89% — the median of 6 frontier models, resolving by 2026-11-08.

Answer

Gemini (Google): 88% — Turns on whether CDP grants an eleventh-hour extension due to platform glitches or corporate pressure. CDP frequently shifts or extends submission deadlines when introducing major platform overhauls or facing technical bottlenecks. With the deadline already published for October 28, 2026, deviations require explicit operational disruptions in the final weeks. A formal extension announcement before October 28 pushes the true close date past this target, dropping odds to near zero.

Answer

Claude (Anthropic): 90% — This is a routine administrative deadline that CDP has consistently maintained in past cycles. CDP has run annual disclosure cycles with set deadlines for over a decade without major disruption. No action is required by external bodies; CDP itself controls and publishes this closing date. Minor risk of a short extension (as happened in some past years) could technically alter the exact closing date.

Answer

GPT (OpenAI): 93% — CDP has publicly set October 28, leaving only a late operational extension or cancellation as a meaningful risk. CDP controls the date and has already announced it, so no legislative or third-party approval is needed before October 28. Annual disclosure cycles commonly keep announced closing dates, though CDP has occasionally extended deadlines for reporting demand or platform issues. A broad technical outage or a formal deadline extension announced before October 28 would materially lower this forecast.

Answer

Grok (xAI): 78% — Whether CDP holds the already-set Oct 28 close or grants a last-minute extension. CDP publicly locked the 2026 corporate cycle to 28 Oct; with 19 days left any change requires a board-level notice. Past cycles show ~1-in-4 late extensions when volume spikes, so this sits modestly below that base. An official ‘no-extension’ bulletin or early portal shutdown would move the odds sharply.

Answer

DeepSeek (DeepSeek): 96% — CDP has already published the October 28 date and the portal is open; only a mid-cycle extension would break it. CDP's own 2026 calendar lists the corporate questionnaire deadline as 28 October, and scores are released the following year, so the date is operational not aspirational. The cycle opened in 2025 with the same portal and no regulator or exchange approval is needed to close it, unlike ISSB-aligned mandates that slip. CDP has occasionally granted short extensions for late filers, but it has never moved the published cycle close date after opening; a major platform outage in the final…

Answer

Qwen (Alibaba): 82% — CDP has historically shifted deadlines mid-cycle; the question is whether they hold the published date or extend it. CDP has extended deadlines in prior cycles (e.g., 2023 saw extensions), so a published date is not a guarantee of the actual close. The context states CDP 'set' this deadline, implying it was officially announced; absent a major disruption, organizations rarely retract a public deadline. A late extension or technical delay would push the close past Oct 28, which would make this false; that has happened before but is not the modal outcome.
