Nebius Surges on Reported AI21 Talks in Push Toward Full-Stack AI

A deal would pair its fast-growing data-center business with in-house AI models.

Overview

Nebius shares rose about 33% for the week on reports it is in talks to buy Israeli AI startup AI21.
The Information reported the talks, and AI21 chairman Amnon Shashua said the company explored sale options after late-stage negotiations with Nvidia collapsed.
Nebius has a $2 billion investment and technology partnership from Nvidia that it says will speed its next-generation AI cloud buildout.
Meta agreed to buy $27 billion of Nebius compute capacity over ten years, with $12 billion in the first five years and $15 billion in the next five.
Nebius is targeting about 3 GW of contracted power this year, including a 1 GW site in Missouri and a 310 MW development in Finland slated to be fully online next year.
