Kalshi, which launched the U.S. election prediction market contract in October after a court ruled in its favor, has traded over $30 million in just three weeks. It still trails Polymarket, which traded around $40 million between early January and early February, the first month of its presidential bets, and recently traded over $2 billion. Kalshi Market believes that Republican nominee Donald Trump has a 14-point lead over Democratic opponent Kamala Harris, and it is reported that these odds must only come from US nationals (and permanent residents), as Kalshi's terms and conditions prohibit foreigners from trading on the platform.
