Yes, Macau casino mogul Adelson.
Actually apparently he's transferred most of his wealth to his younger wife, and purportedly she calls most of the shots.
Yeah, the sale was reported earlier. But back in August the Trump Admin said a deal would be concluded in the next couple of months, when it had already been sold in July. However, the buyer hadn't been disclosed. Since it was clearly overtly political and sketchy. Bibi owes much of his long 2nd act in Israeli politics to Adelson. Bibi and Trump both intertwined with Adelson.
Fwiw, I went into Adelson's Macau casino once a few decades back. There were what looked like 15 year old prostitutes blatantly operating with the casino. Running a casino in Macau was a real shady gold mine back then, before the big int'l casino players moved in and the Chinese gov't took over. It used to be that CH gov't officials would go there and gamble with either gov't money or hugely corrupt wealth they had skimmed, until they learned Beijing was given access to all cctv footage. A few major jail sentences later, they shifted their gambling to more distant, discreet locales.
