Zoom’s Anthropic Stake Hits $1.3B: A 25x CVC Win

Two years ago, Zoom Communications wrote a $51 million check into Anthropic as part of the AI startup’s then-Series C. In its first-quarter fiscal-year-2027 results released this week, the video-conferencing company disclosed that the same stake is now carried at approximately $1.3 billion — a roughly 25x markup in 24 months on a single corporate venture-capital bet.

The disclosure, first surfaced via Bloomberg from Zoom’s regulatory filing, lands at a charged moment for the capital-markets plumbing behind AI: Anthropic is in the market with what is reportedly a $30 billion Series F at a $900 billion valuation, and several of the round’s co-leads are themselves writing $2 billion individual checks. For Zoom and the dozen-or-so other strategic investors who got in early, mark-to-market math is suddenly doing a lot of the work that the operating business used to do.

The numbers, and how they got here

Zoom’s Anthropic investment was struck in May 2023 as part of an integration partnership for the Claude family of large language models into Zoom’s AI features. The original cost basis was approximately $51 million, a small line item against Zoom’s then-$6 billion cash balance. Two years and four Anthropic funding rounds later, the implied fair value of that stake is roughly $1.3 billion — about 25.5x money on paper, before any tax or liquidity discount.

The mark moves with Anthropic’s primary-round valuation. Each time Anthropic prices a new round, every existing holder’s stake is implicitly re-marked. The trajectory of those rounds has been steep enough to redraw private-market valuation tables for AI:

According to Bloomberg’s read of the filing, the new Series F is being co-led by Sequoia Capital, Dragoneer Investment Group, Altimeter Capital and Greenoaks Capital Partners, each committing roughly $2 billion, with Founders Fund and General Catalyst also participating. Anthropic CEO Dario Amodei has publicly said the company saw “80-fold growth” in API usage and annualized revenue in the most recent quarter — the kind of operating-line print that underpins the valuation step-up.

Why this is a capital-markets story, not just a Zoom story

Corporate venture capital — CVC — has historically been the unglamorous half-sibling of financial VC. Strategic checks were small, often poorly tracked, and rarely thesis-driven. AI has flipped that. The biggest single AI investors in 2025–2026 by check size have not been crossover funds or sovereign wealth — they have been other tech companies writing strategic equity off their own balance sheets.

What sets Zoom’s situation apart from Microsoft’s OpenAI or Google’s Anthropic positions is the ratio: Microsoft committed roughly $14 billion to ride OpenAI’s rise; Zoom committed about 0.4% of that and is sitting on a markup that is now larger than Zoom’s most recent full quarter of revenue ($1.24 billion). For a company whose stock has spent two years range-bound on slower seat growth, that is not a rounding error.

What hits Zoom’s income statement

Under U.S. GAAP, equity investments without readily determinable fair values can be measured under the “measurement alternative” — cost minus impairment, plus or minus observable price changes from orderly transactions in the same or similar instruments. Anthropic’s near-quarterly priced rounds qualify as observable price changes. Each time a new round closes, holders like Zoom write up their carrying value, and the gain flows through net income.

That accounting treatment means Zoom’s quarterly EPS now has a meaningful, non-operating tailwind whenever Anthropic prices. Zoom reported adjusted EPS of $1.55 on revenue of $1.24 billion (up 5.5% year-over-year) and raised full-year guidance to a range of $5.96–$6.00 in EPS on $5.08–$5.09 billion in revenue. The stock pop that followed was reinforced by sell-side price-target hikes: Morgan Stanley to $105, Rosenblatt to $130, Benchmark to $125.

What investors should keep in mind

• Marks are not cash. Until Zoom either sells secondaries, accepts a tender, or Anthropic actually IPOs, the $1.3 billion is a balance-sheet entry, not realizable proceeds.
• Marks can come back down. The measurement alternative is symmetric — an Anthropic down-round would force a write-down. AI valuations have not yet been stress-tested by a true risk-off macro event.
• Concentration. A single private-stake mark is now bigger than several recent Zoom quarterly profits combined, which makes period-over-period earnings comparisons noisier.
• Liquidity discount. Anthropic primary-round valuations are paid by strategic investors with long-dated horizons. Tender or secondary transactions typically clear 10–25% below the primary mark — meaningful when measuring true economic value.

The broader capital-markets read

Three things are worth taking away. First, corporate balance sheets have become a top-tier source of AI capital formation, alongside venture funds and sovereign wealth. The arithmetic of Anthropic’s reported $30 billion Series F — including four ~$2 billion co-leads — would be impossible if only traditional VC pools were available. Second, the operating-line case for AI is finally aligning with the valuation case: an 80x year-over-year usage and revenue print, if accurate, is the kind of growth that historically justified later-stage step-ups in the public software market. Third, expect more disclosures like Zoom’s. Salesforce, Cisco, ServiceNow, Snowflake, Datadog and others have all reportedly written strategic checks into the AI stack; as Anthropic prints, OpenAI prints, and xAI prints, holders’ carrying values will move in lock-step — and Wall Street is increasingly modeling those stakes alongside the operating business.

The next data point comes when Anthropic’s Series F closes. Until then, Zoom’s filing is the cleanest single illustration of how a $51 million strategic check became one of the most valuable line items on a mid-cap software company’s balance sheet.
