Resolution criteria on PolyGram: This market will resolve to “Yes” if the USD-denominated stablecoin supply falls below 99% of total stablecoin supply at any point in 2026. Otherwise, it will resolve to “No.” The resolution source is Artemis (https://app.artemisanalytics.com/stablecoins), using the “Stablecoin Supply by Currency” chart. The USD percentage shown when hovering over a monthly data point will be used. A monthly data point will be considered finalized once the following month’s data point is published. If the resolution source becomes permanently unavailable, the market will resolve based on other reliable crypto data sources.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Will USD-denominated stablecoin market share fall below 99% in 2026? | 11% YES | 89% NO |
USD-denominated stablecoins currently represent approximately 99.5% of the total stablecoin market by supply. For this market to resolve affirmatively, non-USD stablecoins—primarily euro-pegged (EUROC, EURe) and emerging market currencies—would need to capture more than 1% of total stablecoin supply during 2026. This would represent a substantial shift in the composition of a market that has remained remarkably concentrated around the dollar since stablecoins' inception.
Historical precedent suggests such rapid diversification faces structural headwinds. The stablecoin market has grown from roughly $2bn in 2020 to over $150bn by late 2024, yet USD dominance has only strengthened during this expansion. Euro-pegged stablecoins have existed since 2021 but remain below 0.5% market share despite the eurozone's economic significance. Comparable currency diversification in traditional forex and payments systems took decades to materialise; the prediction market's 11% implied probability reflects scepticism that crypto markets will compress this timeline substantially.
Catalysts to monitor include regulatory developments in the EU that might mandate euro stablecoin adoption, significant macroeconomic shifts reducing dollar demand, or major institutional adoption of non-USD stablecoins by exchanges or payment processors. The Polymarket order book currently prices this scenario as a tail event, with traders requiring roughly 9:1 odds against USD stablecoins losing dominance within the settlement window. Any material shift in cross-border payment infrastructure or central bank digital currency adoption patterns could alter these dynamics.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Will USD-denominated stablecoin market share fall below 99% in 2026?" are the same as any other PolyGram crypto-price event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$46K in lifetime turnover and $1K of resting liquidity puts this market in the around the median by volume for crypto contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for 4 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
