The world of institutional crypto trading just got a major new player. On September 13, 2021, Interactive Brokers Group — one of the largest electronic trading platforms globally — announced the launch of cryptocurrency trading services for its clients, marking a significant milestone in the ongoing integration of digital assets into traditional finance.
Through a partnership with Paxos Trust Company, Interactive Brokers now enables its clients to trade and custody four of the most prominent cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), and Bitcoin Cash (BCH). The move brings crypto trading capabilities to a platform that serves over 1.5 million client accounts across more than 200 countries and territories.
TL;DR
- Interactive Brokers launches crypto trading on September 13, 2021
- Partnership with Paxos Trust Company for custody and execution
- Four cryptocurrencies supported at launch: BTC, ETH, LTC, BCH
- Bitcoin trading near $44,963, Ethereum around $3,200 at the time
- Major institutional broker bridging traditional finance and crypto
A Strategic Move Into Digital Assets
Interactive Brokers’ entry into cryptocurrency trading represents more than just another exchange listing — it signals a broader shift in how established financial institutions view digital assets. The Greenwich, Connecticut-based broker has long been known for providing access to stocks, options, futures, currencies, bonds, and funds across 150 markets in 33 countries. Adding cryptocurrencies to this roster demonstrates how digital assets have evolved from a niche curiosity to a mainstream asset class.
The choice of Paxos as a partner is notable. Paxos Trust Company is a regulated financial institution that holds both a New York State Department of Financial Services (NYDFS) trust charter and a New York banking license. By partnering with Paxos, Interactive Brokers can offer crypto trading within a regulated framework — an important consideration for institutional investors who require compliance-grade custody and execution services.
Market Context: A Turbulent September
The launch came during a turbulent period for crypto markets. Bitcoin was trading at approximately $44,963 on September 13, down 2.7% on the day and nearly 14.6% over the previous week, according to CoinMarketCap data. Ethereum hovered around $3,200, having dropped 4.7% in 24 hours. The broader market faced headwinds from multiple directions.
House Democrats had just outlined plans for a series of tax increases that included new regulations targeting cryptocurrency transactions. The regulatory uncertainty contributed to a sell-off that saw major tokens including Bitcoin, Ethereum, and Dogecoin post significant losses. Against this backdrop, Interactive Brokers’ decision to launch crypto services was particularly bold — signaling confidence in the long-term trajectory of digital assets despite short-term volatility.
The Institutional Wave Continues
Interactive Brokers was not the only major financial institution making crypto moves that week. Fidelity Investments, one of the world’s largest asset managers, was reportedly expanding its cryptocurrency team by 70% — a clear indication that traditional finance giants were betting heavily on the space. Mastercard had also announced its acquisition of CipherTrace, a blockchain analytics firm, underscoring the payment industry’s commitment to building crypto compliance infrastructure.
These developments collectively paint a picture of an industry that is rapidly maturing. From trading platforms to asset managers to payment networks, the infrastructure supporting institutional crypto adoption was being built at an accelerating pace in September 2021.
What This Means for Crypto Adoption
Interactive Brokers’ crypto launch matters because of who its clients are. Unlike retail-focused exchanges that cater primarily to individual investors, Interactive Brokers serves a significant base of financial advisors, hedge funds, and institutional traders. By offering crypto trading alongside traditional assets on a single platform, the broker is effectively removing one of the key barriers to institutional crypto adoption: the need to manage separate accounts across different platforms.
The integration also makes it easier for financial advisors to allocate a portion of client portfolios to cryptocurrencies — a prospect that was becoming increasingly attractive as Bitcoin cemented its position above $40,000 following a dramatic summer that saw prices swing from below $30,000 to above $50,000.
Why This Matters
When one of the world’s largest electronic brokers with over $300 billion in client equity decides to offer crypto trading, it is not a trial balloon — it is a strategic commitment. Interactive Brokers’ partnership with Paxos bridges the gap between traditional finance and digital assets in a way that prioritizes regulatory compliance and institutional-grade infrastructure. For the crypto industry, this represents another step toward mainstream acceptance and signals that the institutional adoption trend that began with Bitcoin ETF applications and corporate treasury allocations is now extending into the broker-dealer space.

paxos partnership was the safe play. NYDFS trust charter means IBKR didnt have to deal with any custody regulatory mess. smart move by Thomas Peterffy
only 4 coins at launch feels conservative but makes sense for an institutional platform. BTC ETH LTC BCH covers probably 80% of what their clients would ask for anyway
1.5 million accounts across 200 countries and they waited until 2021 to add crypto? fidelity was ahead of them on this one. still bullish on what it means for adoption tho
