Anthropic announced that all pre-IPO share transfers conducted via special purpose vehicle platforms are void because they lacked board approval [1].

The decision effectively nullifies a significant secondary market for the AI startup's shares. This move creates immediate financial uncertainty for investors who used these platforms to gain equity exposure before a public offering.

On May 18, 2024, the company listed eight distribution platforms on its website whose trades are now considered void [1]. Anthropic said the transfers violated its transfer-restriction clause since they were executed without the necessary authorization from the board [1].

The announcement sparked immediate alarm among retail and institutional investors. In one WhatsApp group, an investor asked, "Are we all ruined?" [1].

Special purpose vehicles are commonly used in the pre-IPO market to allow investors to pool funds and purchase shares from early employees or seed investors. However, these arrangements often clash with strict corporate bylaws that require company consent for any change in ownership. By invoking its transfer-restriction clause, Anthropic has asserted total control over its cap table, a move that protects the company's governance but leaves third-party buyers without legal claim to the shares.

Anthropic said that "stock transfers to SPVs are void according to our transfer restriction clause" [1]. The company did not provide a timeline for potential remedies or a process for investors to seek board approval retroactively.

This action signals that Anthropic is prioritizing strict governance and cap table cleanliness over the liquidity of its early secondary markets. By voiding these trades, the company prevents unauthorized entities from becoming shareholders, which simplifies the process for a future IPO. However, it also warns the broader AI investment community that SPV-based holdings in high-profile startups remain high-risk and subject to the unilateral discretion of the company's board.
