Google Keeps Losing Top AI Researchers to Anthropic and OpenAI
Google is losing its best people. In just one week, several of its top AI researchers (the scientists who build smart computer programs) have quit. Most of them went straight to two rivals: Anthropic and OpenAI. One of them even won a Nobel Prize. Others helped build Gemini, Google’s main AI. Bloomberg reported this on June 24, 2026. The news even made Alphabet’s stock price fall, because investors got worried. (Alphabet is the company that owns Google.)
Why does this matter? In AI, people are the product. The best researchers build the best AI. When they leave, they take their rare skills and ideas with them.
Who is leaving and where they are going
The list of names is big. Jonas Adler and Alexander Pritzel are both leaving for Anthropic. They were key people on Gemini. Adler worked on AI that helps write computer code. Pritzel worked on training Gemini’s AI. (Training means teaching an AI by feeding it lots of data.)
The biggest name is John Jumper. He is a Nobel laureate. (A laureate is someone who has won the prize.) He won the 2024 Nobel Prize in Chemistry. He shared it with Demis Hassabis, the boss of Google DeepMind. They won it for AlphaFold, an AI that predicts the shape of proteins. Jumper was a director at DeepMind. He is also going to Anthropic.
Noam Shazeer has gone to OpenAI. He was a co-lead on Gemini. (A co-lead is one of the people in charge.) His story has a twist. He once started a company called Character.AI. Google bought it back for about $2.7 billion, and that brought Shazeer back to Google. Now he has left Google again.
Key facts: the departures
| Researcher | Old role at Google | New home | Date |
|---|---|---|---|
| Noam Shazeer | Gemini co-lead | OpenAI | June 18, 2026 |
| John Jumper | DeepMind director, Nobel laureate (AlphaFold) | Anthropic | June 20, 2026 |
| Jonas Adler | AI coding for Gemini | Anthropic | June 24, 2026 |
| Alexander Pritzel | Training Gemini AI systems | Anthropic | June 24, 2026 |
Why are they leaving?
Money and timing are big reasons. Both Anthropic and OpenAI are getting close to an IPO. (An IPO, or Initial Public Offering, is the first time a company sells its shares to the public. It can make early staff very rich.) To pull people in, these firms offer big equity packages. (Equity means a share of the company that you own. So workers get a piece of the company, not just pay.)
The flow is mostly one way. A study by SignalFire looked at this. It found that DeepMind engineers move to Anthropic about eleven times more often than Anthropic staff move to DeepMind. That is a huge gap.
How is Google responding?
Google is trying to calm the worry. DeepMind CEO Demis Hassabis said Google still has “the deepest research bench of any AI lab.” In plain words, he means Google has so many smart people that losing a few will not break it. Still, losing this many stars in one week is rare. And it happened in public.
There is also a reason beyond money. At a smaller, newer lab, a star researcher can have more say over the next big AI. Many top scientists want to be where the action is. They want to shape a frontier model from the start. (A frontier model is one of the most advanced AI systems. It pushes the limits of what AI can do.) A small lab can offer that focus more easily than a giant like Google.
Why one week of exits rattled investors
Losing one researcher is normal. Losing several of your most important people in one week is not. That is why the news hurt Alphabet’s stock. Investors worry about two things. First, Google may fall behind in the AI race if its best minds keep leaving. Second, the exits show that rivals now feel strong enough to take people from the very top.
The Gemini link makes it sting more. Adler, Pritzel and Shazeer all worked on Gemini, Google’s top AI. When the people who built your best product join rivals, those rivals gain more than talent. They gain inside knowledge too. That is a real, lasting risk for Google.
FAQ
Why is Google losing AI researchers?
Rivals Anthropic and OpenAI are close to their IPOs. They offer big equity packages, which means a share of the company. That pulls top people away.
Who is the most famous researcher to leave?
John Jumper. He won a Nobel Prize for the AlphaFold AI. He is moving to Anthropic.
Did this hurt Google’s stock?
Yes. Bloomberg reported that the exits scared investors and pulled down Alphabet’s stock.
Why it matters (especially for India and founders)
The fight for AI talent is global, and India is part of it. Many of these top researchers are Indian-origin or work with India-linked teams. The lesson for Indian founders is clear. The best people now have huge bargaining power. (Bargaining power means how much you can ask for and still get.) To keep them, startups must offer real ownership, not just salary. This race for talent is shaping which AI models win. That includes the ones competing on cost and quality and the agentic tools Indian users are demanding. For India’s growing AI scene, this is a chance to attract returning talent with equity and bold projects.
The takeaway: AI’s future is being decided by a small group of brilliant minds. Right now, more of them are picking Anthropic and OpenAI over Google. Money, IPO riches, and the chance to shape a frontier model are pulling them away. The war for AI talent has only just begun.
