Shanghai June 10 Low Temp: 17°C at 32%

A single-day temperature forecast market for Shanghai has traders picking between eleven outcomes, and the data is pointing in a specific direction. The market prices 17°C as the most likely minimum temperature for June 10, sitting at 32.5% implied probability. That’s a plurality, not a consensus, and it leaves almost 70% of the contract priced toward every other outcome.

The market question asks: what is the lowest temperature in Shanghai on June 10? The YES contract for 17°C trades at $0.33, the NO contract at $0.68, with resolution set for June 10, 2026 at 12:00 UTC. Total volume sits at $5,674, with $5,074 of that moving in the last 24 hours.

How the Shanghai June 10 Minimum Temperature Contract Works

This contract resolves YES if Shanghai’s recorded minimum temperature on June 10 lands exactly at 17°C. Any other value, whether 16°C, 18°C, or anything else across the eleven listed outcomes, resolves YES for a different contract and NO for this one. The resolution source is the market’s designated data provider for the June 10 reading.

• YES ($0.33, 32.5% probability): Shanghai’s minimum temperature on June 10 is exactly 17°C.
• NO ($0.68, 67.5% probability): Shanghai’s minimum on June 10 lands at any other value.

The NO contract pays out across a wide range of scenarios. Shanghai’s June minimum temperature history shows readings commonly clustered between 18°C and 22°C during early June, with the city entering its pre-Meiyu season by mid-month. A reading above 17°C, which climatological norms favor, is exactly what resolves NO for this contract. The market isn’t saying 17°C is unlikely in absolute terms. It’s saying the distribution of possible outcomes is wide enough that any single value carries meaningful probability against it.

Momentum and Market Signals

The momentum composite here is notable. The 24-hour price change of +18% is substantial for a short-duration weather market, and a trend score of 50.42 suggests neither strong continuation nor reversal. The most likely driver is traders positioning ahead of the June 10 resolution, with updated forecast data from China Meteorological Administration or global weather models shifting sentiment toward 17°C as a plausible floor for the overnight low.

Total volume of $5,674 is thin. The 24-hour volume of $5,074 means almost all trading in this contract happened in the last day, which is typical for short-window weather markets as resolution approaches. Liquidity of $19,756 is relatively deep compared to volume, meaning the order book can absorb moderate-sized bets without sharp price distortion. Still, at this volume level, a single well-funded trade can reprice the contract meaningfully.

• The 17°C outcome gained roughly 18% in implied probability over 24 hours, likely tied to updated regional weather model runs showing cooler overnight conditions than earlier forecasts suggested.
• The 24-hour volume of $5,074 represents the vast majority of all trading in this market, signaling a late-breaking concentration of bets.
• Liquidity of $19,756 is healthy relative to volume, but thin volume overall means price can move sharply on any new data or large single trade before June 10 noon resolution.
• The 1-hour change of 0.0% indicates the current 32.5% price has stabilized after the prior 24-hour run-up.
• Trader sentiment is strongly bearish on YES at 67.5% NO, consistent with the fundamental challenge of any single discrete outcome in an eleven-way market.

Lines Analysis: Shanghai’s Overnight Low on June 10

Shanghai’s climatological baseline for early June minimum temperatures sits roughly in the 18°C to 21°C range, based on historical station data from Shanghai Hongqiao and Pudong International Airport monitoring. June 10 sits just before the Meiyu front typically intensifies, a period when overnight lows can dip if pre-frontal winds bring drier, slightly cooler air from the northwest. That dynamic is what makes 17°C credible rather than exotic. The market’s 32.5% on 17°C reflects a real meteorological scenario, not a long-shot bet.

What makes NO compelling here is pure probability math. Eleven discrete outcomes split the distribution, and even the leading outcome captures only a third of the probability. Weather model ensembles for Shanghai on June 10 currently show the overnight low distribution centering around 18°C to 20°C, which means 17°C is at the cooler edge of the plausible range. A reading of 18°C or 19°C, each priced separately, would collectively represent a large share of remaining probability and would resolve this specific contract NO.

• China Meteorological Administration’s updated 72-hour forecast for Shanghai will be the single most important data input before resolution. Any shift toward 18°C or above reprices this contract sharply lower.
• European Centre for Medium-Range Weather Forecasts ensemble runs showing a tighter cold pool over the Yangtze Delta region would support the 17°C outcome.
• The Meiyu front’s exact timing matters. Early onset before June 10 would likely push minimums higher, not lower, as moisture and cloud cover trap overnight heat.
• Any late-evening June 9 temperature readings from Shanghai surface stations trending below 19°C would signal movement toward the 17°C range.
• Competing contracts for 18°C and 19°C absorbing significant new volume would signal traders are pricing the low as warmer than 17°C.

The market’s $5,674 in total volume is small. That context matters for confidence. The 32.5% on 17°C reflects informed positioning, but this is not a deep-volume market with thousands of traders refining a consensus. Here’s what the measurements are telling us: the current forecast distribution puts 17°C at the lower end of the plausible range for June 10, giving it real but minority probability. The data doesn’t care about the politics of the bet. It cares about whether Shanghai’s overnight low clips the cooler side of the envelope.

LINES VERDICT

17°C IS A LIVE OUTCOME BUT FACES A WIDE FIELD

The market correctly prices 17°C as the single most probable discrete outcome in an eleven-way split, but climatological norms and current forecast positioning favor warmer values that would resolve this contract NO.

What the market says: 32.5% implied probability means traders assign roughly one-in-three odds to a 17°C minimum. That’s a plurality in a fragmented field. With resolution in less than 36 hours, any updated forecast model run can move this price sharply before June 10 noon.

Key unknown: China Meteorological Administration’s next official 24-hour forecast update for Shanghai, and whether global ensemble models shift the overnight low distribution cooler or warmer than the current 18°C to 19°C center of mass.

Scientific and Meteorological Context

Shanghai’s June climate sits in a transitional window. The city typically records minimum temperatures between 18°C and 22°C in early June, with occasional dips to 16°C or 17°C when pre-frontal dry air advection occurs before the Meiyu season fully establishes. The market is pricing uncertainty, not science. The uncertainty here is real: the difference between a 17°C and an 18°C minimum can depend on whether cloud cover breaks before dawn, allowing radiative cooling to push the surface temperature that extra degree lower. That physical mechanism is what keeps 17°C in the conversation even when the central forecast sits warmer.

Before June 10 resolution, the events that matter most are the final 24-hour forecast update from China Meteorological Administration and any surface observation trends from Shanghai’s urban monitoring network on the evening of June 9. If those readings show temperatures dropping through 20°C toward 18°C by midnight, the 17°C contract will reprice upward. If they hold at 21°C or above, the probability collapses.

How likely is a 17°C minimum for Shanghai on June 10?

The market prices it at 32.5%, making it the leading single outcome in an eleven-way field. That reflects real meteorological possibility, not high confidence. Climatological norms favor warmer values.

What happens to the NO contract?

NO pays out if Shanghai’s recorded minimum on June 10 is any temperature other than exactly 17°C. Given the wide distribution of possible outcomes, NO currently prices at 67.5%.

What data would move this contract’s price?

An updated China Meteorological Administration forecast showing the overnight low trending toward 17°C would push YES higher. A forecast holding at 18°C to 20°C would push it lower. Resolution is less than 36 hours away.

When does this contract resolve?

Resolution is set for June 10, 2026 at 12:00 UTC. The contract closes based on the official minimum temperature recorded for Shanghai on that date.

Is the volume reliable enough to trust the price?

Total volume is $5,674, which is thin. Most of that traded in the last 24 hours. Liquidity of $19,756 is healthy relative to volume, but a single large trade could reprice this contract meaningfully before resolution.
