Every year for the last decade, someone has written an article predicting the decline of .com. The argument is always plausible: new TLDs are shorter, cheaper, and often more descriptive. Why would anyone keep paying a premium for an arbitrary three-letter suffix from 1985?
The answer, persistently, is “because the buyers do.” Whatever the theoretical case against .com, the practical data points the other way. This article looks at what that data shows and what it doesn’t.
The sales data
Every major public sales report — NameBio year-end, Sedo quarterly, DNJournal weekly — breaks sales down by TLD. The pattern is consistent year over year:
- .com sales account for roughly 65-75% of the total dollar volume in the aftermarket.
- .com sales account for roughly 55-65% of the total transaction count.
- The gap between .com median price and non-.com median price has held at roughly 2-4× for eight consecutive years.
These numbers don’t tell you what will happen in the next decade. They tell you that the shift toward alternative TLDs predicted in 2015, 2018, and 2022 didn’t happen in 2016, 2019, or 2023.
Why the premium holds
A few structural reasons the .com premium persists:
Recall under load. Under cognitive pressure — in a conversation, on a phone call, from a podcast — people default to .com. If a listener hears “the URL is brand.co,” roughly 30-40% of them will type brand.com anyway. This is well-documented in usability testing and hasn’t changed as alternative TLDs have grown.
Trust assumptions. Users assume .com is more legitimate than newer TLDs. This assumption is wrong — a scammer can register either — but user behavior is shaped by the assumption, not by the reality.
Existing inventory. Most valuable three, four, and five-letter .com names were registered decades ago. When a company names a new product, the alternatives that come up are “invent a word and get the .com” or “take the exact match in a newer TLD.” Funded founders nearly always choose the former.
Habit is a feature, not a bug. When a platform has decades of habit behind it, the habit itself becomes a moat. SMS didn’t go away because iMessage launched. Email didn’t go away because Slack launched. The fact that .com is old is the source of its staying power.
Where alternative TLDs actually work
This isn’t to say alternative TLDs are dead. Specific categories have matured into genuine buyer pools:
- .io for B2B SaaS and developer tools. The .io TLD trades at roughly 15-25% of its .com equivalent’s price, but the addressable buyer pool is large and active.
- .ai for AI-related products. Growing sharply; median sale price up roughly 4× since 2022.
- .co as a .com substitute in Latin America and for certain startups.
- .xyz for crypto-native projects and some consumer apps.
Each of these has a real market. The difference is that buyers in these markets self-identify with the TLD — a founder picking .io isn’t settling, they’re signaling. .com buyers, by contrast, often don’t want to signal anything.
What the data doesn’t tell you
Public sales data has limits worth acknowledging:
- It’s biased toward reported sales. Small .com transactions in the $500-3,000 band are underreported; small alternative-TLD transactions in the same band are even more underreported. True volume on newer TLDs is probably higher than the data suggests.
- Marketplaces with private-by-default reporting (Afternic private sales, direct broker deals) are entirely invisible.
- Short-term volatility — one breakout TLD having a strong quarter — doesn’t indicate a long-term shift.
What the data does show is durable: when an acquirer is making a decision that costs them real money, they default to .com at a rate that hasn’t moved in a decade.
Practical implications
For sellers:
- .com holdings should be priced with confidence; the comparable data is abundant and consistent.
- Non-.com holdings in a category you understand (e.g., .io for dev tools) can be priced competitively; those markets are real.
- Speculative holdings in newer, less-established TLDs should be sized honestly — they’re lottery tickets, not reliable inventory.
For buyers:
- If you want a name long-term for a brand you plan to build, paying the .com premium is almost always worth it. Not because alternatives are bad, but because the cost of switching later is high.
- If you need a name immediately for a project with a 1-3 year horizon, a solid alternative TLD at a fraction of the .com price is a reasonable trade.
.com isn’t going anywhere near-term. The data is clear and the structural reasons are stable. That’s an unglamorous observation but a practical one.
