Big Tech confirmed $650B in AI infrastructure spend. Bitcoin miners are watching.
Microsoft, Meta, Amazon, and Alphabet put their AI budgets on paper yesterday. The question for IREN, TeraWulf, and Cipher Digital is whether a $650B demand signal translates into signed contracts.

- →Microsoft, Meta, Amazon, and Alphabet reported quarterly earnings on April 29, collectively pointing to roughly $650 billion in AI infrastructure spend this year, per CoinDesk.
- →Bitcoin miners IREN, TeraWulf, and Cipher Digital have been pivoting toward AI and high-performance-computing hosting deals, and the earnings confirm that the hyperscaler demand side of that bet is real.
- →Nvidia reports on May 20, which CoinDesk identifies as the next major sentiment test for AI infrastructure equities and the bitcoin miners tied to the HPC hosting trade.
- HPC → High-performance computing: densely packed servers and fast networking used for AI model training and other compute-intensive workloads.
- hyperscaler → A company that runs massive global cloud infrastructure at scale, like Amazon Web Services or Microsoft Azure, and continuously expands capacity to meet demand.
Microsoft, Meta, Amazon, and Alphabet reported quarterly earnings on April 29, with combined AI infrastructure spend for 2026 tracking toward roughly $650 billion, per CoinDesk.
The individual prints back it up. Microsoft's AI business hit a $37 billion annual revenue run rate, up 123% year-over-year, per its fiscal Q3 2026 release. AWS sales came in at $37.6 billion for Q1 2026, up 28%, per Amazon's filing. Meta put $19.84 billion in capital expenditures to work last quarter and guided full-year capex to $125 billion to $145 billion, per Meta's release.
The crypto relevance is indirect but specific. Bitcoin miners including IREN, TeraWulf, and Cipher Digital have been repositioning toward AI and high-performance-computing hosting deals, competing for hyperscaler overflow demand. The earnings confirm the demand side is real. The contract pipeline is the open question.
After-hours moves did not validate the pivot trade. Microsoft fell about 2.4%, Meta fell 6.6%, Amazon fell 3.7% on the session, per CoinDesk. IREN dropped 0.3%, TeraWulf and Cipher Digital each fell 0.5%. Bitcoin was down about 0.9% on the day.
Nvidia reports May 20. That print is the actual stress test for the AI infrastructure trade.
Cipher Digital, IREN, and TeraWulf are now competing for AI hosting contracts against every data center operator who read the same $650 billion earnings releases: the window for being the early mover was before April 29, not after.
Watch for any of IREN, TeraWulf, or Cipher Digital disclosing a signed AI or HPC hosting contract before Nvidia reports on May 20: that announcement would confirm the pivot has moved from positioning to revenue.
