If you’re headed into a FINRA arbitration, one of the most important parts of the process arrives before anyone testifies, before documents are argued over, and well before a final award is issued: arbitrator selection.
That’s because the arbitrators are the people who will hear the evidence, evaluate credibility, interpret the rules, and decide the outcome. In practical terms, panel composition can shape how the case feels, how the hearings are managed, and how certain facts land in the room.
For many investors and industry professionals, this stage feels technical and easy to overlook. It often comes wrapped in lists, classifications, deadlines, disclosure reports, rankings, and strikes. But the process is more structured than it first appears, and FINRA publishes detailed rules explaining how it works. In this post you’ll learn who FINRA arbitrators are, how the lists are generated, what “public” and “non-public” mean, how striking and ranking work, what disclosures matter, and why many parties spend so much time evaluating the people on the lists.
If you want a broader overview of how panel makeup can shape the case from the very beginning, this topic fits into that larger conversation.

FINRA arbitrator selection is the process by which the parties in a FINRA arbitration choose the neutral decision-makers who will hear and decide the dispute. FINRA administers the forum, but it states that it has no part in deciding the award; the decision belongs to the arbitrator or panel selected through the rules-based list process outlined in the FINRA Code and related guidance (FINRA arbitration process, decision and award).
In customer cases, FINRA uses a list selection algorithm that randomly generates lists from its arbitrator rosters for the selected hearing location. The parties then choose their panel through a process of striking and ranking the names on those lists (FINRA Rule 12400).
This tends to be one of the first points in the case where strategy becomes very real. A file may look strong on paper, but different arbitrators may bring different professional backgrounds, management styles, and levels of familiarity with certain products or disputes.
FINRA arbitrators are individuals on FINRA’s roster who have completed the application process, passed a background check, been approved through FINRA’s roster process, and completed required training (How parties select arbitrators).
FINRA explains that its system includes approximately 7,000 arbitrators qualified to hear cases, and the Neutral List Selection System randomly generates lists from that roster (Investor’s Guide to Securities Industry Disputes).
The parties do not choose from a blank slate. Instead, FINRA sends identical lists to both sides, along with an Arbitrator Disclosure Report for each candidate. FINRA describes that report as resembling a résumé and says it includes employment background, education, and training (FINRA arbitration process). FINRA’s ethics materials also explain that the disclosure report is based on the arbitrator’s application and is central to informed selection decisions (FINRA Arbitrator Ethics).
These classifications matter because they affect which lists are sent and which roles an arbitrator may fill.
In general terms, a public arbitrator is someone who is not classified as having the kinds of securities-industry ties that would place them in the non-public category. In a single-arbitrator customer case, the arbitrator will be a public arbitrator (SEC Investor Advisory Committee recommendation discussing FINRA rules, FINRA Rule 12402).
A non-public arbitrator generally has industry-related experience or affiliations that place them in FINRA’s non-public classification. In three-arbitrator customer cases, FINRA still sends a non-public list as part of the selection process unless the list is effectively eliminated through the parties’ strikes under the rule structure (FINRA Rule 12403).
