The newest artificial intelligence chip stock in the $1 trillion club is Broadcom ( AVGO 24.43%). The stock passed the milestone after a stellar fourth-quarter earnings report on Dec. 12. Here's how the company became a leading AI chipmaker worth 13 figures.

Broadcom backed up Nvidia’s projections that large technology companies have an appetite for building data centers with up to 10 times as many AI chips as today.

Two prominent companies in this area are quantum computing company IonQ (NYSE: IONQ) and semiconductor-giant Nvidia (NASDAQ: NVDA). Through Dec. 11, IonQ's share price was up around 140%, and Nvidia's had risen about 180% in 2024.

However, billionaire David Tepper sold Nvidia in the third quarter and bought a shocking AI stock: electric utility Vistra ( VST -0.13%). That was a bad pun, but Tepper is a good case study for investors because his hedge fund Appaloosa more than doubled the return of the S&P 500 ( ^GSPC -0.00%) in the last three years.
