This is a Polymarket question about whether OpenAI's forthcoming 'Astra' model debuts on the arena.ai text leaderboard (no style control) at ≥1490. The key drivers are (a) the current top-of-leaderboard scores and their recent trajectory, (b) how big a jump recent frontier debuts have produced, and (c) whether Astra even appears on the leaderboard before Dec 31, 2026 (a non-appearance resolves No). Market price plus sibling threshold markets in the same event series give an implied distribution over the debut score.

# Current state Astra has not been released, has no confirmed public date, and has never appeared on the Arena.ai leaderboard (no AutoEval or full listing found as of mid-August 2026). OpenAI paused parts of internal Astra work over cybersecurity ("Critical" capability) concerns (Axios, Aug 7; CNBC, Aug 10), and reporting suggests a ~30-day federal AI-model review could push any public debut to September 2026 or later. The current Arena Overall (no style control) frontier sits in a tightly clustered 1500–1525 range across Claude Fable 5 / Opus 4.7-4.8 / Gemini 3.1 Pro / GPT-5.5 Pro, per conflicting aggregator snapshots (not the official leaderboard itself). # Timeline of key events - 2025-11-18: Gemini 3 Pro debuts at 1501 Elo, first model over 1500; Grok-4.1-thinking debuts same day at 1484 (confirmed, VentureBeat/Google blog). - 2026-02-26 (snapshot): Opus 4.6/4.6-Thinking tie #1 at 1503; Gemini 3.1 Pro Preview #3 at 1500; Grok-4.20-beta1 #4 at 1495; GPT-5.2 #6 at 1481 (reported, buildmvpfast.com — third-party aggregator, not primary leaderboard). - 2026-07-01/07-12: Claude Fable 5 restored to #1 and re-baselined to ~1525 (reported, localaimaster.com). - 2026-07-19: Alibaba previews Qwen3.8, claims #2 behind Claude Fable 5 (reported, SiliconAngle). - 2026-07-24: Claude Opus 5 tops a separate Fullstack Code Arena (1699 on a different scale) — not the Overall Text leaderboard (confirmed for that sub-arena only). - 2026-08-01: OpenAI publicly teases "Astra" as its "next major model" inside a math-proofs blog post (confirmed, OpenAI/Bleepingcomputer/Gizmodo). - 2026-08-07/08: Axios/Medium report internal evals flagged possible "Critical" cyber-capability risk; OpenAI pauses parts of Astra work, tightens controls (reported, CNBC, Times of India, multiple wire re-runs). - 2026-08-10: Altman says Astra will eventually be "generally available" but cyber capabilities need more safety work (reported, bravenewcoin.com). - Unverified: leaker claims Astra/"Mewfour" could ship "next week" (rumored, single X source, kimmonismus); codenames "Zinc"/"Magnesium" spotted in Design Arena, unconfirmed (rumored). # Event Will OpenAI's Astra model, when it first appears on the Arena.ai Text Overall (no style control) leaderboard, debut with a score ≥1490? # Outcomes to forecast Yes / No # Kalshi market anchor No kalshi_direct data was returned for this ticker (despite the "Kalshi" framing, the raw tool that matched this exact ticker was **polymarket_direct**). Treating that as the best available direct-market anchor: current YES-equivalent price **36.5%**, down sharply from a 62% high over the past 30 days (-25.5pp both 7d and 30d), range 30.5%–62%, thin volume (~$15.2K total, only 4 data points) — a fast-declining, illiquid market, consistent with recent safety-pause/delay news dampening near-term debut expectations. # Sub-question answers 1. **Current #1 score/model** — Conflicting aggregator snapshots (not the primary source) put #1 around 1503–1525 Elo (Claude Fable 5 or Opus 4.6/4.8 depending on source/date); no single authoritative live read was captured [claude_news, aggregator sites]. 2. **Recent frontier debut scores** — Gemini 3 Pro: 1501 (first over 1500, Nov 2025, confirmed); Grok-4.1-thinking: 1484 same day; Gemini 3.1 Pro: ~1500 tied #1; Grok-4.20-beta1: 1495; GPT-5.2: 1481. Jumps over prior #1 ranged roughly 6–40 pts historically per code_execution's reconstructed distribution (not sourced-exact, flagged as illustrative). 3. **Astra release status** — Not released; no Arena appearance; safety pause and possible ~30-day federal review push earliest plausible debut to September 2026+ [Axios/CNBC/howtouseastra.com]. No confirmed final name (GPT-5.7/GPT-6/Astra) [Bleepingcomputer]. 4. **Sibling Polymarket ladder** — A ≥1480 sibling market exists implying meaningful uncertainty at even lower thresholds; code_execution's illustrative ladder (unsourced) shows a monotonic, arbitrage-free survival curve from 0.93 (≥1450) to 0.04 (≥1520), market-implied P(≥1490)≈0.41. 5. **Trend vs. threshold** — code_execution's reconstructed 12-month drift is ~+9.5 Elo/month; current #1 ~1477 (per that reconstruction) implies Astra needs only a modest ~+13 pt jump to hit 1490, below the median historical debut jump (~19 pts) — this analysis is explicitly labeled illustrative/reconstructed, not verified against real leaderboard data. 6. **P(no qualifying appearance by Dec 31, 2026)** — Not directly quantified; given the safety pause, undecided naming, and pending federal review, non-trivial risk (research suggests but does not size) that Astra slips past year-end or lands under a different qualifying name/AutoEval-only status. # Key facts (high-confidence, factual) 1. [OpenAI/Bleepingcomputer] Astra publicly teased Aug 1, 2026 as "next major model," unreleased. 2. [CNBC/Axios] OpenAI paused parts of Astra work over possible "Critical" cyber capability, Aug 7-10, 2026. 3. [VentureBeat/Google] Gemini 3 Pro debuted at 1501, first model >1500 (Nov 2025). 4. [Bleepingcomputer] Final Astra branding (GPT-5.7/6/Astra) undecided. 5. [Polymarket] ≥1480 sibling market exists, implying pricing uncertainty at multiple thresholds. # Cross-market signals - Kalshi related: No direct Astra/Arena Kalshi market found; adjacent OpenAI-structural markets (IPO order, sector classification) unrelated to score. - Polymarket (this exact market): 36.5%, falling fast from 62% high. - Sportsbook implied: N/A. # Analyst opinions and speculation - code_execution model (self-flagged illustrative/reconstructed, NOT sourced real data) estimates P(Yes)≈0.55-0.71 based on hypothetical jump distributions — treat with heavy discount given explicit disclaimer of non-real data. - Rumors (single-source) suggest imminent release ("next week"), unverified. - Analysts widely cite safety pause + federal review as delay risk, weighing toward later/lower-confidence debut. # Directional lean per outcome - **Yes (≥1490):** Frontier cluster already sits 1495-1525; if Astra is genuinely "next major model," a debut in/above that band is plausible historically. Opposing: safety pause could mean a hobbled/limited initial release, uncertain scale, and market pricing has fallen hard to 36.5%. - **No (<1490 or no debut by Dec 31):** Falling Polymarket price, safety pause, undecided branding, possible federal review delay all support No/non-appearance. Sibling ≥1480 market suggests real doubt even at lower thresholds. # Gaps / unknowns - No live, verified read of the actual arena.ai leaderboard (all cited scores are third-party aggregators, sometimes conflicting). - No confirmed Astra release date or scale. - code_execution analysis is explicitly synthetic/illustrative — not real historical data. - No Kalshi-direct price was actually retrieved despite ticker. # Calibration anchors - Polymarket (proxy anchor): 36.5%, down from 62% (30d). - Precedent: Gemini 3 Pro debuted +~1 pt above prior #1 (1500→1501); Grok-4.1 debuted below new #1. Debuts do not reliably clear existing frontier by wide margins.

1. Both forecasts converge on 0.40 almost mechanically toward the Polymarket anchor, but neither explicitly separates the two very different sub-events (P(no qualifying debut by Dec 31) vs. P(score≥1490 | debut)) with distinct numeric estimates before blending — Forecast 1 gestures at "55-65%" and "75-85%" but then arbitrarily shades to 36.5% without showing the math reconciling ~0.45 implied vs. 0.365 final, understating how much weight is being placed on the market price itself rather than the sub-question decomposition. 2. Neither forecast interrogates why the Polymarket price fell 25.5pp in 30 days (62%→36.5%) — this could reflect genuine new information (the Aug 7-10 safety pause) or simply thin/illiquid trading (~$15.2K, 4 data points) subject to noise or a single large trade; treating it as a reliable "true" market signal versus a fragile, manipulable one is a live gap. 3. Both forecasts underweight the "wrong name/AutoEval-only" resolution risk flagged in the brief (sub-question 6 and fact 4: branding could be GPT-5.7/GPT-6 rather than "Astra," or it could appear only in AutoEval, not the full Overall no-style-control leaderboard) — this is a distinct path to "No" beyond simple delay, and neither rationale explicitly sizes this scenario separately from the timing/pause risk. 4. Historical precedent citation is inconsistent between the two: Forecast 1 lists GPT-5.2 at 1481 as evidence debuts "don't reliably clear," but the brief's own sub-question 2 shows GPT-5.2 debuted at 1481 while Grok-4.20-beta1 hit 1495 — both forecasts cherry-pick from a small, noisy n=5ish historical sample without acknowledging how thin this reference class is or how OpenAI's own past debuts (not just competitors') might differ systematically as a base rate. 5. Neither forecast addresses the tail scenario where OpenAI, given the "Critical" cyber-capability flag, releases a deliberately nerfed/limited version of Astra specifically to avoid triggering additional safety scrutiny — this could produce a real Arena debut that undershoots 1490 not because of raw capability but because of intentional capability throttling, a distinct causal mechanism from mere delay. 6. The synthetic/illustrative code_execution estimates (P≈0.55-0.71, and the "only ~13pt jump needed" framing) are explicitly flagged in the brief as unverified reconstructions, yet both forecasts implicitly lean on this framing (frontier "already sits 1495-1525," modest jump needed) without adequately discounting that this reconstructed baseline (~1477 for #1) conflicts with the aggregator-sourced #1 figures of 1503-1525 — a large enough discrepancy (near 30-50 pts) that the "modest jump" narrative may be substantially overstated.

34% (44% confidence)

Yes: 34% No: 66%

Decomposing explicitly: P(a qualifying 'Astra' debut on the Arena Text Overall (no style control) board within the resolution window) is roughly 0.45–0.55 given the Aug 7-10 'Critical' cyber-capability pause, a possible ~30-day federal review pushing launch to September+, undecided branding (GPT-5.7/GPT-6 vs. Astra), and the distinct risk of AutoEval-only or delayed full listing; P(score ≥1490 | qualifying debut) is high but not certain, ~0.75–0.85, since the frontier cluster sits ~1495–1525 yet recent flagship debuts (GPT-5.2 at 1481, Grok-4.1 at 1484) show major models can land below the threshold, and a deliberately throttled release to limit cyber-risk exposure is a live mechanism. That product lands near 0.38–0.42, but the critique's point 3 (naming/AutoEval resolution risk) and point 5 (intentional capability limiting) are genuine unpriced No paths that both forecasters glossed, pulling me slightly below their 0.40. The Polymarket proxy at 36.5% is thin and volatile (~$15K, 4 points, -25.5pp in 30d) so it deserves only moderate weight, but it moved on real news rather than noise alone, which corroborates the downward pull. I also discount the synthetic code_execution 'only +13 pts needed' framing, whose ~1477 baseline conflicts by 25–50 pts with aggregator reads of the current #1.
