Polymarket
This market will resolve according to the location of the next meeting between Donald Trump and Vladimir Putin between market creation and December 31, 2026, 11:59 PM ET. This market will resolve to "No meeting by December 31" if no qualifying meeting occurs during this market's timeframe. A meeting is defined as any encounter where Putin and Trump are all present and interact with each other in person. An exchange of words, handshake, direct conversation, or other clear personal interaction between the named individuals will qualify as a meeting. Merely standing in proximity, making eye contact, or being present in the same room or event without direct interaction will not qualify. For this market, Gulf states are defined as the six members of the Gulf Cooperation Council (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates). The primary resolution source for this market will be a consensus of credible reporting.
Kalshi
If any country formally leaves the EU by Jan 1, 2030, then the market resolves to Yes.
