A Reddit investor dumped NVDA and GOOGL arguing AI cloud revenue of $70 billion falls ten times short of the $636 billion hyperscalers need for historical returns.
QQQ's 21% year-to-date return beat both GOOGL and MSFT, meaning the index he could have held outperformed two of his three exits.

Stock traders and investors everywhere: here's some food for thought. A poster called "u/soukstah" in the r/stocks community on Reddit argued that consumer and enterprise artificial intelligence (AI) spending needs to reach nearly $2 trillion, according to r/stocks community, Reddit. He sold his last shares of NVIDIA Corporation (NASDAQ:NVDA), Alphabet Inc. (NASDAQ:GOOGL) and Microsoft Corporation (NASDAQ:MSFT) over that number. The poster credited the Financial Times for the underlying figures.
His own summary captured the mood. "I mean the economics never made sense at these GPU prices, but it's just getting so ridiculous that even riding the last hours of the party feels wrong." For anyone who owns NVIDIA, Alphabet or Microsoft shares, the open question is whether being right about that arithmetic says anything about when to sell.
What a $2 Trillion Gap Could Mean
The poster's math starts with return on invested capital (ROIC). If hyperscalers like Alphabet and Microsoft want their historical 30% ROIC, they need $636 billion annually, according to r/stocks community, Reddit. On Reddit, the r/stocks poster called that ten times the current run rate of roughly $70 billion in AI cloud revenues, according to r/stocks community, Reddit.
Model research labs want to earn money too, he added, and that pushed his spending estimate into the trillions. He concluded that software sales of that size aren't coming anytime soon because consumers are used to free digital products. That logic took him out of NVIDIA, Alphabet and Microsoft.

Many successful investors eventually reach the same moment. The saving is done, the portfolio is built, and the question quietly changes from how much can I grow this to how much can I take out? Get that second question wrong and decades of good investing can come apart in a handful of years.

Sustaining the AI buildout would require an AI market approaching $6 trillion annually by 2031, according to Bain & Company's latest technology report released at the end of September. By Bain & Company's math, consumer and enterprise AI together leave about $4.2 trillion of new revenue still to be found, according to Bain & Company. That puts the Reddit poster at the conservative end of the case against NVIDIA, Alphabet and Microsoft.

Market Reaction Split Into Two Stories
NVIDIA stock was up 25% year to date as of October 1, 2026, at $231.82, carrying nearly all of the gains among the three names the poster sold. Meanwhile, Alphabet stock was up 8% year to date, far behind NVIDIA.
Microsoft stock was up 7% year to date, the worst showing of the three, while the Invesco QQQ Trust (NASDAQ:QQQ) was up 21%, ahead of both Alphabet and Microsoft. In other words, the index the poster could have held instead outperformed two of the three stocks he sold. For broader-market context, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) was up 12% year to date as of October 1.
Over a one-year window, Alphabet stock was up 40%, while Microsoft stock was up just 0.4%. Those figures show the party was never general, and part of the exit meant leaving Alphabet and Microsoft, two stocks that fell behind this year while NVIDIA stock compounded.
Bear Case: Right Math, Open Timing
On paper, the argument for betting against NVIDIA, Alphabet and Microsoft holds together, since Bain & Company's version of the shortfall is larger than the poster's. A revenue gap that wide is a real risk if AI spending is what lifts NVIDIA, Alphabet and Microsoft shares.
Timing is where that case thins out, because Bain & Company's figures describe a shortfall stretching to 2031, and he sold NVIDIA, Alphabet and Microsoft all at once, as Bain & Company concludes that new categories of AI applications have to arrive to pay for the expansion, a statement about what hasn't happened yet.
Bottom Line: What Would Settle It
The evidence that could settle this argument is whether new AI applications start producing the consumer and enterprise revenue Bain & Company says is still missing. Shareholders could look for signs that customers of NVIDIA, Alphabet and Microsoft are paying for AI products at a scale that begins closing the gap.
Until that evidence arrives, NVIDIA, Alphabet and Microsoft remain two different stories inside one argument. Investors weighing their exposure should adjust their holdings carefully given that the arithmetic runs to the end of the decade while the returns on these three stocks have already split.
