Why short domains are expensive — and what short actually costs.

Three forces stack. Fixed supply: the number of N-character combinations is bounded, and every short combination in .com has been owned for over a decade. Compounding demand: every funded startup wants a short name; the buyer pool grows annually. Operating leverage: short names are easier to type, easier to say, easier to remember, easier to fit in a logo. Every one of those advantages converts to retention and trust, which is what acquirers pay for.

The result is a pricing curve where each character shaved off below eight roughly doubles the price floor. A 7-character brandable that clears at $20K becomes $40K at six characters, $90K at five, $200K at four, and seven figures at three.

The wide ranges at 6–7 characters reflect the gap between random invented strings (bottom of range) and pronounceable English words or recognizable acronyms (top of range).

Short names compound. Every saved character is a percentage point of users who type the URL correctly on the first try, a millisecond saved on every podcast mention, and a square pixel returned to the logo designer. None of these effects is individually huge. All of them accumulate across hundreds of millions of impressions over the life of a brand.

The acquirer math is even cleaner. When a strategic buys a startup, the domain is the most permanent piece of the IP transfer — it outlives every product, every team, every pivot. Five characters versus eight is the difference between absorbing a brand cleanly and printing it on every customer-facing surface for the next twenty years.

Letter-only domains have their own pricing logic because they're treated as portfolio assets first and brand assets second. LL.com is the most concentrated asset class in the domain world — 676 combinations, all owned, all worth at least a quarter million. LLL.com traded in bulk to Chinese investors in 2015 and now ranges from $30K (Chip tier) to $5M+ (Investment-grade acronyms). LLLL.com is where most realistic four-character buys land — pronounceable patterns clear at $5K–$50K.

Short real-word .coms (4–6 characters) carry a premium over invented strings of the same length. The price reflects both the scarcity of the word and the implicit SEO floor — a real word has search volume that an invented string never will. Concrete-noun .coms in this range typically clear $100K+ and frequently cross $1M for category-relevant terms.

Short .ai and .io domains are the practical alternative when the .com number doesn't pencil. Pricing relative to .com: .io typically 20–35%, .ai typically 30–50%. Three-letter .ai domains in particular are still acquirable in the $5K–$30K range, a tier that no longer exists in .com.

What counts as a short domain name?

Anything under 8 characters before the TLD. The market treats short as a continuous scale: 2 letters ($250K+ floor), 3 letters ($30K–$5M), 4 letters ($500–$200K), 5 letters ($500–$50K), 6–7 characters ($1K–$500K depending on whether the string is a real word). Each character shaved off below 8 roughly doubles the price floor.

Why are short domains so expensive?

Fixed supply meets compounding demand. There are 676 two-letter .coms, 17,576 three-letter, ~457K four-letter — every single one has been registered for over a decade. New buyers enter the market every year (now: AI startups), but no new short combinations can be created. Short names are also easier to type, easier to remember, and easier to brand — every operating advantage compounds the scarcity premium.

What's the cheapest short domain I can buy?

A random 5- or 6-character invented .com on Sedo or Afternic typically lists between $500 and $5K. A pronounceable 6-character brandable usually clears between $2K and $15K. Anything below that is either taken by a portfolio investor (and not for sale at retail) or registered as a meaningful word/acronym (and priced accordingly).

Should I buy a short .ai instead of a short .com?

If your budget is under $50K, almost always yes. A short .ai typically clears at 25–40% of the equivalent .com. Three-letter .ai domains, in particular, are still acquirable in the $5K–$30K range — a tier that doesn't exist in .com anymore.

Do short domains still matter in the age of search and apps?

More than ever. Voice interfaces, podcast mentions, and AI chat responses all favor names that can be spoken once and remembered. Short domains compound that advantage across every channel that isn't a clickable link — which is now most channels. The acquirer math is also unchanged: shorter names absorb cleaner into bigger companies.

What's the difference between a short brandable and a short generic?

A short brandable is an invented or semantically open word (Stripe, Plaid, Notion). A short generic is a dictionary word (Voice, Bolt, Pulse). Brandables typically clear at 30–60% of a same-length generic because the brandable lacks the SEO floor and the universal recognition. Founders usually pay more attention to the difference than acquirers do.
