Adds annual forecast in paragraph 4

July 29 (Reuters) - U.S. sports-betting service BetMGM, a joint venture between Entain ENT.L and MGM Resorts MGM.N, has raised its full-year 2025 revenue and core earnings forecast after posting a 35% rise in first-half revenue, helped by strong demand in online sports betting and its iGaming division.

Growth in player volumes and engagement helped lift iGaming revenue by 28% in the first half, Entain said.

Founded in 2018, BetMGM has been expanding its digital footprint to tap into the fast-growing U.S. e-betting market amid stiff competition.

BetMGM now expects revenue of at least $2.7 billion and core earnings of at least $150 million in fiscal year 2025, Entain said.

It had earlier forecast revenue of at least $2.6 billion, and earnings before interest, taxes, depreciation, and amortization of at least $100 million.
