Anthropic Said to Top $1 Trillion Valuation in Private Market Trading
SAN FRANCISCO — Anthropic, the artificial intelligence safety company behind the Claude AI assistant, has seen its valuation surpass $1 trillion in pre-IPO private market trading, according to a report from Seeking Alpha.
The milestone places Anthropic among a rarified group of technology companies to reach the 13-figure threshold, underscoring the intense investor appetite for leading AI firms as the industry continues its rapid expansion.
The valuation, tracked through private secondary market transactions where existing shareholders sell stakes to new investors, signals strong confidence in the San Francisco-based company ahead of a widely anticipated initial public offering. Private market valuations can fluctuate and are not subject to the same pricing rigor as public exchanges or formal fundraising rounds.
Anthropic, founded in 2021 by former OpenAI executives Dario and Daniela Amodei, has positioned itself as a leading competitor in the foundation model race. The company’s Claude family of AI models competes directly with OpenAI’s GPT series, Google DeepMind’s Gemini and Meta’s Llama models.
The company has raised billions of dollars from investors including Google, which has committed up to $2 billion, and Amazon, which has invested up to $4 billion. Salesforce Ventures, Spark Capital and other institutional investors have also participated in prior funding rounds.
A $1 trillion valuation in private markets would represent a dramatic increase from Anthropic’s last reported formal fundraising round. The company was valued at $61.5 billion following a round in early 2025, meaning the private market figure suggests a more than tenfold increase in perceived value over roughly a year.
The surge reflects broader trends in AI company valuations, as investors compete for exposure to what many view as a transformational technology sector. OpenAI, Anthropic’s chief rival, has also seen its private valuation climb sharply in recent quarters.
For Anthropic’s employees and early investors, the private market activity provides a potential path to liquidity ahead of any formal public offering. Secondary transactions allow shareholders to sell portions of their holdings without waiting for an IPO.
Industry analysts have pointed to Anthropic’s emphasis on AI safety research, its enterprise partnerships and the growing adoption of Claude across business applications as factors driving investor interest.
Neither Anthropic nor its major investors have publicly confirmed the private market valuation figures or announced a timeline for an IPO.
