## What AI research, patents and partnerships does Commonwealth Bank have?

Commonwealth Bank buys and partners more than it patents. Its 2026 annual report names AWS, Anthropic, Microsoft and OpenAI as strategic partners and carries an equity stake in Anthropic at A$1,527 million at June 30, 2026, against A$153 million a year earlier. OpenAI became a multi-year partner on August 13, 2025; the Anthropic partnership and investment were expanded in March 2025, and 20 CBA engineers joined Anthropic's Claude Frontier Academy in October 2026. Earlier bets include leading H2O.ai's $100 million Series E in November 2021 and running scam-baiting bots with Macquarie University spin-out Apate.ai. Research runs through a Human-Centred AI unit set up in November 2024, a five-year partnership with the University of Adelaide's Australian Institute for Machine Learning, Harvard's STAR Lab, an AI Attitudes Barometer with Melbourne Business School (February 2026) and a team of Distinguished AI Scientists led since June 15, 2026 by Chief AI Scientist Professor Mary-Anne Williams. Google Patents shows two published applications assigned to the bank, on vector embeddings and on translating non-natural language data, and no granted AI patent.

## Common questions

### How much is Commonwealth Bank's stake in Anthropic worth?

The 2026 annual report carries an unlisted equity investment in Anthropic PBC at A$1,527 million at June 30, 2026, up from A$153 million a year earlier. The value comes from Anthropic's May 2026 funding round, in which CBA did not participate. The bank announced an expanded partnership and investment in Anthropic on March 14, 2025, and in October 2026 sent 20 engineers to Anthropic's Claude Frontier Academy.

### Does Commonwealth Bank work with both OpenAI and Anthropic?

Yes. OpenAI became a multi-year strategic partner on August 13, 2025 and supplies ChatGPT Enterprise to nearly 50,000 staff; Anthropic is both a partner and an investee. The annual report lists AWS, Anthropic, Microsoft and OpenAI as strategic partners, and the San Francisco hub embeds CBA squads with all four. Financial terms of the lab agreements are not public.

### Does Commonwealth Bank hold AI patents?

Few are public. Google Patents lists two published applications assigned to Commonwealth Bank of Australia: US 2025/0307709 A1, a vector embedder for non-natural language data (October 2025), and AU 2025204862 A1 on translating such data into natural language (January 2026). No granted AI patent was found. The bank has instead shared one model, its Abuse in Transaction Descriptions detector, with other banks.

### Which universities does Commonwealth Bank partner with on AI?

Its December 2025 AI report names a five-year partnership with the University of Adelaide's Australian Institute for Machine Learning (2024) and an ongoing collaboration with Harvard's STAR Lab. In February 2026 it launched the AI Attitudes Barometer with Melbourne Business School, and in May 2026 it hired UNSW's Professor Mary-Anne Williams as its first Chief AI Scientist. It has also worked with MIT Sloan and the University of Technology Sydney on human-centred AI.

### What was Commonwealth Bank's investment in H2O.ai?

CBA led H2O.ai's $100 million Series E, announced on November 8, 2021, which valued the company at $1.7 billion; CBA was already a customer. CEO Matt Comyn said the investment and strategic partnership extended the bank's leadership in AI, and its then chief data and analytics officer Andrew McMullan joined H2O.ai's board. The bank has not disclosed the size of its stake.
