最新报道:Prediction markets saw major funding rounds last week, with Polymarket raising $2 billion at a $9 billion valuation from Intercontinental Exchange and Kalshi securing $300 million at a $5 billion valuation. Polymarket's Shayne Coplan became the youngest self-made billionaire following the raise. Kalshi captured 60% market share against Polymarket in September, with combined volume hitting $1.44 billion. While Kalshi operates off-chain and recently partnered with Robinhood for sports betting integration, Polymarket runs fully onchain with transparent market data.
