Interactive Brokers (IBKR) has added stablecoin funding, external wallet transfers and nine new digital assets to its platform, extending the crypto functionality available inside its multi-asset brokerage account. The launch comes as traditional brokers increasingly compete with crypto-native platforms on infrastructure as well as trading costs.The most notable addition is stablecoin withdrawals. Clients can now withdraw US dollars through automatic conversion into USDC, PYUSD and RLUSD, allowing transfers outside traditional banking hours, including weekends.Competing on Cost and InfrastructureInteractive Brokers is positioning the crypto expansion around cost, access and infrastructure.The first lever is pricing. The broker says crypto commissions start at 0.12% to 0.18%, with no added spreads or markups. That undercuts many crypto-first platforms and traditional rivals, where all-in trading costs can be materially higher.The second is funding. Stablecoin infrastructure allow clients to move capital outside normal banking hours, including weekends.The third is wallet interoperability. Clients can now move assets between IBKR and external custodial or non-custodial wallets, functionality that remains unavailable on some traditional brokerage platforms.The fourth is product breadth. Crypto now sits alongside stocks, options, futures and IBKR’s unified prediction market interface, which aggregates contracts from Kalshi, CME Group and ForecastEx.A Broader Infrastructure Build-OutThe expansion follows IBKR’s recent AI integrations with ChatGPT, Grok and Claude for research and trading workflows.The broker has also broadened its digital asset offering beyond Bitcoin and Ethereum by adding tokens including Pax Gold, Uniswap and Aave.“We believe digital assets should be integrated into a client’s broader financial experience, not treated separately,” said Milan Galik, CEO of Interactive Brokers.IBKR’s latest launch reflects growing competition around crypto functionality rather than crypto access alone.Brokers increasingly compete on features beyond basic crypto trading, including wallet connectivity, stablecoin funding and broader digital asset coverage.IBKR combines those capabilities with multi-asset access, regulated infrastructure and established clearing relationships. Stablecoin funding and wallet connectivity are becoming part of the standard feature set for brokers offering digital assets.This article was written by Tanya Chepkova at www.financemagnates.com.
