How it makes money

Most of the money is a commission on trades executed on the platforms. Commissions come in two forms: variable transaction fees, charged per trade and usually scaled to the size and maturity of the bond, and fixed distribution fees, a subscription-style charge dealers pay for access to the platform. In 2025 variable transaction fees were $600.4 million and fixed distribution fees $134.2 million, out of $846.3 million of total revenue. The rest is recurring service revenue: information services (data and pricing subscriptions), post-trade services (regulatory reporting and trade matching) and technology services, together $111.6 million in 2025. So the top line tracks how much bond volume moves across the platforms, cushioned by a smaller subscription base.

Revenue by segment

The advantage is liquidity begetting liquidity: the more investors and dealers quote on Open Trading, the better the prices, and better prices attract more participants — a pool of roughly 1,800 active firms that a new entrant cannot simply buy. Years of executed trades also feed the CP+ pricing data that the company then sells back to the market, which is an intangible a smaller rival cannot replicate. The reason for calling it narrow rather than wide is that the company's own filing stresses substantial competition and a rapidly evolving industry, and that clients can and do route the same order flow to competing venues; the network is real but it has not prevented rivals from taking share in electronic credit trading.

Revenue follows the volume of bonds changing hands, and that volume has two opposing drivers over a cycle. Bond issuance and portfolio rebalancing fall when credit markets freeze, which hurts; but volatility and repricing episodes push more investors to trade and to seek the platform's all-to-all liquidity, which helps. Electronic adoption in fixed income is also still growing structurally, a tailwind that runs underneath the cycle. The subscription lines — data, post-trade reporting, technology, together about one euro in eight — are steadier than commissions. The result is a business that is less cyclical than an investment bank but clearly exposed to how active credit markets are, and to how much of that activity lands on its own venues rather than a competitor's.

Key risks

• Demand depends on factors outside the company's control — The filing states that global economic, political and market factors beyond its control — interest rate movements, inflation, geopolitical tension — could reduce demand for its services, and that a decline in fixed-income trading volumes would harm its business and profitability.
• Substantial competition — The company discloses that it faces substantial competition that could reduce trading on its platforms or its market share and harm its financial performance.
• A rapidly evolving industry — The filing warns that the industry is evolving quickly and that, if the company cannot adapt effectively to keep pace, it may not compete effectively — with a material adverse effect on its business, financial condition and results.
• Dependence on broker-dealer clients — The company relies on broker-dealer clients to provide liquidity on its platforms; the filing notes that these clients may reduce their activity or move it to competing venues, lowering volumes.
• Regulation, and self-clearing — As a regulated financial intermediary the company is subject to extensive government oversight that can affect volumes and raise costs, including changes in data protection and AI rules; it also flags the operational, liquidity and regulatory demands of self-clearing and the effect of central clearing mandates for U.S. Treasury securities.
• Technology, cybersecurity and third-party suppliers — The business runs on its own systems and on third-party providers; the filing identifies information-technology and cybersecurity failures, and the failure of a supplier, as risks to operations, and adds that developing and deploying AI technology can expose it to reputational harm and liability.

The filing does not disclose a percentage of revenue from its largest clients. It does warn, as a risk factor, that certain clients may account for a significant portion of trading volume on its platforms, and the business depends on a relatively small group of broker-dealers to supply liquidity alongside a much broader base of institutional investors. Without a stated number, treat the concentration as acknowledged by the company but unquantified.
