62% — Will the number of distinct government shutdowns (as defined in the GOVTSHUTLENGTH contract, with shutdown status checked at 10:00 AM ET each day) be exactly 5 in 2026

Tracks the leading outcome in a winner-take-all prediction market set with 2 outcomes.

Why this matters:
This contract asks whether the U.S. government will experience exactly 5 distinct shutdowns during 2026, with each shutdown defined by a daily status check at 10:00 AM ET. The 3% probability reflects market skepticism that five separate shutdown events will occur this year; markets currently assign highest probability (62%) to exactly 2 shutdowns instead. The probability hinges on Congressional budget negotiations and debt-ceiling deadlines throughout 2026. Key drivers include the frequency of funding lapses, how quickly shutdowns are resolved, and whether political gridlock intensifies or moderates. The primary resolution catalyst is the end of 2026, though mid-year spending bills and debt-ceiling votes in spring and fall will signal whether multiple shutdowns are accumulating on track. Current market pricing suggests traders view exactly 5 shutdowns as an extreme outlier scenario, substantially less likely than outcomes with 2–3 shutdowns.

Key factors:
- As of September 2026, if fewer than 3 shutdowns have occurred year-to-date, reaching exactly 5 total becomes mathematically compressed into remaining months and less probable
- Congress must pass multiple continuing resolutions or full budget bills; failure at each major deadline creates a shutdown opportunity, making frequency dependent on legislative calendar deadliness
- Historical baseline: recent years (2018–2023) averaged 0–2 shutdowns annually, suggesting 5 is materially above historical norms under typical political conditions
- Resolution depends on the strict definition in GOVTSHUTLENGTH contract—shutdown status checked daily at 10:00 AM ET means timing and duration of any lapse matter for counting as a distinct event
- Market concentration on exactly 2 shutdowns (62%) and exactly 3 (23%) indicates consensus that 5 falls into tail-risk territory, requiring sustained political dysfunction or unusual legislative behavior

Contracts:
- Will the number of distinct government shutdowns (as defined in the GOVTSHUTLENGTH contract, with shutdown status checked at 10:00 AM ET each day) be exactly 2 in 2026?: 2 — 62¢ Kalshi $0 (weight 0%)
- Will the number of distinct government shutdowns (as defined in the GOVTSHUTLENGTH contract, with shutdown status checked at 10:00 AM ET each day) be exactly 3 in 2026?: 3 — 25¢ Kalshi $1 (weight 100%)

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
