It exists outside of Robinhood:

- Sofi: https://www.sofi.com/invest/fractional-shares/

- Schwab: https://www.wsj.com/articles/schwab-in-bid-for-younger-clien...

I'm not totally sure how it's structured, but I imagine RH "owns" the shares and offers you the corresponding fractional amount of value/dividends, etc.

Folio has been doing it for over a decade (https://www.folioinvesting.com/folioinvesting/brokerage-feat...)

Square's Cash App permits fractional share purchases, as well.

Note that Schwab has announced it, but it's not available yet.
