By PredictQ Team // Updated: July 2026
The straight answer first: as of July 2026, Underdog Predict has no dedicated welcome bonus or promo code for prediction market signups. None. That puts it behind Kalshi (Trade $10, Get $10), Polymarket (Deposit $20, Get $50), OG.com (up to $100 in volume-based milestone bonuses), DraftKings Predictions (Spend $5, Get $25 in Predictions Dollars), and FanDuel Predicts ($25 for a deposit and a real-money trade).
What Underdog does have is a real bonus on the DFS side: Play $5, Get $50 in bonus entries. It’s worth claiming if you’re going to use both halves of the app. It is worthless if you only care about Predict, because it cannot be spent on event contracts. This guide covers what’s actually available, where the DFS bonus does and doesn’t apply, and where to go if bonus size is driving your decision.
What’s Available
Underdog’s standing new-user offer lives entirely on the fantasy product. Play $5 on a DFS entry and you get $50 in bonus entries through partner promo codes. Those bonus entries work on DFS formats (Drafts, Pick’em, Best Ball) and carry a standard 1x playthrough before associated winnings become withdrawable.

Where That Bonus Stops
The $50 in DFS bonus entries does not touch prediction markets. Underdog Predict is a separate product underneath the unified app, with its own payment rails, its own tax treatment, and its own account mechanics. Specifically:
- Bonus entries from the welcome offer can only be used on DFS picks (Drafts, Pick’em, Best Ball).
- Bonus entries cannot purchase event contracts on Underdog Predict.
- Profit Boost tokens, No Sweat tokens, Gimme Pick tokens, Multiplier Boosts, and the Playback Program are all DFS-only tools.
- Refer-a-Friend bonuses pay out in DFS entries.
The wall exists for regulatory reasons. Fantasy sports are state-regulated; event contracts are federally regulated by the CFTC. Money and promotional credit don’t cross that line.
Why There’s No Predict Bonus
CFTC oversight makes platforms cautious about promotional structures that look like inducements to take on financial risk. That’s why prediction market bonuses across the industry run modest: Kalshi’s $10 match, FanDuel’s $25, OG.com’s milestone structure capped at $100. Nobody is handing out sportsbook-style $1,000 first-bet offers.
Underdog has gone further than cautious and simply hasn’t launched a Predict offer at all. That could change once the Aristotle Exchange migration completes and Underdog controls its own listings and promotional stack. For now, plan on zero.
The Combo Entry Bridge
One genuine connection exists between the two products: combo entries, which let you pair DFS picks with Predict event contracts in a single multi-leg entry. No other prediction market offers anything like it. Combos run on the DFS payment structure (entry fees on the DFS side) while pulling in Predict contracts as legs. The mechanics keep evolving, and the specific offerings depend on what markets are live at any given time.
How to Sign Up and Capture the DFS Bonus
Even though it doesn’t apply to Predict, the $50 is free value if you’ll use both products. The process:
- Click HERE to start. The DFS bonus tracking applies through this link.
- Download the Underdog app from the iOS App Store or Google Play, or sign up on the website.
- Register with your legal name, date of birth, email, phone number, and the last four digits of your SSN.
- Complete KYC with a government-issued photo ID and a selfie.
- Deposit at least $5. Debit card, PayPal, bank transfer, and Trustly all work.
- Place a first DFS entry of at least $5. The $50 in bonus entries credits to your account.
- Use the bonus entries on DFS picks within the validity window.
- If you’re in an eligible Predict state, activate the Predict section. The bonus won’t follow you there, but your verified account works for both products.
Other Underdog Promotions
Underdog runs periodic DFS promotions beyond the welcome offer: Profit Boosts (typically capped around $50 in extra winnings), sport-specific boosts, Refer-a-Friend entries, No Sweat tokens, and Multiplier Boosts. Every one of them is DFS-only. If a Predict-specific promotion ever launches, we’ll update this page the day it does.
Bottom Line
No Underdog Predict promo code exists as of July 2026. The Play $5, Get $50 DFS offer is real, but it can’t buy a single event contract. If you’re going to use both sides of the app, claim the DFS bonus and activate Predict separately. If you’re purely bonus-shopping for prediction markets, OG.com’s milestone structure (up to $100) and Polymarket’s Deposit $20, Get $50 pay more for less effort.
