Facebook to buy Meerkat? One 'insider' says yes

Growth of the 'instant' economy: Angel

Facebook could make its way into the mobile live-streaming space very soon, Weblogs CEO Jason Calacanis said Friday.

"Meerkat is going to be bought by Facebook, I think, in the next six months," Calacanis told CNBC's "Squawk Alley."

"As you know, I have a lot of inside information," Calacanis said. "I'm not an investor in Meerkat, sadly, or, Periscope—I missed both of those—however, I do have a lot of inside information," he said, adding that he doesn't trade stocks.

However, in early March, Meerkat CEO Ben Rubin told CNBC's "Squawk Alley" he was not ready to sell his company just yet. "Our main focus right now is to continue to grow, and try to find more uses [for the app]," Rubin said. "Right now we're just focused on making something awesome"

Meerkat, a mobile live-streaming app, launched earlier this year at the South by Southwest Festival in Austin, Texas, and was an instant success. "Twenty percent of [users] watch a minimum of two hours a day, [while] 8 percent watch a minimum of three hours, and on top of that, 4 percent watch a minimum of four hours," Rubin told CNBC's "Squawk Alley" last month.

Nevertheless, Rubin's company saw Twitter quickly hop on the mobile live-streaming bandwagon when it launched Periscope, its own live-streaming app, on March 26.

Calacanis told CNBC months ago that Twitter would start accepting payments for verified accounts.
