Robinhood’s stock hit record highs with its crypto token launch, but shares slid after OpenAI denied involvement, warning the tokens aren’t legitimate equity.

Robinhood stock popped this week on news that European users could trade "tokenized" stock in private companies. OpenAI distanced itself from the plan.

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