$117.5bn of disclosed HPC and AI contract value, announced by 12 of the 18 miners in the 18 months to 2026-09-06.

KEEL: no HPC or AI colocation, lease or hosting contract signed, as of 2026-08-10.

Active negotiations at three sites with deepening commercial engagement

Keel (formerly Bitfarms) has decommissioned all US bitcoin mining for HPC construction and reports a 2.2 GW pipeline, but the Q2 2026 release describes prospective tenants negotiating, not a signed lease. Adjacent agreements that are not customer deals: a $128.7 million binding purchase commitment for critical IT equipment and building materials for 18 MW gross (November 2025), a $300 million Macquarie credit facility for Panther Creek HPC development (April 2025), a 21 MW third-party ASIC hosting contract at Panther Creek, a partnership with builder T5 Data Centers to advance HPC/AI development at Panther Creek (August 2025), and a Hydro-Sherbrooke agreement for the conditional transfer of 96 MW (August 2026).

ARBK: no HPC or AI colocation, lease or hosting contract signed, as of 2026-04-30.

These hosting agreements ended in March and April of 2026, respectively.

Argo Blockchain files as a foreign private issuer (20-F). Its only hosting agreements in the window are bitcoin ASIC hosting with Merkle Standard (9,315 miners at Memphis, up to 4,000 in Washington State), which ended in March and April 2026. HPC and AI appear in the 20-F only as competition for power. No 2026 interim 6-K with an HPC contract was found in the corpus checked.

VIP: no HPC or AI colocation, lease or hosting contract signed, as of 2026-08-17.

We control 104 MW of existing energized capacity and have a 654 MW development pipeline across owned sites, including more than 100 MW of near-term AI/HPC opportunities that we are actively working to commercialize.

Vulcan Infrastructure and Power (formerly Greenidge Generation) has a pipeline, not a contract. Watch out for the CoreWeave lease in its August 2026 investor presentation: the 100 MW Lancaster lease to CoreWeave and the 19-year 178 MW triple-net lease are case studies of what its new strategic investors (Machine Investment Group and Atlas) did before investing in Vulcan, not Vulcan contracts. Also in the window: a proposed NYSEG interconnection agreement for 60 MW of non-curtailable power at Dresden (May 2026).

Under the terms of the agreement, Endeavor will purchase and deliver approximately 25,000 mining computers, and Big Digital will provide Endeavor with approximately 75MW of compute capacity.

Big Digital Energy (formerly Mawson Infrastructure) signs colocation agreements, but they are bitcoin ASIC colocation: 9 MW, 20 MW and 64 MW enterprise agreements (September 2025), a related-party 75 MW agreement with the Endeavor Group (April 2026) and a roughly 50 MW framework with Consensus/NYDIG (June 2026). Its AI work in the window is a GPU pilot on a decentralised AI network (October 2025) and an AI colocation plan for the Texas Load House site (July 2026), neither of which is a signed AI customer contract.
