Can the ultra-rich shape electoral results by controlling media outlets that openly propagate their political interests? How consumers discount slanted media coverage is a question gaining urgency as a growing number of billionaires mix ownership of major media outlets with business interests and political agendas. We study this question in the context of Israel, where billionaire Sheldon Adelson launched in 2007 Israel Hayom, a right-leaning newspaper. Handed out for free, it soon became the most widely read newspaper nationally. Utilizing local media exposure data since the launch, our analysis indicates that the newspaper exerted significant electoral influence, primarily benefiting Netanyahu and his Likud party. This shift helped bring about a sea-change in the right’s dominance of national politics. Our results highlight the immense impact the ultra-rich can exert in shaping politics through media ownership.
