AMC+, which costs $8.99 a month for a subscription, does not run ads.
They're really killing their golden goose by trying to launch all these streaming services rather than agreeing to some sort of profit-sharing agreement with Netflix like they were doing when it first came out. These movies have no value to anybody if nobody's paying to watch them and if every studio hides them behind yet another $10/month streaming service that nobody is signing up for, they're going to go bankrupt. Streaming is how we consume entertainment now, and that's not changing - but every movie studio launching their own streaming service would be like every movie studio lanuching their own video rental company in the 90's.
