Prediction markets have exploded into the mainstream of American wagering, and nowhere is that clearer than at Kalshi, the exchange that now processes billions in sports-related trades. But explosive growth has invited equally intense scrutiny. A sweeping new CFTC proposal, state lawsuits, and a looming Supreme Court showdown could reshape the entire prediction-market landscape in 2026. Here is what is happening and why it matters for anyone who bets.
Quick answer: Prediction markets let users trade contracts on real-world outcomes, including sports. In 2026, Kalshi hit record volume but faces a CFTC rulemaking that would ban certain sports contracts, plus criminal charges and lawsuits in multiple states.
What Are Prediction Markets?
Prediction markets are exchanges where users buy and sell contracts tied to the outcome of future events. If you think a team will win, you buy "yes" shares; if the event happens, each share pays out a fixed amount. Because the contracts trade like financial instruments, they fall under federal commodities regulation rather than state gambling law, a distinction at the heart of the current legal battles. To understand how this differs from traditional wagering, see our sports betting guide.
Kalshi's Explosive Growth
Kalshi's numbers are staggering. In May 2026, the platform's sports prediction markets hit $10.44 billion in trading volume, roughly 60 times the volume of its election markets. More than $344 million was traded on the 2026 World Cup alone as of mid-June, with over $200 million of that pouring in once the tournament kicked off.
The company is now valued at $22 billion following a major funding round, and it has signed celebrity ambassadors including Lionel Messi and Timothée Chalamet to broaden its mainstream appeal.

The CFTC Crackdown
Federal regulators are responding to the boom with a heavy hand. The Commodity Futures Trading Commission released a 267-page proposal that would rework the rules governing prediction markets. Under the draft, exchanges like Kalshi could be barred from offering certain sports-related contracts, particularly those tied to officiating outcomes or player injuries, the kinds of granular markets that resemble traditional prop bets.
The proposal signals that Washington wants clearer boundaries between regulated financial markets and what critics call gambling in disguise. For an industry built on offering markets on almost anything, these limits could significantly narrow Kalshi's most popular sports offerings.
State Lawsuits and Criminal Charges
The pressure is not only federal. Several states have moved aggressively against prediction-market operators:
- Arizona: In March 2026, the state attorney general filed criminal charges against Kalshi, alleging it was running an illegal gambling business.
- Wisconsin: In April 2026, the attorney general sued Kalshi, Coinbase, Polymarket, and others, alleging they bypass state gambling laws.
- US Senate: In May 2026, the Senate banned its members and staff from betting on prediction markets like Kalshi.
These actions reflect a broader tension: states that have legalized and taxed sports betting see prediction markets as an end-run around their regulatory frameworks. Our gambling guides track how these legal questions are evolving across the country.
The Supreme Court Looms
The fundamental question, whether sports event contracts are federally regulated financial products or state-regulated gambling, is heading toward the Supreme Court. The outcome could either legitimize prediction markets nationwide or force them to abandon sports entirely. Few legal battles in the gambling world carry higher stakes, and the ruling will reverberate across both the betting and financial industries.
What It Means for Bettors
For now, prediction markets remain accessible in much of the country, offering an alternative to traditional sportsbooks. But the regulatory cloud means the landscape could shift quickly. Bettors should understand that prediction-market contracts carry different risks, protections, and tax treatment than licensed sportsbook wagers.

Why Sportsbooks Are Watching Closely
Traditional sportsbooks have a major stake in this fight. Prediction markets like Kalshi can offer sports contracts nationwide under federal oversight, sidestepping the state-by-state licensing, tax, and advertising rules that licensed operators must follow. That regulatory asymmetry is precisely what has drawn objections from both states and established betting companies, who argue it creates an uneven playing field. If prediction markets are allowed to continue offering sports event contracts, they could siphon significant volume away from licensed sportsbooks in regulated states.
At the same time, some operators are exploring whether to launch their own prediction-market products, hedging against an outcome where the federal model prevails. The next 12 months will be decisive in determining whether prediction markets become a permanent fixture of American sports wagering or a regulatory footnote.
The Global Context
The United States is not alone in grappling with prediction markets. Regulators worldwide are wrestling with how to classify event contracts that blur the line between financial instruments and gambling. The American outcome, particularly any Supreme Court ruling, will likely influence how other jurisdictions approach the question. For a multibillion-dollar industry growing this fast, the stakes could hardly be higher.
Frequently Asked Questions
What is a prediction market?
A prediction market is an exchange where users trade contracts on the outcome of future events, such as sports or elections, with payouts based on whether the event occurs.
Is Kalshi legal?
Kalshi operates as a federally regulated exchange, but several states have challenged its sports markets in court, and a CFTC proposal could restrict certain contracts. Its legal status is actively contested.
How is a prediction market different from a sportsbook?
Prediction markets trade contracts under federal commodities rules, while sportsbooks operate under state gambling licenses. The two have different protections, tax treatment, and legal frameworks.
Could prediction markets be banned from sports?
Possibly. The CFTC's proposal would bar certain sports contracts, and a pending Supreme Court case could determine whether prediction markets can offer sports betting at all.
Conclusion
Prediction markets are at a crossroads in 2026, caught between record-breaking growth and intensifying legal pressure. Whether Kalshi and its rivals emerge stronger or are forced to retreat from sports will shape the future of American wagering.
