Prediction markets are moving into a far more restrictive political environment in Washington after nearly $64 billion in transaction volume over the past year pushed lawmakers to act. What had been treated as a fast-growing corner of financial experimentation is now being recast as a venue that may require hard statutory limits rather than voluntary platform controls.
The new proposals are not narrowly targeted. Taken together, they would restrict who can trade, narrow which contracts can be listed, increase penalties for misuse and, in some cases, shift authority back toward state-level regulation. That means the debate is no longer about whether guardrails are needed, but about how aggressive they will become.
Congress Is Moving From Oversight to Restriction
Several of the bills now circulating in Congress approach the issue from different angles but share a common concern: that political and sensitive event contracts create insider-trading and integrity risks that self-regulation may not be able to contain. Some measures focus on banning specific categories such as sports, casino-style events, elections, war and terrorism, while others focus on prohibiting participation by presidents, vice presidents, lawmakers, senior officials and even immediate family members.
The range of proposals makes the shift especially notable. The Prediction Markets Are Gambling Act would cut off sports and casino-style event contracts on CFTC-regulated platforms, while the PREDICT Act would bar senior federal officials and their families from political-event trading and impose penalties that include a 10% fine and forfeiture of profits. Other proposals go even further by targeting contracts tied to elections, government actions, military operations and other sensitive public events.
That accumulation of bills signals that lawmakers are no longer content to leave this issue to platform policy teams. The STOP Corrupt Bets Act, the End Prediction Market Corruption Act, the Public Integrity in Financial Prediction Markets Act, the BETS OFF Act, the Prediction Markets Security and Integrity Act and the Event Contract Enforcement Act all point in the same direction: more law, less discretion.
Platforms and Compliance Teams Will Have to Rebuild Their Playbooks
Platforms such as Kalshi and Polymarket have already introduced their own restrictions, and Kalshi has even publicly supported some legislative action. But the emerging congressional approach would force a deeper operational reset by turning product design, identity checks and surveillance obligations into legal requirements rather than optional governance choices.
That would affect product architecture directly. Engineers may have to remove or redesign entire categories of contracts, tighten onboarding around age and identity verification, and build systems capable of identifying covered persons or detecting trades that appear linked to nonpublic information. The burden would not stop at launch design; it would extend into audit trails, post-trade review and remediation processes when issues surface after execution.
If federal law narrows some forms of market activity while also returning more authority to states, firms could end up operating under a more fragmented map of enforcement risk and gambling-law exposure. That possibility would make product expansion slower, more expensive and more dependent on jurisdiction-by-jurisdiction analysis.
The market consequences could cut in two directions at once. A narrower product set and higher compliance costs may compress margins and weaken user persistence, but stricter rules could also reduce information asymmetry and restore a degree of public trust that these platforms have struggled to secure. In practical terms, firms will need to prepare for both outcomes at the same time.
Congress has now made prediction markets a live regulatory front rather than a niche policy topic. The real question is no longer whether voluntary platform guardrails are enough, but whether exchanges can adapt quickly enough if statutory restrictions begin to replace them.
