Anthropic IPO Could Bring Over A$1.5 Billion in Holding Gains to Commonwealth Bank of Australia

According to Bloomberg, the valuation of Anthropic shares held by Commonwealth Bank of Australia (CBA), Australia's largest lender, has increased approximately tenfold over a year. CBA participated in Anthropic's Series E financing round in March 2025, with the value of its stake rising from AU$153 million at the end of June 2025 to AU$1.53 billion at the end of June 2026. This valuation is calculated based on the post-financing valuation following a funding round completed by Anthropic in May 2026, a round in which CBA did not participate.
