Meta and Microsoft report earnings this week.
I don’t think revenue will be the biggest story.
I think AI spending will.
Just look at what happened last week.
Google reported another strong quarter.
Cloud revenue kept growing.
The company raised its AI spending again.
Investors didn’t celebrate.
They started asking when all this spending starts making money.
Now it’s Meta’s and Microsoft’s turn.
The numbers are getting hard to ignore.
Meta plans to spend $66 billion to $72 billion on capital expenditures this year.
Microsoft plans to spend about $120 billion this fiscal year.
Alphabet just raised its capex guidance again to around $195 billion to $205 billion.
Across the hyperscalers, AI infrastructure commitments are now measured in the hundreds of billions of dollars.
Some estimates put AI related commitments at $1.65 trillion, much of it sitting outside the traditional debt numbers investors usually watch.
That is a huge bet.
Nobody has ever built this much computing power this fast.
Wall Street isn’t asking if AI is real anymore.
That debate is over.
The question is much simpler.
When does this turn into cash?
Meta has one advantage.
Its advertising business keeps printing cash, and AI is already helping improve ad targeting, engagement, and monetization.
If Zuckerberg can show those gains are accelerating while explaining why another jump in spending makes sense, investors may look past another massive capex number.
Microsoft has a different test.
Everything comes back to Azure.
If Azure growth stays strong, investors will probably accept another year of building data centers.
If Azure slows, people will immediately ask why spending keeps going higher.
That is why guidance may matter more than the earnings report.
Wall Street already knows these companies are spending record amounts.
It wants to know when free cash flow starts catching up.
I also think something changed over the last few months.
At the beginning of the AI boom, companies were rewarded for announcing bigger spending.
Today investors want proof.
Proof that new data centers fill up.
Proof that GPUs stay busy.
Proof that AI customers keep paying.
Proof that margins recover after all this investment.
That is a very different market.
Meta and Microsoft can beat earnings this week.
They can beat revenue.
They can even raise guidance.
But if management can’t answer one simple question, none of that may matter.
When does the biggest AI spending spree in history finally start paying shareholders back?
