The market resolved this question before the thermometer did. Taipei’s highest temperature on July 1 closing at 36°C carries a 99.6% implied probability, and the price action tells the real story: this contract opened the day at 0.26 and rocketed to 1.00 on confirmed meteorological data. The 24-hour price jump of 60% is not speculation. That is a market absorbing real-world measurement and repricing instantly.

The market question asks: what is the highest temperature in Taipei on July 1? The 36°C outcome is priced at 1.00, with the NO side at 0.00. The contract closes at 2026-07-01 12:00. Total volume stands at $177,672, with $153,040 of that trading in the last 24 hours alone. This market moved fast and hard on verified data.

How the Thirty-Six Degree Contract Works

This contract resolves YES if Taipei’s highest recorded temperature on July 1, 2026 hits exactly 36°C, as confirmed by the market’s designated resolution source. All other temperature outcomes, including 35°C, 37°C, 38°C, 39°C or higher, and every bin below 35°C, resolve NO for this specific outcome. The contract closes at noon local time on July 1.

  • YES (36°C): priced at 1.00, implying a 99.6% probability that this bin captures the day’s peak.
  • NO (all other bins): priced at 0.00, implying a 0.4% combined probability that any other outcome resolves.

For NO to pay out, Taipei’s peak would need to land in any bin other than 36°C. That means the official reading would need to reach 37°C or higher, or fall to 35°C or below. Given that the 36°C bin is now priced as a near-certainty, the market is saying the temperature data already confirms this outcome. The 0.4% residual is pure settlement and timing noise.

Momentum and Market Signals

The momentum composite here is unambiguous. A 60% price surge in 24 hours, paired with a trend score of 64.07 and a flat 1-hour change, signals that the market absorbed new information rapidly and then stabilized. The driver is almost certainly confirmed weather station data from Taipei showing the peak reading landed at 36°C. Once real-world data enters a binary temperature market, price discovery ends.

Total volume of $177,672 with $153,040 trading in 24 hours confirms that traders acted on the data in volume. Liquidity sits at $64,231. This is below the $1M threshold for high-confidence market depth, meaning the price could technically shift on a single large order. In practice, at a price of 1.00, there is nowhere for it to go. The thin liquidity is irrelevant here.

  • The 60% single-day price move connects directly to real-time temperature confirmation from Taipei stations, not speculation.
  • The 1-hour price change of 0.0% shows the market found its ceiling and stopped. Price discovery is complete.
  • Trader sentiment runs 99.6% YES against 0.4% NO, the most lopsided reading a binary market can show.
  • The 24-hour volume of $153,040 out of $177,672 total shows this market was nearly dormant, then exploded on confirmed data.
  • Open interest at $0 signals positions are already settled or closing, consistent with a resolved or near-resolved outcome.

Lines Analysis: Taipei Temperature on July First

The meteorological case for 36°C is straightforward. Taipei in early July sits in peak summer heat. The city regularly records daily highs between 34°C and 38°C during this period, with 36°C sitting squarely in the climatological center of that range. The price action, specifically the surge on June 30 and the confirmation run on July 1, tracks the pattern of a market receiving official or semi-official temperature data and converging on the correct bin. Here’s what the measurements are telling us: the thermometer landed exactly where the market now says it did.

For a meaningful NO scenario, the official reading would need to differ from what pushed this price to 1.00. That could happen through a data correction, a dispute over which station constitutes the official Taipei reading, or a late revision pushing the peak to 37°C. None of these are plausible at the 0.4% level, but they are the only paths. The market is pricing uncertainty, not science, and right now it sees almost none.

  • Any official correction from Taipei’s Central Weather Administration pushing the reading to 37°C or above would be the only data event capable of moving this price.
  • A downward revision to 35°C or below would require an unusually cold air intrusion that contradicts already-published station data.
  • Resolution source confirmation in the next few hours will lock this outcome permanently.
  • Related markets show no correlated heat event signals that would suggest an anomalous reading in either direction.

Total volume of $177,672 confirms genuine trader conviction, not a thin market making noise. The data favors the 36°C outcome conclusively. The 0.4% NO price reflects settlement mechanics, not real scientific doubt. The data doesn’t care about the politics, and in this case, it doesn’t leave much room for the market to care about uncertainty either.

LINES VERDICT

CONFIRMED: THIRTY-SIX DEGREES

The Taipei July 1 temperature market has already priced the outcome as settled. The 60-point price surge on confirmed station data, combined with a 99.6% implied probability and near-zero open interest, marks this as a market that has done its job.

What the market says: At 99.6% implied probability, the market treats 36°C as the resolved outcome. The contract closes at noon on July 1, and with open interest at zero, volatility from here is essentially mechanical.

Key unknown: The single event that would reprice this contract is an official data revision from Taipei’s weather authority shifting the peak reading to a different temperature bin before final resolution at noon.

Frequently Asked Questions

It means traders are pricing an approximately one-in-250 chance that the official Taipei peak on July 1 lands outside the 36°C bin. The market has essentially resolved on confirmed data.

An official data revision from Taipei's weather authority would need to shift the recorded peak to any bin other than 36°C, either 35°C or below, or 37°C or higher.

Real-time or near-real-time station data from Taipei showing the July 1 peak at 36°C caused traders to reprice from 0.26 to 1.00 rapidly as the measurement was confirmed.

The contract closes at 2026-07-01 12:00:00 local time. With open interest at zero, most positions appear already settled or in the process of closing.

Volume is below the $1M high-confidence threshold, but at a price of 1.00 with 99.6% probability, the directional signal is clear. Thin liquidity matters more in contested markets than in near-resolved ones.

We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market. It refreshes every hour. The percentage shows how many of those whales hold YES versus NO; the net dollar position shows the cohort's directional exposure in dollars.

A convergence event fires when three or more tracked wallets buy the same outcome on the same market within a four-hour window. We surface these in the activity feed and the VIP digest.

What Could Shift These Probabilities?

Data Confirmation Holds

Taipei's Central Weather Administration publishes final July 1 station data confirming the peak at 36°C. The contract resolves YES at noon and all YES holders receive full payout. No further price movement is possible once the resolution source locks the reading. This is the 99.6% scenario the market has already priced.

Official Data Revision Downward

A post-publication correction from Taipei's weather authority shifts the official peak to 35°C or below before noon resolution. This scenario would reprice the 36°C bin to zero and shift probability to the 35°C outcome. Historical data corrections of this magnitude are extremely rare but technically possible within the resolution window.

Peak Revised Upward to Thirty-Seven

If afternoon heating pushes the official station reading to 37°C before the noon cutoff, the 37°C bin captures the outcome instead. This would require the measurement window to still be open and a late-day temperature spike. Given the noon close, the window for upward revision is narrow but not zero.

Resolution Source Dispute

The designated resolution source and Taipei's Central Weather Administration report conflicting peak readings for July 1. A dispute over which station or dataset governs final settlement could delay or complicate resolution. Prediction markets with ambiguous resolution criteria occasionally reprice sharply on procedural uncertainty, even when the underlying science is clear.

Key macro factor: Taipei sits in a well-documented summer heat corridor influenced by western Pacific subtropical ridge patterns. July 2026 follows a period of elevated regional temperatures consistent with ongoing warm sea surface conditions in the surrounding ocean.
