The Real Winner Behind Anthropic — NewsPicks on Jane Street and the AI Quant Structure

This NewsPicks episode names Jane Street as 2026's most lucrative 'secret company' in the AI industry. It sits behind the more visible names — Anthropic, OpenAI, NVIDIA, the neoclouds — and the first half of 2026 is when even US tech circles started discussing it openly.

The name sounds generic, like an ordinary street name, but it's the quant trading firm on Anthropic's cap table. The hosts open with a veteran-investor framing: 'Anthropic, NVIDIA, neoclouds — you all already know those.' The framework for the whole episode is that one layer above the visible AI companies sits a player that converts AI's accuracy gains into trading profit.

The core of Jane Street's business is estimating 'the correct price right now' at AGI-class precision. The closer their models get to AGI, the more clearly they see the gap between an ETF's theoretical value and its market value — and the whole gap is recoverable as profit.

This is not the high-frequency game of 'react fast, fire fast.' It's the inverse — invest time in finding the truly correct price, and earn outsized profit from the gap. Suspended securities, instruments distorted by war-driven price moves, FX exhibiting unusual divergence. The position is that you need every kind of noise and signal in the model to know the true price, and the target spans bonds and derivatives. Precision gained in AI research feeds directly into trading revenue.

The other principal is former OpenAI staffer Leopold Aschenbrenner. After being fired over a memo flagging Chinese security concerns, he published a Nostradamus-style essay called 'Situational Awareness' and launched an AI-focused investment fund under the same name.

The thesis: the algorithm problem is solved; the binding constraint going forward is power and infrastructure. Rather than VC, the fund targets public equities concentrated in power, batteries and data-center supply chains. Assets under management went from roughly $225 million in late 2024 to over $20 billion now — a hundredfold expansion. The structural detail is that Jane Street invests in this fund and in Anthropic itself, while Anthropic also invests in the Leopold fund. AI research labs and quant funds hold each other on their cap tables, and the chain of AI infrastructure investment closes into a single loop.
