Analysis

This market estimates the probability that exactly 2 federal government shutdowns will occur during 2026, with the probability currently at 61% based on pricing from prediction markets. Government shutdowns happen when Congress fails to pass appropriations legislation by the deadline, typically September 30th annually. The current high probability for exactly 2 shutdowns reflects expectations that fiscal negotiations will be contentious but ultimately result in a limited number of disruptions. Upward pressure on this probability comes from historical patterns of repeated shutdown threats and short-term continuing resolutions, while downward pressure would emerge from either unified fiscal action or extended political deadlock. The key catalyst will be September 30, 2026, when the current fiscal year appropriations expire, followed by any subsequent deadline expirations. Current market pricing suggests multiple shutdowns are expected but concentrated disruption is anticipated.

  • Historical frequency: The U.S. experienced 4 shutdowns between 2013-2019, establishing a baseline for how often fiscal deadlines produce actual shutdowns rather than last-minute resolutions
  • Congressional composition and party control: The political alignment and negotiating dynamics in 2026 will determine whether appropriations pass routinely or face repeated temporary funding gaps
  • September 30, 2026 deadline: The primary annual appropriations expiration date serves as the first major trigger point; how this negotiation resolves will inform expectations for subsequent deadlines
  • Continuing resolution patterns: Markets appear to price in some combination of short-term CRs and actual shutdowns rather than comprehensive year-long appropriations, suggesting fiscal uncertainty persists
  • Runner-up probability at 19%: The second-most likely outcome (different shutdown count) indicates material uncertainty exists despite the 61% leader, suggesting prediction markets view multiple scenarios as plausible

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.
