UK urged to act as Polymarket takes bets on whether HSBC and Lloyds will fail

The online prediction market Polymarket has come under regulatory scrutiny following reports that users have wagered approximately $77,507 on the potential failure of major financial institutions, including two prominent UK banks. The platform, which permits betting on a wide range of events from sports outcomes to geopolitical developments, has attracted positions on numerous global lenders including HSBC and Lloyds Banking Group.

While the platform restricts users from the UK, US, Canada, and EU through its offshore structure, individuals from approximately 150 other countries remain able to place bets that could financially benefit from banking sector collapse and resulting economic instability. The UK’s Financial Conduct Authority has indicated it is engaging with international regulators to address concerns around prediction markets and market integrity. Lawmakers, including Liberal Democrat MP Bobby Dean, have called for intervention, arguing that uncontrolled betting could potentially trigger bank runs if market activity escalates, particularly given recent precedents of social media-fueled financial instability.

Regulatory bodies have expressed concerns about insider trading and market manipulation on Polymarket. The European Securities and Markets Authority warned in a recent report that prediction markets have become vehicles for illicit activity, citing historical examples including suspicious trading patterns ahead of military operations and alleged misuse of classified information. The platform’s blockchain-based structure and anonymous crypto wallets create challenges for identifying actual account holders and preventing bad-faith actors from exploiting non-public information.

Polymarket’s leadership contends that the platform democratizes access to market information previously available only to institutional traders and that the underlying data regarding bank health is already publicly available. The company argues that prediction markets serve as valuable information sources and can help combat misinformation. However, academics and regulators have cautioned that such platforms create moral hazard by potentially incentivizing participants to engage in illegal or dangerous activities to influence contract outcomes.

Neither HSBC nor Lloyds provided comment on the matter, and the UK Treasury did not respond to requests for clarification on any potential regulatory action.
