Kalshi grew 100x in four weeks with a team of 25 people.
In 2024 Kalshi sued its own regulator to list US election contracts. It won weeks before the presidential vote.
What came next:
1. The whole team lived in the office for four weeks
2. 2M+ new customers in about two weeks
3. $2B+ in volume
4. Sign-ups and deposits broke, so they had to slow growth down
Six years of regulatory work, then one month to make it count.
That month turned Kalshi into the company now worth $40B.
