Why is Google Doubling Down on Anthropic with a US$40bn Bet?

In recent years, the AI sector has been defined by high-stakes investment stories. Few developments, however, have been as striking as Google’s multi-billion-dollar bet on its rival Anthropic. 

The two companies have long competed for dominance with their respective Gemini and Claude models. 

Google is now bridging this rivalry with an investment worth US$10bn at a US$350bn valuation, with another US$30bn to potentially follow if Anthropic hits specific performance milestones.

The agreement significantly strengthens the operational relationship between the two firms, as Anthropic remains a primary customer of Google’s chips and cloud services. 

This deal will see Google Cloud provide 5GW of computing capacity to Anthropic over the next five years, with the potential for further scaling.

Earlier in April, Anthropic signed an agreement with Google and Broadcom to access multiple gigawatts of next-generation TPU capacity starting in 2027. This infrastructure expansion will power frontier Claude models to meet surging global customer demand. 

The infrastructure race

Google’s tensor processing units (TPUs) remain one of the premier alternatives to NVIDIA chips, making them a scarce and precious resource for Anthropic. 

Anthropic, which is considering an initial public offering as soon as October 2026, has been on the hunt for more infrastructure to meet surging demand. 

Its Claude Code tool has quickly become a standard for engineers across Silicon Valley, including some at Google. The Claude Cowork agent, which can be used for a wider range of tasks, is also growing in popularity.

Dario Amodei, Chief Executive Officer at Anthropic, maintains deep roots at Google, having worked there as an AI researcher earlier in his career. Since he founded the company in 2021, the two firms have maintained close ties.

In 2025, Google agreed to provide up to one million TPU chips to Anthropic in a deal worth tens of billions of dollars, following an initial US$3bn investment.

Yet, as Google pours more money into its partner, the companies are also battling for market dominance. 

Google's leaders have expressed increasing concern regarding the company’s position in the AI coding market as they find themselves competing directly with an Anthropic suite that currently leads the sector.

Reading between the lines

Many are raising eyebrows over the latest investment from Google, particularly as Alphabet is set to spend up to US$185bn in capital expenditures this year. 

This follows a US$32bn all-cash acquisition of cybersecurity firm Wiz, a move that consumes a significant portion of the remaining net cash on the balance sheet of the American multinational company.

While the scale of this spending may lead some to question the wisdom of further investment in Anthropic, the numbers suggest that Google is securing a bargain. 

To understand the valuation, one must look at the revenue trajectory of Anthropic, which has undergone a transformation rarely seen in technology history. 

Annualised revenue stood at US$1bn at the end of 2024 before climbing to US$9bn by the end of 2025 and reaching a staggering US$30bn in early April 2026.

Anthropic has tripled its revenue in just the last four months. Currently standing at a US$350bn valuation, Google is essentially buying in at roughly 12 times sales. 

On top of that, internal confidence at the AI firm is equally high, as evidenced by a share tender offered to long-tenured employees in April 2026. 

At the US$350bn mark, many staff members chose to hold their shares rather than cash out.  Anthropic team now seems to be betting on a much higher valuation during a rumoured IPO as early as October 2026. 

A technology revolution like this was unheard of before the Gen AI boom. However, Anthropic’s path forward is not without hurdles. It is currently fighting a Pentagon designation in court which labels it a supply-chain risk following a dispute over military use.

Financial analysts have also raised concerns regarding circular deals in which technology giants invest in start-ups like Anthropic while simultaneously selling them the chips and data centre capacity required for their operations.
