The bull market recently raced into its third year, as the S&P 500 and the Nasdaq each surged to new record highs in 2025. Technology stocks, particularly those well-positioned in the artificial intelligence (AI) market, have been powering this momentum. Why AI? Because this newish technology promises to revolutionize the way tasks are done -- from the simplest to the complex -- and result in great efficiency and innovation for companies. Investors are betting that will result in earnings growth and stock price performance -- and it already has for many.
The big question now is how long this movement will last. Well, history has some good news for us. A look at the 11 bull markets since World War II shows us the average length is more than five years, according to research by Ryan Detrick, chief market strategist at Carson Group. Detrick also points out that the average bull market in this time period has delivered an increase of more than 191% -- considering that over the past three years the S&P 500 has climbed about 70%, the current bull market may have plenty of room to run.
All of this suggests the Nasdaq, powered by some of today's biggest growth stocks, may soar in 2026. Here's the one AI stock to buy before it does.

A no-brainer bet on AI
This particular company is so essential to the field of AI that it represents a clear no-brainer bet on the industry. If AI demand continues as expected, it's very likely this player will score a major win. The company I'm talking about is Nvidia (NVDA +1.72%), the world's biggest AI chip designer.
So, first, let's talk about what this player has accomplished so far. Nvidia has built this AI empire because it had the foresight to get in on the space early, allowing it to develop leadership, and the company also rapidly expanded into a variety of AI products and services. This made it the "go-to" choice for the AI customer searching for the best and most complete platform.
All of this has resulted in mind-blowing earnings growth, with revenue and net income soaring in the triple-digits in the latest full year. And in recent quarters, the company has delivered double- and triple-digit earnings growth.
Still, you may look at Nvidia's 1,000% gain over the past three years and wonder if it really represents a growth bet moving forward. After all, it's much more difficult for a player to grow from these levels -- from an earnings and share price perspective -- than from the lower levels of a few years ago.

Key Data Points
Surging chip demand
Though Nvidia may not surge to the same extent that it did in the past in a very short period of time, this company still has what it takes to offer investors significant growth. In the latest quarter, Nvidia's revenue growth accelerated, and the company spoke of surging demand for its chips. On top of this, its biggest customers, from Microsoft to Alphabet, spoke of demand from their customers for compute -- this implies they will continue to turn to Nvidia for chips to meet that demand. And the fact that these are companies with solid earnings track records suggests they have what it takes to continue investing.
It's also important to consider the phase of AI we're in now and what's ahead. Today and over the next few years, AI customers are scaling up their platforms. Nvidia chief Jensen Huang predicts AI infrastructure spending might reach $4 trillion in five years. As this unfolds, customers will start to actually apply AI to their needs -- and this will continue well into the future. Nvidia's chips are central to all of this, powering the training of models and then fueling them as they do their job of solving problems. Meanwhile, Nvidia innovates on an annual basis to maintain its leadership position.
This stock could lead the Nasdaq higher
Nvidia, trading for 38x forward earnings estimates, may not be the cheapest AI stock around, but it's worth the premium due to all of the points I've mentioned above. And if history is right and the Nasdaq soars in 2026, Nvidia could lead the way -- that makes it an excellent buy right now.
Finally, even if history is wrong, the great news is that Nvidia, thanks to its AI leadership, still could deliver impressive growth over the long term.
