events. The controversy underscores a broader issue in decentralized prediction markets: the difficulty of defining "truth" when outcomes depend on subjective interpretations rather than clear, objective criteria. Polymarket's reliance on the decentralized oracle UMA allows token holders to vote on outcomes, which can lead to manipulation by major players. This case exemplifies the limitations of the "code is law" principle, as subjective judgment often remains necessary in interpreting complex events.
