Each firm told investors a similar story: private equity, the business of buying companies with debt, was their speciality.Yet as the economy recovered, private-markets firms flourished—emerging as the new kings of Wall Street. The biggest put more and more money into credit, infrastructure and property. By 2022 total assets under management had reached $12trn. Those at Apollo, Blackstone and have risen from $420bn to $2.2trn over the past decade.
