Anthropic has been working to give CEO Dario Amodei and the company's other co-founders a separate class of stock carrying extra voting power, two people familiar with the preparations said. The move is designed to shield the founding team from shareholder pressure as Anthropic prepares for what would be one of the largest technology IPOs in history.
The company filed confidentially for a U.S. IPO in June 2026, setting the stage for a public offering that would put its ownership structure under intense scrutiny. Anthropic's last primary funding round, completed in May 2026, set a post-money valuation of $965 billion. By mid-2026, shares changing hands on secondary markets implied a valuation above $1.2 trillion.
The supervoting architecture fits inside a governance framework Anthropic has built over several years. The company is structured as a public benefit corporation and operates with a Long-Term Benefit Trust designed to prevent any single investor from gaining full control. A multi-class share system gives founders and Trust-held Class B shares materially higher voting weight than the Class A equity held by institutional investors. Even with institutional ownership accounting for more than 60 percent of the economic stake, control rests with Dario and Daniela Amodei and the Trust.
That protection matters because the institutional stakes are enormous. Amazon is the single largest strategic investor, having committed more than $8 billion across multiple funding rounds. In Oct. 2025, Google expanded its own partnership by giving Anthropic access to as many as one million of its TPU chips—tensor processing units, Google's custom AI accelerators—a commitment worth tens of billions of dollars in compute value. Microsoft and Nvidia joined the cap table in Nov. 2025, committing up to $5 billion and up to $10 billion respectively. Total funding now exceeds $100 billion.
The corporate charter limits investor voting rights regardless of economic stake, meaning neither Amazon nor Google can force a sale or redirect the company's strategic priorities. Even with those combined commitments, neither holds a controlling position under the current structure. The incoming supervoting class would reinforce that arrangement post-IPO, when public shareholders would otherwise have the ability to agitate for changes in capital allocation or management.
The financial trajectory behind the IPO push is steep. Anthropic's annualized revenue run rate crossed $47 billion in May 2026, up from roughly $1 billion at the start of 2025. The growth was driven by API usage, enterprise contracts and Claude Code, the company's AI coding tool. The company employs roughly 5,000 people and has announced plans to nearly double that headcount by the end of 2026.
For each of the eight co-founders—referred to informally as the Anthropic Eight—the IPO math is striking. Forbes estimated that the eight founders each hold approximately 1.7 percent of Anthropic's shares. At a $1 trillion valuation, that translates to roughly $16.6 billion per founder in paper equity. Employees who joined as recently as spring 2025 have seen the paper value of their equity rise approximately 1,000 percent, according to people familiar with the cap table.
The product lineup behind those numbers is anchored by the Claude 4.5 model family, which includes Claude Opus 4.5 and Claude Sonnet 4.5. Claude is now available across all three major cloud platforms—AWS, Google Cloud and Azure—the first frontier model to achieve that distribution. The Microsoft deal that brought Claude to Azure was announced alongside Nvidia's investment in Nov. 2025. Anthropic also offers agentic tools including Claude Code and Cowork.
The safety-mission framing is structural, not just rhetorical. Anthropic was founded in 2021 by Dario Amodei, who serves as CEO, and Daniela Amodei, who serves as president, together with several colleagues who left OpenAI's research team. The company's published research includes work on constitutional AI—a method for training models using a set of written principles rather than purely human feedback—and model interpretability, which attempts to make the internal reasoning of large AI systems legible to outside researchers. The Long-Term Benefit Trust is the legal mechanism intended to keep that mission intact under capital pressure.
The tension that supervoting shares are meant to resolve is real. Amazon holds the largest single financial position in the company. Google's TPU commitment gives it leverage over compute access. Microsoft's Azure integration ties Claude distribution to a platform Anthropic does not control. Public markets would add another layer of shareholders whose incentives may diverge from the company's safety priorities. A dual-class structure—standard in large tech IPOs from Meta to Alphabet to Snap—gives founders the ability to take long-term research positions that quarterly earnings pressure would otherwise make difficult to sustain.
Anthropic competes directly with OpenAI, Google DeepMind and a smaller set of frontier model companies. The IPO, if it proceeds, would test whether public markets are willing to accept reduced governance rights in exchange for access to a company generating $47 billion in annualized revenue at a valuation that already exceeds most public technology companies.
