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 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 channels, inventory, hedging, and reference-pricing mechanisms, not because the token “knows” the stock price. Most users see the result, not the loop. And the loop 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, authorized participants, and issuer-side partners. 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 channel. A participant needs access to the issuer’s permitted creation/redemption channel — the route that links the on-chain token to the off-chain share exposure, cash settlement, or reference mechanism, depending on the product. This is the core of the loop.
• 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:

• No authorized mint/redeem access. Issuer creation/redemption is generally available to permitted participants, not to any wallet.
• 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.
• 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.

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	Market makers / permitted participants are described in issuer / venue documentation as part of secondary-market support; operational details remain subject to issuer 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. Binance’s Ondo FAQ describes near-instant minting/redemption linked to the underlying market, which can help arbitrage bring prices back in line; spreads still exist and large orders may face wider 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 EU stock tokens	Platform balance	—	Synthetic derivative contract	Platform-internal pricing; no permissionless on-chain arbitrage loop

Robinhood EU stock tokens 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 first three involve on-chain token forms with disclosed issuer, custody, and issuance structures. Issuer-approved issuance, redemption, brokerage, pricing, or custody channels can matter for alignment, but whether and how the tokens can be transferred, redeemed, or accessed depends on each issuer’s documentation. The last is a closed platform balance with no on-chain loop at all.

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. Creation, redemption, and hedging against the underlying generally track US market hours; the underlying market is closed on weekends and US holidays. When that side is closed, the loop’s most direct path is narrowed.
• Issuer-channel constraint. Mint/redeem access has its own schedule, capacity, and eligibility rules; the channel is not infinite or instant.
• 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.

A concrete, disclosed platform-side example of “narrow but not erase” comes from Binance’s FAQ on the Ondo tokenized securities it offers: near-instant minting and redemption linked to the underlying market lets arbitrage bring prices back in line, and a bid-ask spread still exists, with larger orders potentially facing wider spreads. 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, authorized participants, and issuer-side partners — 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. The full loop typically requires issuer-approved mint/redeem channels, inventory, hedging capacity, and underlying-market access that most wallet users do not have. 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-approved issuance, redemption, or reference-pricing channels link the on-chain token to the off-chain asset exposure. They let permitted participants move exposure through issuer-approved routes and close gaps. If that channel is constrained or closed, the most direct path for arbitrage narrows.

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; an issuer reference or redemption price is tied to the underlying through issuer methodology and permitted channels. The alignment loop is what keeps the two close — when it is constrained, they can diverge.
