The artificial intelligence boom that Sam Altman helped ignite with ChatGPT in late 2022 is starting to make even him uneasy.
Startups with little more than a pitch deck are raising hundreds of millions. Valuations have become "insane." Capital is chasing a "kernel of truth" with feverish speed.
The OpenAI CEO still believes the long-term societal upside of AI will outweigh the froth, and he's ready to keep spending in pursuit of that goal.
"Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes," he said at a recent dinner with reporters. "Is AI the most important thing to happen in a very long time? My opinion is also yes."
He repeated the word 'bubble' three times in 15 seconds, then half-joked, "I'm sure someone's gonna write some sensational headline about that. I wish you wouldn't, but that's fine."
While Altman warned that valuations are now out of control, he's ready to shell out on more infrastructure.
"You should expect OpenAI to spend trillions of dollars on datacenter construction in the not very distant future," Altman said. "And you should expect a bunch of economists wringing their hands, saying, 'This is so crazy, it's so reckless,' and we'll just be like, 'You know what? Let us do our thing.'"
OpenAI is already looking beyond Microsoft Azure's cloud capacity, and is shopping around for more.
The company signed a deal with Google Cloud this spring and, according to Altman, OpenAI is "beyond the compute demand" of what any one hyperscaler can offer.
"You should expect us to take as much compute as we can," he added. "Our bet is, our demand is going to keep growing, our training needs are going to keep going, and we will spend maybe more aggressively than any company who's ever spent on anything ahead of progress, because we just have this very deep belief in what we're seeing."
It's not just OpenAI. All the megacaps are trying to keep up.
In their most recent earnings, tech's biggest names all raised capital expenditure guidance to keep pace with AI demand: Microsoft is now targeting $120 billion in full-year capital expenditures, Amazon is topping $100 billion, Alphabet raised its forecast to $85 billion, and Meta lifted the high end of its capex range to $72 billion.
