According to Odaily Planet Daily, Kalshi launched the US election prediction market contract in October after the court ruled in its favor, and the trading volume exceeded US$30 million in just three weeks.

However, it still lags behind Polymarket, which had trading volume of about $40 million in early January to early February and recently exceeded $2 billion.

Kalshi Markets sees Republican candidate Trump leading Democratic opponent Harris by 14 percentage points. These odds must come only from U.S. nationals (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 cryptocurrencies, while Kalshi’s are settled in regular dollars.
