Predictive markets are shaking up the boundaries between financial innovation and state regulation. Gary Gensler, former head of the SEC and the CFTC, has just taken a position in a debate that could redefine the rules of the game in the United States. A conflict with colossal stakes.

In brief
- Gary Gensler argues that sports-related prediction markets fall under state regulations, not the CFTC.
- Gensler argues that these contracts are not swaps and do not cover economic risks, but relate to sports betting.
- States risk losing tax revenue if the CFTC wins its case, while platforms like Kalshi could operate freely.
Gary Gensler: Predictive markets must not circumvent state laws
Former SEC and CFTC Chairman Gary Gensler filed an amicus brief in the Sixth Circuit Court of Appeals arguing that sports-related prediction markets are outside federal jurisdiction. According to him, Congress has never included sports betting in the definition of swaps (derivative products regulated by the CFTC), because these contracts are not used to hedge economic risks, but to speculate on sports results.
Additionally, Gary Gensler points out that states must retain their authority on those activities that generate essential tax revenue and fall under their local regulations. Several entities, such as the American Gaming Association and Native American tribes, support this position. They argue that platforms like Kalshi violate their sovereign rights by offering unregulated betting.
What impacts for the ecosystem of predictive markets and beyond?
If the CFTC prevails, platforms like Kalshi could operate freely under federal supervision. Thus depriving states of millions of dollars in taxes. Conversely, a victory for the States would force these actors to register locally, under penalty of criminal sanctions. This debate goes beyond sports betting because it questions the balance between financial innovation and regulatory sovereignty.
A Supreme Court decision could set a precedent for other sectors. Particularly cryptos, where the tension between federal and state regulation is already palpable and influences the price of bitcoin. Investors and entrepreneurs are closely monitoring this issue, aware that its outcome could reshape the landscape of alternative markets.
Between innovation and regulation, Gary Gensler and the standoff around predictive markets illustrates a central question: who should control the future of finance? The answer could well influence far beyond sports betting. And you, do you think that States should keep control?
