Analysis

This probability estimates the likelihood that at least one major bank will fail by December 31, 2026. The 8% level reflects relatively low near-term systemic risk, though higher than 2024-2025 baseline expectations. Markets are pricing in moderate concern around interest-rate volatility, deposit stability, and asset quality deterioration as key drivers. Investor attention centers on Truist (priced at 28¢ across contracts), suggesting concentrated concern about a specific institution rather than broad-based banking sector collapse. The resolution hinges on official regulatory determinations or formal FDIC intervention by year-end. Key uncertainty factors include Q2-Q3 2026 earnings seasons, which will reveal loan loss provisions and net interest margin pressure, and any macroeconomic shocks affecting credit quality or liquidity conditions.

  • Truist commands 28¢ pricing versus 3-5¢ for other major banks, indicating market focus on a single institution rather than systemic risk
  • Interest-rate environment through mid-2026 will materially affect net interest margins and deposit flight risk for regional and mid-cap banks
  • Corporate and commercial real estate loan performance data in Q2-Q3 2026 earnings will signal asset-quality deterioration or stability
  • Regulatory capital ratios and stress-test results (if conducted) provide objective thresholds for intervention decisions
  • No scheduled major regulatory event or stress test is formally planned for 2026, making resolution dependent on deterioration triggers rather than scheduled reviews

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
