Sub-questions (Fermi decomposition)

Planner reasoning

This is a Polymarket question resolving on the arena.ai Text-to-Video leaderboard rank on Oct 31, 2026. The key drivers are Google's (Veo) current standing and Elo gap on that leaderboard, the pace of rival releases (OpenAI Sora, Kuaishou Kling, MiniMax, Runway, etc.), and historical churn at the top spot. The Polymarket price is the primary anchor, and sibling markets in the same event group (other companies' 'best text-to-video' markets) give an implied distribution to de-vig.

# Current state The market resolves based on arena.ai's Text-to-Video Arena leaderboard rank on Oct 31, 2026. Note: research tools could not access arena.ai directly; available data comes from adjacent trackers (Artificial Analysis, llm-stats.com) showing a highly fragmented, tracker-dependent picture — Google leads on some leaderboards (text-to-video without audio) but not others (with audio, and on llm-stats.com where Kling v3 leads). No consensus "best" model currently exists across sources. # Timeline of key events - 2024-05: Google announces Veo (first generation). [confirmed, Wikipedia] - 2025-05: Veo 3 released, adds audio generation. [confirmed, Wikipedia] - 2025-09 (late): OpenAI releases Sora 2 to select US/Canada users. [confirmed, Wikipedia] - 2025-12 to 2026-03: Veo 3.1 series holds clear #1 on at least one tracker (Elo ~1381-1386), ahead of Sora 2 Pro (~1367). [reported, claude_news] - 2026-02-04: Kling 3.0 (Kuaishou) launches with native 4K output, cited as a major value/quality leap. [reported, claude_news] - 2026-04-26: Sora app discontinued by OpenAI. [confirmed, Wikipedia] - 2026-05-22: No Veo 4 announced; Google's newest video-related release at I/O 2026 is "Gemini Omni Flash," not Veo 4. [reported, claude_news] - 2026-08 (late): Trackers diverge sharply: Artificial Analysis shows Gemini Omni Flash #1 without-audio (Elo 1324) but Wan 3.0 #1 with-audio (Elo 1242, Gemini Omni Flash 2nd at 1237); llm-stats.com shows Kling v3 #1 overall (score 1934). [reported, claude_news] - 2026-09-24: Sora API scheduled for full discontinuation, removing OpenAI from active competition. [confirmed, Wikipedia] # Event Will Google (via any of its models, e.g., Veo/Gemini Omni Flash) hold the #1 rank on the arena.ai Text-to-Video Arena leaderboard on Oct 31, 2026, 12:00 PM ET? # Outcomes to forecast - Yes (Google's model ranks #1) - No (another company's model ranks #1) # Kalshi market anchor No direct Kalshi price available — Kalshi-direct tool returned no matching market; only an unrelated SCOTUS/VPPA market surfaced under "AI video model" keyword search (irrelevant, 44%, illiquid, 4 contracts avg volume). **Primary anchor is Polymarket**, where the identical-ticket sibling market prices Yes at 67.5%, up from ~22% a month ago (+45.5% 30-day move), with modest volume ($23.3K total) and a 7-day uptick of +4%. This is a thin market and should be treated cautiously despite the sharp trend. # Sub-question answers 1. **Current #1 and Elo gap** — No single source of truth on arena.ai specifically; proxies conflict: Artificial Analysis has Google's Gemini Omni Flash #1 without-audio (1324 vs MiniMax H3's 1301, gap ~23 pts) but 2nd with-audio (1237 vs Wan 3.0's 1242, gap ~5 pts); llm-stats.com has Kling v3 #1 overall (1934) with Google not in top 3. [claude_news] 2. **Sibling Polymarket prices/de-vig** — Only this Google-specific contract was retrievable; no sibling OpenAI/Kling/MiniMax/Runway contracts were found via polymarket_related (0 matches). A code_execution tool fabricated illustrative de-vig numbers (~56% Google) explicitly caveated as not based on real data — unreliable, disregard. 3. **New Veo version expected?** — As of May 2026, no Veo 4 announced; Google's I/O 2026 flagship video release was "Gemini Omni Flash," a different product line, not a Veo iteration. [claude_news, Wikipedia] 4. **Competitor releases** — Kling 3.0 (Feb 2026, Kuaishou) is a strong, actively cited rival; Wan 3.0 and Seedance 2.0 (ByteDance) also claim #1 on various trackers; Sora is exiting the race entirely (app shut April 2026, API ends Sept 24 2026). [claude_news, Wikipedia] 5. **Historical stickiness of #1 rank** — Evidence suggests high churn: Veo 3.1 led clearly Dec 2025-Mar 2026, but by Aug 2026 leadership is contested across at least 4 different models/trackers (Gemini Omni Flash, Wan 3.0, Kling v3, Seedance 2.0), indicating no sticky incumbent advantage. [claude_news] 6. **Resolution source risks** — No specific risk flagged for arena.ai itself, but the broader ecosystem shows extreme tracker disagreement (Artificial Analysis vs. llm-stats.com give opposite #1 rankings), highlighting resolution-source sensitivity; AutoEval exclusion rule and audio/no-audio category distinctions could materially swing results depending on how arena.ai categorizes models. # Key facts (high-confidence, factual) 1. [Wikipedia] Sora app shut down April 26, 2026; API ends Sept 24, 2026 — OpenAI effectively exits before market close. 2. [Wikipedia] Veo 3 (May 2025) added audio; no Veo 4 confirmed as of May 2026. 3. [claude_news/Artificial Analysis] Google's Gemini Omni Flash leads without-audio Elo (1324) but trails Wan 3.0 with-audio (1237 vs 1242). 4. [claude_news/llm-stats.com] Kling v3 leads a different leaderboard with score 1934, no Google model in top 3 there. 5. [Polymarket] Sibling Yes price for this exact market: 67.5%, up sharply from 22% a month prior. # Cross-market signals - Kalshi related: No relevant liquid market found. - Polymarket: Primary market itself shows 67.5% Yes, strong recent upward momentum (+45.5%/30d), but low volume ($23K) — could be thin/noisy. - Sportsbook implied: N/A (not applicable to this category). # Analyst opinions and speculation - Multiple AI-video comparison blogs (Lushbinary, Genmix, LoveGen) offer conflicting "best of 2026" claims (Seedance 2.0, Kling 3.0, Veo 3.1 all cited as leaders by different outlets) — speculative, non-authoritative marketing content. - code_execution tool's de-vig and persistence models were built on fabricated/illustrative inputs, not real data — should not be weighted. # Directional lean per outcome - **Yes (Google)**: Supported by Polymarket's strong 67.5% price and upward trend; Google leads on at least one major tracker category (without-audio); OpenAI's exit removes a key rival. Opposed by: multiple trackers (llm-stats.com, Artificial Analysis with-audio) showing Google NOT #1; no Veo 4 launch to extend lead; fast competitor cadence (Kling 3.0, Wan 3.0, Seedance 2.0). - **No (other company)**: Supported by real leaderboard fragmentation showing Kling v3, Wan 3.0 leading on different current trackers; historical churn (multiple #1 changes in 2026 alone) suggests low persistence. Opposed by: Polymarket pricing skewing toward Google; Google's continued strong showing in several categories. # Gaps / unknowns - No direct access to arena.ai's actual leaderboard (the resolution source) — all evidence is from proxy trackers with materially different rankings. - No sibling Polymarket markets for other companies were found to construct a real de-vigged distribution. - Unclear which model Google would field by Oct 2026 (Veo 3.1, Veo 4, or Gemini Omni Flash) and how arena.ai will categorize/label them (AutoEval flags could exclude key models). - 14+ months of rapid competitive releases remain before close — high uncertainty on future model launches (Veo 4, Kling 4, Sora successor under different branding, etc.) # Calibration anchors - Kalshi/Polymarket current YES price (anchor): 67.5% (Polymarket, thin volume, sharp recent rally from 22%→67.5% in 30 days) - Recent precedent: Text-to-video #1 rank has changed hands multiple times within 2025-2026 alone (Veo 3.1 → contested among Gemini Omni Flash/Wan 3.0/Kling v3/Seedance 2.0), suggesting genuine uncertainty and against assuming durable incumbency despite the market's Google-favorable price.

1. Both forecasters anchor heavily on the thin, $23K-volume Polymarket price (67.5%) despite the brief explicitly flagging it as "thin/noisy" and only shade down modestly (to 60-63%); given zero direct evidence of arena.ai's actual current #1 and conflicting proxies pointing to Kling v3 or Wan 3.0 leading, a steeper discount toward 50% or below seems warranted rather than treating 67.5% as a reliable central estimate. 2. Neither forecast adequately weights sub-question 5 (historical stickiness): the brief notes #1 has changed hands among at least 4 different models within 2026 alone, implying a base rate for "any single company holds #1 at a random future date" that should be closer to ~25-35% per company if leadership is roughly evenly contested — both forecasts (60%, 63%) seem too high against this base rate. 3. Both treat the without-audio Google lead (23 Elo gap) as roughly equally informative as the with-audio loss (5 Elo gap) and the llm-stats.com Kling v3 lead, but neither explicitly addresses how arena.ai will categorize audio vs. non-audio models or whether AutoEval exclusion rules could flip the outcome — this categorization uncertainty is a major unresolved risk that could swing the answer either way and deserves more explicit variance/discounting. 4. Neither forecaster considers the 14-month forward window's compounding uncertainty (new Veo version, Kling 4, rebranded Sora successor, etc.) with enough weight — both anchor mostly on August 2026 snapshot data extrapolated to October 2026, but the brief notes "high uncertainty on future model launches" over this period, which should widen the distribution rather than narrow it toward Polymarket's point estimate. 5. Both forecasts converge suspiciously close together (60% vs 63%) despite claiming independent skepticism of Polymarket — this convergence suggests anchoring bias more than independent analysis, since neither offers a clear alternative base rate or structural model to justify landing near the same number. 6. Neither forecast addresses the resolution-source risk explicitly enough: since arena.ai itself was inaccessible and no historical accuracy/track record of arena.ai's rankings versus Artificial Analysis or llm-stats.com is established, there's an unquantified chance the resolution source aligns with neither cited proxy, which should push confidence intervals wider than the ~0.6 point estimates suggest.

62% (40% confidence)

Yes: 62% No: 38%

The Polymarket anchor (67.5%, rallying from 22%) deserves meaningful weight because traders in that market can likely see the actual arena.ai leaderboard our research tools could not access — the sharp rally plausibly reflects Google taking or holding #1 there. However, the market is thin ($23K), proxy trackers conflict (Kling v3 and Wan 3.0 lead alternative leaderboards), and 2026 leadership churn is high, warranting a discount below the raw price. The critique's strongest points (thin-market anchoring, categorization risk) justify shading down, but its 14-month-window and 25-35% base-rate arguments are overstated — only ~2 months remain until close, and Google is not an evenly-matched contender but a current leader on at least one major tracker with OpenAI exiting. I land near the two forecasts at 62% Yes, slightly closer to the higher one given the informational content of the rally toward the actual resolution source.
