Market context

Natural gas futures (NYMEX NG) will trade during the week of 18–22 May 2026, and this market settles on whether the contract will touch a specific price level during that five-day window. On Polymarket, the contract is currently priced at 0% implied probability, meaning traders are collectively assigning negligible odds to the settlement condition being met. The settlement mechanism uses USDC on Polygon, with conditional tokens reflecting binary outcomes; resolution depends on verified price data from the underlying futures contract at the time the market closes on 22 May at 21:00 UTC.

Natural gas has historically exhibited sharp intraweek volatility, particularly around inventory reports and weather forecasts. The 0% crowd probability suggests either that the target price is far outside the consensus range for May 2026 trading, or that traders view the settlement criteria as extremely unlikely given typical seasonal patterns. May sits in the shoulder season between spring heating demand and summer cooling demand, when NG prices typically consolidate. Comparable May weeks in prior years have seen price ranges of $2–$3 per MMBtu, though extreme weather events or supply disruptions can widen that band significantly.

Traders monitoring this contract should track the weekly EIA natural gas storage report (released Thursdays), which moves prices sharply when inventory builds or draws exceed forecasts. Liquefied natural gas export capacity utilisation, particularly at Sabine Pass and Corpus Christi, influences supply dynamics. Unexpected outages at major production facilities or pipeline infrastructure would be the primary catalyst for outsized moves during the settlement week. Weather forecasts issued in early May will also shape positioning ahead of the window.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
