Nvidia is due to report earnings on Wednesday, and 'a very broad universe of companies' is tied to the themes that the chip giant represents

Nvidia's earnings report on Wednesday afternoon will be a closely followed market event.

Nvidia was once nearly synonymous with the artificial-intelligence build-out. Now, there are a handful of other AI companies capturing investor attention as they rake in hefty profits.

But earnings results from the chip maker (NVDA), which remains at the heart of the AI boom and has a market value of around $5 trillion, are still a closely watched macro event every three months. Even amid concerns about about circular dealmaking within the AI industry and the sustainability of high data-center spending, analysts expect the company's profits to make up an ever-greater share of the S&P 500 index's SPX overall earnings this year.
