Seller agrees to sell ticket at PRICE. Monopoly intermediate provider sells it at $PRICE+$markup. Monopoly intermediate provider sells it to a reseller, which artificially limits the supply available to buyers at any given moment. Buyers have to go to resellers, who then pay $markup2 back to the monopoly provider to transfer the ticket to the ultimate buyer. This may even repeat several times, resulting in the monopoly provider reaping more in markup fees than the seller receives for the actual product.
