Interactive Brokers adds ETH staking for clients

TLDR

Interactive Brokers has begun offering Ethereum (ETH) staking to eligible clients via partner Zerohash, adding yield-style rewards on ETH inside its mainstream brokerage platform.

1. Interactive Brokers now lets eligible clients stake ETH in its Client Portal, with Zerohash running validators and rewards paid as additional staked ETH that can compound.
2. Fees on staking rewards are capped at 30%, assets sit in a Zerohash account outside brokerage protections, and availability varies by jurisdiction and account type.
3. This moves Ethereum staking further into traditional finance, and next steps to watch are support for more assets, clearer eligibility lists, and potential regulatory scrutiny of retail staking.

Deep Dive

1. How ETH Staking Works At Interactive Brokers

On 13 October 2026, Interactive Brokers (IBKR) launched Ethereum staking for eligible Interactive Brokers LLC clients, accessible through a new Staking Dashboard in its Client Portal, with infrastructure provided by Zerohash.\ Clients choose how much ETH to stake, submit staking or unstaking requests, and track pending activity through the dashboard; rewards are credited as additional staked ETH, letting balances compound while they remain staked, according to the brokers announcement and coverage such as Finance Magnates and Crypto Briefing. The service currently supports only Ethereum, and it extends IBKRs existing crypto stack, which already includes trading in about 20 digital assets and stablecoin funding via USDC and other tokens, as noted by crypto.news.

2. Fees, Protections, And Key Risks

Under IBKRs client agreement supplement, combined fees charged by Interactive Brokers and Zerohash cannot exceed 30% of staking rewards, leaving clients at least 70%; fees apply only when rewards are actually generated, as detailed by The Defiant. Staked ETH is held in an account in the customers name at Zerohash, not inside the regulated brokerage account, and crypto there is not covered by SIPC protections or traditional securities customer rules, according to Finance Magnates. Clients remain exposed to typical staking risks, including validator slashing, network delays on unstaking, and any operational issues at Zerohash, and reward rates are explicitly not guaranteed because they depend on Ethereum network conditions and validator performance.

3. Why It Matters For Ethereum And TradFi

Interactive Brokers reports hundreds of billions of dollars in client assets and millions of accounts, so adding ETH staking brings Ethereums proof-of-stake rewards into a mainstream brokerage environment, alongside stocks, options and futures, as highlighted by The Block. IBKR joins other large brokers and fintechs that offer staking, but with a structure that keeps crypto in a separate account and caps fees, signaling an attempt to balance yield demand with regulatory and risk considerations. If the rollout proves popular and uneventful, it could encourage IBKR and peers to add staking for more proof-of-stake assets and may draw greater regulatory attention to how retail staking is offered and disclosed in traditional brokerage channels.

Conclusion

Interactive Brokers move to add Ethereum staking gives its clients a new way to earn protocol rewards on ETH inside a familiar brokerage interface, while shifting custody and validator operations to Zerohash. The launch strengthens Ethereums integration into traditional finance but also highlights the need for clients to understand fee caps, lack of brokerage-style protections on staked assets, and typical staking risks as this model expands.
