Resolution criteria on PolyGram: This market will resolve to "Yes" if China (People's Republic of China) announces it has established or otherwise de facto establishes an aerial or naval blockade for the territory of Taiwan (Republic of China) by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A qualifying blockade is: - Prevents the normal ingress or egress of foreign commercial traffic to or from Taiwan Island’s main ports or airports by threat or use of force for ≥ 24 hours. - Covers part or whole of the main island of Taiwan (Formosa).
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 China blockade Taiwan by in 2026? | 5% YES | 95% NO |
A blockade of Taiwan—whether aerial or naval, partial or complete—would represent a dramatic escalation of cross-strait tensions and constitute a major geopolitical rupture. The market settles affirmatively only if China establishes and enforces restrictions preventing normal commercial traffic to Taiwan's main ports or airports for at least 24 hours by end-2026. The current 5% implied probability reflects market assessment that such an overt action remains unlikely within this 24-month window, despite elevated baseline tensions.
Historical precedent offers limited direct comparison. China's 1995–1996 missile exercises near Taiwan caused temporary shipping disruptions but fell short of a formal blockade. The Cuban Missile Crisis and Berlin Blockade demonstrate that sustained blockades typically follow explicit political demands and represent escalation after diplomatic breakdown. Most analysts distinguish between coercive military exercises—which China has conducted with increasing frequency—and a blockade proper, which would signal intent to compel political capitulation and invite international response. Recent statements from Chinese officials emphasise "reunification" rhetoric rather than imminent blockade announcements.
Traders monitoring this market should track several indicators: statements from China's military leadership regarding Taiwan operations; any major shift in US military posture or Taiwan defence spending; developments in cross-strait trade negotiations; and statements from regional powers including Japan and ASEAN. The 2024 Taiwan presidential transition and any subsequent diplomatic incidents would merit close attention. Scheduled military exercises by either side, particularly if they restrict civilian shipping lanes, could trigger temporary repricing, though exercises alone would not satisfy settlement criteria without de facto enforcement lasting 24+ hours.
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.
