Alphabet Loses $500 Billion in Market Value Following Third-Quarter Earnings Miss

Alphabet suffered a historic single-day market capitalization loss of $500 billion following disappointing quarterly financial results that heightened volatility across mega-cap technology shares. The sell-off was triggered after the company reported third-quarter revenue of $127.58 billion, falling short of analyst expectations of $128.20 billion, alongside earnings per share of $2.12. Alphabet's stock initially plunged nearly 10% in after-hours trading before the steep single-day valuation drop materialized.
