Zero-Sum Games

Context

In financial markets, particularly within cryptocurrency derivatives, options trading, and related instruments, the concept of zero-sum games describes scenarios where one participant’s gain directly corresponds to another participant’s loss, with the total net change in wealth across all participants equaling zero. This contrasts with positive-sum games, where all participants can benefit, or negative-sum games, where all participants experience a net loss. The prevalence of zero-sum dynamics is often debated, as transaction costs, taxes, and informational asymmetries can introduce elements that shift the overall outcome. Understanding this framework is crucial for assessing risk and formulating trading strategies, especially in highly leveraged derivative markets.
