Entity resolution and identity data infrastructure is one of the most heavily monetised categories we track inside ChatGPT answers, and the buying pattern inside it is unusual. Using our own daily multi-engine tracking, which includes ChatGPT ad tracking, we found a sponsored placement in 73.0% of the tracked answers we scored for this category, second only to waste and hauling software's 77.8% across the five categories in our wider study. What makes entity resolution different is not just the coverage number. Every single ad-bearing prompt we sampled was unbranded and purely informational: nobody typed a vendor's name and got served a competitor's ad. Buyers here are bidding on the research question itself, the "how do I evaluate," the "what is the difference between," the "how do I scale to," long before anyone has picked a shortlist. Arovy, LiveRamp, ZoomInfo, BigID, OneTrust, Armor, Auth0, Workday, Tonic AI and CData are all buying into that research phase, and the advertiser mix rotated hard mid month, evidence this is an active, churning auction rather than a handful of vendors sitting on fixed placements.
TL;DR
- 73.0% of tracked answers in entity resolution carried a sponsored placement (1,132 of 1,550), the second most heavily monetised of the five categories in our wider study.
- Every ad-bearing prompt we sampled was unbranded and informational. Buyers are bidding on research questions, not brand-name searches.
- The advertiser mix rotated mid month: Arovy led from 8 to 16 July, then disappeared entirely; LiveRamp, ZoomInfo, Armor and OneTrust rose from 16 July onward.
- The category leader's organic visibility rose from 3.9% (week commencing 25 May) to 20.9% (week commencing 20 July), a 5.4x increase across nine weeks, while the paid layer was building on top of it at the same time.
How heavily monetised is entity resolution compared with other categories?
Entity resolution and identity data infrastructure carried a sponsored placement in 1,132 of the 1,550 answers we tracked against its 11-platform category set (Data Ladder, Semarchy, AWS Entity Resolution, Tamr, Informatica, Splink, Quantexa, Reltio, Senzing and Zingg among them), a 73.0% coverage rate. Across the wider five-category study we ran using the same tracking, only waste, dumpster, septic and scrap hauling software monetised harder, at 77.8%. Every other category we measured sits far below both: finance automation at 7.1%, UK trades at 3.6%, London hospitality at 1.9%.
| Category | Value |
|---|---|
| Waste, dumpster, septic and scrap hauling software | 77.8% |
| Entity resolution and identity data infrastructure (highlighted) | 73% |
| London hospitality, wine bars and restaurants | 1.9% |
Both of the categories monetised this hard share the same structural feature: real annual contract value and a long buying cycle, the kind of enterprise purchase where a single click is worth a serious bid. Entity resolution is squarely that kind of purchase. It is infrastructure software bought by data, engineering and compliance teams, and 73.0% coverage means nearly three out of every four tracked answers in this category now carry a paid message alongside whatever the AI recommends organically.

Which prompts actually carry these ads?
None of the ad-bearing prompts we sampled named a vendor. Every one was a research question, the kind a buyer types before they know which vendor they want, not after.
- "Which entity resolution platforms scale to hundreds of millions of records in real time?"
- "Best entity resolution API for agentic AI applications in 2026"
- "What is the difference between cloud-native entity resolution and a third-party MDM?"
- "How do I evaluate entity resolution vendors for a regulated industry like banking?"
- "How do I give an LLM accurate customer data without hallucinations?"
That pattern matters more than the coverage number on its own. These are not "alternative to X" or "X vs Y" prompts, the kind of switching-intent query where a conquest ad against a named competitor makes obvious sense. They are the questions a buyer asks while they are still building the shortlist, and advertisers are bidding on that earlier moment in the funnel rather than waiting for a brand-name search to appear.
Which advertisers are buying entity resolution queries?
In the 30 answers we sampled, six advertisers accounted for most of the volume, with a long tail of one-off appearances behind them.
| Advertiser | Sampled appearances |
|---|---|
| Arovy | 6 |
| LiveRamp | 4 |
| ZoomInfo | 4 |
| BigID | 3 |
| Armor | 2 |
| OneTrust | 2 |
| Category | Value |
|---|---|
| Arovy (highlighted) | 6appearances |
| LiveRamp | 4appearances |
| ZoomInfo | 4appearances |
| BigID | 3appearances |
| Armor | 2appearances |
| OneTrust | 2appearances |
Behind that top six, a long tail of advertisers appeared once each in our sample: SheerID, Auth0, Salesforce (via MuleSoft), Workday, People Data Labs, Beacon.li, Sourcepoint, Form.io, Ours Privacy, Tonic AI, CompanyEnrich, CData and FreshBI. That is a wide field for a single category, spanning identity resolution specialists, data privacy platforms, HR and CRM vendors adjacent to the customer-data question, and B2B data enrichment tools. It reads less like a handful of entity resolution vendors bidding against each other and more like the entire customer-data and compliance stack treating "how do I resolve identity across systems" as a question worth buying into.
What do the ads actually say?
The verbatim ad titles lean hard into compliance and scale, the two anxieties that show up across the sampled prompts above.
- "Did IT approve this chat?"
- "AI-Powered Salesforce Data Dictionary"
- "#1 B2B Data. Use it anywhere."
- "LiveRamp | Best-in-class identity resolution"
- "Board-Ready Risk Reports"
"Did IT approve this chat?" is aimed squarely at the regulated-industry evaluation prompt above, a governance anxiety rather than a product pitch. "Board-Ready Risk Reports" targets the same buyer from the compliance angle rather than the technical one. None of the five verbatim titles we captured mention a competitor by name, which fits the unbranded prompt pattern: this is a category selling into a research moment, not fighting a head-to-head switching decision the way we saw in field-service categories elsewhere in our tracking.
Did the advertiser mix stay stable across the month?
No, and the shift was sharp. Arovy led the category from 8 to 16 July, then disappeared from our tracking entirely. LiveRamp, ZoomInfo, Armor and OneTrust all rose from 16 July onward, taking up the inventory Arovy had been holding. We are reporting this rotation as an observation from our tracking, not asserting a reason behind it. What it tells you is that this is an active, live auction with real churn inside a single month, not a small set of vendors holding fixed placements. Entity resolution ad presence itself has been continuous for longer than that single rotation, observed in our tracking as far back as 26 May, so the underlying auction has been running for at least two months; what changed on 16 July was who was winning it.
What's happening to organic visibility in this category at the same time?
While the paid layer above was rotating, the category's organic layer was moving too. The leading platform's organic visibility in entity resolution rose from 3.9% in the week commencing 25 May 2026 to 20.9% in the week commencing 20 July 2026, a 5.4x increase across nine weeks. We are not naming that platform here. The point worth taking from it is structural: in a category already carrying a 73.0% paid ad load, the organic layer underneath it is moving fast too, more than five times over in nine weeks, which means both the free and paid routes into this category's AI answers are shifting at the same time.
| Metric | Value | Caption |
|---|---|---|
| Week commencing 25 May 2026 | 3.9% | |
| Week commencing 20 July 2026 | 20.9% | |
| Rise across the nine-week window | 5.4x |
What does this mean for entity resolution vendors?
Three findings compound into one practical read. The category is monetised almost as hard as anything we track (73.0%, second overall in our wider study). Every ad-bearing prompt is unbranded, so the buying moment is research, not brand comparison, which means a vendor waiting to defend its own name in a "X vs Y" query is missing the point at which most of this budget is actually being spent. And the advertiser list rotates fast enough that a vendor absent from this month's answers is not necessarily out of the category permanently, the way Arovy's mid-month disappearance shows. It also echoes a pattern we measure at the opposite extreme: London hospitality carries almost none of this paid activity, at just 1.9% coverage, the category least worth an advertiser's money in the same study. See the full cross-category ad coverage study for how entity resolution's 73.0% compares against all five categories we tracked, including the two field-service categories where the buying pattern looks completely different, built on named competitor conquest ads rather than unbranded research questions.
