Kalshi, a U.S.-based prediction market platform, has secured a $1 billion investment led by Coatue Management, resulting in a $22 billion valuation, according to reports from the Wall Street Journal and Bloomberg. The funding round, which nearly doubles the company’s valuation from December 2025, underscores growing investor confidence in the burgeoning event-based trading sector.
The rapid ascent of Kalshi places it in a competitive position against Polymarket, its primary rival. Both companies had reportedly been targeting valuations around $20 billion earlier in March, signaling a potential surge in investment within the prediction market industry. Polymarket recently announced an exclusive partnership with Major League Baseball, aiming to offer prediction markets tied to baseball games and events, a move intended to broaden its appeal, and legitimacy.
The rivalry between Kalshi and Polymarket has manifested in unconventional marketing tactics. In February, Kalshi announced it would provide free groceries to Modern Yorkers, a promotional effort quickly mirrored by Polymarket, which opened a pop-up grocery store a week later. These initiatives highlight the companies’ efforts to attract users and generate publicity.
Kalshi’s growth is largely attributed to a 2020 decision by the Commodity Futures Trading Commission (CFTC) to grant it regulatory approval, allowing it to operate legally within the U.S. The platform gained further traction in January 2025 with the introduction of wagers on sports events.
Polymarket’s path to legitimacy has been more challenging. The CFTC banned the platform from operating in the U.S. In 2022 after determining it was offering event contracts without proper authorization. The situation escalated in 2024 with an FBI raid on the New York City apartment of Polymarket CEO Shayne Coplan. However, the CFTC granted Polymarket approval in 2025, paving the way for its return to the U.S. Market.
Despite the influx of investment and growing popularity, prediction markets are facing increased scrutiny. Arizona recently filed criminal charges against Kalshi, alleging the company was operating an illegal gambling operation within the state. Kalshi is currently defending itself against over 20 lawsuits concerning its legal standing. Concerns about potential insider trading on both platforms have too surfaced, notably following an incident on Polymarket where a trader reportedly earned over $400,000 by correctly predicting the outcome of a political event involving Nicolás Maduro.
Kalshi’s revenue run rate is nearing $1.5 billion, fueled by billions in weekly trading volume during peak events, according to sources cited in a Yahoo Finance report. The company has completed at least eight funding rounds since its founding in 2019, attracting backing from prominent venture capital firms including Sequoia Capital, Andreessen Horowitz, and ARK Invest.
