Nebius Prices $4 Billion Convertible Notes for AI Data Center Expansion

Nebius Group has priced $4.0 billion in convertible senior notes through a private offering, directing the capital toward AI data center construction, cloud development, and GPU procurement in one of the largest infrastructure financing rounds of 2026.

The company announced on March 18, 2026 that the deal was upsized from a previously announced $3.75 billion target to $4.0 billion in aggregate principal. The offering is structured as two tranches: $2.25 billion of 1.250% notes due 2031 and $1.75 billion of 2.625% notes due 2033.

Nebius estimated approximately $3.96 billion in net proceeds from the sale. If the initial purchaser fully exercises its additional purchase option, that figure could reach $4.55 billion. Settlement is expected on March 20, 2026.

The notes are being sold to qualified institutional buyers under Rule 144A and will not be registered under the Securities Act. They carry conversion premiums of 57.5% and 55.0% above the March 17 closing price for the 2031 and 2033 tranches, respectively.

NBIS shares closed at $118.56 on the day of the announcement, up from an open of $114.84, on session volume of 18.67 million shares. The positive equity reaction suggests investors viewed the terms favorably despite the dilution risk that convertible instruments carry.

Why Convertible Notes Suit a Capital-Intensive AI Buildout

Convertible notes blend debt financing with the option for holders to convert into equity at a future date. For a company scaling compute-heavy infrastructure, this structure offers lower coupon rates than traditional bonds while deferring potential dilution.

The 1.250% and 2.625% rates on Nebius’s two tranches are modest relative to the scale of capital raised. That pricing reflects investor willingness to accept lower yields in exchange for equity upside if Nebius’s AI infrastructure bet pays off.

Nebius stated that proceeds will fund data center construction and build-out, expansion of its data center footprint, AI cloud development, GPU procurement, and general corporate purposes. Each of those line items requires significant upfront spending before generating revenue, making convertible debt a practical match. Companies pursuing AI-driven commercial infrastructure across sectors face similar capital allocation decisions as the technology scales.

The structure also gives Nebius flexibility on timing. Unlike a straight equity raise, which locks in dilution immediately, convertible notes push that decision to bondholders and to future share price performance. If the stock appreciates well beyond the conversion premiums, holders convert; if not, Nebius repays the debt.

What a $4 Billion Raise Signals for AI Infrastructure Competition

A single financing round of this size dedicated to AI data center capacity underscores how aggressively companies are moving to secure compute resources. Demand for GPU clusters and purpose-built AI facilities continues to outpace supply, and Nebius is positioning itself to capture a share of that market.

The upsizing from $3.75 billion to $4.0 billion is itself a signal. Investor appetite exceeded the original target, indicating strong institutional conviction that AI infrastructure spending will deliver returns over the five-to-seven-year maturity window of these notes.

This financing round lands during a period of broader macroeconomic caution. The Federal Reserve’s decision to hold rates steady has kept borrowing costs elevated across sectors, making Nebius’s ability to raise $4 billion on convertible terms notable. The company secured capital at relatively low coupon rates even as inflation concerns persist and risk appetite in adjacent markets has cooled.

In crypto markets, the contrast is visible. Bitcoin traded at $71,283 on March 18, down 4.39% over 24 hours, while the Crypto Fear and Greed Index sat at 26, firmly in “Fear” territory. Traditional AI infrastructure equity, meanwhile, attracted fresh capital.

The notes are senior unsecured obligations, meaning they rank above equity but below any secured debt in Nebius’s capital structure. For institutional buyers, that positioning offers a balance between downside protection and exposure to AI-sector growth.

Nebius has not disclosed specific data center locations or GPU procurement partners tied to this raise. The company’s next public disclosures will likely provide more detail on how the capital is being deployed and on what timeline facilities are expected to come online.
