Amazon AI Chief Rohit Prasad to Leave as Andy Jassy Puts AWS Veteran Peter DeSantis in Charge of AGI, Nova Models, Chips and Quantum

December 18, 2025 — Amazon is reshaping its artificial intelligence leadership at a moment CEO Andy Jassy calls an “inflection point,” moving longtime AWS executive Peter DeSantis into a newly expanded organization that brings together Amazon’s most ambitious AI model work, custom silicon development, and quantum computing efforts. The change comes as Rohit Prasad, the senior vice president and head scientist who helped build Alexa and later led Amazon’s “AGI” organization, plans to depart at the end of 2025. About Amazon+1

As of 6:00 p.m. ET on Wednesday, December 17, 2025, Big Tech stocks finished the U.S. session broadly lower, with the AI trade back in the crosshairs.

Big Tech Stocks Today (Dec. 17, 2025): Magnificent Seven Slide on AI Infrastructure Jitters as Amazon–OpenAI Talks and Fed Rate Outlook Take Center Stage

Big Tech stocks are setting the tone for U.S. markets on Wednesday, December 17, 2025, with the “Magnificent Seven” trade showing fresh signs of stress even as the sector’s long-term AI narrative keeps expanding.

NEW YORK — December 16, 2025 — AI stocks are trading on two competing forces in Tuesday’s U.S. session: renewed skepticism about whether massive AI infrastructure spending can translate into profits fast enough, and a fresh set of macro signals that could shape the interest-rate path into 2026. After a delayed November jobs report surprised investors with a higher unemployment rate alongside stronger job creation, major U.S. indexes turned lower through midday trading. Investopedia+1

Amazon Stock After Hours: AMZN Ticks Up Post-Bell on Dec. 15, 2025 — What to Watch Before Tuesday’s Open

Amazon.com, Inc. closed out Monday’s regular session lower, then edged higher in after-hours trading — a familiar pattern when investors are waiting for a major catalyst rather than reacting to a single, company-specific headline.
