Currently, four companies have market caps above $3 trillion: Nvidia (NVDA 1.36%), Apple (AAPL 1.86%), Alphabet (GOOGL 1.23%) (GOOG 1.29%), and Microsoft (MSFT 0.29%). By the end of next year, that number is likely to rise to seven.
Let's look at three stocks that could hit the $3 trillion mark in 2026.

1. Amazon
With a $2.4 billion market cap, Amazon (AMZN 1.28%) is the best-positioned company to join the exclusive club next year, needing a 25% gain. While the stock has been a laggard the past few years, the company is well-positioned heading into 2026.
NASDAQ: AMZN
Key Data Points
One of the big reasons Amazon's stock has lagged is that while its cloud computing unit, Amazon Web Services (AWS), is growing quickly, its growth has trailed that of Microsoft's Azure and Alphabet's Google Cloud. However, AWS' revenue started to accelerate last quarter, up 20%, and the company is increasing its spending on artificial intelligence (AI) infrastructure to meet increasing demand. Meanwhile, its big Project Rainier for Anthropic continues to ramp up, and it recently signed a $38 billion deal with OpenAI. It's also in talks with OpenAI about an investment that would see the company use its custom Trainium AI chips.
Meanwhile, the company's e-commerce business is seeing strong operating leverage from its investments in robotics and AI. Trading at a forward price-to-earnings (P/E) ratio of 28 times, the stock has room to run next year.
2. Meta Platforms
With a $1.7 trillion market cap, Meta Platforms (META 2.43%) has more work to do than Amazon, needing a more than 75% gain in 2026 to reach $3 trillion. However, don't count the stock out. It's the cheapest of the megacap tech stocks, trading at a forward P/E of below 22 times, while also growing quickly, with its revenue climbing 26% last quarter.
Meta's stock hit a speed bump late in the year, as investors worried about its spending. However, the company is reportedly set to slash spending on its money-losing metaverse projects to focus more on AI, where it has been seeing a nice return.
NASDAQ: META
Key Data Points
Meta has seen a big boost from AI, as the company has been using the technology to improve its recommendation algorithm, leading to users spending more time on its sites. At the same time, it's using AI to help advertisers create better campaigns and improve ad targeting. The positive impact of this could be seen in Q3, as its ad impressions jumped 14%, while ad prices climbed 10%, as its ads have become more effective. It's also just starting to introduce ads to its WhatsApp and Threads platforms, which should help drive future growth.
If the company can cut back on some of its more wasteful spending, easing investor concerns, and continue to grow at its current pace, the stock could hit $3 trillion next year.
3. Broadcom
Broadcom (AVGO 1.35%) is another company that could hit the $3 trillion mark in 2026. Its path looked a little easier earlier in the month before its stock lost nearly 20% of its value to bring its market cap to $1.6 trillion. However, the company has an explosive growth opportunity in front of it that could propel its stock much higher in 2026.
Broadcom has been enjoying strong growth in its networking portfolio due to the data center buildout, but its biggest opportunity is in helping customers design custom AI application-specific integrated circuits (ASICs). ASICs are preprogrammed chips designed for specific tasks, and as such, they can outperform general-purpose graphics processing units (GPUs) and be more energy efficient. This last part is particularly important for inference, which is an ongoing expense, and customers are increasingly turning to it as a cheaper alternative to Nvidia.
NASDAQ: AVGO
Key Data Points
Broadcom helped Alphabet design its highly successful Tensor Processing Units (TPUs), which has led other companies to flock to its services. It recently signed a huge deal with OpenAI that could be worth hundreds of billions of dollars, while Anthropic will deploy $21 billion in Alphabet's TPUs in 2026. Meanwhile, it said its original three customers could be an up to $90 billion opportunity in fiscal year 2027. In addition, there are reports that Apple is working with Broadcom on an AI chip that could be ready for mass production next year.
For a company that delivered just below $64 billion in total revenue last fiscal year (ending in October), that's just a huge growth opportunity. If Broadcom can deliver on this growth and Apple does indeed start deploying Broadcom-designed AI chips, the stock could skyrocket next year and hit a $3 trillion market cap.
