Interactive Brokers launches ETH staking service

TLDR

Interactive Brokers now offers Ethereum (ETH) staking through partner Zerohash for eligible clients, bringing native network rewards into a mainstream brokerage platform.

1. Interactive Brokers lets eligible clients stake ETH via its Client Portal, with Zerohash running validators and rewards paid as additional staked ETH.
2. This moves Ethereum staking further into traditional finance, potentially increasing staked ETH while competing with crypto-native staking and liquid staking tokens.
3. Users should watch eligibility limits, fee levels, custody protections and whether the service expands to more assets or jurisdictions as regulators refine their stance on staking.

Deep Dive

1. How The Service Works

Interactive Brokers (IBKR) has launched cryptocurrency staking for eligible clients, starting with Ethereum (ETH) only, accessible through a new Staking Dashboard in its Client Portal, with infrastructure provider Zerohash handling the staking backend and validators. Multiple reports confirm that earned rewards are credited as additional staked ETH that compounds while the position remains staked, rather than as cash payouts.

Under IBKRs supplemental client agreement, the combined fees charged by Interactive Brokers and Zerohash are capped at 30 percent of staking rewards, meaning clients retain at least 70 percent of any rewards, and no fee applies if staking earns nothing, according to coverage of the fee terms. Assets are held in a client-named Zerohash account and are not covered by SIPC protections that apply to securities in the brokerage account, and unstaking can be subject to Ethereums network unbonding periods plus Zerohashs own waiting windows.

2. Why It Matters For Ethereum

IBKR reports hundreds of billions of dollars in client assets and millions of accounts, so adding Ethereum staking for eligible clients is another step in ETHs integration into large, regulated investment platforms. This joins moves by firms like BNY Mellon and other custodians pushing staking and digital asset services to institutional clients.

For Ethereum, easier access to staking through a major brokerage could marginally increase the share of ETH that is staked over time, especially among investors who prefer to keep everything inside a single brokerage portal. At the same time, IBKRs offering competes with direct staking and liquid staking tokens (LSTs), where users may find different tradeoffs on yield, liquidity, and smart contract risk.

3. Risks And What To Watch

Key risks include custody and regulatory treatment. Staked ETH sits in a Zerohash account outside the core brokerage protections, and clients bear losses from validator slashing, service disruptions or prolonged unbonding delays, as highlighted in detailed coverage of the agreement. Reward rates are not guaranteed, since they depend on Ethereum network conditions and validator performance, and fee caps still leave up to 30 percent of rewards going to providers.

Going forward, it is useful to watch whether IBKR adds staking for other proof-of-stake assets, how eligibility varies by country and account type, and whether regulators in major jurisdictions further clarify staking as a service. Competitive pressure from other brokers and exchanges could also push fees lower or expand choices between native staking, LSTs and broker-run programs.

Conclusion

Interactive Brokers Ethereum staking launch shows traditional brokerages deepening their crypto offerings by plugging directly into network reward mechanics rather than treating crypto only as a trading product. That integration could slowly increase staked ETH and broaden participation, but the useful edge for investors comes from understanding how fees, custody and eligibility differ from crypto-native options and monitoring how regulation and competition reshape staking-as-a-service over time.
