Polymarket, Balogun, and the New Corruption Problem No Regulator Can Explain 

To recap, the group from Copenhagen investigating the phenomena occurring on Polymarket during the 2026 World Cup highlighted an important distinction: namely that the Spain-Cape Verde wager was easily legible as anomalous and deserved scrutiny, whereas the Balogun market was not. Their analysis was compelling, but their conclusion came to the forefront of attention and debate for all the wrong reasons. 

By, in effect, misnaming this new category of trade, as I show below, the sports data and prediction market industries have dangerously underestimated how this anomalous trading is impacting their overall integrity; the natural tendency will thus be to over-correct, with potentially catastrophic consequences. In this essay I will argue why creating liquidity for speculative trading on governance-based outcomes – rather than results of sporting fixtures or at-the-door pricing – poses the primary danger.

Beyond Match-Fixing: Trading Governance Instead of Outcomes

Since antiquity, most of the work done around sports integrity has been around anomalous money following influencing a sporting result. This definition neatly encompasses traditional match-fixing, but – importantly – also all of the advances made into understanding links between trading and match integrity over the past thirty years. In the case of the Balogun market, however, anomalous money was not betting on the result of a match; it was betting on a specific governance decision – namely, FIFA's reversal of a suspension. 

Categorising this form of political insider trading as analogous to match fixing leads one to inefficiently apply remedial actions aimed solely at the match-fixing process, despite the role played by prediction markets in documenting – through analyses of price-action – what had taken place. In the Folarin Balogun incident, in real-time, prediction market data outperformed the issuing press statements, and proved more intelligent than FIFA's governance system itself.

Permissionless Creation instead of Watchful Trading

Current surveillance systems are erroneously focused on watching what people bet, rather than watching what markets get created in the first place. In the case of the Balogun market, the real suspicious act was the fact that such a specific market had been created in the first place. The fact that a disproportionate volume of individual bets is being made against it only compounds the concern. 

The reason why such alarming trades are possible at all is because prediction markets lack control mechanisms around the creation of hyper-specific contracts. As such, prediction markets can make money for entities that monetise private conversations between heads of state or sporting officials. Industry pride in permissionless creation makes it inevitably a permanent surface for corruption, because there are no controls over who gets to create markets tied to live disciplinary events.

The Legal Peril of the Gambling Narrative

The ultimate weapon in the prediction market industry's armoury is also its primary weakness: by interpreting prediction markets as sophisticated financial instruments rather than gambling, it can rely on the principle of federal preemption. Unfortunately, the events surrounding the 2026 World Cup provide state attorneys general with powerful political ammunition in their ongoing battle against the gambling narrative. 

Allegations of political interference in sports markets threaten the credibility of prediction markets as sophisticated and legitimate financial instruments, and call into question the consequences of federal preemption. This strikes at the heart of the industry's legal armoury: ironically, prediction markets currently pair adult legal arguments with startup-level infrastructure regarding compliance and integrity. The publication of the Group of Copenhagen report at this volatile time makes for extremely catastrophic timing, as a number of state-level banning measures are currently making their way through judicial systems.

Final thoughts

The immediate importance of this moment should not be understated. Prediction markets must now build an integrity layer around the permissionless creation of markets in order to survive the wave of state-level regulation that will follow. Prediction markets must choose between two stark possibilities: either self-regulating markets for specific contingencies by developing a robust, defined taxonomy of the new breed of corruption to which prediction markets are susceptible, including provenance in market creation, or watch regulators blindly impose rigid bans that are exceedingly difficult to undo. 

• Future World Cups will keep throwing the Balogun incident at regulators as a gift, and the prediction market industry's survival will solely depend on whether it can build the infrastructure to police its own revolutionary inventions.
