Saudi Arabia has suspended the planned construction of a giant dome-shaped skyscraper at the center of an urban development in Riyadh while it reviews the project's financing and feasibility, Reuters reported, citing four sources familiar with the matter.
Mukaab, at the heart of the new New Murabba development in Riyadh, is the latest project linked to Saudi Arabia's Vision 2030 to be curtailed or postponed as the kingdom's $925 billion sovereign wealth fund scales back ambitions to manage costs and prioritize spending.
The kingdom is moving away from heavy spending on futuristic projects that have dominated Crown Prince Mohammed bin Salman's vision, such as NEOM's The Line, toward initiatives considered more urgent and potentially more profitable.

Projects that are now in focus include infrastructure for the 2030 World Expo and the 2034 World Cup, the $60 billion Diriyah mixed cultural zone, and the Qiddiya tourism megaproject.
This repositioning also reflects growing fiscal pressures, as oil prices remain well below the levels needed to finance the ambitious transformation agenda.
Works beyond excavation of the soil and foundations have been suspended.
Mukaab was planned as a 400-meter by 400-meter metal cube, containing an artificial intelligence-powered display dome (the largest on the planet) that visitors could view from a structure over 300 meters high.

“When you enter Mukaab, you enter a different world,” CEO Michael Dyke said at a conference in Riyadh in December, acknowledging the challenges of bringing the project to fruition. “Trying to solve something that doesn’t exist today is quite challenging,” he added.
The future of the project is now uncertain, with work beyond excavation and foundations on hold. Development of surrounding real estate is expected to continue, according to five people familiar with the plans.
