arXiv:2602.04397v2 Announce Type: replace-cross Abstract: We study a setting in which two players play a (possibly approximate) Nash equilibrium of a bimatrix game, while a learner observes only their actions and has no knowledge of the equilibrium or the underlying game. A natural question is whether the learner can rationalize the observed behavior by inferring the players' payoff functions. Rather than producing a single payoff estimate, inverse game theory aims to identify the entire set of payoffs consistent with observed behavior, enabling downstream use in, e.g., counterfactual analysis
The paper, published in 2026, reflects ongoing research into fundamental AI capabilities, specifically the ability of AI to infer complex strategic motivations from observed actions, aligning with the accelerating development of autonomous AI systems.
This research provides a foundational understanding for AI agents to interpret and predict behavior in multi-agent environments, critical for developing more sophisticated and adaptive AI systems in competitive or cooperative settings.
The ability to accurately estimate payoff sets in games allows for more robust inverse game theory applications, moving beyond single-point estimates to a more comprehensive understanding of underlying incentives and constraints.

AI agents can better infer hidden motivations and strategies of other agents.
This leads to more effective and adaptive AI behavior in complex, dynamic environments like negotiations or competitive markets.
Advanced capabilities in inverse game theory could enable AIs to design or manipulate incentive structures within human or AI systems by understanding the 'why' behind observed actions.
