Newsmax (NYSE:NMAX) went public on the New York Stock Exchange on Monday.
The conservative cable news network's audience has grown after the election of President Donald Trump and other right-wing politicians.
Newsmax stock opened at $14 a share and soared more than 700% in volatile trading.
The IPO comes at a time when traditional cable TV has suffered as consumers opt for streaming, and the demand for right-wing prime-time content has increased.
