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.

The trading platform said Monday it has launched US stock and ETF tokens in the European Union at an event in Cannes, France. European Robinhood customers will have access to more than 200 US stock and ETF tokens. Stock token holders will also receive dividend payments directly in their Robinhood app.
