The 2011/12 Premier League champions will step into MLS as the 20th franchise in a partnership with Major League Baseball's New York Yankees to form New York City FC.
Beckham, who spent six years with LA Galaxy winning two MLS Cups, had a clause in his MLS contract allowing him to buy into a franchise but Soriano made it clear that New York City FC would not be it.
"We've never spoken to David Beckham and he's never been considered as part of the ownership of this team," Soriano said on a Tuesday media teleconference call. "Not even as an executive."
MLS Commissioner Don Garber also iterated the point that Beckham, who has now retired from playing, was never in the running to be part of a second team in New York.
"Anything's a possibility other than his right to exercise that option in New York," Garber said.
