These sites are really at odds with teams who have chosen the leasing vs. ownership of tickets, where leasees can only transfer and sell their tickets on the officially-sponsored marketplace.<p>I&#x27;m a season ticket holder for such a team, but can&#x27;t go to all the games, so I list quite a few each year, and I really hate that demand for tickets gets unequally spread through the official market and these other markets.<p>Is there a legal reason why a seat aggregator like SeatGeek doesn&#x27;t list these official site tickets? Is it just because they don&#x27;t get a kickback from them? Some other reason?
