NEOM: Technical Feasibility and Financial Viability
No element of Vision 2030 has generated more fascination, scepticism, and debate than NEOM. Announced in 2017 with a $500 billion budget and a mandate to create a new model for human civilisation, NEOM has become both the symbol of Saudi ambition and the lightning rod for criticism of Vision 2030’s feasibility. The project’s centrepiece — The Line, a 170-kilometre mirrored linear city designed to house 9 million residents with zero cars, zero streets, and zero carbon emissions — pushed the boundaries of what the world considered plausible urban development.
Seven years into development, with significant scope adjustments reported and billions already deployed, NEOM demands a dispassionate assessment of what is technically achievable, what is financially sustainable, and what is likely to actually be built.
What NEOM Was Announced As
The original NEOM vision encompassed an area of 26,500 square kilometres in Saudi Arabia’s northwest Tabuk Province — larger than many countries. Within this zone, several distinct components were announced:
The Line — a 170-km linear city, 200 metres wide and 500 metres tall, with twin parallel structures enclosing a continuous urban environment. Projected population: 9 million. Projected cost: undisclosed separately but the dominant budget item.
Oxagon — an octagonal floating industrial city at the Red Sea coast, positioned as a hub for advanced manufacturing, innovation, and port logistics.
Trojena — a mountain tourism destination at 1,500-2,500 metres elevation, designed for year-round outdoor recreation including skiing (leveraging the region’s cooler microclimate) and selected to host the 2029 Asian Winter Games.
Sindalah — a luxury island resort in the Red Sea, positioned as NEOM’s first deliverable and designed as a superyacht marina and ultra-luxury hospitality destination.
NEOM Bay — a coastal community and the project’s initial residential and administrative hub, forming part of the broader NEOM investment zone.
What Has Actually Been Built
Assessing NEOM’s physical progress requires separating construction activity from completion:
Sindalah is the most advanced component and appears on track for delivery. As a contained island resort of manageable scale, it represents a feasible first deliverable that will provide NEOM with a functioning asset and revenue stream.
NEOM Bay has seen significant earthworks and infrastructure development, including road access, utilities, and initial building construction. This is NEOM’s operational base and the area most visible to the limited number of visitors who have accessed the site.
The Line has seen extensive foundation work on what is reported to be a significantly shorter initial phase than the full 170 kilometres. Reports from 2024-2025 suggested the initial deliverable could be 2-3 kilometres — a dramatic reduction from the original announcement, though one that NEOM Company officials have contextualised as a phased approach rather than a permanent scaling back.
Trojena has seen earthworks and infrastructure development consistent with preparation for the 2029 Asian Winter Games, including road construction and site preparation. The games provide a hard deadline that concentrates delivery focus.
Oxagon has progressed in design and early infrastructure but appears behind The Line and Sindalah in construction advancement.
Technical Feasibility Assessment
The Line’s Engineering Challenges
The Line’s original specification presented engineering challenges without clear precedent. A detailed technical assessment must examine several dimensions:
Structural engineering. Two parallel structures, each 500 metres tall and extending 170 kilometres, would constitute by far the largest structures ever built. For context, the Burj Khalifa is 828 metres tall — a single tower. The Line proposes two continuous structures of comparable height extending more than 200 times the Burj Khalifa’s footprint length. The structural loads, foundation requirements, wind resistance calculations, and seismic considerations for such structures are beyond any existing engineering database.
A shorter initial phase (2-3 kilometres) brings the engineering within the realm of the technically achievable, though still extraordinarily challenging. At this scale, The Line resembles a very large mixed-use development — ambitious but not physically impossible.
Climate control. The original proposal envisioned a climate-controlled environment between the two structures, maintaining comfortable conditions in a region where summer temperatures regularly exceed 45 degrees Celsius. At full scale, the energy requirements for cooling an enclosed canyon 200 metres wide and 170 kilometres long would be enormous. At a reduced scale, climate management becomes more feasible, particularly if design modifications allow for natural ventilation supplemented by targeted cooling.
Transportation. The Line proposed a high-speed transit system allowing end-to-end travel in 20 minutes — implying speeds of approximately 500 km/h across the full 170-kilometre length. This exceeds the operational speed of any existing mass transit system. At a shorter initial phase, conventional transit solutions become viable.
Water and utilities. NEOM’s location in an arid zone with minimal natural water resources necessitates large-scale desalination, reflecting Saudi Arabia’s broader climate and sustainability challenges. This is technically proven — Saudi Arabia is the world’s largest desalination producer — but represents a significant ongoing operational cost and energy requirement.
Mirrored facade. The signature mirrored exterior creates engineering challenges including bird strike risks, thermal expansion and contraction management, and maintenance logistics for a reflective surface of unprecedented area. These are solvable problems but add cost and complexity.
Trojena’s Winter Sports Viability
The Trojena site at elevation benefits from genuinely cooler temperatures than coastal Saudi Arabia, with winter temperatures that can approach freezing. However, reliable snowfall is minimal, and the facility will depend heavily on snowmaking — an energy and water-intensive process. The 2029 Asian Winter Games provide a credible use case, but year-round winter sports viability at this latitude remains uncertain.
Oxagon’s Floating Industrial City
Offshore industrial facilities exist globally (oil platforms, floating production units), but a permanent floating city of the scale proposed for Oxagon would be unprecedented. The engineering is theoretically feasible but would require solving challenges of wave action, corrosion, logistics access, and worker accommodation that significantly exceed any existing offshore installation.
Financial Viability Assessment
The $500 Billion Question
The $500 billion figure has been associated with NEOM since 2017 but has never been accompanied by a public detailed cost estimate or spending schedule. Several analytical approaches can bracket the likely financial reality:
Bottom-up estimation. Industry analysts have attempted bottom-up cost estimates based on comparable construction costs, adjusted for Saudi conditions. These analyses typically suggest that the full original NEOM specification would cost well in excess of $500 billion — potentially $1 trillion or more in current dollars when the full scope of The Line, Oxagon, Trojena, and supporting infrastructure is included.
Spending to date. Publicly available information suggests NEOM has spent $30-50 billion through 2025, primarily on site preparation, infrastructure, and Sindalah development. This is a substantial figure but represents a fraction of the total budget, consistent with a project still in early phases.
Revenue projections. NEOM’s financial model presumably depends on revenue from tourism (Sindalah, Trojena), residential sales and leases (The Line, NEOM Bay), commercial leasing, and industrial zone activity (Oxagon). At full build-out, these could theoretically generate substantial revenue. But the ramp-up period — the years between initial delivery and reaching occupancy levels that generate meaningful cash flow — will require sustained external funding.
Return on Investment Scenarios
At a simplified level, NEOM’s financial viability depends on whether the assets created generate returns sufficient to justify the capital deployed. Several scenarios illustrate the range:
Optimistic scenario. NEOM delivers a scaled version of its full vision (perhaps 30-40% of original scope by 2035), attracts wealthy residents and tourists, and becomes a self-sustaining urban zone generating GDP equivalent to a mid-sized city. Under this scenario, the investment generates long-term returns through asset appreciation, tax revenue, and economic activity — though the return period extends to 2040-2050.
Base scenario. NEOM delivers Sindalah, Trojena (for the Asian Winter Games), NEOM Bay, and a reduced-scale section of The Line. These function as luxury tourism and residential assets but do not achieve the transformative economic impact of the original vision. The investment generates partial returns, with significant sunk costs in infrastructure that takes decades to fully utilise.
Pessimistic scenario. NEOM delivers its initial phase deliverables but fails to attract residents and tourists at scale, resulting in underutilised infrastructure and ongoing operational subsidies. The investment becomes a fiscal drag rather than a revenue generator.
The Workforce Challenge
NEOM’s construction requires a massive temporary workforce in one of Saudi Arabia’s most remote regions, intensifying the Kingdom’s expatriate dependency. Reports indicate peak construction employment targets of 200,000-300,000 workers at the NEOM site — a temporary city in itself, requiring housing, food, healthcare, recreation, and logistics at a scale comparable to a major military base.
Managing this workforce presents challenges:
- Recruitment in competition with other Saudi giga-projects and Gulf construction markets
- Logistics of supplying a remote site hundreds of kilometres from major cities
- Labour conditions under international scrutiny, with human rights organisations monitoring working conditions closely
- Retention in an extreme climate with limited off-site amenities
NEOM has invested heavily in worker housing and welfare infrastructure, and the project’s management has emphasised worker conditions as a priority. The challenge is structural rather than intentional — building at this scale in this location will always test workforce management capabilities.
International Comparisons
Comparing NEOM to historical megaprojects provides context:
Brasilia (built 1956-1960) created a new capital city in Brazil’s interior at a fraction of NEOM’s proposed scale. It was delivered but suffered from decades of social challenges, informal settlements, and a gap between planned and actual urban development.
Songdo, South Korea (begun 2002) was designed as a purpose-built smart city near Incheon. After two decades, it functions as a city but has never achieved its target population or the vibrant urban life its planners envisioned.
Masdar City, Abu Dhabi (begun 2008) was designed as a zero-carbon city. After 15+ years, it houses a fraction of its planned population and has substantially revised its sustainability targets.
The pattern across these comparisons is consistent: planned cities can be built, but they take much longer than projected to become living, functioning urban environments, and they typically achieve 30-60% of their original ambitions.
What NEOM Will Likely Become
Based on the available evidence, a realistic projection of NEOM in 2030-2035 includes:
- Sindalah operating as a luxury island destination — functional and potentially profitable
- Trojena operational for the 2029 Asian Winter Games with seasonal tourism thereafter
- NEOM Bay functioning as a small residential and administrative community
- The Line delivered at a fraction of its original length (perhaps 2-5 kilometres), showcasing the architectural concept and housing an initial population, with potential for extension over subsequent decades
- Oxagon at an early stage of development, potentially with an operational port facility
This outcome would represent an investment of $100-200 billion delivering assets that, while impressive, are a fraction of the original announcement. Whether this constitutes success depends entirely on the evaluator’s framework: relative to the original announcement, it is a significant scaling back; relative to what any country has achieved in comparable greenfield development, it would be extraordinary.
Implications
NEOM’s evolution from announcement to reality offers several broader implications:
For Vision 2030 credibility, NEOM’s scope adjustment is a double-edged sword. It demonstrates rational project management but also fuels scepticism about the reliability of Saudi announcements more broadly. Managing this credibility gap is an ongoing communications challenge.
For investors, NEOM presents a long-duration, high-risk, potentially high-return opportunity, and understanding the PIF’s broader investment strategy provides essential context. Those with 15-20 year horizons and risk tolerance for megaproject delivery may find value. Those seeking near-term returns should look elsewhere.
For the urban planning and engineering community, NEOM is generating genuine innovation — even a scaled-back version of The Line will push the boundaries of what has been built. The intellectual and technical capital being created has value that extends beyond the specific project.
The ultimate judgment on NEOM will be made not in 2030 but in 2040 or 2050, when the assets have had time to mature, attract users, and find their economic equilibrium. The history of great urban projects is that they are judged harshly during construction and more generously by time.
