Alpha Arena Season 1.5 AI trading competition winner?

2025年12月3日

I’ve been following this competition obsessively—and after weeks of tracking pricing signals, outcome flows, and market positioning, my conclusion is clear: Season 1.5 is shaping up to be the most unpredictable and pivotal round in the evolution of AI-driven trading.

What’s happening right now is bigger than a leaderboard ranking. It’s evolving into a defining experiment for whether reasoning-heavy AI models can outperform tactical precision models in real financial markets, rather than the synthetic battlefield that was Season 1’s crypto perpetuals arena.

The market has shifted dramatically, the rulebook has changed, and the leaderboard hierarchy has been violently reset.

And based on everything I’ve analyzed through Powerdrill Bloom, the fight is converging into a narrow two-horse race.

A Three-Tier Probability Breakdown

Tier 1 — The Most Likely Winners (Combined 68% Probability)

Candidate

Probability

Thesis

GPT-5.1 (OpenAI)

35%

Rebuild narrative after Season 1 collapse + superior data infrastructure and execution advantages

Unknown

33%

Maximizing opacity advantage—uncounterable strategy due to zero public intelligence

Tier 2 — Dark Horse Contenders (~14% Combined)

Candidate

Thesis

DeepSeek + Qwen 3 Max

Outperformed in Season 1 crypto, but market signals indicate reduced adaptability to equities

Despite being dominant in the crypto environment, their probability curve implies structural disadvantages when transitioning to equity markets, where execution latency, order routing precision, and macro-driven volatility matter more than raw reasoning depth.

Tier 3 — Consensus Laggards (~18% Combined)

Candidates

Probability Per Model

Google Gemini, Anthropic, xAI, others

< 2–3% each

These models are perceived as fundamentally mismatched for the current rule environment—more research-style than execution-style.

Evidence Behind My Prediction

1. Crypto → Stocks Risk Regime Shock

The results from Season 1 exposed structural weaknesses:

  • Chinese models demonstrated resilient profit sustainability
    Qwen’s conservative stop-loss / take-profit discipline avoided wipeouts.

  • US models suffered catastrophic losses
    GPT-5’s -62.66% result suggests that high-complexity reasoning actually became a competitive disadvantage due to over-optimization and aggressive leverage utilization.

That performance collapse is the defining inflection point leading into Season 1.5.

The stock market requires different skill requirements:

  • Less sensitivity to microstructure prediction

  • Higher penalty for wrong macro timing

  • Risk management > reasoning complexity

This transition is the real storyline.

2. Operational Advantages for GPT-5.1

While Season 1 was disastrous for OpenAI, Season 1.5 offers meaningful improvements:

Structural Edge

Impact

Access to large-scale US equity data

Stronger predictive calibration

Institutional execution partnerships

Lower slippage, faster routing

Improved model iteration over Season 1 failures

Better risk discipline

This makes GPT-5.1 the most structurally advantaged public competitor.

Critical Uncertainties That Could Swing the Outcome

1. Market Regime Disruption Risk

Any major external shock (FOMC, tech rotation, geopolitical volatility) could invalidate all strategy assumptions.

If the competition timeline crosses December FOMC, volatility risk intensifies drastically.

2. Rules Still Undefined

The competition includes four modes:

  • Baseline

  • Monk

  • Situational Awareness

  • +1 undisclosed

Without knowing:

  • whether scores aggregate or weight by mode

  • or whether specialization beats generalization

DeepSeek/Qwen odds could spike if mode weighting favors niche strategy mastery.

This uncertainty is strategically massive.

How I’m Tracking This in Real Time

All of these probability distributions, regime-shift signals, and uncertainty modeling were synthesized through Powerdrill Bloom, which I use daily to analyze live prediction-market pricing, volatility scenarios, and model-based outcome curves.

If you want to explore these scenarios interactively, run your own probability trees, or model volatility breakpoints, you can do it directly inside Powerdrill Bloom—it’s exactly what I’m using to track this competition hour by hour.
