To know for sure? Not really unless they themselves announce it. Right now the announcement comes from a third party CNBC reporter, so it's not official and there's plenty of room to claim a misunderstanding. But there are ways to gain some insight based on how hard GME is to borrow and the shorting interest, and that hasn't changed much from yesterday. If Melvin did manage to get out of their short, they handed that short to another party almost share for share, or they found a way to hedge their position. At any rate, GME remains the most shorted stock on the market, which means another short squeeze is possible. This Friday when options expire is going to be an absolute circus.
