Analysis

This contract reflects a 40% market estimate that Waymo will launch commercial ride-hailing operations in Washington, DC by December 31, 2026. The probability is notably lower than Tampa (74%) and San Diego (60%), suggesting traders view DC as a less-likely near-term expansion target. Key drivers include Waymo's current operational footprint, local regulatory environment, and internal deployment priorities. The main catalyst will be any official announcement from Waymo regarding DC service launch or explicit timeline guidance. If Waymo confirms DC expansion before mid-2026, the probability would likely increase; conversely, public statements about prioritizing other cities or regulatory delays would pressure it lower. With roughly seven months remaining until resolution, the contract primarily prices in uncertainty about both Waymo's expansion strategy and DC-specific permitting timelines.

  • Waymo's stated operational cities as of May 2026 and any public roadmap mentioning DC within the next six months
  • Regulatory status in DC: whether the city has approved autonomous ride-hailing permits and what conditions Waymo must satisfy to operate
  • Relative ranking of DC in Waymo's expansion priorities compared to Tampa, San Diego, Seattle, and Denver based on investor calls or company statements
  • Historical speed of Waymo's city-by-city rollout: how long between announcement and actual revenue operations in previous markets
  • Any licensing or safety certification requirements specific to DC that differ from states where Waymo currently operates

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.
