Saudi Arabia's flagship linear megacity, budgeted at $500bn, has built roughly 1.4% of its planned 170km structure and is being scaled back after an internal review put full completion cost at $8.8 trillion.

Context

NEOM is a Public Investment Fund-backed megaproject in Tabuk Province, launched in 2017 as a flagship of Saudi Arabia's Vision 2030, centred on 'The Line' — a proposed 170-kilometre linear car-free city. It is included as a documented cautionary case: honest evaluation of high-ambition projects requires reporting failure to deliver, not just success stories.

Objectives

Build a 170-kilometre linear, car-free megacity within an original $500 billion budget.

Activities

By late 2025, an estimated $50 billion had been spent, but construction had reached only around 2.4 kilometres of the planned structure (roughly 1.4%); construction was suspended in September 2025 and the active construction workforce was cut by 35% since April 2025.

Results

An internal audit reported by the Wall Street Journal put the cost of completing The Line to its original design at approximately $8.8 trillion (against the original $500bn budget), with completion stretching to 2080; Saudi Arabia's Public Investment Fund has written down $8 billion from the project, and the 2029 Asian Winter Games planned for NEOM's Trojena site were indefinitely postponed on 24 January 2026.

Conclusions

Saudi Arabia's 2026–2030 budget allocates roughly 60 billion riyals ($16 billion) specifically to compensate contractors and exit long-term agreements as the project is redesigned and downsized, with leadership reportedly pivoting focus toward data centres and AI infrastructure rather than the original city-scale build.

Implementation
Indicative cost
Very high (> €5M) — Original budget $500 billion; ~$50 billion spent by late 2025 for ~1.4% of the planned structure; an internal audit put full completion cost at ~$8.8 trillion; PIF has written down $8 billion, and the 2026-2030 national budget allocates ~$16 billion (60bn riyal) to exit contractor agreements.
Time to results
Long (> 3 years) — Launched 2017; construction suspended September 2025; the original (unrevised) design implied completion stretching to 2080, before the current scale-back and redesign.
Staffing & skills
NEOM Company (Public Investment Fund subsidiary), External construction contractors (workforce cut 35% since April 2025)

Conditions for success

  • Sustained multi-decade capital commitment at very large scale
  • A stable design scope, avoiding major redesigns mid-build
  • Contractor capacity matched to a realistic budget and timeline

Common failure modes

  • Original $500bn budget dramatically underestimated true build cost (revised to ~$8.8 trillion)
  • Construction suspended and workforce cut as costs became unsustainable
  • A flagship milestone (2029 Asian Winter Games at Trojena) was postponed indefinitely
  • Project scope pivoted away from the original city-scale build toward data-centre/AI infrastructure
