Robin Khuda, the chief executive of data centre giant AirTrunk, is no stranger to rapid growth; he started the business in 2015 and it is now said to be worth as much as $10 billion. But even he can’t quite believe how the artificial intelligence boom is changing his business.

A few years ago, a big deal could see AirTrunk sign up a client who needed five megawatts of capacity; each megawatt is worth between $15 million and $20 million.
