Nebius Shares Hit Records on Reports of AI21 Labs Talks

The possible deal signals a move up the AI stack that could test ties with Nvidia.

Overview

  • Shares of Nebius set fresh highs this week after multiple outlets reported the company is in talks to buy AI21 Labs, an Israeli startup that builds language models for businesses.
  • Cantor Fitzgerald initiated coverage with an Overweight rating and a $129 target, adding to bullish attention that also includes Buy targets from BofA at $150 and BWS at $200.
  • Nebius is scaling fast on the ground, including a planned 310 MW AI data center in Lappeenranta, Finland, and a goal to secure more than 3 GW of contracted power by the end of 2026.
  • Long-term demand and funding are in place, with a reported $27 billion compute agreement with Meta ($12 billion over the next five years) and a $4 billion convertible-notes sale completed in early 2026.
  • Any acquisition could be complex because Nvidia has invested in both Nebius and AI21, and earlier Nvidia–AI21 talks collapsed after valuations were reported in the $2 billion to $3 billion range.
