(CNN)– Tickets for Barack Obama’s Democratic National Convention speech at the Invesco Field in Denver sold out within 24 hours, according to campaign officials.
In early July, convention organizers announced the Illinois senator would officially accept the Democratic nomination at the 75,000 seat stadium rather than a 20,000 seat hall.
According to the Colorado Campaign for Change, the application process closed Thursday afternoon after more than 60,000 seats were snatched up.
Due to unprecedented demand, the campaign has created a waitlist for Coloradans hoping to get a chance to attend the August 28 event.
Obama's largest event to date was in Portland, Oregon, in May, where he drew an estimated crowd of approximately 75,000. He has done at least one previous stadium event, a joint appearance with talk show host Oprah Winfrey at Williams-Brice Stadium in South Carolina that drew about 29,000 people.
John F. Kennedy accepted the Democratic nomination for president in 1960 at Memorial Coliseum in Los Angeles, a 92,500-seat stadium in which an estimated 80,000 people gathered for his speech.
