Answer

Gemini (Google): 82% — Direct trilateral leader-level peace talks are blocked by incompatible territorial demands and Moscow's refusal to recognize Kyiv. Russia's next major elections are the Sept 2026 State Duma races or March 2030 presidential election; this window is tight. Bilateral or proxied diplomacy remains Moscow's preference, as Putin avoids granting Zelenskiy equal trilateral standing with Washington. A catastrophic Russian military collapse or unilateral U.S. coercion forcing immediate direct summitry would lower this probability.

Answer

Claude (Anthropic): 78% — Whether Putin agrees to sit with Zelenskiy before Russia's 2026 Duma vote or later polls is the crux. Zelenskiy himself has said no trilateral summit will occur before Russian elections, matching the base case for stalled talks. Russia has consistently resisted direct Putin-Zelenskiy talks, preferring bilateral US-Russia or proxy negotiations, which sets a high bar for a formal trilateral summit. A sudden ceasefire breakthrough or US-brokered pressure campaign could force an early summit, which is the main scenario that would flip this.

Answer

GPT (OpenAI): 82% — Moscow has little incentive to join a U.S.-Ukraine summit before its next presidential election, likely due in March 2030. Russia's last presidential election was March 2024; its six-year constitutional term points to the next regular vote in March 2030. A trilateral summit needs Kremlin assent and a sufficiently mature ceasefire framework, neither of which is usually built quickly in active wars. I would cut this sharply if Russia and Ukraine accept a monitored ceasefire with Washington as guarantor before 2028.

Answer

Grok (xAI): 97% — No US-RU-UA peace summit can be staged in the remaining days before the 2026 Duma vote. Zelensky has already publicly ruled out any trilateral meeting before the elections. Putin and the US would both have to reverse course and schedule talks with zero lead time and no existing channel. No such summit has occurred since 2022; the base rate in a three-day window is effectively zero.

Answer

DeepSeek (DeepSeek): 88% — Putin has no incentive to sit down before the 2028 vote, and Kyiv won't accept terms that make him look like a winner. Russia's next presidential election is March 2028, so the window runs past the resolve date; no trilateral format has ever convened since Feb 2022. A summit requires Putin to accept Zelenskiy as a counterpart and Washington to broker terms Moscow currently rejects, including a ceasefire line. Base rate for leader-level trilateral summits during active war is near zero; only a battlefield collapse or U.S. pressure shift would move this.

Answer

Qwen (Alibaba): 97% — Russia's next federal elections (Duma, Sept 2026) are already past; the next presidential election isn't until 2030. Russia's State Duma elections were held September 2026, so 'next elections' likely refers to the 2030 presidential cycle—far beyond the resolution date. Zelenskiy himself publicly ruled out a trilateral summit before Russian elections, and no credible diplomatic track exists to produce one by Sept 2027. A development that would change this: a sudden ceasefire framework brokered by a third party (e.g., China or Turkey) creating pressure for a summit before the resolution…
