Polymarket Temperature Threshold Markets Guide

Temperature markets are measurement markets. They are not about whether a city feels hot. They depend on the stated location, station/source, unit, date, and whether the rule uses daily high, observed high, forecast, or another measurement.

This page is educational research content. It explains market structure, source discipline, probability notes, and review workflows. It does not tell you what to trade.

Key concepts in plain English

• ▸Market title: the short headline. Useful, but never enough by itself.
• ▸Rules: the settlement contract. This is where definitions, deadlines, and source standards live.
• ▸Displayed probability: the market's current Yes/No pricing expressed as a percentage-style snapshot.
• ▸Spread and depth: the difference between executable interest on each side and the size available near the displayed price.
• ▸Source hierarchy: the ranked list of official sources, market rules, and evidence you will use after the event.

What this market type means

A temperature threshold market asks whether an official or specified source records a temperature at, above, below, or exactly around a stated level for a place and date.

Gamma active-market samples reviewed July 12, 2026 PDT included city high-temperature markets for Wuhan and Taipei with stated Celsius thresholds and dates. That sample is inspiration for research workflow, not a suggestion about a side.

The research workflow

Start with the market rules. Copy the question, the accepted source, the date, the timezone if listed, and the exact words that define the result. Then write a one-sentence trigger: "This market resolves Yes if..." If you cannot write that sentence without guessing, the market is not ready for a serious note.

Next, save the market state. Record Yes price, No price, spread, depth, volume, end date, and the timestamp of your note. Prices can move faster than your reasoning. A timestamp makes later review honest.

Finally, build the evidence file before the event ends. Add official links, known reporting sources, and any rule text that might become disputed. The goal is not to predict louder. The goal is to know exactly what evidence would settle the question.

Probability math without overclaiming

A market can show a price close to 0.1% or 99.9% near resolution, but the final question is still measurement and source. The last few basis points can represent station risk, data update risk, or settlement uncertainty rather than a broad climate forecast.

The clean habit is to write: displayed probability, spread, depth, source risk, and deadline risk as separate fields. A single number is not a complete research note.

Common mistakes

• ▸Using a weather app that is not the market source.
• ▸Missing Celsius versus Fahrenheit or above-versus-at-least wording.
• ▸Ignoring station location inside a broad city name.
• ▸Forgetting that late-day updates and source revisions can matter.

Practical checklist

• ▸Copy the city, date, unit, threshold, and source.
• ▸Confirm whether the market says above, at least, below, exact, daily high, or observed high.
• ▸Save source screenshots or links with timestamps for research notes.
• ▸Check the market close time and local timezone.
• ▸Record spread and depth, especially near resolution.
• ▸Review whether the final source matched your assumptions.

Sources and last-verified notes

Last verified: 2026-07-12 PDT.

Sources reviewed: The weather source named in the specific Polymarket market rules, official meteorological observations when cited, and Polymarket docs for market and data structure. Polymarket public Gamma API active-market samples checked with a browser user agent on July 12, 2026 PDT; Polymarket docs llms.txt and llms-full.txt reviewed for event/market structure, public market-data APIs, CLOB context, resolution/data fields, and referral-code API context. No newer official affiliate term sheet was independently located in this run, so the BUCKO offer copy remains scoped to eligible US app users.
