Gemini Carbon: HLE-Diamond Debut? odds

On October 9, 2026, Business Insider reported that Google employees were internally testing a Gemini 4 model codenamed "Carbon," separate from the checkpoint later released as Gemini 4 Argon (https://www.businessinsider.com/google-employees-test-new-gemini-4-model-argon-barium-carbon-2026-10). This market will resolve to "Yes" if the Google "Carbon" model added to the Humanity's Last Exam results at https://agi.safe.ai/ has an HLE-Diamond Accuracy of at least the specified percentage at 12:00 PM ET on the calendar date following the date on which it first appears on the site. Otherwise, this market will resolve to "No". A qualifying model must be a Google AI model named "Carbon" (including variants or successor branding such as Gemini Carbon, Gemini 4 Carbon, or similar naming) or be confirmed to be the same model referenced in the report by Google or by a consensus of credible reporting. A model listed under any other name, including a new Gemini model (e.g., Gemini 4.1) or an update to Gemini 4 Argon, will qualify only if it is confirmed by June 30, 2027, 11:59 PM ET to be the same model previously codenamed "Carbon". Models merely derived from, distilled from, or incorporating improvements from Carbon will not qualify unless confirmed to be the same model. The percentage displayed as "HLE-Diamond Accuracy" for the model in its result card on the "AI Progress on HLE-Diamond" chart at https://agi.safe.ai/ will be used to resolve this market. This market will resolve solely based on the HLE-Diamond Accuracy, regardless of the model's Calibration Error, chart position, other configuration scores, any note that a score was computed on a sample of questions, or any underlying granular or unrounded data presented elsewhere. If the Center for AI Safety (CAIS), which maintains the official Humanity's Last Exam results, publishes a qualifying score (defined below) for the model, and the model has not been displayed on the chart by 11:59 PM ET on the third calendar day (ET) after the first such publication, that score will be used instead, rounded to one decimal place. If multiple qualifying scores for the model have been published by that time, the highest will be used. A qualifying score is one issued under CAIS's name (for example, on https://agi.safe.ai/, https://lastexam.ai/, or https://dashboard.safe.ai/, including jointly with Scale AI) that is clearly identified as overall accuracy on the full HLE-Diamond question set (1,000 questions, released September 22, 2026), without tools, at the reasoning setting labeled "high" in HLE-Diamond's main results. No score other than the chart value or a qualifying score will count, even if no qualifying score is published. This includes scores on the original Humanity's Last Exam or HLE-Rolling, "reasoning max" or "with tools" results, Reasoning or Knowledge partition scores, values available only through an API, data file, or page source, scores from Scale AI's separate leaderboards, other evaluators, or the model's developer, and any score where there is reasonable doubt that it meets the conditions above. A model first appears on the site on the earlier of the date (ET) it is first displayed on the chart and the date (ET) a qualifying score for it is first published. If the chart value is used, the check described in the first paragraph takes place at 12:00 PM ET on the calendar date following the model's first display on the chart; if a qualifying score is used, it takes place at the end of the three-day period described above. If multiple qualifying models are added to the Humanity's Last Exam results on the same calendar date (ET), the model with the highest HLE-Diamond Accuracy will be used for resolution. Models added to the results on the calendar date following the initial qualifying model's first appearance will not be considered. If a model is first added to the Humanity's Last Exam results but is subsequently removed and not re-added, such that no HLE-Diamond Accuracy for it is available under these rules at the time of the check, its appearance will not qualify as added to the Humanity's Last Exam results. A qualifying model must be newly added to the Humanity's Last Exam results. Whether the model was previously released, publicly accessible, in beta, or otherwise available before appearing on the site is irrelevant for this market. In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market. The primary resolution source for this market is the official Humanity's Last Exam website found at https://agi.safe.ai/. If this resolution source is unavailable at the time of the check, this market will resolve based on the first subsequent instance at which the model's HLE-Diamond Accuracy becomes available. If it remains unavailable through the end of the seventh day after the qualifying model first appears on the site or if no qualifying model is added by June 30, 2027, 11:59 PM ET, this market will resolve to "No".

This market will resolve according to the company which owns the model which has the highest arena rank based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on October 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market. Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score. 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 still 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 “SpaceXAI”). This market will resolve based on the company that occupies first place under this ranking. The resolution source for this market is the arena.ai Text Arena (Overall). If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve to "Other".

This market will resolve to "Yes" if Anthropic announces that it will file for bankruptcy or has filed for bankruptcy of any variety by the listed date, 11:59 PM ET. An announcement will suffice for a "Yes" resolution, regardless of if or when the actual filing occurs. The announcement must be made through any of their official or verified channels, as a recorded or written statement by their CEO, legal representation, or other individual or team which officially represents Anthropic. A definitive consensus of credible reporting may also be used. "Anthropic" refers to Anthropic, PBC, the parent company of the Anthropic group, or any other entity that is controlled by, or is under common control with, Anthropic, PBC and that holds, directly or indirectly, all or substantially all of Anthropic's business and assets at the time of the filing or announcement. Unless named above, foreign entities, financing entities, special purpose vehicles, and entities used to separate specific legal liabilities will not qualify, even if they meet that test. A filing for bankruptcy means a petition by an entity this market refers to (each, a "covered entity") under Chapter 7 or Chapter 11 of the United States Bankruptcy Code, or a bankruptcy case for a covered entity filed in a court outside the United States under that country's bankruptcy or insolvency law, including a court-appointed administration. A petition filed against a covered entity by its creditors will qualify only if the court enters an order for relief on that petition by the listed date. An announcement must state that a covered entity has decided to file for bankruptcy, or has filed for bankruptcy. Statements that the company is considering, exploring, or open to bankruptcy, or that bankruptcy is one of several options, will not qualify. A definitive consensus of credible reporting may be used to confirm that a qualifying announcement or filing occurred. Reports citing unnamed sources that a covered entity plans or is preparing to file will not qualify on their own. Once a qualifying filing or announcement occurs, this market will resolve to "Yes" even if the petition is later withdrawn, dismissed, or converted, or the company later reverses its decision. The following will not qualify on their own: a missed payment or other default on debt; a breach of a loan covenant; foreclosure or other enforcement action by creditors; a credit rating downgrade; a debt exchange or other restructuring agreed outside of court; the appointment of a receiver; and an assignment for the benefit of creditors. If a covered entity stops existing because of a merger or similar transaction, it will no longer be a covered entity. If, after the merger, no covered entity remains, this market will resolve to "No". If the transaction only changes a covered entity's name, state of incorporation, or legal form, or places a new holding company over the same business, the resulting entity will be treated as that covered entity. A filing occurs at the time recorded by the court. An announcement occurs at the time it is first published by a covered entity or its representative.
