Active sub-markets
Market context
Gold futures on the CME are currently trading around $2,050–$2,080 per troy ounce, with the June 2026 contract (GC) serving as the active month through late spring. The market is asking whether spot settlement will touch or exceed a specific price level by the final trading day of June 2026. Polymarket has priced this outcome at 0% YES, meaning traders are either confident the threshold lies well above foreseeable price action or the strike itself sits at an extreme that historical volatility cannot easily reach. On-chain, the conditional tokens representing YES and NO positions settle against USDC on Polygon once CME publishes its official settlement figure on the last trading day of the contract month.
Gold's long-term behaviour offers context: the metal has breached $2,000 multiple times since 2020, peaked near $2,135 in December 2024, and typically experiences seasonal weakness in late spring before summer doldrums. A 0% crowd probability suggests the strike is pitched either significantly above recent highs or reflects a structural view that deflationary pressures or dollar strength will suppress prices through mid-2026. Historical precedent shows gold can swing $100–$150 in a single quarter when geopolitical risk spikes or central banks shift policy stance.
Traders monitoring this contract should track Federal Reserve communications, particularly any signals about rate cuts or inflation persistence, alongside developments in US–China relations and Middle East tensions. The Bank for International Settlements' quarterly reports on currency flows and gold demand, typically published in March and June, can move sentiment sharply. Additionally, any surprise in US inflation data or employment figures between now and June 2026 will ripple through both spot and futures markets, though the current 0% pricing suggests the crowd sees little path to the specified level regardless of near-term catalysts.
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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- What does it cost to trade on Kalshi UK?
- Zero. Kalshi UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, Kalshi UK triggers a quick verification flow that finishes in minutes.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
