Alphabet Loses $505 Billion in Historic Market Crash

Alphabet Inc. suffered its largest single-session market capitalization loss in history, falling below a $4 trillion valuation and dropping to fourth most valuable company globally.

Alphabet Inc. lost $505 billion in market capitalization on Thursday, marking the largest nominal and percentage decline in the company's history. The stock fell 12.6% in a single session, pushing the company's total valuation below $4 trillion.

This collapse shifted the global rankings of the world's most valuable companies. Microsoft surpassed Alphabet to claim the third position, trailing only Apple and Nvidia. The sell-off comes as Alphabet continues to invest heavily in its artificial intelligence infrastructure, specifically its Gemini large language models and Tensor Processing Unit chips.

Financial analysts indicate that the company's free cash flow yield has dropped to 0.6%. This creates a higher risk profile for investors than in previous market downturns, as Alphabet's future growth is now heavily dependent on the commercial success of its AI investments.
