Cipher Mining strikes $5.5B AWS partnership
Bitcoin mining firm Cipher Mining saw its shares surge by more than 34% on Monday after announcing a long-term 15-year partnership with Amazon Web Services (AWS) valued at $5.5 billion. The agreement marks one of the largest collaborations yet between a crypto miner and a global technology powerhouse.

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.

The AI boom may follow the path of the 19th-century railway bubble, and builders may not be the ultimate winners
Goldman Sachs analyst Bobby Molavi compared the current situation to the 19th-century British railway mania: 500 companies spent more than the nation's annual income building 8,000 miles of railway, with most early investors losing out, while the real beneficiaries were the later "passengers." He pointed out that the current AI craze is driven by both debt and momentum, and that the S&P 500’s forward P/E ratio of 18x is only "a bit cheaper." Whether the builders can retain value is uncertain, and history does not offer an optimistic answer.

Multiple venture capital firms have advised their portfolio companies to lower valuation expectations and to quickly build up cash reserves. Market participants warn that the outcome of Anthropic’s IPO will be a barometer for the industry: if successful, the boom will continue; if it fails, some companies may face elimination.
