Anthropic, a prominent AI lab, has unveiled its extensive S-1 filing, shedding light on its financials ahead of a highly anticipated IPO. The document, released earlier this week, offers a comprehensive view of how the company generates revenue, but leaves several critical questions unanswered.
The filing reveals that CEO Dario Amodei and his six co-founders each hold over 200 million shares, potentially valuing their stakes in the billions if Anthropic achieves its projected valuation exceeding $1 trillion. Despite this, the prospectus has not clarified the management's expectations regarding the slowdown in revenue growth, which saw a sharp decline from 144% in the second quarter to 47% in the third quarter of 2026.
Anthropic reported $16.29 billion in revenue for the first half of 2026, a significant increase from $1.16 billion during the same period in 2025. However, the cost of revenue was $2.38 billion, resulting in an 85% gross margin. Violeta Todorova, a senior research analyst at Leverage Shares, expressed concerns about whether the company can sustain such growth rates, especially as computing demands rise.
The S-1 filing indicates that most of the cost of revenue is tied to compute and infrastructure expenses. Yet, it remains unclear how much of the future commitments are allocated for training new models versus serving existing customers. Nick Patience, AI lead at the Futurum Group, pointed out that this distinction is crucial for understanding future margins.
Anthropic's reliance on cloud service providers has led to a compute-constrained environment, where demand often exceeds supply. The company has previously sought more compute capacity than partners were willing to provide, raising questions about its ability to secure sufficient resources to meet customer needs.
Another point of interest is Anthropic's structure as a public benefit corporation. The co-founders, including Amodei, hold special voting power through a single Class F share, giving them 50.1% of the total voting power on shareholder matters. This governance structure, described as having "no direct public company precedent, " could impact investor sentiment and the eventual share price, as noted by Michael Field, chief equity strategist at Morningstar.
The company plans to issue different classes of shares, but the impact of this on investor control remains uncertain until trading begins. The IPO valuation, a key point of speculation, is yet to be disclosed. Analysts estimate it could range from $1 trillion to $2 trillion, a figure that could significantly influence the AI sector's market dynamics.
In the broader tech landscape, other major players are making moves. Apple has introduced its first touchscreen laptop, the MacBook Pro with ProLED XDR Display. SK Hynix reported record profits and announced over $25 billion in dividends and buybacks. Meanwhile, Nvidia and Advanced Micro Devices are investing $4 billion in Meta, which plans to raise $95 billion for AI infrastructure. Microsoft is offering employee buyouts to balance AI infrastructure costs with capital efficiency, and SpaceX has secured $40 billion in debt financing for GPUs to power AI systems.
As the IPO approaches, the market eagerly awaits further clarity on Anthropic's valuation and strategic direction.
