What is a Zero-Sum Game? 🎲
In financial parlance, a Zero-Sum Game is a scenario where one person’s gain is directly balanced by another’s loss, resulting in a net output of zero. Imagine a poker game: when you win, the other players lose. Simple as that—it’s the harsh but necessary mathematics of competition!
A zero-sum game is a situation in which the total gains and losses among players sum to zero. In simpler terms, if “Player A” gains a dollar, “Player B” loses a dollar, leaving the overall wealth unchanged.

A: Not all! While options and futures are zero-sum, stock markets can be non-zero-sum as both the buyer and seller can profit over time.
Q: Can players change the payouts in zero-sum situations?
A: Generally, no! Zero-sum games have fixed payouts; it’s like agreeing on a bet—you can’t change it after you’ve rolled the dice.
