Anthropic nears $1T valuation, releases Opus 4.8

Anthropic raised $65 billion in a Series H round and now has a valuation of $965 billion. For good measure, Anthropic said it now has an annual revenue run rate of $47 billion and released its Opus 4.8 model.

To say Anthropic's growth in 2026 has been exponential might be an understatement. Anthropic said its revenue run rate passed $47 billion earlier this month. In February, Anthropic was valued at $380 billion with an annual revenue run rate of $14 billion.

CFO Krishna Rao said the funding will "help us serve the historic demand we are experiencing, stay at the research frontier, and bring Claude to more of the places where work happens."

To keep that Claude engine humming, Anthropic said it has launched Claude Opus 4.8, which improves on its predecessor for the same price. Opus 4.8 offers users controls over the amount of effort Claude puts on a task, adds dynamic workflows to Claude Code and has a fast mode that operates at 2.5x the speed.
