Robinhood built its own chain, but a portion of the revenue still goes elsewhere. Every dollar Robinhood Chain earns, 10% goes to the Arbitrum ecosystem under a structure that has often been presented as positive for $ARB holders. The less discussed question is what a licensed brokerage that spent years arguing for fewer intermediaries actually bought by becoming a tenant on another network.

The irony is difficult to miss. Robinhood spent a decade telling retail investors that the layers between them and the market were extractive, that commissions acted like a tax on participation, and that fewer intermediaries was the better architecture. On July 1, it launched its own blockchain — a settlement layer it controls, sequences, and uses to collect fee revenue. Yet under the technology stack it chose, a tenth of what that chain nets goes to someone else.

Specifically, 8% goes to a treasury controlled by governance token holders, and 2% funds a developer guild, both under the Arbitrum Expansion Program. The structure has been discussed repeatedly since Offchain Labs disclosed it, usually from one angle: what it means for $ARB, why the token rallied, and how a governance asset gained exposure to chain revenue. This report asks a different question: what exactly did Robinhood buy, what is it paying, and does the math work?

What the arrangement is

The mechanics matter, and they have often been described loosely.

The Arbitrum Expansion Program applies to any Layer 2 or Layer 3 chain built with Arbitrum’s Orbit toolkit that settles outside Arbitrum One or Arbitrum Nova. Such chains route 10% of net protocol revenue back to the Arbitrum ecosystem. Of that amount, 8 percentage points go to the Arbitrum DAO treasury, controlled by $ARB tokenholders through governance, and 2 percentage points go to the Arbitrum Developer Guild, which supports tooling, grants, and protocol work.

Three details are especially important and often omitted:

• Net, not gross. The payment is based on revenue remaining after network operating costs, which ties the fee share to actual profitability rather than raw transaction volume. That is materially better for an operator than a gross-revenue split and means a thin-margin chain pays little even if activity is high.
• Sequencer profits are the base. The shared revenue comes from the entity that orders and processes transactions. On Robinhood Chain, that entity is Robinhood. This is the same revenue line often treated as the core economics of a Layer 2.
• MEV may be included. If the chain adopts Timeboost, Arbitrum’s mechanism for capturing maximal extractable value from transaction ordering, those revenues could also fall under the sharing arrangement. Whether Robinhood adopts it is a live question with real economic implications, especially for a chain hosting tokenized equities.

For comparison, Arbitrum One sends 100% of its own fees to the Arbitrum treasury. The Orbit arrangement is lighter, and that is the point: it is the price of using the stack without settling on the flagship chain.

The numbers so far

For the first three weeks, the arrangement remained largely theoretical. It does not anymore.

Robinhood Chain has surpassed $2 million in cumulative revenue since its July 1 launch, with about $200,000 routed to the Arbitrum ecosystem under the program. That is a straightforward 10%, and it is the first clear confirmation that the mechanism works in practice rather than only on paper.

Several throughput figures help explain those numbers. The chain processed roughly 4 million transactions in its first week. Uniswap alone recorded $500 million in 24-hour volume on the chain. A single day in early July cleared $568 million. Within about two weeks, daily decentralized exchange volume exceeded $800 million, briefly surpassing Ethereum’s, with roughly $3.9 billion across a week. Arbitrum said the network earned more than $800,000 in revenue across seven days, which annualizes to about $42 million. Deposits crossed $600 million this week, rising 50% over seven days.

There is an important distortion to apply here. Robinhood Chain is running a 90-day gas subsidy that expires around October, which means users are not paying the fees a mature chain would charge and revenue is being suppressed accordingly. An audit of the chain’s first month documented how strongly that subsidy inflates activity metrics; the same subsidy works in the opposite direction on revenue. The $42 million annualized figure is therefore both real and a floor. The more meaningful read will come after the subsidy ends, when volumes and revenue reprice.

At current run rates, Arbitrum’s share is roughly $4 million a year. Against Robinhood’s quarterly revenue of about $1.27 billion, that is immaterial. Against the chain’s own economics, it is 10% of everything.

What Robinhood bought

The structure looks strange only if the alternative is assumed to be free. It was not.

Build independently

A brokerage could commission a chain from scratch, keep 100% of sequencer revenue, and pay no share to anyone. The tradeoff is time, engineering risk, and security. Building a settlement layer means auditing it, defending it, and answering for it if something breaks — a nontrivial exposure for a regulated financial firm holding customer assets. It also means starting without an ecosystem: no existing tooling, no bridges, and no wallets that already work.

Use an existing chain

A company can deploy on Arbitrum One, Base, or another chain, pay standard fees, and capture nothing. Robinhood initially did something close to this, launching tokenized stock offerings on Arbitrum in 2025 before committing to its own chain. The limitation is obvious: the company would be a tenant with no control over the roadmap, fee schedule, or who else is building next door.

Take the Orbit path

The middle option is to launch a branded chain, keep control of sequencing, and rely on Offchain Labs for technical support while inheriting Arbitrum’s tooling and security assumptions — in exchange for 10% of net revenue. The launch details suggest what that bought: 100-millisecond block times, EVM compatibility, $ETH as the gas asset instead of a new token, and a chain live and processing millions of transactions within a week of announcement.

Seen this way, the 10% is a build-versus-buy decision that favored speed. For a public company with a stock to defend and a crypto revenue line that fell 47% year over year in the first quarter, speed may have been worth more than margin.

The less comfortable interpretation is that Robinhood concluded ownership of the rails is where the value sits — but it still does not fully own those rails. Instead, it leases them from a decentralized organization whose token holders vote on how the proceeds are used.

The tenant problem

That is not just rhetorical flourish. It describes a governance relationship with consequences that are easy to overlook.

The 8% directed to the Arbitrum DAO treasury is controlled by $ARB tokenholders through governance votes. Those same tokenholders also influence the direction of the technology stack Robinhood Chain depends on. A federally regulated brokerage is now both a revenue contributor to, and a dependent of, an entity governed by token voting from anonymous participants.

For most crypto-native businesses, that is unremarkable. For a public company that files with the SEC, answers to a board, and holds customer assets under regulatory obligations, it is a novel counterparty structure. The practical questions are clear: what happens if governance votes to change the fee arrangement, what recourse exists if the stack’s roadmap diverges from Robinhood’s needs, and how a regulated institution documents reliance on a DAO in its risk disclosures.

There is also a competitive issue. The Orbit program is open on the same terms to anyone else. The arrangement Robinhood entered is not exclusive and gives it no advantage over the next brokerage that decides to build a chain. That limits the size of any moat, though it does create a template. The broader tokenized-equity race is already moving: Nasdaq is building blockchain share issuance with Kraken’s parent, and ICE is working with OKX, none of which requires anyone to start from scratch.

Does the arithmetic work?

Set aside the framing and ask the commercial question.

Roughly $42 million in annualized chain revenue, before the subsidy expires, against $4 million to Arbitrum. Against Robinhood’s quarterly revenue near $1.27 billion, the chain contributes only a low single-digit percentage of annual revenue at current run rates, and the Arbitrum payment is immaterial to the parent.

That means the fee share is not the story financially. It is the story structurally, because it clarifies what the chain really is. Robinhood did not build a chain to earn sequencer fees; those numbers are too small relative to its brokerage business. It built one to control the settlement layer for tokenized equities, avoid dependence on another company’s infrastructure as the market develops, and own the venue where its own products trade. Sequencer revenue is a byproduct, and 10% of a byproduct is a reasonable price for the option.

The test comes when the byproduct stops being small. If tokenized equities scale the way the DTCC’s involvement suggests they might, and if Robinhood Chain captures a meaningful share of that activity, sequencer revenue grows and the 10% grows with it. A tenth of a rounding error is nothing. A tenth of a business is a negotiation, and the terms were written by the party that set them.

The precedent this sets

Stripped of the company names, the arrangement reflects a broader industry direction: infrastructure providers taking a percentage of businesses they do not operate.

Under this model, Arbitrum looks less like a traditional blockchain and more like a franchise operator. It supplies the technology, tooling, security assumptions, and developer support, then takes a percentage of what franchisees earn across a growing set of chains it did not build. Offchain Labs has been explicit that this is the strategy, describing enterprise adoption as the revenue thesis while treating the flagship chain’s economics separately. The model compounds as adoption grows, unlike grants or one-time licensing fees.

That is obviously attractive to anyone holding the governance token. It also has a less obvious consequence for builders: a percentage deal agreed at launch, when the tenant is small and the terms are favorable, can become expensive precisely when the tenant succeeds. Ten percent of nothing costs nothing. Ten percent of a settlement layer that hosts a significant share of tokenized equities becomes a real line item — one collected by a party whose consent was needed at the start and whose terms the tenant did not write.

The closest comparison outside crypto is the app store. Developers accepted a percentage when the platform was small and the alternative was no distribution, then spent the next decade in litigation and regulatory complaints over the rate. The Arbitrum arrangement is not coercive in the same way, since alternatives exist and the terms are public. But the structural shape is familiar, and history suggests platform percentages are eventually renegotiated by the largest tenants.

Robinhood is now among the largest tenants on this platform. Whether it eventually acts like one is a question for the quarter after the subsidy expires, when the numbers stop being easy to ignore.

What to watch

• Revenue after October. The 90-day gas subsidy should expire around then, making the first unsubsidized quarter the cleanest view of what the chain actually earns.
• Whether Timeboost is adopted. MEV capture on a chain hosting tokenized equities could be meaningful, and adopting Arbitrum’s mechanism would likely bring that revenue into the sharing arrangement.
• Disclosure in filings. It will be important to see whether Robinhood describes the Arbitrum arrangement in its regulatory filings as a dependency or risk factor, and how it does so.
• Whether the terms hold. The Expansion Program’s rates are set by Arbitrum governance, and any proposal to change them would test how much leverage a large Orbit tenant really has.
• Competitors taking the same path. Any brokerage can use the same structure on the same terms, so the larger question may become what Arbitrum collects from an entire category it does not directly operate.

A final point: most of the existing coverage of this arrangement was written for holders of a governance token, so the focus was naturally on whether the revenue share justified a rally. That is a legitimate question, but it also leaves out the other side of the deal. The side that matters here includes the public company, the regulatory filings, the customer assets, and the board.

Robinhood’s chain is now a material part of its strategic story. Its stock trades on that story, and the chain’s economics include a standing obligation to an entity that many securities analysts would not otherwise have to track. That gap between how crypto covers a deal and how equity markets would cover the same deal is where some of the most useful analysis in the sector now sits. Every ecosystem announcement is worth reading with the question of who else is party to it.

The same platform-ownership pattern is also visible in prediction markets, where distribution, licensing, and customer ownership intersect.
