US bank failure by December 31, 2026?
There is already a meaningful pattern of small bank failures in 2026, which keeps a further FDIC-listed failure before year-end firmly plausible. I would put the chance of Yes modestly above the market and around two-thirds.
Analysis
The key question is not whether the U.S. banking system is under broad stress, but whether at least one FDIC-insured bank will be added to the Failed Bank List before December 31, 2026. The recent record strongly supports some residual risk: six banks have reportedly already failed this year, including the latest in late September, and that pace is far above 2025. Even though the institutions involved have been small, repeated closures suggest the system has already produced enough weak balance sheets, liquidity pressure, or supervisory clean-up cases to make another failure before year-end a live possibility rather than a tail event.
At the same time, the evidence does not point to a systemic crisis. The failures so far have been contained in size, with combined assets around $1.45 billion, and the available descriptions emphasize orderly resolutions rather than chaotic collapse. That matters because the market’s Yes outcome does not require a major bank or a crisis, only one more qualifying failure. In that sense, the bar is relatively low, and the historical pattern of bank failures often comes in clusters once a few weak institutions are identified. With more than two months left in the year, the odds of at least one additional small bank being closed remain meaningful even if the broader system stays stable.
The current market price of 59% seems reasonable but slightly conservative given the observed 2026 pace. A neutral reading would note that the most recent failure was in September, so there is no guarantee the pattern continues immediately. However, bank failures are often lumpy and can appear after supervisory actions, acquisition breakdowns, or sudden liquidity deterioration, any of which can emerge late in the year. Because the event only needs one more failure, and because the year has already seen multiple resolutions, I think the probability of a Yes outcome is somewhat above the market-implied level.
Arguments
For
- Arguments for Yes: The 2026 failure count is already materially above last year, which indicates a live pipeline of weak banks.
- Arguments for Yes: A single small-bank failure is enough to satisfy the event, and that remains a realistic possibility before December 31.
Against
- Arguments against Yes: The reported failures have all been small and contained, so the remaining universe of at-risk banks may be limited.
- Arguments against Yes: If supervisory issues do not escalate quickly, the calendar may run out before the next FDIC closing date appears.
Key drivers
- Six FDIC-insured banks have already failed in 2026, showing that the environment has produced multiple closures this year.
- The event only requires one additional bank failure before year-end, which is a relatively low threshold.
- The failures so far have been small and orderly, which suggests ongoing isolated resolutions remain plausible.
- There is enough time left in the year for a late supervisory action or liquidity problem to trigger another closure.
Risk factors
- The 2026 failures may already have exhausted the weak institutions most likely to fail this year.
- A stable macro-financial backdrop in the final months of the year could prevent any further closures.
- The absence of signs of systemic distress lowers the chance of a cascade of failures.
- Resolution timing can slip into 2027 even if a bank is under stress late in December.
Scenarios
Best case
Another weak small bank is closed before year-end, adding to the 2026 tally and triggering a Yes resolution with little broader market impact.
Most likely
The banking sector remains generally stable but still has enough residual weakness for one more small-bank failure to occur before year-end, making Yes slightly more likely than not.
Worst case
No additional bank is placed into FDIC resolution before December 31, and the year ends with the existing failures only, producing a No outcome.

Next Press Secretary announced by...?
AI93%MKT20%Edge+73Hidden GemThe literal wording strongly favors Yes because Katie Zacharia was publicly announced as White House press secretary on October 11, well before the October 31 deadline. The main uncertainty is whether the contract is actually tracking a later replacement announcement rather than the original appointment, but based on the stated rules, Yes is the far likelier outcome.

Oscars 2027: Best Adapted Screenplay Nominations
AI62%MKT89%Edge-27HypedThe Odyssey has a real path to an adapted screenplay nomination, but the screenplay race looks more volatile than the market price implies. I would price it meaningfully below the current market, though still above a coin flip because the film’s overall awards strength should keep it in the conversation.
