For Amazon, the connection is both equity and business: it has invested in Anthropic and supplies cloud computing and Claude distribution through AWS. Google’s exposure is commercial, through cloud distribution and TPU capacity; the sources reviewed do not establish Alphabet’s current Anthropic equity stake. Neither company’s stock is guaranteed to benefit if Anthropic lists.
Anthropic has filed confidentially, but is not yet public
On June 1, 2026, Anthropic said it had confidentially submitted a proposed IPO filing to the SEC. The company said the filing gave it the option to go public after SEC review, and that an offering would depend on market conditions and other factors. It had not decided how many shares to offer or at what price, according to the Associated Press.
On September 29, 2026, Reuters reported that it had reviewed a copy of Anthropic’s confidential IPO prospectus. The filing itself was not publicly available in the sources reviewed. As of October 7, 2026, these reports describe a possible offering, not a completed listing or confirmed terms. A public listing could give investors more information once the company’s disclosures become public, but it would not by itself settle what Anthropic is worth or how its commercial partners’ shares should be valued.
How Amazon’s Anthropic exposure works
Equity, a financing facility, and a possible path to liquidity
Amazon’s Q2 2026 Form 10-Q says it invested $5 billion in Anthropic Series G and another $5 billion in Series H during the quarter. The filing also describes a financing facility of up to $20 billion. Initially, none was available to draw until compute-delivery milestones were met; after the Series H investment, $15 billion remained available under the facility.

#1 Best Overall
Amazon says draws after an IPO or another liquidity event may take the form of Anthropic common stock, subject to an ownership cap. It expects a customary post-IPO lock-up, followed by applicable securities-law restrictions. These terms describe a possible conversion and eventual sale route, not immediate cash proceeds or a guaranteed profit. The filing does not make a public listing certain.
Accounting marks are not cash from a sale
Amazon reported approximately $50.5 billion of upward adjustments to the fair value of its Anthropic nonvoting preferred stock in Q2 2026, and $62.8 billion for the first half of 2026. Amazon attributed the adjustments to observable price changes related to Anthropic financings. It classified the valuation measurements as Level 3 and said its methods included estimates about the timing and type of liquidity events and discounts for lack of marketability.
Those accounting marks can affect reported results before any IPO or sale, but they are not realized proceeds. Their size also does not mean Amazon could sell its holding for the marked value today.
AWS revenue opportunity comes with utilization risk
Anthropic’s April 20, 2026 announcement said it would commit more than $100 billion over ten years to AWS technologies under an expanded arrangement, securing up to 5 gigawatts of new capacity for Claude. Anthropic described AWS as its primary training and cloud provider for mission-critical workloads and said more than 100,000 customers ran Claude on Amazon Bedrock.
The arrangement can support AWS demand and use of Amazon’s custom chips, but the scale of the commitment makes Anthropic’s growth and ability to use capacity relevant to Amazon as well. A commitment is not proof that every planned unit of capacity will be delivered on schedule or fully utilized.
What Google’s relationship establishes—and what it does not
Cloud distribution and TPU capacity
Reuters reported that Amazon and Google together routed 47% of Anthropic’s 2025 customer sales through cloud marketplaces. That is a combined figure, not Google’s individual share. Reuters characterized both companies as investors, compute suppliers, distributors that collect customer bills, and competitors in AI.
Alphabet’s Q2 2026 Form 10-Q discusses a limited number of TPU supply agreements for customers with specialized, high-scale workloads. It warns that long-duration commercial agreements can create obligations and excess-capacity risks, including if counterparties or vendors do not perform. A September 2026 Broadcom SEC filing says Anthropic is expected, beginning in 2027, to access approximately 3.5 gigawatts through Broadcom as part of multiple gigawatts of next-generation TPU-based AI compute capacity committed under Anthropic’s expanded collaboration with Google and Broadcom. These disclosures support an infrastructure and demand connection; they do not establish that all capacity will be consumed.
Alphabet’s exact equity stake is not established here
The sources reviewed do not give a comparable, current amount or terms for Alphabet’s Anthropic equity holding. It would be misleading to infer Alphabet’s ownership from its role in TPU supply or cloud distribution, or to compare an assumed stake with Amazon’s disclosed terms. For investors, Google’s established exposure in these materials is principally commercial rather than a quantified equity position.
What the reported prospectus figures say about Anthropic’s business
The figures below come from Reuters’ September 29, 2026 account of Anthropic’s confidential prospectus, not from a publicly inspectable filing. They indicate rapid revenue growth alongside losses, dependence on cloud channels, and large long-term computing obligations.
| Reported item | Figure and qualification | Why it matters to investors in Amazon and Alphabet |
|---|---|---|
| 2025 revenue | Nearly $4.6 billion, according to Reuters’ report of the confidential prospectus. | Revenue growth can drive demand for the cloud and compute used to deliver Claude. |
| 2025 operating losses | More than $8 billion, according to Reuters’ report of the confidential prospectus. | Losses make funding needs and the ability to turn growth into sustainable economics important to the durability of partner demand. |
| Cloud marketplace sales | About $2.16 billion in 2025, equal to 47% of annual revenue, according to Reuters’ analysis of the confidential prospectus. | Marketplace channels can bring customers to cloud partners, while also concentrating distribution among a limited number of platforms. |
| Distribution fees | Approximately $351 million paid to cloud platforms, according to Reuters’ analysis of the confidential prospectus. | Cloud partners can earn fees for distribution in addition to revenue tied to compute. |
| Revenue mix | About $3.8 billion of 2025 revenue came from consumption-based Claude usage and $789 million from subscriptions, Reuters reported from the confidential prospectus. | Consumption-linked revenue makes customer usage a key driver of infrastructure demand; Reuters said Anthropic expected it to remain the substantial majority. |
| Hosting and computing commitments | $54.6 billion of non-cancellable commitments at 2025 year-end, according to Reuters’ report of the confidential prospectus. | These obligations may support capacity access but also create substantial fixed commitments. |
| Long-term commitments and capacity | More than $417 billion in total long-term commitments by early 2026, covering 3.5 gigawatts of dedicated computing capacity, according to Reuters’ report of the confidential prospectus. | Actual delivery, demand, utilization, and the ability to meet these obligations matter to Anthropic and its infrastructure partners. |
Anthropic’s prospectus, as reported by Reuters, described partner sales networks as a way to reach customers at scale. It also acknowledged that reliance on a limited number of partners and suppliers could create conflicts and affect access to compute. That tension is central: partnerships can accelerate distribution and infrastructure access, but they can also make a company dependent on firms that compete with it.

| Exposure | Amazon | Alphabet / Google |
|---|---|---|
| Disclosed equity terms | Amazon’s Q2 2026 Form 10-Q reports $5 billion invested in Series G and $5 billion in Series H during Q2 2026, plus a facility with $15 billion remaining after the Series H investment. Post-liquidity-event draws may take the form of common stock, subject to an ownership cap and expected lock-up. | The sources reviewed do not establish Alphabet’s current stake amount or comparable terms. |

| Compute relationship | Anthropic announced a commitment of more than $100 billion over ten years to AWS technologies and up to 5 gigawatts of new capacity for Claude. | Google and Broadcom collaboration includes multiple gigawatts of next-generation TPU-based AI compute capacity; Broadcom’s September 2026 SEC filing says Anthropic is expected to access approximately 3.5 gigawatts through Broadcom beginning in 2027. |
| Valuation sensitivity | Amazon reported Level 3 fair-value upward adjustments of approximately $50.5 billion in Q2 2026 and $62.8 billion in the first half of 2026 on Anthropic preferred stock; these were accounting marks, not sale proceeds. | No comparable Anthropic-equity valuation adjustment is established by the sources reviewed. |
| Capacity and contract risk | AWS capacity and the multiyear commitment can support demand, but utilization depends on Anthropic’s ability to grow and use the capacity. | Alphabet’s Q2 2026 Form 10-Q warns that long-duration TPU agreements can create obligations and excess capacity if customers, counterparties, or vendors do not perform. |
| Competitive conflict | Amazon is both a commercial partner and an AI competitor, according to Reuters’ characterization of the relationship. | Google is both a commercial partner and an AI competitor, according to Reuters’ characterization of the relationship. |
What could help or hurt the investment case
Potential benefits
- If Claude usage grows, Amazon and Google may see more cloud, marketplace, or compute demand.
- Amazon’s stake gives it equity-related exposure in addition to AWS business, and its filing describes conditions under which some financing draws after a liquidity event may be common stock.
- A public listing could make Anthropic’s financial position and valuation more observable after public disclosures are available.
Key risks
- Partner concentration: A large share of Anthropic’s reported 2025 revenue came through cloud marketplaces, while a limited number of partners also supply critical compute. Dependence can create bargaining power and conflict risks.
- Execution and capital needs: Reuters reported more than $8 billion in 2025 operating losses and very large long-term computing commitments from Anthropic’s confidential prospectus. Growth alone does not show whether those obligations will be economically sustainable.
- Capacity utilization: Infrastructure commitments can be valuable when demand materializes; delayed, underused, or difficult-to-redeploy capacity can weigh on providers and customers.
- IPO terms and timing: A confidential filing does not ensure a listing. Valuation, dilution, share conversion, lock-up terms, and the actual size of each holding will matter more than an IPO headline.
- Competition: Amazon and Google can benefit as suppliers while also competing with Anthropic in AI, creating incentives that may not always align.
What investors should watch next
- Whether Anthropic completes an offering and publishes prospectus terms, including valuation, share count, and risk disclosures.
- Any updated Amazon filing on facility availability, ownership caps, conversion terms, lock-up, and fair-value measurements.
- Evidence that announced compute capacity is being delivered and used, rather than only committed.
- Updates to Anthropic’s revenue mix, losses, marketplace dependence, and long-term obligations once public disclosures are available.
- Whether Amazon and Alphabet describe measurable cloud or TPU demand attributable to Anthropic, rather than assuming that every announced commitment translates into utilization or profit.
The relationship can support both companies’ AI infrastructure businesses, but it does not make either stock a direct proxy for Anthropic. Amazon’s disclosed equity and accounting exposure is more specific; Google’s established connection in the available materials is cloud distribution and TPU compute, with no comparable current stake figure. The eventual effect on AMZN or GOOGL depends on commercial economics and utilization as well as IPO terms, not simply on Anthropic going public.
