Cuban has written a $40,000 check to the local group that puts on the parade. The Greenville Avenue Business Association had announced earlier this month that it would have to cancel the parade without more fundraising.
Cuban says he wanted to do the right thing and save a tradition he's enjoyed in the past. He's also donating to the business association's scholarship fund.
This year's parade is on St. Patrick's Day, Saturday, March 17.
