What do you mean? I was under the impression that including SPCX has been massively beneficial for Nasdaq. It creates lots of trading volume and sends a quiet signal to other massive tech companies looking to IPO to come to them, rules be damned. So they're definitely extremely lucrative for Nasdaq.
I the short term. Who knows what the damage to the brand will cost them.
Having the stock traded on their board is good for them. They also maintain an index. Elon made inclusion in the index a prerequisite for trading the stock on the board.
It created basically the volume of the index funds buying the required stock, and it's not yet clear what kind of signal this has sent to people.
They got mostly the money SPCX paid them. It was a large payment but not out of the ordinary. And all that they risked was their index relevancy.
