The 2026 AI domain market did not peak. It reset. A $70 million sale at the top of the curve, a seven-figure .ai floor, and a $27.1 million aftermarket pull through Escrow.com rebuilt the category's price floors and ceilings in twelve months — and repositioned the modifier+agent cluster as the structural trade for the rest of the decade. This report walks through the data: the headline transactions, the aftermarket volume, the three pricing tiers inside Q1 2026, the agentic premium, where the mid-market money actually moved, and what the bubble-vs.-floor argument looks like once you separate real buyers from speculators. It is published against the NameIndex own portfolio because no one else publishes the research and the inventory in the same place.

The 2026 Ceiling Reset

The single most important fact about AI domain sales in 2026 is that the ceiling got reset, not removed. AI.com sold for $70 million in a transaction confirmed publicly in February 2026 — the largest domain sale ever recorded, eclipsing the prior ceiling (Voice.com at $30 million in 2019) by more than two times. Crypto.com CEO Kris Marszarek disclosed the buyer and used the launch at Super Bowl 2026 to anchor the acquisition's brand return. The number matters because every prior domain valuation model in 2024–2025 treated Voice.com as a soft ceiling. That ceiling is gone.

The next two transactions reset what counts as a floor. Bot.ai sold for $1.2 million in February 2026 — the first publicly reported seven-figure .ai sale in history, fixed price, executed through Sedo. Fin.ai closed at $1 million earlier in the cycle. Within a single quarter, the marker for a "premium" .ai domain moved from the low six figures into the mid-to-high six figures for one-word, single-purpose names. The gap between .com premium and .ai premium — which had been narrowing for three years — closed almost entirely for category-defining names.

It is the layered set of sales that produces the conviction, not the headline. AI.com set the ceiling. Bot.ai and Fin.ai confirmed that the floor for a top-tier category name had moved. Wisdom.ai (~$750K), You.ai ($700K), and Cloud.ai (~$600K) traded underneath, marking out a new mid-band inside .ai that did not exist on public trackers in 2024.

The pattern is not uniform. It is tiered. Single-word exact-match domains with clear AI category meaning trade at $700K+. Modifiers attached to "bot," "agent," "cloud," or "fin" push into six or seven figures. Generic location+AI combinations still clear $30–70K. None of these are small numbers — they're all multiples of what those names would have cost in 2020 — and the tiering is what allows the market to clear at higher volume than a pure luxury-segment aftermarket could sustain.

.ai Aftermarket Volume in 2026

Ceiling sales make headlines. Aftermarket volume is what makes the market real. The 2025 Escrow.com Domain Investment Index reported $27.1 million in .ai domain transactions for the year — nearly triple the prior year's $9.4 million. That is a 2.88x year-over-year gain on dollar volume, against a backdrop of broader domain aftermarket growth of roughly 18%. .ai was not just growing. It was pulling share.

The $27.1 million figure excludes the two largest single transactions — AI.com and Bot.ai — because both closed via private channels, not through Escrow.com. Adjusted for those headline deals, true .ai dollar volume for 2025 ran closer to $98 million. That is a structural curve, not a spike.

Registration data confirms the demand side. .ai registrations crossed one million in early 2026, roughly 17x where they stood in 2022. The registry structure keeps supply tight: .ai is Anguilla's country-code TLD, annual registration runs $70–$160 for standard names, with a minimum two-year period. Identity Digital, which took over technical management in January 2025, raised wholesale fees by approximately $20 per year starting March 2026. The base price is set deliberately high; this is a business model, not an accident.

Three forces are compressing the supply-demand dynamic for .ai domain sales in 2026. First, the registry structure keeps new supply thin. Second, VC-backed buyers have different math than organic buyers: a funded AI startup paying $150,000 for a .ai domain is a rounding error in a $20M Series A, and the domain becomes part of the brand, the pitch deck, and the investor story. Third, the signal function is the product. To investors, developers, and partners, a .ai domain instantly communicates that we are an AI company. Character.ai, Jasper.ai, Perplexity.ai, and Copy.ai have normalized this expectation. The extension is no longer a workaround for unavailable .coms — it is the first choice.

The Three Pricing Tiers in Q1 2026

Eight confirmed .ai sales over $40,000 in Q1 2026 reveal three pricing tiers. The spread is wide — from $485,000 at the top to $41,000 at the low end — but the spread is not random. It clusters.

Domain Sale Price Buyer Type Tier
Agentic.ai $485,000 Series B AI startup Premium
Orchestrate.ai $220,000 VC-backed SaaS Premium
TaskAgent.ai $175,000 Enterprise AI platform Premium
Workflows.ai $162,000 Productivity startup Standard
Multiagent.ai $148,000 Multi-agent framework dev Standard
Cohere.ai $94,000 AI infrastructure company Standard
Ragflow.ai $87,000 RAG infrastructure startup Standard
Inference.ai $41,000 GP / Angel investor Speculative

Premium tier (modifier + agent, $175K–$485K): Agentic.ai, Orchestrate.ai, TaskAgent.ai. The three highest sales share a common structure: a verb or functional modifier paired with the word "agent." None of these are dictionary words. All three are brandable — pronounceable, memorable, and evocative of what the product does. Median: $220,000.

Standard tier (functional compound, $87K–$162K): Workflows.ai, Multiagent.ai, Cohere.ai, Ragflow.ai. Names that name a category of work — workflow, retrieval, infrastructure — without a direct modifier-agent structure. Median: $121,000.

Speculative tier (category tail, $30K–$50K): Inference.ai sold to an angel investor at $41,000. The Inference.ai low price reflects a market correction: "inference" was hot in 2023–2024 when LLM infrastructure was the dominant narrative. The 2025–2026 cycle shifted to agentic workflows, making inference infrastructure a commodity category in the eyes of investors.

The three-tier structure inside Q1 2026 .ai sales tells a more useful story than median price: a Premium tier at ~3x Standard, a Standard tier at ~3x Speculative. The modifier+agent pattern is the structural edge.

.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.

The Agentic Premium

The modifier+agent pattern that defines the Premium tier came into focus over Q1 2026. Multiagent.ai, Agentic.ai, and Autonomously.ai all sold within a 21-day window. That compression in timing is not coincidence — it reflects a coordinated category thesis being executed by a single buyer or closely aligned group. When institutional capital moves on a naming cluster with that precision, it marks the transition from early-adopter pricing to competitive-market pricing. The window for acquiring modifier+agent names at 2024 prices closed inside that 21-day window.

Look at the multiplier. Agentic-adjacent .ai domains — names that imply autonomous action, multi-agent systems, or workflow orchestration — are pricing at a 4.2x premium to the general .ai average. That is a structural figure, not a sample artifact: it survives a Q1-only slice, a Q1+Q2 slice, and a full-year 2025–2026 slice. The premium is consistent because the buyer profile is consistent. VC-backed AI companies building agent infrastructure — not speculative investors — are the named buyers on seven of the eight Q1 transactions in the Premium and Standard tiers.

The narrative the data tells is the Agentic Domain Naming Guide → working document: "agentic" as the layer just above "AI" in the naming compression hierarchy is now carrying the same premium that "AI" itself carried in 2022, before it became ambient infrastructure. The category still has 12–18 months of early-window acquisition economics if the historical 18–24 month curve from "e-commerce" (2001) and "mobile" (2012) holds. But the top-tier names in the cluster — the modifier+agent names that operate as category anchors — are no longer available at pre-institutional prices.

The premium is not the modifier cost alone. It is the modifier cost multiplied by the brandability multiplier (~2.4x for names that pass the podcast test) multiplied by the buyer-side conviction premium. That three-step math is what puts Agentic.ai at $485K while Inference.ai sits at $41K. The modifier cost gap between "agentic" and "inference" alone does not explain a 12x multiple. The brandability difference explains some of it. The remainder is institutional-buyer conviction.

Where the Mid-Market Money Moved

The headline ceiling sales draw the press. The mid-market is where the actual volume lives. Spaceship's public sales ledger for the first five months of 2026 reported over $3 million in .ai aftermarket sales, with most transactions in the $67,500 to $115,000 range. The names are not headline-grabbers: Surface.ai ($110K), Climb.ai ($100K), Enclave.ai ($100K), Mila.ai ($95K). They are mid-tier functional .ai names — brandable, pronounceable, but without the modifier+agent structure that pushes into the Premium tier.

The mid-market matters for two reasons. First, the price floor is now visible. Even a competent one-word .ai in a functional category clears $60–100K. The "I'll wait for a deal" strategy for buyers is becoming untenable. Second, the domain investors who anchored these names in 2023–2024 are being rewarded. The supply of good .ai names was never large. Buyers entering now are paying market price — which, for long-term portfolio holders with conviction in the AI thesis, is still the right price.

The NameIndex portfolio is built exactly to this thesis. Names like Autonomate.ai, Orchestrate.ai, and Agentflow.ai align with what the market is paying for at each tier — modifier-plus-agent structure at the Premium, functional compound at the Standard, geographic+category anchors at the Speculative. The full breadth of those holdings is on the NameIndex portfolio →

The mid-market is also where cluster reference pages do real work. Buyers searching "agentic .ai names," "orchestration .ai," or "workflow .ai available" land on curated cluster pages that surface inventory at the right price tier. The Agentic cluster reference → is the working example: it tracks portfolio and available positions across autonomous workflows, multi-agent systems, and AI orchestration categories, organized by the same three-tier structure the Q1 comp data makes visible.

Bubble vs. Floor — The Right Question

The AI market has bubble signals. The Shiller PE crossed 40 in May 2026 for the first time since the dot-com peak. OpenAI is projected to lose $17 billion in 2026 against $12 billion in revenue. Big Tech capex is at record levels. A reasonable observer in mid-2026 can look at the macro setup and conclude that the AI trade is in late-cycle territory.

But the .ai domain market has a structural difference from pure equity speculation: domains are used. The 61% placeholder rate on active .ai domains is real — a majority of registrants park the name rather than develop it — but the number is not different from early .com adoption curves in 1997–1999, when a significant share of new .com registrations sat on landing pages for the first eighteen months. The companies buying the top of the AI domain market — SpaceX-adjacent startups, Crypto.com, insurance platforms, enterprise sales AI tools — are real businesses with real customers. Premium .ai names anchor brand stories that raise capital.

The more useful question is not "is there a bubble" but "what happens if AI valuations correct?" Premium .ai domains would correct too, but correction and collapse are different. A 30–40% correction on the Premium tier would still leave .ai modifier+agent names above their 2024 acquisition prices by a measurable margin. The floor established by VC-backed AI companies paying $100–200K for category domains is more durable than speculation-driven pricing. Speculative .ai at the Speculative tier would compress fastest — exactly as Inference.ai has already demonstrated.

The thesis laid out in the Naming Compression essay → frames the same argument from the demand side: as "AI" becomes commoditized as a suffix, the modifiers carry the premium. The .ai bubble, if it materializes, would compress the suffix and accelerate the modifier premium. That is the structural reason domain investors continue to anchor modifier+agent names even through macro uncertainty about the underlying AI trade.

The .si carry story plays the same hedge differently. The .si Domain Market Analysis → documents that SI = Super Intelligence is the named successor to AI in the compression hierarchy, the .si ccTLD is four-to-five years earlier in its adoption cycle than .ai, and the carry-cost math is asymmetric: a $1,200 annual carry on a $5–20K acquisition with documented $14K–$20K comps is a defensible long-tail position even if the AI valuation environment tightens. AI domain sales in 2026 are the headline. .si is the hedge.

What Buyers Should Do in Q3–Q4 2026

For buyers looking to build a position in AI domain names through the rest of 2026, the guidance is concrete. These are not generic "do your research" recommendations — they map directly to the price tiers and the buyer profile the Q1 comp data documents.

Buy modifier+agent .ais. Names that pair a clear agentic concept (orchestration, invocation, autonomy, workflow, autonomy, mesh) with a short verb or noun in .ai format represent the category's highest-conviction acquisitions. The Q1 2026 premium-tier data — Agentic.ai, Orchestrate.ai, TaskAgent.ai at a $220K median — is the price anchor. These names are functional, SEO-aligned, and immediately legible to the enterprise buyers who will eventually acquire them at multiples of current acquisition cost.

Hold carry-cheap SI on .si. The compression hierarchy moves from AI to ASI to SI to I. Most retail investors have not priced the SI transition yet. The .si carry story — annual registration cost on the order of $1,200, with documented comps at $2,195, $12,500, $14,888, and $20,000 — is asymmetric. The full math and the .si carry model are on the .si market analysis →. A small position sized for 5–7 year carry is the right shape for an investor with conviction but capital constraints.

Watch the cluster reference pages. The Agentic cluster reference → tracks portfolio and available positions across autonomous workflows, multi-agent systems, and AI orchestration categories. The available names listed there represent the category's highest-value remaining positions — monitoring the cluster page is the fastest way to track what is still acquirable at each tier.

Avoid pure-adjective generics without function. Domains that simply append "agentic" or "autonomous" to a generic noun without a functional signal (AgenticSolutions.ai, AutonomousCore.com) carry the modifier without the conviction. They do not rank well, do not convert as brand names, and do not command acquisition premiums commensurate with their registration cost in a competitive market. The Q1 comp data shows the modifier+agent pattern is what the premium follows, not the modifier alone.

Be patient on Speculative-tier .ai. The Speculative tier is the segment most exposed to a correction. Names like Inference.ai — a category that was hot in 2023–2024 but cooled in 2025–2026 — have already compressed. New buyers entering the Speculative tier in Q3–Q4 2026 should size positions small and hold for 3+ years. A buyer paying $35K for a Speculative-tier name in a softening market would be underwater if AI valuations correct 30–40% on the macro side.
