Next, says CEO Jason Robins, it may mint millionaires off the fantasy gridiron, too. Robins thinks it will take "one more mega-round" of venture financing to bolster his Boston-based brainchild's operations, and that an IPO could come in as little as two years, in 2016.
"We have an international road map we're working on," he told TheStreet.
This year, DraftKings soared past its projections of $200 million in prize payouts as fantasy fans flocked to the site to test their luck against experts like Drew Dinkmeyer, a Florida man who used to work in finance until he pursued his dream to a $1 million payday this past Monday night. That's significant for DraftKings, since the company takes about 10% of prize payouts for the bulk of its revenue. At $300 million in prize payouts, that puts the company's 2014 revenue at about $30 million. With projections to hit $1 billion in payouts next year, Robins suggested the company could have $100 million in revenue at the end of 2015.
Robins' team is relatively small -- 121 employees -- and DraftKings has yet to reach profitability, he told TheStreet, since the company is focusing on growth. Already, DraftKings has paid its top $1 million prize to Dinkmeyer and nine other skilled online players; more typical top prizes stretch into the tens -- and occasionally hundreds -- of thousands of dollars.
The concept is simple, and familiar to season-long fantasy football players, who are far greater in number than weekly challenge players. Players pick a lineup and the site tracks and awards points based on their fantasy team members' individual accomplishments that week. With DraftKings and other weekly challenge sites, once the fantasy week ends, prizes are awarded.
Right now, DraftKings focuses primarily on U.S. sports -- not just the National Football League, but the National Basketball Association, Major League Baseball, even the Professional Golfers' Association -- but that U.S. focus will soon change, Robins said.
"International is one of the most compelling long-term opportunities for us," he said, adding that "going into the U.K. is going to be a lot simpler than going into India" because of language and other issues.
One of the site's next verticals will take a swing at fantasy challenges for mixed martial arts fighters.
Since its founding in 2011, DraftKings has added more than $76 million to its coffers to bolster growth -- including a $41 million August venture round. The next funding will likely go toward tackling challenges in payment processing and translation and customer service in new markets, as well as a renewed focus on regulatory issues in these places.
One place DraftKings is not worried about regulation is in the U.S., where the company is also planning to launch new fantasy challenges for other sports. Already, a 2007 court case in New Jersey created a valuable precedent for sites like DraftKings.
"Fantasy sports, at least today, is not considered sports betting," said Behnam Dayanim, a partner with law firm Paul Hastings who focuses on gaming issues. "This is a whole area of law that is evolving; this hasn't been extensively tested."
Still, the precedent that supports weekly and daily fantasy sports challenge sites like DraftKings is relatively simple: fantasy sports are currently classified as games of skill, not chance, and participants enter the games with fees -- not wagers -- to play.
Plus, Dayanim said, traditional brick-and-mortar casinos do not view sites like DraftKings as competitors -- in fact, many big Las Vegas gaming companies actually view relationships with fantasy challenge sites as synergistic.
Elsewhere, other companies are piling into weekly fantasy challenge sites. FanDuel took on $70 million in funding just one month after competitor DraftKings completed its venture round earlier this year. That deal had big-name investors buying in, including KKR (KKR) - Get Free Report and NBC Sports Ventures. Previous backers in FanDuel include the venture arm of Comcast (CMCSA) - Get Free Report .
TheStreet Ratings team rates KKR & CO LP as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:
"We rate KKR & CO LP (KKR) a BUY. This is driven by some important positives, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth and good cash flow from operations. We feel these strengths outweigh the fact that the company has had sub par growth in net income."
