Paris June 9 Low Temp: Will 11°C Hit?

A single-day temperature market is about as precise as prediction markets get. Traders are betting on whether Paris records exactly 11°C as its lowest temperature on June 9, 2026. At 42% implied probability, the market treats this outcome as a coin flip leaning toward no.

The market question asks: what is the lowest temperature in Paris on June 9? The 11°C outcome trades at $0.42 YES and $0.58 NO. The market resolves at noon UTC on June 9. Total volume stands at $1,723, with $1,651 of that traded in the past 24 hours.

How the 11°C Contract Works

YES pays out if official measurements confirm Paris records exactly 11°C as the June 9 overnight low. NO pays out if the recorded low lands on any other outcome, including 10°C, 12°C, 9°C, 13°C, or any temperature outside that range. Resolution follows official meteorological data.

• YES ($0.42): Paris records exactly 11°C as the June 9 low temperature.
• NO ($0.58): Paris records any other temperature as the June 9 low.

The NO side has a structural advantage in any single-degree temperature market. There are eleven competing outcomes listed in this contract. Even if 11°C is the single most likely outcome, the probability of any one precise degree landing is naturally constrained. The NO side wins if the low lands at 10°C, 12°C, or anywhere else. That is the arithmetic that keeps YES below 50%.

Momentum and Market Signals

The momentum signal here is sharp and recent. The 24-hour price change shows a 23% jump in the YES price, driven by price moves of roughly 5.5%, 10.5%, and 8.5% across June 7 and June 8. The trend score sits at 50.41, roughly neutral, suggesting the surge is stabilizing rather than accelerating. That pattern points to traders updating on incoming forecast data as June 9 approaches.

Total volume is $1,723, with $1,651 traded in the last 24 hours. Liquidity sits at $18,749. Volume is well below $1 million, which means this market can reprice sharply on a single updated weather forecast or a small cluster of new trades. The order book depth is thin. Any forecast revision moving Paris overnight lows up or down by even one degree would shift the price meaningfully before resolution.

Key Factors

• The YES price jumped 23% in 24 hours, signaling traders are reacting to updated short-range weather forecasts pointing toward the 11°C range.
• The 1-hour change is flat at 0.0%, suggesting the recent surge has paused and the market is waiting for final forecast confirmation.
• Thin volume under $1,723 total means any single large trade or fresh meteorological data can move this price sharply before the June 9 noon resolution.
• Eleven competing outcomes dilute the probability of any single temperature landing, which structurally caps the YES price even when 11°C is the consensus forecast.
• The trend score of 50.41 reflects balanced uncertainty, not a conviction move in either direction.

Lines Analysis: Paris June 9 Low

The 23% surge in YES price over 24 hours is the clearest signal in this market. Traders updated their positions as short-range forecasts for Paris on June 9 moved toward the 11°C neighborhood. European overnight lows in early June typically cluster between 9°C and 14°C, and current forecast models appear to be pointing near 11°C. That is why the market moved. The data doesn’t care about the politics, and here the data is a weather model showing a cool overnight for Paris.

Here’s what the measurements are telling us: 11°C as a June overnight low in Paris is climatologically plausible. The city’s June average overnight low runs around 13°C to 14°C, so 11°C would represent a slightly cooler-than-average night, consistent with forecast patterns showing a cooler air mass moving through northern France in early June 2026. The competing outcomes at 10°C and 12°C are both close enough to matter. A one-degree forecast error in either direction shifts the payout entirely.

The market is pricing uncertainty, not science. Short-range forecasts are accurate to within one or two degrees at this lead time, but a precise single-degree outcome remains genuinely uncertain. The NO side benefits from that uncertainty by aggregating all other outcomes. Total volume of $1,723 reflects a niche, high-precision market with limited liquidity.

Signals to Monitor

• Updated Météo-France or European Centre for Medium-Range Weather Forecasts model runs published on June 8 and early June 9 will be the primary price driver.
• Any forecast shift moving the Paris overnight low from 11°C to 10°C or 12°C would sharply reprice YES downward.
• A model consensus tightening around 11°C in the final 12 hours before resolution would push YES above 50%.
• Actual overnight temperature observations from Paris stations, available in near-real-time, will resolve the market definitively at noon UTC on June 9.

The $1,723 total volume signals a small, specialist market. The side favored by the data is whichever temperature the final forecast models converge on. Right now, the 23% price jump says traders believe that convergence is pointing at 11°C, but the arithmetic of eleven competing outcomes keeps the probability below a majority.

SLIGHT LEAN YES, HIGH UNCERTAINTY

The sharp 24-hour price jump reflects real forecast signal moving toward 11°C. But with eleven outcomes sharing probability in a thin-volume market, any single-degree shift in the actual low repays NO holders entirely.

What the market says: At 42% implied probability, traders see 11°C as the single most likely outcome but not a confident majority pick. With resolution less than 24 hours away, price can move fast on any forecast update.

Key unknown: The final European forecast model run on June 8 evening and the actual Paris station observations overnight on June 8 to 9 will determine whether 11°C holds as the market consensus or neighboring outcomes at 10°C or 12°C absorb the probability.
