UK authorities examine bets on HSBC and Lloyds failing amid manipulation fears
US-based prediction market Polymarket has begun accepting bets worth $77,507 on whether major banks, including UK lenders HSBC and Lloyds, will fail by the end of the year. The revelation has triggered alarm from UK authorities and lawmakers who fear the betting mechanism could incentivise market manipulation, insider trading, and trigger the kind of rapid bank runs that brought down Silicon Valley Bank and Credit Suisse in 2023.
The FCA has begun discussions with international regulators about prediction markets' impact on financial system integrity. Democratic MP Bobby Dean has called for UK authorities to contact US counterparts, warning that rapid growth in bank-related betting could exploit shifts in market sentiment. Polymarket's leadership argues the bets democratise access to financial information previously available only to institutional traders, whilst academics and European regulators counter that such platforms create "moral hazard" and are vulnerable to insider trading abuse.
