Planner reasoning

This is a Polymarket question about whether any Moonshot Kimi model reaches ≥50% HLE accuracy on the official leaderboard by end of 2026. The key drivers are the current best Kimi score, the overall frontier trajectory on HLE (top models globally), whether the agi.safe.ai leaderboard is actively updated with Kimi entries, and whether tool-augmented scores count. I'll anchor on the Polymarket price, search news for latest Kimi/HLE benchmark results, and triangulate with related markets on other HLE thresholds and rival labs.

# Current state Resolution hinges on the official agi.safe.ai HLE leaderboard listing a Moonshot Kimi model at ≥50% "HLE Accuracy" by Dec 31, 2026. No research source directly confirms whether Kimi models currently appear on agi.safe.ai itself; all figures found come from Moonshot's own blog and third-party trackers (Artificial Analysis, llm-stats, benchlm), which is a key ambiguity. Self-reported Kimi HLE numbers have historically run ~2x higher than independently verified figures, and a later 50.2% figure for K2.5 traces to a single low-reliability secondary source (codecademy.com), not the resolution source. # Timeline of key events - 2025-01: HLE benchmark launches; frontier scores near ~9% (code_execution analysis). - 2025-11: Kimi K2 Thinking released; Moonshot self-reports 44.9% HLE "with tools" (search/python/web-browsing), claimed SOTA at the time (confirmed — kimi.ai blog). - 2025-11-09: Independent trackers report much lower Kimi scores: Artificial Analysis measures 22.3% (no tools); Zvi Mowshowitz cites 23.9% (confirmed — artificialanalysis.ai, thezvi.substack.com). - 2026-01-27: Kimi K2.5 released (1T-param, "Agent Swarm" multimodal model); one secondary source claims 50.2% HLE (reported, single low-confidence source — codecademy.com). - ~2026-04: Kimi K2.6 released (reported — mysummit.school). - 2026-mid: Kimi K2.7-Code released (reported — mysummit.school). - 2026-07-16: Kimi K3 released (2.8T-param MoE, largest open-weights model; ranked 2nd of 47 models in independent testing behind GPT-5.6 Sol) (confirmed release, benchmark ranking reported — Wikipedia/mysummit.school). - Ongoing (as of research date): Third-party leaderboards (Artificial Analysis, llm-stats, benchlm) show top HLE scores 55–65%, led by Anthropic (Claude Fable 5: 55.5%, Opus 5: 54.9%) and OpenAI; none list a verified Kimi entry ≥50% (reported). # Event Will any Moonshot Kimi model reach ≥50% HLE Accuracy on the official agi.safe.ai leaderboard by Dec 31, 2026? # Outcomes to forecast - Yes - No # Kalshi market anchor No direct kalshi_direct data returned; the only same-ticker market data available is from Polymarket: current price 45% ("Yes"), down sharply from a 7-day high (7d change -11.5%, 30d change -3.0%), range 24.5%–60.5% over 41 days, total volume ~$15,161. This is the best available consensus anchor and shows recent bearish momentum after an earlier peak near 60%. # Sub-question answers 1. **Highest Kimi HLE score to date / on official leaderboard?** Self-reported: K2 Thinking 44.9% (with tools, Nov 2025); independently measured only 22.3–23.9%. A later, unverified claim puts K2.5 at 50.2% (Jan 2026, single low-reliability source). No confirmation these appear on agi.safe.ai itself — [kimi.ai, artificialanalysis.ai, thezvi.substack.com, codecademy.com]. 2. **Cross-lab SOTA and pace?** Current SOTA per Artificial Analysis is Claude Fable 5 (55.5%), Opus 5 (54.9%); frontier tool-augmented scores rose from ~9% (Jan 2025) to ~44.5% (Nov 2025), ~3.55pp/month, with likely deceleration afterward [artificialanalysis.ai, code_execution]. 3. **Tool augmentation?** Yes — Moonshot's reported 44.9% explicitly used search/python/web tools. Unclear whether the official leaderboard labels such agentic scores as canonical "HLE Accuracy" — unresolved ambiguity [kimi.ai]. 4. **Is agi.safe.ai actively listing Kimi?** Not directly confirmed by research; only third-party trackers were checked, none showing a Kimi entry ≥50%. Risk exists that Kimi scores may not be promptly/officially listed — a structural gap in evidence. 5. **Future Kimi releases in 2026?** Confirmed cadence: K2.5 (Jan), K2.6 (~Apr), K2.7-Code, K3 (Jul, 2.8T params, 2nd of 47 in independent testing) — Moonshot maintains ~quarterly release cadence with large jumps [Wikipedia, mysummit.school]. 6. **Gap to 50% and required pace?** From independently-verified baseline (~22–24%), gap is ~26–28pp, requiring faster-than-historical no-tool growth (~1.6pp/month, insufficient). From self-reported tool-augmented baseline (~44.9%), gap is only ~5pp, achievable within one release cycle given historical 10–15pp jumps between Kimi generations [code_execution]. # Key facts (high-confidence, factual) 1. [kimi.ai] K2 Thinking self-reported 44.9% HLE with tools (Nov 2025). 2. [artificialanalysis.ai] Independent verification of K2 Thinking: 22.3% (no tools). 3. [Wikipedia] Kimi K3 (July 2026) is a 2.8T-param model, largest open-weights model to date. 4. [artificialanalysis.ai] Current cross-lab SOTA (non-Kimi) ~55.5% (Claude Fable 5). 5. [mysummit.school] K3 ranked 2nd of 47 models in independent testing (source reliability moderate/unverified). # Cross-market signals - Polymarket (same ticker): 45% Yes, down from 60.5% high, trending down. - No Kalshi-specific or Polymarket-related HLE/Kimi markets found (only an unrelated esports "HLE" match). - No sportsbook signal available (not applicable). # Analyst opinions and speculation - Zvi Mowshowitz and Artificial Analysis flag a pattern of Moonshot overstating HLE results by ~2x versus independent verification. - code_execution model: point estimate ~55–65% probability of Yes if tool-augmented scores count as the resolving metric; drops to ~20–30% if strict text-only scoring is enforced. # Directional lean per outcome - **Yes**: Self-reported trajectory (44.9%→claimed 50.2%) already near/over threshold; rapid Moonshot release cadence (K2.5/K2.6/K2.7/K3) and industry-wide upward trend support crossing 50% under tool-augmented framing. - **No**: Independent/official verification consistently ~2x lower than self-reports; no third-party leaderboard (Artificial Analysis, llm-stats, benchlm) currently shows any Kimi model ≥50%; unclear if agi.safe.ai lists Kimi at all; Polymarket pricing has been falling toward 45%, suggesting market skepticism. # Gaps / unknowns - No direct check of agi.safe.ai leaderboard content for Kimi models. - Reliability of the 50.2% K2.5 claim (single tertiary source) is low. - Whether official leaderboard would classify tool-augmented scores as "HLE Accuracy" per market rules is unresolved. # Calibration anchors - Polymarket same-ticker price: 45% Yes (recent high 60.5%, declining). - Historical precedent: self-reported AI benchmark claims from Chinese labs have often been ~1.5–2x higher than independently verified figures (K2 Thinking case).

1. Both forecasters converge on identical 0.42/0.58 outputs despite ostensibly independent reasoning, and neither explicitly grapples with the compounding effect of multiple independent uncertainties (whether Kimi is even listed on agi.safe.ai AND whether tool-augmented scores count AND whether the 50.2% claim is real) — stacking these should push probability lower than a single "modest adjustment" from the anchor suggests. 2. Neither forecast adequately addresses the structural gap flagged in the brief: "No confirmation these appear on agi.safe.ai itself" — if Kimi isn't even listed on the resolution source, this is arguably a near-automatic No regardless of actual score, and this binary listing risk deserves more explicit weight than a marginal haircut. 3. Both anchor heavily on Polymarket's 45% while treating it as a stable consensus, but the brief notes it's "down sharply from a 7-day high" with "recent bearish momentum after an earlier peak near 60%" — this trend could reflect the market resolving exactly the ambiguity (tool-augmented vs. text-only, listing status) that both forecasters flag as unresolved, suggesting the trend itself is informative and should pull probability further down rather than just anchoring near the current point price. 4. The code_execution model's bimodal estimate (55-65% if tool-augmented counts vs. 20-30% if strict text-only) is mentioned in the brief but neither forecaster explicitly weights these two scenarios or states a probability for which resolution standard is more likely — this is a critical missing sub-calculation that could materially shift the final number in either direction. 5. Neither forecast discusses the low reliability of the K2.5 50.2% source (single codecademy.com citation) with appropriate skepticism-adjusted weight — both treat it as a soft positive signal for Yes, but given Moonshot's established 2x self-report inflation pattern, a claimed 50.2% likely implies a true/verified score closer to 25-30%, which should be a stronger bearish signal than either forecast reflects. 6. Neither considers the tail scenario where K3 (2.8T params, "2nd of 47 models") could independently push scores well past 50% by year-end given its strong ranking, nor the opposite tail where agi.safe.ai simply never lists any Kimi model at all (making the question resolve No by default) — both tails are underexplored despite being flagged in the sub-question answers.

37% (50% confidence)

Yes: 37% No: 63%

Both forecasts landed at 0.42, but the critique correctly identifies that multiple independent bearish factors compound: no confirmation Kimi appears on the resolution source (agi.safe.ai) at all, unresolved whether tool-augmented scores count as canonical 'HLE Accuracy', and Moonshot's documented ~2x self-report inflation (verified 22-24% vs claimed 44.9%) which implies the single-source 50.2% K2.5 claim likely reflects a true verified score far below threshold. Critically, as of mid-to-late 2026 no checked third-party leaderboard shows any Kimi entry ≥50% despite K2.5, K2.6, K2.7 and K3 having already shipped — this is late-cycle evidence, not just early-year uncertainty. The K3 tail (2nd of 47 in independent testing) and remaining ~5 months keep Yes meaningfully alive, and the declining Polymarket price (60%→45%) suggests the market itself is absorbing these same negatives. I move modestly below both forecasts and the anchor to 0.37 Yes.
