Methodology (this batch)

BrokerMafia's September 2026 shortlists are editorial discovery tables ordered by public-fact criteria: regulatory tier (published register IDs), entity transparency, longevity or citable public scale, and product/authority clarity. BrokerMafia keyword-page presence is a tie-break only. We refuse paid rank, star scores, and copied review prose. Order can change when registers or public disclosures change — this batch is dated September 2026.

Scope: Primarily US broker-dealers with FINRA BrokerCheck paths. International multi-asset firms appear where publicly documented. Not crypto-only apps.

  1. Regulatory tier — published tier-1 register IDs where we can cite them.
  2. Entity transparency — can a reader match agreement → register row?
  3. Longevity / public scale — years, listing, or citable industry revenue lists.
  4. Product / authority clarity — FX entity vs exchange vs FMCSA broker vs DOI producer.
  5. BrokerMafia research presence — tie-break only.

Marketing claims (spreads, bonuses, pass rates, “best broker awards”) are labeled and never used as primary rank keys.
