$2B chasing Anthropic, $600M of OpenAI unsold: how secondary markets are repricing the AI race - Silicon Canals

The secondary market for private company shares doesn't just reflect investor sentiment -- it prices the future before the future arrives. And right now, that market is delivering a verdict on the AI race that should unsettle OpenAI's backers: Anthropic is being repriced as the preferred bet, while OpenAI, the category's supposed frontrunner, is experiencing a buyer drought. This isn't a temporary wobble in market sentiment. It's a fundamental repricing of which company the smart money believes will define the next era of AI -- and the divergence is accelerating.

As TechCrunch reported, sources familiar with secondary market trading described the current dynamic in stark terms, with Anthropic shares proving extremely difficult to source as sellers remain scarce.

The numbers crystallise how dramatic the split has become. According to Bloomberg, roughly $2 billion in ready-to-deploy capital is chasing Anthropic shares through secondary market platforms -- yet sellers are almost impossible to find. Meanwhile, an estimated $600 million worth of OpenAI shares that investors are actively trying to offload haven't found takers. OpenAI shares on the secondary market are trading at a meaningful discount to the company's most recent primary-round valuation. When one company has more capital than available shares and another has more shares than available capital, you're not looking at a sentiment blip. You're looking at the market redrawing its map of who wins.

Market observers attribute part of Anthropic's surge to a counterintuitive catalyst: the company's public standoff with the Department of Defense. What initially appeared to be a reputational risk became a differentiator. In a market where investors are increasingly pricing governance and positioning alongside raw technical capability, Anthropic's willingness to draw a public line amplified its brand as the "responsible AI" company -- and made it more distinct from OpenAI at precisely the moment investors are looking for differentiation.

The pricing signals from Wall Street reinforce this gap. Investment banks are charging significant carry fees for clients seeking Anthropic exposure, while some banks have begun offering OpenAI shares to high-net-worth clients with reduced or waived fees. When intermediaries waive their margin to move product, it tells you something about where real demand sits. The fee structure is the market's confession.

OpenAI has responded by attempting to tighten control over its secondary market. According to reports, OpenAI has warned investors to be cautious about unauthorized secondary market transactions and has established official channels through banks to combat high-fee broker activity. The company has established authorised channels through banks with no fees -- a move designed to counter the high-fee broker model, but one that also functions as an acknowledgment that secondary pricing has drifted from where the company wants it.

This is what a repricing looks like from the inside. When a company starts engineering its own secondary market infrastructure to prop up perceived demand, it's no longer just managing its cap table -- it's managing a narrative that the market has begun to reject.

Anthropic, which recently raised $30 billion at a $380 billion valuation, faces no such demand problem. When OpenAI closed its $40 billion round, it became one of the most valuable private companies in history. The secondary market is now quietly repricing that distinction -- not by disputing OpenAI's technical achievements, but by asking a harder question: which company's valuation reflects where the industry is going, and which one reflects where it has been?

Both OpenAI and Anthropic have signalled interest in public offerings this year, which means the secondary market divergence isn't just an abstract signal -- it's a preview of how public investors will receive each company. Capital allocated to tech IPOs is finite. In a market where institutional investors focused on late-stage private companies have grown significantly over the past decade, the competition for exit timing has become as consequential as the competition for market share.

The structural dynamics are straightforward. The first mover captures the deepest pool of available investment. Whoever follows faces diminished capital supply and heightened scrutiny. If Anthropic's secondary market premium carries into its public debut, it enters with momentum and pricing power. If OpenAI's discount persists, it faces the unenviable position of going public into a market that has already decided it overpaid.

The secondary market has been wrong before. But it has rarely been this decisive. Two billion dollars chasing one company while six hundred million dollars of another sits unsold isn't noise -- it's the sound of the AI race being repriced in real time, and the outcome will shape how the next generation of AI companies gets funded, valued, and ultimately judged.
