See it on the Geopolitics map →The picture
Born in 1985, MBS rose fast after his father became king in 2015: defense minister, crown prince in 2017, prime minister in 2022. His Vision 2030 plan aims to diversify beyond oil through tourism, giga-projects such as NEOM (since scaled back) and the Public Investment Fund. He loosened social rules, letting women drive, while jailing critics. US intelligence assessed that he approved the 2018 operation that killed journalist Jamal Khashoggi; he denies ordering it.
Why it matters
He controls the largest oil exporter, the custodian of Islam's holiest sites, and the decisive vote on whether more Arab states normalize with Israel.
Record
Royal decrees, Saudi budget and Public Investment Fund filings, the declassified February 2021 US intelligence report on Khashoggi, and records of his November 2025 White House visit.
What to watch
Whether Vision 2030 survives disrupted oil exports and the 2026 regional war, and whether he would recognize Israel without a credible path to a Palestinian state.

▸Mohammed bin Salman (MBS) is de facto ruler of Saudi ArabiaFact
The relationship
King Salman, born in 1935, remains head of state, but his son Mohammed runs the kingdom day to day as crown prince and prime minister. He controls defense, oil policy, the sovereign wealth fund and security services, having sidelined rival princes in the 2017 Ritz-Carlton anti-corruption detentions.
Since when and why
Riyadh; named crown prince in June 2017, replacing his cousin Mohammed bin Nayef, and prime minister in September 2022.
How we know
Royal decrees naming him to each post, and his chairing of the Council of Ministers and the Public Investment Fund.
What to watch
When he becomes king, how he would rule without his father's cover, and who would succeed him.
▸Mohammed bin Salman (MBS) steers oil policy in OPEC+Widely agreed
The relationship
As the largest exporter with the most spare capacity, Saudi Arabia co-leads OPEC+ with Russia, and MBS sets the strategy carried out by his half-brother, Energy Minister Prince Abdulaziz bin Salman. Riyadh led deep output cuts in 2022–23, then raised production from 2025 to win back market share.
Since when and why
OPEC+ meetings in Vienna and online. The UAE quit OPEC and OPEC+ on May 1, 2026, seeking freedom to pump more, a sign of strain with Riyadh.
How solid?
OPEC+ communiqués and production data from OPEC and the IEA; MBS's final say is widely reported by analysts but inferred, not published.
What to watch
How the group holds together after the UAE's exit, and whether Saudi priorities favor high prices or market share.
