Musk planned tocut about 3,700 jobs at Twitteror about half of its workforce, Bloomberg reported on Wednesday.
The move came after Musk completed a deal to buy Twitter for $44 billion and fired several executives.
Musk tried to back out of the deal, but Twitter sued him to enforce the agreement.
The company has 238 million daily users on its platform who can see ads.
Other ideas involve ways to make money outside of advertising.
