GPT Astra 6.1+: HLE-Diamond Debut?

According to the latest prediction market data for the query “GPT Astra 6.1+: HLE-Diamond Debut?”, traders have formed a strong consensus.

Currently, 55%+ is dominating the market with an overwhelming 91% chance of winning. 60%+ follows in second place at 85.5%, while 65%+ sits in third with 57.5%. The betting volume for this specific market has already reached $99.9K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• 55%+ (91%): Currently commanding the highest probability, 55%+ is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 91¢, signaling a high degree of market conviction. This contract alone has generated $26.3K in volume.

🥈 Tier 2: The Primary Challengers

• 60%+ (85.5%): Positioned as the most viable alternative, 60%+ maintains a 85.5% chance of resolving true. Its “Buy Yes” shares currently trade at 86¢.
• 65%+ (57.5%): Sitting in third place with a 57.5% probability, the market shows measured skepticism toward 65%+, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes 70%+ (18%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like 70%+ are still attracting notable interest.

This market will resolve to "Yes" if the next OpenAI GPT Astra model (6.1+) 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 an OpenAI model designated as version 6.1 or higher that includes "Astra" in its name or model identifier, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. For example, GPT-6.1 Astra, Astra 6.1, or GPT Astra 7 would all qualify. GPT-6 Astra, including any rollout, promotion, Pro or Fast mode, or snapshot of it, will not qualify. Tier-labeled models such as GPT-5.6 Sol, GPT-5.6 Terra, or GPT-5.6 Luna and their successors, and task-specific or modality lines such as GPT-5.6-Cyber, Daybreak models, Codex, GPT Image, or Realtime models, will not qualify.

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".

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome 65%+ currently trades at 57.5%, but our AI places its Fair Value at just 40.3%. This creates a large negative EV Gap of -17.2%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies 55%+ as the premium value opportunity on the board. While the market only assigns it a 91% trading probability, our AI’s Fair Value assessment sits at 92% — yielding an impressive +1% EV Gap.
