Anthropic has signed a 20-year lease with bitcoin miner TeraWulf for data center space at the company’s Justified Data Campus, marking one of the longest infrastructure commitments between an AI firm and a crypto mining operator.
TeraWulf announced the lease agreement alongside a separate transaction involving the sale of a majority interest in its Abernathy joint venture to FluidStack. The lease places Anthropic as a long-term tenant at TeraWulf’s Kentucky-based facility. For related coverage, see Truth Social Withdraws Bitcoin ETF Application From SEC.
The deal is valued at approximately $1.9 billion over its 20-year term, according to Data Center Dynamics. That figure underscores the scale of capital AI companies are now directing toward physical infrastructure operated by firms with roots in bitcoin mining.

Why a Bitcoin Miner Is Leasing to an AI Company
TeraWulf built its reputation as a bitcoin mining company, operating facilities designed for the intense power and cooling demands of cryptocurrency mining hardware. Those same physical characteristics, high-density power delivery, large-scale cooling systems, and remote locations with energy access, are precisely what AI model training and inference workloads require.

For Anthropic, the lease secures dedicated compute infrastructure over a two-decade horizon. That duration is unusual in the data center industry, where leases of five to ten years are more common. A 20-year commitment signals that Anthropic expects its infrastructure needs to remain substantial and geographically stable for the foreseeable future.
For TeraWulf, the deal represents a pivot familiar to several publicly traded mining companies. Hut 8 similarly reshaped its strategy around a $7 billion AI lease, reflecting a broader pattern where bitcoin miners are monetizing their power and facility assets by hosting AI tenants willing to sign long-term contracts.
What a Two-Decade Commitment Signals
A 20-year lease is a bet on infrastructure durability. It implies that both parties expect the underlying facility, its power supply, and the local regulatory environment to remain viable through the mid-2040s. For the crypto mining sector, such agreements provide revenue certainty that bitcoin mining alone, with its halving cycles and price volatility, cannot guarantee.
The deal also positions Anthropic, which has faced scrutiny over its U.S. government relationships, as a company willing to make massive domestic infrastructure investments. The Kentucky location aligns with a trend of data center development in states offering competitive energy costs and favorable permitting environments.
With rival OpenAI also expanding its infrastructure footprint, the race for AI compute capacity is increasingly intersecting with the assets bitcoin miners spent years building. TeraWulf’s $1.9 billion lease with Anthropic may be among the largest such deals to date, but it is unlikely to be the last as AI demand continues to outpace available data center supply.
