Disney is projected to sign up 130 million subscribers by 2024, according to a Wall Street analyst.
That's almost double Netflix's projected 79 million subscribers by the same year.
The subscribers will, however, be spread across multiple streaming services including Disney+, ESPN+ and Hulu, which Disney has operational control of after agreeing to a deal with Comcast in May.
Disney+ is set to launch ahead of schedule starting in the U.S. in November.
Stocks in the Walt Disney Company leaped in response to the forecast.
