- Prediction markets — where traders bet peer-to-peer on real-world outcomes — now process more than $3 billion in weekly notional volume on Polymarket and Kalshi combined, more than double year-end 2024 levels, with the two platforms valued at a combined $31 billion
- A 2024 court victory by Kalshi over the CFTC opened the door to election and sports contracts, while the Trump administration has since dropped probes into Polymarket and embraced the industry; new CFTC chair Mike Selig has pledged to help prediction markets fight state-led lawsuits
- The Trump family is deeply embedded: Donald Trump Jr. advises both Polymarket and Kalshi, his firm made an eight-figure investment in Polymarket, and Trump Media has announced prediction markets powered by Crypto.com on Truth Social
- Critics warn of serious risks: no consumer protections required (unlike sportsbooks), insider trading vulnerabilities, potential for bettors to manipulate outcomes, and the same addictive loss cycles as gambling — without the safeguards
What Happened?
Prediction markets have exploded from a niche academic concept into a mainstream financial product processing billions of dollars weekly. Platforms like Kalshi and Polymarket allow traders to buy and sell event contracts — structured like financial derivatives — betting on whether real-world events will occur: elections, weather, sports results, geopolitical outcomes, even whether a sex toy will be thrown onto a basketball court. Because they are regulated by the CFTC as derivatives exchanges rather than by state gaming authorities as gambling platforms, they have been able to expand rapidly and offer contracts that traditional sportsbooks cannot. A landmark 2024 court victory by Kalshi against the CFTC removed the agency’s ability to block election-related contracts, and the Trump administration has since embraced the industry — dropping enforcement probes and pledging regulatory support.
Why It Matters?
Prediction markets sit at the intersection of finance, gambling, and information aggregation — and the line between those categories is dissolving fast. Intercontinental Exchange has invested $1.6 billion in Polymarket; DraftKings and FanDuel have launched their own prediction market exchanges; Robinhood has partnered with Kalshi and is now building a competing platform; and CME Group has entered the space. The structural argument for prediction markets — that they aggregate dispersed information more efficiently than polls or expert forecasts — was lent credibility by the 2024 election, when Polymarket and Kalshi showed Trump as a heavy favorite even as surveys said the race was a coin flip. But the same information edge that makes them appealing to policymakers and investors creates serious insider trading risks: a series of trades on Iran-related contracts that appeared to anticipate Trump’s ceasefire announcement before it became public has already prompted Congressional concern and calls for legislation.
What’s Next?
The regulatory patchwork is intensifying: Nevada, New York, Massachusetts, and Arizona have filed lawsuits arguing prediction market contracts are illegal gambling under state law — with Arizona going so far as filing criminal charges against Kalshi. The CFTC’s new chair has pledged to defend the industry against these suits, creating a direct federal-state conflict. Congress is considering bills that would bar government officials and other insiders from trading on events where they have a conflict of interest. The Trump family’s financial entanglement with the largest platforms also raises questions about whether the administration’s regulatory accommodation is driven by market efficiency arguments or personal financial interest. As volume, valuations, and political stakes all rise, the prediction market industry’s regulatory status is shaping up as one of the more consequential financial policy fights of the next two years.
