Regulatory uncertainty intensifies as President Trump resists stricter oversight despite personal ties to key platforms, while critics question CFTC's capacity and cite risks of market abuse, insider trading, and manipulation.

Regulatory concerns grow as volumes surge

As reported by Financial Times, betting activity on U.S. prediction markets is accelerating quickly, with Bernstein estimating volumes could quadruple this year and reach $1 trillion by 2030. Kalshi and Polymarket, the two best-known platforms cited in the report, are valued at $22 billion and $9 billion respectively, as contracts increasingly extend beyond sports into politics, geopolitics and other public events.

Supporters argue the products offer a legitimate form of risk-taking and can help aggregate information more effectively than some traditional forecasting tools. The report says Financial Times analysis finds prediction markets have slightly outperformed other markets in forecasting Federal Reserve rate moves since 2023, and they also beat pollsters in the 2024 election race.

Critics, however, warn that the sector combines those forecasting benefits with significant market integrity risks. Concerns include weak liquidity and transparency in some contracts, the scope for insider trading, and ambiguity over how certain event-based contracts are defined, which can make them vulnerable to manipulation.

Trump stance raises conflict questions in Washington

Political oversight is becoming a central issue because President Donald Trump appears unlikely to support tougher restraints on the sector despite acknowledging last month that the world has become "somewhat of a casino." That position is drawing added attention because Donald Trump Jr is described as an adviser to Kalshi and a major investor in Polymarket, while Commerce Secretary Howard Lutnick is also linked to the industry.

The White House is now pushing for the Commodity Futures Trading Commission to hold exclusive authority over the sector, reflecting the view that digital trading crosses state borders. But critics argue the CFTC lacks the resources for robust enforcement, and former Securities and Exchange Commission chair Gary Gensler says that approach conflicts with earlier congressional rulings.

The broader policy concern is that weak supervision could deepen perceptions of self-dealing in Washington while allowing unethical or abusive betting activity to spread. That includes fears over unchecked insider trading, speculative behavior among retail users and contracts tied to events where the act of betting itself may influence outcomes.
