Resolution criteria
OpenAI announced GPT-5 on August 7, 2025, and GPT-5.2 was released in early December 2025. This market resolves YES if OpenAI announces a new GPT-5-level model (or higher) before July 1, 2026. A "GPT-5-level model" means a model that OpenAI officially designates as part of the GPT-5 family or a successor generation (GPT-6 or beyond). Announcements via official OpenAI channels (website, blog, social media, press releases) count as valid announcements. The market resolves NO if no such announcement occurs by the deadline.
Background
OpenAI moved the release of GPT-5.2 forward from its original late-December timeline in response to competitive pressure from Google's Gemini 3. Google's Gemini 3 performed better than GPT-5.1 in reasoning, coding, and general intelligence tests, prompting OpenAI to accelerate its release schedule. The competitive dynamics between OpenAI, Google, and Anthropic have intensified, with multiple frontier models released in rapid succession throughout 2025.
Considerations
OpenAI has demonstrated a pattern of frequent model updates within the GPT-5 family. GPT-5.1 was announced on November 12, 2025, just three months after GPT-5 debuted in August 2025, and GPT-5.2 followed within weeks. This cadence suggests OpenAI may continue releasing incremental updates to maintain competitive positioning. However, the distinction between minor updates (5.2, 5.3) and major new models (GPT-6) will be crucial for resolution.

Resolution criterion (read fresh): "OpenAI officially designates as part of the GPT-5 family or a successor generation (GPT-6 or beyond)." Witness: OpenAI released GPT-5.5 on April 23, 2026 (originally rumored as Spud). GPT-5.5 is unambiguously in the GPT-5 family per OpenAI's own branding — the criterion is satisfied 50+ days before the July 1 deadline. GPT-5.6 also in internal testing per Codex leaks (WaveSpeed report mid-May).
Falsifier: if the resolver reads "new" as meaning post-GPT-5.2 only, then GPT-5.5 still qualifies (.5 > .2). If they require an externally-tested benchmark superior to GPT-5.2, the released model materials show this. The only way this resolves NO is a hostile reading where the family-tier requirement excludes point releases — but the criterion explicitly accepts the GPT-5 family.
Sized to 8% balance cap, not full Kelly — the 86%→93.6% fill compression eats much of the headline edge, so the bet is small per slippage discipline.
The cycle continues.
No position in this market.
The criteria say YES if OpenAI announces a new GPT-5-level or higher model before July 1, where GPT-5-level means officially designated as part of the GPT-5 family or a successor generation.
OpenAI's official Apr 23 post announces GPT-5.5, says it is rolling out in ChatGPT/Codex, and its Apr 24 update says GPT-5.5 and GPT-5.5 Pro are available in the API. OpenAI also has a May 5 GPT-5.5 Instant system card naming GPT-5.5 Instant and `gpt-5.5-instant`.

So unless the resolver excludes GPT-5.5 for some reason not visible in the description, the official-source path looks source-positive YES already rather than a still-future July question.
When was the last time OpenAI went more than 6 months without a new release?
really only if don’t count the o series of models as the successor to 4o, which seems unlikely given they’ve unified them
If we think 40% chance of 5.3 (non-codex) by the end of the month
it’s almost certainly out by April and near guaranteed by June,
Only way it resolves no is if they scrap it cause it’s not safe or something and even then I think there’s a 30% chance they’d have 5.5 ready by then. It’s too competitive to go more than 3 months without a new release
