Recent four-letter sales
Asking prices and realized prices are not the same thing. Estimate what a name is worth from comparable public sales before you make an offer.
Why four-letter domains keep selling
Brandable patterns
CVCV and CVVCV combinations read like real product names. Companies like Uber, Lyft, and Stripe all sit in the four-letter brand zone, which is why startups still chase this length first.
Startup-friendly price
The four-letter floor sits well below three-letter pricing while still being short and memorable. Plenty of inventory exists in the low-thousands range for new founders.
Liquid resale market
Aftermarket platforms move four-letter inventory faster than five-plus letter brandables. Investors and brokers actively trade the category, which keeps a real bid-ask spread on quality patterns.
