Kalshi says it reached a $22 billion valuation in a funding round completed in May, alongside annualized trading volume of $178 billion, placing the federally regulated U.S. prediction-market operator at the center of a fast-growing but increasingly contested market for event-based contracts.
The Manhattan-based company allows users to trade on the outcome of sports contests, elections, economic releases, and other events. Its growth has come with mounting legal and political pressure, including a lawsuit brought by New York Attorney General Letitia James that challenges whether Kalshi can offer its contracts in the state without complying with New York gambling rules.
Kalshi rejects that argument, saying its contracts fall under federal commodities regulation and that states cannot order the platform to stop operating. The dispute could help define how far federal approval from the Commodity Futures Trading Commission, or CFTC, shields prediction-market operators from state gambling laws.
A federal license meets state gambling rules
Kalshi operates nationwide under CFTC oversight, a structure that differs sharply from the licensing model used by conventional sports-betting companies. Gambling operators typically need permission in each state where they offer services. Kalshi’s position is that event contracts traded on its federally regulated platform are financial products rather than wagers governed by state gaming authorities.
New York is not alone in examining that distinction. More than 10 states have introduced legislation this year aimed at regulating prediction markets, according to the information supplied by the company’s founders. Those proposals reflect concern that platforms offering contracts tied to sports and other public events could compete with state-licensed bookmakers without facing the same tax, consumer-protection, and market-access rules.
The legal fight arrives as sports trading remains Kalshi’s largest business line, although its dominance has declined. Chief Executive Tarek Mansour said sports accounted for roughly 95% of platform volume last year but now represents closer to two-thirds, as cryptocurrency, politics, and macroeconomic markets attract more activity.
That change gives Kalshi a more diversified revenue base while also exposing it to more sensitive questions. Political and economic contracts can be used as real-time gauges of collective expectations, and prediction-market odds have increasingly appeared in media coverage of elections and financial developments. Yet the same markets can create risks when participants possess confidential information about government decisions, corporate events, or security matters.
Insider-trading concerns follow expansion
Recent episodes across the prediction-market sector have intensified scrutiny of whether users can trade on nonpublic knowledge. The source material cited a U.S. soldier involved in the attempted capture of Venezuelan President Nicolás Maduro who placed a related trade on Polymarket, a separate prediction-market platform. It also cited a White House teleprompter operator who traded Kalshi contracts tied to the content of a Donald Trump speech.
Such cases test a central claim made by regulated event-contract venues: that transparent markets and identity verification can deter misconduct more effectively than anonymous betting environments. Mansour said Kalshi requires identity checks for all users, makes trading data publicly visible, and uses automated surveillance intended to identify suspicious patterns. He said the monitoring system draws on the approach used by the New York Stock Exchange.
Those controls may be easier to apply on a centralized, federally regulated venue than in decentralized prediction markets, where participants can often transact through crypto wallets with fewer identity checks. They do not eliminate the challenge of proving that a trader acted on material, nonpublic information, particularly when the event concerns politics, defense, or government policy rather than a publicly traded company.
A New York Times investigation referenced in the source material reported that the prediction-market sector’s expansion has coincided with reduced CFTC staffing and a softer enforcement posture. The agency’s capacity will be closely watched as platforms add contracts, trading volumes rise, and state officials push back against federal preemption.
Liquidity is concentrated among specialist traders
Kalshi’s rapid volume growth does not necessarily mean its markets are evenly driven by a large retail audience. Mansour said fewer than 2% of users classified as “super forecasters” account for 70% to 80% of trading volume. Many other users make only occasional trades.
That concentration matters for the way odds are interpreted. Prediction-market prices are often presented as a probability: a contract trading at 60 cents can imply an estimated 60% chance of the event occurring. Mansour argues that prices become more accurate when participation increases, and said some political markets reach between $50 million and $100 million in size.
Large pools of activity can make prices harder to move with a single trade and can absorb competing views. Yet a market dominated by a small group of highly active participants may reflect the information, risk tolerance, and strategies of those traders more than a broad public consensus. Price signals can be useful, but they remain market estimates rather than verified forecasts.
Founders keep a lean operating structure
Kalshi was founded in 2018 by Mansour and Chief Operating Officer Luana Lopes Lara after they graduated from the Massachusetts Institute of Technology. Mansour, who grew up in Lebanon, handles external matters, while Lopes Lara, who is from Brazil, leads internal operations.
The company opened to the public in 2021 and now has roughly 200 employees working from an open-plan office in Manhattan’s Meatpacking District. Mansour has described Kalshi as operating with few management layers, allowing teams to reorganize around projects. He has also said he and Lopes Lara work weekends regularly.
The company’s valuation and reported trading figures show how quickly prediction markets have moved beyond a niche political-forecasting product. Kalshi’s next phase will depend less on office structure or headline volume than on whether courts and regulators accept its federal-market framework for sports and event contracts, and whether its safeguards can withstand sharper scrutiny as those markets become larger and more consequential.
