Rybolovlev was the seller, the question is who is paying him and who did he buy it from for $127 million in the first place? At this high a price it seems more like money laundering than painting the tape, but who knows.
It says in the article that Dmitry Rybolovlev (his family's trust to be exact) bought it from Yves Bouvier for $127.5 million in 2013, which occurred soon after Bouvier had purchased it earlier in 2013 for $80 million in a private sale via Sotheby's.
