According to the Wall Street Journal report and the legislative draft RYA26191, Senators Adam Schiff and John Curtis will introduce a bipartisan bill this Monday to enforce a sports betting ban on prediction markets. The measure seeks to veto casino-style contracts on CFTC-regulated platforms, affecting weekly transactions worth 3.8 billion dollars.
Republican Senator John Curtis has stated that too many young people are exposed to addictive gambling under a framework that should be state-managed. This legislative offensive arises at a time when the Commodity Futures Trading Commission (CFTC) is attempting to consolidate its federal oversight, while lawmakers argue that these activities belong to the exclusive control of states.
The jurisdictional duality between federal regulators and state gambling laws
This legislative move is not an isolated event, given that it adds to the recent classification of event contracts as financial assets by the CFTC. This new regulatory pressure comes just as the Senate pushes measures against war markets, seeking to halt profiting through global violence events and death-related contracts.
The magnitude of the economic impact is considerable, since sports markets dominate the total volume of these platforms, representing almost all of their current liquidity. According to Dune data, 47.7% of Polymarket’s weekly notional volume comes from sports, while at Kalshi the figure rises to a staggering 78.8% of the total traded.
If we add both platforms, the weekly sports betting volume recently surpassed the 3.8 billion dollar barrier, evidencing a structural dependency of the sector. Unlike previous cycles such as 2020, where interest was purely electoral, the infrastructure of the blockchain has allowed for a massive scalability of sports gambling.
Can prediction markets survive without the volume of sports betting?
Historically, prediction markets were conceived as collective wisdom tools for geopolitical events, but their transformation into high-frequency digital casinos poses systemic risks. Legislative interest has intensified since the Senate questioned the ethics of betting on armed conflicts, setting a clear precedent for this new restriction.
The proposed ban would generate a liquidity vacuum that, far from eradicating gambling, could displace users towards unregulated offshore platforms. This phenomenon is reminiscent of the 2011 online poker ban, where the lack of legal alternatives fostered the proliferation of websites without consumer protection.
Unlike traditional derivatives markets, sports event contracts lack a commercial risk hedging purpose, which weakens their legal defense under the Commodity Exchange Act. The current ambiguity allows local judges to intermittently block operations, creating an uncertainty that drives institutional investors away from the sector.
The immediate future of these platforms will depend on their ability to pivot towards macroeconomic indicators and corporate event markets, moving away from the volatile sports sector. The coming months are expected to be critical, since the CFTC will evaluate public comments on its regulations while Congress debates this new restrictive bill.
