EMMA in the Future
The MSRB established the EMMA website in 2008 to provide retail investors with centralized, online and free access to municipal securities market disclosure documents and transaction pricing data on a real-time basis. Given the market’s enthusiastic adoption of EMMA, the website now serves not only retail investors but all market participants, including municipal entities, dealers, municipal advisors, institutional investors and the public. In recognition of EMMA’s broader market utility, the MSRB seeks to provide all market stakeholders with access to data, documents and tools that support fair transactions, facilitate decision-making and promote an efficient municipal securities market. Evolving EMMA into an industry-leading platform that meets the needs of market participants requires establishing appropriate guiding principles for future functionality, promoting and enhancing use of EMMA as a tool for satisfying regulatory objectives, and improving the overall user experience of the website.

What Is EMMA Dataport?
Municipal securities dealers, municipal advisors, issuers, obligated persons and their designated agents provide the MSRB with electronic documents to be posted on EMMA. EMMA Dataport is the utility through which documents and related information are submitted. To submit documents, users should access the EMMA Dataport link at the top of the EMMA homepage. There, users will also find helpful information on making submissions, including system documentation and user manuals.
