Nebius Rises 4% Despite Adding $5.75B in Convertible Debt, Snapping a Six-Session Slide

Nebius Group (NASDAQ:NBIS | NBIS Price Prediction) stock is up 4% to $218.47 Tuesday midday, snapping a six-session losing streak that had built as the market braced for a large convertible deal. The rebound arrived right after the company disclosed a raise that came in larger than the market had expected. Year to date through Monday’s close, Nebius Group stock was up 152%, so the recent slide interrupted a strong 2026 run.

For context, the First Trust Cloud Computing ETF (NASDAQ:SKYY) is down 0.1% to $158.77 in Tuesday trading, drifting as software names cool off. Meanwhile, Global X Data Center & Digital Infrastructure ETF (NASDAQ:DTCR) is up 2% to $28.53, tracking a firmer bid across data-center REITs and semiconductor names tied to AI buildouts.

Bigger Raise Draws Bigger Demand

Nebius announced Monday the closing of a private offering of convertible senior notes with aggregate gross proceeds of approximately $5.75 billion, sold to qualified institutional buyers. The deal came in two series: 0.50% convertible notes due 2030 with $3.45 billion in aggregate original principal, and 4.50% convertible notes due 2034 with $2.3 billion in original principal. Initial purchasers exercised their options in full for an additional $450 million of the 2030 notes and $300 million of the 2034 notes.

The total exceeded Nebius’s initial $4.5 billion target, which had been raised to $5 billion last week. Investors appear to be reading the upsize as validation of demand for the company’s AI infrastructure buildout, which is anchored by long-term contracted capacity (we profiled seven suppliers powering that buildout, from power to cooling, in a free report you can grab here). Order books that clear at a higher size and a low 0.50% coupon on the front tranche suggest institutional appetite for exposure to neocloud growth.

Dilution Stack Grows Alongside Backlog

Alongside the new offering, Nebius entered privately negotiated exchange agreements with certain holders of its 2.00% convertible notes due 2029 and 3.00% convertible notes due 2031, swapping $400 million of the 2029 notes and $400 million of the 2031 notes for approximately 15.8 million Class A ordinary shares. The company disclosed that those holders may sell the shares in the open market or unwind hedge positions, activity that “could decrease (or reduce the size of any increase in) the market price of the Class A shares.” The exchange effectively swaps a portion of the older notes for equity ahead of their scheduled maturities.

Proceeds from the raise will fund data-center construction and build-out, investment in its full-stack AI cloud, expansion of its data-center footprint, procurement of GPUs and other key components, and general corporate purposes, according to the company. Long-term committed capacity contracts represent $37.5 billion in remaining performance obligations, and three customers each represent more than 10% of quarterly revenue. That concentration cuts both ways, providing visibility while tightening the company’s reliance on a handful of anchor tenants.

Neocloud Peers Set the Frame

The bull case rests on customer demand. Nebius signed a five-year, $12 billion AI infrastructure deal with Meta Platforms (NASDAQ:META) and is targeting 800 MW to 1 GW of connected power by the end of 2026, with data center campuses in Missouri, Pennsylvania, Finland and the United Kingdom. That contract sits inside the $37.5 billion of remaining performance obligations that the raise is designed to fund.

CoreWeave (NASDAQ:CRWV) is the closest listed comparison for Nebius, running the same neocloud playbook with heavy capex, hyperscaler-anchored contracts, and its own large convertible-supported balance sheet. IREN Limited (NASDAQ:IREN) rounds out the neocloud trio, and IREN reports fiscal fourth quarter 2026 results after the close on Thursday, August 27, giving the group its next fundamental checkpoint. Both peers face the same capital-intensity math that Nebius does, which is why the group tends to trade in sympathy on financing news.

What to Watch

Traders can watch for whether the Nebius stock rebound holds into today’s close and how the new 2030 and 2034 notes trade against the existing convertible stack. Sizing matters here, since the raise concentrates dilution risk even as it clears near-term financing uncertainty.

The IREN earnings report Thursday will give investors the next read on neocloud demand and capex pace across the group. Investors should size their positions to reflect the capital intensity of the model and the customer concentration in Nebius’s book, especially after a session where good news arrived wrapped inside a $5.75 billion debt raise.
