Anthropic’s potential initial public offering (IPO) could deliver extraordinary returns to its early investors. Venture capital firms such as Menlo Ventures, Sequoia Capital, Sound Ventures, and Spark Capital are reportedly positioned to make billions from their stakes in the artificial intelligence company.
However, the biggest winners of the Anthropic IPO may not be venture capital firms. Amazon and Google could stand to gain even more, thanks to their investments in Anthropic and their extensive cloud-computing agreements with the AI developer.
According to Anthropic’s registration statement filed with the U.S. Securities and Exchange Commission (SEC), no individual venture capital firm holds a stake large enough to meet the 5% threshold for inclusion in the principal stockholders’ table. That is unusual for a major technology IPO, where leading venture investors often own double-digit percentages of a company.
Anthropic’s enormous private valuation helps explain the difference. At a reported valuation of $965 billion, even a 1% ownership stake would be worth nearly $10 billion. For investors such as Menlo Ventures, a reported position worth approximately $14 billion represents only around 1.5% of the company.
But venture capital returns tell only part of the story. Anthropic’s relationships with Amazon and Google reveal how strategic investments in AI companies can generate value through equity ownership, convertible debt, and long-term cloud infrastructure contracts.
Why Anthropic’s IPO Could Create Unusual Investor Returns
In a conventional technology IPO, early venture capital investors often own substantial portions of the companies they helped finance. Anthropic’s reported valuation changes that equation.
At $965 billion, a relatively small ownership percentage can represent billions of dollars in potential value. This helps explain why prominent venture firms may have significant financial exposure to Anthropic without individually appearing among its principal stockholders.
The company’s capitalization also reflects the scale of investment required to develop and operate advanced AI models. Funding rounds have expanded Anthropic’s valuation, while strategic investors have supplied capital, computing infrastructure, and other resources needed to support its growth.
For venture capital firms, a public listing could create an opportunity to realize returns on their investments. For strategic investors, however, the potential benefits extend beyond share-price appreciation.
Amazon Could Be One of the Biggest Beneficiaries of Anthropic’s IPO
Amazon is particularly well positioned to benefit from Anthropic’s potential public listing. Its investment combines convertible notes, preferred stock, and a major commercial relationship through Amazon Web Services (AWS).
Amazon first backed Anthropic in 2023, committing to invest up to $4 billion. It subsequently expanded its financial support through additional investments and funding arrangements.
Rather than receiving all its ownership through conventional stock purchases, Amazon structured much of its early investment as convertible notes. These debt instruments can convert into equity when specified events occur, such as an IPO or sale, subject to the applicable contractual terms.
Amazon’s $97.9 billion convertible-note valuation
Anthropic’s SEC filing reports that Amazon held convertible notes with $6.2 billion in outstanding principal as of June 30, 2026. According to Amazon’s own regulatory filing, the notes were valued at approximately $97.9 billion at that date.
The difference between the principal amount and the reported fair value illustrates how dramatically Anthropic’s rising valuation has affected the potential economics of Amazon’s investment.
As the estimated value of the notes increased, Anthropic had to account for changes in the fair value of its financial obligations. Its income statement recorded $72.4 billion in adjustments during the first half of 2026 under the line item covering changes in the fair value of convertible notes, derivative liabilities, and simple agreements for future equity (SAFEs).
Importantly, this accounting charge was non-cash. It reflected changes in the estimated value of financial instruments rather than a cash payment of $72.4 billion by Anthropic.
How much of Anthropic could Amazon own?
According to Anthropic’s registration statement, Amazon’s convertible notes could convert into as many as 1.84 billion shares. However, a contractual cap limits Amazon to 12% of Anthropic’s partially diluted share count, which includes certain shares that have not yet been issued, such as stock options.
Amazon may waive the cap. Any notes that cannot convert because of the limit would remain outstanding and could convert in subsequent quarters, subject to the same restriction.
Amazon’s exposure also extends beyond its convertible notes.
In the second quarter of 2026, Amazon invested another $10 billion in nonvoting preferred stock, split between $5 billion investments in each of Anthropic’s two most recent funding rounds. Combined with approximately $8 billion invested through notes between 2023 and 2025, Amazon’s reported investment totals approximately $18 billion.
These arrangements give Amazon exposure to Anthropic’s potential equity appreciation while strengthening a business relationship that could remain valuable long after an IPO.
Amazon’s AWS Deal Adds Another Billion-Dollar Opportunity
Amazon’s potential returns are not limited to its financial investment. Anthropic has committed to spend at least $110 billion on AWS over the next 10 years.
That commitment is significant because developing and running advanced AI models requires enormous amounts of computing power. Training models, serving users, and expanding AI products can create substantial demand for cloud infrastructure.
For Amazon, the relationship therefore offers two potential sources of value:
- Investment returns: Its convertible notes and preferred stock could benefit from Anthropic’s valuation and eventual public-market performance.
- Cloud revenue: Anthropic’s infrastructure spending commitment could generate substantial business for AWS over the coming decade.
This combination makes the relationship strategically important. Amazon is not simply an investor hoping to profit from an AI company’s IPO; it is also a cloud provider positioned to supply computing resources to that company.
The arrangement illustrates how major technology companies can benefit financially from AI businesses even when those businesses develop products that compete with their own offerings.
Google Could Also Earn Billions From Anthropic
Google is another major beneficiary of Anthropic’s growth, with exposure through its equity investment and cloud-computing agreements.
Court filings reported by The New York Times indicated that Google held approximately 14% of Anthropic as of early 2025. Google has since invested more, including a reported $10 billion investment in April 2026.
However, subsequent funding rounds may have diluted Google’s ownership percentage. PitchBook analyst Harrison Rolfes estimated that Google’s current stake was closer to 5.6%, according to reporting by TechCrunch.
Even at that lower estimated percentage, Google’s position could be worth tens of billions of dollars at a reported $965 billion valuation, although the actual value would depend on the relevant share classes, dilution, transaction terms, and eventual public-market pricing.
Google’s cloud-computing agreement with Anthropic
Like Amazon, Google benefits from more than potential equity gains. Anthropic has secured at least $114 billion in cloud commitments through 2033, according to the reported figures.
These agreements are important because AI companies require significant computing infrastructure to train and deploy their models. Long-term cloud contracts can provide technology providers with substantial revenue opportunities while helping AI developers secure the capacity needed to grow.
For Google, the relationship creates a financial connection to Anthropic’s expansion even as Google develops its own competing AI models.
As with Amazon, however, the reported value of a commercial commitment should not be confused with guaranteed profit. Actual financial benefits depend on contract terms, spending patterns, operating costs, and the economics of delivering cloud services.
Why Amazon and Google May Benefit More Than Venture Capital Firms
Anthropic’s potential IPO highlights a broader shift in how investors can profit from the AI industry.
Traditional venture capital firms generally seek returns through ownership stakes in privately held companies. Their gains often depend on a liquidity event, such as an IPO, acquisition, or secondary share sale.
Amazon and Google have a different position. Both have invested capital in Anthropic and established commercial relationships that could generate revenue as the company grows.
Their potential benefits include:
- Equity appreciation: Shares and equity-linked instruments may become more valuable as Anthropic’s valuation rises.
- Convertible-note gains: Depending on the final terms and conversion mechanics, Amazon’s notes could translate into a significant equity position.
- Cloud infrastructure revenue: Long-term commitments create opportunities to sell computing capacity and related services.
- Strategic positioning: Close relationships with a leading AI developer can strengthen the technology providers’ roles in the broader AI ecosystem.
These advantages do not eliminate risk. The value of private investments can change, convertible instruments have complex terms, and commercial agreements do not guarantee specific profit margins.
Nevertheless, the combination of financial exposure and infrastructure revenue gives Amazon and Google multiple potential routes to benefit from Anthropic’s growth.
Anthropic’s Strategic Investors Also Present Competitive Risks
The same relationships that make Amazon and Google important financial partners could create conflicts of interest.
Both companies develop their own AI models and compete in markets that overlap with Anthropic’s business. Their interests may not always align with Anthropic’s priorities.
Cloud providers must balance serving Anthropic with investing in their own AI products, managing computing capacity, and competing for customers. Meanwhile, Anthropic’s reliance on external infrastructure providers can create dependencies that affect its costs, capacity, and strategic flexibility.
Anthropic’s SEC registration statement warns investors about risks associated with cloud providers that also develop competing AI technologies.
This is an important consideration for prospective public-market investors. A major strategic shareholder can offer capital, infrastructure, and commercial opportunities, but it can also introduce complex relationships that deserve close scrutiny.
What Anthropic’s Potential IPO Means for AI Investors
Anthropic’s potential IPO could become a landmark event for the artificial intelligence industry. A reported private valuation of $965 billion would make even relatively small ownership stakes extraordinarily valuable.
Venture capital firms could realize substantial returns, but Amazon and Google may have a particularly powerful combination of financial and commercial exposure.
Amazon’s convertible notes, preferred-stock investments, and AWS agreement give it several potential ways to benefit. Google’s equity position and cloud-computing commitments create a similar, though structurally different, opportunity.
The key takeaway is that the biggest financial winners of Anthropic’s IPO may be the technology companies that both invest in AI developers and provide the infrastructure they depend on.
For investors evaluating Anthropic ahead of a possible public listing, ownership percentages are only one part of the picture. Convertible securities, dilution, commercial contracts, competitive relationships, and the company’s final IPO terms will all help determine who ultimately captures the greatest share of its value.
