Radix Premium Domain Sales Surge: Analyzing the 1H-2026 Growth Trends

For anyone holding inventory on extensions like.tech,.space, or.online, that number matters more than the headline suggests. I've been watching these reports for years, and the renewal curve is where the real story hides.

What the 4,424 sales actually tell us

Radix logged 4,424 premium registrations in 1H-2026, and the breakdown is worth dissecting..Tech led with 1,229, followed by.space at 889,.fun at 636,.online at 509, and.store at 485. That's heavy concentration at the top, but demand held across all price tiers: 112 names commanded $5,000 per year, 37 hit $10,000, and two cleared $25,000 annually.

For your portfolio, this means buyers are still paying real money for exact-match and brandable assets on these TLDs, not just picking up token registrations..Space posted the biggest jump, landing 34% above its 2H-2025 total, which tells me end users are starting to recognize it as a legitimate extension rather than a novelty. If you're sitting on aged.space inventory, this is the kind of data point that should change your asking price.

The renewal math that flips the script

Here's the line I keep coming back to: the first-year renewal rate came in at 51%, then jumped to 73% after year two, and climbed to 84% for subsequent renewals. That pattern is the difference between a registration spike and actual recurring revenue.

If you're holding premium names on Radix TLDs, your year-one churn risk is real — almost half of buyers walk away. But once a domain survives that initial drop, the odds of renewal shift dramatically in your favor. I've seen this exact curve play out in my own portfolios, and it changes how I calculate acquisition cost. A name that costs you $1,000 to acquire but retains at 84% after year three is a fundamentally different asset than one bleeding renewals every January.

What to track in your own books

The Radix data lines up with what Domain Name Wire reported from Escrow.com: US$255 million in domain transactions during 1H-2026, up 56% year-over-year. Liquidity is clearly returning to the aftermarket, but that doesn't mean every premium registration prints money.

I'd pull your own renewal reports for any Radix TLD holdings and segment them by year. If your year-one survival rate is below 40%, your acquisition cost is too high or your pricing is misaligned. If you're above 60% at year two, you're sitting in the same zone as the market leaders and can justify holding for the long-tail renewals that actually pay the bills.

The other piece worth tracking: end-user upgrades. Radix called out IQM Quantum Computers moving from meetiqm.com to iqm.tech ahead of its Nasdaq debut — a roughly $1.8 billion valuation riding on an exact-match domain. Keep your eyes on premium names in tech and science verticals; corporate rebrands onto Radix extensions are becoming a real exit lane, and the comps are starting to matter.
