Anthropic just issued a pretty serious investor alert. They’re basically saying: if you buy their private shares without board approval, they won’t recognize you as a shareholder. The transaction simply won’t count.
In the notice they called out several platforms where unauthorized shares are being offered.
They also warned against SPVs, tokenized securities, forward contracts, or any clever workarounds trying to bypass their transfer restrictions.
Why are they doing this? Demand for Anthropic shares is exploding (rumors of a new funding round that could value the company near $900 billion), and they want to keep full control over who gets into their cap table. Classic big AI company move — protect the ownership structure at all costs.
