Polymarket Bank-Failure Bets Draw Scrutiny From UK Regulators
People on Polymarket are trading contracts about whether some big banks will fail by the end of 2026.
The contracts include HSBC and Lloyds Banking Group.
About $77,500 has been traded in the market.
This does not mean those banks are expected to fail.
Some people worry that someone could spread rumors or try to affect opinions to make money from a bet.
UK and European regulators are looking at risks such as insider trading and market manipulation.
Polymarket says these markets can make information available to more people.
UK rules may restrict some financial prediction products from being sold to retail customers.
Regulators are watching how these markets develop.
A Polymarket market covering possible failures of major banks had about $77,500 in trading volume.
Contracts include HSBC and Lloyds Banking Group, but their existence does not indicate that either bank is expected to fail.

Critics including MP Bobby Dean warn that bets could create incentives to aggravate market sentiment and potentially worsen a bank run.
