NFL senior VP Brendon Plack sent a letter to CFTC Chairman Michael Selig recommending tighter regulation of sports prediction markets.
NFL seeks to ban easily manipulable contracts, "knowable in advance" events, and broadcaster "mentions" wagers, and to raise participant age to 21.
NFL recommends NFA partner with state gambling regulators and platforms sign agreements with bodies to block league employees and ban margin trading.
The recommendations come as CFTC is already in a rulemaking process on prediction markets, potentially influencing future U.S. regulatory framework.
