Alphabet-Backed Anthropic Considers Share Sales Before IPO

AI startup Anthropic is considering an unusual IPO structure that would allow existing shareholders to sell their stakes as part of the public offering, according to a report by The Information from August 27, 2026. Anthropic's investors include Alphabet Inc., Google's parent company.

Departure from SpaceX Model

According to the report, Anthropic plans to deviate from the so-called SpaceX approach. SpaceX, Elon Musk's aerospace company, excludes existing shareholders from selling during financing rounds and potential IPOs, allowing only the placement of new shares. The alternative that Anthropic is considering would instead give existing shareholders – including employees, early investors, and strategic partners like Alphabet – the opportunity to create liquidity.

Such an approach could be attractive to venture capital investors and tech companies that have invested large sums in startups like Anthropic during the current AI investment wave. Alphabet has made multiple investments in Anthropic in recent years and is considered one of the most important backers of the OpenAI competitor.

Significance for Alphabet Shareholders

For Alphabet shareholders, a successful Anthropic IPO with the option for share sales would be a mechanism to realize the valuation gains of the investment. The exact amount of Alphabet's stake in Anthropic is not publicly known, but industry reports from recent years suggest investments in the hundreds of millions of dollars.

However, an Anthropic IPO is not imminent. The company has not yet announced concrete plans for a public offering. The considerations regarding a share sales option indicate that Anthropic is exploring its strategic options for future capital raising.

AI Boom Supports U.S. Economy

The report on Anthropic comes at a time when AI infrastructure investments are playing a central role in the U.S. economy. According to an analysis by Seeking Alpha from August 27, 2026, AI-related spending is currently nearly the only factor supporting U.S. economic growth. Market valuations are reaching levels comparable to the late 1990s, but there is a lack of broad economic support beyond AI infrastructure spending.

Alphabet benefits from this trend in multiple ways: as the parent company of Google, which develops its own AI products, as a cloud provider through Google Cloud Platform, and as an investor in external AI startups like Anthropic. Diversification across internal development and external investments allows the company to cover various AI development scenarios.
