GLOBAL TRADER RANKINGS / RECORD COMPARISON
Ken Griffin: source-backed profile, no global rank
Citadel leadership without conflating investment management and market making
Citadel identifies Kenneth C. Griffin as its founder and chief executive and separately describes his role at Citadel Securities. These named organisations and roles should not be collapsed into one performance object.
Citadel and Citadel Securities have distinct boundaries
A market-making business and an investment-management business are not the same portfolio. A fact about one organisation does not establish a return for the other. Preserve the exact entity label in the claim register. The shared individual is a connection between biographies, not permission to merge their economics or their regulatory source records.
Institutional scale does not provide a return denominator
A headline capital figure can describe an organisational measure as of a specific date. It is not automatically opening equity for a performance calculation, a personal fortune or a risk-adjusted score. The current profile does not reproduce changing capital figures because its question concerns role attribution and the missing account boundary.
No reconstructed personal performance table
This publication has no primary personal-account ledger or defined fund-class series for a global comparison. The previous exact ranking and numerical factors remain withdrawn. An official leadership source supplies useful identity context while the cost, currency, interval and risk-path fields remain unresolved for any proposed performance ordering.
Comparison fields and permitted use
The identity source and the numerical comparison question are separate. Store the measured object, observation dates, currency, expense definition, valuation frequency and original population before assigning any performance order. No missing field is replaced by an industry average or a plausible factor estimate. The role profile can be cited within its stated scope; the retained historical correction remains applicable to the old numerical claims.
A practical research route
Open the linked original source and identify the sentence supporting the role. Then inspect any proposed financial document independently: which legal vehicle or account does it describe, and which period does it cover? A present-day affiliation cannot retrospectively establish who controlled every earlier trade. If the source cannot answer the comparison question, keep a qualitative profile and disclose that limit rather than inventing an ordinal position.
Original references and scope

9 October numerical correction retained
Ken Griffin: source record pending
Correction, 9 October 2026: the former global placing, composite and factor scores, estimated capital and per-year return table are withdrawn. Primary per-trader source records were not supplied, so those numerical comparisons cannot be reconstructed.
What this retained route means
This is a source-status placeholder for the archived name Ken Griffin, not a verified biography, independently audited profile or current ranking. It is excluded from indexing while the underlying evidence is unavailable. Retaining the route makes the correction visible to readers following an older link; it does not establish the identity or achievements previously attributed here.
Evidence required for a substantive profile
Supply an official identity or organisation source, the exact account or fund object, covered dates, currency, costs and a direct performance publication where a numerical claim is proposed. An account, fund, competition and personal record must remain separate. Generic mentions of filings, press coverage or audited statements are not a substitute for the actual linked and dated records.
No replacement numerical finding
Missing evidence is not proof of poor performance or misconduct. This correction withdraws the publication's unsupported calculation rather than making a new allegation about the archived name. No rank or score is assigned from reputation or guessed inputs. Read the comparison-cohort protocol and inspect return-period arithmetic without treating either as independent trader validation.
