Gaming Laboratories International (GLI®) Releases Draft Event Wagering Technical Standard for Industry-Wide Comment

Significant Regulator, Operator, and Supplier Demand for Sports Betting Technical Standard Culminates After a Year-Long Process of Analysis and Collaboration

LAKEWOOD, NJ (June 5, 2018) – After more than a year of working closely with domestic and international gaming stakeholders, Gaming Laboratories International (GLI®) announced that it has released its longawaited draft technical standard specifically for event-wagering operations. “GLI-33: Event Wagering Systems” is a technical standard produced by GLI for the purpose of providing independent technical analysis and/or certifications to wagering industry stakeholders wishing to represent compliance for their wagering operations and systems. 

GLI Responds to Significant Demand

More than 12 months ago, U.S. state regulators, sports betting operators, sovereign tribal nations, lotteries, and industry suppliers across the country began asking GLI to establish a clear and cohesive technical standard for sports/event wagering systems designed to help them regulate and/or implement legal wagering on sports and other events. Responding to this stakeholder demand, GLI spent approximately one-year formulating GLI-33, which was submitted for industry-wide comment via an advisory notice on May 18, 2018. 

GLI Leverages Decades of Global Sports Betting Experience

Leveraging its decades of extensive global sports/event wagering experience throughout markets in Australia, Europe, Africa, Latin America, Canada, and the U.S. (Nevada), GLI’s global team of sports betting experts has been working closely with industry stakeholders across the country to help prepare them for the expansion of regulated sports betting in the U.S. These types of industry collaborations are immeasurably valuable for the industry as they allow interested parties to guide technical standardization across the industry.  

“As the first and most experienced independent event-wagering testing and certification lab in the world, we used our nearly 30 years of global sports-wagering experience to develop GLI-33, the world’s first event-wagering standard that can be effectively deployed by jurisdictions across the U.S. to ensure the integrity of the country’s dramatically expanding sports betting opportunities,” stated James Maida, President and CEO of GLI. 

“We are gratified that so many gaming authorities, operators, and industry suppliers across the country reached out to GLI as their essential technical partner to cooperate in developing this new technical standard for event wagering,” Maida added. “Thanks to this extensive and close collaborative effort, the draft GLI-33 standard offers a starting point for clear guidance regarding betting integrity and a way to move forward responsibly in the wake of the U.S. Supreme Court’s recent ruling striking down the Professional and Amateur Sports Protection Act (PASPA). We encourage broad participation as we refine this extensive document into a useful template for the U.S. market.”

GLI-33 Public Comment Period Concludes June 8, 2018

The draft of GLI-33, which is available at, is being provided to gaming and lottery regulators, suppliers, test laboratories, operators, industry trade associations, and other key stakeholders for review and comment for a limited time. Written comments are encouraged and can be submitted to GLI upon review of the linked PDF copy of GLI-33 provided here. The formal comment period began with the issuance of the GLI-33 Advisory on May 18, 2018, and concludes in three weeks from that date, on June 8, 2018. Comments should be submitted to the “GLI Compliance” mailbox at

GLI Standards Are the World Standard 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.
