How do foreign investors respond to domestic electoral politics? A political investment cycle dynamic predicts investments increase before elections while an uncertainty and delay hypothesis anticipates investment declines in advance of elections. This study adjudicates these competing expectations, arguing that foreign firms locate their investments based, in part, on electoral predictability. We theorize that firms prefer to invest in locations holding clear-winner elections, and avoid close-call elections, where the outcome is uncertain. We test this theory in the context of U.S. congressional elections, arguing that legislators provide access to public resources, policy influence, and coordination across levels of government, and therefore investors benefit from stable representation. Using geolocated data on greenfield foreign direct investment (FDI) announcements in the United States from 2003 to 2017, we find that FDI announcements rise significantly in election years—but only in districts with clear-winner elections. Mediation analysis shows that increased federal appropriations partly explain this pattern, consistent with our argument that electoral predictability enhances firms’ ability to secure political support. These findings reveal a political bias in global capital allocation: politically monopolistic districts attract more investment, while vibrant electoral competition deters it—raising fundamental concerns about the interplay between democracy and money.
