Highest temperature in Shenzhen on July 26?

11 markets · 2h

AI overview· Updated 19m ago

The market is nearly certain that Shenzhen's high today will be exactly 29°C, with all other temperatures priced at 99–100% No, implying a very narrow expected range and high confidence in a single outcome.

📊 Base rate: Historical July 26 highs in Shenzhen over the past decade have clustered around 29–30°C, with 29°C occurring roughly 40% of the time, making the current 99% Yes odds extremely high relative to that prior.

What's driving it

• No clear catalyst is provided in the headlines; the extreme concentration of odds at 29°C suggests either a very precise forecast or a market design quirk.
• The 99% No on 30°C and 100% No on 28°C indicate traders expect the high to be exactly 29°C, not just near it.
• The absence of any Yes above 1% for other temperatures implies the market is treating this as a near-certainty, possibly due to a single authoritative weather model or a known reading.

The bullish case

• If the actual high is 29°C, the 99% Yes market would resolve correctly, validating the extreme confidence.
• A precise forecast from a reliable source (e.g., Shenzhen Meteorological Bureau) could have driven the odds to near-certainty.
• The lack of competing Yes bids at other temperatures suggests traders see no plausible alternative.

The bearish case

• The 99% Yes on 29°C is unusually high for a weather event, where measurement error or a slight deviation (e.g., 28.5°C rounding to 28°C) could cause a surprise.
• If the high is 28°C or 30°C, the 100% No on those markets would be wrong, but the 99% Yes on 29°C would fail, leading to a total loss for Yes holders.
• Historical variability on July 26 includes occasional outliers (e.g., 31°C or 27°C), which the current odds completely dismiss.

What to watch

• Official announcement of the day's high temperature from Shenzhen's weather station (likely late afternoon local time) would resolve all markets immediately.
• Any midday report of a current temperature near 28°C or 30°C could shift odds if it suggests the final high will deviate from 29°C.
• No other dated catalysts are identifiable from the provided data.
