The 50 Most Expensive Domain Sales of All Time

The domain name market has always attracted big money, but 2025 shattered every ceiling anyone thought existed. In April 2025, Crypto.com CEO Kris Marszalek paid $70 million in cryptocurrency for AI.com — more than double the previous publicly confirmed record. The deal was kept confidential until Super Bowl LX weekend in February 2026, when Marszalek unveiled a consumer AI agent platform built on the domain.

That single transaction reshaped the top of the list. But AI.com is only part of the story. Below is the most comprehensive, up-to-date ranking of the largest publicly confirmed domain sales ever recorded — drawn from DNJournal, NameBio, SEC filings, and broker confirmations.

The Top 10: All Eight-Figure Territory

These are the only ten domains ever publicly sold for $10 million or more in a clean, disclosed cash transaction.

The story behind #1: AI.com

AI.com's path is one of the most interesting in domain history. The domain passed through multiple owners across three decades — most recently sold by Kuwaiti-owned Future Media Architects to Malaysian entrepreneur Arsyan Ismail in September 2021 for an estimated $11 million. Ismail held the domain for roughly four years, famously redirecting it to various AI platforms (ChatGPT, Grok, Gemini) for attention, before listing it at $100 million in March 2025 through broker Larry Fischer of GetYourDomain.com.

Marszalek closed the deal for $70 million in cryptocurrency in April 2025, held the news quiet for nearly ten months, then launched an AI agent platform with a Super Bowl LX commercial. The site crashed under the traffic.

The Seven-Figure Club: #11–30

The gap from $10M to $1M represents a bigger pool of sales but still an extremely selective tier. These are domains that sold publicly between $1.5M and $10M.

Notable 2025 Additions: #31–50

2025 was a blockbuster year for the domain aftermarket. Commerce.com became the first confirmed seven-figure sale of the year at $2.2M, Icon.com cracked the top 10 at $12M, and the .ai extension finally crossed the million-dollar line with Fin.ai.

What the Data Shows: Five Big Patterns

1. Single-word .com still dominates

Of the top 50 sales, 47 are single-word .com domains. This mirrors the broader market — of the top 100 domain sales in 2024, 63 were single-word domains while only 7 were two-word and just 1 was three-word. The scarcity premium on dictionary words in .com is the single most powerful force in this market.

2. The AI boom is rewriting the TLD hierarchy

Five years ago, a .ai sale above $100,000 was front-page domain news. In 2025, the average .ai aftermarket sale price crossed $239,000. Fin.ai became the first confirmed $1M+ .ai sale, and dozens of six-figure .ai transactions filled the charts. The extension's registration base has grown 16x in three years — from 60,000 in 2022 to over 1 million by January 2026.

3. Insurance and adult content historically paid the biggest cash numbers

Before the AI era, four of the top 20 sales were insurance-related (CarInsurance.com, Insurance.com, Medicare.com, and others) and four were adult-industry (Sex.com twice, Porn.com, Porno.com). These are the two verticals where customer lifetime value historically justified paying eight figures for a domain.

4. Crypto payments are now mainstream at the top

AI.com, Crypto.com's original rebrand from Monaco, and several NFT-era sales (NFTs.com among them) were all paid in cryptocurrency. For high-value transactions with international parties, crypto now rivals wire transfers for speed and finality.

5. Strategic buyers pay far above "appraisal" value

Every automated valuation tool — GoDaddy GoValue, Estibot, our own engine — would have estimated AI.com in the low-to-mid eight figures. The domain sold for $70M because an end-user with strategic intent and deep pockets wanted it. This is the fundamental limit of any appraisal: it values the domain as an asset, not as a category-defining brand.

What These Numbers Don't Show

A few caveats worth stating plainly:

• Private sales are missing. Industry estimates suggest 30–50% of high-value domain transactions are never publicly disclosed. There are almost certainly sales above $10M that aren't on this list.
• Bundled acquisitions are excluded. When a company buys another company, the domain may be worth more than the official cash price suggests. Cars.com's $872M intangible asset valuation is the classic example.
• Values are nominal, not inflation-adjusted. Sex.com at $14M in 2005 would be worth roughly $22M in 2026 dollars.
• The ceiling keeps moving. Before 2019, nothing had crossed $20M. Before 2025, nothing had crossed $50M. The next record could come at any time.

Thinking About Buying a Premium Domain?

You don't need $70 million to own a strong name. Quality domains exist across every price tier, from $10 reg-fee hand-registrations to $10,000 aftermarket grabs to seven-figure category killers. The key is knowing what you're actually paying for.

Before buying any domain — new or aftermarket — run it through a valuation tool. If the asking price is 10x the appraised value, you're paying for a seller's optimism, not the market. If it's 2x, you might be getting a deal.

Final Thoughts

Every few years the domain market seems to hit a ceiling. It never holds. AI.com's $70M looked like an impossible number right up until it happened, just as Voice.com at $30M looked impossible in 2019 and Insurance.com at $35.6M looked impossible in 2010.

The pattern is always the same: a new category emerges (insurance, search, crypto, NFTs, AI), a strategic buyer with deep pockets identifies the perfect domain, and the record falls. The next record-breaker is probably already sitting in a portfolio somewhere, waiting for the right buyer and the right moment.

Whether that's your domain or not — it's worth knowing.
