What will Gold (GC) hit … by end of December?

Platform comparison

Market context

Polymarket’s price on this contract reflects the chance that CME gold futures’ active month reaches the chosen strike on at least one trading day before the end of December 2026, with settlement in USDC on Polygon through conditional tokens rather than a direct wager on spot gold. In practice, traders are pricing the odds that the front-month GC settlement will print above the threshold during a period when the contract rolls from one delivery month to the next, so the path matters as much as the year-end level.

The comparison set is still skewed to the upside, which helps explain why even a moderate market probability can sit below some bank forecasts. Reuters has reported Goldman Sachs lifting its December 2026 target to $4,900 per ounce, while J.P. Morgan has cited around $6,000 by 4Q 2026 and UBS has pointed to roughly $5,900 at end-2026, with downside scenarios still material if policy tightens or ETF demand weakens.[4][6][15] That range is useful for reading the market: a “Yes” here depends on whether the active CME contract can clear the listed trigger, not on whether gold merely stays elevated.

The main catalysts are US rate expectations, central-bank buying, ETF flows, and any shift in geopolitical risk, because those are the drivers most often cited in the 2026 forecast revisions.[4][6][9][13] Traders also need to watch the CME delivery-cycle calendar, since the active month changes automatically on the First Position Date and the relevant settlement benchmark is the official CME settlement price for that front month.[16]
