Is Arbitrum (ARB) now a claim on Robinhood Chain's cash flow? That is the question traders paid for between 31 August and 7 September, when ARB's daily price on CoinGecko went from $0.0842 to $0.1893. Read the licence terms and the fee ledger and the answer is yes, but a thin claim, and a shrinking one. Robinhood Chain pays 10% of its net protocol revenue under the Arbitrum Expansion Program, and eight of those ten points land in the ArbitrumDAO treasury. On 4 September the DAO's share came to $489,557 for the day, according to DefiLlama. On 12 September it was $64,274, a fall of 86.9%. ARB traded at $0.1367 at 13:39 UTC on Sunday 13 September, 27.8% below its 7 September close. The fee line fell three times as far as the token did.
That gap is what the market has not priced. Take one day of the DAO's income (the 8% licence share, Arbitrum One's own gas fees and Timeboost auction proceeds), multiply by 365 and set it against ARB's fully diluted value. On 4 September the token traded at about 7.6 times that run-rate. On 12 September it traded at about 49 times, with the price almost unchanged between those two mornings. ARB is dearer on its own income now than at the top of the rally. None of that income goes to holders, either: it accrues to a treasury that sent 230 million ARB to the Arbitrum Foundation in July, and another 92.65 million ARB vest to team, contributors and investors on Wednesday.

How a Robinhood Chain dollar reaches the ArbitrumDAO
Robinhood Chain went live on public mainnet on 1 July as a dedicated Arbitrum chain that settles to Ethereum rather than to Arbitrum One. That settlement choice is what puts it inside the licence. According to the ArbitrumDAO factsheet on the launch, chains deployed outside Arbitrum One pay 10% of protocol net revenue for the technology, with 8% going to the DAO treasury and 2% to the Arbitrum Developer Guild. The code descends from a 2018 Princeton paper, "Arbitrum: Scalable, private smart contracts", whose five authors included Ed Felten and Steven Goldfeder.
Net is the word that matters. DefiLlama's methodology for Robinhood Chain defines revenue as gas fees minus Ethereum L1 execution and blob costs, so the licence fee moves one-for-one with the chain's gas bill. The data agree with the Foundation's own accounts: DefiLlama's July total for the full 10% licence line is $357,227, and the Foundation's H1 report puts July licence fees at $360,000, 35% of DAO income that month.
Brendan Ma, Head of Investment Strategy at the Arbitrum Foundation, said in the 2 September report: "On July's figures, total income for the third quarter is already on track to exceed the second quarter by more than 40%." He based it on July, before the surge in Robinhood Chain fees that began in the last days of August, and on the dollars involved it is modest. The first half brought in $6.19m in total.
The money stops at the treasury. The Foundation's 2027 funding proposal lays out the circuit plainly: revenue accrues to the DAO, while the Foundation, which pays the running costs of Arbitrum One and Nova, returns to the DAO periodically to ask for money. No burn exists and no buyback is running. When a holder opened a forum thread on 16 August titled "Is ARB Intended to Remain Primarily a Governance Token Long Term?", it was still an open question.
The fee boom's effect on the chain's main exchange is a separate trade, covered in our Uniswap (UNI) analysis. This piece follows the other pipe, the one that runs to ARB.
Eight days of fee data against a week of price
ARB's returns depend heavily on the anchor date, so here they are with the dates, all from CoinGecko daily prices at 00:00 UTC against the 13:39 UTC spot. From the 14 August price of $0.0752 the token is up 81.8%. From the lowest close in the past year, $0.0727 on 16 August, it is up 87.9%. Against 6 September ($0.1776) it is down 23.1%, and against 14 September 2025 ($0.5417) it is down 74.8%. The intraday top in CoinGecko's hourly series was $0.2024 at 08:00 UTC on 6 September. CoinGecko's own headline percentages (−28.0% over seven days, +83.7% over 30) do not reconcile with those daily prices, because they measure from a rolling timestamp.
The peers help frame it. Ether rose 31.5% over the same 30 days, from $1,884 to $2,478, a move covered in our ETH August review. Optimism's OP token, the nearest rollup comparison, gained 8.0% and is down 88.3% over the year. ARB's September jump was specific to Arbitrum, and so is the unwind.
The table puts the fee collapse next to the price, day against day.

| Robinhood Chain gas fees | $6,044,224 | $804,007 | −86.7% |
| Licence fee, full 10% of net revenue | $611,946 | $80,342 | −86.9% |

Sources: DefiLlama fees and revenue series for Robinhood Chain, Arbitrum Nitro, Arbitrum and Arbitrum Timeboost; CoinGecko daily prices. All retrieved 13 September 2026. Annualised income adds the DAO's 8% share, Arbitrum One gas fees and Timeboost ($449 and $178 on the two days) and multiplies by 365.
A single day is a noisy base. The seven days to 12 September still produced only $772,363 for the DAO, or about $40m a year. Price has come down a long way, but not as far as income.
The supply that arrives regardless
ARB's unlock schedule is written into the Foundation's token-supply page. Team, contributor and investor allocations total 4.447bn ARB. A quarter vested on 16 March 2024, and the remaining 3.335bn release in 36 monthly tranches of about 92.65m. The tranche due on Wednesday 16 September is the 30th. Counting it, seven remain, 648.5m ARB in all, or about $88.6m at today's price, with the last in March 2027. The Foundation's own figure is 0.77bn ARB still vesting as of 17 August, a total that also includes its linear allocation.
One tranche is worth about $12.7m at spot. The DAO's licence income for the most recent week was $772,363.
The treasury is the larger overhang, and it is not hypothetical. A direct read of the ARB contract on Arbitrum One shows 2,556,141,992 ARB in the DAO Treasury address. CoinGecko counts 6.678bn ARB as circulating, which leaves 3.322bn outside, almost exactly the treasury balance plus the unvested tranches. Every governance grant therefore moves tokens from the non-circulating column into the float. The July payout did just that: the Foundation received 230m ARB (2.3% of supply, about $31.4m at spot) plus $16m in tokenised real-world assets and 1,740 ETH, executed on 15 July against a 2027 operating budget it forecasts at $27.6m. In the forum thread, delegates asked whether the Foundation would sell. Its reply said it aims to limit market impact on any action involving ARB and can work with financial counterparties and trading desks to do so. That describes how it would sell, which is not the same as saying it won't.
Set the $27.6m budget beside the DAO's actual income: $6.19m in the first half, then a September run-rate that has swung between $185m and $28m a year inside eight days. On the current rate, the Foundation's 2027 budget alone roughly equals a full year of DAO income, with nothing left over for anything that could support the token.
Arbitrum One is not carrying its share
The rally's logic relies on Robinhood Chain because Arbitrum One, the network ARB was issued to govern, has been shrinking. DefiLlama shows Arbitrum One gas fees of $3.22m in October 2025 against $363,291 in August 2026, an 89% fall. Timeboost, the transaction-ordering auction that DefiLlama tracks from April 2025, raised $387,676 for the treasury in January and $41,816 in August. Total value locked on the chain stood at $1.39bn on 13 September, 60.5% below the $3.52bn of a year earlier.

|---|---|---|---|
| Base | $5.55bn | $5.16m | No token |
| Arbitrum One | $1.39bn | $438,031 | ARB −74.8% |
| Robinhood Chain | $0.93bn | $32.9m (net of L1 costs and licence) | No token |

Base, Coinbase's rollup, earns roughly twelve times Arbitrum One's revenue on four times the deposits and pays nothing to any token. Robinhood Chain earns more than both, and ARB's claim on it is the licence line, not ownership. Stablecoins on Arbitrum, which the Foundation cites as a strength, fell from $4.41bn on 10 September to $3.99bn on 12 September in DefiLlama's count. Even the lending on Robinhood Chain, which runs through Morpho according to the DAO factsheet, sits on Robinhood's chain rather than on Arbitrum One. Our Morpho deposits piece tracks that protocol's growth on Base.
Who bought the move, and who is left holding it
Leverage did the lifting. Binance ARBUSDT perpetual open interest rose from 207.0m ARB ($17.4m) on 31 August to 382.5m ARB ($64.8m) on 8 September, an 85% jump in contracts, and has since shed 20% to 306.1m ARB ($43.0m) on 13 September. Funding sat at or near 0.0100% per eight hours through most of 4 to 6 September. Since 7 September it has dipped below zero on several prints, and both of the 13 September settlements were negative (−0.0041% at 00:00 UTC and −0.0098% at 08:00 UTC), meaning shorts paid longs to keep their positions open. CoinGecko shows $117.3m of ARB volume over the past 24 hours.
The next test for the fee line has a date. On 7 August Robinhood Crypto posted on X that it had cut Robinhood Wallet's gas-sponsorship minimum on Robinhood Chain from $5 to $0.50, so that it would cover gas on many more wallet swaps until 29 September. Some of the gas that generated September's licence income was therefore paid by Robinhood, not by traders. Robinhood has not disclosed how much. When the promotion ends, wallet users start paying their own gas, and nobody yet knows how many keep trading. For the equity side of Robinhood's crypto exposure, see our HOOD note.
Positioning, supply and the subsidy calendar all point the same way into late September. The one thing that could reverse them is on-chain activity, and that series updates daily on DefiLlama.
The call: $0.105 base, $0.22 bull, $0.075 bear
We treat ARB as what its documents say it is: a governance token over a treasury whose income is volatile and undistributed. Each level below is the same 35 to 37 times multiple of fully diluted value to annualised DAO income, applied to a different income path. Spot is $0.1367 at 13:39 UTC on 13 September; horizon is 31 December 2026.
RelatedDogecoin (DOGE) Rose 29% in 30 Days on the CLARITY Act Trade
Base case, $0.105 (50%), 23.2% below spot. Robinhood Chain gas settles at roughly $0.8m to $1m a day once the wallet subsidy ends, which leaves the DAO's share near $70,000 a day. Add Arbitrum One and income runs at about $30m a year. The four remaining 2026 tranches land and some Foundation ARB meets the market. At a $1.05bn fully diluted value, that is 35 times income.
Bull case, $0.22 (20%), 61.0% above spot. Fees prove sticky after 29 September and the DAO's share holds above $150,000 a day (about $60m a year with Arbitrum One). Separately, the DAO votes to route licence income into ARB, answering the August forum question. A $2.2bn value on $60m is 37 times.
Bear case, $0.075 (30%), 45.1% below spot. Subsidy expiry cuts Robinhood Chain's gas to about $525,000 a day, the DAO's share drops to about $42,000, and income runs near $20m a year. Price revisits the 16 August lowest close of $0.0727 and the 26 June all-time low of $0.0705.
The probability-weighted value is $0.119, 13% under spot. What would change my mind: a daily close above $0.19, beyond the 7 September peak close, on the 00:00 UTC print. Two weeks of DAO licence income above $150,000 a day after 29 September would also do it, as would an executed proposal that ties treasury income to ARB. Short of those, today's 48 times income multiple has to compress, whether through a lower price or through fees that return.
Arbitrum (ARB): frequently asked questions
Does Arbitrum earn money from Robinhood Chain?
Yes. Under the Arbitrum Expansion Program, Robinhood Chain pays 10% of its net protocol revenue: 8% to the ArbitrumDAO treasury and 2% to the Arbitrum Developer Guild. DefiLlama puts the DAO's share at $2.91m over the 30 days to 12 September. Daily receipts peaked at $489,557 on 4 September and were $64,274 on 12 September.
When is the next ARB token unlock?
The next team, contributor and investor tranche, about 92.65m ARB, is due on 16 September 2026. Under the schedule in the Arbitrum Foundation's token-supply documentation, the unlocks run monthly until March 2027, and seven tranches (648.5m ARB) remain counting September's. The Foundation's own allocation also releases linearly until April 2027.
Does ARB have a buyback or a burn?
No. Income from Arbitrum One fees, Timeboost and licence fees accrues to the DAO treasury, and ARB holders govern how it is used. No proposal routing that income into ARB was in force on 13 September. On 16 August a holder opened a forum thread asking whether ARB is meant to remain primarily a governance token.
What is the Arbitrum price prediction for the end of 2026?
Our base case is $0.105 by 31 December 2026 (50% probability), with a bull case of $0.22 (20%) and a bear case of $0.075 (30%). Spot was $0.1367 at 13:39 UTC on 13 September. A daily close above $0.19 would invalidate the downside lean.
Why did ARB fall after 7 September?
The fee line behind the rally fell fast. Robinhood Chain gas fees dropped from $6.04m on 4 September to $0.80m on 12 September, and the DAO's licence share fell 86.9% with them. Binance open interest also shed 20% from its 8 September peak as leveraged positions closed.
