PlayUp Limited announced today that it has entered into a partnership with BetSwap Limited that will allow its U.S. online sportsbooks access to innovative secondary market technology.

BetSwap allows users to buy and sell active bets with odds that are no longer available at sportsbooks. Terms of the agreement were not disclosed, though PlayUp Chief Strategic Officer Tony Caine said it should be operational by this weekend’s full slate of NFL games for the first week of the regular season.

“It’s a really unique way for our users to get social on our sportsbooks and potentially take advantage of a missed opportunity,” said Caine in a press release announcing the partnership.
