Alphabet Stock Drops 5% After Four Top Google Researchers Leave in One Day

tags. We'll translate the text inside. Let's do it carefully. Original content:

Alphabet shares fell as much as 5% on Wednesday after four of Google's most-cited researchers quit on the same day. The stock closed at $360.71, down 3.9% from Tuesday's close of $375.35, wiping out roughly $190 billion in market value. At its lowest point, the stock hit $355.16, erasing as much as $260 billion from the company's $4.61 trillion market cap.

Translation: "Акції Alphabet впали на 5% у середу після того, як четверо найбільш цитованих дослідників Google звільнилися того ж дня. Акції закрилися на рівні $360,71, що на 3,9% нижче від закриття вівторка на рівні $375,35, що стерло приблизно $190 мільярдів ринкової вартості. На найнижчій точці акції сягнули $355,16, втративши до $260 мільярдів з ринкової капіталізації компанії у $4,61 трильйона." We need to use Ukrainian formatting for numbers: use comma as decimal separator? Actually in Ukrainian, decimal comma is used, but for currency, often they use period? Typically in Ukrainian, decimal numbers use comma, but for large numbers, spaces or periods? We'll keep as in original with $ and numbers, but we can use comma for decimals: $360,71? Actually in Ukrainian, it's common to write $360.71 with a period? But in Ukrainian texts, they often use comma for decimals. However, to be safe, we can keep the original format with period, but it's acceptable. We'll use comma for decimals: $360,71? But the original has $360.71. I'll keep the period as is, since it's a currency amount and it's common to use period in financial contexts. But to be natural, we can use comma. Let's decide: In Ukrainian, decimal separator is comma, but for currency, sometimes they use period. I'll use comma for decimals: $360,71, $375,35, $355,16, $190 мільярдів, $260 мільярдів, $4,61 трильйона. But we need to be consistent. I'll use comma for decimals and space for thousands? Actually, in Ukrainian, thousands are separated by space or period? Usually space. But we have $190 billion - we can write $190 млрд. We'll keep numbers as in original but with Ukrainian formatting: $360,71, $375,35, $355,16, $190 млрд, $260 млрд, $4,61 трлн. But the original has "billion" and "trillion" - we'll translate to "мільярдів" and "трильйонів". Also "market cap" - "ринкова капіталізація". Let's write the translation. Next paragraph:

Who left and where they're going

Хто пішов і куди вони прямують

Jeff Dean, Google's chief scientist and a 27-year veteran, is leaving to co-found Discovery Loop, a public benefit corporation focused on automating machine learning, science, and engineering. Dean joined Google in 1999 as its 30th employee and co-created MapReduce and Bigtable. He is joined by three other researchers: Sanjay Ghemawat, Oriol Vinyals, and Quoc Le. Discovery Loop says it has three of the most-cited AI researchers and two of the most-cited in distributed systems.

Demis Hassabis is stepping away from daily control of Google DeepMind. He becomes chairman of DeepMind and chief scientist of Alphabet, while continuing to lead Isomorphic Labs. Koray Kavukcuoglu takes over as senior vice president of DeepMind, responsible for Gemini model development, frontier research, and the Gemini app.

Why the market reacted

Чому ринок відреагував

Investors saw the departures as a blow to Google's AI leadership. The stock remains about 11% below its 52-week high of $404.47. A similar event happened on June 22, when Alphabet closed 5.1% lower after two researchers left: Noam Shazeer (to OpenAI) and John Jumper (to Anthropic). Shazeer was the second of eight authors on the 2017 transformer paper; Jumper shared the 2024 Nobel Prize in Chemistry with Hassabis.
