Prediction markets face Senate pressure over wildfire bets

Prediction markets are drawing Senate pressure over wildfire contracts. Democrats want the CFTC to examine whether such bets create arson incentives.

Senator Jeff Merkley and other Democratic senators sent a letter to Commodity Futures Trading Commission Chairman Michael Selig seeking tighter oversight of wildfire-related event contracts. Their core concern is direct: if a contract pays when a fire expands or turns deadly, a bad actor could see a financial motive to make that outcome happen.

Merkley letter targets wildfire bets

The senators wrote that the CFTC “cannot allow these prediction markets to offer unrestricted betting on wildfires,” tying the request to a severe US fire season. The letter asked whether the agency intends to act against wildfire contracts on domestic venues and offshore platforms.

The clearest example cited was Polymarket activity tied to California’s Palisades and Eaton fires at the start of 2025. According to the letter, offshore wagers linked to those fires generated more than $1.2 million in trades.

The immediate issue is not whether a market can forecast fire. It is whether a tradable contract around a public disaster crosses from information-gathering into a public-safety risk.

CFTC review gains new pressure

The request lands while the CFTC is reviewing public input on a proposal that would add guardrails for prediction-market platforms. The agency treats such venues as derivatives exchanges, which gives it a public-interest lens for deciding whether some contracts should be barred.

Prediction markets have broadened well beyond elections and finance-linked events. The supplied source described rapid growth over the past 18 months, with contracts spanning sports, award shows, geopolitics and other outcomes that can attract retail traders.

Wildfires bring a different regulatory problem because the underlying event can be affected by human conduct. A market on a film award does not create the same physical-harm pathway as a market whose payout could rise with acreage burned, property destruction or casualty counts.

Polymarket example raises enforcement questions

Polymarket is central to the senators’ argument because the letter points to offshore trading rather than only US-regulated activity. That creates a harder question for the CFTC: how far domestic public-interest rules can reach when traders can move to venues outside the agency’s direct perimeter.

Another platform named in the source, Wyldfyre, has positioned itself around California wildfire trading. Its website says, “You can’t predict fire, but you can trade on it,” while also stating that the current version uses “play money only” rather than real-money trades.

Those distinctions matter for enforcement. If a platform uses no real money, the incentive risk is lower; if a liquid offshore contract pays in real value, the agency’s concern shifts to access controls, marketing, settlement rules and whether US users can participate.

Fire season sharpens the stakes

The senators’ warning comes as smoke from major Canadian fires has reached dense US population centers and worsened air quality in recent weeks. Merkley’s home state, Oregon, has also faced multiple blazes, with local reporting cited in the source placing burned land at about 1.7 million acres by late July.

For the broader industry, the danger is that wildfire contracts become the test case for limits on event markets more generally. A narrow CFTC action could leave most prediction markets intact while carving out disaster-linked contracts; a broader rule could force platforms to screen contracts for public-harm incentives before listing them.

If the CFTC restricts wildfire markets, the macro effect would probably be indirect: less about fire losses themselves and more about drawing a boundary around financial products tied to real-world harm. Polymarket would face pressure to show tighter controls around sensitive events, while the wider sector would need clearer listing standards.

If the agency takes a lighter approach, liquidity may continue shifting to offshore venues where US regulators have less leverage. That would leave Polymarket and similar platforms with more room to grow, but it would also raise the industry’s exposure to reputational damage if a disaster-linked contract is blamed for encouraging harmful conduct.

The open questions are specific: whether the CFTC defines wildfire contracts as contrary to the public interest, whether offshore access can be limited in practice, and whether play-money platforms remain outside the same risk category. The answers will help decide whether prediction markets expand as regulated information tools or face new lines around catastrophe betting.
