How to Value .io vs .com vs .ai Domains in 2026

I bought DataStack.io for $380 in 2019. In early 2024, I sold it for $6,200. Not a life-changing flip, but a solid return. A month later I watched DataStack.ai sell on Afternic for $14,500. Same word. Different extension. Wildly different outcome.

That price gap tells a story about where these three TLDs sit right now, and if you're trying to value .io vs .com vs .ai domains in 2026, you need to understand the forces behind each one.

The .com Baseline Still Matters

Every Domain Valuation starts with .com. Always has. Probably always will — at least for the next decade.

The reason is simple: .com has the deepest buyer pool. When an End User (the actual business that wants to use the domain) goes shopping, most of them think in .com first. That means more demand, faster sales, and higher prices.

For a solid one-word .com in the tech space, you're looking at $15,000 to $250,000+ depending on the word. A two-word .com with commercial intent — think CloudMetrics.com or SalesLayer.com — might trade between $5,000 and $50,000. These ranges are wide because Domain Valuation isn't a science. It depends on comparable sales (what similar names actually sold for), the CPC of related keywords, and how many potential buyers exist for that exact term.

Check NameBio for recent comps. Filter by extension and word count. That's your starting point.

Here's my rule of thumb for 2026: a good .com is still worth roughly 3–8x what the same name would fetch in .io, and about 1.5–4x the .ai equivalent. But those multipliers are compressing, especially on the .ai side.

Where .io Stands After the Chagos Scare

Let's talk about the elephant in the room. In late 2023, the UK announced it would transfer sovereignty of the British Indian Ocean Territory to Mauritius. Since .io is a ccTLD (country-code top-level domain) tied to that territory, a wave of panic hit the domain community. If the territory's ISO code gets retired, .io could theoretically be phased out.

That hasn't happened. As of mid-2026, .io registrations continue, IANA hasn't made any moves to sunset the extension, and the Registry keeps operating. But the uncertainty left a mark. I've seen .io aftermarket prices dip 15–25% compared to their 2022 peaks for mid-tier names.

The startup community still uses .io heavily. If you browse Y Combinator's latest batch, you'll see plenty of .io sites. Developers trust it. It reads as "tech" to the right audience.

But here's my honest take: .io carries political risk that .com and .ai don't. Not catastrophic risk — I don't think millions of .io sites will suddenly go dark. ICANN has shown flexibility before (look at .su surviving decades after the Soviet Union dissolved). Still, this uncertainty suppresses what buyers are willing to pay, especially for five-figure purchases. Nobody wants to spend $30,000 on a domain that might have a question mark hanging over it.

For valuation purposes, I price strong .io names at roughly 12–25% of what the equivalent .com would bring. A name like CodeForge.io? Maybe $2,000–$4,500. CodeForge.com would likely fetch $15,000–$30,000.

The .ai Boom — Real or Bubble?

Both. And that's what makes .ai valuation tricky right now.

The demand is real. Every company building AI products wants an .ai domain. The extension is short, memorable, and literally spells out the technology. Anguilla (the small Caribbean island that controls the .ai Registry) is making a fortune — their registration fees run $80–$100/year at most registrars, which is steep compared to .com but nothing compared to the aftermarket prices.

I've personally sold three .ai domains in the past 18 months, all to companies building AI tools. The fastest sale took 11 days from listing to close. That kind of velocity is unusual in Domain Investing and tells you something about demand.

But there's a bubble component too. Speculators have flooded .ai with registrations. Thousands of mediocre two-word .ai names are sitting in portfolios with $5,000 BIN prices and zero inquiries. The good names sell. The average names sit.

Here's how I break down .ai valuation in 2026:

• Single dictionary words (Predict.ai, Shield.ai, Compose.ai): $20,000–$150,000+. Some of these compete directly with .com pricing. Shield.ai is literally a defense tech company that reportedly paid mid-six figures for theirs.
• Strong two-word combos with AI relevance (VoiceAgent.ai, DataClean.ai): $3,000–$25,000. The sweet spot for most flippers.
• Generic two-word names without clear AI use cases (BlueRiver.ai, MountainPath.ai): $200–$1,500. These are the names people overpay to register and struggle to sell.

The key question for .ai valuation: does the name make sense specifically for an AI company? If the answer is "not really," the .ai extension adds almost nothing. A pet grooming business is never going to buy FreshPaws.ai.

How I Actually Compare Across Extensions

When I'm deciding whether to buy a name in .com, .io, or .ai, I run through a quick mental checklist:

Who's the buyer? A Fortune 500 company will almost always prefer .com. A seed-stage startup might happily use .io or .ai. An AI-native company might actually prefer .ai over .com because it signals what they do.

What are the comps? I check NameBio for the exact name or close variations in all three extensions. If similar .ai names are trading at $8,000–$12,000 and the .com version hasn't sold publicly, that tells me the .ai market is more active for that category right now.

What are my holding costs? .ai renewals at $80–$100/year add up fast if you're holding 50+ names. .com renewals at $9–$12/year are trivial. .io sits in the middle at $30–$50/year depending on your Registrar. Over a 3-year hold, those costs change your ROI math significantly.

What's the liquidity? .com is the most liquid Domain Extension on earth. You can sell a decent .com in weeks on Afternic, Dan.com, or Sedo. The .ai aftermarket is active but thinner — fewer buyers, more concentrated in the tech sector. .io liquidity has softened. I've had .io names listed for 12+ months that would have sold in 3 months back in 2021.

The Ratio I Use for Quick Estimates

This isn't gospel, but it's served me well for ballpark pricing in 2026:

Take the .com value as your anchor. If you think TechPulse.com is worth $10,000:

• TechPulse.ai → roughly 30–50% of .com value → $3,000–$5,000
• TechPulse.io → roughly 12–20% of .com value → $1,200–$2,000

For names with strong AI relevance, push the .ai ratio higher — sometimes to 60–80% of .com value. For names with no AI angle, drop it to 15–20%.

These ratios shift by the month. A year ago I would have put .ai at 20–35% of .com. The market moved fast.

What I'm Actually Buying Right Now

I'm still buying .com when I find good names at wholesale prices. That never stops being smart.

For .ai, I'm selective. I only buy names where the AI connection is obvious and the word itself has commercial weight. I passed on a dozen "cute" .ai names last month because I couldn't picture a real company using them.

For .io, I've mostly stopped buying. Not because the extension is dead — it isn't — but because the risk-reward has shifted. The political uncertainty, the softening prices, and the rising competition from .ai in the same buyer demographic all point the same direction. I'd rather put that money into .ai names with clear end-user appeal or underpriced .coms.

If you're building a portfolio today, the split I'd suggest for someone focused on tech names: 50% .com, 40% .ai, 10% .io or other extensions. Two years ago that .io allocation would have been 25–30%. The market changed. Your strategy should too.
