Where did the shares come from? Market Maker inventory.

"A market maker is a broker-dealer firm that assumes the risk of holding a certain number of shares of a particular security in order to facilitate the trading of that security. Each market maker competes for customer order flow by displaying buy and sell quotations for a guaranteed number of shares, and once an order is received from a buyer, the market maker immediately sells from its own inventory or seeks an offsetting order."
