Weather prediction market data API

Resolved Markets captures Polymarket's weather markets: daily high-temperature contracts for 51 cities, hurricane and named-storm markets, and longer-horizon climate markets like Arctic ice extent and annual record temperatures. Every snapshot is stored with full bid/ask depth and kept indefinitely. Weather is included on the Scale plan and above.

Why weather prediction-market data matters

Polymarket weather markets are a near-pure source of probabilistic forecasts priced by people with USDC at stake. They sit upstream of three useful signals:

  • Forecast benchmark. Compare GFS / ECMWF / proprietary model outputs against a market that prices the same outcome — the spread is a quick read on model confidence.
  • Energy-trading nowcast. Heat-wave and cold-snap markets move ahead of NWS official advisories during volatile periods. Power and gas desks watch them as a sentiment overlay.
  • Climate research. Long-horizon markets (annual records, Arctic ice) provide forward-looking pricing for climate questions that traditional surveys cannot price discretely.

Frequently asked questions

Which weather markets are covered?

Daily high and low temperature contracts for 51 cities (NYC, Miami, London, Hong Kong, etc.), hurricane / named-storm markets, and longer-horizon climate markets (Arctic ice, annual temperature records). All resolve from official sources (NWS, NOAA).

Why would anyone want weather prediction-market data?

Weather markets are a near-pure source of probabilistic weather forecasts priced by people with skin in the game. Researchers use them to benchmark model forecasts, energy-trading desks watch them around heat waves and cold snaps, and quantitative climate research treats them as forward-looking sentiment data.

Is weather available on the Free tier?

No — Free and Pro are crypto-only. Weather (and sports, economics, social, equities) starts on the Scale tier ($49/mo). The Free tier covers all crypto coins with 300 req/min, unlimited history, and full bid/ask depth.

How frequently are weather markets captured?

Weather markets trade slower than crypto, so capture is typically 0.2–0.5 Hz per token (event-driven, not polled). Every change in the orderbook is captured; idle markets simply produce fewer snapshots.

Do you provide the underlying weather forecasts?

No — Resolved Markets provides only the prediction-market orderbook data. For raw NWS/NOAA forecasts, use those agencies directly. Resolved Markets pairs naturally with forecast feeds for spread analysis.
