Interactive Brokers Chair Says Prediction Markets Are the Next Frontier in Trading

Benzinga reported Wednesday that Interactive Brokers Chair Thomas Peterffy believes prediction markets are positioned to become a transformative asset class for institutional investors. Speaking on Bloomberg’s “Odd Lots” podcast in April, Peterffy argued the emerging category could soon rank alongside futures and options as a mainstream trading instrument.

Peterffy’s Case for Prediction Markets

Peterffy contended that traditional equity markets fall short when investors need to express direct views on macroeconomic or geopolitical outcomes. Stocks reflect company-level expectations, he noted, but they filter out much of the broader environmental context shaping returns.

Prediction markets, by contrast, let participants stake real capital on specific future outcomes. That dynamic, Peterffy told Benzinga via the podcast, concentrates expertise in a way that surveys and analyst reports cannot. Participants who are wrong lose money, creating stronger incentives for accuracy.

He also suggested the markets could eventually reduce the financial industry’s reliance on traditional economists and research analysts for forecasting.

IBKR ForecastTrader and the Liquidity Problem

Interactive Brokers has already moved beyond rhetoric. The firm recently expanded IBKR ForecastTrader, a dedicated prediction market platform, to give clients a structured venue for trading event-based contracts.

Liquidity remains the most significant obstacle. Peterffy acknowledged that contract volumes today are a fraction of what trades in equities or options markets daily. He drew a direct parallel to the earliest years of listed options trading in the early 1970s, when thin markets and limited participation constrained growth. Volumes in options eventually reached millions of contracts daily as the product matured.

Prediction markets may close that gap faster, Peterffy suggested, because event contracts are structurally simpler than options and easier for non-specialist investors to interpret.

Consolidation and Institutional Focus

To accelerate adoption, Interactive Brokers is reportedly building a consolidated pricing feed that aggregates data from Kalshi and other prediction market platforms. The approach mirrors how equity traders today compare quotes across multiple exchanges to find the best price.

Peterffy was explicit that IBKR intends to keep its offering focused on economically material questions tied to client portfolios. Sports wagering and celebrity-outcome markets that populate some competing platforms are outside the firm’s scope.

Background: Prediction Markets Come of Age

Prediction markets have existed in various forms for decades, but regulatory uncertainty long limited their scope in the United States. Kalshi’s legal battles with the Commodity Futures Trading Commission, which the firm ultimately won, helped establish that event contracts tied to economic outcomes fall within regulated derivatives frameworks. That ruling opened the door for mainstream brokers like Interactive Brokers to participate directly.

The sector has attracted growing institutional attention since the 2024 U.S. election cycle demonstrated that market-implied probabilities on platforms like Polymarket could outperform traditional polling in certain conditions.
