The news yesterday confirmed that demand for cloud computing capacity remains strong. Investors sold the stock today after Nebius announced plans to raise $3.75 billion through new convertible note offerings and loans. That could lead to future dilution as well as further pressure on its financial strength.The capital raise shouldn’t come as a surprise, though, as the investing thesis for Nebius is to continue to build AI infrastructure to support deals like the one with Meta. The question will be whether it can get sufficient return on its investments in a timely period.
