What Is Deferred Revenue? Why Prepaid GPU Cash Is Not Yet Earned
Deferred revenue is cash a company has already collected for a service it has not yet delivered. On a GPU cloud, the customer has paid and the cluster is still owed.
EXPLAINED · Mechanism · Last reviewed: 10 Nov 2026 · Next review: after CoreWeave’s Form 10-Q for the quarter ending 30 September 2026 and Nebius’s next interim financial statements
Deferred revenue is cash a company has already collected for a service it has not yet delivered. On a GPU cloud, the customer has paid and the cluster is still owed. The cash is a liability until that service is delivered.
In short. At 30 June 2026 CoreWeave’s deferred revenue was $9.7 billion, against $103.7 billion of remaining performance obligations. Nebius’s deferred revenue was $5,975.2 million, against $37,490.6 million of remaining performance obligations that leave out short contracts. Nebius expects to recognize its deferred balance over one to five calendar years, and the balance includes amounts that may be refundable. The stuck step is delivery. Collected cash is not earned revenue.
A signed book is a promise. Deferred revenue is the slice the seller has already been paid. The signed-book pages are remaining performance obligations and total contract value.
What is deferred revenue?
Deferred revenue is the seller’s liability for cash taken before the work is done. Nebius states the rule in the financial statements filed on 12 August 2026: the group recognizes deferred revenue when cash is received and before performance obligations are fulfilled, including amounts that may be refundable. The balances primarily relate to strategic customer agreements. The cash has arrived. The service has not. Some of the cash may have to go back.
CoreWeave’s Form 10-Q for the quarter ended 30 June 2026, filed the same day, does not reprint that sentence. It puts deferred revenue on the balance sheet, current and non-current, and it says remaining performance obligations include both billed and unbilled consideration. The billed amount not yet earned is the deferred-revenue line. The unbilled amount is still only a contract.
The clock is the service period, not the day the wire lands. Nebius says its deferred revenue is expected to be recognized over one to five calendar years. CoreWeave does not print a timetable for the deferred-revenue line alone. Its timetable is for the whole unsatisfied book, and that book runs out to month 78. Those clocks should not be swapped.
How is it different from a signed book?
Three figures sit near the word contract. They are not the same object.
| Term | Whose books | What has happened | What it is not |
|---|---|---|---|
| Deferred revenue | The seller, here the GPU cloud | Cash has been collected. The service has not been delivered | Not revenue, and not the whole signed book |
| Remaining performance obligation | The seller | A price is allocated to work not yet delivered. CoreWeave includes billed and unbilled amounts. Nebius also leaves out contracts whose original term is a year or less | Not cash in the bank |
| Purchase commitment | The buyer | A promise to pay a supplier later, often still off the balance sheet | Not money the seller has already collected |
A purchase commitment is the buyer’s promise. Deferred revenue is the seller’s liability after some of that promise has been paid. Take-or-pay is a third object: a promise to pay for reserved capacity once it has been delivered, used or idle. The buyer-side pages are purchase commitments and take-or-pay versus a purchase commitment.
Our arithmetic on CoreWeave’s rounded totals: $9.7 billion divided by $103.7 billion is 9.4%. CoreWeave does not print that share. The rest was still unbilled, or was variable consideration already netted out. The filing does not split those two.
Nebius says remaining performance obligations consist of deferred revenue plus unbilled contract revenue. Our arithmetic: $5,975.2 million divided by $37,490.6 million is 15.9%. That share is not comparable to CoreWeave’s 9.4%. Nebius excludes obligations whose original duration is one year or less. CoreWeave’s note does not. A higher share at Nebius is not, by itself, evidence that Nebius collects a larger fraction of its book up front.
What did CoreWeave and Nebius report at 30 June 2026?
Both filings are dated 12 August 2026. CoreWeave’s statements are in millions. Nebius’s are in millions of U.S. dollars. Line sums below are our arithmetic.
| CoreWeave | Nebius | |
|---|---|---|
| Deferred revenue, 30 June 2026 | $2,686 million current + $7,006 million non-current. The lines sum to $9,692 million. The note rounds that to $9.7 billion | $979.4 million current + $4,995.8 million non-current = $5,975.2 million |
| Deferred revenue, 31 Dec 2025 | $1,709 million + $6,476 million = $8,185 million. The note says $8.2 billion | $1,577.5 million |
| Revenue, quarter to 30 June 2026 | $2,575 million | $582.3 million |
| Revenue, six months to 30 June 2026 | $4,653 million | $981.3 million |
| Revenue in that half from deferred revenue that existed at the start | $554 million | $154.3 million |
| Unsatisfied remaining performance obligations | $103.7 billion. 41% expected over the 24 months to 30 June 2028, 39% in months 25 to 48, the rest in months 49 to 78 | $37,490.6 million. 36% over the 24 months to 30 June 2028, 40% in months 25 to 48, the rest after that. Short contracts are excluded |
CoreWeave’s balance rose by $1,507 million in the half ($9,692 million minus $8,185 million). Its cash-flow reconciliation shows a $1,365 million deferred-revenue item, against $743 million in the 2025 half. The filing does not bridge the $142 million. Nebius’s balance rose by $4,397.7 million, which matches $5,975.2 million minus $1,577.5 million. Operating cash was $4,504.1 million, driven primarily by customer advances, with a deferred-revenue increase of $4,395.0 million in that discussion. The $2.7 million gap between those two Nebius figures is not explained there.
Little of the half’s revenue was a release of last year’s prepay. CoreWeave recognized $554 million from the opening deferred balance, against $4,653 million of revenue. Our arithmetic: 11.9%. Nebius recognized $154.3 million from its opening balance, against $981.3 million. Our arithmetic: 15.7%. Most of the half’s revenue was earned inside the period. Nebius’s own clock for the deferred balance is one to five calendar years. CoreWeave has not published a recognition timetable for the deferred line alone.
Nebius’s shareholder letter, a separate 6-K the same day, describes deals closed in the quarter, not the audited balance. It says roughly 70% of deals closed included customer prepayments, covering 50% to 60% of the associated capital spending. That is the company’s description of its own quarter, not a financial-statement line, and not a finding about anyone else. The letter calls prepayment a market standard. That sentence is theirs.
Who gets paid — and where is the stuck step?
The customer has paid. The GPU cloud owes the service. CoreWeave’s cash was $5,524 million at 30 June 2026, against deferred revenue of $9,692 million. The prepay is not a sealed pile in an account. Nebius’s cash was $8,042.1 million against $5,975.2 million of deferred revenue.
The kit is paid for on a faster clock. In the half, CoreWeave spent $14,117 million of cash on property and equipment, including capitalized internal-use software. Net investing cash out was $14,874 million. Net financing cash in was $13,985 million. Cash interest paid, net of amounts capitalized, was $806 million. A supplemental line, not a cash total, records $9,796 million of liabilities for equipment additions, including OEM-financed additions. Our read: lenders and equipment sellers are paid while a large part of the customer contract is still unearned. The $1,365 million deferred-revenue item in operating cash is much smaller than the equipment cheques.
The hall is a separate bill. CoreWeave carried $16,595 million of operating-lease right-of-use assets and $15,735 million of non-current operating-lease liabilities. When the landlord’s bill starts is in data center leases. Nebius had paid $612.4 million toward leases, mainly facilities and equipment, that had not commenced. Those leases are expected to start in 2026 or 2027, on terms up to twelve years. The same note estimates $12,054.1 million of future undiscounted payments on them. That is not debt already drawn, and it is not customer deferred revenue.
Some prepaid cash has a coupon. Nebius’s interest expense was $182.8 million for the six months, covering convertible notes, interest on advances from major customers, and equipment received ahead of payment. The note does not split out the customer-advance piece.
The stuck step is the undelivered service. For many contracts the monthly bill waits on GPU cluster acceptance. Acceptance can start a bill. Nebius’s one-to-five-year line is the only explicit window, in these two filings, for how fast a prepaid balance becomes revenue.
What would change the view?
The next documents are CoreWeave’s Form 10-Q for the quarter ending 30 September 2026, and Nebius’s next interim statements. If the balance falls because opening deferred revenue is recognized as revenue, delivery is catching the prepay. A fall from a reclassification or a refund is a different event. If the balance rises, new prepayments outran delivery. Revenue can rise at the same time, as it did in this half.
A split that moves refundable amounts out of the line would shrink the liability with no cluster delivered. Nebius says the line may be refundable in part, and does not say how much. A CoreWeave timetable for deferred revenue alone, separate from the remaining-performance-obligation timetable, would change the clock. The letter’s 70% is a commercial claim. The audited balance is the test of how much cash is actually a liability.
Common misconceptions
- People read deferred revenue as revenue. It is a liability. CoreWeave’s revenue for the June quarter was $2,575 million. Its deferred revenue was $9.7 billion.
- People treat deferred revenue as the signed book. CoreWeave’s remaining performance obligations were $103.7 billion. Deferred revenue was the $9.7 billion already collected.
- People compare the two remaining-performance-obligation figures as one yardstick. Nebius leaves out contracts with an original term of one year or less. CoreWeave’s note does not state that exclusion.
- People treat a prepayment as cash the cloud has earned and may keep. Nebius says the balance includes amounts that may be refundable. The refundable share is not disclosed.
- People treat the prepay as the money that built the fleet. CoreWeave’s cash purchases of property and equipment were $14,117 million in the half. The deferred-revenue item in operating cash was $1,365 million. Financing covered the gap.
FAQ
What is deferred revenue?
Deferred revenue is cash a company has already collected for a service it has not yet delivered. On a GPU cloud it is a liability until the cluster is delivered and the service period runs.
Is deferred revenue the same as a remaining performance obligation?
No. A remaining performance obligation is the price allocated to work not yet delivered, billed or unbilled. Deferred revenue is the part the seller has already collected. At 30 June 2026 CoreWeave’s remaining performance obligations were $103.7 billion and its deferred revenue was $9.7 billion.
Why do GPU clouds collect cash before the cluster is live?
Nebius’s shareholder letter, filed 12 August 2026, says roughly 70% of the deals it closed that quarter included customer prepayments, covering 50% to 60% of the associated capital spending. That is one company’s description of its own deals. These filings do not show that every GPU cloud uses the same term.
Who gets paid first when a customer prepays a GPU cloud?
The customer has paid and is still owed the service. Equipment sellers, landlords and lenders can be paid before that service is revenue. At CoreWeave, cash equipment purchases in the first half of 2026 were $14,117 million, against a $1,365 million deferred-revenue item in operating cash.
Does a bigger deferred-revenue balance mean the cloud earned more?
No. A bigger balance means more cash has arrived for service that is still owed. In the first half of 2026 only $554 million of CoreWeave’s revenue, and $154.3 million of Nebius’s, came from the deferred balance that existed at the start of the year.
Is this a list of stocks to buy?
No. This page maps when cash moves and when it is earned. It is not a buy or sell call.

Markets and stack doors
Layer: Neoclouds. The liability sits with the GPU cloud, and lenders, equipment sellers and landlords can be paid sooner. Markets: United States, where CoreWeave files and where Nebius’s letter says construction is underway at owned AI factories. This site has no Netherlands door for Nebius Group N.V. Analysis: if a huge sum is owed before the cluster is accepted, where the cash sticks — the buyer’s promise. Deferred revenue is the seller’s line once part of that promise has been paid.

How we check this
CoreWeave figures are from its Form 10-Q for the quarter ended 30 June 2026, filed 12 August 2026. Nebius figures are from the unaudited statements and cash-flow discussion in the 6-K filed the same day, and from the shareholder letter filed that day. The percentages and the balance changes are our arithmetic on the companies’ lines. Where we judge which bill lands first, the wording says “our read”. The 70% term is Nebius’s description of its own quarter, not a financial-statement line. This page is not a buy or sell call.
