OpenAI and Anthropic Synchronize Ban on Unauthorized Equity Transfers
OpenAI announced a formal policy on its official website today, stating that all equity transfers without written consent are invalid, covering direct sales, SPV shares, tokenized rights, and forward contracts.
Anthropic's policy is more aggressive, using "void" instead of "voidable," specifically naming platforms such as Open Door Partners, Unicorns Exchange, Forge Global, and Hiive, stating that shares purchased through these channels carry no shareholder rights.
Both companies plan to IPO in Q4 of this year, aiming to clean up their equity tables of uncontrolled "wild shareholders" and secure pricing power before going public.

OpenAI had publicly warned investors about unauthorized SPV scams as early as August 2025, and this formal policy represents a tightening of equity control following its shift to a for-profit structure. Anthropic quickly followed suit after a $380 billion Series A financing in February 2026, continuing its tradition of strict board approval since its inception.
In terms of capital pathways, both companies are using the "void" clause to shift secondary market trading resources from uncontrolled platforms and SPVs to internally recognized channels, motivated by the need to lock in shareholder structures for the IPO roadshow while preventing valuation bubbles from harming primary investors' interests, thereby strengthening the priority of strategic shareholders like Microsoft and Amazon.
Similar to the early strict restrictions on secondary trading by Meta and SpaceX, the current AI unicorns are in a control phase transitioning from high-valuation private stages to public markets. Anthropic's secondary valuation has soared to about $1 trillion, far exceeding its primary valuation.
Essentially, this is about capital concentration and the transfer of pricing power: equity control is shifting from dispersed secondary buyers to the company's board of directors. The mechanism is the absolute effectiveness of the "void" clause under Delaware corporate law, allowing the company to clean up its capital table before going public while internalizing excess secondary premiums by prohibiting indirect rights, providing certainty for IPO pricing.

Cleaning up "wild shareholders" before the IPO shifts pricing power back to the founders. The higher the secondary premium, the more the primary must be locked down; control is the true valuation anchor. Invalid transactions are legally "as if they never happened"; capital will always chase structures with exits.
