Hamilton, the first black to drive on the F1 circuit, won the Canadian Grand Prix at Montreal June 10 and the U.S. Grand Prix at Indianapolis June 17.
Alonso, the defending F1 points champion, spent much of Thursday's pre-race news conference tying to explain he wasn't unhappy with sponsor McLaren.
Hamilton is the points leader going into Sunday's race with a 10-point edge on Alonso.
Hamilton's victory at Montreal made him the first rookie to win a Formula One race since Juan Montoya captured the Italian Grand Prix in 2001.
Raikkonen downplayed rumors of the return of former points champion Michael Schumacher, who retired last season.
"I haven't read any magazines for a long time, so I don't know anything about it," Raikkonen said. "I'm in a pretty safe place."
