The singer-turned UFO investigator spoke after being named UFO "Researcher Of The Year" by the International UFO Congress.
In his acceptance speech he suggested there was about to be a big leap in the quest for truth over aliens.
He has been involved in a mystery project, details of which emerged when emails he sent Hillary Clinton's campaign manager John Podesta were released by WikiLeaks during the US presidential election campaign.
The emails suggested he was in talks with significant US military sources.
DeLonge has previously made wild claims, including that he has met aliens near top-secret military base Area 51.
