Frequently asked questions
How do I know these domains are actually owned by NameIndex?
Every NameIndex portfolio name is held directly in the owner's registrar account at Spaceship or Afternic — verifiable via public WHOIS on demand. We publish transaction history, share comp reports at /comps, and will provide proof of ownership before any escrow is opened.
What payment methods do you accept?
Bank wire transfer for transactions above $10,000 (preferred — no platform fee). PayPal or Stripe for offers below $10,000. All payments are held in escrow before the domain is transferred, so funds never release without the buyer receiving the asset first.
Do you use an escrow service?
Yes — Escrow.com is recommended for every transaction regardless of size. The buyer funds escrow, we push the domain into the buyer's registrar account, and funds release only after the buyer confirms the transfer. Both parties pay a small escrow fee; the domain itself is never at risk during settlement.
How long does the transfer take after I buy?
Typical timeline is 1–5 business days once escrow is funded. For Spaceship or Afternic portfolio domains, push transfers usually complete within 24–48 hours. Registrar-to-registrar transfers (.ai, .io, .tech, etc.) take 3–5 days depending on TLD registry approval. Buyer is kept updated at every step.
Can I negotiate the listed price?
Yes — every offer is reviewed. Listed prices are comp-justified (see /comps for the underlying sales data), but well-reasoned offers below the listed price are taken seriously, especially from buyers who can articulate intended use, launch timeline, and budget context. Counter-offers are grounded in the same comp set, never arbitrary.
How do I buy a premium AI domain from NameIndex?
Three steps: (1) browse the portfolio and pick a name that matches your buyer profile and cluster thesis, (2) submit an offer through the inline form below with your intended use, timeline, and budget context, (3) we respond within 24 hours with a comp-justified counter or acceptance, then close via Escrow.com with a registrar-to-registrar or push transfer. No brokers, no platform markup.
Will I own the domain outright after purchase?
Yes — fee-simple ownership. The domain transfers fully into your registrar account and you control DNS, renewal, and future resale from day one. No revenue-share, no licensing agreement, no name-back clause. Once the transfer is complete, it's yours outright.

.si Market Report — Q1–Q2 2026
The .si ccTLD just moved from $2,195 to $20,000 in under 12 months and is still invisible to DNJournal's Top 100.
NameIndex's original report documents the four documented comps, the compression thesis, and why the carry cost ($11/yr) makes this the most asymmetric bet on the agentic cycle.
