stocks rose today.

AI-related names and software stocks continued to bounce back from Monday's sell-off.

Nvidia stock gained 1.4% ahead of its earnings after the close, which helped push the Nasdaq 1.3% higher on the day.

The S&P 500 and the Dow were up less than 1%.

And reporting after the bell...

NVIDIA reported record sales and income in the January quarter, helping ease concerns over a possible artificial intelligence bubble that have rippled through markets in recent months.

The chip giant reported fourth quarter net income of $43 billion, up 35% from the year earlier quarter, on sales of $68.1 billion, up 20% from a year earlier, easily beating analyst estimates.

Paramount's streaming revenue grew in the fourth quarter, but the company reported weakness in its TV media segment.

The company reported revenue of $8.15 billion for its fourth quarter, in line with analyst estimates.

And Salesforce expects revenue to grow in the current fiscal year at about the same rate as it did the year before, as investors worry about AI's threat to software.

Revenue in its most recent quarter rose 12% to $11.2 billion, in line with analyst expectations.

Prediction market platform CalShe said today that it's fined two users for violating its rules.

One person who ran for governor in California was fined more than $2,000, which includes the amount related to his trades and penalties, while another was asked to pay more than $20,000.

CalShe said this was the first time it's publicly disclosed disciplinary actions against users and comes as the proliferation of prediction markets has raised concerns about users making trades using inside information and manipulating markets.

For more, I'm joined now by Journal reporter Crystal Herr.

Crystal, how did Kalshi catch these two users?

What rules did the users violate exactly?

And we should note that a spokesperson for the company that oversees Mr. Beast's business ventures said the firm prohibits its employees from making prediction market wagers using proprietary company information.

And it declined to comment on whether the employee still works there.
