The report breaks the investment opportunity into three layers: (1) the enabling layer, (2) the intelligence layer, and (3) the application layer. Listed below are three brilliant AI stocks (one for each layer) that billionaires were buying in the second quarter.

As of the end of the second quarter, Meta had nearly 3.3 billion daily active users (DAUs). That's a huge advantage for the company in many ways, but consider this: Meta is in a position to introduce its AI-powered features to roughly 40% of the world's population.

Chipsets known as graphics processing units (GPUs) are an integral component in the development of artificial intelligence (AI) applications. At the moment, Nvidia (NASDAQ: NVDA) holds an estimated 88% of the AI GPU market thanks to its industry-leading A100 and H100 GPUs.

The two are thriving in the rapidly growing artificial intelligence industry, but only one can be the better AI stock to buy.

Using Wall Street analysts' price targets to determine whether a stock is a buy or a sell isn't the best strategy. While it should help inform investors of how others think of the stock, it shouldn't be the be-all and end-all. One popular artificial intelligence (AI) stock that these analysts (on average) say to sell now is Palantir (NYSE: PLTR).
