Ethereum co-founder Vitalik Buterin earned around $70,000 after correctly betting against “Crazy Mode” on decentralized prediction platform Polymarket. The wager was tied to a market predicting whether an extreme or unlikely scenario would occur, with Buterin taking the opposing, more conservative view. His win drew attention on social media, highlighting both Polymarket’s growing popularity and Buterin’s engagement with onchain prediction markets, which are increasingly seen as tools for gauging sentiment and probabilities around real-world and crypto-related events.
