According to *The New York Times*, the competition between prediction market platforms Kalshi and Polymarket has extended to regulatory, legal, funding, and business collaboration fronts. Sources say that months before the FBI raided Polymarket founder Shayne Coplan's residence in 2024, Kalshi's lawyers met with federal prosecutors from the Southern District of New York to explain Polymarket's operations and pointed out its potential accessibility to U.S. users. Before ICE decided to invest in Polymarket, Kalshi CEO Tarek Mansour and a16z partner Alex Immerman reportedly communicated separately with ICE executives, which some insiders viewed as an attempt to block the deal. The two sides have also clashed over CFTC licenses, trademarks, talent, partners, and state-level regulations, with the competition going far beyond typical business rivalry. https://(wublock123.com)/news/nyt-kalshi-vs-polymarket-regulatory-legal-funding-battle-64970
