Revenue Backlog vs RPO: What's the Difference?
Revenue backlog is a company’s own total of future revenue under committed contracts. RPO is the accounting remainder. On 30 September 2026 CoreWeave printed $132.5 billion and $132.3 billion.
EXPLAINED · Versus · Last reviewed: 13 Nov 2026 · Next review: after CoreWeave’s report for the quarter ending 31 Dec 2026, which should reprint revenue backlog and remaining performance obligations
Revenue backlog is a company’s own total of the revenue it expects to recognise later under committed contracts. Remaining performance obligation, or RPO, is the accounting remainder: the price allocated to work that has not been delivered yet.
In short. The two numbers are two prints of future revenue. At CoreWeave on 30 September 2026, revenue backlog was about $132.5 billion and unsatisfied RPO was $132.3 billion. The $0.2 billion between those rounded prints, by our arithmetic, is an estimate the company adds on top of the accounting remainder. Deferred revenue of $10.0 billion sits inside the RPO. At IREN the prints part, because most of the backlog is a lease book kept outside RPO.
Why an investor cares: the press release carries the company’s wrapper, and the filing carries the accounting remainder. Our total contract value Explained covers the signed book. Our remaining performance obligation Explained covers RPO as the hyperscalers report it. This page compares the two prints on the neoclouds layer.
What is the difference between revenue backlog and RPO?
Revenue backlog is a label the company writes. RPO is the remainder the accounting rules require for work not yet delivered.
CoreWeave’s results release of 10 November 2026 says revenue backlog includes remaining performance obligations, plus other amounts it estimates it will recognise later under committed customer contracts. Both parts wait on delivery and on the service being available. IREN’s results release of 5 November 2026 uses that shape and adds remaining lease arrangements. RPO itself is measured in the quarterly report.
What does CoreWeave count in each print?
On 30 September 2026 CoreWeave’s revenue backlog was approximately $132.5 billion and its unsatisfied RPO was $132.3 billion. Our arithmetic on those rounded figures puts the prints $0.2 billion apart. The release does not name the “other amounts” in that gap.
The Form 10-Q, filed on 12 November 2026, defines RPO as the transaction price, net of estimated variable consideration, allocated to performance not delivered or only partly delivered. CoreWeave’s variable consideration is its estimate of future service credits, of revenue it may miss because delivery is late, and of committed capacity it has the right to resell. RPO includes billed and unbilled amounts.
The committed contracts are take-or-pay. They accounted for 98% of revenue in the quarter, including capacity delivered before a commitment’s start date. Our RPO vs take-or-pay page separates the accounting remainder from that contract form.
A few deals are leases, with CoreWeave as lessor, under ASC 842. Lease income in the periods shown was not material. The contracted value of those leases was about $0.3 billion. That book sits outside RPO. It is close to the $0.2 billion gap, and the filing does not say the two figures are the same dollars.
Where does deferred revenue sit?
Deferred revenue is cash, or a bill, collected before delivery. It is a balance-sheet liability, and it sits inside RPO, because CoreWeave’s RPO includes billed and unbilled consideration.
On 30 September 2026 deferred revenue was $2,269 million current and $7,733 million non-current. The lines add to $10,002 million, which the note states as $10.0 billion. Our arithmetic: that is 7.6% of the $132.3 billion RPO. Subtracting it from the $132.5 billion backlog would invent a gap of $122.5 billion. The printed gap is about $0.2 billion.
During the quarter, $462 million of revenue was recognised from deferred revenue already on the books at the start. That is 12.6% of the quarter’s $3,661 million of revenue, by our arithmetic. Another $1.9 billion of the opening deferred-revenue balance moved to customer liabilities, inside other current liabilities, because contracts became cancellable. The filing states that move. It does not say whether those dollars also left RPO.
Why is IREN’s backlog larger than its RPO?
Most of IREN’s book is a lease, and a lease is not a remaining performance obligation under ASC 606.
The 5 November 2026 release put revenue backlog at $20.3 billion, up 22% from the prior quarter. The footnote includes remaining performance obligations, remaining lease arrangements, and other amounts the company estimates may be recognised later, each of them subject to delivery and availability.
The Form 10-Q gives the first two pieces. ASC 606 remaining performance obligations were $6,347 million: $1,529 million expected within 12 months, $1,652 million in months 13 to 24, and the rest in months 25 to 60. The rest is $3,166 million, by our arithmetic. The figure includes $50 million for the financing component on upfront prepayments. The remaining contracted value of lease arrangements, including capacity the customer cannot use yet, was about $13,957 million.
$6,347 million plus $13,957 million is $20,304 million, which rounds to the $20.3 billion backlog. Our arithmetic leaves no material third bucket on these prints.
| CoreWeave, 30 Sep 2026 | IREN, 30 Sep 2026 | |
|---|---|---|
| Revenue backlog | About $132.5 billion | $20.3 billion |
| RPO | $132.3 billion | $6,347 million under ASC 606 |
| Outside the RPO | About $0.2 billion of other estimates on the rounded prints. Leases of about $0.3 billion are disclosed separately | Leases of about $13,957 million. Added to RPO, the lines match the backlog |
| Deferred revenue | $10.0 billion, inside a book that includes billed amounts | $2,544 million, including $2,096 million of non-current deferred lease revenue |
| Quarter revenue | $3,661 million | $228 million, of which $200 million is AI cloud |
| Near-term clock | 36% of RPO in the 24 months to 30 Sep 2028, about $47.6 billion | $1,529 million of RPO within 12 months; $1,652 million in the next 12 |

When does the book become revenue?
Revenue starts when the company delivers and the service is available. Until that day both prints are a clock.
CoreWeave expected to recognise 36% of its $132.3 billion RPO over the 24 months to 30 September 2028, 38% in months 25 to 48, and the rest in months 49 to 86. Our arithmetic: about $47.6 billion, about $50.3 billion, and about $34.4 billion. Month 86 is seven years and two months from the balance-sheet date.
On 30 June 2026 unsatisfied RPO was $103.7 billion, with 41% expected over the 24 months to 30 June 2028, about $42.5 billion by our arithmetic. By September the near-term share had moved from 41% to 36%, and the dollars in that window had moved from about $42.5 billion to about $47.6 billion. The far end of the disclosure moved from month 78 to month 86.
RPO rose by $28.6 billion in the quarter, by our arithmetic, against $3,661 million of revenue recognised. The filing does not split that rise into new contracts, revenue recognised, and cancellations.
Who gets paid — and where is the stuck step?
Our read: the build and the lenders are paid while the book is still a book. The neocloud recognises revenue when the cluster is delivered and available.
- Equipment and buildings. Cash spent on property and equipment, including capitalised software, was $23,558 million in the nine months to 30 September 2026. Revenue in those nine months was $8,314 million. The cash out was 2.83 times revenue recognised, by our arithmetic. The filing does not name the suppliers.
- Lenders. Interest expense, net, was $846 million in the quarter. Operating income was $207 million.
- Customers who pay early. Deferred revenue of $10.0 billion is cash already in for work still owed. The 10 November release said CoreWeave expects about $9 billion of further prepayments and deposits in the next three months. That is an expectation, not cash already booked.
- The neocloud. In the quarter, 98% of revenue came from committed contracts, recognised as the capacity is delivered.
The stuck step is delivery. Both definitions hold the dollars until delivery and availability. Our GPU cluster acceptance Explained is the test at the end of that wait. Our contracted power Explained is the megawatt version of a signed claim that is not yet earning. The same release put active power over 1.7 gigawatts, after more than 200 megawatts added, with more than 1.85 gigawatts still expected at year-end.
What would change the view?
- The prints part. If the “other amounts” in backlog move well past RPO, the press-release book and the accounting remainder are no longer one story. On 30 September 2026 they were $0.2 billion apart on the rounded prints.
- More contracts become cancellable. CoreWeave already moved $1.9 billion out of deferred revenue for that reason. Whether RPO moves with a larger reclassification is something the next filing would have to say.
- The lease book grows. Leases were about $0.3 billion, and lease income was not material. If that book became a large share of backlog, as IREN’s $13,957 million of leases already is, the two prints would separate.
- The near-term dollars stall. Dollars expected in the next 24 months rose from about $42.5 billion to about $47.6 billion while their share of the book fell. A flat dollar slice beside a rising headline would mean new signatures are landing further out.
Common misconceptions
- People assume revenue backlog and RPO are different piles of money. Actually, at CoreWeave on 30 September 2026 they were two prints of one book, about $132.5 billion and $132.3 billion.
- People assume deferred revenue is the gap between the prints. Actually it was $10.0 billion and sits inside RPO. The printed gap was about $0.2 billion, by our arithmetic on the rounded figures.
- People assume every neocloud’s backlog equals its RPO. Actually IREN’s backlog was $20.3 billion and its ASC 606 RPO was $6,347 million. The lease book sits outside RPO.
- People assume a bigger backlog is this year’s revenue. Actually 36% of CoreWeave’s RPO, about $47.6 billion, is the 24-month slice to 30 September 2028. The disclosure runs to month 86.
FAQ
What is the difference between revenue backlog and remaining performance obligation?
Revenue backlog is a company’s own total of future revenue under committed contracts. Remaining performance obligation, or RPO, is the accounting remainder: the transaction price allocated to work not yet delivered. The company writes the backlog definition. The accounting rules set RPO.
Is revenue backlog the same as RPO?
Only when the company’s wrapper matches the accounting cut. At CoreWeave on 30 September 2026 the prints were about $0.2 billion apart, about $132.5 billion of backlog and $132.3 billion of RPO, by our arithmetic on the rounded figures. At IREN, backlog was $20.3 billion and ASC 606 RPO was $6,347 million, because the lease book sits outside RPO.
Where does deferred revenue sit against RPO?
Inside it. Deferred revenue is cash or a bill already on the balance sheet for work not yet delivered. CoreWeave’s deferred revenue was $10.0 billion on 30 September 2026, and its 10-Q says RPO includes billed and unbilled amounts. The $0.2 billion between backlog and RPO is a separate estimate.
How much of CoreWeave’s RPO is expected in the next two years?
CoreWeave expected 36% of its $132.3 billion RPO to be recognised over the 24 months ending 30 September 2028. That is about $47.6 billion, by our arithmetic. A further 38%, about $50.3 billion, sits in months 25 to 48, and the rest runs to month 86.
Why is IREN’s backlog larger than its RPO?
IREN’s backlog includes lease arrangements, and leases are not remaining performance obligations under ASC 606. The lease book was about $13,957 million against $6,347 million of ASC 606 RPO, and those two lines add to the $20.3 billion backlog.
When does revenue backlog become revenue?
When the company delivers the capacity and the service is available. CoreWeave and IREN both say the backlog waits on delivery and availability. The signature starts the clock. Revenue is the delivery.

How we check this
Figures come from the company filings and releases named below, each dated. The $9 billion of prepayments is the company’s expectation in its 10 November 2026 release, not cash already received. Where a filing is silent, including on what CoreWeave’s “other amounts” contain and on whether the $1.9 billion reclassification left RPO, the page says so. Sums, shares and differences are our arithmetic, with the inputs shown above. Who gets paid, and the stuck step, are our read.
