Which Domain Names Sold for the Highest Prices?

Domain names are a critical asset for any business. To build brand recognition and establish an online presence, securing the right domain is essential. Some domains sell for fortunes, while others carry little market value. Below we review ten of the most expensive domain-name sales in history and highlight the factors that typically drive premium prices, such as memorability, keyword value, industry relevance, and short length.

CarInsurance.com: $49.7 million

In 2019, CarInsurance.com was auctioned for $49.7 million. The site, which helps users compare auto insurance quotes, was acquired by digital marketing firm Quinstreet. This sale remains the highest publicly reported price for a domain name. Although the figure is large, high revenues in the insurance vertical make such investments sensible: companies with strong traffic and conversion in insurance can generate substantial returns. For example, in 2021 CoverHound—another insurance-related business—was acquired for a reported $618 million, illustrating the scale of value in this sector.

Insurance.com: $35.6 million

On September 3, 2020, Insurance.com sold for $35.6 million, setting a new record at the time for domain sales. The buyer was Quinstreet, a public marketing company that owns several insurance-related sites, including Compare.com. Quinstreet planned to deploy Insurance.com to power a new site that aggregates quotes from multiple insurers. The sale underscores how a strong, industry-specific domain can be central to a company’s online strategy as consumers increasingly research and purchase insurance products online.

VacationRentals.com: $35 million

In 2007, VacationRentals.com sold to HomeAway for $35 million, a sum that set records at the time. Founded in 1996, the site became a popular destination for travelers seeking short-term rental accommodations worldwide. VacationRentals.com’s high sale price reflects not only its strong brand recognition but also its long-standing presence in the travel market, highlighting how longevity and clear descriptive naming boost domain value in tourism and hospitality.

PrivateJet.com: $30.18 million

PrivateJet.com changed hands in 2019 for $30.18 million. The site functions as a marketplace connecting aircraft owners with charter operators and private-jet services. The seller had originally acquired the domain in 2012 for $250,000, making the later sale a significant return on investment. The buyer was an affiliate of UBS, one of the world’s largest investment banks. The transaction demonstrates how premium, descriptive domains in niche luxury markets can command high prices as demand for private aviation services grows.

Voice.com: $30 million

Voice.com sold for $30 million in a high-profile deal. The buyer—a company focused on voice-activated search and audio-first experiences—intended to use the domain to build and promote voice-enabled services. The sale reflects the increasing strategic importance of voice search and audio platforms and shows how single-word, category-defining domains retain exceptional marketing power.

Internet.com: $18 million

In 1995 Netcom On-Line Communications Services Inc. paid $18 million for Internet.com, making it one of the earliest record-setting domain purchases. The domain later became part of Quinstreet’s portfolio. Internet.com has served both as a direct-traffic destination and as a strong brand asset supporting other Quinstreet properties that address online marketing, finance, and insurance. Generic, highly relevant domains that capture direct traffic remain among the most valuable digital real estate assets.

360.com: $17 million

In 2015 the domain 360.com sold for $17 million. The domain—originally associated with Chinese internet company Qihoo 360—was acquired by a U.S. investment firm in a deal that valued the site and its related services highly. Short, numeric domains that carry international recognition and existing brand equity can command significant prices because of their broad appeal and strong recall.

Insure.com: $16 million

Insure.com sold in August 2005 for $16 million, making it one of the highest-priced insurance-related domain sales. Launched in 1998 as a leading online resource for insurance information, the site offers quotes, articles, tools, and agent listings to help consumers compare coverage options. Its comprehensive content and keyword-rich name made it an especially valuable property within the insurance market.

Fund.com: £9.99 million

Fund.com sold in 2008 for £9.99 million, ranking it among the most expensive domains ever sold. Guggenheim Partners purchased the domain with plans to use it as a financial-services resource for investors, though the site was never launched by the buyer and was later sold to a holding company in 2014. The case illustrates both the perceived value of generic, finance-related domains and the risk that not every high-value purchase leads to a long-term website operation.

Sex.com: $14 million

Sex.com is one of the most famous domain sales in history, changing hands in November 2010 for $14 million. First registered in 1994, the domain’s complicated ownership history involved years of litigation, a high-profile fraud case, and eventual restitution to the original registrant before later sale. Its value stems from extreme keyword relevance and traffic potential in the adult market, and its sale remains an emblematic example of the premium prices a single-word domain can achieve.

These sales demonstrate that a domain’s value is shaped by several consistent factors: industry relevance, memorable and concise naming, keyword strength, existing traffic, and the strategic objectives of buyers. Premium domains remain a powerful tool for marketing, search visibility, and direct traffic, and savvy companies continue to invest heavily in domain names that align closely with their core business and customer search behavior.
