Trade: US bank failure by May 31?

Market outcomes
| US bank failure by May 31? | 11% YES | 90% NO |
Market context
The question centres on whether the Federal Deposit Insurance Corporation will add any institution to its Failed Bank List between now and 31 May 2026. The FDIC maintains this official registry of US bank closures, which serves as the definitive settlement source. Currently, Polymarket's order book is pricing this outcome at 11% probability, reflecting trader expectations that the US banking system will remain stable through the settlement window.
Historical context shows US bank failures cluster during periods of systemic stress. Between 2008 and 2012, the FDIC closed 489 banks following the financial crisis; by contrast, the period from 2013 to 2022 saw only 6 closures. The 2023 failures of Silicon Valley Bank, Signature Bank, and First Republic Bank—triggered by deposit flight and interest rate exposure—killed 3 institutions in months, yet the broader system stabilised thereafter. The 11% probability reflects a baseline expectation of stability similar to recent years, though acknowledging non-zero tail risk.
Traders should monitor quarterly stress test results from the Federal Reserve, scheduled for June 2025 and June 2026, which assess large bank resilience. Regional bank deposit flows and commercial real estate valuations warrant attention, given their historical correlation with failure waves. The Federal Reserve's interest rate trajectory remains material; any sharp policy reversal could expose duration mismatches on bank balance sheets. Recent reporting from the Wall Street Journal and regulatory filings will signal emerging vulnerabilities before any formal closure announcement.

How active is this market?
$6K in lifetime turnover and $2K of resting liquidity puts this market in the below the median by volume for business contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $95 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
