The company has doubled its brand portfolio to 20 in the past decade, and has in excess of 6700 properties in more than 100 countries.

“Reaching one million rooms reflects the deep trust and confidence our guests, owners and investors place in IHG and our brands,” says Elie Maalouf, CEO of IHG Hotels & Resorts.

“But more than that, it’s a celebration of our colleagues, who help millions of guests live their best lives every single day – be it with a warm welcome the minute they walk through our doors or helping make memories in life’s big events.

“We’re all excited about the many more special moments our hotels will be part of in the years ahead.

“With a strong, growing development pipeline spanning world famous brands, beloved heritage and rapidly growing new brands, the future is bright for IHG.”

IHG opened a record number of rooms in the first half of 2025 and has celebrated several key achievements in the past year, including reaching 4000 open hotels in the US, and its 800th open hotel in Greater China.

The company has a further 2200 hotels in its development pipeline.
