title: "Every located instance of FICO's 'majority of world card transactions' figure traces back to FICO's own self-reported statistics, with no independent audit found"
type: "observation"
status: "seedling"
audit_status: "capture-verified — synthesis across the Tier 1–2 documents read directly this session (the 2008 10-K, the 2021 press release) plus the Tier 3 source already recorded in [[claim-hnc-falcon-fraud-manager-became-fico-infrastructure]]; no additional source beyond those. This is a negative finding (no independent corroboration was found), not a positive claim that none exists — coverage of decades of FICO marketing and filings via search-and-read is imperfect. | AUDIT 2026-08-08 (opus-5, cross-model): the negative finding was re-tested rather than taken on the note's word, and holds — a fresh search for an independently audited market-share figure for Falcon's share of world card transactions returned only FICO's own materials, vendor-analytics aggregators reselling install counts, and the Siegel piece; no market-research, regulator, or competitor measurement surfaced. Two corrections applied to the enumeration. The 2008 anchor was re-read in full (extract_pdf, sha matching) and the 2021 release re-fetched. The 'two-thirds' item counted here as two occurrences — the Machine Learning Times reprint and a European Business Review excerpt — is one Eric Siegel text at two venues, per a direct fetch of both URLs; the body now says so, and the concentration is therefore tighter than the note originally claimed, not looser. The `[unverified-quote — needs direct read]` character of the Siegel wording is unchanged: it was located through a page-rendering fetch, not a read of *The AI Playbook* itself, so it carries no weight beyond attesting that the sentence circulates."

Every occurrence of the "majority"/"two-thirds" transaction-share statistic
located across this research — Fair Isaac's FY2008 Form 10-K
([[claim-fico-2008-10k-states-falcon-used-in-65-percent-of-credit-card-transactions]]),
a 2021 FICO press release
([[claim-fico-two-thirds-figure-denominator-drifts-across-restatements]]),
the Machine Learning Times / Predictive Analytics World item already in the
vault ([[claim-hnc-falcon-fraud-manager-became-fico-infrastructure]]) — which
a 2026-08-08 fetch of that URL identifies as a November 8, 2024 republication
of Eric Siegel's March 21, 2024 *European Business Review* piece, itself
excerpted from his *The AI Playbook* (MIT Press, February 2024), so what this
note originally counted as two secondary occurrences is one text by one author
at two venues — and current-era FICO marketing copy: all of it resolves, when traced
upstream, to Fair Isaac/FICO's own disclosures about its own product.
No independently audited market-share study, competitor teardown, or
regulator's figure corroborating the transaction share was found this
session. The outlets repeating the figure are re-quoting FICO, not measuring
FICO: a single-source-concentration situation in substance, even where the
wording has been repeated by many secondary venues over nearly two decades.
The repetition is narrower than a venue count suggests — one of the two
apparently independent secondary occurrences turns out to be the other one
republished, and Siegel's own wording — "That's two-thirds of the world's
cards," carried as `[unverified-quote — needs direct read]`, located through a
page-rendering fetch rather than a read of the book — is a third denominator
again: cards, not accounts and not transactions.

This is an argument from absence and is recorded as such — this session did
not read every FICO annual report between 2008 and the present, nor every
market-research or competitor analysis of the card-fraud-detection industry
that might exist. What can be said is that no such corroboration surfaced
across a genuine multi-document search this session, which is evidence the
figure is not prominently independently audited, not proof that no audit
exists anywhere.
