Underdog offers prediction-market trading through Underdog Predict and its Prediction Picks experience. Its current exchange explainer names UDX, Kalshi and Nadex. A position settles under the rules of the exchange that offered its market. The app name alone does not tell you which rulebook applies.
Reviewed November 9, 2026. This guide explains how to research the product and read a position. Examples are fictional; prices, fees, eligibility and available features must be checked in the current product.
Which exchange powers an Underdog Prediction Pick?
Underdog’s explainer says it presents one market per game and handles the underlying exchange selection. Positions can be held across more than one exchange at a time. That makes the exchange attached to your particular position more useful than a general claim that Underdog “uses Kalshi.”
The official Predict disclosures distinguish UDM, LLC, doing business as Underdog Predict, a futures commission merchant; Aristotle Exchange DCM, Inc. and Aristotle Exchange DCO, Inc., described as Underdog Exchange or UDX; and a Crypto.com Derivatives North America arrangement involving Underdog as a technology provider. These are different roles. Check the agreement applicable to your account and the venue associated with your contract.
| Question | Where to look | Why it matters |
|---|---|---|
| Who holds my account? | Accepted account agreement and legal entity | Identifies the account arrangement |
| Which exchange offered this market? | Position details and market rules | Identifies the applicable rulebook |
| What outcome wins? | Individual contract specifications | Defines the actual settlement condition |
| Can I exit before settlement? | Current cash-out offer and order status | Separates an available exit from an assumed one |
Prediction Picks and Fantasy balances need separate checks
The current Prediction Picks rules distinguish UDM futures accounts from Underdog Fantasy accounts. For the UDM arrangement, the page describes separate balances, transfers supporting prediction trades and different protections for funds held in the futures account versus the Fantasy account.
Identify whether the entry you are viewing is a Prediction Pick, Fantasy entry or Combo. A familiar interface does not make their account terms, cash-out behavior or funds identical. Read the current Predict legal center and the terms accepted for your account before relying on a general product summary.
How Underdog prediction cash out works
The current Prediction Cash Out guide describes an early sale at the current market value. The result can be above or below your entry cost, and exchange fees may apply. A cash-out figure is not automatically a profit figure.
For a fictional example, 40 contracts bought at $0.60 cost $24 before fees. Selling all 40 at $0.65 produces $26 before exit fees. The $2 difference is the gross trading result, not the $26 sale proceeds. Subtract the actual entry and exit fees to calculate the net result.
Cash out depends on availability and liquidity. The rules require an eligible physical location, and the feature may not always be offered. Avoid building a position calculation around an exit you have not actually received.
An auto cash out can fill only part of a position
Underdog’s guide describes auto cash out as a limit order at a target price or better. It requires enough buyers and is not guaranteed to fill. Editing the target replaces the order for unsold contracts and can affect its place in line. Canceling the instruction leaves the remaining position open.
Suppose a fictional 40-contract position has an auto cash-out target of $0.65. If 15 contracts sell, the gross proceeds are 15 × $0.65 = $9.75, and 25 contracts remain. If those remaining contracts later settle at $0, total proceeds stay $9.75 before fees; if they settle at $1 each, total proceeds are $34.75 before fees. A partial sale does not lock the whole position at the target price.
The inspected guide limits auto cash out to eligible single Prediction Picks, excluding parlays, Combo entries and Fantasy picks. It also says manual cash out is unavailable while an auto cash out is active. Check the current feature instructions for your entry rather than treating all entry types alike.
Compare the full cost, not one fee example
Record the actual entry price, quantity and fee estimate, then reconcile them with confirmed fills. For an early exit, record sale proceeds and any additional fee separately. For settlement, use the contract’s actual payout and result. A fee shown in an educational example does not establish one universal rate across exchanges, products and dates.
For Combo entries, the cash-out guide describes proceeds from the Prediction portion rolling into the Fantasy entry fee when cashed out before the Fantasy picks go live. Check the linked Combo rules and the entry breakdown before treating that amount as withdrawable cash.
