Facebook's (FB) - Get Report photo sharing app Instagram has now reached 250 million daily active users, the social media giant told CNBC on Tuesday.

The figure represents a 50 million user increase from April.

Instagram's now 250 million daily active users outpaces that of rival Snap Inc. (SNAP) - Get Report , whose flagship social media app Snapchat boasts 166 million daily active users.

Facebook, who once tried to purchase Snap, has been mounting an attack on the platform using Instagram.

In August of last year, Facebook revealed the "Stories" feature for Instagram, a feature considered to be the staple of Snapchat. 

Shares of Facebook fell 0.2% to $152.61 early Tuesday afternoon. Shares of Snap were sinking 3% to $17.35.

What's Hot On TheStreet

Amazon has some work to do with Whole Foods: Organic grocer Whole Foods (WFM) needs Amazon's (AMZN) - Get Report tech know-how, and it needs it very quickly to slash prices.

TheStreet's Lindsay Rittenhousewent shopping online at Ohio stores to see how Whole Foods stacked up against Walmart Stores Inc. (WMT) - Get Report and rival grocer Kroger (KR) - Get Report . While the results may not be shocking, they show just how much Amazon will have to cut for Whole Foods to be on equal footing with some of its competitors.

The cost of eight everyday food items at Whole Foods, TheStreet found, were nearly double those of the ones at Walmart, but Kroger undercut them both. Whole Foods' basket cost $38.29; Walmart's, $19.86; and Kroger's, $16.58.

With data as shocking as this, it's no wonder Whole Foods founder John Mackey is in love with Amazon.

Tesla's stock is out of control: Tesla Inc. (TSLA) - Get Report shares are expected to have a strong session amid reports Elon Musk's electric car baby may open a new production facility in China. Such a move would avoid tariffs in the world's second-largest economy, but risk the ire of U.S. President Donald Trump's "buy American, hire American" industrial policy, TheStreet's Martin Baccardax reports.

Tesla's market cap is now more than $60 billion and climbing, despite the company continuing to lose money. Ford's (F) - Get Report market clocks in at $44.7 billion, while General Motors (GM) - Get Report stands at $51.9 billion.
