Both push a building sideways. That's where the similarity ends — they come from opposite physical mechanisms, and codes treat them as separate hazards, not one combined event.
It's tempting to lump wind and seismic together under "lateral load" and assume the worst-case design just adds them up. But wind is a force the atmosphere applies to the outside of a building, and seismic is a force the building applies to itself as it resists being shaken. They scale with completely different properties — wind with exposed surface area, seismic with mass — and building codes evaluate them in separate load combinations, never both at their full design magnitude at the same time.
