Anthropic's revenue surge is reshaping investor expectations for the entire AI infrastructure sector.
According to Wind Trading Desk, a Bank of America Securities research report on April 8 indicated that the accelerated expansion of Anthropic's enterprise customer demand not only directly benefits its main cloud partners Amazon AWS and Google Cloud but also provides strong real-world backing for the core investment thesis of 'continuously high AI capital expenditures.'
Anthropic disclosed this week that its annualized recurring revenue (ARR) has surpassed $30 billion, a staggering increase from $9 billion at the end of 2025 and $19 billion just a month ago.
The primary driver is enterprise clients. The number of companies with annualized spending exceeding $1 million has doubled from 500 in mid-February to over 1,000. Concurrently, Anthropic announced new agreements with Google and Broadcom to secure 3.5 gigawatts of TPU computing power starting in 2027 to cope with &#34;massive customer demand.&#34;

<h2>Anthropic's Revenue Soars, Driven by Enterprise Demand</h2>
Anthropic's revenue growth curve is nearly vertical. According to the company, its ARR jumped from $9 billion to $30 billion within the first quarter, an increase of approximately $21 billion in a single quarter.
Based on Bank of America's estimates, the corresponding quarterly actual revenue growth may have exceeded $3 billion.
The core driver of growth comes from the enterprise side. The number of enterprise customers with annualized spending exceeding $1 million has doubled from over 500 to more than 1,000 in less than two months, demonstrating a significant acceleration in the penetration of the Claude model in commercial deployments.
Anthropic characterizes this trend as &#34;massive demand&#34; from customers, stating that the new computing power will be used to support the operation of its cutting-edge Claude models.
<h2>AWS Revenue Outlook: Anthropic's Contribution May Exceed Market Expectations</h2>
Amazon AWS is Anthropic's primary cloud service provider and training partner, a relationship that positions it as a direct beneficiary of Anthropic's demand explosion.
Considering Anthropic's substantial workload running on AWS and the sequential quarterly growth in training expenditures, Anthropic-related business alone could contribute over $1.3 billion in sequential revenue growth to AWS in the first quarter of this year.
This figure significantly exceeds Wall Street's previous expectation of approximately $1 billion in overall AWS sequential quarterly growth. AWS's sequential growth in the first quarter might reach $2 billion.
Looking ahead to the second quarter, Anthropic alone could contribute over $1 billion in additional sequential AWS revenue growth. It should be noted, however: if the incremental revenue from Anthropic has a lower profit margin, the boost to AWS's profitability forecast might be relatively limited.
<h2>Google TPU Mega-Deal: Potential Backlog of Over $100 Billion</h2>
Anthropic's new agreements with Google and Broadcom also inject a strong dose of confidence into Google Cloud's long-term revenue prospects.
Anthropic has signed new agreements with Google and Broadcom covering 3.5 gigawatts of TPU computing power, effective from 2027 to 2031. According to widespread media reports, this 3.5 gigawatt capacity is an incremental addition to the 1 gigawatt capacity already scheduled for launch in 2026, which was announced in October last year.
Google Cloud's revenue backlog for the fourth quarter of 2025 has increased by $85 billion quarter-over-quarter, with a significant portion likely coming from Anthropic.
Based on the commitment for the new 3.5 gigawatt capacity, this could imply an additional contract backlog of over $100 billion for Google—although this transaction was announced after the end of the first quarter and has not yet been reflected in the latest fiscal data.
It is worth noting that the aforementioned expenditure commitment is contingent upon Anthropic's &#34;continued commercial success,&#34; meaning that the business momentum of Anthropic and even OpenAI will be a crucial variable influencing market expectations for Google and Amazon stocks.
<h2>Implications for Investors: Cloud Revenue Upgrades and Capital Expenditure Expectations are Key</h2>
Anthropic's (and OpenAI's) latest disclosures resonate with the AI demand picture painted by hyperscale cloud providers, reinforcing the credibility of the &#34;AI capital expenditure investment theme.&#34;
For the upcoming earnings season, the possibility of exceeding expectations in cloud revenue is rising. The marginal variables that will have the greatest impact on market sentiment in the first quarter will be the performance of cloud business profit margins and any adjustments to companies' capital expenditure plans for 2026.
If cloud revenue exceeds expectations and capital expenditure plans remain unchanged, &#34;it will likely be welcomed by the market.&#34;
Based on the above logic, Bank of America maintains its &#34;Buy&#34; ratings on Amazon and Alphabet. For Amazon, the target price is $275 (based on sum-of-the-parts valuation, with AWS calculated at 8 times projected 2027 revenue); for Alphabet, the target price is $370 (based on 27 times projected 2027 GAAP earnings per share plus cash per share). Analysts believe both companies are well-positioned to capture the growth opportunities in enterprise AI demand.
