Highest temperature in Houston on July 15?

Platform comparison

Market context

Houston’s William P. Hobby Airport will record its peak temperature for 15 July 2026, with the market resolving to the Fahrenheit range containing that value. The crowd-implied probability of a YES outcome sits at 0%, suggesting traders expect the temperature to fall outside the specific range offered, though the exact range is not defined in the prompt. Historically, mid-July in Houston sees highs consistently between 93°F and 97°F at Hobby Airport, with 2023 and 2024 both peaking at 96°F on 15 July, according to Wunderground’s daily archives. This pattern frames the 0% probability as potentially mispriced if the market’s YES range aligns with typical summer extremes, unless the range is set unusually low or high.

Traders should monitor the National Weather Service’s 7-day forecast for Houston, updated daily at 12:00 UTC, which will clarify heatwave potential ahead of settlement. A sudden shift in funding rates on BTC or ETH perpetuals, or a spike in USDC stablecoin flows into prediction markets, could signal whale positioning on temperature outliers. Recent crypto data from Coinglass shows elevated open interest in weather-linked derivatives during US summer heatwaves, often coinciding with BTC funding rate spikes above 0.05%. Settlement occurs in USDC at 2026-07-15T12:00:00Z, with on-chain resolution sourced directly from Wunderground’s KHOU station data, ensuring transparent, non-custodial settlement aligned with btc-prediction.bet’s on-chain mechanics.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

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 are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

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?

In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
