IREN Has $4 Billion in Contracted AI Revenue. Who Is Paying for the Buildout?
IREN has been putting out some very large numbers.
One of the biggest is $4 billion.
That is the annual recurring revenue already contracted against the AI Cloud capacity IREN expects to have in place by the end of 2026. About $1 billion of ARR is already operating.
The rest depends on more GPUs and data center capacity coming online.
Building all of that requires an extraordinary amount of capital.
IREN expects to spend roughly $25 billion to $30 billion in fiscal 2027.
The company does not have $30 billion sitting in a bank account, nor does it intend to fund the expansion entirely with its own cash.
So where does the money come from?
Start With the Customer
Microsoft is one of IREN's largest customers.
The two companies signed a five-year AI Cloud agreement worth approximately $9.7 billion. IREN will provide Microsoft with access to NVIDIA GB300 GPUs deployed across its data center infrastructure.
Microsoft also agreed to prepay 20% of the contract value.
That works out to roughly $1.9 billion.
This matters because IREN has to spend heavily before it can deliver the computing capacity Microsoft is buying.
A long-term customer is doing more than promising future revenue. The upfront payment helps fund the infrastructure needed to provide the service.
But it still doesn't cover the full cost.
Then Come the Lenders
The GPUs and related equipment for the Microsoft deployment carry a purchase price of approximately $5.8 billion.
IREN is not paying all of that in cash.
It secured about $3.65 billion in GPU financing, with a blended cost of debt of approximately 6%.
Combined with Microsoft's prepayment, IREN says roughly 96% of the GPU capital expenditure associated with the Microsoft contract is funded.
The structure is fairly simple:
Microsoft signs a long-term contract and provides a prepayment.
↓
IREN secures additional financing.
↓
IREN buys GPUs and builds the required infrastructure.
↓
Microsoft uses the computing capacity.
↓
IREN collects revenue over the life of the contract.
This is an important part of the IREN story.
The company is using customer commitments and outside capital to build infrastructure far larger than it could fund with cash alone.
Microsoft Isn't the Only Example
IREN has also secured approximately $2.8 billion of financing for GPU deployments serving other customers.
About $2.4 billion of that financing, involving Blue Owl and PIMCO among others, carries a 9% fixed rate and funds roughly 90% of the associated GPU capital expenditure.
Management has also said that customer prepayments on some recent contracts have covered roughly 45% to 55% of GPU capex.
That changes the economics of expansion.
IREN does not necessarily have to spend a dollar of its own capital for every dollar of infrastructure it builds.
In some cases, customers provide part of the money upfront and lenders provide much of the rest.
That can make rapid expansion possible.
It also introduces debt and financing costs that shareholders need to track.
Has IREN Already Funded the Entire $30 Billion?
No.
IREN's fiscal 2027 capital expenditure guidance is approximately $25 billion to $30 billion.
Management says the company currently has about $14 billion available from cash, committed GPU financing and customer prepayments.
IREN expects another roughly $8 billion of GPU-related financing and customer prepayments.
There is an important distinction between those two numbers.
The $14 billion represents funding the company says is already secured or available.
The additional $8 billion is funding it expects to arrange.
For the remainder, management has discussed several possible sources, including financing against data center assets, operating cash flow and other corporate funding.
So it would be incorrect to say that the entire $30 billion buildout is already funded.
Don't Compare $4 Billion Directly With $30 Billion
At first glance, the numbers invite an obvious question:
Why spend as much as $30 billion to generate $4 billion a year?
But that comparison is misleading.
The $25 billion to $30 billion fiscal 2027 capex plan is not simply the cost of producing the $4 billion of contracted 2026 ARR.
It also includes infrastructure for additional capacity expected to come online in 2027 and beyond.
At the same time, some GPU spending for new liquid-cooled capacity expected later in 2027 falls outside that fiscal 2027 capital plan.
The two numbers cover different things and different periods.
What they do show clearly is how IREN is changing.
It is becoming an increasingly capital-intensive AI infrastructure business.
Shareholders Are Another Source of Capital
Borrowing isn't the only way IREN can raise money.
It can also sell shares.
IREN established a new at-the-market equity program allowing it to sell up to $6 billion of ordinary shares.
That does not mean the company will necessarily sell the full $6 billion.
But IREN has already been using equity as a source of capital.
For shareholders, this matters because issuing new shares can create dilution.
Imagine a company as a pizza divided into ten pieces.
If more shares are issued, each existing piece represents a smaller percentage of the company unless the money raised makes the overall company sufficiently more valuable.
That is why revenue growth alone doesn't tell shareholders everything they need to know.
The number of shares matters too.
NVIDIA Has an Unusual Role
NVIDIA's relationship with IREN is particularly interesting.
In May 2026, IREN announced a $3.4 billion, five-year AI Cloud agreement with NVIDIA, alongside a broader strategic collaboration supporting IREN's data center expansion.
NVIDIA also received the right, subject to certain conditions, to purchase as many as 30 million IREN shares at $70 per share.
If fully exercised, that would represent as much as $2.1 billion.
It is important to be precise here.
NVIDIA has not simply purchased 30 million IREN shares. These are rights that become available subject to specified conditions.
The arrangement gives NVIDIA several connections to IREN at once: it is an AI Cloud customer, a central supplier within the GPU ecosystem, and potentially a significant shareholder.
IREN Still Has Another Financing Option
Management has also pointed to IREN's data center assets.
Those assets are currently largely unencumbered, meaning they have not already been pledged against major project-level borrowing.
That leaves IREN with another potential source of capital.
If necessary, the company could potentially raise financing against some of those assets.
That provides financial flexibility, but it could also add another layer of debt or financing obligations.
The relevant question is not simply whether IREN can borrow more.
It is what the company can earn with the capital it raises.
Look Beyond the $4 Billion Headline
IREN's $4 billion of contracted ARR is significant, and about $1 billion is already operating.
The first 50MW Microsoft deployment at Horizon 1 has also now been delivered.
So this is no longer entirely a story about capacity that may exist years from now.
But the scale of the expansion requires looking at more than revenue.
IREN currently has several large numbers moving at the same time:
$4 billion in contracted ARR for 2026 capacity.
$1 billion of operating ARR.
$25 billion to $30 billion of planned fiscal 2027 capital expenditure.
About $14 billion of currently secured or available funding.
Roughly $8 billion of additional GPU financing and customer prepayments the company expects to arrange.
$3.65 billion of Microsoft-related GPU financing at a blended cost of about 6%.
And another $2.8 billion of financing for other GPU deployments.
None of these numbers, by itself, tells shareholders whether IREN's expansion will ultimately create value.
They need to be read together.
The Question That Matters Per Share
GPU count matters.
Megawatts matter.
Microsoft matters.
Revenue growth certainly matters.
But as IREN becomes larger, shareholders have a few other numbers to watch.
How much capital does the company need to generate its AI revenue?
How much of that capital comes from customers?
How much is borrowed?
What does that debt cost?
How many new shares are issued along the way?
Ultimately, those questions lead to a simpler one:
As IREN grows, does the value represented by each share grow with it?
IREN is becoming difficult to describe as simply a Bitcoin miner that moved into AI.
It is increasingly building AI infrastructure through a combination of long-term customer contracts, prepayments, debt, equity and enormous amounts of computing hardware.
If the model works, those financing tools could allow IREN to build far more infrastructure than it could finance from its own balance sheet alone.
The trade-off is that faster growth requires more capital.
For shareholders, that makes one number particularly useful to follow:
How much capital does IREN need to create each dollar of durable AI revenue?
And once that capital has been raised and spent, how much of the resulting value belongs to each share?
BEYOND THE OBVIOUS.
