Underdog Predict review (2026)

Overview

Underdog, the fast-growing fantasy operator, moved into event contracts as Underdog Predict after acquiring Aristotle's CFTC-regulated exchange and clearinghouse licenses in early 2026. Its signature twist is letting you combine multiple predictions into a single entry, parlay-style.

For sports fans who like building multi-leg entries it's a distinctive option, with a simple built-in margin rather than per-contract fees.

Markets and coverage

Underdog Predict focuses on sports and lets users combine several predictions into one entry. Coverage is sports-led; you won't find broad macro or political markets here.

Fees and funding

Underdog funds in US dollars — no crypto required. Underdog builds its margin into its payout structure rather than charging a separate per-contract fee. Our deposit guide and fees guide cover the detail.
