Singapore’s Prime Office Vacancy Is Just 3.1% — AI Companies Are Fighting for the Remaining Floors

*By PriceVia Asia Desk | Published September 20, 2026 | Updated September 20, 2026*

Why this matters now

AI companies are expanding in Singapore as prime vacancy sits at 3.1% and little major supply is due before 2028, setting up an estimated 10% rent increase over the next year.

Key points

- Prime office vacancy is reported at a historic-low 3.1%. - Top rents are estimated to rise about 10% over the next year. - OpenAI plans more than S$300 million of investment and space for over 200 hires.

The numbers

| Metric | Value | Context | |---|---:|---| | Prime vacancy | 3.1% | Top-grade offices | | Rent forecast | ~10% | Next 12 months | | OpenAI investment | S$300m+ | Planned | | Planned lease | 100,000 sq ft | OpenAI | | New hires | 200+ | Planned | | Major supply | From 2028 | Expected timing |

What happened — confirmed facts

The Financial Times reported that OpenAI, Anthropic, Google DeepMind, Databricks and Mistral are expanding their Singapore presence as the government promotes an Asian AI hub. With no significant top-grade projects expected until 2028, technology demand meets a tight central business district market. Singapore also benefits from firms seeking a politically stable regional base.

What everyone is watching

Signed leases versus expansion intentions, and whether hiring matches the space commitments. Landlord pricing power outside the very best buildings and whether tenants decentralise to control costs.

What the market may be missing — PriceVia analysis

PriceVia analysis: AI demand is behaving like a new financial-services cluster—high-value teams competing for premium, connected space. That can lift rents even if the broader office market is less tight. The second-order effect is talent and housing cost. Office scarcity helps landlords but can make the hub less attractive if occupancy costs compound across the employee base.

Positive case

AI teams hire as planned, landlords capture higher rents and new supply arrives without a large vacancy shock.

Downside case

Companies consolidate space, remote work limits demand or the 2028 supply pipeline arrives into slower hiring.

What would change the story

Lease registrations, office completions, hiring data and sublease availability would materially change the outlook.

How to read it

Distinguish headline commitments from occupied space. Lease terms and net effective rents matter more than asking rents.

Reader checklist

- Confirm signed AI leases in a primary disclosure before changing the thesis. - Track net effective rents; headline narratives can move before the underlying evidence. - Track 2028 supply pipeline; headline narratives can move before the underlying evidence.
