Comcast is on track to lose more than double the number of cable-TV cancellations it experienced in 2017 due to cord-cutting, predicted a Wall Street analyst.

“We now expect Comcast to lose 400,000 video subscribers in 2018 while video revenue falls 1.4%,” UBS analyst John Hodulik said in a note to clients. Hodulik raised his original estimate of 320,000 customer losses as the cable TV customer loss trends grow worse.

Comcast lost 150,000 video subscribers last year, despite company executives touting its X1 set-top box platform as a tool to increase customer satisfaction and reduce disconnects. The X1 appears to no longer be a factor preventing customers from dropping cable television in favor of online streaming services and apps. Hodulik doesn’t believe Comcast is losing video customers to its traditional competitors either, because he predicts video subscriber losses will also grow at AT&T and Verizon.

Hodulik also forecasts a 67% increase in subscribers to services like Hulu, Netflix, and streaming platforms like DirecTV Now to 9.2 million in 2018, up from 5.5 million last year. By 2020, he predicts streaming services will have 15 million subscribers and 16% of the pay television market. As video losses mount, he predicts companies like Comcast will accelerate rate hikes on broadband service to make up for the revenue shortfall. There is little competitive pressure not to increase broadband prices further.
