Aldar Properties and Mubadala Investment Company have jointly acquired Masdar City Square for AED 918 million through their Masdar City-focused joint venture established in 2024. The acquired property is a completed seven-building Grade A office complex in Masdar City, Abu Dhabi. According to the 16 September 2026 announcement, it has more than 47,000 square metres of net leasable area and was 99% occupied at the time of the announcement.
The acquisition increases the joint venture’s stated Masdar City portfolio to AED 4.7 billion. The deal is an investment in an operating, income-generating commercial asset. It is not an announcement that Masdar City Square is a new project still awaiting construction.
What did Aldar and Mubadala acquire?
Masdar City Square is an office complex located within Masdar City, Abu Dhabi, near Zayed International Airport. The latest official announcement describes the asset as seven office buildings with more than 47,000 square metres of net leasable area. The buildings were completed in the first quarter of 2026 and were reported to be 99% occupied on 16 September 2026.
The announced tenant list for Masdar City Square includes TAQA, the Abu Dhabi Department of Energy, Emirates College, and Mohamed bin Zayed University of Artificial Intelligence. The announcement also identifies a net-zero-energy headquarters building occupied by the Department of Energy.
The property should be distinguished from the wider Masdar City ecosystem. Other organisations named in the announcement, including IRENA, Masdar, Siemens, G42 and the UAE Space Agency, are described in the context of the joint venture’s broader Masdar City portfolio. The official release does not establish that all of them are tenants in Masdar City Square itself.
How much did the Masdar City Square acquisition cost?
The acquisition price was AED 918 million. Reuters/Refinitiv coverage republished by Zawya and TradingView reported the amount as approximately US$250 million, which is a rounded currency equivalent. The public announcements do not disclose the seller, the financing structure, the purchase price allocation among the buildings, or the amount contributed separately by Aldar and Mubadala.
The releases also do not state a separate legal closing date. Therefore, the safest wording is that the acquisition was announced on 16 September 2026 and that the property itself was completed in Q1 2026. Construction completion and transaction completion are not necessarily the same event.
Why is this acquisition important?
The transaction expands an existing Abu Dhabi real estate platform focused on Masdar City. Following the acquisition, the joint venture says its portfolio includes more than 158,000 square metres of commercial net leasable area, a weighted average unexpired lease term of approximately 5.2 years, and more than 1,400 fully occupied residential units. The portfolio includes 17 Masdar City Green REIT assets and The Link at Masdar City.
For Aldar and Mubadala, Masdar City Square adds a recently completed office asset with high reported occupancy and institutional tenants. This supports the partners’ stated strategy of building a recurring, income-generating portfolio in a location connected to clean energy, artificial intelligence, education, research and advanced technology.
However, the acquisition alone does not prove that Abu Dhabi-wide office rents, property prices or investment yields are rising. Those would require separate market data. The directly supported conclusion is narrower: two major Abu Dhabi institutions are increasing their exposure to a highly occupied office cluster in a strategic innovation district.
What are Aldar, Mubadala and Masdar City’s roles?
Aldar Properties is the real estate developer, investor and asset-management partner in the transaction. It co-acquired Masdar City Square through the joint venture with Mubadala.
Mubadala Investment Company is an Abu Dhabi sovereign investor. It is the co-investor in the joint venture and has positioned the transaction as part of its long-term investment approach to infrastructure and assets supporting future-focused sectors, economic diversification and the UAE’s net-zero ambitions.
Masdar City is the sustainable urban community, business hub and free-zone environment where the property is located. Masdar City is a subsidiary of Mubadala Investment Company. The 2026 announcement names Masdar City as the location and quotes its chief executive, but it does not identify Masdar City as a separate acquiring party.
In September 2024, Aldar and Mubadala announced a broader partnership involving four joint ventures to develop and manage prime Abu Dhabi real estate assets valued at more than AED 30 billion. That announcement described the overall partnership as 60% owned by Aldar and 40% by Mubadala.
Because the September 2026 acquisition release does not restate the 60:40 split for the specific Masdar City-focused joint venture, it is better to attribute the ownership ratio to the 2024 partnership announcement rather than present it as a newly disclosed transaction-specific term.
What sustainability features does Masdar City Square have?
The official transaction release says Masdar City Square has LEED Platinum and WELL Gold sustainability credentials and includes solar photovoltaic systems, passive-cooling techniques and a net-zero-energy Department of Energy headquarters.
Masdar City also lists Masdar City Square among developments associated with WiredScore Platinum and SmartScore Gold certifications. These certifications relate to digital connectivity and smart-building capabilities.
One qualification is important for accurate reporting: the official materials use both completed-certification language and design-oriented language such as “designed to achieve” LEED Platinum and WELL Gold. This article therefore attributes the certification information to the official announcement rather than claiming an independently verified certificate date. Similarly, no source reviewed for this article confirms that the Department of Energy headquarters has already received the International Living Future Institute’s performance-based Zero Energy Certification.
Does the acquisition mean Masdar City Square is still under development?
No. The latest acquisition announcement says the seven buildings were completed in Q1 2026 and were 99% occupied on 16 September 2026. Some older Masdar City webpages and brochures may still describe the project as upcoming because they were created before completion. For current status, the September 2026 acquisition announcement is the more recent source.
The announcement does not disclose a new construction phase, refurbishment budget, expansion timetable or additional development plan for Masdar City Square.
What does the deal mean for Abu Dhabi’s real estate market?
The deal demonstrates continued institutional interest in specialised commercial real estate connected to Abu Dhabi’s growth sectors. Masdar City brings together clean-energy companies, technology businesses, research organisations, universities and government-related institutions. A near-fully occupied office complex in that ecosystem can provide exposure to those sectors through leased real estate.
The transaction also shows that Abu Dhabi’s real estate strategy is not limited to residential development. The joint venture’s stated portfolio combines commercial and residential assets, while Masdar City Square is specifically positioned as a knowledge-economy and innovation-oriented office property.
Market-wide conclusions should remain measured. The public information does not include a cap rate, rent roll, valuation report, tenant-by-tenant lease terms or an independent assessment of the property’s market value. Those details would be needed to evaluate the acquisition as a benchmark for Abu Dhabi office pricing.
Bottom line
Aldar and Mubadala’s AED 918 million acquisition of Masdar City Square is a significant addition to their Abu Dhabi real estate partnership. The asset is a completed, seven-building office complex with more than 47,000 square metres of net leasable area and 99% reported occupancy. Its location in Masdar City gives the investment exposure to clean energy, artificial intelligence, research and technology-driven economic activity.
The most accurate interpretation is that the deal scales an existing income-generating real estate portfolio. It should not be described as a new construction launch, a disclosed seller transaction, or proof of a market-wide Abu Dhabi office boom unless further evidence becomes available.
