Question

Six frontier AI models put this at 18% by 9 Feb 2027. Full reasoning from every model.

WillHappen.ai · Accepted Answer

18% — the median of 6 frontier models, resolving by 2027-02-09.

Answer

Gemini (Google): 8% — A three-month window is too narrow for Washington and Tehran to finalize even an interim pact amid ongoing regional proxy friction. Interim deals between Washington and Tehran historically require 6 to 18 months of technical talks, far exceeding this 90-day horizon. Iran requires front-loaded sanctions relief that the US administration cannot easily deliver without extensive congressional pushback. A coordinated de-escalation by Houthi and Iraqi militias verified by US intelligence would be the only catalyst to alter this timeline.

Answer

Claude (Anthropic): 17% — Depends on whether Washington and Tehran both soften enough to sign any mediated interim text by Feb 2027. US-Iran talks have repeatedly stalled since 2025 over enrichment limits, sanctions relief sequencing, and domestic political constraints on both sides. Base rate for formal US-Iran agreements historically is low given decades of distrust, though Qatari/Omani mediation has produced partial deals before (e.g. 2023… A major shift like a new shipping crisis escalation forcing urgent de-escalation, or a political reshuffle in Tehran/Washington, would most change this estimate.

Answer

GPT (OpenAI): 31% — It turns on whether Tehran and Washington accept limited de-escalation without first resolving nuclear and sanctions disputes. Qatar or Oman can broker talks, but any pact needs White House, Iranian leadership, and likely Israeli-security buy-in by February 2027. Past indirect U.S.-Iran understandings have occurred, but durable written interim deals usually stall on sanctions relief and verification. A sustained Strait of Hormuz crisis or release-for-restraint package would sharply raise the odds.

Answer

Grok (xAI): 18% — US and Iranian leaders must both accept a Qatari-mediated formula in under 90 days. Neither capital has closed a formal pact since the 2015 JCPOA; talks routinely stall for years on verification and sanctions. The 90-day window to 9 Feb 2027 sits far below the historical pace of even interim nuclear or maritime deals. A sudden Hormuz blockade or new US administration mandate could force speed, but no such trigger is visible now.

Answer

DeepSeek (DeepSeek): 22% — Only a US-Iran deal trading sanctions relief for nuclear/shipping limits counts, and neither side has shown it will sign before February. Mediators (Qatar, Oman) have floated formulas since 2025, but Washington demands uranium enrichment caps and Tehran demands sanctions relief first. The 2023 Qatar-brokered prisoner swap and 2015 JCPOA took 2+ years of talks; a full interim pact in under 3 months is far above that base rate. A verified IAEA inspection breakthrough or a US sanctions waiver would most change my mind, but no such step is scheduled before February 2027.

Answer

Qwen (Alibaba): 14% — Three months is short for a formal US-Iran pact even at interim level; domestic politics on both sides are the binding constraint. Base rate is stark: since JCPOA collapse in 2018, only the Sept 2023 prisoner swap qualifies as a mediated US-Iran arrangement, and that took months of back-channeling… A Trump administration faces congressional and ideological resistance to any concession to Iran; Khamenei's office has repeatedly rejected negotiations under maximum… The one development that would shift this sharply upward: a major shipping-lane escalation (e.g., Hormuz closure threat) forcing both sides to accept a narrow…
