ARB climbed nearly 20% over the past week and touched an intraday high of $0.094 after Robinhood Chain, a new Layer 2 network built with Arbitrum technology, began operating on July 1 in London. The launch drew attention because it activated a revenue-sharing provision that sends part of the new network’s income back into the Arbitrum ecosystem.
The move gives Arbitrum a major corporate-backed chain using its infrastructure at a time when Layer 2 networks are under pressure to prove they can generate durable revenue, not just transaction activity. Robinhood Chain was built with Arbitrum Orbit, a framework that allows projects to launch customized blockchains connected to the broader Ethereum scaling ecosystem.
The immediate market reaction was driven less by Robinhood Chain’s current revenue and more by what it could become if Robinhood shifts a large share of its stock tokenization and crypto activity onto the new network. Robinhood reported about $324 billion in total assets and $143.6 billion in custodial holdings, giving the chain a potentially large base of financial activity if adoption deepens.
Johann Kerbrat, Robinhood’s head of international and crypto operations, recently said the new network is intended to help bring everyday financial assets onto public blockchain infrastructure. That goal follows a strong year for the company’s digital asset business, after Robinhood reported $358 million in crypto-related revenue for 2024.
Revenue-sharing rule returns to focus
The central mechanism behind the renewed attention is the Arbitrum Expansion Program, known as AEP. Under the program, chains created with Arbitrum Orbit that settle outside Arbitrum One or Arbitrum Nova must share 10% of net protocol income with the Arbitrum ecosystem.
Of that amount, 8% is directed to the ArbitrumDAO Treasury, while 2% goes to the developer guild. The rule does not apply to chains that settle within Arbitrum, such as Xai or Sanko. In practice, the structure is designed to let Arbitrum benefit when outside teams use its technology to build new networks that operate beyond its main chains.
Until Robinhood Chain launched, the rule had limited impact because there were few large external networks using the model at meaningful scale. Robinhood’s entrance changed that perception. Even though the current revenue numbers remain modest, the size of Robinhood’s user base and asset platform gives the arrangement more commercial weight than earlier examples.
The AEP structure also gives the ArbitrumDAO Treasury a possible source of recurring income. That matters because decentralized treasuries often rely heavily on token holdings, grants, and governance-controlled reserves. A recurring share of protocol income could create a more business-like funding stream for ecosystem development, though the scale remains unproven.
Early network activity is strong, but revenue is still limited
Robinhood Chain recorded more than 17 million transactions within slightly more than one week of launch, according to figures shared by Johann Kerbrat. The network also reached 350,000 unique addresses, $2.5 billion in total value locked, and more than $1 billion in decentralized exchange volume.
Those figures are large for a new Layer 2 network. They show that Robinhood Chain is already processing meaningful activity and has attracted liquidity quickly. The high transaction count also suggests that the chain is being used for more than a simple brand announcement or limited technical test.
However, the revenue data tells a more cautious story. According to Dune data cited in the market discussion, Robinhood Chain’s protocol revenue was only about $146,000 during the early period. After settlement costs on Ethereum Layer 1, the remaining net amount was roughly similar.
That means the actual revenue flowing to Arbitrum through the AEP is still small. A 10% share of net protocol income only becomes material if Robinhood Chain continues to grow, raises fee volume, and supports higher-value activity over time.
For traders, this distinction is important. Strong network activity can support a narrative, but treasury income depends on net protocol revenue, not just transactions, addresses, or total value locked. A chain can process millions of low-cost transactions while producing only limited income if fees are low or settlement costs remain high.
Tokenized stocks could be the bigger opportunity
The larger question is whether Robinhood’s tokenized stock offering eventually moves onto Robinhood Chain at scale. Robinhood already offers more than 2,000 tokenized stocks across 120 countries. If those assets are migrated or deeply integrated with the new chain, the revenue base for AEP could expand substantially.
Tokenized equities are different from many crypto-native use cases because they are connected to familiar financial products. If ordinary stock trading, settlement, transfers, or collateral activity begins flowing through a public or semi-public blockchain environment, the resulting fee base could be more stable than activity driven only by speculative crypto cycles.
That is the broader market story behind the ARB rally. Traders are not simply reacting to one week of chain data. They are weighing whether Robinhood Chain could become a venue where traditional financial assets, tokenized stocks, crypto trading, and decentralized liquidity meet.
Still, several questions remain unresolved. Robinhood has not yet demonstrated that most of its tokenized stock activity will shift to the new chain. Regulatory treatment may vary across regions. User adoption may also depend on whether customers notice meaningful benefits, such as faster settlement, extended trading access, lower costs, or improved collateral use.
Comparison with Optimism’s model
Arbitrum’s AEP resembles the revenue-sharing model used by Optimism through the OP Stack. Optimism has long collected fees from affiliated chains, including Base, Zora, and Mode. Its model has included either 2.5% of sequencing income or 15% of net profits, depending on the arrangement.
That approach helped establish the idea that Layer 2 software stacks can become revenue-generating platforms. Instead of earning only from a single chain, a technology provider can collect income from a network of chains built with its tools.
But the Optimism example also shows the risk. Optimism’s collective revenue has been falling, reaching around $2.9 million in the first quarter of 2026, down 21.5% from the previous quarter. Around $1.4 million of that amount came from Base, making Base a central contributor.
In February, Base announced plans to leave the OP Stack. That decision removed a major source of expected income for Optimism’s treasury and put pressure on the OP token, which fell 28% over two days after the announcement.
The Base episode is now part of the debate around Robinhood Chain and Arbitrum. If a large corporate-backed chain becomes successful, it may eventually decide that running independently is more attractive than continuing to share income under an external framework.
Could Robinhood Chain eventually split away?
Some market observers have raised the possibility that Robinhood Chain could one day separate from Arbitrum Orbit, similar to Base’s planned departure from the OP Stack. There is no confirmation that Robinhood plans such a move, but traders are watching the possibility because it could affect expectations for future AEP income.
The concern is simple. If Robinhood Chain becomes highly profitable while paying a share of net protocol income to Arbitrum, Robinhood may eventually consider whether it can lower costs or gain more control by using a different technical setup. That does not mean a separation is likely in the near term, but it is a risk that becomes more relevant as the chain grows.
For now, the current structure benefits Arbitrum. It gives the ecosystem a high-profile external participant and validates Arbitrum Orbit as a technology used by a major financial platform. Robinhood also benefits by launching with mature Layer 2 infrastructure instead of building every component from scratch.
The balance between those benefits will be tested over time. If the partnership remains productive, AEP could become a meaningful part of Arbitrum’s economic model. If Robinhood eventually exits, ARB could face the same kind of sentiment shock that affected OP after Base’s announcement.
Sequencer revenue becomes a key metric
Daily sequencer revenue is one of the most important figures to watch as Robinhood Chain matures. Growthepie data show that Robinhood Chain’s daily sequencer revenue has reached nearly $60,000. That places it second among Ethereum Layer 2s behind Base, which recorded about $72,000, and roughly triple the level of Arbitrum’s own main chain.
Sequencer revenue matters because Layer 2 networks collect fees when they order and process transactions before settling data back to Ethereum. A chain with high sequencer revenue may be building a real business around transaction flow.
Still, gross sequencer revenue is not the same as net income. Layer 2 networks must pay costs, including data availability and settlement fees on Ethereum. What matters for AEP is net protocol income after relevant expenses.
Robinhood Chain is also the second-largest user of Ethereum data availability after Base. It pays fees in ETH for blob transactions, and those fees are permanently burned under Ethereum’s fee mechanics. This creates an important economic link between Robinhood Chain and Ethereum itself.
That link has led some observers to argue that Robinhood Chain may be more directly aligned with ETH than with ARB in certain respects. The chain currently sends a share of net income to Arbitrum’s decentralized treasury, but its settlement activity also supports Ethereum’s fee burn. In other words, the network’s growth can have different effects across the Ethereum ecosystem.
What the ARB rally really reflects
The ARB price move reflects a shift in how traders are valuing Layer 2 tokens. In earlier cycles, Layer 2 tokens often traded on expectations of user growth, governance power, or general ecosystem development. The Robinhood Chain launch has brought a sharper focus to cash flow.
If Arbitrum can collect recurring revenue from external chains, ARB may increasingly trade on expectations around ecosystem income and treasury growth. That does not mean ARB functions like a stock or pays dividends. The AEP revenue goes to the ArbitrumDAO Treasury and developer guild, not directly to token holders.
However, a stronger treasury can still matter. It can fund grants, infrastructure, developer incentives, liquidity programs, and ecosystem expansion. Over time, those programs may influence network demand and token sentiment.
The comparison to equity-like value remains imperfect. ARB holders do not automatically receive cash distributions. Governance decisions determine how treasury resources are used. The value of AEP revenue depends on how effectively the ArbitrumDAO allocates it.
Layer 2 networks are becoming businesses
The Robinhood Chain launch adds to a broader trend: Layer 2 systems are moving from technical scaling experiments into commercial platforms. They are competing not only on speed and transaction costs, but also on distribution, revenue, application ecosystems, and partnerships.
Arbitrum remains one of the largest Layer 2 ecosystems by total network value, with more than $15 billion secured across its ecosystem, while its closest rival holds roughly $12 billion in locked assets. Those figures show that the largest Layer 2 networks have become major financial venues in their own right.
Corporate-backed chains can accelerate that trend. A platform such as Robinhood brings an existing customer base, brand recognition, and regulated financial product experience. That gives Robinhood Chain a different profile from many crypto-native networks that must build demand from the ground up.
The challenge is sustainability. Early launches often produce high activity because of incentives, curiosity, and concentrated attention. The real test comes after the first wave, when users decide whether the chain offers enough value to keep returning.
Risks remain despite the strong start
The main risk for ARB is that expectations may move faster than actual revenue. Current protocol revenue from Robinhood Chain is still small relative to the scale of the market reaction. If activity slows or fees remain low, the AEP contribution may disappoint traders who expect a rapid increase in treasury income.
Another risk is dependence on one high-profile partner. Robinhood’s entrance gives Arbitrum a major boost, but it also means the market may become sensitive to any sign of strain in the relationship. Rumors of a future separation, changes in technical design, or adjustments to the revenue-sharing model could create volatility.
Regulation is another factor. Tokenized stocks operate closer to traditional securities markets than many crypto assets. Cross-border access, settlement rules, custody standards, and disclosure requirements may all affect how quickly Robinhood can expand tokenized products on-chain.
There is also competition. Base remains the strongest benchmark for corporate-backed Layer 2 activity, with hundreds of thousands of daily active users and leading sequencer revenue. Newer platforms must show they can match that level of sustained demand, not just capture launch-week attention.
What traders are watching next
Traders are likely to focus on daily active addresses, sequencer revenue, decentralized exchange volume, settlement costs, and total value locked in the coming weeks. The key question is whether Robinhood Chain can maintain activity after its launch period and convert that usage into meaningful net protocol income.
If tokenized stock activity grows on the chain, the AEP revenue base could become more important for Arbitrum. If usage remains mostly limited to early crypto activity, the impact may be smaller than the market currently expects.
For now, Robinhood Chain has given Arbitrum something it lacked: a large external participant that can test whether its expansion program works at commercial scale. The ARB rally shows that traders see the possibility of a new revenue channel. The next phase will show whether that possibility becomes a lasting source of income for the Arbitrum ecosystem or another short-lived Layer 2 narrative.
