Prediction market promos can have very different qualification and credit-use rules. A deposit award, referral credit and staged trading incentive are not interchangeable. This comparison, checked October 6, 2026, covers four documented programs and the conditions to compare before funding an account.
Alphascope does not issue these awards or supply exclusive codes. We reviewed public terms; we have not opened accounts to test bonus claims. The campaign shown to your account and its current complete terms determine eligibility. This is a dated comparison, not a promise that every reader can claim every offer.
Prediction market promos compared
These rows summarize different programs. Read the linked official terms and the detailed guide for your venue. A higher nominal award does not establish a better trade, lower risk or more withdrawable money.
| Program | Published offer or requirement | Condition to inspect |
|---|---|---|
| Kalshi referral | Account-specific amount and trading requirement in Rewards | Qualification, claim step and credit expiry |
| Polymarket US deposit campaign | $25 credit for a qualifying deposit of at least $10 | The onboarding campaign presented before deposit |
| Novig new-member deposit program | $50 as five $10 trade credits after a qualifying $10 deposit | Price eligibility, one credit per trade and unused remainder |
| ProphetX new-participant program | Three $25 installments after qualifying position-opening trades using $50 of collateral | Later installments depend on use of earlier credits |
Kalshi: read the account’s Rewards terms
The official referral FAQ makes the reward and trading requirement account-specific. Qualification involves the referral, identity verification and the displayed requirement. It describes US-only incentives, a lifetime cap shown in Rewards and a seven-day credit use window unless otherwise specified. The original credit usually is not withdrawable; profits from using it can be.
Use our Kalshi promo guide for signup entry and claim questions, or the referral-code guide for finding and tracking your personal referral. Neither guide supplies a universally working bonus amount.
Polymarket US: check the specific campaign
The current incentive overview lists a $25 deposit credit after a qualifying deposit of at least $10. The applicable onboarding code or link must present the campaign before the deposit. The overview separately lists friend-referral and deposit-and-trading programs. Do not treat their awards as one automatically combined offer.
These terms concern Polymarket US. They do not establish an international-site offer. The overview says credits cannot be withdrawn as cash and existing collateral is used before credit. Our Polymarket free-$50 guide explains the older search phrase and the current deposit campaign.
Novig: five credits have their own use restrictions
The new-member terms define a new member as someone who has not previously traded on the exchange. Eligibility includes approval, verification, a linked payment method and the qualifying deposit during the campaign. Age and jurisdiction restrictions apply.
The five $10 credits expire 30 calendar days after issuance. Eligible contract prices range from $0.01 to $0.60 inclusive; only one credit can be applied per trade, and unused remainder is forfeited. Automated use is prohibited. The program excludes combining these credits with other Novig incentive programs. Settled proceeds follow ordinary withdrawal procedures without a trading-volume requirement under this deposit program. See our Novig promo guide for the separate referral-credit rules.
ProphetX: the installment schedule is conditional
The official filings directory links the August 27 amendment effective September 11. First-time approved participants must use $50 of aggregate collateral on position-opening trades within 30 days of account approval. Fills above $0.80 do not count.
Qualification is Day 0. The $25 installments are scheduled for Days 1, 7 and 14. Day 7 requires full use of the first installment; Day 14 requires full use of both earlier installments. Missing a utilization condition forfeits that and later installments. Each issued installment has a 45-day use window; withdrawal requires position settlement. The program’s stated end is the earlier of December 31, 2026 or 50,000 qualifiers, subject to its terms. Our ProphetX bonus guide explains the distinctions from its referral program.
Compare three questions, not just the headline
- Can you qualify? Record the account, product, location requirements, qualifying action and deadline.
- Can you use the award as intended? Check eligible contracts, prices, credit sizes, expiry and installment conditions.
- What becomes withdrawable? Separate the original award, settled proceeds and payment-provider delivery.
Consider a fictional $10 credit usable once, with unused remainder forfeited. Applying it to an $8 eligible order would use $8 of its nominal buying power and lose $2 of unused value. That says nothing about whether the order will win. This arithmetic illustrates why the headline and usable amount can differ; it is not an expected-return estimate or a recommendation to place an order.
Similarly, “trade $50” can describe collateral, notional volume or a different defined amount. Use the campaign’s own definition. A completed signup, submitted deposit and executed trade are separate events, and none should be substituted for another without checking the terms.
If an expected award is missing
Compare the offer saved at signup with verification, qualifying activity, payment status and any claim step. Document the actual error and time. Ask official support which requirement remains unmet before adding funds or repeating an order. Keep account credentials and identity documents in the official account process.
For trade research, read the contract’s resolution rules and executable quote independently of the promotion. The profit calculator models hypothetical payout and loss; it does not determine promotional eligibility. An award is not evidence about an event’s probability.
