Bahaa Hariri is a Lebanese billionaire businessman and the eldest son of the late Lebanese Prime Minister and tycoon Rafic Hariri. His family’s immense wealth originated from Saudi Oger, one of the largest construction companies in the Middle East. Bahaa’s upbringing was privileged and international, marked by the high-stakes world of Middle Eastern business and politics.

He received a world-class education in the United States, graduating from Boston University. This financial and managerial training prepared him to be the first in his generation to take a leadership role in the family's diversified business interests, setting the stage for his career in large-scale real estate development and private investment, distinct from his late father's core construction business.

Bahaa Hariri’s career is defined by his focus on large-scale real estate development and his eventual decision to distance himself from the family's collapsing construction business, Saudi Oger. In March 2008, he left the family-owned Saudi Oger to concentrate entirely on his own property business, Horizon Development. This was a key strategic move, insulating his fortune from the severe financial difficulties that later plagued Saudi Oger.

His primary venture has been a $5 billion master-planned development in the Jordanian port city of Aqaba, known as Aqaba Development Corporation (ADC), aimed at transforming the area into a major commercial and tourist hub on the Red Sea. Bahaa manages his real estate and private banking interests from his base in Geneva, Switzerland. While his younger brother, Saad Hariri, entered and exited Lebanese politics, Bahaa has focused on strategic, long-term development projects and has, at times, expressed interest in reviving the family's political legacy in Lebanon.

Bahaa Hariri's social impact is deeply tied to the economic development and infrastructure of the Middle East. His multi-billion dollar project in Aqaba, Jordan, is designed to transform the region's economy, creating thousands of jobs and establishing a major port and tourist destination.

He supports various cultural and social causes, particularly in Lebanon, where he seeks to uphold his late father’s legacy of national investment and nation-building. His philanthropy focuses on education and community empowerment, channeling resources to support the nation's stability and future development.

Bahaa Hariri projects the sophisticated, high-net-worth style of a global investor and real estate developer. His attire is consistently elegant and formal, favoring custom-tailored European suits, reflecting his base in Geneva and his involvement in high-level international deals. His aesthetic is one of reserved confidence and financial authority.

His lifestyle is centered in Geneva, Switzerland, a hub for private banking, and involves extensive travel to monitor his massive real estate projects in the Middle East. His luxury is the security and stability provided by his vast liquid wealth, allowing him the freedom to engage in strategic, generational projects that define the future of regional urban development.
