Anthropic's IPO puts power in the hands of founders, giving everyday shareholders little voice

Prospective Anthropic investors better buckle up, because the AI company's seven co-founders are firmly in the driver's seat.

The Amodei siblings — Anthropic CEO Dario Amodei and President Daniela Amodei — and five others will be the "sole members" of "Founder LLC," a new entity that will hold 50.1% of the voting power of the company's outstanding shares. The structure gives them "the ability to determine the outcome of all matters submitted to a vote of our stockholders generally for the foreseeable future," Anthropic said in its IPO prospectus on Monday.

The arrangement will also limit the power and influence of institutional and retail investors, who will have to put their trust in a small band of artificial intelligence engineers and researchers as the company marches toward a trillion-dollar-plus market cap. Anthropic has long tried to establish itself as the more safety conscious AI lab, and it's created a structure designed to give its founders the ability to preserve that long-term mission, even as it enters the world of quarterly financial reports.

"Our governance structure is likely to have the effect of limiting the likelihood of an unsolicited merger proposal, unsolicited tender offer, or proxy contest for the removal of directors," Anthropic said in the filing. "As a result, our governance structure may make it more difficult to replace our directors and management and may have the effect of depriving our stockholders of an opportunity to sell their shares at a premium over prevailing market prices."

Anthropic outlined what it described as a "novel capital and corporate governance structure" that has "no direct public company precedent."

It's another layer of complexity for investors to consider as they pore over the company's prospectus, which includes more than 90 pages of risk factors. Anthropic highlighted a number of political challenges , data center moratoriums and the company's effort to balance safety and commercial objectives as potential risks.

For some investors, founder control is a defining characteristic of generational tech companies.

Byron Deeter, a partner at Bessemer Venture Partners, told CNBC Monday that "when you have great leadership," investors are often comfortable giving early management and founders governance into the public market. Bessemer backed Anthropic at a $14 billion valuation, and Deeter said it's the biggest investment on a cost basis in the firm's 116-year history.

"There are some unusual elements to these things when they occur, but for category-defining, industry-defining opportunities, you want teams to be able to think long term," Deeter told CNBC's "Squawk on the Street" on Monday. "And there are a lot of benefits to being able to do that so teams can focus on true innovation, and not be month-to-month, or even quarter-to-quarter."
