Prediction Markets See Explosive Growth
Prediction markets are booming, with Polymarket's weekly volume surpassing Kalshi's at $1.93 billion. Both platforms are now reportedly eyeing $20 billion valuations, reflecting a growing shift toward financial markets with "skin in the game" as a source for accurate information over traditional social media.
The surge toward $20 billion valuations builds on significant recent fundraising. Kalshi was valued at approximately $11 billion in a December 2025 funding round, while Polymarket reached a $9 billion valuation in October 2025 following a major investment commitment from Intercontinental Exchange, the parent company of the NYSE. This growth is fueled by a massive uptick in trading activity. The combined monthly trading volume for both platforms soared to $18.3 billion in February 2026, a dramatic increase from under $2 billion in August 2025. Kalshi, founded in 2018 by Tarek Mansour and Luana Lopes Lara, has reported an annualized revenue run rate approaching $1.5 billion. The two platforms operate under different regulatory frameworks in the U.S. Kalshi is a designated contract market regulated by the Commodity Futures Trading Commission (CFTC). Polymarket, founded by Shayne Coplan in 2020, has historically restricted U.S. users but is planning to launch a fully regulated American version of its platform later this year. While the CFTC has recently signaled a more supportive federal stance, the industry faces significant legal challenges at the state level. Regulators in several states argue that contracts on certain events, particularly sports, constitute unlicensed gambling and should be subject to state gaming laws, creating a federal-state jurisdictional conflict. The expanding scope of tradable events, from sports and elections to more controversial topics like international conflicts, has attracted scrutiny from lawmakers. In response to concerns about national security and insider trading, U.S. Representatives Blake Moore and Salud Carbajal recently introduced bipartisan legislation aimed at prohibiting markets based on war, assassinations, and other sensitive topics.
