IREN Climbs 4% as Co-CEO Says Debt and Prepayments Can Fund FY27 Capex, TeraWulf Slips

IREN's co-CEO just made a bold claim about how the company funds its massive fiscal 2027 buildout without a big equity raise, and the market is reacting while peers like TeraWulf head in the opposite direction.

Shares of IREN (NASDAQ:IREN) are rising Monday afternoon after co-founder and co-CEO Daniel Roberts said the AI cloud operator‘s fiscal 2027 capital plan doesn’t require a large equity raise. IREN stock is up 4% to $36.76 at midday, extending a run that had shares up 21% over the past month through Friday’s close.

This move is company-specific. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.5% to $765.91, so the broad market is slightly lower even as IREN stock rises. Peer TeraWulf (NASDAQ:WULF) stock is down 2% to $15.09, while fellow miner-turned-AI-host Cipher Mining (NASDAQ:CIFR) isn’t participating, underscoring that today’s catalyst is IREN-specific funding news rather than a sector-wide bid.

Roberts Post Addresses the Dilution Worry

In a post Monday, Roberts said IREN’s forecasted $25 billion to $30 billion of fiscal 2027 capital expenditures “isn’t an equity number.” He added, “Customer prepayments can cover about half the GPU capex. Lenders can fund most of the rest.” That speaks directly to investor anxiety that followed the fiscal 2026 fourth-quarter report, when the market questioned whether an at-the-market offering or more convertible notes would be needed to fund the plan.

Management said IREN entered fiscal 2027 with about $14 billion in cash, committed GPU financing and customer prepayments, and is targeting another $8 billion through GPU financing and prepayments. The rest is expected to come from data center financing, operating cash flow and corporate sources. Recent customer prepayments have covered 45% to 55% of associated GPU capital expenditures on new deals.

The financing stack has already scaled quickly. IREN arranged $3.6 billion of Microsoft-related GPU financing at a weighted average interest rate of 6%, and secured $2.8 billion for other deployments, including $2.4 billion at a 9% fixed rate for the Mackenzie expansion, while raising approximately $19 billion, with about $3 billion of that from equity over the past 12 months. Its entire data center portfolio remains unencumbered, including the four Horizon deployments at Childress, and no data center financing transaction has closed yet.

Roberts framed the mechanism as a “funding flywheel.” When customer prepayments cover roughly half of GPU cost and lenders finance 90% of the balance, the arithmetic can leave IREN with more cash than the compute itself required, freeing capital to seed the surrounding data center shell. GPU financing, once a private-credit product with mid-teens returns, now includes investment-grade paper in the 6% area.

Bear Case Still Sits in the Numbers

The financials matter here. IREN’s net loss widened 176% sequentially to $684 million in the fiscal 2026 fourth quarter, with $450.4 million of impairments accounting for most of the shortfall. Mining revenue dropped 40% to $66.7 million as older rigs came out ahead of GPU installations.

Adjusted EBITDA also fell hard sequentially. IREN posted $19.2 million in adjusted EBITDA in the June quarter, versus $59.5 million the prior quarter, as costs across sales, R&D and site operations ran ahead of the AI Cloud ramp. Cash SG&A is guided up another $40 to $50 million sequentially in the September quarter.

The offset sits on the AI side. AI Cloud Services revenue reached $70.5 million in the June quarter, up from $33.6 million in March. The company has $4 billion in contracted annual recurring revenue tied to capacity expected online by year-end, which is what makes the funding math workable in the first place.

Microsoft (NASDAQ:MSFT | MSFT Price Prediction) is the anchor Horizon customer behind that ARR figure. The first 50-megawatt Horizon deployment was delivered in August, and Horizons 2 through 4 are targeted for the December quarter.

Peer Divergence Is the Signal

TeraWulf stock is falling while IREN stock rises, even though both names sit in the same Bitcoin (CRYPTO:BTC)-mining-to-AI-infrastructure trade (we profiled seven of the picks-and-shovels names powering the AI buildout, from power to cooling, in a free report you can grab here).

Cipher Mining is quiet on the session. Today’s move separates the group by funding certainty and near-term delivery timeline rather than repricing everyone together.

What to Watch

The near-term catalyst is any data center financing announcement. Roberts has described that layer as the “next frontier,” and IREN has confirmed no transaction has closed yet. A first close on an asset-backed deal against the unencumbered Horizon portfolio would validate the funding model Roberts sketched out Monday.

Investors should size their IREN share positions carefully given the execution stakes. The fiscal 2027 plan is large, delivery timelines are compressed, and hardware impairments are still weighing on the GAAP line. A gain on a single executive post is a sentiment shift, and the balance sheet claim underneath it can be tested only quarter by quarter.
