The four largest US technology companies head into earnings this week with roughly $700 billion in committed capital expenditure on the line, and Wall Street is no longer willing to take AI revenue on faith. Microsoft reports its fiscal third quarter on Wednesday after the close, with Alphabet, Meta and Amazon following through the week and Apple landing Thursday. Almost all of the spending sits in AI infrastructure.
The pressure is being framed in starker terms than at any point in the current cycle. "Wall Street's AI boom is heading into a quote, ROI reckoning," Jaeden Schafer said on the podcast, citing a note from Dan Ives' colleague Dan Ives at Ramsey Theory Group flagging a turn in sentiment as analysts hunt for evidence that capex is converting into revenue rather than just margin compression.
Alphabet illustrates the squeeze most clearly. First-quarter earnings per share are projected to fall 6.4% year over year even as revenue climbs to $106.9 billion, with the company's $175 billion to $185 billion AI capex line grinding through its operating margins. The growth story is intact; the profitability story is the one investors are now interrogating.
Key facts
- 01Microsoft, Alphabet, Meta and Amazon are committing roughly $700 billion in capex this year, almost all of it for AI infrastructure.
- 02Alphabet's Q1 EPS is projected to drop 6.4% year over year despite revenue climbing to $106.9 billion, with $175–185 billion in AI capex compressing margins.
- 03Meta spent $72 billion on capex last year and is guiding up to $115 billion in 2025, raising pressure to show direct AI revenue attribution.
- 04Wall Street is split on Microsoft: Truist reiterated a buy with a $675 target, while Oppenheimer cut its target to $515 ahead of Wednesday's report.
Meta faces a sharper version of the same question. The company spent $72 billion on capex last year and has guided up to $115 billion this year, much of it directed at frontier model training and AI tooling embedded in its messaging apps. Schafer argued that consumer traction for those products has lagged rivals. No one really believes that Meta AI is as good, he said, noting that Meta's assistants are not driving the kind of agentic productivity use cases that justify paid subscriptions elsewhere in the market.

That gap between spend and monetisation is what makes the call defensive. Mark Zuckerberg has long argued AI underpins Meta's recommendation algorithms, but the market is now asking for line-item attribution to AI workloads rather than narrative. Free, embedded chat features inside WhatsApp and Instagram do not produce the per-seat economics that have boosted competitors with enterprise distribution.
Microsoft's report is shaping up as the week's main event. It lands two days after the company lost its exclusive cloud arrangement with OpenAI, removing a clause that had reserved the lab's workloads for Azure. Azure growth has been guided at 37% to 38%, and any deceleration would land directly on the stock. If this decelerates, this is going to put a lot of pressure on their stock and on their company and kind of their direction overall, Schafer said.
The split on the sell side captures how binary the setup feels. Truist this week reiterated a buy with a $675 price target, while Oppenheimer cut its target to $515. Both views cannot survive Wednesday's print intact, and the gap between them — roughly 30% — is unusually wide for a mega-cap heading into a quarterly update.
The broader read across the four reports will set the tone for AI infrastructure spending into the second half of the year. If margins compress further without clear revenue attribution, the hyperscalers will face harder questions about pacing their build-outs. If the numbers hold, the $700 billion capex cycle gets a fresh green light and the debate moves on to 2026 commitments.
