Update 12/17/22: Reddit user said that a phone rep said the fee is increasing to $650 in January.
Over the weekend a rumor was shared that American Express planned to increase the annual fee on the Hilton Aspire by $100 to $550 and include Centurion lounge access for the primary cardholder. After checking with some sources it seems extremely unlikely that this will be the case (although it’s possible the annual fee will be increased at some stage next year).
