From Mocking to Partnership: Elon Musk Now Collaborates with Anthropic

Boss of the electric car company Tesla and rocket maker SpaceX, Elon Musk, has officially signed a partnership with the American artificial intelligence (AI) company, Anthropic.

In the agreement announced on Wednesday (6/5/2026) US time, Anthropic will use the computing capacity from SpaceX’s Colossus 1 data centre.

Colossus is a massive AI data centre previously built by Musk’s AI company, xAI.

That AI infrastructure is now under SpaceX’s umbrella after Musk announced the change of xAI to “SpaceXAI”.

He even once called Anthropic an “evil” company and mocked it with the name “Misanthropic”. Musk also accused the company of hating “Western civilisation” and stealing data to train AI models.

Now, Musk’s attitude has changed. In a post on platform X, he admitted being impressed by Anthropic’s approach to developing AI.

“I spent a lot of time last week with senior members of the Anthropic team to understand what they are doing to make Claude good for humanity. Everything looks fine to me,” Musk wrote.

Through this partnership, Anthropic says it will gain full access to the Colossus 1 computing capacity.

The data centre has power exceeding 300 megawatts. That infrastructure is also powered by more than 220,000 Nvidia graphics processors (GPUs).

Anthropic says this additional capacity will improve Claude services for paying customers.

The company has also immediately raised the usage limits for Claude Code and Claude Opus API starting today. Some of the announced changes include:

Anthropic also expressed interest in developing orbital AI computing together with SpaceX in the future.

At the same time, this partnership will also benefit SpaceX, as it can strengthen the company’s financial position ahead of its initial public offering (IPO) plans, as summarised by KompasTekno from Gizmodo.
