On November 18, 2025, Pichai warned that no company would be immune to an AI bubble burst, drawing parallels to the dotcom era while affirming AI’s long-term transformative potential [1]. Despite this warning, Alphabet (GOOGL) closed +3.11% at $285.02 with volume 53% above its 30-day average [0], outperforming the Technology sector (-0.31%) and Communication Services sector (-0.13%) [3].
