The value of Commonwealth Bank of Australia’s CBA stake in Anthropic rises from about A$153 million to about A$1.53 billion
According to Bloomberg, Commonwealth Bank of Australia (CBA) may profit from Anthropic’s initial public offering (IPO). The bank participated in Anthropic’s Series E financing in March 2025, and its stake was valued at A$153 million (about US$107.5 million) as of June 30, 2025.
As of the end of June 2026, with Anthropic’s valuation rising to US$965 billion, the value of CBA’s stake had increased to A$1.53 billion, about 10 times higher than before. However, this increase in value is an unrealized gain on paper, and whether it can ultimately be monetized through an IPO still depends on the listing process and related deal terms, including any lockup period or the company’s decision to retain exposure.

ABAB AI Insight
CBA, as a traditional bank, entered Anthropic through a strategic investment and has achieved a significant paper gain, reflecting the impact of rapid valuation expansion at AI companies on early institutional investors. The 10-fold increase is based on subsequent financing valuations rather than additional investment by CBA, and it is an unrealized gain. Anthropic’s planned IPO (with market discussion that the valuation could be even higher) provides a potential monetization window, but whether the bank actually sells, is subject to lockup restrictions, or chooses to hold for the long term will affect the final realized return.
Compared with early-stage venture capital, the bank’s exposure is relatively limited and more reflects a cautious trial by financial institutions into AI infrastructure. Actual returns still depend on IPO pricing, liquidity arrangements, and the bank’s capital management decisions.

An increase in paper valuation does not equal realized gains, especially when it depends on a subsequent liquidity event.
Institutional valuation updates for participation in early rounds usually reference the latest financing round rather than an independent audit.
