Asia Gaming eBrief: Prediction markets face new scrutiny as sports volume grows

Prediction markets have emerged as a significant but largely unregulated channel for sports wagering, particularly during major sporting events. During the 2026 FIFA World Cup, platforms such as Kalshi and Polymarket processed close to $2 billion in sports-related trades, according to analysis by HTX Research. This volume is notable not only for its scale but for the regulatory gap it exposes: these platforms functioned as de facto sportsbooks while sidestepping the licensing, integrity oversight, and consumer protections that traditional bookmakers are required to maintain.

The distinction between prediction markets and regulated sportsbooks is increasingly blurred in practice. Prediction markets operate on the premise that they are financial derivatives or information markets rather than gambling venues, allowing them to claim exemptions from gaming regulation in many jurisdictions. However, when users are trading on the outcome of sporting events with real money at stake, the functional difference from sports betting becomes negligible from a consumer and integrity perspective. The $2 billion World Cup volume demonstrates that this regulatory arbitrage has real commercial significance.

This growth is prompting regulators and sports integrity bodies to reassess their approach. Traditional sportsbooks invest heavily in responsible gambling measures, fraud detection, and anti-match-fixing protocols. Prediction markets, by contrast, often operate with minimal such infrastructure. The integrity risks are substantial: unmonitored, high-volume trading on sports outcomes creates potential vulnerabilities to manipulation and insider trading. Additionally, consumers using these platforms may lack the protections available on licensed sportsbooks, including deposit limits, self-exclusion tools, and dispute resolution mechanisms.

The scrutiny facing prediction markets reflects a broader regulatory trend toward closing loopholes in online gaming oversight. Jurisdictions are increasingly questioning whether the functional equivalence of an activity to gambling should trigger gaming regulation, regardless of the platform's technical classification. Asia-Pacific regulators, in particular, have shown willingness to take aggressive stances on unlicensed gaming channels.

For operators and platforms, the trajectory suggests that prediction markets will face mounting pressure to either obtain sports betting licenses or implement compliance measures comparable to regulated sportsbooks. The $2 billion World Cup volume may ultimately accelerate regulatory action, as governments recognise both the consumer protection gaps and the tax revenue implications of unregulated sports trading.
