The market assigns 61.5% probability to July 3 reaching a daily high of exactly 31°C. That is a narrow band. Weather resolves fast, and this contract closes in under 48 hours. The market question asks: what will the highest temperature in Tel Aviv be on July 3? The 31°C outcome trades at $0.62 YES and $0.39 NO, closing at 2026-07-03 12:00. Total volume stands at $11,955, nearly all of it placed in the last 24 hours. How the Tel Aviv July 3 Temperature Contract Works This contract resolves to YES if the daily high in Tel Aviv on July 3 lands at exactly 31°C. A reading of 30°C, 32°C, or anything else resolves the 31°C contract to NO. The resolution source is market resolution, meaning the operator applies an official weather observation to determine the outcome. Each temperature band from 27°C or below through 37°C or higher trades as its own separate contract. 31°C YES trades at $0.62 (61.5% implied probability).31°C NO trades at $0.39 (38.5% implied probability). A NO outcome pays when Tel Aviv’s July 3 maximum diverges from exactly 31°C. A reading one degree higher or lower is sufficient. Late-breaking forecast revisions, sea breeze timing, or an unexpected pressure shift can push the actual high into the 30°C or 32°C range without any anomaly in the broader pattern. Momentum and Market Signals Frame a Fast-Moving Price Sponsored Partner The momentum composite tells a clear story. This contract opened the day at $0.42 and gained roughly 15 percentage points in a single session. Combined with a trend score of 38.65 and flat movement in the last hour, the market settled into its current range after absorbing a sharp directional bet. No further catalyst has arrived to push it higher or pull it back. Total volume is $11,955 against $11,960 in the last 24 hours. Those two figures are nearly identical, confirming this market is brand new and all activity is today’s activity. Liquidity sits at $58,265, which is deep relative to volume. That liquidity cushion means a single new large bet would not move the price dramatically, but it also signals the market maker is carrying real exposure across all the temperature bands simultaneously. The 1h price change is flat at 0.0%, meaning the morning’s move has stalled at current levels.The 24h move of roughly plus 15 points reflects the full repricing from open to now.Thin trading volume below $15,000 means one informed forecast update could reprice this contract sharply before close.Liquidity depth at over $58,000 provides a buffer against random noise but does not guarantee price stability.The trend score of 38.65 sits in neutral-to-bearish momentum territory, suggesting the initial impulse has exhausted itself. Lines Analysis: What the Measurements Are Telling Us Here’s what the measurements are telling us. July in Tel Aviv runs hot. Historical July averages sit around 29°C to 30°C for daily highs, with frequent spikes into the low 30s when inland pressure systems dominate. A 31°C reading is not extreme. It falls squarely in the normal July range, which explains why the market converged on this band as the modal outcome. The data doesn’t care about the politics of which degree wins. It cares about where the ensemble forecast is clustering. What makes NO real here is the precision requirement. Weather models have skill at the three-day range, but their confidence interval around a daily maximum spans one to two degrees in either direction. A 32°C outcome is not a tail event. Neither is 30°C. The market is pricing uncertainty, not science. The 61.5% probability on a single one-degree band is already a strong statement for a product this granular. Any forecast shift toward 32°C before close would reprice the 31°C contract sharply lower and lift the 32°C band.A Mediterranean sea breeze event arriving earlier than modeled would pull the high toward 30°C.Synoptic pattern confirmation from the 00Z or 12Z model run on July 2 would either reinforce or challenge the current pricing.Official station data from the Israel Meteorological Service will determine resolution, so any gap between forecast and observation matters.If the broader heat pattern intensifies overnight, the 33°C and 34°C bands could attract late money away from the 31°C contract. Total volume of $11,955 is modest for a science-category contract. The data favors the 31°C band as the modal forecast outcome, but the inherent imprecision of single-degree temperature forecasting keeps this market genuinely competitive. Neither side can claim certainty at this resolution. LINES VERDICT NARROW FAVORITE, REAL UNCERTAINTY The 31°C band holds the strongest single-outcome probability in a fragmented field, but one-degree precision cuts both ways. The market is right to price this as a modal outcome, not a lock. What the market says: 61.5% implies the market sees 31°C as the most likely single daily high, but nearly four-in-ten dollars bet against it. With resolution in under 48 hours, any forecast revision before July 3 morning will move this price fast. Key unknown: The July 2 evening model run from the Israel Meteorological Service and European ensemble forecasts are the single most important data inputs left before resolution. A one-degree shift in the forecast consensus would reprice multiple bands simultaneously. Frequently Asked QuestionsWhat does 61.5% probability mean for the 31°C outcome?The market assigns a roughly six-in-ten chance that Tel Aviv's July 3 daily maximum lands at exactly 31°C. Other temperature bands each carry their own separate probability.How does the NO contract pay out here?NO pays if Tel Aviv's July 3 high is anything other than 31°C. A reading of 30°C or 32°C is sufficient to resolve the 31°C contract to NO.What data or event would move this price most before resolution?Updated ensemble forecasts from the Israel Meteorological Service or European models on July 2 would be the primary repricing trigger for all temperature band contracts.When does this market resolve?The contract resolves at 12:00 on July 3, 2026, based on the official observed daily maximum temperature in Tel Aviv applied by the market operator.Is the volume and liquidity reliable for this market?Total volume is under $15,000, which is thin. Price can move sharply on a single new trade. Liquidity of $58,265 provides some buffer but does not guarantee stability.How is the Smart Money Index calculated?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.What is a convergence signal?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.Is Lines a market operator?No. Lines is an editorial and data product. We do not operate prediction markets, custody funds, or accept trades.

Forecast Locks In at 31°C If July 2 model runs from European and regional ensembles tighten around a 31°C maximum, traders will push the YES price above 0.70. A stable synoptic pattern with no sea breeze disruption and no inland heat surge would keep the forecast centered on the current band and attract late capital. Forecast Drifts One Degree Higher If updated models shift the July 3 maximum toward 32°C, the 31°C contract reprices sharply lower. The 32°C band would absorb much of the capital leaving 31°C. With thin total volume, this move could happen quickly on a single forecast publication. Sea Breeze Pulls High to 30°C A Mediterranean sea breeze arriving earlier than modeled on July 3 morning could cap the daily high at 30°C. That would resolve the 31°C contract to NO and lift the 30°C band. Sea breeze timing is notoriously difficult to model at 48-hour range. Heat Surge Pushes Above 33°C A sudden inland pressure intensification overnight on July 2 could drive the July 3 high to 33°C or beyond, collapsing the 31°C and 32°C bands simultaneously. This is a low-probability scenario but consistent with the broader Eastern Mediterranean summer pattern when dry easterly flow strengthens unexpectedly. Key macro factor: The Eastern Mediterranean summer of 2026 is running within a warm regime consistent with recent years, which increases the base rate for daily highs in the 31-33°C range in Tel Aviv during early July.
