Under the lease deal, Cipher will provide turnkey data centre space and power for AWS’ artificial intelligence (AI) workloads in two phases, beginning in July and August 2026.

Earnings Boost Fuels Investor Confidence

Cipher also reported a sharp improvement in its third-quarter financials, narrowing its net loss to $3 million, compared to $46 million in the previous quarter. Adjusted earnings climbed to $41 million from $30 million, reflecting stronger operational efficiency and diversified revenue streams.

Following the announcement, Cipher’s stock jumped from $18.65 to a peak of $25.02, before settling at $22.76 by market close.

Cipher’s latest deal follows its September collaboration with Google, when the tech giant acquired a 5.4% stake in the miner through a $3 billion partnership involving data center firm Fluidstack.

“We’ve solidified our position in the high-performance computing space through our partnership with Google and Fluidstack,”

said Cipher CEO Tyler Page, adding that the Amazon deal marks “another major milestone” for the company.

Additionally, Cipher announced it now holds a 95% majority stake in a joint venture to develop a one-gigawatt AI hosting site in West Texas, named Colchis — a move designed to strengthen its presence in the growing AI infrastructure market.

Tech giants bet on Bitcoin Miners

Cipher’s announcement came as tech corporations increasingly partnered with crypto miners to expand computing infrastructure. IREN recently inked a $9.7 billion GPU cloud deal with Microsoft. TeraWulf secured a $3.7 billion hosting agreement in August with Fluidstack, backed by Alphabet, Google’s parent company.
