Hey there, bargain hunter. Something happened this month that doesn’t come around often. On June 1, 2026, Anthropic filed a confidential S-1 with the SEC. Then, one week later on June 8, OpenAI did the same thing. Two of the most consequential private AI companies in history, filing for public markets in the same seven-day window.
The market is already processing it. The question is whether you’re positioned ahead of the noise or chasing it.
The Numbers First
Anthropic closed a $65 billion Series H in late May, pushing its post-money valuation to approximately $965 billion — briefly eclipsing OpenAI’s $852 billion valuation for the first time. Revenue tells the growth story better than any headline: the company’s annualized run-rate crossed $47 billion in May 2026, up from roughly $10 billion the prior year. Q2 2026 revenue is expected to hit $10.9 billion, with the company projecting its first profitable quarter — estimated at roughly $559 million in operating income. That’s not a science project anymore. That’s a business.
OpenAI, for its part, carries a $852 billion valuation and ChatGPT now reports 900 million weekly active users. Both companies are targeting public listings as early as fall 2026, with analysts widely expecting debut valuations at or above $1 trillion.
Slight tangent, but it matters — Anthropic is incorporated as a Public Benefit Corporation with a Long-Term Benefit Trust designed to protect its safety mission even under shareholder pressure. That structure is unusual and creates governance uncertainty that institutional investors will be pricing carefully. It’s neither purely good nor purely bad. It’s just different, and different things get mispriced.
The Part Most People Are Skipping
Retail investors can’t buy Anthropic pre-IPO through normal channels. That’s the constraint. But here’s where it gets interesting — you don’t need to.
Amazon and Alphabet are the two largest direct beneficiaries. Amazon’s original $8 billion investment was valued at over $74 billion at the end of Q1 2026 alone, and in Q1 the company booked $16.8 billion in pre-tax gains from its Anthropic position. Alphabet holds roughly 14% of Anthropic in straight equity — at the current $965 billion valuation, that stake is worth approximately $135 billion. Microsoft and Nvidia also hold positions, with Nvidia investing $10 billion and Microsoft $5 billion.
The less obvious names are worth watching too. Salesforce holds roughly a $5 billion stake — meaningful against its $165 billion market cap. Zoom’s Anthropic position recently grew to approximately $3 billion, representing around 13% of its entire enterprise value. For a stock trading at a discount to its software peers, that’s not a footnote.
And then there’s the infrastructure layer. Anthropic has committed to spending more than $100 billion with Amazon Web Services over the next decade, plus separate 5-gigawatt agreements with Google. That compute demand flows downstream to companies like Marvell Technology (MRVL), Credo Technology (CRDO), Celestica (CLS), Coherent (COHR), and Astera Labs (ALAB) — businesses that supply the physical hardware AI clusters actually run on. At Computex on June 2, Nvidia CEO Jensen Huang publicly called Marvell a potential trillion-dollar company. That’s not a casual comment.
What Could Go Wrong
The valuation math is aggressive. At approximately 21x run-rate revenue, Anthropic would be priced between a hypergrowth SaaS multiple and a mega-cap platform — and that assumes the growth rate holds. The company is also currently locked in a legal dispute after the Pentagon placed it on a supply-chain risk list, restricting federal contractors from using its services. Seven competitors, including OpenAI, were authorized for Pentagon use. That’s a real commercial risk heading into an IPO roadshow.
There’s also the supply glut question. OpenAI, Google, Meta, and others are all competing on pricing. If cheaper models erode Claude’s enterprise pricing power, the revenue growth story gets complicated fast.
The Action Framework
- AMZN: Deepest Anthropic exposure — equity stake plus $100B+ in commercial commitments flowing through AWS
- GOOGL: ~14% direct equity stake worth ~$135B at current valuation; also competes via Gemini
- MRVL: Custom silicon architect for hyperscalers, 18 confirmed XPU sockets in pipeline, Jensen Huang endorsement fresh off Computex
- CRM / ZM: Smaller market caps mean Anthropic stake is a larger percentage of total enterprise value — asymmetric if IPO rerates the position
- CRDO / CLS / ALAB / COHR: Infrastructure layer plays; benefit from compute buildout regardless of which AI model wins
The window before a high-profile IPO is usually when the most overlooked positioning happens. Not in the name that’s filing — in the names already trading that nobody is looking at through this lens yet.
Whether Anthropic lists in October or slips into early 2027, the infrastructure spending it’s already committed to doesn’t wait for a ticker symbol.
