Wellington July 22 High Temperature: Market Locked at 14°C

This market is done moving. The 14°C outcome for Wellington’s highest temperature on July 22 is sitting at full implied probability, and the data got there before most traders even opened their dashboards. A jump of nearly 45% in 24 hours tells you everything about how fast meteorological certainty can collapse a prediction market into a foregone conclusion. The market has priced this as settled.

The market question asks for the highest temperature recorded in Wellington on July 22, 2026. The 14°C outcome carries a price of $1.00 against $0.00 for any alternative. Resolution closes at 12:00 on July 22. Total volume stands at $83,437, with $62,474 of that arriving in the last 24 hours.

How the Wellington Temperature Contract Works

This contract resolves YES on 14°C if official weather records confirm that as Wellington’s daily maximum temperature on July 22. Alternative outcomes include everything from 9°C or below up to 19°C or higher. The market resolves on official measurement at the stated deadline.

• 14°C (YES): $1.00 per share, implying 100% probability of resolution.
• All other outcomes (10°C through 19°C or higher): $0.00, implying zero probability.

For any alternative outcome to pay out, official Wellington temperature records would need to show a different daily maximum. Wellington’s July climate sits firmly in mid-winter, with typical highs ranging between 11°C and 14°C. A reading outside that band today would require an unusual weather event. The measurement window is narrow, the deadline is hours away, and the market has already absorbed whatever forecast data drove the 24-hour surge.

Momentum and Market Signals

The momentum composite here is unusually clean. A trend score of 64.07, combined with a 45% price jump in 24 hours and flat movement in the last hour, describes a market that sprinted to certainty and stopped. The driver was almost certainly updated short-range weather forecast data released on July 21, which pushed the price through three separate surges totaling roughly 45 percentage points in a single day.

Total volume of $83,437 with $62,474 arriving in 24 hours signals genuine conviction, not thin noise. Liquidity of $262,219 dwarfs the volume, which means the order book is deep relative to trading activity. This is not a market that will move sharply on a late trade. The capital has spoken.

• The 24-hour price surge of nearly 45% reflects traders absorbing short-range forecast data confirming 14°C as the expected Wellington maximum.
• The one-hour change of 0% confirms the market has reached equilibrium. No new information is arriving that challenges the consensus.
• Liquidity of $262,219 against $83,437 in volume means this contract is overcapitalized relative to activity, a hallmark of a market that has stopped being contested.
• Open interest at zero indicates no unresolved positions remain open, consistent with a market approaching its resolution window.
• Trader sentiment at 100% YES and 0% NO reflects complete directional alignment, which is rare and meaningful.

Lines Analysis: What the Wellington Data Is Saying

Wellington sits at roughly 41 degrees south latitude, putting its July climate firmly in the Southern Hemisphere winter. Average July maximums in Wellington cluster between 11°C and 13°C, with warmer days reaching 14°C to 15°C during mild spells. A 14°C reading is entirely within the normal range for a relatively mild winter day. Here’s what the measurements are telling us: nothing anomalous needs to happen for this outcome to resolve correctly. The forecast data that arrived on July 21 was specific enough to drive three separate price surges totaling nearly half the probability scale in one day.

The data doesn’t care about the politics, and in this case the meteorology is equally indifferent to drama. For any alternative outcome to disrupt this market, Wellington would need an abrupt cold snap pushing the maximum below 13°C, or an unexpectedly warm front pushing it above 15°C. Neither scenario is being priced at any non-zero probability. The market isn’t pricing uncertainty here. It resolved that question yesterday.

• MetService or equivalent New Zealand weather authority: any last-minute forecast revision before 12:00 July 22 would be the only data capable of repricing this contract.
• Official temperature observation at Wellington Airport or closest official station: the final reading against the 14°C threshold is the sole resolution trigger.
• Sustained wind or precipitation data: Wellington’s notorious wind can suppress daytime highs; confirmation of calm conditions supports the 14°C reading.
• Regional pressure systems: a blocking high over the lower North Island through July 22 would be consistent with the mild-day temperature profile this contract implies.

With $83,437 in total volume and a market locked at $1.00, there is no analytical ambiguity left to resolve. The data favors the 14°C outcome completely. The only open question is whether the official measurement, when published, confirms what short-range forecasts already told the market on July 21.

LINES VERDICT

RESOLVED IN PRACTICE

The 14°C outcome absorbed nearly the entire probability curve in a single day, driven by short-range forecast data that left no meaningful room for alternative outcomes. The market is pricing certainty, not speculation.

What the market says: 100% implied probability with hours until resolution and a deep order book means this contract is as close to settled as a prediction market gets before official confirmation. Volatility before the 12:00 deadline is essentially zero.

Key unknown: The single event that could reprice this contract is the official temperature observation at Wellington’s designated measurement station before the 12:00 resolution window closes. Every other variable has already been absorbed.
