Alphabet's Q3 2026 earnings release on October 28 triggered the dominant driver of recent GOOGL price action, with revenue of $127.6 billion and adjusted EPS of $2.67 both missing consensus amid a slowdown in search advertising growth to 12% year-over-year. Google Cloud revenue more than doubled to $30.7 billion on AI demand, yet the company posted negative free cash flow of $9.1 billion from accelerated capital expenditures now guided at $195–205 billion for the full year and expected to rise significantly in 2027. This combination prompted a roughly 12.6% single-day decline on October 29, leaving shares trading in the $279–289 range through the first week of November amid elevated volatility and ongoing focus on AI monetization and margin pressures.
