Resolution criteria on PolyGram: This market will resolve to "Yes" if there is an official ceasefire agreement, defined as a publicly announced and mutually agreed halt in military engagement, between Russia and Ukraine by May 31, 2026, 11:59 PM ET. If the agreement is officially reached before the resolution date, this market will resolve to "Yes," regardless of whether the ceasefire officially starts afterward. Only ceasefires which constitute a general pause in the conflict will qualify. Ceasefires which only apply to energy infrastructure, the Black Sea, or other similar agreements will not qualify. Any form of informal agreement will not be considered an official ceasefire.
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
| Russia x Ukraine ceasefire by May 31, 2026? | 100% YES | 0% NO |
The question concerns whether Russia and Ukraine will reach a formal, mutually agreed ceasefire halting general military operations by the end of May 2026. This requires a publicly announced agreement on a comprehensive pause in fighting, excluding sectoral arrangements such as energy infrastructure truces or maritime corridors. The 3% implied probability reflects the substantial distance between current positions and a negotiated settlement within approximately 16 months.
Historical precedent suggests comprehensive ceasefires in major interstate conflicts typically emerge only after military exhaustion, significant diplomatic pressure, or major shifts in third-party support. The Minsk agreements (2014–2015) and subsequent Normandy format talks failed to produce lasting ceasefires despite international mediation. The 2022–2024 period saw no sustained negotiations, with both sides maintaining maximalist territorial demands. Comparable conflicts—such as the 1973 Yom Kippur War ceasefire or the 1991 Gulf War armistice—materialised following decisive military outcomes or superpower intervention, conditions not currently evident.
Key catalysts include shifts in US policy under the Trump administration, which has signalled interest in negotiated settlements; announcements of direct talks between Russian and Ukrainian delegations; and changes in military momentum on the ground. Reuters reported in December 2024 that Trump's team was exploring ceasefire frameworks, though substantive negotiations had not commenced. Any formal ceasefire announcement would require both parties to agree publicly, making diplomatic statements and official government communications the primary indicators traders should monitor through May 2026.
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.
