Highest temperature in NYC on July 14?

Platform comparison

Market context

The market resolves to the highest temperature recorded at LaGuardia Airport on 14 July 2026, with settlement in USDC and finalisation tied to the 12:00 UTC deadline. Current crowd-implied probability sits at 0% for any outcome below 88°F, reflecting a near-certainty that temperatures will breach that threshold. This aligns with historical patterns where mid-July highs in NYC typically exceed 85°F, often reaching 90°F or more under clear skies and high-pressure systems.

Historical data from the National Weather Service shows LaGuardia frequently records July peaks between 88°F and 95°F, with 2023 and 2024 both exceeding 92°F on similar dates [2]. The 0% probability for lower ranges mirrors past outcomes where cold snaps in mid-July were exceptionally rare, reinforcing the market’s confidence in a hot day. Traders should view the current pricing as consistent with long-term climatic norms rather than an outlier.

Key catalysts include the National Weather Service’s 5-day forecast updates and real-time Wunderground readings, which will determine the final resolution [1]. Watch for shifts in funding rates on BTC and ETH futures, as macro volatility can influence liquidity flows into weather-linked contracts. Whale activity on Polymarket has previously driven sharp repricing in similar weather markets, so monitor spot exchange volumes for early signals of sentiment shifts ahead of settlement.

Methodology

This page reads Highest temperature in NYC on July 14? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

How does UMA secure the resolution?

The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.

Which crypto markets exist on Polymarket?

Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.

Are crypto prediction markets taxable in the US?
