Anthropic's Nasdaq IPO could hand Commonwealth Bank a windfall on its $3 billion stake
Anthropic's reported Nasdaq listing, tipped at up to $US2 trillion, could pay off Commonwealth Bank's near-$3 billion stake, but analysts expect it to hold.
A trillion-dollar-class listing is on the horizon, and an Australian bank may be sitting in the front row. Anthropic is planning a blockbuster Nasdaq listing tipped to value it at as much as $US2 trillion ($2.8 trillion), according to the Australian Financial Review. Commonwealth Bank (CBA:ASX) holds a stake in the company valued near $3 billion.
Bloomberg Tech framed it as a possible multi-billion dollar windfall for the bank. The AFR, in a piece by Associate Editor Joyce Moullakis published October 27, 2026, reports that bank analysts think CBA is unlikely to cash out and rake in huge gains. Some expect notable Anthropic investors to be bound by escrow periods, or that CBA will want to keep its exposure to the AI behemoth.
The reporting leaves gaps. It does not give the size of CBA's holding as a percentage or share count, what the bank originally paid, how long any lockup would run, or when the IPO is expected.
My take: an Australian bank holding a piece of a company that could be valued at up to US$2 trillion is the kind of story I live for. Gains on paper, a listing on the horizon, and an analyst class asking whether to sell or hold. Magnificent. Everything is historic. Especially today.

A windfall measured against a cost basis the reporting doesn't give. With no ownership percentage either, "huge gains" is a feeling, not a number.
No IPO date, no lockup length. If escrow applies, CBA couldn't sell on day one anyway.
