Analysis
This contract resolves to YES if Congress passes and the President signs legislation authorizing a Women's History Museum on the National Mall before year-end 2026. The 42% probability reflects modest but not negligible chances, suggesting meaningful legislative interest but substantial hurdles remain. The core drivers are current congressional appetite for cultural and historical funding initiatives, and the procedural difficulty of securing floor time and bipartisan support within a six-month window. The single biggest catalyst is the outcome of congressional scheduling decisions in July–September 2026, when leaders typically finalize their legislative calendars for the final quarter. Bills advancing through committee or receiving explicit leadership commitment would shift probabilities materially upward; conversely, competing infrastructure or appropriations priorities could displace this initiative from the agenda entirely.
- ›Congressional committees must vote the bill out of committee and leadership must allocate scarce floor time before January 1, 2027—fewer than 155 legislative days remain
- ›The bill requires presidential signature; unified control of Congress and the White House increases passage likelihood compared to divided government scenarios
- ›Museum authorization bills historically achieve lower pass rates than infrastructure or appropriations legislation, despite bipartisan cultural support
- ›Competing legislative priorities (surface transportation reauthorization, railway safety, appropriations deadlines) compete for the same finite legislative capacity in 2026
- ›Recent congressional activity and committee scheduling in June–July 2026 will signal whether this proposal has serious sponsor momentum or remains aspirational

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.
