Twitter’s German-listed shares slumped as much as eight per cent on Monday, the first trading day after it permanently suspended US President Donald Trump’s account late on Friday.
The company said the suspension of Trump’s account, which had more than 88 million followers, was due to the risk of further violence, following the storming of the US Capitol on Wednesday..
At 1011 GMT, the social media firm’s US-listed shares were also off 6.8 per cent at $47.94 in thin premarket trading.
It was the first time Twitter banned a head of state, sparking a worldwide controversy over the impact US tech giants can have on free speech and democracy more broadly.
For Twitter’s balance sheet itself, the decision to ban the US president is expected to have a moderate negative impact.
“Expect slight user decline, though engagement erosion is a bigger question,” Berstein analysts wrote in a note looking into the issue.
Far-right groups maintain a vigorous online presence on digital platforms like Parler, Gab, MeWe, Zello and Telegram and could disengage from mainstream social media.
There could also be additional costs for Twitter and others as they seek to further moderate content uploaded by their users.
