MGM Resorts International, which owns the Mandalay Bay hotel from where the gunman opened fire, was down 5%. Melco Resorts & Entertainment Ltd, Wynn Resorts Ltd and Las Vegas Sands Corp each fell 1 to 2%.
MGM Resorts said via Twitter that it had locked down hotels in the vicinity at the request of law enforcement officers. It was unclear if other casinos were also put on lockdown after the incident.
“Our thoughts and prayers are with the victims of last night’s tragic events. We’re grateful for the immediate actions of our first responders,” MGM Resorts stated.
Las Vegas’s casinos, nightclubs and shopping attract 3.5 million visitors from around the world each year.
