What is the AI companies office leasing boom? The AI companies office leasing boom is the surge in commercial office demand driven by artificial intelligence firms that leased over 3.5 million square feet across New York City and San Francisco in 2025, making AI the single largest driver of office market recovery in both cities. Bloomberg reported on March 19, 2026 that AI companies are flooding into Manhattan, with Anthropic, Palantir, OpenAI, and dozens of startups signing leases and hiring aggressively, while CBRE data shows AI firms now occupy 7 million square feet in San Francisco alone, representing 12% of the city's total occupied office space. For CRE investors, this trend represents the most significant positive demand signal for office assets since the pandemic.

Key Takeaways
- AI companies leased 1 million square feet in Manhattan in 2025, a 152% increase from 2024, and are seeking an additional 1.4 million square feet in 2026
- In San Francisco, AI firms leased 2.5 million square feet in 2025 and now occupy 7 million square feet, representing 12% of total occupied office space
- AI tenants pay premium rents of approximately $88 per square foot in NYC versus the $78 citywide average, boosting NOI for landlords with AI exposure
- SL Green's trophy assets hit 100% occupancy driven by AI tenants like Harvey AI, with the REIT expecting a record 900,000 square feet of leasing in Q1 2026
- New York is becoming a serious competitor to the Bay Area for AI talent, challenging the assumption that AI is a Silicon Valley-only phenomenon for CRE purposes
The Numbers Behind the AI Office Boom
The data tells a compelling story for CRE investors. According to Bloomberg and CBRE, AI-driven office leasing has reached levels that are reshaping the fundamentals of the two most important U.S. office markets:
New York City:
- AI firms added approximately 1 million square feet across Manhattan in 2025, a 152% jump from the prior year
- AI companies are currently seeking an additional 1.4 million square feet of office space
- Tech and AI firms accounted for 15% of Manhattan leasing volume in 2025, up sharply from 9% the previous year
- Legacy tech companies investing in their own AI capabilities added another 2.1 million square feet
- The momentum lifted New York to its best year for office leasing since 2014, according to Savills
San Francisco:
- AI companies leased 2.5 million square feet across San Francisco in 2025
- AI firms now occupy 7 million square feet, representing 12% of San Francisco's total occupied space
- Office leasing demand hit an all-time high, with tenants seeking about 8 million square feet total
- AI companies accounted for 2.8 million square feet, or 35%, of active demand according to CBRE
For CRE investors who have been cautious about office assets since 2020, these numbers represent the first structural demand catalyst that could justify re-entering the office sector, at least in markets with strong AI company presence.
Who Is Leasing and Where
The AI companies driving this demand are not small startups taking short-term subleases. They are well-capitalized firms signing long-term, full-floor leases in trophy buildings:
- OpenAI: The maker of ChatGPT, which recently surpassed $25 billion in annualized revenue, has expanded its office footprint across both San Francisco and New York as it scales toward a potential IPO at up to $1 trillion valuation
- Anthropic: The Claude AI developer has established a significant presence in both San Francisco's Mission District and New York, becoming one of Manhattan's most prominent new tech tenants. Anthropic recently launched a $100 million Claude Partner Network that is driving additional hiring
- Harvey AI: The legal AI platform expanded at SL Green's One Madison Avenue by 92,663 square feet, bringing its total footprint to 185,326 square feet in a single building
- Palantir: The data analytics firm has been aggressively expanding in Manhattan as its AI platform gains enterprise traction
- Clay: The AI-powered sales intelligence company also leased significant space at SL Green properties, contributing to record occupancy
These tenants share common characteristics that CRE investors should note: they are well-funded (often backed by billions in venture capital), growing rapidly, willing to pay premium rents, and prefer high-quality Class A and trophy office space to attract and retain talent.
Premium Rents and Tenant Quality
AI companies are not just filling vacant space. They are paying above-market rents and improving the quality of landlords' tenant rosters. According to market data, AI firms in New York agreed to pay approximately $88 per square foot on average in 2025, compared to the citywide average of $78 per square foot. That 13% premium reflects several factors:
- Talent competition: AI companies compete fiercely for engineers, researchers, and product managers. Premium office space with modern amenities, natural light, and transit access is a recruiting tool
- Speed to occupancy: AI startups flush with venture capital prefer move-in-ready, tech-enabled suites because they cannot afford long construction timelines. Landlords who invest in pre-built suites capture these tenants at premium rents
- Location preferences: AI firms cluster in prime Midtown, Midtown South, and SoHo corridors in New York, and in the SoMa and Mission districts in San Francisco, driving rent growth in already strong submarkets
- Credit quality: Companies like OpenAI, Anthropic, and Palantir bring institutional-grade credit quality, reducing landlord risk and supporting higher property valuations
For CRE investors, this translates to higher NOI per square foot from AI tenants compared to traditional financial services or legal tenants. A 200,000 square foot lease at $88 per square foot generates $17.6 million in annual gross rent versus $15.6 million at the $78 average. Over a 10-year lease term, that $2 million annual premium compounds significantly into property value.
SL Green: A Case Study in AI-Driven Office Recovery
SL Green Realty Corp (NYSE: SLG), Manhattan's largest office landlord, provides the clearest case study of how AI leasing is translating into financial performance for CRE investors:
- 100% occupancy: AI leasing by Harvey AI and Clay pushed SL Green's trophy asset One Madison Avenue to full occupancy
- Record pipeline: SL Green expects over 900,000 square feet of leasing in Q1 2026, the highest first-quarter volume in its 28-year history
- Strong early momentum: Over 830,000 square feet of office leases were signed in the first 65 days of 2026 across 44 transactions
- One Madison Avenue: The redeveloped 1.4 million square foot trophy tower achieved 100% occupancy, with Harvey AI alone occupying over 185,000 square feet
SL Green CEO Marc Holliday called it "likely the best [quarter] in our entire history," adding that the results are "the ultimate response to the false narrative that AI is shrinking the workforce in New York City." This observation is critical for CRE investors: even as AI automates many functions at other companies, the firms building AI need large physical offices to house the human talent creating these systems.
New York vs. San Francisco: A Two-City AI Office Race
A surprising development for CRE investors is New York's emergence as a serious competitor to the Bay Area for AI company headquarters and expansion. While San Francisco remains the epicenter of AI startup formation, New York is capturing an increasing share of AI company growth for several reasons:
- Proximity to financial clients: Many AI companies, especially those targeting financial services (like Harvey AI for legal and Bloomberg for data), benefit from being near their clients in New York
- Talent pool diversity: New York offers access to talent across business functions, not just engineering, which matters as AI companies scale beyond R&D into sales, marketing, and operations
- Cultural appeal: For recruiting purposes, some AI employees prefer New York's urban environment over San Francisco's tech monoculture
- Cost relative to quality: While New York rents are higher in absolute terms, the quality of available inventory in Midtown and Hudson Yards has attracted AI companies that want world-class space
For CRE investors, this geographic diversification of AI demand means that the AI office thesis is not limited to San Francisco. New York, and potentially emerging AI hubs like Austin, Seattle, and London, present opportunities to capture AI-driven office demand growth.

The Paradox: AI Creates and Destroys Office Demand Simultaneously
CRE investors must reconcile a seeming contradiction: AI companies are driving record office demand while simultaneously building products that automate office jobs at other companies. This paradox has a logical resolution:
- Short to medium term (2026 to 2030): AI companies are in a hyper-growth hiring phase. Building frontier AI models requires thousands of engineers, researchers, and support staff who need physical office space. This demand is large and immediate.
- Medium to long term (2030 and beyond): As AI products mature and automate more functions at client companies, traditional office tenants in banking, legal, and professional services may reduce their footprints. This demand destruction is gradual and uncertain in timing.
The practical implication for CRE investors is that AI-driven office demand is currently a net positive for markets with strong AI company presence, but a net negative for markets dependent on the traditional office tenants that AI is disrupting. The winners are trophy and Class A buildings in AI hub submarkets. The losers are Class B and C buildings in markets without AI company presence.
With CRE sales volume forecast to increase 15 to 20% in 2026, investors who can identify the AI-driven winners early will be positioned for outperformance.

Frequently Asked Questions
Q: How much office space are AI companies leasing?
A: AI companies leased approximately 3.5 million square feet across New York City and San Francisco in 2025 alone. In NYC, AI firms added 1 million square feet (a 152% increase from 2024) and are seeking an additional 1.4 million square feet. In San Francisco, AI firms now occupy 7 million square feet total, representing 12% of the city's occupied office space, with 2.5 million square feet leased in 2025. These figures do not include legacy tech companies investing in AI capabilities, which added another 2.1 million square feet in Manhattan.
Q: Are AI companies good tenants for CRE investors?
A: AI companies are generally premium tenants. They pay above-market rents (approximately $88 per square foot in NYC versus the $78 citywide average), prefer long-term leases in trophy buildings, and bring strong credit quality backed by billions in venture capital funding. Companies like OpenAI ($25 billion annualized revenue), Anthropic, and Palantir represent institutional-grade credit. The main risk is that AI companies are in a growth phase that could slow if venture funding tightens or if AI adoption rates plateau.
Q: Will AI office demand last or is this a bubble?
A: The demand is supported by structural factors including massive AI infrastructure investment (hyperscalers plan to spend $650 billion in 2026 alone), rapidly growing AI revenues, and an expanding talent pool that needs physical workspace. However, CRE investors should monitor two risks: venture capital pullback that could slow AI startup growth, and the longer-term paradox that AI products may reduce overall office demand by automating jobs at traditional tenant companies. The best strategy is to focus on trophy assets in AI hub submarkets where demand is most durable.
Q: Which CRE markets benefit most from AI office demand?
A: New York City (especially Midtown, Midtown South, and Hudson Yards) and San Francisco (SoMa and Mission districts) are the current leaders. New York is becoming a serious competitor to the Bay Area, with tech and AI firms now accounting for 15% of Manhattan leasing volume. Emerging AI hubs like Austin, Seattle, and London may also see growing demand. The key factor is proximity to AI talent, which concentrates near top research universities and existing tech company clusters.
