Klarna chief Sebastian Siemiatkowski has become the latest prominent artificial intelligence investor to warn against the tech industry’s multibillion-dollar dash to build data centres to power AI models.
Siemiatkowski — who holds shares in prominent AI companies including OpenAI, Perplexity, xAI and Cerebras through his family office Flat Capital — told the Financial Times that the huge sums being poured into computing infrastructure made him “nervous”.
“I think [OpenAI] can be very successful as a company but at the same time I’m very nervous about the size of these investments in these data centres,” he said. “That’s the particular thing that I am concerned about.”
