Bitcoin Miners With AI Plans Fall 10% to 12% as CPI Hits 3.7% and Gartner Warns on Neoclouds

Bitcoin mining stocks with big AI ambitions took a beating on Wednesday, Oct. 14, and the coin they mine barely flinched by comparison.

The CoinShares Bitcoin Mining and Digital Power ETF (WGMI) fell 10.7%. Bitcoin dropped roughly 2% and slid below $82,000. IREN fell 12.2% to $30.56 at the 4 p.m. ET close. Cipher Digital lost about 12%. Hut 8 fell 10.5% to $74.87. CoreWeave, the Nvidia-backed AI cloud provider, plunged 15.5%.

Three events, one day

The Labor Department's September inflation report landed at 8:30 a.m. ET. Consumer prices rose 3.7% over the past 12 months, up from 3.4% in August. Treasury yields jumped and bets on further Federal Reserve rate hikes grew.

Stocks broadly sold off. The S&P 500 fell 1.11% and the Nasdaq Composite fell 1.88%, each its worst day since July. A semiconductor index dropped 4.3%. Dell fell 11.3%, Oracle 8.8% and Marvell 8.7%. Nvidia slid 3.2%.

Then came Gartner. The research firm forecast that more than 80% of specialized AI cloud providers, known as neoclouds, will stop operating independently by 2030. It also said AI infrastructure spending could carry more than $3.5 trillion in potential impairment by the end of 2030 if spending continues at its current pace.

Gartner's math: owners of AI data centers would need $8.5 trillion in cumulative revenue to cover announced project costs and financing while earning a 12% return on invested capital. Enterprise and consumer AI revenue tied to those data centers is projected at no more than $3.6 trillion.

"Enterprise and consumer AI revenue will be insufficient to support profitable returns," said Will Sommer, a Gartner senior director analyst. The forecast is industry-wide. It is not an estimate for IREN, Cipher or Hut 8.

No one has established which of these events moved which stocks. Steve Sosnick, chief strategist at Interactive Brokers, pointed to a chip sector with "so much good news priced into" it. CNN also reported that higher yields and sticky inflation have raised the cost of the data center buildout, which worries investors about the debt-heavy corners of the AI business.

The financing problem

Miners have what AI customers want: land already wired into the power grid. Companies including IREN, Cipher, Hut 8 and Core Scientific have each pursued plans to convert or expand sites for AI.

The conversion is expensive. Cointribune put a classic mining site at $700,000 to $1 million per megawatt. An AI facility with liquid cooling runs $8 million to $15 million per megawatt.

A June analysis from BlocksBridge Consulting, citing VanEck data, estimated that publicly traded miners need roughly $50 billion to finish their planned AI projects. IREN alone faces a $21.1 billion gap. Riot Platforms is at $7.2 billion and HIVE Digital at $4.6 billion.

Lenders are also picking and choosing. BlocksBridge said in its Miner Weekly newsletter that "big lenders have become more selective about data center loans and decisions increasingly depend on the customer, the contract and the path to completion."

IREN's own paper shows the spread. It secured $3.65 billion in GPU financing in June at a blended 6% rate. In August it arranged $2.4 billion at a fixed 9%. BlocksBridge notes the two deals cover different projects and are not directly comparable.

Cipher's deals carry other costs. Google agreed to backstop $1.4 billion in Cipher lease obligations in exchange for warrants representing 5.4% of Cipher's equity, subject to adjustments. Exercising the warrants could dilute existing shareholders.

On Wednesday Cipher priced $850 million in senior unsecured convertible notes with a 0.00% coupon, due Nov. 1, 2032. The company plans to use most of the net proceeds for its Barber Lake project, high-performance computing expansion and development sites.

The miners' case

The companies argue the pivot is the point. Long-term leases with large tech customers can produce steadier revenue than mining, which swings with the coin price, network difficulty and power costs.

Hut 8 announced a 15-year lease in July for 352 megawatts of IT capacity at its Beacon Point AI campus, with a stated base-term contract value of $9.8 billion. For the fiscal year ended June 30, IREN reported $128.8 million in AI Cloud Services revenue against $578.2 million from Bitcoin mining.

So mining still pays most of the bills at IREN, while the AI build-out is financed largely with outside money.

The broader backdrop is not kind to the old business either. VanEck data showed miner debt up roughly 500% from the second quarter of 2024 to the peak of last October's Bitcoin bull market. Capital needs have kept growing during the current Bitcoin bear market, according to BlocksBridge.

What comes next

Cipher's convertible notes are expected to settle Friday, Oct. 16, subject to closing conditions. The next test is what these companies pay to borrow after a 3.7% inflation print, and whether lenders keep funding projects at the 6% rate IREN landed in June or the 9% it accepted in August.
