Nebius Stock: Nvidia's 9.3% Stake, a Tel Aviv Software Buy and the 193% Run Into Year-End

Nebius acquires Tel Aviv startup Inferize to cut GPU idle time and inference costs, as shares close at EUR 215.65, up 193% this year.

The AI trade is quietly changing shape. For most of the past two years, the winning formula on Wall Street was simple: whoever locked up the most graphics processors set the terms. That logic is now bumping against its own arithmetic, because the enormous capital tied up in high-performance chips has to be paid for somehow.

The emphasis is shifting from raw capacity to utilization — what good are thousands of accelerators if they burn power in idle gaps between operations? That seam in the market is exactly where Nebius is positioning itself.

A ten-month-old startup with 17 employees

The neocloud specialist has agreed to acquire Inferize, a Tel Aviv-based firm founded just ten months ago that employs only 17 people but owns a software architecture capable of cutting GPU idle time and, with it, the cost of every individual AI query. Israeli media put the purchase price at between $100 million and $150 million; Nebius has not confirmed those figures. What the company has confirmed is that the technology and the entire engineering team have been folded into its Token Factory platform, aimed at strengthening inference infrastructure for production environments.

The strategic logic is straightforward. Nebius spent years riding headlines about gigantic data center builds. Now efficiency is becoming a matter of survival for infrastructure providers, since operating margin is decided in day-to-day running costs. Shaving inference expenses determines whether cloud customers can operate profitably over the long haul.

A rate-sensitive tape and a record Nasdaq

Investors got a reminder of how tightly the stock is wired to monetary policy. Weaker-than-expected US employment figures for September eased fears that the Federal Reserve would tighten again soon, and falling Treasury yields gave growth names a friendlier valuation backdrop. Reuters reported that the tech-heavy Nasdaq climbed to a record high on the wave of that relief, while AP noted that fading inflation worries lifted the broader US equity market.

Nebius rode the current, closing Friday at EUR 215.65 for a gain of 4.3% on the day. The advance leaves the shares up 193% since the start of the year and comfortably above their 50-day moving average of EUR 190.59. The session also underscored how sharply the stock reacts to policy signals from overseas: as long as rates support valuations, risk appetite in the tech sector remains a primary driver.

Nvidia at the register, Alabama in the courtroom

Adding weight to the bull case is a recently published report revealing that Nvidia holds a 9.3% stake in Nebius. The two companies cooperate across AI infrastructure, fleet management and inference. When the dominant chipmaker shows up as a major shareholder, it signals deep technological entanglement — an edge in a fiercely contested neocloud arena.

The physical buildout, however, cuts both ways. Data centers demand vast amounts of energy, land and permitting work, a reality Nebius is confronting in Alabama, where residents in Birmingham are fighting a planned complex in court. The project covers two buildings totaling roughly 450,000 square feet and would create 78 permanent jobs. Such clashes show that the digital expansion keeps running into very tangible local obstacles.

Separately, a regulatory filing disclosed that John Wilson Boynton IV sold 50 Nebius shares at $235.01 apiece.

What the premium has to prove

Wall Street remains optimistic about the challenger's strategic position despite the operational friction. The verdict on the AI infrastructure race, though, will no longer rest on who builds the biggest factories but on who manages existing compute most intelligently. Nebius is using the Inferize deal to close precisely that gap — and whether the rich price for a tiny developer team pays off will be measured in real cost savings for its customers.
