DraftKings was under investigation by Nevada Gaming Control Board to determine whether it was offering gambling or fantasy sports.  DraftKings’ position is that its platform is a skill contest, while other sites are “games of chance.” The company also has a “daily fantasy sports” category on its website.
In late September 2016, NFL best bets CEO Jason Robins said that he was in discussions with the NBA, MLB, and Major League Baseball Players Association about potentially creating a new type of basketball contest that would feature NBA teams competing against each other. 
“We’re in discussions with the NBA and its player’s union for possible partnerships,” Robins said. “We certainly hope to have more information on that in the next several months.”
About a week before the second NBA season game, DraftKings announced  a partnership with the league to become DraftKings’ “Official Daily Fantasy Partner of the NBA.” In addition to having its logo appear on selected in-game materials on national and local television broadcasts, DraftKings will receive the right to use NBA-related intellectual property advertisements.
DraftKings also announced a deal with Major League Baseball (MLB) for the 2016 and 2017 seasons. The partnership includes integrating DraftKings into MLB’s At Bat mobile application and sponsorship of live pregame shows on MLB Network. 
On Oct. 6, 2016, NFL best bets struck a deal to become the NBA’s official daily fantasy provider.  That day, while fewer than 500 people were playing in any of DraftKings’ NFL contests and Major League Soccer (MLS) was still in preseason, more than 2.7 million players entered a daily fantasy sports contest DraftKings. 
As of October 2016, at least eleven states had proposed legislation related to daily fantasy sports: Arizona, Arkansas, California, Hawaii, Idaho, Illinois, Indiana (two bills), Iowa (two accounts), Massachusetts, and Vermont.  [9 California (assembly bill AB-1934) would require operators to obtain a gambling license from the state. , 
According to ESPN, “Fantasy sports contests have been compared to online poker, and daily fantasy sites are now pushing for regulations similar to online poker’s Unlawful Internet Gambling Enforcement Act of 2006. That law prevents the Department of Justice from prosecuting companies that operate in states where online gambling is legal; it also blocks credit card companies and banks that service those illegal sites, effectively squeezing out those who profit from such gaming.” 
The Nevada Gaming Control Board began investigating whether DraftKings was offering gambling or fantasy sports.  In a letter to DraftKings, the board asked for an explanation of how daily fantasy sports contests work and information about its marketing practices in Nevada. The company has until Nov. 10 to respond, according to Richard McGarrah Lee, chairman of the board’s investigative arm.
Also, on Oct. 6, 2015, the New York Attorney General Eric Schneiderman sent cease and desist letters to DraftKings and FanDuel demanding they “immediately stop accepting bets from residents of New York.” 
“No matter how DraftKings tries to dress it up, ‘daily fantasy sports is gambling,” he said in a statement.
DraftKings is a business that offers daily fantasy sports. It’s one of the largest companies in this field and has been under much scrutiny for its legal status as gambling or skill-based contests. The NFL’s best bets are offered by DraftKings, which may be why they’re so popular with players who enjoy betting on football games.
The main selling point for NFL best bets is the ability to choose your players, as opposed to traditional season-long leagues, where you might draft or be assigned a team and can’t make any changes. The downside? Most daily fantasy sites require an entry fee, almost like gambling in Las Vegas. But unlike traditional season-long leagues.
