NYC July 2 High Temp: Will It Hit 98-99°F?

New York City is staring down a dangerous heat setup for July 2, and the prediction market is split on just how hot it gets. The 98-99°F outcome carries a 29.5% implied probability, making it the leading single bucket in a fragmented field. With resolution just hours away, the forecast data and short-term momentum are doing the heavy lifting here.

The market question asks for the highest temperature recorded in NYC on July 2, 2026. The 98-99°F outcome is priced at $0.30 YES and $0.71 NO. The market resolves at noon Eastern on July 2, with total volume of $34,035 and 24-hour volume of $34,045, meaning nearly all trading activity is concentrated in the last day.

How the NYC July Two Temperature Contract Works

This contract resolves YES if the official high temperature recorded in New York City on July 2, 2026 falls between 98°F and 99°F inclusive. The resolution source is Polymarket’s market resolution process, drawing on official temperature records. Ten competing outcome buckets span from 97°F or below all the way to 116°F or higher, so traders are essentially betting on a narrow two-degree slice of a wide probability distribution.

• YES ($0.30, ~30%): The official NYC high on July 2 lands between 98°F and 99°F.
• NO ($0.71, ~70%): The official NYC high falls outside that range, either below 98°F or above 99°F.

The NO position wins in two very different scenarios. A cooler-than-expected day, where temperatures peak at 97°F or below, satisfies NO just as cleanly as an extreme overshoot into the 100-101°F bucket or higher. With multiple alternative buckets trading, the NO price here reflects the sum of all outcomes except the 98-99°F slice, not a directional bet on cooler weather.

Momentum and Market Signals

The momentum composite here is mixed but net positive over 24 hours. The contract gained 10.5% over the prior 24-hour window before pulling back 5.0% in the last hour, with a trend score of 54.47 sitting just above neutral. That pattern is consistent with traders reacting to updated National Weather Service forecast guidance, then partially fading the move as forecast uncertainty narrowed heading into resolution.

Total volume of $34,035 and 24-hour volume of $34,045 confirm that essentially all liquidity entered this market in a single trading day. Liquidity stands at $43,330, which is thin by prediction market standards. At this depth, a single large trade or a Weather Service forecast update can move the price sharply in either direction before resolution.

• The 24-hour price change of +10.5% points to new forecast data lifting confidence in the 98-99°F range as of June 30 and July 1.
• The 1-hour pullback of -5.0% suggests traders trimmed exposure as the forecast cone tightened and competing buckets attracted capital.
• A trend score of 54.47 reflects mild bullish conviction, not strong directional consensus.
• Open interest is $0, meaning all positions are fully settled against current counterparties with no residual exposure.
• Thin liquidity means the 29.5% price is sensitive to any last-minute NWS update or station reading that leaks before official resolution.

Lines Analysis: NYC Heat and the 98-99°F Window

The case for this bucket rests on National Weather Service forecasts pointing to an extreme heat event affecting the Northeast on July 2. High temperatures in the upper 90s to near 100°F have been widely cited for the New York metro area during this period. A surface high pressure system combined with elevated dew points creates the urban heat island conditions that push Central Park or LaGuardia readings into the 98-99°F range. The 29.5% price reflects that this is the most likely single outcome, even though the probability field is distributed across many buckets.

The 100-101°F bucket and the 97°F-or-below bucket are the two most direct competitors pulling capital away from the 98-99°F outcome. Forecast models show meaningful probability that the heat breaks slightly cooler due to cloud cover or a sea breeze intrusion, which would push the high into the 97°F range. Equally, a stronger urban heat island effect or delayed sea breeze could push the reading above 99°F into the 100-101°F bucket. That two-sided squeeze is exactly why the NO price sits at 70.5%.

• A National Weather Service forecast update showing a tighter range around 98-99°F would push this bucket’s price higher quickly.
• Any model shift showing a sea breeze arrival before peak heating hours would redirect capital toward the sub-97°F bucket.
• An early afternoon temperature observation approaching 100°F at a major NYC station would drain this bucket in favor of the 100-101°F outcome.
• Urban heat island conditions at LaGuardia Airport historically run 2-3°F warmer than Central Park, so station selection matters for resolution.
• The thin liquidity means the price can reprice 10-15 percentage points on a single forecast model run released before market close.

Here’s what the measurements are telling us: the 98-99°F bucket is the modal outcome in a genuinely uncertain distribution. Total volume of $34,035 confirms this market attracted real trading interest in the final 24 hours, but the fragmented field means no single bucket commands dominant confidence. The data favors the YES side as the single most likely slice, but the wide probability spread across competing outcomes means NO remains the rational aggregate position.

LINES VERDICT

LEADING OUTCOME IN A FRAGMENTED FIELD

The 98-99°F bucket is the most probable single outcome given current NWS forecast guidance, but a fragmented ten-bucket market means 70% of the probability mass sits elsewhere. The data doesn’t care about the politics of heat records. It cares about where the thermometer stops.

What the market says: At 29.5%, the market treats 98-99°F as the most likely single slice of a wide distribution. Thin liquidity and a resolution window of hours make this price highly volatile through close.

Key unknown: The final National Weather Service forecast update before peak heating on July 2 is the single most important input. Any shift in the predicted high by even one degree will redistribute capital sharply across the competing buckets before resolution.
