Take a read through the 10-K for the NYSE's parent company, Intercontinental Exchange, Inc.: https://www.sec.gov/Archives/edgar/data/1571949/000157194922000006/ice-20211231.htm https://www.sec.gov/Archives/edgar/data/1571949/000157194922... OP is wrong though. Their entire data and hosting revenue is $838m, but more traditional listing and transaction fees make up the rest of their $3.8b revenue. So basically 20% data and hosting, 80% classic exchange profit: https://www.sec.gov/Archives/edgar/data/1571949/000157194922000006/ice-20211231_g12.jpg https://www.sec.gov/Archives/edgar/data/1571949/000157194922...
