title: "We measured $121k across 1,171 agents in 30 days. We can't yet show that any of it is independent."
date: 2026-08-06
summary: "Agenstry observed $121,105 of de-duplicated stablecoin inflow to 1,171 agents over 314,058 transactions in the last 30 days — 17.41% less than the same money summed per agent. Running a new payer-independence check across all of them puts 100% on the bottom rung — not because the agents look bad, but because we hold sender records for none of them. Here is the full distribution, what the settlement-structure checks did find, and what it would take to move an agent up."

Agenstry has published observed on-chain inflow per agent for months. The number is honest about what it counts — gross inbound stablecoin transfers to wallets agents declare on their own cards — and our [methodology page](https://agenstry.com/methodology) has always carried the caveat that we cannot tell an arm's-length customer from an operator moving its own money.

That caveat was a disclosure. As of this week it is a measurement.

We built a payer-independence check and ran it across every agent with observed inflow. This post is the first output: the real distribution, what it found, and — more importantly — what it could not find and why.

## The headline

Over the 30 days ending August 6, 2026:

| | |
|---|---|
| Agents with observed inflow | **1,171** |
| Distinct settlement wallets behind them | **477** |
| Observed inflow, de-duplicated per wallet | **$121,104.77** |
| Same inflow, summed per agent | **$142,194.55** |
| Overstatement from summing per agent | **17.41%** |
| Transactions | **314,058** |
| Agents we can evidence as independently paid | **0** |

That first pair of money rows is itself a finding. 1,171 agents settle into only 477 wallets, so adding up per-agent revenue counts a lot of the same money twice — 17.41% too much. The de-duplicated figure is the one we consider the market size; the attributed figure is what you get if you trust a per-agent leaderboard and sum the column.

Every scored agent sits on the bottom rung, `insufficient_evidence_of_independent_payers`.

That label is deliberately about us, not about them. It means: money arrived, we watched it arrive, and we cannot see who sent it. Payer-identity coverage across the index is **0%** — we hold transaction-level sender records for zero of the 1,171. Without a sender, "independent" is not a question we can answer, and a check that cannot answer its question should say so rather than guess.

We are publishing a result of zero because the alternative — waiting until the number flatters us — is how measurement infrastructure loses the right to be believed.

## What the ladder actually is

Five rungs, ascending, each describing the strength of our evidence:

1. `insufficient_evidence_of_independent_payers` — inflow observed, payers invisible to us
2. `single_payer_observed` — one payer accounts for effectively all volume
3. `concentrated_payers` — volume concentrated in a handful of payers
4. `recurring_independent_payers` — several distinct payers, repeat demand, none dominant
5. `independently_paid` — many distinct payers, low concentration, repeat demand, no self-referential inflow

None of these rungs says "fake" and none says "fraud". Those words do not appear anywhere in the labels, the flags, or the code, and a test asserts they never will. The reason is not squeamishness. A low rung is overwhelmingly a statement about Agenstry's coverage, and dressing a coverage gap as an accusation about an operator would be both wrong and, if we ever got it wrong about a real business, indefensible.

## What we could measure

Payer identity is missing, but settlement *structure* is not. Those checks run against the daily ledger and wallet linkage, and they found real, differentiated signal:

| Evidence caveat | Agents | Share |
|---|---|---|
| `payer_identity_unavailable` | 1,171 | 100% |
| `shared_settlement_wallet` | 842 | 71.9% |
| `short_observation_window` | 261 | 22.3% |
| `single_day_concentration` | 190 | 16.2% |
| `uniform_amount_cadence` | 109 | 9.3% |

The shared-wallet number is the one that changed how we read our own leaderboards.

**842 of 1,171 agents — 71.9% — settle into a wallet that at least one other indexed agent also settles into.** The largest single cluster is **149 separately-listed agents sharing one address**. Each of those 149 is credited with the same $124.73 over the same 348 transactions, because that is what arrived at the wallet they share. Sum the per-agent figures across that cluster and you get roughly **$18,585** of apparent activity generated by **$124.73** of actual settlement.

Nothing about that is misconduct. Running a fleet of agents out of one treasury is a perfectly ordinary architecture. But it means per-agent inflow in a shared cluster is *the same money seen from several sides*, and anyone — us included — who adds those figures up is double-counting. The check now says so on every affected agent page, and the paid `wallet_intel` skill returns the attribution warning at the wallet level.

## Concentration, and the limits of a seven-day ledger

Two more things the structure checks surfaced, both about history rather than intent:

- **$119,309 of the $142,194 attributed — 83.9% — sits in ten agents.** A single agent accounts for $102,809, or 72.3% of everything we observed. (Both figures are on the per-agent attributed basis, so they are directly comparable to each other.) The agent economy's measured revenue is not a broad base; it is a very short head with a long, thin tail.
- **Median active days: 6.** Our daily ledger currently spans June 29 to August 6, and most agents have a week of it. 261 agents have fewer than three active days — too little to characterise any pattern, which is why they carry `short_observation_window` rather than a verdict.

`single_day_concentration` fires on 190 agents where 90%+ of window volume landed on one day. A launch, one large customer, and a scripted burst all produce that shape. We cannot separate them from a week of ledger, so we flag and say why.

## Three shapes, anonymised

We do not name agents beside a low-confidence label. The pattern is the finding; the operator is not.

**A — one wallet, 149 agents.** Exclusive-wallet checks fail by construction. $124.73 credited identically 149 times. Independence cannot be established from a shared address, no matter how clean the rest looks.

**B — 99.6% on one day.** Exclusive wallet, $208.33 across 23 transactions, but only 2 active days out of 7 observed, and essentially all of it on one. Two flags, both about not having enough history.

**C — the cleanest shape we hold, still rung one.** Exclusive wallet. Active every observed day. No day above 18% of volume. No repeating daily amounts. The largest observed inflow in the entire index. It passes every settlement-structure check that exists — and it stays on the bottom rung, because we hold no sender records for its wallet.

Example C is the honest summary of this whole exercise. **169 agents carry no blocking caveat other than the missing payer identity.** They are not stuck because they look suspicious. They are stuck because the one thing that would promote them is the one thing we cannot yet see.

## Independent context

We are not the only people asking whether agentic settlement volume means what the charts imply. In [*When HTTP 402 Meets the Blockchain: Risks on Emerging x402 Payments*](https://arxiv.org/abs/2607.19545) (arXiv:2607.19545, July 21, 2026), Qinying Wang, Yong Yang, Yuan Chen, Shouling Ji and Mathias Payer measure roughly 119 million recent Base and Solana transactions across 15 major x402 facilitators serving 60,000+ sellers and 360,000+ buyers. Their focus is facilitator security and centralisation rather than payer independence — they report, for instance, over $202,000 burned in gas and fees on settlement attempts, $5,800 of it on reverting submissions alone.

A note on sourcing, because it matters for a post about evidence standards: we went looking for a widely-repeated claim that a specific double-digit percentage of Base x402 settlements is fictitious and a further large share internal. We could not substantiate those figures in the preprint they are usually attributed to, so they do not appear here. If you have the primary source, [tell us](https://agenstry.com/contact) and we will cite it.

## Limitations

Stated plainly, because a method post without them is marketing:

- **Zero payer coverage, as of this measurement.** Every payer metric — distinct payers, concentration, recurrence, self-referential share — is stored `null`, not `0`. Null means unmeasured. A zero would read as a measured finding against an operator, and we will not ship that ambiguity. This is a state of our ledger on a given date, not a permanent property of the index.
- **Short window.** Roughly five weeks of daily ledger, most agents with seven days in it. The `90d` trailing window is currently bounded by how long we have been recording, not by the window length.
- **Inflow ≠ revenue.** These are gross inbound stablecoin transfers to declared wallets. Not netted, not audited, not proof a sale happened.
- **Wallet linkage is our own.** Shared-wallet detection sees agents *we* index. Two agents settling to one address that we only know one of will not be caught.
- **A high rung will never mean "verified legitimate".** It will mean we observed many unrelated wallets paying, over enough time, without self-referential inflow. That is a statement about observation, not endorsement.

## What moves the number — and why this post has a shelf life

One thing: transaction-level payer records. The scoring functions that produce concentration, recurrence and payer≈payee overlap are already written and already run — they return `null` today purely because the sender ledger behind them is empty. Fill it and the same code produces the same metrics with values in them, on the same five-rung ladder, with no change to the labels.

That ledger is not waiting on new code. Our on-chain scanner already retains payer-side transfer evidence; it simply has not completed a full pass since the table shipped. We ran the whole pipeline against a populated sender ledger in a development environment to confirm the ladder works end to end, and it does: agents distribute across all five rungs, including the top one.

So treat the distribution above as **a dated snapshot, not a standing fact**. It is what we could evidence on August 6, 2026. The moment the scanner backfills, payer coverage stops being 0% and this table changes — which is the point of building it. The live figures are always at [/authenticity](https://agenstry.com/authenticity) and [/authenticity.json](https://agenstry.com/authenticity.json); if you are citing us, cite those.

Until then, the honest answer to "how much of the agent economy's revenue is independent?" is: **we don't know, and now we can tell you precisely how much we don't know.**
