78% yes
Likely yes — current reporting shows the U.S.-Iran dispute remains unresolved, with Iran maintaining substantial conditions and no confirmed qualifying agreement as of October 15. Only eight days remain before the deadline, making a formal agreement accepted by all listed parties relatively unlikely, though an accelerated diplomatic breakthrough is the main risk.

82% yes
Likely yes — reports as of Oct 14 show unresolved US-Iran talks, insufficient US response, and Iran's parliament speaker explicitly conditioning any reopening on unmet demands, with only days left before the Oct 23 deadline. A last-minute breakthrough is possible given active Iran-Oman shipping talks, but the specific US-Iran bilateral agreement requirement makes a qualifying deal in this short window unlikely.
Gemini 3.8 Flash
84% yes
Likely yes — with only eight days remaining until the October 23 deadline, Iran and the U.S. remain far apart, with Iranian leadership demanding strict preconditions and rejecting recent U.S. proposals. Bilateral diplomatic breakthroughs of this scale typically require extensive technical drafting, making an official joint or mutual announcement highly improbable in this timeframe. The main risk to this outcome is a sudden, fast-tracked interim de-escalation pact brokered by regional mediators like Oman.
Grok 4.6
82% yes
Likely yes — no qualifying US-Iran Hormuz deal has been announced yet and Iranian officials still condition reopening on unmet terms from the June interim while calling the US reply insufficient, leaving only eight days. Oman-Iran route talks do not substitute for a US-Iran diplomatic instrument both sides publicly accept. A last-minute joint announcement before Oct 23 11:59 PM ET would prove this wrong.
DeepSeek V4 Pro
15% yes
Likely no — as of October 14, reports indicate the Iran-Oman framework is still being finalized and Iranian officials say the strait won't reopen until seven conditions are met, with the U.S. response deemed insufficient. The October 23 deadline is close, and no confirmed joint U.S.-Iran announcement exists yet. Main risk: a sudden breakthrough or face-saving joint statement in the next eight days.
Qwen 3.8 Max
92% yes
Likely yes — with only 8 days until the October 23 deadline, the US and Iran remain far apart: Iran insists on seven conditions being met, the US response is deemed insufficient, and neither side has agreed to renewed negotiations, making a formal bilateral diplomatic agreement on Hormuz traffic extremely unlikely in this timeframe. The main risk to this call would be a sudden high-level breakthrough or backchannel deal announced in the final days, but the current trajectory strongly suggests no qualifying agreement will materialize.
Mistral Medium 3.5
75% yes
Likely yes — recent reports show no finalized U.S.-Iran Hormuz agreement, with Iran tying reopening to unresolved conditions and U.S. responses deemed insufficient. The main risk is a last-minute surprise deal by Oct 23.
Kimi K3
80% yes
Likely yes — as of today the strait remains closed, Iran's parliament speaker says it won't reopen until seven conditions are met, and the U.S. response has been deemed insufficient with no renewed negotiations agreed. With only 8 days until the Oct 23 deadline and both sides still far apart, a qualifying announced agreement looks unlikely. The main risk is a sudden diplomatic breakthrough, since Iran-Oman framework talks show channels are active and a deal could be announced quickly if the U.S. concedes on conditions.
GLM 5.3
78% yes
Probably no agreement — as of Oct 15 the talks are stalled, Iran's parliament speaker says the strait will not reopen until seven conditions are met, and the U.S. response to Iran's proposal was reportedly insufficient. With only ~8 days to the Oct 23 deadline and no confirmed framework finalized, a qualifying announced U.S.-Iran agreement looks unlikely. A surprise breakthrough or rapid finalization of the reported Iran-Oman shipping framework could prove me wrong.
MiMo V2.5 Pro
82% yes
Probably not — as of October 15, Iran and the U.S. remain far apart on terms, with Iran insisting on seven conditions being met before reopening the strait and recent reports indicating the U.S. response was insufficient. With only 8 days left before the October 23 deadline and negotiations appearing stalled, a fully announced bilateral Hormuz Agreement meeting the resolution criteria is unlikely. The main risk is a surprise breakthrough deal announced in the coming days, which cannot be ruled out entirely given ongoing backchannel communications.
News the AIs read (Oct 15)
- As of 2026-10-14, there are reports of Iran and Oman agreeing on “safe” shipping routes and a phased navigational framework for the Strait of Hormuz, but those reports say the deal is still being finalized and does not mean the strait is fully open.
- On 2026-10-14, Iranian parliament speaker Mohammad Bagher Ghalibaf was reported as saying the Strait of Hormuz will not reopen until seven Iranian conditions tied to a June interim U.S.-Iran agreement are met.
- On 2026-10-12 and 2026-10-14, reports said the U.S. response to Iran’s proposal was insufficient and that the two sides still lacked agreement on renewed negotiations or unrestricted passage.
- The latest confirmed public facts therefore point to an unresolved situation as of 2026-10-15, with no clearly confirmed announced “Hormuz agreement” meeting the market’s deadline visible in the gathered reports.
- Because the market resolves immediately if no Hormuz agreement is announced by 2026-10-23 11:59 PM ET, the deciding event is that date, not the November election outcome unless an agreement is announced first.
- Senate control is still the other condition for the alternative resolutions, but no latest Senate-control result can be confirmed from the gathered reports here.
- If the market is still unresolved on 2026-10-23, the outcome turns on whether a qualifying Hormuz agreement has been announced by then. …

Hormuz Agreement: A "Hormuz Agreement" will be considered to have occurred if a diplomatic agreement between the United States and Iran over traffic in the Strait of Hormuz is announced by October 23, 2026, 11:59 PM ET.
A diplomatic agreement refers to an official agreement, treaty, deal, or substantially similar diplomatic instrument that establishes agreed actions, policies, obligations, or commitments between the United States and Iran.
A qualifying diplomatic agreement must establish Iranian policies, obligations, or commitments aimed at permitting, restoring, or increasing vessel or shipping traffic through the Strait of Hormuz.
All listed countries must announce their acceptance of the same qualifying diplomatic agreement for the Hormuz Agreement component to be met. A joint announcement will qualify, as will separate announcements from each entity of its own acceptance of an agreement which, taken together, directly indicate that all the listed countries accepted the same agreement. Separate announcements of individual policies will not qualify if the policies are not announced as part of a diplomatic agreement.
Each announcement must be a declarative statement that clearly and unambiguously communicates acceptance of an agreement. Statements that reference ongoing negotiations or a prospective agreement, or that allude to or express support for an agreement without confirming acceptance of the agreement, do not qualify. A qualifying announcement need not reference the agreement by name or use specific terminology, provided it clearly communicates acceptance of an agreement.
Whether announcements from the listed countries represent a diplomatic agreement and whether such an agreement qualifies will be primarily determined through the announcements themselves. Where an announcement is made by all listed countries but, based on the announcements, i...
