Creating prediction markets (and suing the CFTC) with Tarek Mansour and Luana Lopes Lara
By Stripe
Categories: Product, Startup
Summary
Kalshi built the first CFTC-approved prediction market by choosing regulatory compliance over growth, spending 3 years pre-launch and turning down the offshore path—then proved the strategy right by trading $10B+ monthly and winning a major election lawsuit in 2024.
Key Takeaways
- Choose the hardest problem first: Kalshi identified 'Can we do this legally in the US?' as the biggest blocker, not market growth, and solved regulatory approval before launch despite competitors going offshore.
- Financial services and healthcare require 'ask permission' not 'ask forgiveness'—FTX-style failures prove you cannot retroactively structure money movement or high-risk industries without upfront regulatory frameworks.
- Individual contract approval model: Every single prediction market contract requires CFTC filing with 24-hour review window, creating real-time regulatory oversight rather than blanket approval.
- Co-founder balance thesis: Pair an optimistic risk-taker with a paranoid expected-value calculator (trader mindset). This split prevents blind spots and creates sustainable decision-making frameworks.
- Timeline reality check: 3 years from YC 2019 to regulated launch (2022), then 2 more years to winning an election lawsuit (end of 2024). Legal clarity compounds growth—not a 6-month regulatory process.

They spent four years pre-launch fighting for regulatory approval to build the first onshore prediction...
