Nebius Secures $5 Billion in Convertible Bond Offering

On August 20, Nebius Group (NASDAQ:NBIS) confirmed a $5 billion convertible bond offering, a significant move that has been sending shockwaves through the market. This massive deal is one of the largest in recent corporate history, and it has sparked both excitement and concern among investors.

The company increased the initial deal size from $4.5 billion late Wednesday, and the total could still grow to $5.75 billion if buyers exercise every option attached. Nebius claims that the sheer size of the raise is proof of the high demand for its AI computing capacity. However, the stock’s reaction to this news has been far from encouraging, with a sharp drop over two sessions.

Bull Case: Betting on Insatiable Demand

Nebius chief communications officer Tom Blackwell summed up the company’s pitch succinctly: ‘We know that everything we build, we can sell several times over.’ This statement is backed by the company’s impressive sales figures, which have been surging rapidly in recent quarters.

Nebius sells AI computing power to prominent customers such as Meta and Microsoft, and its results demonstrate that the shortage in AI computing capacity is real rather than temporary. In the second quarter, the company’s sales skyrocketed by 454% year-over-year to $582 million, exceeding analyst estimates and solidifying its position in the market.

Wall Street analysts expect the pace of revenue growth to continue, with forecasts calling for 446% growth in the third quarter and 526% in the fourth. This remarkable growth has been driven by Nebius’s expanding data center footprint throughout the year.

Nvidia, the chipmaker at the center of the AI buildout, holds a roughly 9.3% stake in Nebius, a sign of confidence in the company’s growth prospects. This has fueled a wild ride for Nebius shares, which have climbed more than 220% year-to-date and jumped over 40% in just the past few weeks, largely on the strength of the second-quarter report.

The Cost of Growing Fast

However, the dilution math is what actually moved the stock. Alongside the convertible note offering, Nebius disclosed a deal to swap $800 million of previously issued convertible notes for 15.8 million new shares, diluting existing holders by roughly 5.5%. This news sent shares down as much as 14% intraday on Wednesday before they closed down 10.03% at $223.51, with trading volume swelling to 48.8 million shares, about 129% above its three-month average of 21.3 million.

This is Nebius’s third capital raise this year, and its total convertible debt now stands around $12 billion. The spending matches the borrowing: capital expenditures hit $5.7 billion in a single quarter, and Nebius posted a net loss of $190 million even as revenue surged. None of this cash has turned into profit yet, and some analysts see an uncomfortable parallel to the broader capex race among the biggest AI infrastructure spenders, questioning how long the financing can keep pace with the building before something has to give.

A Market Split Down the Middle

Hedge fund ownership of Nebius rose to 60 funds in the most recent quarter from 54 previously, pointing to institutions adding exposure even through the volatility. Short sellers, on the other hand, see it differently, with 27.60% of the float sold short, a level that signals a substantial bear camp positioned against the stock.

This combination is the kind of setup that can send a stock sharply higher on good news or sharply lower if growth disappoints.

What the Next Quarter Decides

Nebius has turned fundraising into a near-constant event this year, and each time the market has to decide whether that reflects strength or strain. The bull case rests on demand still outrunning supply badly enough that a $5 billion bond sells easily and gets upsized along the way. The bear case rests on a debt load and dilution pattern that is growing just as fast as the revenue meant to justify it.

For the growth story to win out, that 454% revenue growth pace needs to hold up long enough to make today’s spending look prescient rather than reckless.
