There’s never been an infrastructure boom like AI.
Amazon (NASDAQ: AMZN), Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL), Microsoft (NASDAQ: MSFT), and Meta Platforms (NASDAQ: META) are set to spend around $700 billion this year in capital expenditures this year to build out data centers to support demand for AI applications.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »
That’s a number that significantly exceeds annual profit for the group, and Wall Street is starting to get nervous. The latest news from Micron, confirming that memory prices have soared, hasn’t helped the cause.
Microsoft recently hit a 52-week low, and Meta Platforms is near one. Alphabet and Amazon have fared better, but only the Google parent has matched the S&P 500’s return year-to-date.

All of these companies, except for Meta Platforms, have large cloud computing businesses that can justify this kind of spending. Amazon, for example, has gone through similar cycles of capex spending across both its cloud infrastructure business, Amazon Web Services, and its e-commerce business.
In the first quarter, AWS’s revenue rose 28% to $37.6 billion, and it generated $14.2 billion in operating income.
For a business already making more than $50 billion a year from cloud computing, spending to grow it during the AI boom makes sense. Amazon is competing with Alphabet, Microsoft, and others for cloud customers, and it needs to have the chips, servers, data centers, and computing capacity to serve its customers.
These cloud companies are also responding to demand from end customers as AI adoption grows.
Meta’s capex ramp is harder to parse since the company doesn’t have a direct way to monetize it. Some of that spending will power its advertising machine, but the company is also focusing on superintelligence, devices like VR headsets and glasses, and the metaverse. CEO Mark Zuckerberg has said that adding a cloud business is an option.
Will it pay off?
The surge in capex spending has sparked concerns about a bubble, but this looks like a rational decision. All four of these companies are hugely profitable and can easily support such a risk. For the cloud businesses, the growth is evident.
However, it will take time to see if these investments pay off across the cycle. These companies don’t need them to be successful, but all four are trading at very reasonable valuations. If the capex boom delivers results sooner than expected, all four of these stocks have room to make significant gains.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again
In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. If you’d invested $5,000 then, you’d be sitting on $2,499,895 today.*
Now, for the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. It’s a key player in the $1.8 trillion space race, and with the stock recently sitting 20% off its highs, the window to get in early is closing fast.
