Summary
According to a report from the Equable Institute, a public pension research organization, nearly 20 public pension funds have exposure to Anthropic ahead of the AI company's planned initial public offering. Equable identified more than 18 public funds that are limited partners in Spark Capital's funds, which hold Anthropic shares, and 28 possible public funds that are limited partners in Insight Partners XII, whose manager invests in Anthropic, though not through all of its funds. Equable's analysis of Anthropic's S-1 filing with the Securities and Exchange Commission found a half-dozen private funds managed by Spark Capital among entities holding more than 5% of the company's shares before the offering.

Anthropic is targeting a valuation of up to $1.4 trillion in the IPO, scheduled for Thursday, November 19. The company will offer 825 million shares priced between $70 and $78 each, with approximately 6% of total shares floating publicly.

Among the disclosed Spark Capital commitments, the Texas County & District Retirement System has committed $210 million across three funds, the South Carolina Retirement System Investment Commission $110 million across two funds, the Massachusetts Pension Reserves Investment Trust $104 million across three funds, and the Orange County Employees' Retirement System $101.6 million across three funds. Other pensions with Anthropic exposure through Spark include the California State Teachers Retirement System, the Los Angeles City Employees' Retirement System, the Maryland State Retirement and Pension System, the Washington State Investment Board, and the Nebraska Investment Council. Randazzo noted that public disclosure has been limited, and that only the North Carolina state treasurer and the New York City comptroller had publicly acknowledged Anthropic holdings.

Equable estimates that 35.1% of U.S. public pension public equity holdings are invested in AI-related companies, representing about $578 billion in exposure. Randazzo said nearly every public pension plan will become an owner of Anthropic within months, either through internal index-building strategies or passive index funds that must buy the stock once it joins most U.S. equity indexes, given its size. The Equable report concludes that public plans will own Anthropic "whether they want to or not," adding to portfolios already concentrated in AI.
