Analysis

This 38% probability reflects market belief that SpaceX's Starship will complete a launch from Florida within the next 14 months. The market is pricing in meaningful uncertainty despite SpaceX's track record and Florida facility readiness. Launch timing depends on regulatory approvals, technical readiness following recent test flights, and maintenance schedules. The next scheduled Starship test flight will provide direct evidence of progress and could shift probabilities materially. Near-term factors include FAA licensing decisions and whether SpaceX maintains its operational cadence through summer 2026.

  • SpaceX's most recent Starship test flight results and any damage assessment affecting launch readiness
  • FAA approval status and any new environmental or safety conditions imposed on Florida launches
  • Technical modifications required after previous test flights and publicly announced timelines for completion
  • Competition and congestion at Florida launch facilities affecting scheduling
  • Regulatory or weather delays historically seen in Starship's launch history

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (36% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

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.
