State of AI · Public evidence through July 22, 2026

Hedge funds are building the research machine before the finance model.

Man AHL leads the disclosed agentic workflow. CFM owns the clearest narrow fine-tuning result. AQR-affiliated researchers have published the deepest language-model training program. Most competitors are still exposing the build layer through hiring.

4different leaders, depending on the criterion

01 · Competitive position

The public AI journey has two independent axes.

Moving right means more of the investment-research loop is disclosed. Moving up means stronger evidence that finance-specific language-model weights changed. Neither axis measures returns.

02 · The category leaders

There is no single leader because the market is solving four different problems.

Agentic workflow

Man AHL

AlphaGPT and AlphaTrend disclose the fullest hypothesis-to-code-to-evaluation loop.

No Man-trained finance LM disclosed.
Narrow fine-tuning

CFM

Compact financial NER fine-tuning improved reported F1 from 87.0% to 93.4%.

Extraction task, not investment reasoning.
LM training research

AQR-affiliated

Point-in-time models trained from scratch, with monthly checkpoints and LoRA instruction tuning.

Portfolio deployment is not public.
Investor deployment

Citadel

AI Assistant is described as used by nearly all equities investors.

“Trained on” does not establish changed weights.

03 · Evidence stack

The firms cluster by what they have chosen to disclose.

A filled cell means public evidence exists. It does not mean a competitor lacks an undisclosed capability.

Firm Talent AI runtime Agentic research Named deployment LM weights changed
Verified Directional / affiliated Hiring or infrastructure signal No public evidence found

04 · People and models

Public recruiting data reveals direction, not team size.

No audited firm publishes a complete count of AI employees. The defensible measures are a public minimum of named practitioners and the number of distinct AI role families observed. Current-role checks also prevent alumni evidence from being presented as current ownership.

Public AI talent signal

Named practitioners plus distinct AI/ML role families in the evidence set. The worker audit now covers research engineering, MLOps/HPC, investment engineering, GenAI integration, and quant software. This is a disclosure footprint, not headcount.

Verified finance-LM weight modification

Public minimum. “0 disclosed” is not evidence that no private model exists.

The strategic read

The moat is the testable research environment.

The strongest public precedent combines frontier reasoning, proprietary data and tools, code execution, institutional methodology, and hard evaluation gates. Smaller adapted models enter where a repeated task produces a measurable quality or cost advantage. The evidence does not support beginning with a giant proprietary “finance GPT.”

Decision

Build the research harness and trace every hypothesis, code artifact, data lineage record, rejection, and human override. Fine-tune only after those traces reveal a stable repeated task.
