AI stocks have been some of the market’s biggest winners in 2026. By early October, chip stocks alone had soared more than 80% for the year. The past few weeks have been rougher, though. Rising interest rates and worries about how the AI build-out will be paid for have sparked a sharp selloff in tech.

When stocks grow this fast, expectations climb just as quickly. Broadcom CEO Hock Tan, whose company is one of AI’s biggest winners, recently warned that those expectations may have gone too far. On October 12, speaking at a conference in Singapore, he said:

A lot of investors have no clue what they’re investing in, but set very extreme expectations, only to find out that it’s almost like they are in a casino gambling.

The irony in that warning is that Broadcom’s own AI chip revenue more than tripled from a year earlier in its latest quarter. Nvidia CEO Jensen Huang sees things differently. He believes demand for AI infrastructure will outrun the supply of parts needed to build it for years to come.

I think both of them are right, just about different things. Tan is right that many investors buy anything linked to AI and expect it to keep soaring. Huang is right that the demand for AI is real and still growing. The way to stay out of the casino is to own companies already making money from that demand. When a company’s profits are rising fast, its stock price has something solid behind it. Those are the kinds of companies this list focuses on.

10 Fastest-Growing AI Stocks to Buy Now

Methodology

To come up with the list of the top 10 fastest-growing AI stocks to buy now, I looked at AI companies that grew their earnings by more than 30% this year and are expected to grow their next year’s earnings by at least 30%. These companies have a market cap of at least $20 billion, so they are established firms that should stay relevant even if AI infrastructure spending slows down. They are also popular among US hedge funds and are listed in ascending order of their next year’s earnings growth rate.

10. Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM)

Taiwan Semi opens my list because it is the most important foundry in the world. Every AI chip designer depends on the company’s manufacturing expertise to bring its design to reality. Even at a valuation of around $2 trillion, the company continues to grow its earnings at a high rate, projected to be just over 30% for the next year.

The main driver of this growth is the unprecedented demand for compute. In the words of the company’s CEO C.C. Wei, the demand is still far above the company’s capability to supply. Yes, TSM is expanding its capacity, and most of the capacity that hasn’t yet come online is already booked in advance. But that also means investors carry the risk of this demand fading away. While that is unlikely, any negativity surrounding the AI capex will result in the stock price going down, and investors need to be ready for that.

The company has guided to $53.3 billion in revenue at the midpoint, with 2026 growth set to be at 44% in US dollar terms. Going forward, the capital spending between 2026 and 2028 is set to be significantly higher than the past three years, a sign that it expects growth beyond the next year as well. This also gives the stock a premium valuation, and we discussed previously whether the jump in profit justifies TSM’s premium valuation.

9. Vertiv Holdings Co (NYSE:VRT)

Vertiv Holdings Co (NYSE:VRT) is riding the AI data center boom because of its integral role in data center construction. The company supplies the power and cooling equipment that helps keep data centers running smoothly. Its earnings are up 60.15% this year and projected to rise 36.45% next year.

Just like TSM, Vertiv is facing unprecedented demand. To cater to this demand, it is also taking the acquisition route, announcing the completion of its acquisition of UtilityInnovation Group on October 27. This would help the company capture a bigger market by moving upstream toward the grid connection.

Foreign trade policy continues to be a risk for the company, though some recent success in the Supreme Court has allowed the company to file for some refunds of the tariffs it has previously paid. Investors are more concerned about the unpredictable order timing, though, as it makes it hard to predict future earnings reliably. This is also a factor in valuation, with many wondering whether a faster-growing rival, nVent (NYSE: NVT ), is a better valuation play at this stage of the growth cycle.
