Thomas Peterffy on IBKR's Plan to Professionalize Prediction Markets | Odd Lots

Summary
Thomas Peterffy argues that prediction markets can become a serious tool for institutional investors if they focus on economically meaningful questions and build enough liquidity. He compares them to the stock market: both mix important and silly instruments, but the mechanism itself is not the problem. In his view, the appeal is that prediction markets let experts put money behind a consensus view on outcomes like recession risk, climate change, or AI adoption.
Peterffy says Interactive Brokers is trying to differentiate Forecast Trader by serving serious, large-scale clients rather than leaning on sports or pop-culture contracts to generate volume. He expects the market to grow slowly at first because liquidity is the main hurdle, but thinks simpler contract design can help adoption. He also says the firm plans to make contracts as fungible as possible and eventually provide leverage, though he warns leverage will create risk.
The conversation also turns to regulation and market structure. Peterffy says he wants markets to absorb information faster and argues against insider-trading rules, even after losing money himself to what he saw as inside information early in his career. He also says prediction-market data could eventually become a standard reference point, like fed funds pricing, and thinks economists may be displaced by traders expressing probabilities directly.
Key takeaways
- Peterffy thinks prediction markets will eventually be “very, very big” because they are a simple way to express probabilities and hedge decisions.
- Interactive Brokers is targeting serious institutional users, not sports bettors or pop-culture traders, as the core audience for Forecast Trader.
- He expects liquidity to be the key bottleneck, but says simpler contract design should help prediction markets grow faster than options did.
- Peterffy says the firm wants contracts to be as fungible as possible across venues so prediction markets can support consolidated pricing and execution.
- He argues that insider information should be released as fast as possible rather than policed heavily, because delays mainly help “sharks” profit longer.

How the episode opens
Early on when I started my career, I left. I lost half my initial capital based on inside the three. So I'm, I'm extremely familiar with with the damage it can cause.
But on the other hand, and in spite of that, I'm in favor of not having any, rules against insider trading. I would like all the information out there as soon as it's available. There is no.
Because, look, as a society, we're better off knowing as soon as possible anything that is knowable. Right. So why why do we have to wait forever?
First of all, when you when you are faced with a merger or acquisition situation where there most of the insider trading is happening, right? They, they, you know, this the secretary's the lawyers, everybody knows about it. They go home day to day, rise day.
Osborne's day. So eventually always filters out. So it's almost impossible to avoid.
It's very, very difficult and cumbersome. Why don't we just do away with it and let the information come out as soon as possible? Hello and welcome to another episode of the Odd Lots podcast.
I'm Tracy Alloway and I'm Joe Weisenthal. Joe, sometimes, sometimes I go on prediction markets, Yeah. And I see some of the contracts being traded.
And, you know, we hear the argument all the time that there might be a real economic reason. Yes. Why prediction market should exist.
So maybe, you know, maybe you run a studio in Hollywood. Yeah. So like it's actually really important who will be in the next cast of whatever Avengers movie is coming out.
But I have a hard time thinking that betting on whether or not Jesus Christ is going to return to the world is economically important, right? Yeah. No, I think there's a great point.
