A company led by Barry Diller has made an offer to buy MGM Resorts International, but one Wall Street analyst suggested it remains unclear if the Las Vegas operator would accept the deal. Diller’s People Inc., previously known as IAC, is making the offer, the company said in a statement released this morning.

The move follows news last week of companies controlled by billionaire Tilman Fertitta acquiring Caesars Entertainment. The New York Times reported it’s “unclear whether a bid by People Inc. for MGM Resorts would put the casino operator in play, drawing in other suitors.
