Analysis

This probability indicates a 57% chance that Graham Platner, a candidate in Maine's 2026 Senate election, will withdraw from the race before July 9, 2026—approximately 48 hours from now. The high probability reflects near-term resolution, with contract prices showing elevated expectations of withdrawal on very specific dates. Factors driving this include recent campaign developments, polling performance, or candidate circumstances that have triggered speculation about an imminent exit. The market appears to price in substantial uncertainty compressed into days rather than weeks, suggesting either recent news or an anticipated announcement. The resolution hinges on whether Platner formally announces a dropout or files withdrawal paperwork before the July 9 deadline. After July 9, the market will simply resolve to either yes or no based on documented withdrawal status, eliminating the current speculation around the precise timing of his decision.

  • Market prices for earlier deadlines (72¢ for Jul 9) suggest meaningful probability of withdrawal within 48 hours rather than speculation about eventual exit
  • Contract pricing shows progressive increases for later deadlines (91¢ for Jul 14), indicating traders expect clarity by mid-July if not immediately
  • High trading volume in the Jul 14 contract ($2.1M in 24h) indicates significant market attention to this specific candidate race
  • If no withdrawal occurs by July 9, the market will immediately reprice based on new timeframe expectations
  • Platner's current campaign status, recent statements, and any disclosed health, family, or personal circumstances directly determine whether withdrawal is imminent or speculative

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.
