How Arbitrage Keeps Tokenized Stock Prices in Line — and Why It Can't Work Perfectly 24/7

TL;DR: Tokenized stock prices are usually kept near real-stock prices by professional market makers and arbitrage participants using issuer-approved or venue-supported channels, inventory, and hedging capacity. The mechanism can narrow gaps, but it cannot guarantee perfect 24/7 alignment. Alignment is not automatic — a tokenized stock tracks the underlying because professional participants trade differences through issuer-approved or venue-supported channels, inventory, hedging, and reference-pricing mechanisms, not because the token “knows” the stock price. Most users see the result, not the loop, and primary access is gated by onboarding, identity verification, jurisdiction, and minimum size rather than by market-maker status. The loop also has a ceiling: market hours, issuer-channel access, inventory and hedging limits, reference-price behavior, and liquidity depth all constrain how tightly the gap can be closed — especially outside regular market hours. This is not investment advice and not a critique of any issuer, wallet, or exchange.

What this is about — and what it is not

This reference is not about why 24/7 token trading does not equal 24/7 price discovery — that question is covered separately, in Why 24/7 Tokenized Stocks Do Not Mean 24/7 Price Discovery. This piece focuses on the alignment mechanism itself: who keeps tokenized stock prices close to the underlying, what channels they use, and why that mechanism has limits.

The distinction matters. The price-discovery reference looks at the problem from the side of someone reading a price: when is the number on screen reliable, and when is it an estimate? This reference looks at it from the other side — the side of the people whose job is to keep that number close to the underlying. Understanding who they are, what they need, and where they hit walls explains both why alignment usually works and why it is never perfect.

Who keeps tokenized stock prices aligned?

A tokenized stock stays close to its underlying because of arbitrage — but arbitrage here is infrastructure, not a retail trade.

Most users see the result of arbitrage; they do not participate in the full arbitrage loop.

When a tokenized stock drifts from the underlying, the participants who close the gap are typically professional market makers, issuer-side partners, and, where a product defines that role formally, authorized participants. They are the ones with the standing access and capital to run the full loop: spot the gap, act on it through issuer channels, and hedge the exposure in between. An ordinary wallet holder who notices a price difference is usually looking at a gap that these participants either cannot fully close right now (see the limits below) or are already in the process of closing.

This is why a visible gap is not the same thing as a free trade. The gap you can see is the part of the mechanism that has not yet been worked away — and the reasons it has not been worked away are usually structural, not an opportunity sitting in the open.

What the arbitrage loop needs to work

For arbitrage to pull a tokenized stock back toward its underlying, several things have to be available at once:

• An issuer mint/redeem or venue-conversion channel. A participant needs access to an eligible channel that links the on-chain token to the off-chain share exposure, cash settlement, underlying equity conversion, or reference mechanism, depending on the product. This is the core of the loop. Where these channels are documented in detail they look like request-for-quote systems rather than pooled trading: xStocks describes xChange as an atomic RFQ where the client requests a quote, receives a ready-to-execute authorization, and settles both legs in a single transaction, with no partial execution.
• Underlying market liquidity. The participant has to be able to trade the underlying share to complete and hedge the loop. When the underlying market is closed, this side is constrained.
• Inventory. Holding tokens or underlying shares to bridge timing gaps requires capital tied up as inventory.
• Hedging capacity. Between opening and closing the loop, the participant carries exposure, and usually needs to hedge it across venues.
• A reference price. Quoting and risk-managing the position relies on reference prices (oracle feeds, model prices) that the participant trusts.

When all of these are available, the loop runs efficiently and gaps stay narrow. When any one of them is constrained, the loop runs less efficiently — which is the subject of the limits section.

Why ordinary wallet users usually cannot do the full arbitrage loop

The reason “see a gap, close a gap” is not realistic for most holders is that the loop above requires things ordinary self-custody users typically do not have:

• Gated mint/redeem access. Issuer creation and redemption is not open to any wallet: it takes onboarding, identity verification, jurisdiction eligibility, and a minimum ticket. The gate is not a market-maker licence, though, and its height varies sharply by issuer. xStocks documentation states that retail users are legally permitted to redeem directly with the issuer, subject to KYC and a $5,000 minimum transaction size; Ondo documents a $1 minimum for eligible users who complete onboarding and have their wallet allowlisted. Neither serves US persons.
• No direct underlying-market channel. Hedging or completing the loop against the real share requires brokerage/market access most wallet users do not hold in the right form. This, rather than mint access, is usually the binding constraint.
• No inventory or hedging capacity. Running the loop at meaningful size ties up capital and requires cross-venue hedging.
• Cost and latency. Gas, spreads, settlement timing, and execution delay can erode or erase a gap that looked tradeable. Issuer quotes are short-lived by design: Ondo documents a quote guaranteed for roughly 30 seconds, and the xStocks xChange flow documents an execution window of about 60 seconds from quote creation.

The distinction worth holding onto is between access to the primary channel and the capacity to run the loop. Access has been opening up: an onboarded, eligible, non-US retail user can now touch primary issuance at both issuers named above. Running the full arbitrage loop is a different matter, because the hedge leg, the inventory, and the latency budget are what actually make it work.

In practice, ordinary wallet users participate in the secondary market — buying and selling the token itself — rather than in the creation/redemption loop that actually anchors the price. That is a different position in the mechanism, and it is worth knowing which side you are on.

Why issuer structure changes the loop

The alignment loop does not look the same for every product, because the issuer’s structure determines what channels exist and who can use them. The point of the table below is narrow: alignment loops differ by structure. It is not a ranking of which is more efficient.

The descriptions below summarize public issuer and platform disclosures; they are not legal classifications, product recommendations, or rankings.

Issuer	Token form	Underlying custody	Disclosed legal / product form	Relevant disclosed alignment / pricing mechanism
xStocks / Backed	SPL Token-2022 / ERC-20	Alpaca; cash-leg arrangements per issuer documentation	Jersey SPV; bearer debt instrument / tracker certificate	Primary issuance and redemption run 24/5, aligned with underlying market hours, with a $5,000 minimum and KYC. Issuer documentation describes more than one primary flow, one of which is xChange, an atomic RFQ with an execution window of about 60 seconds where the quoted price is the execution price, and a spread that widens in extended hours
Binance bStocks	BEP-20 on BNB Chain, with BEP-677 / Scaled UI Amount support	Described as 1:1 with a regulated custodian / broker-custodian (specific custodian not named in materials reviewed)	ADGM; certificate representing certain financial instruments (FSMR para 92, Schedule 1); BTech Holdings as issuer	Public materials describe a 1:1 zero-fee conversion between bStocks and supported underlying equities purchased through Nest Trading Limited, subject to product terms and eligibility — a venue-internal channel relevant to alignment; the market-maker / eligible-participant arbitrage mechanics behind it are not detailed in the materials reviewed and should be checked in issuer / venue documentation
Ondo Global Markets	ERC-20 / SPL	Disclosed broker / custody / security-agent structure involving Alpaca, BitGo, and Ankura Trust	BVI SPV; tokenized note / tracker structure; Reg S	Reference pricing via SyntheticSharesOracle, with a separate quote price generated from inventory and market conditions and guaranteed for roughly 30 seconds. Primary minting and redemption runs 24/5 for supported assets and, since 25 June 2026, around the clock for a per-asset subset (six at launch, 26 listed in issuer documentation at the time of writing), subject to per-asset session limits the issuer publishes and to wider off-hours spreads
Dinari dShares	ERC-20	Brokerage-account-based backing; Alpaca shown in Dinari docs; other arrangements per issuer documentation	Reg S restrictions; Dinari disclosed as SEC-registered transfer agent; broker-dealer / subsidiary details per issuer documentation	Broker/custody/issuance structure disclosed; operational arbitrage details should be checked in issuer docs
Robinhood Stock Tokens (July 2026)	ERC-20 on Robinhood Chain	Underlying shares held 1:1 by a US-based licensed custodian, monitored daily	Jersey issuer (Robinhood Assets (Jersey) Limited); tokenized debt security under Base Prospectus; Reg S	Primary market runs through Authorised Participants (KYB-vetted), with holder redemption via issuer KYC; per-asset Chainlink price feeds; DEX liquidity on Robinhood Chain (a dedicated Uniswap AMM among the launch venues) — operational arbitrage details per issuer and venue documentation
Robinhood Classic Stock Tokens (EU app)	Platform balance	—	Derivative contract (per Robinhood disclosures)	Platform-internal pricing; no permissionless on-chain arbitrage loop

Robinhood Classic Stock Tokens (the EU app product) are the useful contrast at the bottom: a platform-internal price experience is not the same as an on-chain token with an external arbitrage loop. The other rows involve on-chain token forms with disclosed issuer, custody, and issuance (or, for bStocks, venue-conversion) structures. Issuer-approved issuance, redemption, brokerage, pricing, conversion, or custody channels can matter for alignment, but whether and how the tokens can be transferred, redeemed, converted, or accessed depends on each issuer’s documentation. The last is a closed platform balance with no on-chain loop at all. Note that the same brand appears twice in the table for that reason: Robinhood’s July 2026 Stock Tokens sit in the on-chain rows with their own feed and issuance structure, while the Classic EU app product is the closed-platform contrast; the two products are distinguished in Robinhood Stock Tokens: What You Hold and What You Can Withdraw.

The table is intentionally narrow: it shows why alignment loops differ by structure, not which issuer is safer or more efficient. Issuer failure, shareholder rights, and custody risk are covered in the issuer-failure recovery reference, not here.

Why arbitrage narrows gaps but does not erase them

Arbitrage is good at making gaps small. It cannot make them disappear, because the loop runs into five structural constraints:

• Market-hours constraint. Hedging against the underlying generally tracks US market hours, and many creation / redemption routes are most directly constrained when the underlying market is closed. This is no longer uniform: xStocks documents 24/5 issuance and redemption, while Ondo has run around-the-clock minting and redemption since 25 June 2026, enabled asset by asset rather than across its whole roster. Even where the primary channel stays open, the underlying-share market and the hedge leg still impose practical limits, which is why the issuer that keeps the channel open also publishes conservative off-hours size limits.
• Issuer-channel constraint. Mint/redeem access has its own schedule, capacity, and eligibility rules; the channel is not infinite or instant. Ondo’s public status page makes the capacity side unusually concrete: in a 26 August 2026 snapshot it listed 444 assets, 443 of them available in the regular session but only 26 in the weekend off-hours session, with per-asset maximum trade sizes disclosed per session and most assets showing no off-hours capacity at all.
• Inventory and hedging constraint. Participants can only carry so much exposure; deep or one-sided gaps exceed what inventory and hedging comfortably absorb.
• Reference-price constraint. When the underlying market is closed, the reference prices the loop relies on are themselves estimates, which limits how confidently anyone can quote against them.
• Liquidity-depth constraint. A thin on-chain pool means even a willing arbitrageur moves the price against themselves, so the gap is only partly closed. This constraint binds where the trade crosses a pool; where flow is filled by market makers quoting off issuer mint/redeem access, on intent-based venues and RFQ routes, the binding constraints are their inventory and the issuer-channel limits above rather than pool depth.

A concrete, disclosed example of “narrow but not erase” comes from the issuer side. Ondo describes off-hours buys and sells as quoted, minted, and redeemed instantly, just as they are during regular hours, and documents in the same place that bid-ask spreads can be wider off-hours, that each asset carries its own conservative off-hours limit, and that individual quote requests may be declined until that limit frees up. Its published session limits show the same shape: in the 26 August 2026 snapshot, a large-cap name such as AAPLon carried a $3M maximum trade size in the regular session against a $1M maximum net notional off-hours. The mechanism tightens the gap; it does not guarantee a perfect match.

What happens to the price you see when these constraints bind — the off-hours dislocations, the moves that reverse at the next open, the liquidation risk — is covered in Why 24/7 Tokenized Stocks Do Not Mean 24/7 Price Discovery. This reference stops at the mechanism’s ceiling; that one picks up the consequences.

What this means for self-custody users

The practical takeaway is not “avoid trading off-hours.” It is about reading the price correctly:

What you can buy or sell as a wallet holder is a secondary-market token price. It is not the issuer’s creation/redemption price, and it is not necessarily the underlying stock’s real-time price. Most of the time these sit close together, because the alignment loop is running. When the loop is constrained — off-hours, on a thin chain, around an event — the secondary-market price you transact at can sit further from the underlying than it looks.

Holding the token in self-custody does not change this mechanism; it changes who can move the token afterward. Self-custody wallets such as DeGate can let a holder, where supported, keep a permissionless tokenized asset and move it on-chain. That changes control and mobility; it does not change how the token’s price is aligned.

FAQ

Who arbitrages tokenized stocks? Primarily professional market makers, issuer-side partners, and, where a product defines that role formally, authorized participants — participants with creation/redemption access, inventory, and hedging capacity. Ordinary wallet holders generally trade the token in the secondary market rather than running the full loop.

If I see a price gap, can I arbitrage it myself? Usually no, though the reason has shifted. Primary access itself is no longer market-maker-only: xStocks documents retail redemption subject to KYC and a $5,000 minimum, and Ondo documents a $1 minimum for onboarded, eligible non-US users. What most wallet users still lack is the rest of the loop, namely underlying-market access for the hedge leg, inventory, and the latency budget to act inside a quote window measured in tens of seconds. A visible gap is more often a sign of a constrained loop than a free trade.

Does arbitrage guarantee tokenized stocks match the stock price? No. Arbitrage narrows gaps but cannot erase them. Market hours, issuer-channel limits, inventory and hedging capacity, reference-price behavior, and liquidity depth all cap how tightly the price can be held to the underlying.

Why does issuer redemption matter for tokenized stocks? Issuer issuance, redemption, conversion, or reference-pricing channels link the on-chain token to the off-chain asset exposure. They let eligible participants move exposure through documented routes and close gaps. If that channel is constrained by hours, by per-asset size limits, or by eligibility rules, the most direct path for arbitrage narrows.

Do Binance bStocks change the arbitrage loop? They add a venue-supported conversion channel. Public materials describe a 1:1 zero-fee conversion between bStocks and supported underlying equities purchased through Nest Trading Limited, subject to product terms and eligibility. That channel is relevant to alignment, but the public materials reviewed here do not fully detail the market-maker or eligible-participant arbitrage mechanics behind it, which should be checked in issuer / venue documentation.

Are DEX prices and issuer reference prices the same? Not necessarily. A DEX secondary-market price is set by on-chain supply, demand, and liquidity depth, or, on intent-based venues, by the market-maker quote that fills the order; an issuer reference or redemption price is tied to the underlying through issuer methodology and eligible channels. The alignment loop is what keeps the two close — when it is constrained, they can diverge.
