• Anthropic’s seven founders will hold 50.1% of shareholder voting power through a special Class F share, even if they sell most of their economic stakes.
  • The structure, combined with a Long-Term Benefit Trust that elects a board majority, gives public investors economic exposure with limited governance influence.
  • The IPO filing reveals explosive revenue growth but also massive infrastructure commitments and governance risks that could weigh on shareholder value.

A Governance Structure Unlike Any Other

Anthropic’s founders are set to maintain ironclad control over the artificial intelligence company for decades after its initial public offering, according to the firm’s newly unveiled IPO filing. The seven founders, including CEO Dario Amodei and President Daniela Amodei, will collectively control 50.1% of shareholder voting power through a single Class F share held by Anthropic Founders LLC. That share carries no economic rights and cannot be diluted by future stock issuance.

The structure allows founders to sell or donate up to 98% of their IPO-era stockholding while still retaining eligibility to vote the Class F share, provided other conditions are met. As long as at least three founders remain, the group retains majority voting power. Departing founders can be replaced by successors admitted until 10 years after the IPO, according to reporting on the filing, though the precise terms could not be independently verified. A separate Long-Term Benefit Trust, which holds a Class T share, elects a majority of the board. Public Class A shareholders receive one vote per share but will have little ability to influence shareholder-vote outcomes while the founder structure operates.

“What institutional investors like us are really focused on is regulatory stability,” said one person familiar with the matter, echoing concerns that the dual-class structure may deter some public-market investors. “This is a governance framework designed to insulate decision-making from short-term market pressures.”

Explosive Growth, Enormous Obligations

The governance news comes as Anthropic’s financials reveal staggering growth. Revenue for the first half of 2026 reached $16.29 billion, up from approximately $1.16 billion a year earlier—a fourteenfold increase. Full-year 2025 revenue was $4.59 billion. The company reported an operating loss of $693 million for the first half of 2026, a sharp improvement from the $8.06 billion operating loss for all of 2025. However, a net loss of $80.7 billion for the first half included a $72.4 billion accounting charge related to convertible notes, not cash consumed by operations.

Anthropic’s business is heavily usage-based, with consumption charges accounting for 80% of first-half revenue. More than 1,900 customers generated at least $1 million each in trailing-12-month revenue as of September 30. The company has committed more than $500 billion in spending with six partners over roughly a decade, including at least $110 billion with Amazon (AMZN), about $114.5 billion with Google (GOOGL), and $44.9 billion with Microsoft (MSFT). Many agreements include non-cancelable payments, creating substantial fixed obligations if demand disappoints.

The Trust and the Mission

The Long-Term Benefit Trust, which elects a board majority, has added prominent outside figures: former Federal Reserve Chair Ben Bernanke joined in June, and Harvard physicist Christopher Stubbs joined this month. Anthropic also placed approximately 5% of its shares into a Public Benefit Fund. The company plans to list on Nasdaq (NDAQ) under the ticker “ANT” and remain a public benefit corporation.

A spokesperson for Anthropic said the structure “ensures that our mission to develop safe and beneficial AI remains central to every decision, even as we access public capital.” The company declined to comment on specific voting thresholds.

Risks and Regulatory Hurdles

The filing identifies several risks, including data-center moratoriums in 16 states, concentration of advanced-chip manufacturing in Taiwan, and trade restrictions. Overseas revenue reached $4.5 billion, or 27.8% of first-half sales. Anthropic acknowledges that its safeguards are incomplete and cannot guarantee protection against serious misuse.

The IPO will test whether public investors accept limited voting influence in exchange for exposure to Anthropic’s growth. The company warns that its structure could reduce demand for its shares, increase volatility, and generate governance litigation. A filing is not a completed offering, and valuation ambitions should not be treated as established public-market value.

What to Watch

Investors will scrutinize the trust’s independence and the founders’ ability to replace departing members. The interplay between the founder-controlled shareholder vote and the trust’s board appointments could create friction, particularly if the company faces a crisis. For now, the message is clear: Anthropic’s founders intend to steer the company for decades, regardless of how much stock they sell.

Correction: An earlier version misstated the minimum retained ownership required for founder eligibility. It is 2% of IPO-era stockholding, not 5%.
