Fee Disclosure
Effective: September 2, 2026
The ForecastEx transaction fee, how Lumina Markets is compensated, the incentive coupon, withdrawal fees, and every other charge that can apply.
1. Overview
Prediction Market Contracts are listed and traded on ForecastEx, LLC (“ForecastEx”), the CFTC-regulated designated contract market. ForecastEx charges a transaction fee for facilitating each transaction. Lumina Markets Inc. (“Lumina”), as the introducing broker, is compensated through a rebate that represents a share of that ForecastEx transaction fee — not through any charge added on top of what the customer pays. Separately from the transaction fee, cash collateral backing your open contracts earns interest, a portion of which is credited to you as an incentive coupon. ForecastEx deducts a fee from that interest before the coupon is paid. See Section 4.
2. ForecastEx Transaction Fee
ForecastEx charges a transaction fee for facilitating each transaction on its market. The key features of this fee are:
- Rate: $0.01 per contract, charged per side. Both the “Yes” side and the “No” side of each executed transaction are charged this fee.
- Timing: The fee is charged at the time of execution. It is independent of how the contract ultimately resolves, and it is not affected by netting or settlement.
3. How Lumina Is Compensated
Lumina receives a rebate equal to one-quarter (25% or $0.0025) of the ForecastEx transaction fee. This rebate is Lumina’s share of the exchange’s transaction fee. It is not a separate or additional charge added on top of what the customer pays.
The total fee a customer pays per contract, per side, does not increase because of this rebate. ForecastEx charges its transaction fee and remits a portion of it to Lumina as Lumina’s compensation for introducing the customer’s business.
4. Incentive Coupon on Contract Collateral
When you hold a Prediction Contract, the amount you paid is held as cash collateral at the ForecastEx clearinghouse. That collateral earns interest, and a portion of it is credited to your account periodically as an incentive coupon.
Effective August 17, 2026, ForecastEx withholds an administrative clearing fee equal to 50 basis points (0.50%) of the interest earned on cash collateral before the coupon is paid. If the interest earned is less than 50 basis points, ForecastEx retains all of it. This fee cannot reduce the coupon below $0.
Lumina does not pay the coupon, does not deduct anything from it, and receives no part of it.
The coupon is variable — the amount you receive depends on prevailing interest rates and the value of your contracts, and it may be zero.
5. Fee Summary
| Fee type | Amount / description |
|---|---|
| ForecastEx transaction fee | $0.01 per contract, charged per side — both the “Yes” side and the “No” side of each executed transaction are charged. Charged at the time of execution. Set and charged by ForecastEx, not by Lumina. |
| Commission, markup, or surcharge charged by Lumina | None. Lumina does not add any separate or direct charge on top of the ForecastEx fee. |
| Lumina compensation | A rebate equal to one-quarter (25% or $0.0025) of the ForecastEx transaction fee. This is Lumina’s share of the exchange’s fee, not an additional charge to the customer. Because it is a share of the per-transaction fee, Lumina earns more as trading volume increases. |
| Contract pricing | Contracts are priced between $0.02 and $0.99 per contract, reflecting the market’s assessed probability that the underlying event will occur. |
| Bid/ask spread | The spread between the best available buy and sell prices on the ForecastEx order book may affect a customer’s execution price. This spread is determined by market participants. |
| Withdrawal fees | The first two withdrawals per calendar month are free. Subsequent withdrawals in the same month are subject to the fees in the table below. These fees are charged by IBKR, not by Lumina. Lumina does not receive any portion of these fees. Additional fees from correspondent or beneficiary banks may also apply and are outside IBKR’s or Lumina’s control. |
| Incentive coupon on contract collateral | Cash collateral backing your open contracts earns interest, a portion of which is credited to you as an incentive coupon. ForecastEx withholds an administrative clearing fee of 50 basis points of that interest before the coupon is paid (effective August 17, 2026). Lumina deducts nothing from the coupon and receives no part of it. See Section 4. |
| Other fees | None. Lumina does not charge account maintenance fees, inactivity fees, deposit fees, or any other fees. The ForecastEx administrative clearing fee described above is charged by ForecastEx, not by Lumina. |
