6% — the median of 6 frontier models, resolving by 2026-10-30.

Answer

Gemini (Google): 3% — Direct Russian strikes on European states risk triggering NATO Article 5 or severe retaliation that Moscow actively seeks to avoid. A 30-day window is far too narrow for the dramatic escalation pipeline required for an intentional kinetic attack on a European neighbor. While stray debris has fallen in Romania and Moldova, confirmed deliberate military strikes against European territory have zero baseline. A direct Polish or Baltic border provocation verified by NATO command would sharply raise this probability.

Answer

Claude (Anthropic): 6% — This turns on whether Russia would risk direct NATO/EU confrontation, which remains a red line despite rhetoric. Russia has issued similar warnings before without following through, favoring hybrid/gray-zone tactics like drone incursions over overt strikes. A direct strike on European soil risks NATO Article 5 invocation, a threshold Russia has consistently avoided even amid Ukraine war escalation. One-month-old window and heated rhetoric slightly raise risk above historical baseline, but no concrete mobilization or specific target has been reported.

Answer

GPT (OpenAI): 7% — It turns on whether Moscow accepts a direct NATO confrontation rather than relying on covert or Ukrainian-theater pressure. A confirmed strike in a European state would require Russian forces to cross a politically explosive threshold within 30 days. Since 2022, Russia has avoided acknowledged kinetic attacks on NATO territory despite repeated escalation rhetoric and border incidents. I would raise this sharply if NATO intelligence reported imminent Russian missile, drone, or sabotage operations with attributable command links.

Answer

Grok (xAI): 8% — Whether Putin orders a kinetic strike on non-Ukrainian European soil in the next 30 days. NATO Article 5 has deterred deliberate Russian strikes for 4+ years despite drones over Poland/Romania. UNGA rhetoric is cheap; no targeting or force posture shift reported that would enable a strike by 30 Oct. Non-NATO options (Moldova) remain possible but still risk wider war, keeping odds far below historical incident rates.

Answer

DeepSeek (DeepSeek): 6% — This turns on whether Moscow decides a demonstrative strike on NATO soil is worth the Article 5 risk. Putin has made such threats repeatedly since 2022, yet Russia has struck NATO territory only via drones that strayed, not deliberate military strikes. Any deliberate strike would trigger Article 5 consultations and likely direct NATO response, a cost Moscow has avoided for four years. The one development that would change my mind is credible evidence of Russian intent to test NATO's red line, such as a strike on Baltic infrastructure or a Polish…

Answer

Qwen (Alibaba): 4% — Russia would need to accept NATO Article 5 escalation risk, which has deterred them for 30+ months of war. Russia has struck Ukraine daily for 3+ years but never deliberately targeted NATO/EU territory, even after provocations like the Nord Stream aftermath or drone… A deliberate strike on a European nation would trigger Article 5 or equivalent collective defense, representing an existential escalation Russia's conventional forces… The only realistic path is an accidental strike (stray missile/drone), which has happened near borders but never confirmed as a deliberate attack on sovereign territory…
