Other than SpaceX there's no one flying reusable rockets yet. If SpaceX did go bankrupt we'd have a big problem, since almost no one else still flies in the US or Europe at all. Partly that's because there's such a small demand for launches but it's also an industry with a huge technical barrier to entry. But for sure SpaceX hasn't led to a competitive market in space launch, it's just moved from one dominant player to another.
