Sep 11, 2025
Nebius Group has raised $3.75 billion through convertible notes and stock sales to expand its AI infrastructure, following a significant partnership with Microsoft.

Nebius Group has successfully raised $3.75 billion through a combination of convertible notes and stock offerings. This financial move comes shortly after the company secured a major contract with Microsoft Corporation, valued at up to $19.4 billion, to provide AI infrastructure from its new data center in Vineland, New Jersey.

The funds raised will be used to enhance Nebius's computing power and hardware, secure strategic land plots, and expand its data center footprint globally. The company aims to support its growth in the AI sector by catering to both AI startups and larger enterprises.

The convertible notes were issued in two tranches, with maturities in 2030 and 2032, and the stock was offered at $92.50 per share. Nebius plans to use the proceeds to finance its ongoing expansion and general corporate purposes, positioning itself as a key player in the AI infrastructure market.
