Mohammed bin Salman, or MBS as everyone calls him, is currently 40 years old. He was born on August 31, 1985. In a region where leaders often rule well into their 80s, his age isn't just a number. It is a massive political statement.
Honestly, it’s kinda wild when you think about the timeline. Most people his age are just hitting their stride in middle management. Meanwhile, he’s been the de facto ruler of one of the world's most influential energy powers for years. He was only 29 when he became the world's youngest defense minister in 2015. Two years later, at 31, he was named Crown Prince. Now, in early 2026, he’s navigated nearly a decade of high-stakes global diplomacy, internal purges, and massive economic shifts.
The Millennial Prince
If you’re wondering how old is MBS because he looks younger than the typical world leader, you’re right. He’s a millennial. He grew up with the internet, social media, and a front-row seat to the rapid modernization of Riyadh. This isn't just trivia; it’s the engine behind "Vision 2030."
He graduated from King Saud University with a degree in law. He didn't go the route of many other Saudi royals who studied at Sandhurst or Ivy League schools. He stayed local. That "homegrown" education is something his supporters point to as proof that he understands the Saudi youth better than the "Westernized" elite. About 60% of the Saudi population is under 30. To them, a 40-year-old leader feels like one of their own compared to the octogenarians of the past.

Why the world cares about his age
Politics in the Gulf used to be a game of "gerontocracy." Basically, power moved horizontally among brothers, all sons of the founding King Abdulaziz. That changed with MBS. His father, King Salman, bypassed dozens of older cousins and uncles to put his son in the driver's seat.
This creates a unique situation. Since he is only 40, Mohammed bin Salman could realistically rule Saudi Arabia for the next 40 or 50 years. Stability? Maybe. Predictability? Not exactly. Most Western leaders—think Joe Biden or various European prime ministers—work on four-to-eight-year cycles. MBS is playing a game that spans half a century.
How Old is MBS and How Did He Get This Powerful So Fast?
The "how" is just as interesting as the "how old." His rise was a literal lightning strike in the world of Saudi politics.

- Vision 2030: In 2016, he launched a plan to wean the country off oil. People laughed at first. They aren't laughing now.
- The Ritz-Carlton Purge: In 2017, he rounded up hundreds of princes and businessmen. He called it an anti-corruption drive. Critics called it a power grab. Either way, it worked to consolidate his control.
- Prime Minister Status: In 2022, his father officially named him Prime Minister, further cementing his legal authority to run the government day-to-day.
Balancing Act: Reforms vs. Reputation
Being a young leader comes with baggage. He’s been the face of massive social changes: women driving, cinemas opening, and the curbing of the religious police. These were things people thought would take decades. He did them in months.
But there’s the flip side. The war in Yemen, the Jamal Khashoggi murder in 2018, and the crackdown on dissent. To many in the West, his age represents a certain impulsiveness or a "move fast and break things" tech-CEO energy applied to a sovereign nation.
What’s next for the 40-year-old leader?
As we move through 2026, the focus is entirely on the 2030 deadline for his massive transformation projects. We’re talking about NEOM—that futuristic city in the desert—and a total overhaul of how Saudis live and work.

If you’re keeping track of how old is MBS, remember that he’s essentially just started. Most leaders are finishing their legacy at his age. He’s still building his. For anyone following global energy, Middle Eastern stability, or even the future of professional sports (given Saudi Arabia’s massive investments in golf and soccer), this 40-year-old is the person to watch.
