Companies involved in Massachusetts’ budding sports betting market are already starting to seek out deals and partnerships with each other in the run-up to the scheduled launch of sports wagering early next year, according to new documents regulators released to MassLive and interviews with key stakeholders.

Public details are still scarce, but a handful of indicators of potential partnerships are emerging in surveys that sports wagering hopefuls were required to turn in to the Massachusetts Gaming Commission last month as part of the sports betting application process and in discussions with industry experts.

The surveys ask for basic information from those looking to apply for a sports betting license — their company type, whether they are publicly traded, management structure, investors, and information about parent companies.
