The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that, among other things, provide a marketplace platform accessed within various application environments, such as a gaming environment associated with a video game. The market platform automatically determines product advertisements that appropriate for presentation within the gaming environment based on an application of trained machine learning and artificial intelligence models to selected elements of input data, and facilitates a purchase of advertised products without a user's exit from the gaming environment by maintaining centralized elements of profile data characterizing the user.
