3 Stocks That Could Join the Trillion-Dollar Market Cap Club Next Year

In This Article:

Believe it or not, there are now nine publicly traded U.S. companies worth $1 trillion or more.

They are Apple, Microsoft, Nvidia, Amazon, Alphabet, Meta Platforms, Tesla, Broadcom, and Taiwan Semiconductor. Berkshire Hathaway was briefly a member of the group, but its market cap has dipped slightly below the threshold this month. Still, it seems likely that it will rise back above the mark again, effectively making the conglomerate the tenth trillion-dollar company.

Just a few years ago, there weren't any U.S. companies worth more than $1 trillion, and at the end of 2023, there were only five (the first five named on the list above).

Thanks to the artificial intelligence (AI) boom, a resilient U.S. economy, and falling interest rates, membership in the club isn't quite as exclusive as it once was. Assuming this bull market continues in 2025, there are a few more companies that could reach a $1 trillion market cap -- including these three.

1. Walmart

Walmart (NYSE: WMT) has been one of the biggest surprises on the stock market over the last few years as the brick-and-mortar retail giant reinvented itself as a cohesive omnichannel business with growth avenues in e-commerce, a third-party marketplace, and advertising. Meanwhile, it performed well in the inflationary period thanks to its strength in groceries and its economies of scale, which allowed it to beat competitors on price and also pass along price increases to customers.

Walmart's market cap has more than doubled over the last three years, and the stock was up 81% year to date through Dec. 18 thanks to solid growth on the top and bottom lines. Wall Street also seems to be rerating the stock in recognition of the value of its competitive advantages. Walmart now has a market cap of $763.8 billion.

From there, its market cap would have to increase by 31% in 2025 for it to cross the $1 trillion threshold. That won't be an easy climb, especially after this year's steep rise, but it could get there.

Walmart is unlikely to deliver 31% earnings growth, but it could benefit from continued multiple expansion, as its P/E of 39.2 is still a significantly lower valuation than Costco's P/E of 57.

2. Eli Lilly

Eli Lilly (NYSE: LLY) is now the most valuable pharmaceutical company in the U.S. thanks to the strong sales of its weight-loss and diabetes drugs Zepbound and Mounjaro (both of which are brands of the same compound, the GLP-1 inhibitor tirzepatide). It nearly reached a $1 trillion market cap earlier this year, but broader pressure in the pharma sector sent the stock lower in the second half of the year.
