Another segment of Bitcoin's global mining capacity came offline this week. Hyperscale Data (NYSE American: GPUS) switched off its Bitcoin miners at its Dowagiac, Michigan, facility on September 1 and is converting the site to an AI co-location cash contract worth over $1.2 billion, according to the company's statement on September 2.

The shutdown matters for the mining sector because it does not occur in isolation: another powered, licensed facility is withdrawing from Bitcoin mining as it prepares to serve AI clients. Facilities like Dowagiac — already built out with grid interconnections, transformers, and permits — are difficult and slow to replicate, which is precisely what makes them attractive to AI tenants facing a shortage of immediately available power.

What Hyperscale Signed

According to the company's news release and 8-K filing dated June 24, the deal was struck between Alliance Cloud Services, a fully owned subsidiary of Hyperscale, and an unnamed California-based neocloud provider. The contract, set out in a master services agreement signed on June 23, covers 20 megawatts of AI computing capacity.

The contract has an initial term of ten years, with two options to extend by five years each. It could generate up to $1.2 billion in revenue. The client also holds a right of first offer on an additional 32 MW of capacity; if that power is acquired within the first two years and used across the extensions, expected revenues could reach $3 billion. The client paid a $5 million upfront charge and a $5.6 million security deposit.

"The immediate shutdown of the Bitcoin mining operations allows our team to focus the Facility's power, infrastructure and resources in preparing the Facility for its usage by our Customer."

— William Horne, CEO, Hyperscale Data

Hyperscale intends to profit from selling its mining servers and believes the Michigan facility can eventually deliver an estimated 340 MW of power.

Why a Working Mine Gets Switched Off

The shift is driven by economics. A prior Cryptopolitan report revealed that Hyperscale sold nearly 150.5 BTC for roughly $9.6 million. CoinShares data cited in that report put the average cash cost of producing one Bitcoin in the fourth quarter of 2025 at around $79,995 — well above BTC prices of $68,000 to $70,000 at the time.

With mining margins squeezed and AI clients offering firm contracts, a powered site may be worth more running GPUs than ASICs. Horne has said Hyperscale's value should rise as it secures more contracted power, an approach broadly consistent with VanEck's framework for valuing miners as AI infrastructure.

Capacity Draining Out of Mining

Hyperscale's agreement is small compared with the deals reshaping the industry. IREN has $9.7 billion in deals with Microsoft, TeraWulf signed an agreement worth approximately $19 billion with Anthropic, and Core Scientific has reported more than $14 billion in expected contract revenue. Hashrate Index reports that listed miners have announced more than $70 billion in combined AI and HPC contracts.

The transition comes as the Bitcoin network weakens. Average monthly hashrate has fallen from approximately 1,066 EH/s in Q1 to 1,004 EH/s in Q2 and 940 EH/s in Q3 2026 — a 6.3% quarterly decline and roughly 12% below the peak recorded in December 2025, according to Hashrate Index.

"This is a structural shift, not just just a cyclical low. Miners everywhere are being revalued as energy and AI infrastructure."

— Ethan Vera, COO of Luxor, via Hashrate Index

Hashrate Index attributes the decline primarily to weak mining profitability, with AI and HPC adding a longer-term structural pull. A falling hashrate mechanically eases network difficulty over time, which improves margins for the miners that remain — a dynamic that has historically accompanied capacity shakeouts. Galaxy Research notes that the miners best positioned for AI are those with large facilities and access to cooling water, dark fiber, consistent power, and the required permits. Hyperscale plans to continue mining at its Montana facility.

What to Watch Next

Hyperscale has not published a new AI launch date for Michigan. The company's June Form 8-K indicated Phase 1 was expected to be operational by September 21, while the accompanying press release suggested material revenues could begin at the end of September. Whether the client exercises its right of first offer on the additional 32 MW — and how quickly the remaining capacity is contracted — will shape the site's contribution to Hyperscale's revenue.

The broader takeaway is the trend itself: deteriorating mining economics are pushing high-cost operations offline at the same time AI is offering a more attractive use for those power facilities.
