According to this source: This content is protected Interestingly, I had seen other sources before this article quote a similar number in English, and there are multiple Japanese articles suggesting this sum. According to the article, Inoue is guaranteed a little over 4.5 million USD and is expected to earn about 5.7 million USD (800 million yen) after his PPV share. His highest total pay to this point was about 2.3 million USD vs Butler, and according to this source, his highest pay before that was in total about 1.6 million USD (230 million yen) vs Donaire in the rematch. If the Fulton figure is anywhere near true, Inoue is really becoming a breakout cash cow for the lower weight classes. Fulton meanwhile is supposedly guaranteed 380 million yen, which is about 2.7 million, and an unspecified amount of PPV will be added to that, I would imagine to the tune of 800k USD (based on 60-40 split) bringing Fulton's total purse to about 3.5 million USD if the PPV sales prediction is accurate, which is also absolutely gigantic for the weight class.
