As We Give Thanks, AI and Mag 7 Take Cash to the Bank
Market volatility resurfaced last month as speculation intensified over whether an AI bubble may be forming—and potentially bursting. Yet despite the jitters, equity markets remain solidly positive for the year (S&P 500 +16.5%, NASDAQ +21.0%, Dow +12.2%) – see S&P 500 chart below. A significant portion of the gains have been powered in large part by ongoing strength in the Magnificent 7. Standouts such as NVIDIA (+31.8%) and Alphabet (+68.1%) have been instrumental in carrying the broader indices higher.
Even with these sizable year-to-date gains, memories of the 2000 Tech Bubble and 2008 Financial Crisis resurfaced and prompted investors to temporarily tap the brakes. Mid-month, the NASDAQ retreated roughly -9% from its October peak. After a month-end bounce, the S&P 500 finished essentially flat (+0.1%), the NASDAQ slipped -1.5%, and the Dow eked out a +0.3% increase.
OpenAI and the $1.4 Trillion Question
At the center of the AI controversy sits OpenAI, parent of the three-year-old technology toddler, ChatGPT (Generative Pre-trained Transformer), which now boasts more than 800 million global users (see chart below). The company reportedly runs at a $20 billion annual revenue pace, yet faces difficult questions about how it intends to fund its staggering $1.4 trillion AI infrastructure commitments.
Those concerns came to a head when tech investor Brad Gerstner pressed CEO Sam Altman on his podcast last month. Instead of answering how OpenAI plans to underwrite such an enormous buildout, Altman childishly shot back defensively:
“If you want to sell your shares, I’ll find you a buyer.” (See clip here — or full interview here)

OpenAI is a key player, but just one component in the vast—and rapidly expanding—web of global AI infrastructure. Gartner, a global research and advisory firm, forecasts $2 trillion of AI investment in 2026, while NVIDIA CEO Jensen Huang recently said:
“Over the next five years, we’re going to scale into… effectively a $3 to $4 trillion AI infrastructure opportunity.”
These provocative “Is this a bubble?” questions make for great headlines, but to truly evaluate AI sustainability, it’s wise to follow the classic Watergate guidance from of All the President’s Men character, Deep Throat (FBI Associate Director, Mark Felt), who tells journalist Bob Woodward to “follow the money,” if he wants to get to the bottom of the Watergate scandal.
The same principle applies to investors who follow the money – the picture looks very different from past bubbles.
Forget Pets.com—Today’s AI Buildout Is Being Funded by Cash-Rich Titans
Unlike the flimsy, profitless internet startups of the late 1990s—companies that raised billions based on “eyeballs” and cocktail-napkin business plans—the current AI buildout is being financed largely by profitable cash-generating giants.
Yes, some firms like Oracle (ORCL) are leaning on debt financing for data-center expansion. But the overwhelming majority of AI capex is being funded by customers and by the cash flow of the Magnificent 7, a group with the financial firepower to sustain multi-year spending without relying heavily on capital markets.
This dynamic alone separates today’s environment from classic bubble conditions.
Do the Magnificent 7 Really Deserve a $22 Trillion Valuation?
The Mag 7 represent only 1% of S&P 500 constituents yet account for a massive 35% of the index’s market value. That concentration understandably raises eyebrows, evoking historical parallels to the “Nifty Fifty” of the 1970s or the “Four Horsemen” of the 1990s.
But headline concentration can be misleading—because the fundamentals tell a very different story. Here are some of the major disparities:
1.) Mag 7 Share of Profits Matches Their Share of Market Value: The Mag 7 collectively contribute $22 trillion of the S&P 500’s $58 trillion total value (below). Said differently, the market values and weightings of the Mag 7 equate to about $22 trillion and 37% of the S&P 500, respectively:
· Nvidia Corp: $4.3T & 7.0%
· Apple Inc.: $4.1 T & 6.7%
· Alphabet Inc.: $3.9 T & 6.3%
· Microsoft Corp.: $3.7 T & 5.9%
· Amazon.com Inc.: $2.5 T & 4.0%
· Meta Platforms Inc.: $1.6T & 2.6%
· Tesla Inc.: $1.4T & 2.3%
· TOTAL: $22T / 37%

Conveniently (and importantly), the Mag 7’s roughly $747 billion in annual cash flow (see table below) is a good proxy for their profit contribution to the $2 trillion in S&P profits.

The $747 billion in Mag 7 cash flows divided by the $2 trillion in S&P 500 coincidentally also equates to 37% ($747B/$2T).
These calculations of the Mag 7 are not bubble math—these calculation comparisons are rational math. Arguments could be made that Mag 7 market values are actually undervalued (not in bubble territory) and should appreciate to a higher percentage of the S&P 500 weightings because these 7 stocks are growing sales and profits faster than compared to the other “absentee” 493 stocks in the index.
2.) Mag 7 are Swimming in Cash: That $747 billion in annual cash flow is on track to hit a jaw-dropping $1 trillion, giving these firms ample capital to fund AI buildouts without substantially accessing the equity or credit markets. The ability to self-fund a multi-trillion-dollar infrastructure expansion is the opposite of bubble behavior.
3.) Valuations Are Elevated—but Far from Bubble Territory: During the 2000 Tech Bubble, many leading tech names traded at 100x+ earnings (See also: Rational or Irrational Exuberance. Today, the Mag 7 trade at a median forward P/E around 30x. Expensive? Historically, yes, versus long-term averages, but nowhere near historical extremes. Relative to growth, profitability, and cash flow, valuations are far more grounded today than during prior manias.
The bottom line is there is plenty to be thankful for and bubble fears are overstated. Despite pockets of AI froth, the underlying economic engine powering AI adoption is real, profitable, and well-capitalized. When investors follow the money, they discover:
· The Mag 7 generate over one-third of S&P 500 profits
· They generate and hold hundreds of billions in cash
· They largely fund their own AI capital expenditures
· Valuations remain far below bubble-era extremes
Investors have a lot to be thankful for. And while volatility will likely continue, the ingredients for a classic, catastrophic AI bubble are noticeably absent. For disciplined, long-term investing strategies like those employed at Sidoxia Capital Management, this environment still offers abundant opportunity—without the need to fear a pricked AI balloon anytime soon.
