[Polymarket Refuses to Classify U.S. Military Action as 'Invasion,' Sparking User Dissatisfaction] Multiple Polymarket users have expressed dissatisfaction with the platform's refusal to classify the recent U.S. military action in Venezuela as an 'invasion' and settle the related prediction market accordingly. Polymarket argued that the actions in question did not meet the market's definition of 'invasion' and therefore declined to pay out profits to participants who bet on 'the U.S. invading Venezuela.' Some users believe that the U.S. military's entry into Venezuela, the arrest of the president and their spouse, and the announcement of U.S. 'takeover' of affairs should constitute an invasion. However, the platform's description stated that the market only referred to 'military actions aimed at establishing control,' and the actions in question did not meet the criteria for determination. The platform has not responded to media inquiries. Opinion pieces have pointed out that the concentration of rule interpretation authority and transparency issues in prediction markets could pose risks, especially in significant geopolitical or military events.
