AthX is a sports trading platform where you buy and sell shares of MLB players and teams. For a full definition, category, and FAQs, see What is AthX?
This page covers the mechanics: trading rules, fees, pricing, dividends, bonuses, IPO, force-sells, and scoring.
Prices are updated based on two main inputs:
A holding is eligible when it meets the platform’s “on pace” requirement. Eligibility is determined automatically and shown in-app.
Standard users pay a 1% buy fee. AthX Pro users pay 0%.
Manual sell fees vary for standard users (typically ~3%). AthX Pro users have a 2% baseline manual sell fee. All fees are shown before you confirm.
IPO price = projected fantasy points for the rest of the season
Scoring varies by sport. Below is the current baseball scoring used for the 2026 launch.
