SKN | UK FCA Reconsiders Prediction Market Ban as Kalshi and Polymarket Gain Global Traction

Key Takeaways

• The UK Financial Conduct Authority is reportedly exploring whether to ease its seven-year prohibition on retail access to financial prediction markets.
• The review comes as global prediction-market activity expands rapidly, with industry forecasts putting 2026 trading volume at approximately $240 billion.
• A UK regulatory opening could bring event-based derivatives into a supervised framework, but consumer protection, gambling rules and product classification remain significant hurdles.

The UK financial regulator is considering whether its long-standing restriction on retail prediction markets should be eased, potentially opening the door to platforms such as Kalshi and Polymarket. The development comes as prediction markets move closer to mainstream financial infrastructure, increasingly overlapping with derivatives, crypto markets and traditional event-driven trading.

Seven-Year Ban Faces a New Test

The FCA prohibited firms from selling, marketing or distributing binary options to retail consumers in 2019, citing the potential for significant losses and concerns that consumers might not understand the risks involved. Financial prediction markets offering contracts on whether specific events will occur have generally fallen within that framework.

The regulator’s reported discussions with prediction-market operators suggest that the economics of the market may now be forcing a reassessment. Millions of UK consumers are reportedly accessing overseas platforms despite domestic restrictions, creating a regulatory dilemma: maintaining the prohibition may reduce direct consumer exposure to regulated firms while pushing activity toward offshore venues with fewer UK protections.

The FCA has not formally lifted the ban. Its current regulatory position continues to treat financial prediction-market products as binary options, while non-financial markets such as sports and political contracts can also fall within the UK’s gambling regulatory framework.

Prediction Markets Are Becoming a Major Derivatives Category

The scale of the international market helps explain why the issue has become more difficult to ignore. Global prediction-market trading is projected to reach approximately $240 billion in 2026, compared with around $51 billion in 2025.

Kalshi has also expanded well beyond traditional political and economic event contracts. Its perpetual-futures business generated approximately $13.7 billion in trading volume during August, almost twice July’s level, demonstrating how quickly prediction-market infrastructure is moving toward conventional derivatives.

That expansion is particularly relevant to crypto investors. Bitcoin and other digital assets are increasingly represented through event contracts and perpetual products, creating a hybrid market in which users can obtain market exposure through structures that sit between conventional derivatives and event-based trading.

UK Opening Could Reshape Market Competition

If the FCA ultimately permits some form of retail access, the impact would extend beyond UK consumers. A regulated British framework could provide prediction-market operators with access to one of the world’s largest financial centers while establishing clearer requirements for disclosure, market surveillance, leverage and consumer protection.

However, regulatory approval would not automatically create a unified market. Political and sports contracts could still require separate gambling authorization, while financial contracts would remain subject to financial-services rules. The distinction could determine which products operators are able to offer and how they structure their UK businesses.

For investors, the UK’s approach could also become a reference point for other jurisdictions assessing whether prediction markets should be treated primarily as gambling products, financial derivatives or a separate category.

Regulatory Clarity Becomes the Next Catalyst

The FCA’s reported review does not guarantee that the 2019 restrictions will be removed, but it signals that the rapid growth of prediction markets is forcing regulators to reconsider whether prohibition remains effective. For professional crypto and derivatives participants, the central question is increasingly where these markets should sit within the financial system.

A controlled UK reopening could strengthen institutional legitimacy and bring more activity into regulated venues. Conversely, stricter rules could preserve the existing divide between domestic regulation and offshore market demand. The eventual decision will help determine whether prediction markets become an established component of regulated financial markets or remain a largely parallel trading ecosystem.
