Shares of Trump Media, the owner of social networking site Truth Social, jumped 5% at the opening bell Friday after the first U.S. presidential debate, with some investors believing it could become a bigger mouthpiece for the former president if he is re-elected.

President Joe Biden and former President Donald Trump clashed Thursday evening on topics including abortion, immigration and the Jan. 6, 2021 attack on the U.S. Capitol.

Biden's performance was largely seen as uneven, particularly early on. He tried repeatedly to confront Trump, who countered Biden’s criticism by leaning into falsehoods about the economy, illegal immigration and his role in the Jan. 6 insurrection.

In political futures markets, where investors can put money on the political fates of candidates, Biden’s odds of remaining the Democratic party’s nominee slid 29% after the debate.

Citi analysts said Friday there may be increased interest in Trump Media & Technology based on news headlines following the debate.
