Vince McMahon pocketed over $400 million in an instant on Monday ... selling a chunk of his TKO stock following his departure from the company over sexual assault allegations, according to a recent SEC filing.
McMahon dumped 5,350,000 shares -- about 25% of his stock -- while still holding on to his remaining stake in WWE and UFC's parent company, which is around 15 million shares.
The SEC filing notes the value of the stocks at $411.95 million ... though they could be worth closer to $436 million, as yesterday's TKO stock price closed at $81.
