"It turned out we were a soccer country, and I think it's going to remain," Trump said on Friday at a FIFA reception at Trump Tower in New York City.
"This has really brought the world together."
For the White House, Sunday's match was the culmination of well over a year of navigating a litany of logistical challenges alongside co-hosts Canada and Mexico for what would be the biggest World Cup in history.
It had to balance the Trump administration's hard-line migration policies that barred fans from some World Cup qualifier countries from entry into the United States.
Spain won the tournament with a 1-0 victory over defending champion Argentina.
After Trump and FIFA President Gianni Infantino presented them with the trophy, Trump stood alongside the team as they jumped up and down and gold confetti shot out of a cannon.
Later, speaking to reporters at Joint Base Andrews, Trump said he took pride in the country's success as a host, adding that "all over the world, people have come and they love our country".
He arrived at Sunday's final with a flyover in the presidential helicopter, Marine One. Before the game even kicked off, Trump was already proposing another US bid to host the tournament, sending a nudge to Infantino.
"I had a great idea for Gianni: You have to do two countries. Announce us again next time, and then announce another country after that. It'll take out some of the anger and the shock," Trump said on Fox Sports.
"Based on the numbers, we will be requesting it again immediately."
Trump created controversy with a phone call he made to Infantino earlier this month in which he asked for a review of a controversial referee call in Team USA's match against Bosnia and Herzegovina. The referee gave a red card to US star forward Folarin Balogun, meaning he wouldn't be able to play in the subsequent match against Belgium.
Trump says he simply asked Infantino, who has cosied up to the US president and faced backlash for doing so, to review the call, which FIFA then reversed.
The Trump administration was under considerable pressure to pull off a successful World Cup tournament because the US will soon host the 2028 Summer Olympics in Los Angeles and the 2034 Winter Olympics in Salt Lake City.
