Kalshi founder defends betting data on U.S. election amid manipulation concerns

Tarek Mansour, founder of the Kalshi prediction market, refuted manipulation concerns surrounding former U.S. President Donald Trump’s 20-point lead over Vice President Kamala Harris on Polymarket by presenting comparable data from his platform, Cointelegraph reported. “The median bet size on Harris is larger than the median bet size on Donald Trump," he argued, with $85 for Harris compared to $58 for Trump, and more users are betting on Trump to win. To further demonstrate that the results are free from bias, Mansour also emphasized that Kalshi operates solely in the U.S., countering claims of foreign manipulation. Previously, speculation about manipulation in prediction markets had arisen when Trump’s chances of winning the upcoming election surpassed 60%.
