UFC 68: "The Uprising" — the first-ever UFC event in Ohio — is the highest-grossing event at Nationwide Arena, topping popular draws such as the Rolling Stones and the combined effort of Billy Joel and Elton John, according to The Columbus Dispatch.

Naturally, UFC 68 is sold out, generating more than $2.8 million in ticket sales. In comparison, UFC 66 did about $5.4 million and UFC 57 raked in an estimated $3.3 million — the best gates on the books for the UFC to date.

Having said that, UFC 66 packed the MGM Grand Garden Arena in Las Vegas, Nevada, with 14,607 fans and spectators. In Columbus, UFC 68 could attract around 18,000 onlookers.

Of course, the difference in the gates can be attributed to the cost of tickets. According to the article, 16,000 fans paid between $100 and $400 in the first day of sales for seats. And as seats begin to disappear, the costs tend to go up.
