Google agreed to invest up to $2 billion more in Anthropic — $500 million upfront with a further $1.5 billion over time — structured as a convertible note that would turn into equity at the company's next funding round. The Wall Street Journal reported the deal first and an Anthropic spokesperson confirmed the terms. It came a month after Amazon committed up to $4 billion in a similarly structured deal, cementing a pattern in which Anthropic drew capital and compute from multiple cloud giants rather than tying itself to one. Google had also been reported to invest about $300 million in February 2023.
