The IBIT issuer is marketing high-grade notes for a 1-gigawatt Meta AI campus in El Paso. Orders came in lukewarm — and the same debt wave includes Hut 8's $4.25B raise. The gigawatt economy that bitcoin mining built now has a much bigger tenant.
One gigawatt in El Paso: enough power for 750,000 homes, one AI tenant — or a very large bitcoin mine.
The company that runs the largest spot bitcoin ETF spent this week selling a very different product. BlackRock began marketing $12.3 billion of high-grade bonds to fund a Meta data center campus in El Paso, Texas — a single 1-gigawatt AI facility, financed by one of the largest corporate-style debt deals of the year. The notes, due 2048, are issued through a holding company called Sopaipilla Investor and were shopped at roughly 2.875 percentage points over Treasuries, with JPMorgan and Morgan Stanley running the books.
Why should a bitcoin reader care about Meta's server bill? Because the deal sits at the intersection of three things this site tracks obsessively: BlackRock, the debt market that funds bitcoin miners, and the fight for cheap electricity. Start with the structure. The bonds don't touch BlackRock's balance sheet — they're backed by the project itself, in which BlackRock subsidiaries Global Infrastructure Management and HPS Investment Partners hold 80% and Meta holds 20%. Meta gets a gigawatt of AI compute by 2028; BlackRock gets decades of fees; bondholders get a single-tenant credit dressed in investment-grade clothing. It's the same off-balance-sheet template Meta used in Louisiana, and it's exactly the kind of
private-credit engineering that has quietly become the funding model for the whole AI buildout.
The market's response was the story. Orders reached about $17 billion against $12.3 billion on offer — covered, but lukewarm by the standards of a trade that was drawing frenzied demand a quarter ago, and one participant put it plainly: the market is not handing out easy money for AI projects anymore. The fatigue has a supply-side explanation. Data-center debt has flooded in — more than $20 billion of high-yield bonds and loans launched in one recent three-week stretch — and that wave includes bitcoin's own: Hut 8's $4.25 billion raise last month was part of the same queue. When allocators start rationing AI-infrastructure credit,
miners pivoting to AI hosting are borrowing from a suddenly pickier lender.
Then there's the power. One gigawatt is roughly 750,000 homes' worth of electricity — or, in the units this site usually uses, a campus that could host on the order of 30 EH/s of modern mining hardware. It will host none. Every gigawatt-scale campus that AI claims in Texas is a gigawatt bitcoin miners don't get at yesterday's prices, and the squeeze is already visible in the tape:
hashrate has plateaued for the first time in six years, partly because AI tenants outbid miners for the same substations. Meta pays more per megawatt-hour than any hashprice can justify. That's the blunt economics behind every miner's "AI/HPC pivot" slide.
The BlackRock through-line deserves its own paragraph. The firm collects fees on IBIT — the bitcoin ETF whose flows
snapped a seven-day inflow streak on Friday — while simultaneously becoming the largest lender-operator in AI infrastructure, fresh off a $40 billion acquisition of Aligned Data Centers. To BlackRock, bitcoin exposure and AI compute are the same product line: hard-asset yield sold to institutions. Where the marginal institutional dollar goes — a spot bitcoin ETF or a 22-year data-center note at Treasuries-plus-2.875 — is now, literally, an allocation decision inside one firm's product catalog.
For bitcoin, the readable signal is credit appetite. When data-center paper prices easily, miners refinance cheap, AI pivots pencil, and the sector's balance sheets breathe. When a Meta-anchored, BlackRock-sponsored gigawatt deal has to work for its orders, everything below it on the credit ladder — including every miner's next raise — just got more expensive. Friday's ETF outflow and this week's bond book are two readings of the same thermometer: institutions still want hard-asset exposure, but the easy-money phase of this cycle is over.

WHY IT MATTERS
Bitcoin miners built the gigawatt playbook — find stranded power, build fast, monetize compute. AI hyperscalers copied it with deeper pockets, and now the debt market that funds both is showing fatigue. Credit appetite for gigawatt infrastructure sets the price of every miner's next raise, every AI pivot, and every kilowatt-hour both industries bid on. This bond book is the cleanest read yet on where that appetite stands.
What to watch next
1.Final pricing. If the deal prices wide of the 2.875-point talk, the AI-credit repricing is real — and miner refinancing costs follow.
2.Miner Q2 reports. Watch how much capacity public miners say they've converted to AI/HPC hosting — and at what contracted rates versus hashprice.
3.Texas grid math. ERCOT interconnection queues will show whether AI campuses are displacing planned mining load outright.
