All resolved official results 155 resolved rounds 1020 scored results Median confidence 0.57 Resolved history

High-confidence model calls have underperformed lower-confidence calls

Across resolved official results, submissions at or above the median confidence of 0.57 averaged -0.06%, while lower-confidence submissions averaged +0.23%.

Confidence is the model's own 0-1 self-reported confidence at submission time, compared with later realized returns.

AI consensus portfolio scored 2.8 versus the oracle

If the monthly model allocations were averaged into one consensus portfolio, it returned +4.30% versus -2.28% for the S&P 500 and +152.31% for the hindsight best asset.

Consensus means the average of model allocations in the same round. CapitalBench Score compares that return with the hindsight-best eligible asset for that exact scoring window.

The best scored asset returned +152.31%, the worst returned -20.98%, and +48.57% of the universe was positive. The S&P 500 ranked 48 out of 70 options.

Asset dispersion is the gap between the best and worst eligible assets in the same round. Wider dispersion makes missed allocation choices more costly.

Gemini 3.1 Pro's result was driven by US Dividend Equities

In the latest monthly result, US Dividend Equities contributed +3.40% to Gemini 3.1 Pro's portfolio. No holding detracted; the smallest positive contribution came from US Small-Cap Value at +0.50%.

Attribution multiplies each frozen holding's weight by its asset return to show what helped or hurt the model portfolio.

How Insights Are Produced

Deterministic calculations are the source of truth. LLM-assisted wording can polish selected titles and summaries, but it cannot change calculations, evidence links, round context, or benchmark facts.

Latest generation: Nov 4, 2026, 11:01 AM UTC

  1. 1 Build the input packet

    Collect public rounds, official portfolios, results, live marks, asset risk ratings, and benchmark sets.

  2. 2 Run deterministic math

    Calculate consensus performance, benchmark difficulty, market-environment results, risk posture, similarity, attribution, and live paths.

  3. 3 Attach evidence

    Every insight links back to round pages, leaderboard pages, scoring files, or methodology pages.

  4. 4 Validate before publishing

    The feed must pass schema checks before the website and API expose it.
