PlayUp, an Australian sportsbook operator, may think about leaving the US sports betting market as it struggles to find a buyer and has to fund money. PlayUp currently provides mobile sports betting in Colorado and New Jersey, reiterating its position as a minor player in the US sports betting market. A week after claiming to be close to a deal to sell its US business to an unnamed publicly traded company, word of the gambling company's probable exit from this nation breaks. The closing of that deal was anticipated to occur this quarter.
