How Kalshi prevents markets from incentivizing harm

with @mansourtarek_ @rhackett

In this episode of web3 with a16z crypto, host Robert Hackett talks with Kalshi Cofounder and CEO Tarek Mansour about how prediction markets are enabling people to trade directly on real-world events — from elections to inflation — and what this means for the future of finance and forecasting.

Tarek explains why prediction markets aren’t gambling, how regulation has been central to Kalshi’s success, and why the company is embracing crypto and stablecoins as key components of its international strategy. He also discusses lessons learned about policy, product design, and staying compliant while innovating at the frontier.

Topics include:

• How prediction markets make society "smarter"
• The role of regulation in fintech innovation
• Why Kalshi started with crypto payments
• Lessons from FTX and the importance of compliance
• Building consumer trust and network effects
• Tarek’s take on productivity, leadership, and even… kombucha
