1. [sq1 | web_search | STRONG cred 88 | DOWN | VERY_RECENT] As of ~Aug 13-14, 2026, docs.x.ai release notes show Grok 4.6 and 4.5 as latest entries, with no Grok 4.7 entry.
2. [sq1 | web_search | MODERATE cred 65 | DOWN | VERY_RECENT] Third-party trackers state xAI has published no model card, pricing, context window, or benchmarks for Grok 4.7, which remains unreleased.
3. [sq2 | web_search | STRONG cred 88 | UP | VERY_RECENT] Grok 4.6 was officially released on the xAI API around August 12, 2026, and documented on docs.x.ai with model ID and 500k context.
4. [sq2 | web_search | MODERATE cred 60 | UP | VERY_RECENT] Reporting describes xAI's current cadence (4.5 → 4.6 → 4.7 → Grok 5 by end-2026) as its most aggressive release sprint yet.
5. [sq3 | web_search | MODERATE cred 75 | UP | RECENT] Musk on July 24/28 and Aug 4 explicitly used the label 'Grok 4.7' for a 2.1-trillion-parameter successor to Grok 4.6.
6. [sq3 | web_search | STRONG cred 80 | NEUTRAL | RECENT] On SpaceX's Aug 4 Q2 earnings call Musk said Grok 4.7 would arrive three to four weeks after 4.6, implying roughly Sept 2–9, 2026.
7. [sq3 | web_search | WEAK cred 40 | UP | VERY_RECENT] One outlet reported an August 12 signal that 'narrows Grok 4.7's release window,' without a confirmed date.
8. [sq3 | web_search | MODERATE cred 65 | NEUTRAL | DATED] xAI's recent naming pattern has followed sequential .1 increments (4, 4.1, 4.5, 4.6) but also included variant labels like 'Fast'.
9. [sq4 | web_search | MODERATE cred 78 | UP | VERY_RECENT] Grok 4.6's docs.x.ai release-notes entry appeared essentially at launch, indicating xAI documents API model launches promptly.
10. [sq2 | code_execution | WEAK cred 35 | NEUTRAL | VERY_RECENT] Monte Carlo decomposition of ship-rate, label choice, and documentation probability yields mean 0.48 (q10-q90: 0.31-0.65).
11. [sq2 | article_search | WEAK cred 60 | NEUTRAL | RECENT] News coverage of xAI from May–Aug 2026 focused on lawsuits, data centers, and the SpaceX IPO, with no model-release schedule disruptions reported.
12. [sq3 | web_search | MODERATE cred 70 | DOWN | RECENT] Musk's original promise of 'Grok 4.6 in 2 weeks, 4.7 in 4 weeks' already slipped, with 4.6 arriving later than the stated 2-week window.

Information gaps:

  - No direct scrape/verification of docs.x.ai release notes at the resolution-relevant date
  - No evidence on whether xAI plans a 'Grok 4.7' vs jumping to Grok 5
  - No market/prediction-platform pricing for this question

Key uncertainties:
  - Whether the ~3-4 week post-4.6 window lands before or after Sept 5
  - Whether xAI keeps the '4.7' label or renames (e.g., 4.6 Fast, 5)
  - Typical Musk timeline slippage magnitude for model launches
  - Whether an app-only or preview release would appear in API release notes

## Question
Will Grok 4.7 appear on SpaceXAI's release notes before September 5, 2026?

## Description / Resolution Criteria
## Description
Elon Musk: [Grok 4.6 in 2 weeks and Grok 4.7 in 4 weeks](https://x.com/elonmusk/status/2080724087593226311)

`{"format": "bot_tournament_question", "info": {"hash_id": "0ffd0dfeab8e936f", "sheet_id": "159"}}`

## Resolution Criteria
This question resolves as **Yes** if a version of Grok that is specifically numbered 4.7 has any mention for any reason at SpaceXAI's [Release Notes](https://docs.x.ai/developers/release-notes) before September 5, 2026. If this does not occur for any reason, including that X AI changes its numbering scheme (such as skipping 4.7 or changing it to 4.70), this question resolves as **No**.

## Sub-question decomposition
- (w=0.30) Is a model specifically numbered 'Grok 4.7' already listed on xAI's release notes page (docs.x.ai/developers/release-notes) as of the research date?  — If it has already shipped, the question resolves YES immediately; this is the single highest-information check.
- (w=0.20) Will xAI ship at least one new Grok model of any name/version between now and September 5, 2026?  — Establishes the baseline shipping cadence; xAI ships frequently, so the binding constraint is naming, not activity.
- (w=0.35) Conditional on xAI shipping further 4.x-series updates before Sept 5, 2026, will the specific label '4.7' be used (rather than skipping to 4.8, 5, 'Fast', a codename, or a different scheme)?  — The core uncertainty: xAI has a history of irregular version naming (4.1, 4.1 Fast, 4.20-style jokes, jumping to Grok 5)
- (w=0.15) If a Grok 4.7 exists in any form (API, app, announcement), will it be documented on the official docs.x.ai release notes page before Sept 5, 2026?  — Resolution requires the specific release-notes page mention; consumer-app-only releases or delayed doc updates could blo

Combination rule: **weighted_average**

## Required pre-forecast walkthrough

Before giving probabilities, walk through these explicitly:
  (a) The time left until the question resolves.
  (b) The status quo outcome — what happens if nothing changes from today.
  (c) A brief scenario that results in NO.
  (d) A brief scenario that results in YES.

## Calibration guidance

- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.
