SpaceXAI, the merged entity born from Elon Musk’s xAI and SpaceX, is leasing its Colossus 1 supercomputer cluster to rival AI company Anthropic for roughly $5 billion per year. The four-year deal, announced on May 6, hands Anthropic access to more than 220,000 Nvidia GPUs and 300 megawatts of power, giving it one of the largest compute footprints in the industry almost overnight.

The timing is not subtle. xAI is preparing for an IPO slated for June 2026, with a target valuation of $1.75 trillion. Leasing out a massive but underused asset to a deep-pocketed competitor is one way to make the revenue line look significantly healthier before going public.

Why lease your supercomputer to a competitor

Colossus 1 was reportedly running at just 11% utilization. Industry benchmarks for GPU cluster utilization sit in the 35% to 45% range, meaning xAI’s flagship supercomputer was operating at roughly a quarter of what would be considered normal.

The lease is expected to generate between $5 billion and $6 billion annually for xAI. That cash flow directly offsets what have been reported as significant financial losses for the company.

Anthropic, the company behind the Claude family of AI models, gets a massive compute injection without having to build its own facility from scratch. Leasing lets Anthropic skip the construction phase and go straight to training bigger models.

What this says about Grok AI’s traction

The low utilization rate on Colossus 1 has sparked a separate conversation about Grok, xAI’s own AI assistant. If xAI’s in-house AI product were consuming serious compute, you wouldn’t expect its primary supercomputer to be sitting 89% idle.

Commentary on social media platform X has been split. Some analysts view the Anthropic lease as a savvy financial move, turning a depreciating asset into a revenue engine. Others read it as a quiet admission that Grok hasn’t gained the traction needed to justify the infrastructure xAI built for it.

For Anthropic, access to 220,000 GPUs and 300MW of power positions Claude to compete more aggressively with OpenAI’s GPT models and Google’s Gemini.

The crypto angle: meme tokens and market sentiment

Meme tokens linked to the xAI ecosystem, particularly those trading under the GROK ticker, have seen increased activity since the announcement. Meme token markets are essentially sentiment derivatives, and any major headline involving Elon Musk tends to move them.

The IPO itself is perhaps the biggest variable. A $1.75 trillion target valuation would place xAI among the most valuable companies on Earth. Investors watching AI-linked crypto assets should pay close attention to xAI’s IPO filings when they become public. The utilization numbers, revenue breakdown, and Grok adoption metrics will tell you more than any headline.
