This market resolves YES if, by 2026-09-30 23:59 PT, an official OpenAI source says that a dedicated Cyber model, such as GPT-5.5-Cyber or a direct successor Cyber-named model, is generally or broadly available to approved users of OpenAI's Trusted Access for Cyber program. For YES, access must no longer be described as limited preview, selected partner/smaller-set access, invitation-only access, or restricted only to defenders responsible for critical infrastructure. It is enough if OpenAI says all approved Trusted Access for Cyber users, all verified individual defenders, or all approved enterprise teams can use the dedicated Cyber model under the program. It does not have to be available to ordinary ChatGPT/API users without Trusted Access. This resolves NO if OpenAI only offers standard GPT-5.5/GPT-6/etc. with Trusted Access for Cyber, but the dedicated Cyber model remains limited-preview/selected-partner/critical-infrastructure-only; if OpenAI only says access may broaden later; if only third-party reports claim broader access; or if no official source establishes broad availability by the deadline. If OpenAI renames the program or model family, use the closest direct successor: a dedicated model or access tier explicitly optimized for more permissive cyber workflows, not merely a general-purpose model with ordinary safety classifiers. Creation source check: OpenAI's May 7 post says it is rolling out GPT-5.5-Cyber in limited preview to defenders responsible for securing critical infrastructure, describes GPT-5.5-Cyber as preview access for specialized workflows, says GPT-5.5 with Trusted Access remains the recommended starting point for most security workflows, and says access is expected to broaden over time as verification/safeguards improve.
