Elon Musk says his social media platform, X, could introduce a monthly fee for all users, citing the need to cut down on bots.
"It's the only way I can think of to combat vast armies of bots," says Musk during a talk with Israeli Prime Minister Benjamin Netanyahu in Fremont, California.
This could be one of various changes the tech tycoon has made since taking over the site in October last year, when it was known as Twitter.
Since then, 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.
