Kalshi co-founder Tarek Mansour announced an additional $1B raise valuing the prediction-market company at $40B, with plans to expand into stocks, compute, indices, and institutional offerings. The announcement coincides with the 8th anniversary of Kalshi's YC acceptance. Mansour reflected on growing up in wartime Lebanon and his mother's sacrifice to bring the family to the US; the reposter adds a career anecdote about joining Kalshi early on a friend's advice, when it trailed Polymarket in volume and awareness.
