How this service works
Live probability: Who controls the House after the next election? — Stable evergreen URL for a recurring question: Who controls the House after the next election? Auto-resolves to the current market instance and rolls forward on resolution, so the answer is always about the next occurrence. Response adds current_slug and rolls_to_next_at to the standard probability shape.
Output
Returns a normalized probability (0–1) for House control aggregated across Kalshi and Polymarket, per-venue implied probabilities with 24h volume and liquidity scores, divergence between venues, 1-hour price move, resolution date, resolution criteria summary, the current active market slug, and the timestamp at which this evergreen URL will roll forward to the next election instance.
Example use cases
Political dashboard live odds widget
“Show me the latest prediction market probability for House control in the next election, including how Kalshi and Polymarket differ and how much it's moved in the last hour.”
Election night probability monitoring
“What's the current aggregate probability for who controls the House, and when does this market roll over to the next election cycle?”
Policy research briefing prep
“I need the live odds from prediction markets on House control for my policy brief — give me the current probability, the resolution criteria summary, and the per-venue breakdown between Kalshi and Polymarket.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/house-control-next-electionWhen to prefer
Choose this endpoint when you need a stable, evergreen URL that always points to the next House election probability without tracking slug changes yourself. Prefer it over building your own Kalshi/Polymarket aggregation when you want cross-venue divergence signals and automatic market rollover. Ideal for dashboards, newsletters, or agents that need a single consistent URL for recurring election coverage.
Side effects
- No active market found: may return null or empty data if no current House control market is live on either venue
- Stale data: if upstream prediction market APIs are delayed, probability and last_move_1h may lag real-time
- Payment failure: $0.02 USDC x402 payment not processed results in 402 response
- High divergence: per-venue implied_p values may differ significantly, requiring manual interpretation
