About
Tarek Mansour co-founded Kalshi in 2018 and spent seven years turning event contracts from a regulatory impossibility into a $22 billion company — raising $1 billion led by Coatue in May 2026, double the mark set five months earlier. Born in California and raised in Lebanon, he studied mathematics and computer science at MIT, interned at Goldman Sachs and traded at Citadel Securities, then founded Kalshi with MIT classmate Luana Lopes Lara. Kalshi won a CFTC exchange licence, beat the regulator in court to list election contracts through the 2024 election, and in April 2026 won the first federal appellate ruling that commodities law preempts state gambling law for sports event contracts.

- More
- Kalshi sued the CFTC over election contracts and won at district court in September 2024; the D.C. Circuit denied the regulator's stay, letting congressional-control contracts trade through the election. In April 2026 the Third Circuit affirmed Kalshi's injunction against New Jersey — the first federal appellate holding that the Commodity Exchange Act preempts state gambling law for sports event contracts. Says most business advice is 'trash' and that founders should take risks instead; has ruled out an IPO before 2027.
