Earlier in 2021, FTSE-listed Entain rejected an all-stock offer from MGM Resorts in a deal that would have been worth $11bn.
The company, which owns Ladbrokes and Coral, could jeopardise a joint-venture with MGM, called BetMGM, to offer sports betting in the US if the bid by DraftKings is accepted.
Entain stock jumped 17.6% in afternoon trade in London, increasing the share price by 327.5p to trade at 2,245p.
Meanwhile, DraftKings stock told a different story, slumping 6.8% in morning trade in the US.
The deal was confirmed in a filing to the London Stock exchange, however the document didn't contain details of the proposed offer.

“A further announcement will be made as and when appropriate,” Entain siaid. “Shareholders are urged to take no action at this time."
DraftKings has been riding a pandemic gambling boom over the last year and a half. Its listing via a SPAC deal in April 2020 has seen its market value rise more than sixfold from its $3.3bn valuation since.
