GPT-5.6 released on...?

This market will resolve to the company that achieves the highest market capitalization in U.S. dollars based on the official closing price on its first trading day in 2026.

This market will resolve to a company that completes an Initial Public Offering (IPO) between January 1 and December 31, 2026, 11:59 PM ET.

Market capitalization is defined as the total number of outstanding shares multiplied by the closing share price on the first trading day.

If two or more companies have exactly equal highest closing market capitalizations, this market will resolve to the company whose listed name comes first alphabetically.

Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used.

In case the respective company's primary exchange’s official listing page does not report in U.S. dollars, it will be converted to U.S. dollars using the U.S. Federal Reserve Board’s H.10 foreign exchange reference rate for the relevant currency pair on the company’s first trading day (https://www.federalreserve.gov/releases/h10/). If no such rate is available for the relevant trading day, the most recent previously published rate will be used. If the relevant currency is not listed, another credible exchange rate source will be used.

A listed company may resolve to "No" as soon as it becomes unable to complete an IPO, including due to acquisition, merger, or absorption by an entity that is already publicly traded.

In the event of an interruption in the course of the normal trading session on the respective companies’ first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.

Results from the "Rank" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the style control off will be used to resolve this market.

Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “xAI”). This market will resolve based on the company that occupies first place under this ranking system.

The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and resolve based on the first check after it becomes available.

Will OpenAI's valuation hit __ by July 31?

This market will resolve to “Yes” if OpenAI makes a new frontier model available to the general public by the specified date (ET). Otherwise, this market will resolve to “No”.

For this market to resolve to “Yes”, OpenAI’s new frontier model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be clearly defined and publicly announced by OpenAI as being accessible to the general public.

A frontier model refers to a newly released OpenAI model that OpenAI describes as one of its most capable or next-generation, general-purpose flagship models.

Qualifying new frontier models include successors to existing frontier models, such as GPT 5.2, which could succeed GPT 5.1 in the same way that GPT 5.1 succeeded GPT 5. Models focused on a specific task such as image generation or which are versions of a previous model optimized for a specific task (i.e. GPT 5.1-codex) or for cost-efficiency (i.e. GPT-5 mini) will not count.

Qualifying frontier models which are separate from the OpenAI GPT series will count. A qualifying new model from OpenAI’s o-series (i.e. o1, o3) will count.

The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.

Otherwise, this market will resolve to "No".

Results from the "Score" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with style control off will be used to resolve this market.

If no qualifying score for the specified model is available on the Arena.AI Leaderboard at 12:00 PM ET following the date of the release, this market will resolve based on the first subsequent instance at which such a score becomes available on the leaderboard. If no qualifying score becomes available by the end of the seventh day following the day of the model’s release, or if no qualifying model release occurs by December 31, 2026, 11:59 PM ET, this market will resolve to "No".

If multiple models are released on the same calendar date or if multiple variants of the specified model appear on the Arena.AI Leaderboard at the relevant check time (e.g., base, “Thinking,” or “Instant”), the highest-scoring variant will be used for resolution.

A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be either clearly defined and publicly announced as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within the company’s official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.

The resolution source for this market is the Chatbot Arena LLM Leaderboard found at arena.ai/leaderboard/text. If this resolution source is unavailable at 12:00 PM ET following the date of the release, this market will resolve based on the first subsequent instance at which such a score becomes available on the leaderboard.

3rd largest private company end of July?

On June 16, 2026, rumors regarding OpenAI's next-generation audio model named GPT-Bidi-1 surfaced. You can read more about that here: https://www.testingcatalog.com/openai-prepares-major-chatgpt-voice-upgrade-with-gpt-bidi-1/.

This market will resolve to "Yes" if OpenAI makes a qualifying GPT “Bidi” or “Bdi” next-generation audio/voice model for ChatGPT available to the general public by the specified date (ET). Otherwise, this market will resolve to “No”.

Any GPT model whose official name includes “Bidi” or “Bdi” will qualify. A differently named OpenAI voice/audio model may also qualify if a consensus of credible reporting identifies it as the rumored model referenced above. Other GPT releases will not qualify.

A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be either clearly defined and publicly announced by OpenAI as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.

The primary resolution source for this market will be official information from OpenAI; however, a consensus of credible reporting will also be used.

GPT-Bidi-1 released by...?

This market will resolve to “Yes” if credible reporting confirms that any entity enters into an agreement to acquire OpenAI (or the nonprofit that controls OpenAI) by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.

Mergers where OpenAI is subsumed by another entity will count toward a "Yes" resolution.

An announced agreement between OpenAI and an acquiring entity will qualify for a “Yes” resolution, regardless of whether the acquisition is ultimately completed.

The primary resolution source for this market is official information from Sam Altman and/or OpenAI however a consensus of credible reporting will also be used.

If no company's model reaches 1550+ Arena Score by the specified time, this market will resolve to "None in 2026".

If the first model to reach a 1550+ Arena Score belongs to any company other than the listed ones, this market will be resolved to "Other".

The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/.
