Nebius Stock: A $399 Target, an $84 Warning and the Price Hikes in Between

BNP Paribas Exane upgraded Nebius to Outperform with a $399 target; Rothschild & Co Redburn initiated at Sell with $84, a roughly $315 gap.

Two analyst notes landed within 48 hours of each other this week, and they could hardly disagree more about what Nebius is worth. BNP Paribas Exane upgraded the stock from Neutral to Outperform, attaching a $399 price target. Rothschild & Co Redburn had only just initiated coverage on Tuesday — with a Sell rating and a target of $84.

That gap, roughly $315 wide, captures the market's genuine confusion over how to value a company riding the artificial intelligence infrastructure boom.

A stock caught between two extremes

Investors in Europe clearly leaned toward the bulls. The shares climbed 7.3% in the previous session to close at EUR 213.60, and the rally has been running all year — Nebius is up 191% since January. A separate reading of the advance puts the year-to-date gain at 195%, reflecting the stock's sharp moves from one session to the next.

The bull case rests on a straightforward premise: demand for AI computing capacity keeps outstripping supply, and Nebius sits on the right side of that imbalance. Sceptics counter that the sector looks overheated and that margins will come under pressure before long.

Pricing power on display

The operating story got fresh ammunition from a Reuters report that Nebius will raise its flexible usage rates for selected Nvidia chips starting October 1. Certain graphics processor tariffs are going up by 17% to 21%. The increases cover Nvidia's top-tier accelerators — the H100, H200, B200 and B300 — while some AMD processors face surcharges of around 25%.

This is the second round of price hikes in three months, a signal that management feels confident enough to charge more rather than simply chase volume. Such moves only stick when customers are desperate for turnkey infrastructure and alternatives are thin on the ground. Nebius appears to be blending long-term contracts with large customers alongside spot business at much higher rates, capturing predictable baseline utilization on one hand and maximum margin during demand spikes on the other.

The numbers back it up. Second-quarter 2026 results showed cloud revenue of $574.9 million and an adjusted operating margin of just under 50%. SemiAnalysis also ranks Nebius at Platinum status in its Neocloud league table, ahead of much of the competition.

Insiders head for the exits

Not everyone is holding. Corporate insiders have been selling into the rally through pre-arranged trading plans. SEC filings show that in mid-September, director John Wilson Boynton IV offloaded 6,364 Class A shares across multiple open-market transactions. Chief Revenue Officer Marc Boroditsky exercised options on 7,000 Class A shares and sold the entire position in the market. Both sales were executed under Rule 10b5-1 automated plans.

The selling coincides with the widening split among research houses. BNP Paribas Exane is betting Nebius can place its capacity at highly profitable rates; Rothschild & Co Redburn's far lower target signals deep doubt about whether the current valuation can hold.

What the next quarters must prove

Between those two poles, the stock's direction will hinge on concrete operational data. How fully are the data centers utilized? Will customers keep paying after the October price adjustments take effect? And can the company execute on its enormous buildout without stumbling over the capital-intensive nature of the business — delays from external partners or power connections have derailed rivals' timelines before.

Prominent bears are watching closely. Investor Michael Burry has been building short positions across the sector, wagering on falling chip prices. Combined with the insider sales, that's a reminder that position sizing matters even for those convinced by the growth story.

For now, the evidence tilts toward the operator that can push through double-digit price increases and still fill its order book. Whether that justifies a $399 valuation or something closer to $84 is the question the market has yet to settle.
