OpenAI is keeping busy.

Last week, the AI industry darling announced billions of dollars worth of deals and partnerships, signaling a massive push toward building out its infrastructure, strengthening its cloud capabilities and shoring up its push into the enterprise market.

In case you missed it, here’s the recap.

Though some fear that all of this hype may be heading toward a bubble burst (a narrative pushed by Altman himself), “what’s really happening is a massive infrastructure buildout that signals long-term commitment, not short-term froth,” said Jason Hardy, chief technology officer of AI for Hitachi Vantara. 

The race to build out this tech “resembles an arms race,” said Hardy, one that OpenAI sits at the forefront of. Although the market will likely experience corrections, Hardy noted that we are unlikely to see another dot-com bust. “There is too much enterprise momentum, and infrastructure is committed to its success.”

Despite its current frontrunner status, OpenAI’s moves could also highlight “significant overextension risks,” said Daniel Derzic, head of AI investments at Hartmann Capital.

“If funding slows, partnerships falter or regulatory scrutiny intensifies, the massive scale could become a liability, potentially squeezing out smaller competitors,” Derzic said.
