There are bad weeks, and then there is whatever just happened to Google's AI division. Picture missing a public deadline, watching four star employees stroll out the door, and shedding a quarter-trillion dollars in value — all inside roughly six days. It reads less like a news cycle and more like a curse someone bought at a yard sale.

The Model That Didn't Show Up

On June 24, Alphabet confirmed that Gemini 3.5 Pro would not reach public general availability in June, missing the commitment CEO Sundar Pichai made on stage at Google I/O on May 19. The model remains stuck in a limited Vertex AI enterprise preview for now, visible but not quite reachable.

On paper, Gemini 3.5 Pro is a monster: a 2-million-token context window and a Deep Think reasoning mode that sounds genuinely formidable. But a model that almost nobody outside an enterprise preview can actually touch does very little to counter the growing narrative that Google has lost a step in a race it once led.

A Talent Exodus With Famous Names

The delay would sting a lot less if the people who build these models had stuck around. Instead, four senior DeepMind researchers departed between June 18 and 24 — including Noam Shazeer, a Transformer co-author and Gemini co-lead, who reportedly left for OpenAI.

The other exits did not exactly soften the blow: Nobel laureate and AlphaFold lead John Jumper, plus two more Gemini specialists, all reportedly headed to Anthropic. When the architects walk off the site mid-build, investors tend to start asking pointed questions about the scaffolding.

$269 Billion Is a Lot of Vibes

And ask they did. Alphabet shed roughly $269 billion in market capitalization across sessions from June 18 to 24, as the market repriced one simple, uncomfortable question about the whole enterprise.

That question, paraphrased: if you are spending around $190 billion on AI infrastructure but losing the people who make that infrastructure produce frontier results, what exactly are you buying? Compute is purchasable with a big enough checkbook; the talent that knows what to do with it is decidedly not.

Google still has staggering resources and a deep bench, so writing the obituary now would be premature and probably foolish. But for one brutal week, the search giant looked less like the odds-on favorite and more like the team mumbling through what went wrong in the post-game presser.
