Anthropic, founded in 2021 by former OpenAI executives, has rapidly grown into a leading AI company with a focus on safety and alignment. Its valuation soared to $380 billion after its Series G funding in February 2026, driven by strong investor interest in large language models. The company’s revenue model involves multiple cloud channels, notably AWS, Google Cloud, and Microsoft Azure, raising complex accounting issues around revenue recognition. The broader AI market has seen a surge in valuations, with secondary-market activity suggesting a potential $1 trillion+ valuation for Anthropic, reflecting high investor confidence.

The company’s disclosures will be scrutinized for transparency on these issues, as they could impact pricing and investor appetite.
