MP warns Polymarket bank bets could trigger real bank runs
An MP on the Treasury Committee warns Polymarket’s bank-collapse markets could help cause the panic they bet on.
The hit
Polymarket is letting users bet on whether major banks will collapse before the end of 2026, & UK lawmaker Bobby Dean warns the activity itself could help trigger a bank run. More than $77,000 has been traded on the market, according to The Guardian. HSBC, Lloyds, JPMorgan Chase, BNP Paribas, Bank of America & Goldman Sachs all feature.
Why it matters
Banks run on confidence, not just balance sheets. A fast-moving public market tracking failure odds could spook depositors the same way social media accelerated withdrawals during the 2023 collapse of Silicon Valley Bank. Polymarket says its markets make information already available to professional investors more accessible to the public. Banks & hedge funds have long traded credit default swaps on similar logic, the article notes.
The record
| Banks listed as possible failures | HSBC, Lloyds, JPMorgan Chase, BNP Paribas, Bank of America, Goldman Sachs |
|---|---|
| Failure probability on Polymarket | Low single digits for HSBC & Lloyds |
| UK binary options ban cited by FCA | In force since 2019 |
What happens next
The FCA says it is discussing prediction markets with overseas regulators, & the Bank of England is monitoring developments, according to The Guardian.
