Robinhood just launched a new ventures vehicle and Stripe could be "supposedly" part of it. Robinhood Ventures Fund I (RVI),

Thank you for sharing this, I was unaware! It launches tomorrow.

This is the footnote regarding Stripe: "New deal incoming: RVI has entered a binding agreement to invest in Stripe, Inc. This investment is expected to close after RVI’s IPO, subject to meeting customary closing conditions. Note: This deal isn’t guaranteed to close."
