Casino operator Caesars Entertainment has struck an online casino and sports betting partnership with DraftKings that will include Caesars taking an equity stake in DraftKings.

On Monday, Caesars announced the company’s first “multi-state partnership” that will see Caesars offer DraftKings’ “market access for its online gambling products,” subject to local legislation and licensing regimes. The deal calls for DraftKings to promote Caesars as its “official casino resort partner” in the states where the companies collaborate.

DraftKings’ market access is “exclusive to Caesars across certain states in which Caesars operates casino properties,” while Caesars will retain the right to offer its own branded sports betting and online gambling products in the jurisdictions in which the casino operator does business.

Caesars will also take an undisclosed equity stake in DraftKings and Bloomberg reported that Caesars will receive a share of DraftKings’ revenue in states in which both parties operate.
