About this market

Context

This market will resolve to "Yes" if Barack Obama (@BarackObama) or Joe Biden (@JoeBiden) posts on X about Ukraine between February 28, 2025 3:00 PM ET, and March 7, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No." A qualifying post includes any original post, repost, or reply either from Obama or Biden's verified X account that explicitly mentions Ukraine or Volodymyr Zelenskyy. The content or stance of the post does not matter, but vague references without directly naming Ukraine will not count. The resolution source for this market is https://x.com/BarackObama and https://x.com/JoeBiden however a consensus of credible reporting will also be used.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
