Congressional pressure on the industry broadened this week as Sen. Richard Blumenthal and Rep. Paul Tonko launched a public campaign for federal gambling-reform standards covering prediction-market operators, adding to the string of hearing requests and subpoena demands aimed at the industry earlier in September. Separately, new survey data found more than a third of sportsbook bettors are already shifting activity to prediction markets, an early sign that the competitive threat gaming operators have been warning state regulators about is showing up in consumer behavior rather than just industry projections.

Blumenthal and Tonko launch 'Truth and Integrity' campaign for federal prediction-market standards
Sen. Richard Blumenthal (D-CT) and Rep. Paul Tonko (D-NY) joined the Public Health Advocacy Institute and Families and Friends of Gamblers in Washington on September 23 to launch "Truth and Integrity: The Movement for Gambling Reform," calling for congressional hearings, federal minimum safety standards, and stronger state enforcement against prediction-market operators. The lawmakers used the event to promote Blumenthal's previously introduced Prediction Markets Security and Integrity Act, which would impose federal insider-trading and manipulation rules, bar contracts tied to war, death, or military operations, require age verification and self-exclusion protections, and reverse the CFTC's preemption of state gambling law. Blumenthal said prediction markets "are relentlessly and tirelessly taking advantage of vulnerability to simply make more money"; the American Gaming Association and the prediction-market industry oppose federal intervention, arguing state protections are already adequate.

Survey finds over a third of sportsbook bettors are shifting activity to prediction markets
A Fullstory behavioral-data survey of more than 1,000 US consumers, published September 25, found 35% of bettors report using sportsbooks less because of prediction markets, with 60% saying the platforms have changed their wagering frequency overall. Respondents ranked trust and reputation (60%) and ease of use (59%) above odds or payouts (51%) as the main reason for choosing a platform. Economist Victor Matheson separately estimates the prediction-market economy at $50 billion to $100 billion a year in activity that falls outside state gaming-tax bases because the platforms operate under CFTC commodity oversight rather than state gaming licenses, a gap Illinois, Nevada, New Jersey, and Maryland are already contesting in court.
