NEW YORK — Some investors aren’t waiting to see if former President Donald Trump’s plans for a media company to challenge the likes of Facebook, Twitter and even Disney can actually become reality — they’re all in.

Trump said Wednesday that he’s launching Trump Media & Technology Group as a rival to the Big Tech companies that have shut him out and denied him the megaphone that was paramount to his national rise. The announcement came nine months after Trump was expelled from social media for his role in inciting the Jan. 6 Capitol insurrection.

The new venture said it had been created through a merger with Digital World Acquisition Corp., and seeks to become a publicly listed company. Shares of Digital World Acquisition quadrupled in value in afternoon trading Thursday, even though there’s a long way to go before the deal gets finalized and the venture becomes a bona fide media outlet.

An earlier effort to launch a blog on his existing website was abandoned after the page drew dismal views.
