OpenAI has removed Sam Altman as the controller of its corporate venture fund due to concerns about the fund's unusual structure.

Ian Hathaway, a partner at the fund since 2021, assumes control following Altman's departure.

The OpenAI Startup Fund, under new management, has $175 million in backing from entities including Microsoft and has made investments in companies such as Harvey and Speak.

Despite removal from the fund, Altman recently profited $30 million from Reddit's IPO and continues to engage in significant investments.

OpenAI and Microsoft are collaborating on a significant $100 billion data center project featuring an AI supercomputer named 'Stargate'.

Separately, Altman's venture Worldcoin faces regulatory issues in Portugal, with a halt on data collection mandated over concerns of minors' data collection and insufficient data subject information.
