Congrats to Porkbun on reaching 4 million domains under management.  That’s quite impressive, and even more impressive is the customer count:

• Last October, when they had 3 million domains under management, they had 450,000 customers.  So each customer on average had 6.7 domains.
• Now with 4 million domains, they have 750,000 customers.  That means each customer has 5.3 domains.

In other words, customer count is growing faster than domain count.  While domains have grown by 33%, customers have grown by 67%.  That’s got to feel good to Porkbun management.

Porkbun’s growth trajectory has accelerated notably since its inception in 2015:

• First million: 7 years
• Second million: 2 years
• Third million: 1.25 years
• Fourth million: .75 years

Porkbun’s Strategy

The number of active customers is crucial because it can offer a clearer picture of a registrar’s demand and market position. Many registrars can inflate domain numbers through discounts or bulk sales to resellers, which does not genuinely reflect user demand.

Porkbun explicitly says it sells most domains at cost, defined as the registry wholesale price + ICANN fee + payment-processing fee. It says any markup on ordinary domains is typically $1 or less. For .com, its published breakdown as of October 2025 was $10.26 wholesale + $0.20 ICANN + $0.62 card processing = $11.08 retail, zero markup.

So how do they make money?  Adjacent services: web hosting, WordPress hosting/site-building products, email hosting, etc.

You could say domains are their “loss leader” but really the best term is that domain sales are their customer acquisition cost.  And the nice thing about this particular CAC is that the marginal cost is zero.  You built the platform, get all the approvals, and automate things, and then you can sell domains to any number of million people for the same cost.

Domain sales are highly commoditized, so the real moat is customer service.  As long as customers are happy, they’ll stick around because they’re not going to find lower prices elsewhere.  In this model, domains are not a recurring profit center but rather a recurring customer relationship.

Porkbun also offers a marketplace where customers can resell domains for a 7% commission (compared to much higher rates at Sedo, Afternic, etc.).  Cheap registration attracts portfolios, which create aftermarket inventory, which generates commissions.

Lots of Room to Grow

GoDaddy leads the market with 52.7 million .com domains, and Porkbun does not rank among the top fifteen registrars for total .com domains.  But it’s growing and its strategy is succeeding.  How long to 5 million?  Maybe as soon as later this year.
