Apple's biggest developer event of the year kicks off Monday, and for the first time in a long time, the pressure isn't really about hardware.

WWDC starts June 8, and Apple confirmed the keynote will lean heavily on software and AI. That's where the company has been bleeding goodwill for over a year. Apple Intelligence launched to a polite shrug, the personalized Siri overhaul promised at WWDC 2024 slipped, and Tim Cook told CNBC that a more personalized Siri was "on track to launch" this year. Monday is the part where he has to actually show it.

What makes this year different is that Apple has finally stopped pretending it can do this on its own. In January, the company and Google confirmed that Apple Foundation Models, the brains behind Siri and most of Apple Intelligence, will run on a custom version of Google's Gemini. The joint statement was blunt by Apple standards: the next generation of Apple Foundation Models would be "based on Google's Gemini models and cloud technology."

That's a notable thing for the most vertically integrated company in tech to say out loud. Dan Ives, a senior equity analyst at Wedbush Securities, put it on CNBC this way: "From Apple's perspective, it's certainly a win if you think about the pain that they've had in their AI strategy up to this point." Apple overpromised in 2024, couldn't deliver, and is now buying its way out of the foundation model problem. The win is that Siri might finally work. The loss is that the thing making it work isn't theirs.

Here's what the keynote is expected to cover, based on rumor roundups from MacRumors and CNET:

  • The Siri overhaul, finally: A more conversational assistant that can pull personal context from your apps and take actions on your behalf. This is the thing Cook promised in June 2024 and has been apologizing for ever since.
  • On-device AI as the pitch: Expect Apple to lean hard on the idea that your data stays on your phone, an obvious counterweight to Gemini running in the background.
  • iOS 27 and a redesign: The bigger annual software refresh, where the new Siri will live alongside whatever else Apple wants developers to start building against.

Sitting under all of this is a quieter transition. In April, Apple announced that Cook will step aside and John Ternus, the longtime hardware engineering chief, will become CEO on September 1. Cook stays on as executive chairman. The handoff caught a few analysts off guard, including Wedbush's Dan Ives, who told CNBC that the consensus view was Cook "was going to stay on maybe for another year." Instead, Ternus is taking over in three months, which means WWDC is essentially Cook's last big keynote as CEO and Ternus's first real introduction to the people who will judge him.

INTO THE VALLEY:

The story Apple wants to tell on Monday is that the delays were worth it, that the Gemini deal is a strategic choice rather than a concession, and that Siri is finally about to be the assistant it was always supposed to be. The story the keynote will actually tell is whether that's true. Apple has 2.2 billion active devices and a customer base that has been remarkably patient about a year of unmet promises, but patience isn't infinite, and the company is handing the keys to a new CEO in September with the AI bet still unproven. If Ternus inherits a Siri that works, the Gemini partnership looks like a smart trade. If he inherits another set of "coming later this year" slides, it's going to be a long fall.
