Global entertainment company MGM Resorts International will be added to the S&P 500 index, effective prior to the open of trading on July 26.

"We are honoured to join the esteemed companies that comprise the S&P 500 index," said Jim Murren, chairman and CEO of MGM Resorts.

"As with all of our company's accomplishments, this significant milestone represents the efforts of the 77,000 men and women dedicated to delivering the finest entertainment experiences at MGM Resorts and our continued commitment to maximise shareholder value."

The S&P 500 index is regarded by many as the best single gauge of large-cap US equities. MGM Resorts will be added to the GICS Casinos and Gaming Sub-Industry index.
