Authorized Participant (AP)
An authorized participant is a financial institution — typically a large broker-dealer or market maker — contractually authorized by an ETF sponsor to create and redeem ETF shares directly with the fund, maintaining the arbitrage mechanism that keeps ETF market prices aligned with net asset value.
Definition
As of Q1 2026, the global ETF industry surpasses $14 trillion in assets under management, and every dollar of that AUM depends on a small group of financial institutions known as authorized participants (APs) to function correctly. An authorized participant is a registered broker-dealer or financial institution that has entered into a contractual agreement — called an AP Agreement — with an ETF sponsor to create and redeem ETF shares directly with the fund. APs serve as the critical arbitrage mechanism that keeps ETF market prices aligned with the fund’s net asset value (NAV). Without APs, ETFs would trade like closed-end funds, frequently drifting to persistent premiums or discounts.
The AP ecosystem is remarkably concentrated. Roughly eight firms — Jane Street, Virtu Financial, Citadel Securities, Goldman Sachs, JP Morgan, ABN AMRO, Cantor Fitzgerald, and Flow Traders — handle the vast majority of ETF creation and redemption activity across the $14 trillion market. This concentration has raised questions about systemic risk, particularly during periods of extreme market stress such as the March 2020 COVID-driven selloff when AP activity in certain fixed-income ETFs briefly contracted.
The Creation-Redemption Mechanism
When an ETF trades at a premium to NAV, APs create new shares by delivering a basket of underlying securities to the fund and receiving ETF shares in return. These newly created shares are sold on the secondary market, increasing supply and pushing the ETF’s trading price back toward NAV. Conversely, when the ETF trades at a discount, APs redeem shares by delivering ETF shares back to the fund and receiving the underlying basket of securities. This reduces the outstanding share count and supports the ETF price.
This creation and redemption mechanism operates under SEC Rule 6c-11, which establishes the regulatory framework for ETF basket policies and transparency requirements. Rule 6c-11, adopted in September 2019, replaced the prior exemptive-relief process and standardized key operational requirements including daily portfolio transparency, basket publication, and website disclosure obligations.
The process works in creation units — typically blocks of 25,000 to 100,000 shares valued between $5 million and $15 million. The AP does not charge the fund a fee for its services; instead, the AP profits from the arbitrage spread between the ETF’s market price and the value of the underlying basket, plus any transaction fees charged to other market participants.
Settlement Timelines and Counterparty Risk
Under the current regime, ETF creation and redemption transactions settle on a T+1 basis in the United States (since May 2024) and T+2 in most European markets. During this settlement period, both the AP and the fund bear counterparty exposure. The AP has delivered (or committed to deliver) the creation basket but has not yet received the ETF shares, or vice versa. DTCC manages this risk through its National Securities Clearing Corporation (NSCC) subsidiary, which acts as the central counterparty and guarantees settlement.
In Europe, the settlement infrastructure involves Euroclear and national central securities depositories, with the ECB exploring wholesale CBDC settlement as a future alternative for the cash leg of delivery-versus-payment transactions.
Tokenization Impact on the AP Function
In tokenized ETF structures, the AP function could be fundamentally transformed through smart contracts that enforce basket composition rules and enable atomic settlement. The comparison of traditional and tokenized AP models examines how blockchain technology reshapes AP operations across several dimensions.
Settlement Compression
The most immediate impact is settlement compression from T+1 (or T+2) to near-instantaneous atomic settlement. When creation and redemption occur through smart contracts on a blockchain, the exchange of the creation basket for ETF share tokens happens in a single atomic transaction — either both legs complete or neither does. This eliminates the settlement window entirely, removing counterparty risk and freeing up capital that would otherwise be posted as margin or collateral.
BlackRock’s BUIDL fund, launched in March 2024 and now at $2.01 billion AUM across 8 chains (Ethereum, Avalanche, Polygon, Arbitrum, Optimism, Aptos, Solana, and Base), demonstrates this principle at institutional scale — BUIDL has been listed as collateral on Binance and trades on Uniswap DEX. Franklin Templeton’s BENJI token ($1.01 billion AUM across 9 chains, 63% on Stellar, with patent-pending intraday yield distribution) has established blockchain-native settlement as operationally viable for registered fund products. WisdomTree’s WTGXX ($742.8 million AUM) received SEC exemptive relief on February 24, 2026, for 24/7 trading — the first tokenized mutual fund with this authorization.
Democratization of AP Access
Today’s AP oligopoly exists partly because of the massive capital and operational infrastructure required to participate in the creation-redemption process. An AP must maintain: broker-dealer registration with the SEC and FINRA; relationships with custodian banks and prime brokers; trading desks capable of executing large basket trades; back-office systems for managing in-kind transfers; and significant balance sheet capacity for inventory management.
Tokenized ETF structures could lower these barriers. If creation-redemption is governed by permissioned smart contracts rather than bilateral agreements and manual processes, the operational overhead drops significantly. Smaller broker-dealers or even institutional investors could potentially qualify as APs, increasing competition and tightening bid-ask spreads for end investors.
Programmable Basket Composition
Smart contract-based creation and redemption enables programmable basket management. The fund’s smart contract can automatically verify that a proposed creation basket matches the published composition, reject non-conforming baskets, and adjust for corporate actions — all without human intervention. This reduces the operational errors that occasionally occur in traditional basket processing and ensures real-time compliance with Rule 6c-11 basket requirements.
Regulatory Considerations for Tokenized AP Models
The SEC Division of Investment Management has not issued specific guidance on how AP agreements should be structured for tokenized ETF products. Current practice, as demonstrated by Franklin Templeton and other early movers, is to maintain traditional AP agreements while adding blockchain-specific operational procedures.
In the European Union, ESMA is developing technical standards under the DLT Pilot Regime that address how authorized participant functions should operate on distributed ledger infrastructure. The MiCA regulation, effective July 2026, introduces additional requirements for crypto-asset service providers that may interact with tokenized fund creation-redemption processes.
The Hong Kong SFC has taken a more prescriptive approach, requiring that tokenized fund structures maintain equivalent AP arrangements to their traditional counterparts, with additional technology governance requirements covering smart contract security and oracle network reliability.
For institutional investors evaluating tokenized ETF products, the institutional investor guide provides a comprehensive framework for assessing how AP arrangements in tokenized structures compare to traditional standards. See also the SEC’s custody rules for digital asset funds for requirements affecting the custodial leg of AP operations.
