The Public Investment Fund (PIF) is the sovereign wealth fund of the Kingdom of Saudi Arabia, meaning it is owned entirely by the Saudi state and functions as a primary engine for the country's economic transformation and diversification under Vision 2030. Governed by a board of directors chaired by Crown Prince Mohammed bin Salman, the fund manages trillions of dollars in domestic and international assets, investing strategically across global technology, infrastructure, sports, and energy sectors to reduce the kingdom's historical reliance on petroleum revenues.
