In the latest developments of U.S. election betting, Kalshi has seen over $30 million in presidential betting following a favorable court ruling. Despite being a regulated platform, Kalshi trails behind Polymarket, which surpassed $2 billion in trades since its launch. The current market grants Donald Trump a 14 percentage point lead over Kamala Harris, with Kalshi's terms allowing only U.S. citizens to participate in betting. Kalshi’s co-founder, Tarek Mansour, addressed concerns about market manipulation, stating that the median bet on Harris is larger than on Trump, implying that Trump's odds reflect genuine support rather than manipulation. The average bet size on Polymarket for Trump is reported at $210, with limited large bets affecting the overall market. Trump has mentioned Polymarket favorably during a rally, highlighting its relevance in this election cycle. While there are discrepancies in swing state markets, the platforms continue to engage bettors with their unique features—Kalshi operates with regulatory backing while Polymarket utilizes cryptocurrency for bets.
