According to a presentation to prospective Twitter investors seen by The New York Times (NYT), Elon Musk wants to more than fivefold Twitter’s revenue to $26.4 billion (£21.4 billion) by 2028.
Twitter made $5 billion in revenue last year.
The report also reveals plans to launch a new service called X, with a target of nine million subscribers in its first year and 104 million by 2028.
Tech industry analyst Kyle Rees says the goals are “very tentative given the state of global and industry affairs”.
The NYT says the revelations are in a “pitch deck” presented to investors “in recent days”.
It implies that Mr. Musk expects the number of Twitter users to increase from more than 200 million last year to more than 900 million by 2028.
The document also reveals that Twitter’s workforce will increase by 3,600 by 2025. However, according to the New York Times, the staff headcount is likely to fluctuate in the short term.
Mr Musk recently tweeted that employees should anticipate work ethic expectations that are “extreme, but much less than I demand of myself”.
According to the New York Times, advertising will account for roughly 90% of Twitter’s revenue in 2020.
Subscription services are expected to play a significant role in increasing Twitter’s revenue, which is expected to reach nearly $10 billion by 2028.
The document suggests that one source of that income will be an enigmatic new product called X, the details of which have yet to be revealed.
There is also a target of 69 million Twitter Blue subscribers by 2025, and 159 million by 2028.
Twitter Blue already exists, and for a $3 monthly subscription, users in countries where it is available get features like an undo tweet button and ad-free articles.
