Anthropic is an AI startup staffed by a number of former OpenAI employees, who broke with the originalc ompany over the increasing commercial focus of OpenAI.

Elon Musk originally funded OpenAI and has criticized them over their direction.

A TechCrunch article on OpenAI includes this quote:

"The Information reported in early March that Anthropic was seeking to raise $300 million at $4.1 billion valuation, bringing its total raised to $1.3 billion. The deck confirms that target number, though only half was raised at the time of the document’s creation from a “confidential investor.”"

Is this confidential investor Elon Musk? (or a fund that Elon Musk directly heads up)

This market resolves YES if credible evidence that convinces me emerges that Elon Musk has invested at least $100 million in Anthropic.
