Prediction markets platforms operated by firms such as Kalshi and Crypto.com faced intense scrutiny Wednesday during a U.S. Senate Commerce Committee hearing, where lawmakers questioned the industry's advertising practices, potential for athlete cheating and competition with regulated tribal gaming operations. The two-hour session underscored the regulatory uncertainty surrounding a sector that has grown rapidly under Commodity Futures Trading Commission oversight.

Market Context

The hearing arrives as prediction markets have expanded beyond political forecasting into sports outcomes, drawing ire from traditional gaming operators and state regulators. Five states—Arizona, Connecticut, Illinois, Minnesota, and New York—have moved to restrict or prohibit these platforms, prompting the CFTC to file lawsuits defending its jurisdiction over event contracts classified as derivatives.

The American Gaming Association, which represents casinos and sportsbooks, argues that prediction markets undermine regulated gaming operations, particularly those run by tribal nations where revenue supports reservation infrastructure. The CFTC, meanwhile, contends it has legal authority to supervise platforms registered under its rules, comparing the instruments to long-regulated commodity futures contracts.

Analysis

Senator Ted Cruz, the Texas Republican who chairs the committee, cited high-profile cases of alleged manipulation tied to gambling interests. He pointed to NBA players and coaches accused of providing insider information for bets, two MLB pitchers allegedly rigging their own pitches for money, MLS players banned for intentionally drawing yellow cards to win wagers, and UFC match cancellations due to suspected fixing. "The opportunity to make money can tempt gamblers—and sometimes even athletes themselves—to guarantee a sure bet," Cruz said.

Senator John Hickenlooper of Colorado accused prediction markets firms of deploying the "hounds of hell" through social media marketing that reaches young people despite age restrictions. The industry pushed back, with Patrick McHenry—a former House Financial Services Committee member who retired from Congress last year—arguing that average platform users are 33 years old and that no one under 18 can trade on member platforms.

Harry Levant, director of gambling policy at the Public Health Advocacy Institute, testified as a recovering gambling addict, characterizing prediction market advertising as an "avalanche of unregulated" promotion. "It's a known addictive product, just like heroin," he told senators. In response, Kalshi CEO Tarek Mansour highlighted his company's $2 million commitment to the National Council on Problem Gambling for trader health and safety initiatives.

The hearing revealed a fundamental divide over whether event contracts constitute derivatives under CFTC jurisdiction or illegal gambling under state law. Bill Miller, president of the American Gaming Association, told lawmakers that federal regulators "are absolutely not competent to handle this" and argued it was never Congress's intent to create a "federal department of gambling through the CFTC."

What to Watch

The CFTC's legal campaign against state laws will be closely watched, with Chairman Mike Selig arguing that Minnesota's proposed restrictions would turn lawful operators into "felons overnight." The agency is pursuing both litigation and a formal rulemaking process to establish tailored standards for prediction markets. Senator Cruz suggested the Supreme Court may ultimately need to resolve whether CFTC or state gambling regulators have authority over event contracts. Industry participants should monitor upcoming court rulings, potential legislative responses, and any further expansion of tribal gaming concerns into federal policy discussions.
