Domain Name Trends Analysis: What Categories Are Growing

The domain market is shaped by the same forces that drive the broader economy — technology shifts, regulatory changes, cultural movements, and emerging industries create demand for new categories of domain names while mature categories consolidate. Tracking these trends gives investors an edge in identifying growth categories before prices fully reflect the opportunity.

The AI Domain Explosion

Artificial intelligence is the dominant category story of 2024 and 2025. The .ai extension grew from approximately 50,000 registrations in 2018 to over 900,000 by late 2025, with the registry on track to surpass 1 million registrations by early 2026. Growth accelerated after ChatGPT’s launch in November 2022, and the pace has not slowed as AI applications expand across every industry.

Beyond the .ai extension, AI-keyword .com domains have seen dramatic price appreciation. Any .com domain containing “AI” as a prefix, suffix, or standalone keyword has gained value as startups race to signal their AI capabilities through their domain name. NameBio data shows that domains containing “AI” sold at an average premium of approximately 40 percent over comparable non-AI keyword domains in 2024.

The trend extends to specific AI subcategories: domains related to AI agents, AI automation, AI chatbots, and AI-powered industry solutions (AI + legal, AI + healthcare, AI + finance) are among the fastest-appreciating keyword categories in the aftermarket.

The broader technology sector continues to drive demand for short, brandable domains. Startup naming trends in 2025 favor invented words, compound neologisms, and abbreviated forms over descriptive keyword domains. This creates ongoing demand for pronounceable four-to-six-letter .com domains that can serve as startup brand names.

Developer-focused extensions (.dev, .io, .app) maintain steady registration growth, though .io’s growth has slowed relative to .ai. The .dev extension, operated by Google, has gained traction for developer documentation sites, open-source project pages, and developer-focused SaaS tools.

Cloud computing, cybersecurity, and fintech domains remain strong categories with consistent buyer demand. The permanent shift toward remote work and digital-first business operations sustains pricing for domains related to collaboration, productivity, and digital infrastructure.

Health and Wellness Domains

Health-related domain demand has grown steadily since the pandemic accelerated telehealth adoption. Domains related to mental health, telehealth, wellness apps, and health technology maintain strong interest from both end users and investors.

The growth of GLP-1 weight loss drugs (Ozempic, Wegovy) has created a subcategory boom for weight loss and pharmaceutical-adjacent domain names. Domains related to telemedicine prescription services, health coaching, and wellness tracking continue to appreciate.

Health domains carry additional considerations for investors. These topics fall under YMYL (Your Money or Your Life) content guidelines, meaning Google applies higher scrutiny to health-related websites. Developed health domains with authoritative content and proper medical disclaimers command significant premiums over undeveloped names.

Sustainability and Green Energy

Environmental and sustainability domains represent a growing long-term category driven by government policy, corporate ESG commitments, and consumer preference shifts. Domains related to solar energy, electric vehicles, carbon credits, sustainable agriculture, and renewable energy technology have seen consistent appreciation.

The Inflation Reduction Act in the United States and similar legislation in Europe have directed billions in investment toward clean energy, creating business formation in sectors that need domain names. Solar installation companies, EV charging networks, energy storage businesses, and carbon accounting firms are all active domain buyers.

Emerging Markets and International Domains

Country-code TLDs have seen significant growth as a category, with registrations up 61 percent year-over-year collectively. This growth is driven by both domestic adoption in developing markets and creative repurposing of ccTLDs as generic alternatives.

The .in (India) extension benefits from India’s massive and growing internet population. The .ng (Nigeria) extension has gained traction alongside Nigeria’s booming tech sector. The .sa (Saudi Arabia) extension is growing as Vision 2030 drives digital transformation investment.

For investors, international domain opportunities require understanding local market dynamics, payment processing, and cultural factors that affect naming preferences. The payoff can be substantial — premium one-word ccTLD domains in markets with rapid internet adoption often appreciate faster than equivalent .com names.

New gTLD Program Round Two

ICANN’s planned reopening of the new gTLD application window in 2026 represents a structural shift in the domain market. Organizations, cities, and companies will be able to apply for their own custom domain extensions, creating new namespace and potentially new investment categories.

The first-round new gTLDs (.xyz, .online, .site, .shop) have collectively posted 13.5 percent year-over-year registration growth, demonstrating that the new extension model has commercial viability even if no single extension challenges .com’s dominance.

For investors, the second-round gTLD program creates opportunities in both the new extensions that emerge and the established extensions (.com, .net, .io) that benefit from increased awareness of domain names as a category.

Market Size and Growth

The global domain name market is projected to grow from $10.49 billion in 2026 to $16.57 billion by 2035, reflecting a compound annual growth rate of 5.1 percent. The aftermarket specifically is projected to grow from $0.68 billion in 2025 to $1.17 billion by 2033. Total domain registrations reached 378.5 million by late 2025, up 4.5 percent year-over-year.

These macro numbers confirm that the domain market continues to expand, driven by new business formation, internet adoption in emerging markets, and increasing recognition of domains as business-critical assets.
