The Backstory

Sports contracts pushed prediction markets into gambling’s territory

Kalshi’s removal of athlete injury markets marks a sharper regulatory turn in a fight that has been building since prediction platforms began expanding from elections and economic indicators into sports. The immediate issue was narrow: contracts tied to when specific athletes would return to play. The broader conflict is not. Regulators, leagues, sportsbooks and state officials are testing whether sports event contracts are financial derivatives under federal law or gambling products that must follow state betting rules.

Kalshi has argued that its contracts trade on a federally regulated exchange and should not be treated like sportsbook wagers. State officials have taken the opposite view, saying the company is offering sports betting without licenses, tax payments or consumer protections required of gambling operators. That divide has produced lawsuits across multiple states and an increasingly active role for the Commodity Futures Trading Commission, which both regulates Kalshi and has intervened to protect the company’s ability to operate as a national market.

The injury markets intensified that debate because they moved beyond game outcomes into the health status of individual players. Contracts involving Luka Dončić, Anthony Edwards and Malik Nabers raised questions that traditional betting regulators and leagues have long treated as sensitive: access to medical information, incentives tied to injuries and the potential for harassment or manipulation around athletes’ availability.

The CFTC has tried to draw lines while defending federal control

The CFTC’s request that Kalshi remove injury-related contracts followed the agency’s June proposal on sports event contracts. That framework identified contracts based on the duration, severity, occurrence or diagnosis of a specific athlete’s injury as especially problematic because they could create financial incentives around health and invite misuse of confidential medical information. The agency’s position suggested that even if sports event contracts remain under federal derivatives law, not every sports-linked market will be acceptable.

At the same time, the CFTC has aggressively defended its jurisdiction against state challenges. In New York, the agency used emergency authority to order Kalshi to keep operating despite a lawsuit from Attorney General Letitia James, who alleged the platform was running an illegal gambling business. The CFTC said the state was trying to force event contracts under an “iron curtain” of gaming laws before courts could issue final rulings, according to the agency’s emergency action allowing Kalshi to continue in New York.

That move reflected the agency’s central argument: federally registered derivatives exchanges must function as interstate markets rather than state-by-state gambling businesses. If individual states can block trades or impose local sports betting rules, the CFTC says the national structure of derivatives markets could fracture. States counter that this position lets prediction markets bypass gambling safeguards simply by changing the label on products that resemble wagers.

The CFTC also has sought to police how prediction markets present themselves to consumers. In August, the agency warned operators not to display contract prices in American odds format, saying sportsbook-style odds could mislead users about the nature of derivatives trading and obscure market depth and pricing effects. That warning against sportsbook-style odds showed the CFTC trying to preserve a distinction between financial products and gambling even as the underlying sports markets grew more similar to betting.

States are challenging the national-market claim

State regulators and attorneys general have focused on consumer protection, age limits, taxation and the integrity systems that licensed sportsbooks must follow. New York’s lawsuit alleged Kalshi exposed residents, including people under the state’s legal gambling age of 21, to financial risks while avoiding state gambling taxes and controls. The state sought a temporary restraining order, restitution and civil penalties that could reach at least $36 billion.

Michigan has presented a similar challenge. After an Ingham County judge temporarily blocked Kalshi from offering sports event contracts in the state, the CFTC ordered the company to honor pending Michigan trades. The agency said Kalshi could not cancel trades based on customer residence because federal law requires impartial access to a single national derivatives market. Michigan Attorney General Dana Nessel’s office called the move an intrusion on the state’s authority to regulate companies operating within its borders. The dispute, outlined in Michigan’s response to the CFTC’s order on Kalshi trades, highlighted the operational problem at the center of the fight: if Kalshi must follow state sports betting restrictions, its national exchange model becomes harder to maintain.

The litigation is not limited to Kalshi. Polymarket has faced its own setbacks in Michigan, where a federal judge denied a preliminary injunction after concluding its sports-event contracts did not fall under CFTC regulation. That ruling added uncertainty for rivals seeking to rely on federal oversight to avoid state-by-state gambling rules.

For states, the stakes are financial and regulatory. Sports betting is licensed, taxed and monitored locally. If prediction markets can offer similar products nationwide under federal derivatives rules, states risk losing control over a lucrative and politically sensitive sector. For Kalshi and other platforms, adverse rulings could force geofencing, age controls and compliance systems that would make their operations look much more like online sportsbooks.

Geolocation became a proxy for the larger compliance fight

The practical consequences of the jurisdictional fight are visible in geolocation. Licensed sportsbooks rely on location checks to ensure customers place bets only where gambling is legal. Prediction markets have not operated under the same state-based geofencing model, a distinction that has alarmed compliance technology providers and state regulators.

Kalshi’s growth has unsettled companies such as GeoComply, Radar and Xpoint, whose systems help sportsbooks verify a bettor’s location and detect proxy betting or fraud. According to Sportico, Kalshi’s national CFTC license allows it to operate without the location-tracking tools required of state-licensed betting operators, raising concerns that prediction markets could erode a compliance market worth hundreds of millions of dollars. Those concerns were detailed in reporting on Kalshi’s expansion and geolocation firms.

The geolocation issue matters because it turns a legal theory into a market structure. If prediction markets are national derivatives exchanges, they can avoid the patchwork of state approvals that defines online sports betting. If they are gambling operators, geolocation becomes essential. Kalshi has resisted adopting such systems in litigation, arguing that the costs would cause irreparable harm. State officials see that resistance as evidence that the platform is evading the rules other betting companies must follow.

The question also affects larger operators watching the space. FanDuel’s partnership with CME Group to develop federally regulated event contracts suggests traditional sportsbooks may seek their own path into CFTC-supervised products. That could blur the line further, especially if gambling companies use federal derivatives structures to reach customers in states where sports betting remains restricted or tightly controlled.

Athlete welfare added pressure that pure market arguments could not answer

Injury markets touched a nerve because they tied financial outcomes to individual athletes’ bodies. Sports leagues have spent years trying to protect confidential medical information and manage betting-related integrity risks. A market on whether an athlete will return by a specific date creates incentives for traders to seek nonpublic information from trainers, team employees or others close to a player. It also could increase pressure on athletes already facing public scrutiny around injuries.

The broader betting industry has been confronting the consequences of wagering-related abuse. Fanatics Sportsbook, for example, plans to ban customers who threaten or harass athletes, coaches or officials online through a program with IC360 and Signify Group. That initiative, described in Fanatics’ plan to restrict bettors who abuse athletes on social media, reflects a growing recognition that betting losses can spill into harassment and threats. Injury markets add another layer by making the athlete’s health itself the event being traded.

The NFL’s objection to Kalshi’s injury markets fit that concern. Leagues may tolerate, partner with or profit from regulated betting on game outcomes, but contracts tied to medical status raise integrity and labor issues that are harder to manage. Even if such contracts are legally derivatives, they may be commercially toxic for leagues and politically difficult for regulators to defend.

Kalshi’s withdrawal does not resolve the central legal battle. The company remains locked in cases over whether sports contracts fall under federal commodities law or state gambling regulation. But the CFTC’s intervention signals that federal oversight will not be a blank check. The agency is defending prediction markets as national financial exchanges while also warning that some sports products, especially those tied to injuries, may cross lines that threaten market integrity, athlete welfare and public confidence.

That balance will shape the next phase of the sector. Prediction markets want the reach of federal finance law. States want gambling controls preserved. Leagues want limits on products that put athletes at risk. The injury-market removal shows those pressures are no longer theoretical.
