xAI is looking more like a data center REIT than a frontier lab

By signing large-scale GPU capacity partnerships with Anthropic and Google, xAI is building a business model that resembles a data center operator (REIT) more than a simple AI lab.

Key Partnerships and Revenue Structure

• Anthropic: xAI is providing about 220,000 GPUs at a 300MW scale, generating up to $1.25 billion in monthly revenue. This is helping Anthropic address capacity shortages for its Claude service.
• Google: A contract worth about $920 million per month has been signed, based on 110,000 GPUs.
• Profitability: Excluding operating costs and depreciation, this is a highly profitable structure capable of recovering the entire capital expenditure within about 18 months. Power costs account for less than 1% of revenue, which is very low.

Infrastructure Execution and Strategic Risk xAI/SpaceX has demonstrated strong infrastructure execution capability by building the Colossus 1 data center in just 122 days. However, there are also strategic concerns that as computing resources that should be used for training and inference of Grok are instead leased to competitors, xAI could fall behind in the race to develop frontier models.
