GPT Astra 6.1+: HLE-Diamond Debut?
Leaning No: the newest lineup updates still show no qualifying GPT Astra 6.1+ model on the HLE-Diamond chart, and October 21–26 reports suggest a GPT-6.1 Astra launch was delayed or canceled. Without a confirmed debut, the 55% threshold never gets tested.
Analysis
As of October 26, 2026, the visible OpenAI lineup still does not show a qualifying GPT Astra 6.1+ model on Humanity’s Last Exam, and no HLE-Diamond score is posted for one. The freshest reports point to GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna, not a qualifying Astra 6.1+ entry.
Arguments
For
- The event only needs one qualifying Astra 6.1+ model to appear with HLE-Diamond Accuracy of at least 55%.
- Frontier OpenAI models have enough capability that a 55% HLE-Diamond debut is plausible if Astra 6.1+ launches.
- The market has stayed strongly Yes, suggesting traders still expect a qualifying appearance before the deadline.
Against
- The latest evidence does not show any qualifying GPT Astra 6.1+ model on the chart yet.
- Coverage on October 21–26 points to GPT-6 Astra and GPT-6.1 Sol, which do not satisfy the market’s naming rule.
- Reports of a delayed or canceled GPT-6.1 Astra rollout reduce the chance of any qualifying debut happening soon.
Key drivers
- No qualifying GPT Astra 6.1+ model is currently visible on the official HLE results page.
- Recent reports specifically describe a GPT-6.1 Astra launch delay or cancellation, which weakens the debut case.
Risk factors
- OpenAI could still add a qualifying GPT Astra 6.1+ model later in the market window.
- If a qualifying score appears, the 55% bar may be reachable quickly for a frontier OpenAI model.
Scenarios
Best case
If a qualifying GPT Astra 6.1+ model is added to HLE-Diamond and posts at least 55% before the first-check window closes, Yes rises to about 98%.
Most likely
Most likely, OpenAI either adds a qualifying Astra 6.1+ model later or does not, and Yes ends up around 88% to 92%.
Worst case
If no qualifying GPT Astra 6.1+ model appears on HLE-Diamond by June 30, 2027, Yes falls to about 0%.

Next Prime Minister of Serbia?
AI57%MKT2%Edge+55Hidden GemVučić has a plausible path back to the premiership, but it still depends on the election result, coalition arithmetic, and whether he remains the governing bloc’s chosen nominee. I lean slightly toward Yes because of his institutional advantages and the market’s sustained confidence, but the outcome is still meaningfully uncertain.

Will Predict.fun launch a token by ___?
AI83%MKT97%Edge-14OvervaluedThe odds still look strongly tilted toward a token launch by November 30, 2026, but there is enough implementation uncertainty that I would price it a bit below the market. The most likely outcome is that Predict.fun does launch on time, though the lack of a formal date and conversion details keeps a meaningful no-risk tail.

Oscars 2027: Best Costume Design Nominations
AI79%MKT90%Edge-11OvervaluedThe Odyssey looks like a strong favorite to land a Best Costume Design nomination, with broad early consensus from forecasting panels and the kind of prestige profile that usually supports below-the-line recognition. The main reason to avoid assigning an even higher probability is that costume lineup outcomes can still shift as late-season contenders strengthen or campaign momentum changes.
