Palantir Billionaire Peter Thiel Has 42% of His Portfolio in These 2 Artificial Intelligence Stocks - Yahoo Finance

Peter Thiel, the co-founder and Chairman of the Board of Directors of Palantir Technologies, has invested in several winning companies over the years. He was an early investor in Meta Platforms when it was known only as Facebook, and LinkedIn before Microsoft bought it.

Given his successful track record, Thiel's investments are worth paying attention to. His investment firm, Thiel Macro LLC, recently disclosed new holdings in several stocks connected to the artificial intelligence (AI) sector.

Missed AI's "Act 1"? Act 2 Could Be 15x Bigger. Most investors think they missed the AI boat because they didn't buy Nvidia in 2005. But according to our analysts, we're only at the end of "Act 1"—the R&D phase. "Act 2" is the global rollout. Continue »

Two of these comprise a substantial 42% of the portfolio by market value. They are Amazon (NASDAQ: AMZN) and Vistra Corp (NYSE: VST). Here's a deeper dive into these companies to help investors evaluate whether to follow Peter Thiel's lead and buy shares.

Why Amazon is an appealing AI stock

Peter Thiel's Thiel Macro had no investments in the first quarter of 2026. Suddenly, Thiel loaded up on eight stocks in Q2, with Amazon as its largest holding. This one company comprised 28% of the fund. Notably, the remaining seven were energy-related stocks, leaving Amazon as the outlier.

Amazon may be known as an e-commerce titan, but its position as the world's top cloud computing company, with an impressive 28% market share, is a key factor making it a compelling AI investment. Notably, the company's CEO, Andy Jassy, built the Amazon Web Services (AWS) division into a cloud powerhouse before being selected for the CEO role.

AWS is just one of the many businesses Amazon owns, and it houses the tech titan's artificial intelligence infrastructure. This is the vehicle for delivering AI to other organizations, such as its Seller Assistant, an agentic AI tool helping businesses sell their products. Amazon's goal is for AWS to make it as easy for organizations to construct AI systems as it is to build a website. It's making rapid strides toward achieving this objective.

For example, Amazon reported its AI business exceeded a $25 billion annual revenue run rate in the second quarter, representing a triple-digit year-over-year increase. This contributed to AWS sales expanding 37% year over year in Q2, the fastest growth in 18 quarters.

This performance is just the start. Industry forecasts expect the global artificial intelligence market to expand from $618 billion in 2026 to a whopping $1.4 trillion by 2032. That kind of growth suggests Amazon could sustain several years of strong performance in its AI business, especially given its role as a key provider of cloud computing infrastructure.
