The Oregon Lottery Commission made DraftKings the official partner for its mobile betting program, switching from rival Scoreboard.
Oregon allows only one sports betting operator, unlike other states which open up both in-person and mobile betting operations to several companies.
“There are a number of business benefits in terms of simplifying some of the structure and there are player benefits as the experience will be improved on the new platform,” Oregon Lottery executive director Barry Pack said Friday.
Meanwhile, Arizona announced Friday that pending regulatory approval, the state will become the 44th state to offer DraftKings Daily Fantasy Sports on Saturday.
"There is no better time of the year to launch our leading daily fantasy sports app than ahead of the NFL season," said Matt Kalish, co-founder and president of DraftKings North America. "We're excited for the opportunity to provide Arizona sports fans with the thrill of having some skin-in-the-game as we head into what we expect to be the busiest time of the year for our company."
After Arizona approves DraftKings, the only states where daily fantasy sports betting is prohibited will be Alabama, Hawaii, Idaho, Iowa, Louisiana, Montana, Nevada and Washington state, according to Legal Sports Report.
DraftKings shares were rising 3% to $59.60 in afternoon trading on Friday. Year to date, the stock is up nearly 30% and about 50% over the past 12 months.
