U.S. Senators Richard Blumenthal and Josh Hawley formally requested information from Alphabet CEO Sundar Pichai about how Google’s AI tools affect children’s mental health and education. The inquiry reflects growing regulatory scrutiny of AI’s role in daily life, particularly for younger users.

Separately, Pichai confirmed that Google Cloud is intentionally giving up some revenue to ensure DeepMind has the computing power it needs. He described the decision as “non-negotiable.”

Alphabet shares fell 2% even as the tech sector rose, as investors weighed the near-term revenue sacrifice against the long-term potential of Google’s AI ambitions. The decision underscores intense competition among major tech companies for AI computing resources.
