OpenAI warns consumers that Robinhood's sale of "OpenAI tokens" will not give them equity or stock in the company.

Robinhood earlier this week announced it would give away to eligible European users small "tokenized" stakes in private companies OpenAI and SpaceX, an offering OpenAI said it did not endorse.

OpenAI has condemned online brokerage firm Robinhood's sale of "OpenAI tokens," saying they will not give consumers stock in the company.
