Shares of Twitter gained nearly 3.5% in late-morning trading hours Tuesday after billionaire investor Mark Cuban said that he started buying the social media platform’s stock as an artificial intelligence play.

In an interview on CNBC’s “Squawk Alley,” Cuban said he has been investing in companies that work in artificial intelligence, deep learning, and machine learning. The “Shark Tank” star said he started buying Twitter because “they finally got their act together” with AI.

The news comes just a day after Twitter saw a nice pop thanks to a massive insider buy from CEO Jack Dorsey. Last Friday afternoon, Dorsey tweeted that he purchased $9.5 million worth of Twitter stock (also read: Here's Why Twitter Stock Soared, May 1).

Monday’s move was also inspired by Twitter’s new partnership with Bloomberg. The micro-blogging site will be joining forces with the financial news outlet to provide 24/7 exclusive content. Twitter will start live-streaming Bloomberg-backed content this fall.

Shares of TWTR are now up more than 25% since the company reported better-than-expected first-quarter earnings and revenue figures last week. Twitter significantly outpaced estimates, adding about 9 million monthly active users in the quarter.
