McCormick Place has 2.6 million SF of exhibit space, but that's not including who knows how much back of house and logistics space. But, like the Pentagon or FCA HQ, it's a complex, not a single building.
The Sears Tower is still the "biggest" single building on Earth even if it's not the tallest anymore. It's simply gargantuan and there probably will never be a need to build anything on its scale ever again. Any other supertalls that approach it's SF only do so due to large malls attached to their base, again making them complexes, not single stand alone structures.
