Chicago Olympic organizers are on track to spend about $58 million trying to lure the 2016 Summer Games to the Midwest.

According to the group's Internal Revenue Service filing released yesterday, the Chicago 2016 Exploratory Committee spent about $9 million during the initial phase of the bid. It has previously estimated it would spend another $49 million before the International Olympic Committee picks a host city next year.

Organizers have said the bid will be privately financed and that they raised about $32 million between July 2006 and June 2007, the period covered by the recent filing. They ended that period with more than $22 million in cash on hand.

The tax-exempt group says it's on track to have the money it needs.

"Our fundraising for the last year has continued to be robust," Chicago 2016 spokesman Patrick Sandusky said. He would not provide more updated financial figures.

Along with Chicago, the others vying are Rio de Janeiro, Brazil; Tokyo; Madrid, Spain; Doha, Qatar; Prague, Czech Republic, and Baku, Azerbaijan.
