Alphabet Shares Rise After Report of Massive Anthropic Cloud Commitment

Report says Anthropic will spend roughly $200 billion with Google Cloud over five years, lifting Alphabet stock in after-hours trade

By Leila Farooq GOOGL MSFT AMZN

Alphabet Inc. shares climbed about 2% in after-hours trading after reports that Anthropic has agreed to spend roughly $200 billion with Google Cloud across the next five years. The commitment, set to begin in 2027, reportedly represents more than 40% of Google’s disclosed cloud revenue backlog and follows an earlier Google pledge of 5 gigawatts of server capacity to Anthropic. The development underscores an increasing concentration of future cloud revenue among a small number of large AI firms.

Key Points

  • Anthropic reportedly agreed to spend about $200 billion with Google Cloud over five years starting in 2027.
  • That commitment would represent more than 40% of Google’s cloud revenue backlog as disclosed to investors.
  • Projected server rental spending by AI firms is accelerating, with Anthropic and OpenAI expected to be major drivers of cloud revenue.

Market reaction

Alphabet Inc. (NASDAQ:GOOGL) stock rose about 2% in after-hours trading Tuesday after reports indicated that Anthropic has agreed to allocate approximately $200 billion to Google Cloud over the coming five years. The buying interest followed the disclosure that the arrangement is slated to begin in 2027 and would make up more than 40% of Google’s stated cloud revenue backlog, according to the report.

Deal mechanics and capacity commitment

The reported agreement comes after Google pledged to supply Anthropic with 5 gigawatts of server capacity. That earlier commitment is now paired with the multi-year spending projection, which together highlight the scale of infrastructure required by large AI model operators and the long-term contracts cloud providers are striking with them.

Spending trends among AI firms

The report also outlined recent and projected server rental expenditures by leading AI companies. Anthropic was projected to spend more than $20 billion on server rentals this year, a pace roughly three times its spending in the prior year, according to the report’s mid-December projection. The same projection was published before Anthropic reported a revenue surge in the first quarter, which the report says could push actual spending above the mid-December estimate.

OpenAI is cited as another large cloud customer, with projected server spending of about $45 billion this year, up from roughly $17 billion the prior year. The majority of OpenAI’s server spending is expected to go to Microsoft, which has made investments exceeding $13 billion in the ChatGPT developer.

Implications for cloud providers

Analysts and investors frequently look to backlog figures as an indicator of future revenue prospects rather than current earnings. The report noted that the cloud industry’s principal providers are becoming increasingly dependent on a small number of AI firms - specifically Anthropic and OpenAI - for a significant share of their future revenue streams.

Context and limitations

Backlog totals reflect anticipated future revenue and do not translate directly into present earnings. The figures cited in the report are projections and company disclosures rather than realized revenue. The report’s mid-December projections for Anthropic predate the company’s reported first-quarter revenue gains, meaning the final spending amounts could differ from earlier estimates.


Key points

  • Anthropic has reportedly committed about $200 billion to Google Cloud over five years, starting in 2027.
  • The deal would account for more than 40% of Google’s disclosed cloud revenue backlog.
  • Projected server spending by major AI firms is rising sharply, with Anthropic and OpenAI expected to be significant customers for cloud providers.

Risks and uncertainties

  • Backlog figures represent expected future revenue and are not current earnings, leaving uncertainty about timing and realization of that revenue.
  • Mid-December projections for Anthropic’s server spending were made before a reported first-quarter revenue surge, so actual spending may diverge from earlier estimates.
  • The cloud industry appears to be increasingly concentrated in revenue exposure to a small number of AI firms, creating dependency risk for providers and investors.

Risks

  • Backlog figures indicate future revenue rather than current earnings, introducing uncertainty over when and whether the revenue will materialize.
  • Anthropic’s mid-December spending projection predated its first-quarter revenue surge, meaning final spending could differ from the projection.
  • Cloud providers are becoming increasingly dependent on a small number of AI customers, raising concentration risk for future revenue streams.
