12 Best Stocks to Buy for the AI Boom in the Second Half of 2026

In this article, we will discuss the 12 Best Stocks to Buy for the AI Boom in the Second Half of 2026.

Artificial intelligence continues to dominate Wall Street’s investment narrative heading into the second half of 2026. While the recent flare-up in US-Iran and Russia-Ukraine conflicts may have investors closely monitoring inflation and interest rates, the largest tech companies continue to commit big bucks to AI infrastructure spending to support the growing compute demand from AI models and applications.

Speaking on CNBC on July 7, Deepwater Asset Management Managing Partner Gene Munster said that AI buildout is still in its early innings, and that AI-related capex growth rate for 2026, 2027, and 2028 will be higher than people expect. The Deepwater analyst noted that capex is one of the key metrics related to the health of the AI stocks trade.

“The Street is looking for 23% capex growth from the hyperscalers for next year…a few weeks ago, that was 17%…the numbers are going to be up around 37%, so much higher,” said Munster.

According to the analyst, the actual AI use remains limited at this point, and so a massive growth opportunity still lies ahead. Munster cited autonomous ride share as an example. He noted that autonomous rides are going to account for only 0.6% of the total ride share market in 2026 and about 1.5% in 2027. “So that’s on the physical AI side, not to mention on the application side,” the analyst said.

Wall Street expects AI spending to continue driving corporate profits and equity performance for the foreseeable future. In 2026, S&P ​500 earnings are expected to rise by more than 26%, according to LSEG IBES.

Companies across diverse industries, including semiconductor, cloud infrastructure, software, and cybersecurity, are positioning themselves to benefit from AI adoption. For investors, the opportunities are vast and extend beyond the mega-cap tech leaders that have driven much of the recent market gains.

That said, let’s explore some of the best stocks to buy for the AI boom in the second half of 2026.
