Prediction market offers. Read the conditions first.
Compare Kalshi, Polymarket US, OG and ProphetX offer headlines. Check qualifying actions, reward limits and eligibility before funding.
Kalshi (opens in a new tab), Polymarket US (opens in a new tab), OG.com and ProphetX (opens in a new tab) have partner offers tied to qualifying actions. The amounts alone do not tell you whether a reward is credited, restricted, expiring or withdrawable. Current location eligibility and full campaign terms control. Do not deposit solely because a headline seems large.
| Platform | Offer headline | Qualifying action in headline | Important distinction |
|---|---|---|---|
| Kalshi | Trade $25 and Get $25! | Trade | New users; reward mechanics need full terms. |
| Polymarket US | Deposit $10 get a $25 Trading Bonus! | Deposit | Trading bonus; check how it can be used before relying on its value. |
| OG.com | Trade $25 Get $50 in Rewards! (New users only) | Trade | Rewards; link does not automatically populate promo code. |
| ProphetX | Trade $50, Earn $75! | Trade | Reward conditions and availability need confirmation. |
A deposit is not a trade. A trading bonus or reward is not necessarily withdrawable money. Neither a partner state list nor a federal exchange registration resolves New York access questions.
Before any sign-up
Check the offer behind the headline.
01Eligibility
Check jurisdiction, age, new-user status and product; never use a workaround to bypass restrictions.
02Qualification
Find the exact eligible action, minimum amount, timing, excluded markets and whether a placed order must actually execute.
03Reward value
Verify credit type, expiry, use limits, withdrawal conditions and what happens if a trade is cancelled or an account is restricted.
04Risk and exit
Inspect fees, funding holds, withdrawal process and maximum loss. Keep the bonus separate from a contract’s expected outcome.
The four partner offers
New York changes the question.
New York announced lawsuits against Kalshi and Polymarket US in 2026. OG (opens in a new tab) announced a New York launch in June 2026. The CFTC lists ProphetX as a designated exchange, but that listing alone does not confirm an individual New York account or contract. See our New York access guide and dated timeline. These are developing matters, not a live legal eligibility determination.

Frequently asked questions
Which prediction market bonus is best?
No reliable best-value claim follows from the four headlines. They differ in action, reward type and unverified restrictions. Compare complete current terms and the underlying product before assigning value.
Is the $25 Polymarket bonus cash I can withdraw?
The headline says trading bonus. We have not independently verified its withdrawal, expiration or use conditions, so do not count it as $25 cash.
Do I need to enter NYPREDICTS?
The code is NYPREDICTS. The OG referral link does not auto-populate it; other destination flows may vary. Check the current offer and code field before qualifying activity.
Can someone in New York claim every offer?
No such guarantee is made. Product, location, age, legal conditions and campaign eligibility need current confirmation on each platform.
