Big Tech’s earnings week closed with a split screen. Amazon delivered one of its best quarters in years — $200.6 billion in revenue (+19.6%), AWS up 37% (its fastest growth in 18 quarters), EPS of $5.75 — and the stock surged from a $235.50 close to about $257 after hours, a gain north of 9%, per CNBC and TradingKey. Apple beat on both lines — EPS of $2.02 versus $1.88 expected on $109.4 billion of revenue, with iPhone sales up 22% — and still fell more than 6% in extended trading on weak, “supply constraints”-flagged guidance. For Bitcoin miners, though, the number that matters most came from Andy Jassy’s mouth: Amazon now expects roughly $220 billion of capital spending this year. The AI infrastructure race did not cool this week. It re-accelerated — and it is aimed straight at the same power, land, and grid interconnects the mining industry sits on.

The four-hyperscaler capex tally

This completes the picture we have tracked all week (see Wednesday’s Microsoft/Meta update). Microsoft beat with steady capex guidance and a $678 billion backlog — the calming datapoint. Meta raised its capex floor to $130–145 billion and crushed its own free cash flow — the alarming one. Amazon just outbid everyone with a ~$220 billion figure and, crucially, proved the revenue: 37% AWS growth against 31% expectations, with 39% AWS margins per Yahoo Finance coverage. Apple, the outlier, spends comparatively little on AI datacenters — its 6% slide is a hardware-cycle story, not an infrastructure one. Net message for the power market: the three biggest datacenter builders on Earth just committed to spending more, with Wall Street rewarding the one that spent the most.

Why miners care: the bid under their assets keeps rising

Bitcoin miners own what hyperscalers now need most: energized sites with grid interconnects, transformers, and cooling — assets that take years to permit and build from scratch. That is why the AI-pivot trade has dominated miner equities all year even as mining economics tightened (July’s difficulty retarget cut just 0.74%, the smallest of 2026, despite hashprice pressure). The verified benchmark deal remains IREN’s $2.8 billion agreement with Microsoft and Nvidia reported in late July — a number we cite carefully after last week’s wider “$9.7B” claims failed verification. Amazon’s $220 billion guide and AWS’s 37% growth strengthen the same thesis: every incremental AI dollar makes an energized megawatt more valuable, whether it hashes SHA-256 or trains models. The bear case — that a capex pullback would strand the pivot — took real damage this week: of the four reporters, only Meta’s spending drew punishment, and even Meta raised its floor.

The other side of the ledger

Two cautions before miners get carried away. First, hyperscaler capex flows overwhelmingly to chips and self-built campuses; only a slice reaches third-party site deals, and only the miners with large, energized, expandable footprints (the IREN/Core Scientific profile) are realistic counterparties — small-cap miners with hosting contracts and thin balance sheets get the narrative, not the checks. Second, the macro tape that pressures Bitcoin pressures miner treasuries too: with September hike odds near 81% and BTC around $65,000 — roughly half its all-time high — hashprice stays compressed, and miners holding BTC on balance sheet are marking losses just like Strategy, whose $8.22 billion Q2 we decode in today’s guide. The AI bid is a call option on miner real estate; it is not a hedge on the core business.

What to watch next

  • Miner Q2 reports land through August — watch for AI/HPC revenue segmentation, contracted-megawatt disclosures, and BTC-holdings marks under fair-value accounting.
  • ~August 11 difficulty retarget — tests July’s hashrate-floor thesis; a second small adjustment would confirm miners are staying online despite compressed margins.
  • Power headlines as the new catalyst — grid-interconnect and PPA announcements now move miner stocks more than hashprice does; Amazon’s $220 billion makes that asymmetry stronger.
  • Friday’s close — whether Amazon’s pop holds through the session tells you if the AI trade’s leadership is rotating from chips to infrastructure owners.

As of publication on July 31, 2026, Bitcoin trades near $65,000, Amazon leads Nasdaq futures higher, and the week’s scoreboard reads: AI infrastructure demand up, Bitcoin’s macro headwinds unchanged — and the miners still standing in the middle, holding the land everyone suddenly wants.

FAQ

Why do Amazon’s earnings matter for Bitcoin miners?

Amazon guided to roughly $220 billion of 2026 capital spending on AI and cloud infrastructure. That demand competes for the same power capacity, grid connections, and datacenter-ready sites that Bitcoin miners own, supporting the value of miner assets and AI-pivot deals.

What did Apple report?

Fiscal Q3 EPS of $2.02 (vs. $1.88 expected) on $109.4 billion revenue with iPhone sales up 22% — but weak guidance citing supply constraints sent shares down more than 6% after hours.

How fast did AWS grow?

37% year-over-year, its fastest pace in 18 quarters, beating expectations of about 31% and contributing 60% of Amazon’s operating income.

Which miners benefit most from the AI trade?

Miners with large energized sites and strong grid interconnects — the profile behind IREN’s verified $2.8 billion Microsoft/Nvidia arrangement. Smaller miners without expandable power footprints benefit mostly in narrative terms.

Does AI demand offset low Bitcoin prices for miners?

Only partially. AI deals monetize real estate and power, but core mining margins still depend on BTC price, fees, and difficulty — all currently under pressure with Bitcoin near half its all-time high.
