Chris Carlson is an online-gambling entrepreneur who moved to Minnesota from New York to shake an addiction in 2005 and stayed. Now he has cashed his chips and sold his company to one of the state’s newest public companies for $8.1 million in cash and stock.

SharpLink Gaming, a company valued at about $45 million that seeks to be a big player in sports and other electronic gambling, has acquired most of the assets of Carlson’s privately held FourCubed. Carlson declined to specify how the pot was divided between him and the other principal owner of FourCubed.

As part of the deal, Carlson, 44, is now “vice president of conversions” at SharpLink.
