Casino operator Wynn Resorts saw its shares soar to $69.91 at the close in New York last week after its founder, Steve Wynn, bought over one million of the company’s shares on the open market.

A filing with Nasdaq suggested Wynn shelled out an estimated $63.9 million for the 1,003,977 shares worth between $62.41 per share and $64.44 per share. The purchase was made between Dec. 4 and Dec. 8.

Wynn is already indirectly holding stake amounting to 10,026,708 shares through the Wynn Family Ltd. Partnership. With this new purchase, he now owns—directly and indirectly—11,070,000 shares, according to a press release from Wynn Resorts.

Wynn’s personal holdings is about 11 percent of the total, but the man has a limited ability to sell his shares due to an agreement with his ex-wife Elaine Wynn, Bloomberg reported.
