7 Companies Worth $23 Trillion: The Simplest Way to Own Them

Friendly note before we begin: this isn’t financial advice; it’s simply how we see the world. We share our opinions here the way we’d share them over coffee. Investing in the stock market is risky, so please do your own research and decide what’s right for you.

You’ve Probably Heard of the MAG 7

They’re seven of the largest companies in the United States, and by market value, seven of the largest on earth. Together they’re worth more than $23 trillion. When they move, the entire stock market moves with them. Their names are on the devices in your pocket, the search bar you used this morning, the cloud running half the internet, and the chips training the AI models everyone is talking about.

Here they are:

• Apple (AAPL): the iPhone, and the services empire built around it.
• Microsoft (MSFT): the software and cloud backbone of modern business.
• Alphabet (GOOGL): Google, YouTube, and one of the world’s great advertising machines.
• Amazon (AMZN): e-commerce and AWS, the cloud that powers a staggering share of the internet.
• Nvidia (NVDA): the chips nearly every AI breakthrough runs on.
• Meta (META): the social platforms where billions of people spend their hours.
• Tesla (TSLA): electric vehicles, and a long-term bet on autonomy and robotics.

A few years ago, the market’s shorthand for big tech was FAANG: Facebook, Apple, Amazon, Netflix, Google, a term coined by Jim Cramer back in 2013. But the AI era changed the cast. In 2023, Bank of America’s Michael Hartnett gave the new lineup its name: the Magnificent Seven. Netflix stepped out; Microsoft, Nvidia, and Tesla stepped in. It wasn’t just a rebrand; it was the market admitting that artificial intelligence and cloud computing had replaced social media and streaming as the defining themes of our time.

Why We Think the Seven Could Become Ten

Here’s our honest view: the Magnificent Seven are the hyperscalers of this era. Each one has its own angle on the future (chips, cloud, devices, advertising, commerce, social, autonomy), and we believe they’re all positioned to keep winning their respective races.

But seven may not be the final number. We firmly believe this group could grow into a top ten as the new generation of AI companies matures. Anthropic and OpenAI are building the models the entire industry is racing to match. And SpaceX, further out, may one day belong in this conversation too.

We don’t know where any of them are going. Nobody does. What we do know is that you can’t buy shares of Anthropic, OpenAI, or SpaceX in a brokerage account today. They’re private companies. So the practical question is: how does an ordinary investor own a piece of the giants that are available?

You have three doors into the same building. Each one just turns up the concentration.

Option 1: The S&P 500, the Safest Door

The simplest way to own the Magnificent Seven is to own the whole market. An S&P 500 index fund or ETF gives you a slice of the 500 largest companies in America, and because the index is weighted by size, the giants automatically take up the most room.

Here’s the part most people don’t realize: the Magnificent Seven make up roughly a third of the entire S&P 500. Nvidia alone accounts for around seven percent of the index. So if you already own an S&P 500 fund in a retirement account: congratulations, you’re already one of the largest Mag 7 investors on earth, and you didn’t even have to pick a stock.

This is the calmest of the three options. You get the giants plus hundreds of other companies (banks, hospitals, railroads, consumer brands) smoothing out the ride.

Option 2: QQQ, a Little Bolder

The Invesco QQQ ETF tracks the Nasdaq-100: the 100 largest non-financial companies on the Nasdaq exchange. It’s heavily tilted toward technology and growth, and all seven Magnificent stocks sit in its top holdings.

The Mag 7 make up around 40% of QQQ, meaningfully more concentrated than the S&P 500, with the remaining 60% spread across the next generation of tech leaders in AI, cybersecurity, cloud, and biotech. There’s a quiet bonus here too: because the index lets its winners grow, the QQQ has a habit of holding tomorrow’s giants before they get their own acronym.

A little more concentration, a little more growth tilt, a little more swing in both directions.

Option 3: MAGS, the Pure Play

If you want the Magnificent Seven and nothing but the Magnificent Seven, there’s an ETF built for exactly that: the Roundhill Magnificent Seven ETF (MAGS). One hundred percent of the fund is the seven companies, held in roughly equal weight (around 11 to 17 percent each), so no single name dominates the way Nvidia dominates the S&P 500.

This is the most concentrated of the three doors, which means the highest highs and the lowest lows. It exists for one belief: that these seven companies, as a group, will keep leading the market. If you share that belief, this is the most direct expression of it.

The Point: You Don’t Have to Pick

Here’s what we love about this approach. You don’t need to decide whether Nvidia beats Microsoft, or whether Tesla’s autonomy bet pays off before Meta’s AI bet does. You don’t need to read earnings reports or time anything. Each of these companies has its angle, and the honest truth is that nobody knows which angle wins biggest.

So don’t pick. Own the theme.

Start with the level of concentration that lets you sleep at night (for most people, that’s the S&P 500), and only move toward concentration if you genuinely understand the bumpier ride that comes with it. The goal was never to find the one perfect stock. The goal is to make sure that as the largest companies in the world keep building the future, you own a piece of it.
