Odaily Planet Daily News: Kalshi launched the U.S. election prediction market contract in October after receiving a favorable ruling in court, and in just three weeks, the trading volume has exceeded $30 million. However, it still lags behind Polymarket, which had a trading volume of about $40 million from early January to early February (the first month its presidential election prediction contracts were open), with recent trading volume exceeding $2 billion. The Kalshi market believes Republican candidate Trump is leading Democratic opponent Harris by 14 percentage points. These odds must come solely from U.S. citizens (and permanent residents) because Kalshi's terms and conditions prohibit foreigners from trading on the platform. In contrast, Polymarket prohibits U.S. traders from using the platform but does not require a KYC process. Polymarket's bets are denominated in cryptocurrency, while Kalshi's bets are settled in regular U.S. dollars. (CoinDesk)
