Alphabet shares fell 5% on Monday, marking the company’s largest single-day decline in more than a year and erasing approximately $225 billion in market value as investors reacted to growing competition for artificial intelligence talent among major technology companies.
The decline followed reports that Noam Shazeer, one of the co-leads behind Google’s Gemini AI model, is leaving Google DeepMind to join OpenAI, the company behind ChatGPT. The move highlights the increasingly competitive environment among technology firms seeking to attract and retain leading AI researchers and engineers.
Shazeer’s departure comes only a few years after his return to Google through a transaction involving Character.AI, the startup he co-founded. In 2024, Alphabet entered into a multibillion-dollar agreement with Character.AI that brought Shazeer back to the company as part of its broader artificial intelligence strategy.
The stock’s decline represented Alphabet’s steepest percentage loss since May 2025 and its largest single-day reduction in market capitalization on record, according to market data cited by MarketWatch and Dow Jones Market Data.
Alphabet was not alone in Monday’s selloff. Shares of other large technology companies also moved lower as investors assessed spending plans and competitive developments across the AI sector. Microsoft shares fell 3% after announcing plans to build a new data center campus, while Meta Platforms declined 2% following corporate restructuring efforts involving WhatsApp.
Separately, Alphabet announced that Google DeepMind will collaborate with independent film studio and distributor A24 on artificial intelligence research initiatives that could eventually support areas including content creation and film production. The company also disclosed plans to invest in A24, although financial terms were not officially released.
According to a report by The Wall Street Journal, the investment is expected to total approximately $75 million.
The partnership reflects ongoing efforts by technology and entertainment companies to explore potential applications of artificial intelligence across media production, content development, and creative workflows. Recent years have seen increased investment activity linking AI developers, streaming platforms, and entertainment companies as the technology becomes more integrated into production processes.
Alphabet’s latest market decline comes amid heightened competition among technology companies seeking leadership positions in the rapidly evolving artificial intelligence industry. The company continues to invest heavily in AI infrastructure, research, and product development as competition intensifies across both consumer and enterprise markets.
