Co-founder and CEO of Kalshi, a U.S.-regulated prediction market and event-contract exchange. He co-founded the company with Luana Lopes Lara after studying at MIT and working as a quantitative trader at Goldman Sachs and Citadel.

Kalshi co-founder Tarek Mansour argues that the prediction-market company’s defining choices — refusing to pivot, suing the CFTC, and keeping a deliberately chaotic founder-led organization — all followed from treating Kalshi as a vehicle for an “everything exchange,” not as a conventional startup to be optimized. In his account, the company’s legal victory before the 2024 election mattered because years of regulatory patience, product work, and co-founder disagreement with Luana Lopes Lara left it ready to use the opening.
