A long-awaited sports betting lounge that opened on the western edge of the XL Center in downtown Hartford could end the fiscal year in June with a deficit as high as $750,000.

The 5,000-square-foot sports bar and betting venue off Ann Uccello Street, part of a $15 million package of upgrades to the XL Center, opened its doors Sept. 9.

It has since run a $284,100 deficit through December, which, according to Capital Region Development Authority Chief Financial Officer Joseph Geremia, puts it on course for a $600,000 to $750,000 deficit by the close of the fiscal year.

Geremia delivered his forecast during a Thursday afternoon board meeting of the CRDA, an economic development agency that, among other tasks, has oversight over the city’s sports and entertainment arena.
