Halloween Is the Second Most Commercial Holiday of The Year for the U.S. Of course, the number one most commercial holiday in America is Christmas. But right behind that comes Halloween, which rakes in billions of dollars each year. The candy industry makes billions of dollars each year because of Halloween, and Americans spend an estimated $6 billion a year on Halloween – that includes money spent on candy, costumes and decorations. That’s insane, but obviously so worth it because Halloween is awesome.
