TL;DR — Microsoft, Alphabet, Amazon and Meta are now guiding to a combined 2026 capex figure north of $700 billion, most of it AI infrastructure. Two of the four, Alphabet and Amazon, reported negative free cash flow this earnings season. A third, Meta, generated just $784 million. Only Microsoft is still comfortably cash-flow positive.
Add up the 2026 capital expenditure guidance from the four largest AI infrastructure spenders and the total comes to somewhere north of $700 billion, spread across fiscal years that don’t quite line up but land in the same twelve-month window. That number was unthinkable three years ago. What’s more striking this earnings season isn’t the size of the bill. It’s that two of the four companies paying it now have negative free cash flow, and a third is down to less than a billion dollars.
The Four Bills
Alphabet raised its full-year 2026 capex guidance twice this year, most recently to $195-205 billion, up from $180-190 billion, after quarterly capex hit a record $44.9 billion, roughly double the year-ago quarter. Amazon raised its own guidance to approximately $220 billion, with trailing-twelve-month property and equipment purchases already at $169.0 billion, up from $102.9 billion a year earlier. Meta raised the low end of its range, keeping the top at $145 billion. Microsoft doesn’t guide a full fiscal year number the same way, but its fourth-quarter capital spending hit $41 billion, and CFO Amy Hood told analysts to expect “over $50 billion” in the current quarter alone, a run rate that would put its own annualized figure well past $150 billion if sustained.
- Alphabet: $195-205 billion guided for 2026, up from $180-190 billion.
- Amazon: roughly $220 billion guided for 2026.
- Meta: up to $145 billion guided for 2026.
- Microsoft: $41 billion last quarter alone, over $50 billion guided for the current one.
Who’s Still Generating Cash to Pay For It
This is where the four companies split. Microsoft’s free cash flow fell 23% to $19.6 billion last quarter, a real decline, but still comfortably positive by a wide margin. Alphabet’s free cash flow went negative $5.9 billion the same earnings season, even with a record quarter of paper investment gains padding its reported net income. Amazon’s free cash flow turned negative $7.6 billion on a trailing-twelve-month basis, a 142% decline from the positive $18.2 billion it generated over the equivalent period a year earlier, even as operating cash flow itself grew 33%. Meta generated just $784 million in free cash flow this quarter, positive, but barely, on $60.8 billion of revenue.
Four companies are spending at nearly the same scale. Only one of them is still generating enough cash to comfortably cover it.
Why None of Them Are Slowing Down
The stated logic is consistent across all four earnings calls: demand is outrunning supply. Alphabet’s Google Cloud backlog reached $514 billion, up $50 billion in a single quarter, and CFO Anat Ashkenazi has already warned that 2027 capex will “significantly increase” beyond this year’s raised guidance. Amazon’s CFO Brian Olsavsky said AWS capacity for 2027 is “already largely reserved.” Alphabet CEO Sundar Pichai called the moment “very early innings of what feels like a secular shift.” None of that framing is new; it’s the same rationale Third Pole tracked when Meta’s capex guidance first doubled earlier this year, and the same one underpinning the hardware buildout at Alphabet specifically.
What’s changed is that the bill has grown large enough to visibly dent free cash flow at three of the four companies paying it, not just compress margins on paper. Microsoft is the only one of the four with enough cash generation to absorb a $50 billion quarter without going negative. Whether Alphabet, Amazon and Meta can grow into their own numbers the way Microsoft has so far is the question their next two or three quarters of results will actually answer, not this one.
