For years, OpenAI was the undisputed darling of the private technology markets — a company whose shares traded on secondary exchanges with the kind of fervor usually reserved for pre-IPO tech giants destined to reshape entire industries. That era may be ending. Not with a dramatic crash, but with the quiet, unmistakable shift of capital from one bet to another.
According to Bloomberg, demand for OpenAI shares on secondary markets has declined markedly in recent months, even as shares of rival Anthropic have surged in popularity among the same investor class. The dynamic represents something more than a simple rotation. It signals a fundamental reassessment of which company is best positioned to capture the enormous economic value that artificial intelligence promises — and which one may have already been priced for perfection.
The numbers tell a stark story. Secondary-market brokers report that bid interest for OpenAI shares has cooled significantly since the start of 2026, with some platforms seeing a drop of 30% or more in inquiry volume compared to the same period last year. Meanwhile, Anthropic shares — which were difficult to source even six months ago — have become the most sought-after private tech asset on several major secondary platforms. The spread between willing buyers and willing sellers for Anthropic has tightened considerably, a textbook sign of rising demand and increasing price discovery.
So what changed?
The answer is multifaceted, but it starts with execution. Anthropic’s Claude model family has made significant commercial inroads over the past year, particularly among enterprise customers who prize safety, reliability, and the kind of structured reasoning capabilities that have become table stakes for deploying AI in regulated industries. Financial services firms, healthcare organizations, and government contractors have gravitated toward Anthropic’s approach, which emphasizes interpretability and constitutional AI principles that make compliance officers sleep a little easier at night.
OpenAI, by contrast, has faced a string of challenges that have taken some of the luster off its once-untouchable brand. The company’s much-publicized restructuring from a nonprofit to a for-profit entity — a process that dragged on through much of 2025 and into early 2026 — created uncertainty among investors who weren’t sure what corporate governance would look like on the other side. Legal battles over the conversion consumed management attention. And while OpenAI’s products remain widely used, particularly ChatGPT and its API services, growth rates have decelerated from the torrid pace that once justified eye-watering valuations.
There’s also the matter of competition itself. When OpenAI first captured the public imagination with the launch of ChatGPT in late 2022, it had a substantial lead over every other player in generative AI. That lead has narrowed — dramatically. Google’s Gemini models have improved at a rapid clip. Meta’s open-source Llama models have eaten into OpenAI’s developer mindshare. And Anthropic’s Claude has, by many independent benchmarks, matched or exceeded GPT-4’s successors on key tasks involving complex reasoning, code generation, and nuanced instruction-following.
A crowded field.
The secondary-market dynamics reflect a broader investor psychology that anyone who lived through the dot-com era or the social media wars of the 2010s would recognize immediately. Capital flows toward perceived momentum, and right now, Anthropic has it. The company raised a massive round from Amazon in 2023 and has continued to attract blue-chip institutional backing. Its revenue growth trajectory, while still private, has reportedly exceeded internal projections for multiple consecutive quarters, according to people familiar with the matter cited by Bloomberg.
But the shift isn’t just about Anthropic doing well. It’s also about what’s happening inside OpenAI.
Sam Altman’s company has made aggressive bets on hardware, compute infrastructure, and a sprawling product portfolio that now includes everything from consumer chatbots to enterprise platforms to robotics partnerships. The ambition is staggering. Yet some investors have begun to question whether OpenAI is trying to do too much, too fast, spreading itself across too many fronts while its core model advantage erodes. The company’s burn rate remains enormous — estimated at several billion dollars annually — and while it generates substantial revenue, profitability remains distant.
Secondary-market pricing is always imprecise for private companies, but the signals are directional and hard to ignore. OpenAI shares that were trading at implied valuations north of $300 billion in late 2025 have seen asking prices soften. Some brokers report that sellers are now accepting discounts of 10-15% to move their positions, a sharp reversal from the premium-to-last-round pricing that characterized the market just months ago. Anthropic, meanwhile, is trading at or above its last private valuation, with some transactions reportedly pricing the company in the range of $80-100 billion — a remarkable figure for a company that didn’t exist before 2021.
The irony is thick. Anthropic was founded by former OpenAI executives — most notably Dario and Daniela Amodei — who left over disagreements about the direction and safety practices of their former employer. What began as a philosophical split has become a commercial rivalry, and the market is now placing its bets accordingly.
None of this means OpenAI is in trouble. Not really. The company still commands the largest consumer AI user base in the world. Its brand recognition dwarfs that of any competitor. And its partnership with Microsoft, which has invested more than $13 billion in the company, provides a distribution channel that Anthropic — despite its Amazon relationship — can’t yet match. ChatGPT remains a household name. Claude is not. At least not yet.
But secondary markets are forward-looking instruments, and what they’re pricing right now is a future in which the AI industry doesn’t have a single dominant winner. Instead, it’s shaping up to be a multi-player contest where differentiation matters more than first-mover advantage. Anthropic’s focus on safety and enterprise reliability has given it a distinct positioning that resonates with a specific, and very large, customer segment. OpenAI’s broader consumer play is powerful but faces margin pressure from free alternatives and open-source models.
The talent war adds another dimension. Anthropic has been on an aggressive hiring spree, poaching top researchers not just from OpenAI but from Google DeepMind and Meta’s FAIR lab. Compensation packages at Anthropic have reportedly risen to match or exceed OpenAI’s, fueled by the company’s rising valuation and the equity upside that comes with being perceived as the next great AI platform company. For top-tier machine learning researchers — the scarcest resource in technology today — the choice of employer is itself a bet on the future. And more of them are choosing Anthropic.
This matters because in AI, talent is the moat. Models degrade without constant improvement. Training runs require not just compute but the kind of institutional knowledge and research intuition that lives in the heads of a few hundred people worldwide. When those people move, competitive advantage moves with them.
There are also geopolitical considerations at play. Anthropic’s relationship with Amazon Web Services gives it a natural on-ramp to the federal government and defense sector, markets where AWS has invested heavily and built trust over more than a decade. OpenAI’s Microsoft partnership serves a similar function, but Anthropic has been more aggressive in pursuing government AI contracts, particularly in areas related to national security and intelligence analysis. These contracts, while not always large in revenue terms, carry enormous strategic significance — and signal to investors that Anthropic is building the kind of institutional relationships that create durable competitive positions.
And then there’s the question of structure.
OpenAI’s protracted conversion from a capped-profit entity to a more traditional corporate structure created months of uncertainty for secondary-market buyers. Who wants to acquire shares in a company when you’re not entirely sure what those shares will look like after a corporate reorganization? The ambiguity acted as a drag on secondary demand, and while the conversion is now largely complete, the residual caution lingers. Anthropic, as a straightforward C-corporation with a clear cap table and standard investor rights, presents none of those complications. For secondary buyers who prize clean legal structures — and they all do — that simplicity is a meaningful advantage.
Industry observers caution against reading too much into secondary-market trends, which can be volatile and driven by a relatively small number of transactions. A single large block sale by an early OpenAI employee, for instance, can temporarily depress pricing without reflecting any fundamental change in the company’s prospects. But the sustained nature of the shift — months of declining demand for OpenAI paired with months of rising demand for Anthropic — suggests something more structural is at work.
“Secondary markets are noisy, but they’re not random,” one broker who facilitates AI company share transactions told Bloomberg. “When you see a persistent change in flow like this, it reflects a genuine change in how sophisticated buyers are thinking about relative value.”
Relative value. That’s the key phrase. It’s not that investors have soured on AI — far from it. Capital allocation to the sector continues to accelerate across venture, growth equity, and public markets. What’s changed is the distribution of enthusiasm within the sector. The question is no longer whether AI will generate enormous economic returns, but which companies will capture those returns. And right now, the smart money is diversifying away from OpenAI’s concentration risk and toward Anthropic’s more focused, enterprise-oriented approach.
This doesn’t have to be permanent. OpenAI could announce a breakthrough model that reestablishes clear technical superiority. It could execute a public offering that gives the market a definitive price and eliminates the uncertainty that has plagued its secondary trading. It could resolve its governance questions in a way that reassures institutional investors. Any of these developments would likely reverse the current trend.
But for now, the momentum belongs to Anthropic. In Silicon Valley, momentum is currency — sometimes literally. The more investors chase Anthropic shares on secondary markets, the higher the implied valuation goes, which makes it easier for the company to raise primary capital on favorable terms, which funds more hiring and compute, which produces better models, which attracts more customers, which drives more revenue, which draws more investor interest. A virtuous cycle, if it holds.
OpenAI’s cycle, at least on secondary markets, has tilted in the other direction. Not into a death spiral — nothing so dramatic — but into a period of recalibration where the market is asking whether the world’s most famous AI company is still the world’s best AI investment.
The answer, increasingly, is: it depends on what you’re buying. If you want exposure to the broadest consumer AI brand with massive distribution through Microsoft, OpenAI remains the obvious choice. If you want exposure to what may be the fastest-growing enterprise AI platform with a safety-first reputation and deepening government relationships, Anthropic is pulling ahead.
Two companies. Two visions. Two very different secondary-market trajectories.
And a reminder, as sharp as any in recent tech history, that being first doesn’t mean being best — and that being best today doesn’t guarantee being best tomorrow. The AI race isn’t a sprint. It never was. It’s something longer, more grueling, and far less predictable than the breathless coverage of the past three years might suggest. The secondary market, in its quiet, transactional way, is finally pricing that reality in.
