.com vs .io vs .ai: Which TLD Holds Its Value Best in the Expired Market?

Which TLD has the strongest resale data in the expired market?

Let's start with what the numbers say. According to NamePros' 2024 domain sales report, .com domains sold on expired marketplaces averaged $2,400 per sale across 3,200 transactions. .io averaged $890 across 450 sales. .ai? Just $320 across 120 sales - but that's up 400% from 2022. The volume tells the real story.

On dead.domains, we've logged 0 expired domains for each TLD so far (we just launched, so the graveyard is empty). But the patterns from established marketplaces are clear: .com dominates liquidity, .io has a smaller but real audience, and .ai is a lottery ticket.

Is .com still king for best TLD for expired domain investing?

Yes, but the crown has some dents. .com domains expire at a rate of about 1.7 million per month (Verisign, 2024). That flood means most .com names are worthless - only about 2% sell for more than reg fee. But the top 1%? Those are the ones that fund portfolios.

I learned this the hard way. In 2022 I grabbed "fixmyprint.com" at expired auction for $12. Figured printer repair was evergreen. Sat for 18 months. Sold for $19 on Afternic. That's a 58% ROI - but after a year and a half, it felt like a loss. The lesson: .com works, but you need volume and patience.

Does .io hold value better for startups?

.io has a weirdly loyal following among tech startups. For example, "api.io" sold for $12,000 at Sedo in 2023. That's rare - most .io expired domains sell for $200-$600. The market is thinner: about 40,000 .io domains expire monthly (IANA zone file data, 2024).

The advantage? .io buyers are often well-funded startups who pay a premium for brandability. The risk is that Google treats .io as a country-code TLD (British Indian Ocean Territory) for geo-targeting, which hurts SEO for non-local businesses. That's been a headache for some buyers.

Is .ai a bubble or a real investment?

.ai is the wild card. In 2024, we saw "ai-marketing.com" sell for $35,000, but "marketing.ai" only sold for $4,500. The .ai TLD has around 320,000 registrations total (IANA, 2024), and only about 8% expire monthly. The supply is tiny.

But here's the catch: .ai renewal costs are $40-$70/year at most registrars. That kills your holding period. A .com domain at $10/year can sit for years. .ai at $60/year needs to sell fast. Prices for .ai have jumped 500% since 2022, but that's pure hype. If the AI bubble bursts, those domains become expensive wallpaper.

Which TLD has the lowest opportunity cost?

This is where most indie hackers get it wrong. A $10 .com domain sitting for 2 years costs you $20. A $60 .ai domain costs $120 in the same period. If you buy 10 of each, .com ties up $200, .ai ties up $1,200. That money could be in stocks, tools, or your next actual product.

I now stick to .com for 80% of my expired portfolio. That's a personal rule after losing about $400 on .io renewals over 3 years. The remaining 20% goes to .io and .ai only for hyper-specific keywords (e.g., "devtools.io" or "chatai.ai").

What about brandability vs. resale value?

.com wins for resale value because it's the default. When someone wants a domain, they try .com first. Namecheap's 2024 survey showed 68% of buyers prefer .com for business domains. .io has a cool factor for developer tools. .ai is trendy but risky.

Brandability matters more for end users than flippers. If you're building a product, pick whatever fits. If you're investing, forget brandability - focus on liquid keywords. "Insurance" in .com will always outsell "Apix" in .io.
