Avengers 4: Every Character Confirmed So Far

Confirmed By: Infinity War

Though Chris Hemsworth has been one of the few actors not to talk about his involvement, the end of Infinity War confirms that he's involved in the sequel.

Thor has unfinished business, just as the other survivors do, and we can expect him to at least partly set up the resolution of the Asgard story when the survivors of his people resettle on Earth.

Before that, it's likely that Stormbreaker will taste Thanos' flesh again.
