Alphabet (GOOGL) Stock Drops 15% as Star AI Researchers Head for the Exit

TLDR

• Alphabet stock has dropped ~15% from its May highs above $400, including a single-day $225 billion market cap loss
• Addition to the Dow Jones Industrial Average failed to spark a recovery, with GOOGL falling another 1% after the announcement
• Key AI researchers including Nobel Prize winner John Jumper and engineering VP Noam Shazeer have left for rivals Anthropic and OpenAI
• Chinese AI firms like Z.ai are releasing competitive models at less than half the cost of American rivals, squeezing Alphabet from below
• Despite the pressure, Google Cloud grew 63% in Q1, Gemini hit 900 million users, and analysts have an average price target of $427.38

Alphabet (GOOGL) stock hit record highs above $400 in early May. It’s now down around 15% from those peaks, and the recent addition to the Dow Jones Industrial Average has done nothing to slow the slide.

Alphabet Inc., GOOGL

The most eye-catching moment came Monday, when Alphabet shed $225 billion in market capitalization in a single session — the largest one-day value loss in the company’s history. The stock currently trades around $341.77.

The Dow inclusion, announced late Tuesday, was supposed to be a vote of confidence. S&P Dow Jones Indices specifically cited Alphabet’s AI products and exposure to “dynamic areas of the U.S. economy” as reasons for the move. The stock dropped 1% the next day anyway.

That’s not entirely surprising. The Dow is a price-weighted index, meaning very few funds actually replicate its holdings. There’s no forced buying when a new name is added, unlike S&P 500 inclusions. Nvidia dropped 0.8% on its first day in the Dow in 2024. Amazon fell 0.1%. On average, stocks added to the Dow gain just 0.4% in the following 12 months, per Bespoke Investment Group.

AI Talent Drain Hits Google DeepMind

The bigger issue for Alphabet is who’s been walking out the door.

John Jumper, a Nobel Prize-winning senior research scientist at Google DeepMind, announced on June 19 he was leaving for Anthropic. That followed the departure of Noam Shazeer, VP of engineering, who is heading to OpenAI.

Shazeer’s exit stings twice. He originally left Google in 2021 — co-author of a foundational AI research paper — after the company wouldn’t release a chatbot he built. Alphabet spent $2.7 billion in 2024 to bring him back and license his startup’s technology. Now he’s gone again.

The timing is rough. Independent benchmarking from Epoch AI shows Google’s top AI models currently score slightly below the latest releases from OpenAI and Anthropic.

Chinese Rivals Add Pressure From Below

At the same time, Chinese AI firms are undercutting the market from the other direction.

Z.ai recently debuted in the global top three for large language model performance — the first Chinese company to reach that ranking — sitting ahead of any of Google’s current models. Companies like Z.ai, DeepSeek, and Alibaba are offering capable AI at less than half the cost of American alternatives.

That puts Alphabet in an uncomfortable position — squeezed between premium rivals at the top and cheaper Chinese models at the bottom.

Cloud and Search Still Delivering

The core business hasn’t fallen apart. Google Cloud grew 63% in Q1 2026, its strongest result since the division began reporting separately in 2019.

TD Cowen analyst John Blackledge projects cloud revenue growing at a 37% compound annual rate, from roughly $100 billion this year to $480 billion by 2031. His price target is $475.

Google Search traffic is at an all-time high. Gemini AI has 900 million users. And Alphabet’s custom TPU chips remain the most competitive alternative to Nvidia in the AI infrastructure market.

GOOGL currently trades at 23.6 times forward earnings, down from nearly 30 in February. The average analyst price target sits at $427.38, implying around 24% upside. Of 33 analysts tracked by TipRanks over the past three months, 28 rate it a Buy and five say Hold. None say Sell.
