Who wins in consumer arbitration? Historically, this question has been nearly impossible to answer, as most arbitration proceedings are a private black box, and arbitral forums release only limited summary statistics. One exception is the Financial Industry Regulatory Authority (FINRA), which arbitrates virtually all disputes between investors and stockbroker-dealers, and makes all of its nearly 60,000 written arbitration decisions publicly available in an online database. This Article is the first to use computational text analysis tools to study these decisions, and to construct a measure of the claimants' win, loss, and settlement rates. It is the first installment in an original data analytics project that aggregates dispersed public data and document sets to assess the efficacy of arbitration outcome transparency as an investment protection measure. This Article makes three main contributions. First, the results of our novel study provide a more granular picture of customer experiences in the FINRA forum. We identify settlement as the most frequent outcome, followed by claimant losses, and then wins. In twenty percent of cases, we identify the presence of multiple outcomes per arbitration decision, where a claimant lost some claims but won or settled others, for example. This suggests a greater complexity and nuance in the notion of investor success than FINRA's monetary recovery versus no monetary recovery outcome measure--and previous scholarship--have recognized. Second, we discovered that the structure of FINRA's written arbitration decisions prevents further exploration of the amounts of compensatory damages that claimants recover, if any, compared to the amounts requested. Our final contribution is, therefore, a set of recommendations to FINRA--applicable to other private dispute resolution forums as well--to increase data access, usability, and transparency.
