It was a dangerous display of hubris for a broadcaster that is struggling to break free of its calamity-strewn image. Yet its newfound confidence is not completely without reason.
Positive signals are emerging from its Paddington HQ that point to some momentum behind its brand of opinionated news.
Flagship shows Farage, Brazier and Dewbs & Co are attracting a more consistent audience, helping GB News beat Sky News in some timeslots and battle the BBC in others.
It begs the question. After nursing zero viewers for some programmes shortly after launch, can Trump’s blockbuster billing help GB News capitalise on its green shoots of growth?
The ‘Trump bump’
There is no denying that Trump has a track record of creating the kind of headlines that haul in viewers to his unique brand of populist politics.
Such is the impact that news broadcasters across the Atlantic have struggled to maintain their appeal amid a quieter news cycle under President Joe Biden.
A tail-off of the Trump effect is credited with causing the primetime ratings of CNN, the US news network, to fall by 52pc in the third quarter for viewers aged 25 to 54, according to Nielsen data.
Meanwhile, left-leaning MSNBC fell 51pc, while Rupert Murdoch’s right-leaning Fox News proved more resilient with a decline of just 37pc for the period.
With Trump promising to extol his opinions on controversial topics such as the performance of Boris Johnson and the Sussexes, the opportunity for GB News to gain their own “Trump bump” looks possible.
Yet there is uncertainty as to whether Trump is still the kind of blockbuster draw that will transform GB News sceptics into dedicated viewers.
It is unlikely to harm the brighter performance enjoyed by GB News chief executive Angelos Frangopoulos.
Farage’s 7pm slot has maintained its appeal, with his ratings beating Sky News on five nights late last month.
