Nebius's Capital Blitz and the Price of AI Compute: A Story in Three Acts

Nebius shares drop 24.6% post-Q2 despite strong AI compute auction prices and $5.75B convertible, as dilution concerns weigh.

There's a particular kind of tension that builds when a company's operational story and its stock price tell different tales. For Nebius Group, that tension has rarely been more visible than over the past fortnight. The Amsterdam-based AI infrastructure player has closed a blockbuster convertible bond sale, secured shareholder backing for fresh equity flexibility, and watched its shares slide anyway.

The market's skepticism isn't about the business itself. It's about the bill that comes with it.

The Auction That Changed the Math

The most telling data point in Nebius's recent history didn't come from an earnings call or a boardroom — it came from a capacity auction held two weeks before the convertible placement closed. The company's first auction for medium-term contracts cleared at prices 15 percent above any rate Nebius had previously charged, and 20 percent above the current pipeline pricing for Nvidia's Blackwell chips.

That's not a rounding error. It signals genuine scarcity in AI compute — the kind of pricing power that turns infrastructure bets into cash-generating machines. If Nebius can consistently sell compute at a premium, the billions it's raising start to look like a rational investment rather than a leap of faith.

The follow-through came last week when Nebius closed its convertible bond placement at $5.75 billion gross — comfortably above the $4.5 billion originally targeted. The deal split into two tranches: $3.45 billion with a 0.50 percent coupon maturing in 2030, and $2.3 billion carrying a 4.50 percent coupon with a 2034 maturity. Goldman Sachs and JPMorgan led the transaction, and Reuters characterized the strong demand as evidence of investor appetite for AI services and data center capacity rather than a mere financing exercise.

Upsizing a deal by more than 25 percent mid-bookbuilding says something about what the company believes it can do with the money — and what lenders believe it can achieve.

Shareholder Rubber Stamp, Strategic Flexibility

Tuesday's annual general meeting delivered the second pillar of this strategy. Shareholders approved every resolution on the table: the reappointment of Arkady Volozh and Ophir Nave as executive directors, confirmation of the nominated non-executive directors, approval of the 2025 annual accounts, and discharge of the board.

The more consequential item was the five-year authorization for the board to issue additional Class A shares up to 20 percent of issued capital, excluding Class C shares. On its own, that's administrative routine. In the context of the convertible, it reads as a deliberate hedge: Nebius is building optionality across both debt and equity, ensuring it can fund growth without returning to capital markets at an inopportune moment.

The Q2 numbers from roughly two weeks ago provided the foundation for this capital activity. Revenue came in at $582.3 million, with the company reaffirming its full-year guidance of $3.0 to $3.4 billion and an ARR target of $7 to $9 billion. For 2026, Nebius expects customer prepayments totaling $9 billion and pointed to four contracts each averaging over $1 billion. The company also raised its contracted power capacity target to 5 gigawatts by year-end — up from 4 gigawatts targeted in May and 3 gigawatts in February.

The Market's Verdict

None of that has stopped the sell-off. Since the Q2 report, the stock has fallen 24.6 percent. Even Citigroup's price target raise to $324 with a maintained buy rating — published the same day as the earnings — couldn't stem the tide; shares have lost 18.4 percent since that call.

The market's reaction isn't to weak operations. It's to the financing structure. The convertible announcement triggered concerns about dilution and rising leverage, and those concerns have persisted through the placement's completion.

Friday's close of €180.72, down 3.6 percent on the day, tells the story. The stock has shed 3.7 percent over the week and now trades below its 50-day average of €189.85. That pattern has held since the quarterly numbers: strong operational signals — auction prices above prior-year levels, an expanded capacity target — but a share price that struggles to convert those signals into sustained upward momentum.

The market has already priced in a significant degree of confidence in the AI infrastructure story. What it wants now is evidence that the capital intensity — funded through billions in convertibles and potential equity dilution — will translate into actual cash flows.

The central question isn't the next price level. It's whether the scarcity in compute capacity translates into durable pricing power, or whether the auction was a one-off outlier in a still-young market. That distinction determines whether the current consolidation is a pause or a re-rating.
