Nebius stock came under fresh pressure Monday after the AI cloud company completed a massive $5.75 billion convertible-note offering, giving it billions more to buy Nvidia GPUs and build data centers — but adding another layer of potential dilution and debt to one of 2026’s hottest AI infrastructure trades. The financing was expanded after investors exercised their full allotment, taking the final principal amount well above the $4.5 billion Nebius initially planned to raise.
NBIS shares were trading around $212 Monday afternoon, down roughly 3%, after already falling from $268.85 on August 17 to $219.13 by Friday. The sharp reversal shows the market’s dilemma: demand for Nebius AI capacity appears extraordinary, but financing that expansion is becoming almost as extraordinary as the growth itself.
Nebius Stock: What Exactly Did the Company Raise?
Nebius closed the transaction with $3.45 billion of 0.50% convertible senior notes due 2030 and $2.30 billion of 4.50% notes due 2034.
The total reached $5.75 billion because purchasers exercised their options in full for an additional $450 million of the 2030 notes and $300 million of the 2034 securities.
The original $5 billion transaction had already been upsized from $4.5 billion because of strong demand.

That demand is an important bullish signal in its own right: institutional investors were willing to provide Nebius with one of the largest convertible financings seen in the AI infrastructure sector. Reuters described the deal as one of the largest corporate convertible offerings in recent history.
Nebius intends to spend the proceeds on data-center construction, expanding its global infrastructure footprint, developing its full-stack AI cloud and buying GPUs and other critical components.
In other words, the money is not being raised to plug an ordinary operating shortfall.
Nebius is raising capital because customer demand is arriving faster than the company can build computing capacity.
The Conversion Prices Give Stock Some Breathing Room
The headline $5.75 billion figure sounds highly dilutive, but conversion does not occur anywhere near Monday’s share price under the initial terms.
The 2030 notes were originally priced with a conversion price of approximately $313.46 per share, representing a 40% premium to Nebius’s $223.90 closing price on August 19.
The 2034 notes carry an initial conversion price of approximately $324.65, or a 45% premium.
Those premiums matter.
Convertible debt gives investors bond-like downside protection while allowing them to participate if NBIS stock rallies enough. For existing shareholders, dilution becomes more relevant if Nebius’s share price moves significantly above those conversion thresholds.
The structure is even more nuanced because the principal amounts accrete over time.
At maturity, the 2030 notes are structured to reach 110% of original principal, producing an effective conversion price of about $344.81. The 2034 notes accrete to 125%, creating an effective price near $405.82.
That means the financing is not the equivalent of issuing $5.75 billion of stock at today’s price.
But it still creates meaningful future share-count risk if Nebius executes well enough to send its stock much higher.
A Separate Debt Exchange Creates Immediate Dilution
There is also another transaction investors should not confuse with the new convertible offering.
Nebius separately agreed to exchange $800 million of older convertible notes — $400 million of its 2029 notes and $400 million of its 2031 notes — for approximately 15.8 million Class A shares.
That exchange produces immediate equity issuance.
Reuters estimated the transaction represented roughly 5.5% dilution, while the company warned that participating holders could sell those shares or adjust hedge positions, potentially pressuring NBIS stock in the market.
That helps explain why the stock began falling before Monday’s closing announcement.
NBIS dropped nearly 10% on August 19 and another 1.7% the following session as traders digested the exchange and convertible financing.
Convertible buyers also frequently hedge by shorting the underlying stock, meaning part of the weakness can be technical rather than a direct vote against Nebius’s long-term business.
The Reason Nebius Needs So Much Money Is Simple: Capex Is Exploding
The financing becomes easier to understand when investors look at Nebius’s capital expenditures.
The company spent approximately $5.7 billion in Q2 alone, primarily on GPUs, related hardware and data-center expansion. That compares with quarterly revenue of just $582.3 million.
Nebius now expects $20 billion to $25 billion of capital expenditures in 2026.
That is an extraordinary investment burden for a company guiding to only $3.0 billion-$3.4 billion of full-year revenue.
This is the central financial debate around NBIS stock.
The company is constructing enormous amounts of infrastructure before the corresponding revenue is fully recognized.
If demand remains powerful and pricing holds, that upfront spending can generate spectacular future cash flows.
If demand weakens or AI compute prices collapse, shareholders could be left owning a highly capital-intensive company carrying substantially more debt.
Revenue Is Growing Even Faster Than the Financing
So far, operating demand supports management’s aggressive approach.
Nebius reported Q2 revenue of $582.3 million, up 454% year over year and 46% sequentially. Its core AI cloud business generated $574.9 million, representing 98% of group revenue and growth of 514%.
Annualized run-rate revenue reached $3 billion at the end of June, up from $1.9 billion at the end of March.
Even more importantly, adjusted EBITDA swung to $236.2 million, producing a 41% group margin, while the AI cloud business itself generated roughly 50% adjusted EBITDA margins.
Those figures are why the company can raise capital on unusually attractive terms.
The market is not financing a theoretical pre-revenue AI project.
Nebius is already selling essentially every unit of compute capacity it brings online.
Management said it was once again capacity constrained during Q2 because demand was absorbing infrastructure as quickly as it became available.
The $7 Billion-$9 Billion ARR Target Is the Real Bull Case
Nebius reaffirmed its goal of reaching $7 billion-$9 billion in annualized run-rate revenue by the end of 2026.
If achieved, that would imply another enormous acceleration from June’s $3 billion level.
Management also expects a full-year adjusted EBITDA margin around 40%.
That combination — hypergrowth plus unusually high infrastructure margins — explains why NBIS stock has risen so dramatically.
Nebius has also disclosed four major AI cloud deals signed during Q2 with an average contract size above $1 billion.
According to company materials, customer prepayments on those transactions are expected to finance approximately 50%-60% of associated capital expenditures, reducing the amount Nebius needs to fund from external debt or equity.
That is crucial.
If large hyperscaler contracts increasingly fund the hardware required to serve them, Nebius’s apparent capital intensity could become more manageable.
Microsoft and Meta Validate the Demand Story
The customer roster also gives Nebius unusual credibility for a comparatively young AI cloud provider.
The company has signed large agreements with Microsoft and Meta, including a Microsoft contract valued at roughly $17 billion and a Meta deal worth about $3 billion.
Those customers are among the biggest AI infrastructure spenders in the world.
Meta alone expects 2026 capital expenditures of $115 billion-$135 billion as it builds computing capacity for its AI ambitions.
Nebius therefore occupies a potentially lucrative position.
Hyperscalers require more GPUs and data-center capacity than they can always deploy internally, allowing specialized providers to absorb overflow demand.
That is effectively the neocloud business model.
If AI spending keeps expanding, Nebius may have years of demand ahead.
Nvidia Has Put Billions Behind Nebius Too
Another powerful vote of confidence comes from Nvidia.
Nvidia agreed in March to invest $2 billion in Nebius, acquiring an approximately 8.3% stake at the time as part of a broader partnership supporting the AI infrastructure buildout.
That relationship matters because Nvidia GPUs sit at the center of Nebius’s capital requirements.
Nebius needs reliable access to advanced accelerators, while Nvidia benefits when AI cloud providers aggressively build clusters around its hardware.
The strategic alignment does not eliminate execution risk.
But Nvidia’s investment gives Nebius a level of industry validation that many smaller AI infrastructure companies lack.
The Debt Load Is Becoming Impossible to Ignore
The bearish argument is straightforward: Nebius may be growing quickly, but its balance sheet is accumulating obligations nearly as quickly.
Reuters estimated that the new financing takes Nebius’s total convertible debt to roughly $12 billion.
That comes alongside the $775 million asset-backed facility Nebius announced in July.
The secured facility is backed by GPU infrastructure and contracted customer cash flows and carries pricing of SOFR plus 2.5%. Nebius says the structure covers more than 100% of the capital expenditure required for the underlying deployment.
That financing is arguably healthier than unsecured corporate borrowing because it directly matches debt with contracted infrastructure.
Nebius also says it has more than $40 billion of additional customer commitments that could support similar financing structures.
But investors should still monitor total leverage, interest expense and future refinancing needs carefully.
AI infrastructure is becoming a debt-funded arms race.
The Asset-Light Strategy Could Change the Equation
Nebius is already attempting to reduce that capital burden.
In July, the company introduced a model in which infrastructure partners finance and own AI data centers while Nebius supplies its architecture, hardware designs, software stack and sales platform.
Nebius says the structure could create a high-margin revenue stream with minimal incremental capital requirements.
If that model scales, it could fundamentally improve the NBIS investment case.
Instead of financing every GPU cluster itself, Nebius could monetize its software and operating expertise across infrastructure paid for by outside investors.
That would move the business toward a more capital-efficient platform model.
The catch is that the approach remains relatively new.
Investors still need evidence that partner-owned capacity can grow quickly enough to materially reduce Nebius’s dependence on convertible debt and equity issuance.
Outlook: Is the Financing Bullish or Bearish for NBIS Stock?
The $5.75 billion raise is both.
It is bullish operationally because Nebius has secured the capital needed to meet AI demand that management says continues to exceed available supply.
It is bearish financially because shareholders now face more debt, potential future conversion and near-term technical selling from the separate 15.8 million-share exchange.
The crucial numbers to watch are no longer simply quarterly revenue.
Investors should track year-end ARR against the $7 billion-$9 billion target, total capex versus the $20 billion-$25 billion plan, customer prepayments, new asset-backed financings and whether adjusted EBITDA margins remain near 40%.
Nebius has shown that it can find customers.
Now it must prove it can finance their demand without permanently overwhelming existing shareholders.
The $5.75 billion question for Nebius stock is no longer whether the AI boom is real — it is whether NBIS can build fast enough to capture it before the financing bill catches up.
