Could 300 year-old British law sink U.S. sports betting?

Mickey Kim / August 8, 2025

The possible impact of Commodity Futures Trading Commission (CFTC) regulation of Kalshi sports prediction contracts—and the shadow of the Statute of Anne—on the U.S. gaming industry is a story of legal nuance, regulatory turf wars and the ever-blurring boundary between betting and financial speculation.  As Bloomberg’s Matt Levine wryly observed, the distinction between “predicting” and “gambling” is at the heart of a jurisdictional and philosophical debate that could reshape the American gaming landscape.

Kalshi: Where Prediction Meets Regulation

Kalshi, a federally-regulated prediction market, lets users trade on the outcome of real-world events—including sporting events—by buying “yes” or “no” contracts on specific questions.  If your prediction is right, you profit; if not, you lose your stake.  The mechanics are eerily similar to a sports bet, but Kalshi insists it’s not gambling—it’s “prediction.”

This distinction isn’t just marketing: it’s a legal lifeline.

The CFTC oversees financial contracts on future events for commodities and economic matters like interest rates or the S&P 500.  A farmer may sell a “futures” contract to deliver 5,000 bushels of corn in 6-months to lock in a price and protect/hedge against a potential price decline.  A speculator may buy that contract from the farmer, predicting corn prices will rise.

Kalshi operates under this federal umbrella, arguing that its markets are financial contracts, not wagers. This allows Kalshi to offer contracts nationwide, even in states where traditional sports betting remains illegal.

The CFTC’s own rules muddy the waters. They prohibit event contracts “related to gaming,” a term that Kalshi has argued in court filings should not apply to sports outcomes.  The courts, at least for now, have sided with Kalshi, granting it the right to offer sports event contracts as federally-regulated financial contracts, not state-regulated bets.

State vs. Federal: The Regulatory Tug-of-War

The U.S. gaming industry is a patchwork of state laws, each with its own rules for sports betting.  State-regulated sportsbooks like DraftKings are licensed in specific jurisdictions, pay state taxes and operate under strict local oversight.  Kalshi, by contrast, claims a federal passport, operating in all 50 states under CFTC regulation—even in states that have sent cease-and-desist letters, such as Nevada and New Jersey.

This has sparked a turf war.  States argue Kalshi’s contracts are functionally indistinguishable from sports bets and should be subject to state gaming laws.  Kalshi counters that its peer-to-peer, market-based model is fundamentally different: it matches buyers and sellers of opposing contracts, rather than acting as “the house” setting odds and taking bets.

The legal battles are ongoing.  The outcome will determine whether prediction markets can bypass state gaming restrictions by donning the cloak of financial contracts.

The Statute of Anne: An Old Law Casts a Long Shadow

The Statute of Anne (aka the Gaming Act of 1710) was enacted in Britain during the reign of Queen Anne to curb gambling excesses and made gambling debts unenforceable and allowing losers to recover their losses.  These principles still linger in the gaming laws of over 30 states.

A fascinating twist is not only did the Statute of Anne allow losers to sue to recover losses, if the loser did not sue within six months, a third-party could sue and potentially recover triple the amount lost. Proving “old laws never die; they just wait for a clever lawyer to dust them off,” Ohio Gambling Recovery LLC recently filed a lawsuit in Ohio against Kalshi and others seeking to recover losses.

If Kalshi’s contracts are deemed to be “gambling” and not “predictions,” the Statute of Anne puts them (and all others offering similar contracts) at risk for forfeiting millions.  The challenge for regulators is to draw a line between socially useful risk management and socially harmful gambling—a line that is increasingly difficult to see as platforms like Kalshi “gamify” prediction and blur the distinction between betting and investing.

Industry Impact: Disruption, Innovation and Risk

If the CFTC’s regulatory approach prevails, the U.S. gaming industry could be transformed in several ways:

  • National Access: Kalshi and similar platforms could offer sports prediction contracts nationwide, bypassing state gaming restrictions and taxes. Traditional sportsbooks would face new competition from federally regulated exchanges with potentially lower costs and better odds for consumers.
  • Regulatory Arbitrage: States could lose revenue and regulatory control as bettors migrate to federally regulated platforms.
  • Consumer Protection Risks: As prediction markets “gamblify” their interfaces—using betting terminology, real-time odds and engagement-driven features—the risk of addiction and financial harm increases. Critics argue that these platforms replicate the behavioral hazards of gambling while escaping many of its regulations.
  • Legal Uncertainty: The unresolved tension between state and federal authority, and the ambiguous status of prediction contracts under the Statute of Anne’s legacy, means that the industry could face years of litigation and regulatory flux.

The stakes are not just financial but societal.  The rise of prediction markets as quasi-gambling venues raises questions about addiction, fairness and the proper role of government in regulating risk.  In the end, it’s not just about who wins the game—it’s about who gets to set the rules.
