Online platform X, formerly Twitter, could introduce a monthly fee for all users, its owner Elon Musk said, citing the need to cut down on bots.
The tech tycoon has made multiple changes since taking over the site for $44 billion in October last year, when it was known as Twitter.
He has fired thousands of employees, introduced a paid premium option, cut content moderation and reinstated formerly banned accounts including that of former US president Donald Trump.
He said in July the platform had lost roughly half its advertising revenue.
