US prediction markets grow amid calls for support on gambling

The rapid expansion of prediction markets in the United States has alarmed public health advocates, who are urging for more solid support systems to address gambling-related issues. Platforms like Kalshi and Polymarket have gained traction, especially in regions lacking sufficient resources for individuals facing gambling problems. According to The Guardian on 21 June 2026, this trend could aggravate existing public health challenges.

Prediction markets have traditionally been a niche within the wider online gambling sector, allowing users to trade based on event outcomes. The emergence of these markets in the US coincides with increasing state-level legalisation and a growing interest in online betting. Though these platforms often portray themselves as financial tools rather than gambling services, the distinction can be ambiguous, potentially inviting regulatory examination. The UKGC, for instance, has consistently enforced stringent oversight of gambling operators to ensure consumer protection, a standard that might influence US regulatory developments as this sector grows.

"A UKGC spokesperson stated on 22 June 2026: 'Our focus is on consumer protection and responsible gambling, which remain central to our regulatory framework.'"

Implications for UK casino players

For UK casino players, the rise of US prediction markets may seem remote, yet it shows the necessity of maintaining solid regulatory practices at home. The UKGC's dedication to consumer protection ensures that gambling platforms under its jurisdiction comply with strict standards. Players using platforms like Bet365 or Sky Vegas can trust in the safeguards protecting their interests. Staying informed about regulatory changes abroad is crucial, as they may eventually impact domestic policies or market trends.

Contextualising the scale

While the expansion of US prediction markets raises concerns, it's vital to contextualise their scale. The £273,000 penalty imposed on some operators within the UK is notable but ranks fourth among the financial penalties issued by the UKGC this year. As of our 22 June 2026 audit, 26 penalties have been issued, totalling £19 million, with three major settlements comprising the bulk of this amount. This context illustrates the continuous regulatory vigilance present in the UK, contrasting with the developing regulatory frameworks in the US.
