What Is an Introducing Broker? Complete 2026 Guide

An introducing broker (IB) is a firm or individual that introduces clients to a larger broker and is paid for the trading those clients generate, without ever holding the clients' funds or clearing their trades. The IB owns the relationship and the marketing; the broker behind it holds the money, executes orders, and carries the regulatory and counterparty risk. This split — relationship on one side, custody and clearing on the other — is the defining feature of the model, and it is identical in shape whether the underlying product is forex, futures, equities, or CFDs. This guide defines the introducing broker role across every asset class, explains exactly how IBs get paid, maps the broker-IB-clearing chain, and shows operators how an IB program is actually run.

Introducing broker definition: the precise meaning

The introducing broker definition is consistent across regulators and asset classes: an IB solicits or accepts client business and introduces it to another broker that carries the account, but the IB does not accept money, securities, or property to margin, guarantee, or secure the resulting trades. That single restriction — no custody of client funds — is what separates an introducing broker from a full-service or clearing broker. The IB is a referral, onboarding, and service layer sitting on top of someone else's regulated balance sheet and execution infrastructure.

The introducing broker meaning is sometimes blurred with 'affiliate', but they are not the same. An affiliate typically drives anonymous traffic and is paid on a sign-up or first-deposit basis with little ongoing client relationship. An IB usually has a named, advisory, or service relationship with the introduced clients, often educates or supports them, and earns on their ongoing trading activity for the life of the account. In forex specifically the distinction is sharper still; for the forex-narrow treatment of that line, read our dedicated explainer on [what IB means in forex](what-is-ib-in-forex-guide), which goes deeper on the forex-only mechanics. This pillar stays cross-asset.

Introducing brokers across asset classes: forex, futures, equities, CFDs

The IB concept originated in US futures, where the term is a formal regulatory category, and then spread by analogy into forex, CFDs, and equities. The economics rhyme across all four, but the regulatory framing and the unit of commission differ. Understanding those differences is essential before you design or join an IB program.

Notice the pattern: in every column the IB introduces clients to a firm that holds the money and clears or carries the trades, and the IB is compensated as a share of the economic activity those clients produce. The futures version is the most tightly regulated as a named category; the forex and CFD versions are the most varied because the broker behind the IB may be regulated by CySEC, the FCA, ASIC, the FSC Mauritius, the FSA Seychelles, or another authority depending on the target market. The US equities version is a registered introducing broker-dealer, governed by the SEC and FINRA, and is a distinct registration from the futures IB.

How does an introducing broker get paid?

An introducing broker is paid by the broker it introduces clients to, out of the revenue those clients generate. There is no fee to the client beyond the spreads and commissions they already pay — the IB's compensation is carved from the broker's economics. There are five compensation structures, and most programs combine them.

• Per-lot / per-contract commission: a fixed amount per traded lot (forex) or round-turn contract (futures). Predictable and volume-linked, this is the workhorse model for active-trading IBs.
• Spread rebate: the IB earns a slice of the spread (in pips, then converted to currency) on every trade the introduced client makes. Common in forex and CFDs.
• Revenue share (RevShare): the IB earns a percentage of the net revenue the broker books from the client over the life of the account — strongest when client retention is long.
• CPA (cost per acquisition): a one-time payment when an introduced client funds and trades to a threshold. Useful for high-volume acquisition IBs but ignores lifetime value.
• Hybrid: a smaller CPA plus ongoing RevShare or rebate, balancing the IB's cash-flow needs against the broker's lifetime economics.

Sophisticated IB programs run multiple tiers: a master IB recruits sub-IBs and earns an override on the sub-IBs' production. That multi-tier override math — and the reconciliation behind it — is where commission engineering gets hard, because a single trade can trigger a per-lot rebate to the originating IB and a percentage override to one or more IBs above them. For a full evaluation of how to structure and compare these programs, see our guide to the [best forex IB program structures](best-forex-ib-program-guide). For the underlying platform that automates the calculation, brokers rely on a [commission-management engine](/features/commission-management) rather than spreadsheets.

The introducing-broker model only scales when the broker can prove — trade by trade — which IB introduced which client, and pay the right override up every tier without manual reconciliation. The concept is simple; the accounting underneath it is not.

The broker-IB-clearing chain: who does what

To understand an introducing broker you have to see the chain it sits in. A retail client's order passes through up to three distinct roles before it is settled, and the IB is the first link — the one closest to the client and furthest from the money. The other links execute and clear.

1. Introducing broker (IB): owns the client relationship, markets, onboards, and services. Holds no client funds. Paid a commission/rebate/RevShare on the client's activity.
2. Executing broker: routes and executes the order in the market or against its own book. May be the same entity as the carrying firm or a separate one.
3. Clearing / carrying broker: holds client funds and positions, manages margin, settles trades, issues statements, and carries counterparty and regulatory custody risk.

In a small forex setup, execution and clearing/carrying often sit inside one broker, so the chain is effectively two links: IB and broker. In US futures and equities the roles are more clearly separated, with the carrying/clearing firm a distinct regulated entity. The critical operator insight is that the IB never touches client money — which is precisely why an IB is faster and cheaper to set up than a full broker, but also why the IB depends entirely on the broker behind it for execution quality, payout reliability, and regulatory standing. We unpack each role and where they pass funds and risk in [introducing broker vs clearing broker explained](introducing-broker-vs-clearing-broker-explained-2026).

Introducing broker vs full broker vs affiliate

Three roles are routinely confused. A full broker holds client funds, executes or clears trades, and carries the heaviest regulatory load and capital requirements. An introducing broker introduces and services clients but holds no funds — a lighter footprint, lower capital, faster to launch, and dependent on the broker behind it. An affiliate drives traffic and is typically paid CPA or RevShare for sign-ups with little ongoing client relationship and usually no advisory contact.

From the broker's operating perspective, IBs and affiliates are usually managed by the same partner infrastructure even though they are legally and behaviourally different — both need attribution, both need commission calculation, both need a place to log in and see their stats. That shared infrastructure is the [affiliate and IB partner portal](/features/affiliate-portal), and it is where the practical line between 'affiliate' and 'IB' becomes a configuration choice rather than a separate system.

Is an introducing broker regulated?

Whether an introducing broker is regulated depends entirely on jurisdiction and asset class. In US futures, an IB is a formal NFA-registered category supervised by the CFTC, with registration, qualification exams, and minimum net-capital obligations unless the IB is guaranteed by an FCM. In US equities, an introducing broker-dealer is registered with the SEC and is a FINRA member. In the EU, an IB introducing clients to an investment firm often operates as a tied agent under that firm's authorisation; in the UK, the analogous structure is an appointed representative operating under a principal firm authorised by the FCA. In offshore forex/CFD markets, IBs frequently operate under a contractual agreement with the broker without a separate licence, with the broker holding the regulated permission.

Because the rules diverge so sharply by market, the single most common operator mistake is assuming the IB framework that applies to one asset class or region applies everywhere. The detailed US picture — guaranteed vs independent IBs, NFA registration, Series 3/30, and net-capital thresholds — is covered in our [introducing broker dealer CFTC/NFA registration guide](introducing-broker-dealer-cftc-nfa-registration-requirements-2026).

How operators actually run an introducing broker program

For a broker or prop firm, 'introducing broker' is not a definition — it is a revenue channel that has to be built and operated. The operational stack has four parts: recruitment and onboarding of IBs, tracking of which clients each IB introduced, calculation of commissions and multi-tier overrides on every trade, and reliable, auditable payout. Each part fails differently when under-built.

• Tracking & attribution: server-to-server (S2S) postbacks and tagged links tie each introduced client and every trade to the originating IB and the tiers above — the foundation everything else depends on.
• Commission engine: rules for per-lot, rebate, RevShare, CPA, hybrid and tiered overrides, applied automatically per trade rather than reconstructed in a spreadsheet each month.
• Partner portal: a login where IBs see real-time stats, sub-IB production, and pending and paid commissions — transparency is what keeps productive IBs loyal.
• Payouts & finance: scheduled, reconciled, multi-currency (and increasingly crypto) payouts with an audit trail your finance and compliance teams can defend.

This is the core of what Track360 does: a single platform that tracks introductions via S2S, calculates multi-tier IB commissions in any model on a per-trade basis, gives each IB a transparent portal, and automates reconciled payouts. It is built specifically for forex/CFD brokers and prop firms running IB and affiliate channels side by side. To see how the pieces fit together for a broker, explore the [Track360 product overview](/product) or the [commission-management engine](/features/commission-management) that handles the multi-tier override math IB programs live or die on.

Frequently asked questions

The introducing broker is one of the most durable structures in the trading industry precisely because it cleanly separates the client relationship from the custody of funds. That separation works across forex, futures, equities and CFDs, lowers the barrier for partners to enter the market, and gives brokers a scalable acquisition channel. The concept is simple; the accounting underneath — attribution, multi-tier overrides, and reconciled payouts — is what determines whether an IB program scales or stalls. Build that layer correctly and the model does the rest.
