a16z Crypto: Predictive market contract settlements face arbitration bottlenecks

a16z Crypto published an article pointing out that the large-scale development of prediction markets faces a bottleneck in contract settlement determination, with the adjudication mechanism simultaneously acting as "judge, jury, and executioner." The article mentioned the incident at the beginning of the year where Venezuelan President Maduro was reportedly captured by the US military. Polymarket denied that Venezuela was invaded and ruled the related market as "No," which sparked controversy. a16z Crypto believes that prediction markets struggle to balance official information and consensus from credible reports during contract execution, making the adjudication mechanism susceptible to manipulation.
