Gaming Laboratories International (GLI) has released the final published version of the “GLI-33 Standards for Event Wagering Systems V1.1,” for use by the sports wagering industry, coinciding with the one-year anniversary of the fall of the Professional and Amateur Sports Protection Act (PASPA).

According to press materials, GLI-33 V1.1 reflects a revision to the core event wagering standards to provide better clarity between technical requirements which would be evaluated in the lab and operational controls and procedures, which would be evaluated on-site post system install. Additionally, this revision enhances sections pertaining to operational controls and procedures, including periodic security testing to help regulators and operators create more efficient and alternative processes for monitoring sports wagering operations. In general, the changes are largely designed to improve the clarity and consistency of requirements.

Multiple tribal and state regulators have already adopted and/or accepted certification to GLI-33 standards including Mississippi, West Virginia, Rhode Island, Washington DC, and the Cherokee Tribal Gaming Commission of North Carolina.

Translated versions of the GLI-33 V1.1 standard will be made available in the near future. These translated documents will be posted to the GLI public internet site for global consumption.

Each standard in the GLI Standard Series is a culmination of industry best-practices and is continually updated based on industry feedback.  The GLI Standards are true “industry standards” in that they are created using a collaborative approach which involves thousands of gaming industry stakeholders.  These standards are intended to assist regulators by creating baseline technical guidelines which they can adopt and/or utilize in the manner they see fit.  In addition to assisting regulators, the standards are of tremendous value to suppliers who use the standards as a guide in their design and development process, saving both time and expense.

The sports betting market by 2023

The chart here, from Eilers & Krejicik Gaming, represents their latest baseline estimates for the total annual revenue that regulated sports betting would generate in the U.S. through 2023. The projection assumes 36 states and Washington, D.C. authorize sports betting by 2023, and that those states vary on key policy terms such as tax rate, license fee, availability of licenses and the ability to offer sports betting online.
