Barry Diller’s $18 Billion MGM Bid Could Reshape BetMGM and the Entire US Online Sports Betting Market

Barry Diller’s People Inc. submitted a $48.30 per share cash offer on June 2 to acquire all outstanding shares of MGM Resorts International it does not already own, proposing a transaction that would value the casino giant at approximately $18 billion and could fundamentally reshape the US online sports betting market. People Inc., which already holds a 26.1% stake in MGM Resorts and was formerly known as IAC, indicated it would seek to own just over 50.1% of the combined company, with existing MGM shareholders retaining minority interests. MGM’s board of directors has confirmed receipt of the proposal and said it will carefully review the offer.

The most significant downstream implication for the sports betting industry centers on BetMGM, MGM’s online sports betting and casino joint venture. BetMGM is co-owned equally by MGM Resorts and Entain, the UK-listed gambling company that also owns brands including Ladbrokes and Coral. Analysts at BNP Paribas have noted that while the People Inc. bid does not directly suggest immediate interest in Entain’s stake, a change of ownership at MGM could accelerate management ambitions to fully consolidate BetMGM. If People Inc. completes the acquisition and then moves to buy out Entain’s 50% stake, the resulting fully owned BetMGM would be one of the most significant structural changes in the US legal sports betting market since legalization.

BetMGM’s Market Position

BetMGM is currently one of the three largest online sportsbooks in the United States, operating in more than two dozen legal states alongside market leaders FanDuel and DraftKings. The platform has historically competed on the strength of MGM’s loyalty program integration, its Bellagio and Aria property tie-ins, and a range of sports betting and online casino products. A fully consolidated BetMGM under sole MGM ownership would remove the need for joint venture governance and could allow for faster product development and more aggressive promotional investment. However, any such transaction would first require the People Inc. bid to be accepted by MGM’s board, which has not signaled its intentions as of early June.

The MGM proposal follows Fertitta Entertainment’s definitive agreement to acquire Caesars Entertainment for $17.6 billion, announced just days earlier. Wall Street analysts have described the back-to-back bids as the opening salvos in what could be a broader privatization wave across the US casino industry. Truist Financial analyst Barry Jonas noted the Caesars deal represented a needed catalyst for incremental M&A activity and said the People Inc. bid reinforces that view. The Caesars transaction includes a go-shop window through July 11 where alternative offers can be considered, adding further potential movement to an already active deal environment. Sports bettors using BetMGM or Caesars Sportsbook should expect their platforms to continue normal operations throughout any ownership transition process, which typically takes many months to complete.

What Happens Next

MGM’s board has given no public indication of how it intends to respond to the People Inc. offer. The company’s management has previously characterized MGM’s shares as materially undervalued, which could make acceptance of the bid politically difficult even as shareholders assess the 10.6% premium to the recent closing price. Wall Street has responded positively to the offer; MGM stock surged following the announcement. The company faces a complex decision given its long-term growth assets in Japan and Macau, which extend beyond most investors’ typical time horizons and may not be fully reflected in the proposed bid price. BetMGM and BetMGM promotions remain available to players across all markets while the deal process plays out.
