In this episode of Odd Lots, host Joe Weisenthal and Tracy Alloway welcome Thomas Peterffy, founder and chairman of Interactive Brokers, to discuss IBKR's new prediction market platform, Forecast Trader. Peterffy argues that prediction markets—when focused on serious, economically consequential questions like recessions, AI adoption, and climate change—can provide valuable consensus forecasts for institutional investors, much like stock markets offer insight into company futures. He contrasts IBKR’s institutional-focused approach with retail platforms like Polymarket and Kalshi, which are dominated by sports and pop culture bets. Peterffy explains that IBKR’s unique position as both broker and exchange allows it to build a more professional, liquid market, and he shares his long history with market innovation, including early automated trading and his own options pricing model. He also makes a provocative case for eliminating insider trading laws, arguing that information should be made public immediately to benefit society. The conversation explores the potential for prediction markets to become standard reference data, the challenges of contract standardization, and the transformative role of AI in finance. Despite skepticism about the timeline, Peterffy remains confident that these markets will become essential tools for decision-making.
Prediction markets can provide clear, probabilistic forecasts on macroeconomic and societal risks—like recessions or climate change—offering better decision-making tools than traditional economic models.
Interactive Brokers is differentiating itself by focusing exclusively on serious, economically relevant contracts and excluding sports and pop culture, targeting institutional investors rather than retail gamblers.
The success of prediction markets hinges on liquidity, which IBKR believes can be accelerated through its existing institutional client base and a consolidated market feed across platforms.
Peterffy advocates for eliminating insider trading laws, arguing that information should be made public immediately to benefit society, even if it temporarily disadvantages some traders.
AI is not a fundamentally new paradigm but a higher-level programming language that enables more powerful, probabilistic modeling—aligning well with the probabilistic nature of prediction markets and options pricing.

The History of Prediction Markets and Insider Trading
“I still say to you that I think the best thing we could do about inside information is just to get the news out there as fast as possible and forget about persecuting people.”
