Jane Street reported a trading haul of $40 billion for the period referenced by sources, a figure disclosed in an Investing.com piece dated April 25, 2026. The claim, which sources told Investing.com placed Jane Street ahead of prominent market-making rivals, has prompted renewed scrutiny of the economics of principal trading firms and the distribution of liquidity across global venues (Investing.com, Apr 25, 2026). For institutional investors, the scale of the reported intake—if confirmed—would represent a material shift in the share of trading profits captured by privately held quantitative trading houses versus publicly listed broker-dealers. Jane Street, founded in 2000, operates as a private, technology-first market maker across equities, ETFs, options and fixed income, and the new figure has refocused debate on the degree to which market-making revenues are concentrated (Jane Street corporate materials). This piece analyses the data points available, places them in market context, examines sector implications and offers the Fazen Markets perspective on durability and regulatory collision risk.
The $40 billion figure was first reported by Investing.com on April 25, 2026 and attributed to people familiar with the firm’s business; Jane Street itself has not publicly released consolidated annual revenue figures because it is privately held (Investing.com, Apr 25, 2026). Market-making and proprietary trading firms operate with a different public profile from broker-dealers listed on exchanges, which can make direct apples-to-apples comparisons difficult. For example, listed counterpart Virtu Financial (VIRT) discloses annual net trading revenues in public filings, whereas Jane Street’s private structure means external observers must rely on vendor reports, industry tallies and regulatory filings that do not map perfectly to internal revenue concepts.
Historically, large principal trading firms have benefited from electronic market proliferation and fee and spread capture across equities and ETFs. Since the 2010s, structural changes—such as maker-taker pricing models, the growth of ETF trading and the fragmentation of order flow across lit and dark venues—have amplified opportunities for firms with low-latency execution and proprietary pricing algorithms. Jane Street’s reported haul coincides with a multi-year expansion in electronic ETF and options volumes; while the firm’s precise exposure mix is opaque, its public communications and job listings emphasize ETFs, options, and cross-asset electronic execution as core competencies (Jane Street website).
The scale implied by $40 billion also raises questions about operational footprint and risk management. A privately held, high-frequency-focused firm generating trading revenues at this level would necessarily operate significant market access, capital allocation and risk-monitoring infrastructure across multiple jurisdictions. That profile has consequences for counterparties and clearing intermediaries that absorb intraday and settlement exposures created by principal trading activity.
Primary data point: the $40 billion trading haul was reported on April 25, 2026 by Investing.com and attributed to sources briefed on the matter (Investing.com, Apr 25, 2026). Secondary corroboration is limited in the public domain because Jane Street does not file consolidated revenue reports with securities regulators. That means the $40 billion figure must be treated as a high-quality journalistic source-based claim rather than a certified financial disclosure.
Comparative frame: listed market-makers and trading firms typically report annual revenues in published 10-Ks and earnings releases. Those public numbers for listed peers are generally in the low billions to single-digit billions range in recent years; by contrast, a $40 billion trading haul—if it reflects gross trading revenues—would sit well above publicly disclosed annual revenues of listed counterparts. The distinction between gross trading revenue (which can be large and include pass-through items) and net income or adjusted operating revenue is critical. Public companies present reconciled metrics that permit margin and profitability analysis; that transparency is absent for private houses.
Timing and scope: the Investing.com note does not specify whether the $40 billion represents calendar-year 2025 trading revenue, gross trading flows, or an alternative metric. Institutional readers must therefore parse three possibilities: 1) $40 billion as net trading revenue, 2) as gross trading proceeds that include client pass-throughs, or 3) as a multi-year or multi-product aggregate. Each interpretation implies very different market consequences. Absent an official company statement or regulatory filing, the conservative analytic stance is to treat the number as an industry-sourced estimate rather than a definitive audited figure.
A materially larger private market maker capturing a disproportionate share of trading revenue shifts competitive dynamics in several ways. First, counterparty pricing: exchanges, brokers and asset managers negotiating execution fees must account for the bargaining leverage of dominant liquidity providers. Second, liquidity concentration: a handful of technology-first firms taking outsized revenue shares can compress visible spreads on many instruments but may also raise systemic concentration risk if those firms withdraw from markets during stress.
Third, product focus: Jane Street’s public presence as an ETF and options liquidity provider suggests that growth in those segments contributed materially to the reported haul. ETF average daily volume has become a major profit center for top-tier market makers because ETFs require continuous quoting across thousands of listings and attract arbitrage activity. Firms that combine capital provision with sophisticated hedging technology can capture spreads and rebalance costs more efficiently than traditional dealers, tilting profitability.
Finally, the juxtaposition of private scale and public opacity may accelerate regulatory and market-structure conversations. Market regulators and exchanges increasingly monitor order-flow concentration, execution quality and systemic dependencies on large principal trading entities. A reported $40 billion trading haul brings that debate into sharper relief: policymakers may examine whether venue incentives, fee schedules and reporting regimes adequately surface risks associated with concentrated principal trading volumes.
The foremost risk in interpreting this report is measurement risk: the lack of an audited disclosure leaves open alternative readings of the $40 billion figure. Analysts must therefore avoid conflating the headline number with net profit or free-cash-flow metrics that matter for counterparty credit and systemic stress testing. Overstating the economic implications without precise metric definitions would mislead investors and counterparties.
Operational and market risk are second-order concerns. A firm handling large intraday flows must maintain robust clearing relationships and capital buffers; counterparty exposures to a dominant market-maker can magnify settlement and intraday liquidity risk if the firm curtails activity. Clearing houses and prime brokers may respond by tightening margin models or pricing intra-day access differently for off-exchange principal flow if concentration increases.
Regulatory risk is also non-trivial. If regulators determine that concentrated principal trading creates market fragility or harms execution quality, they could consider enhanced disclosure requirements, venue fees adjustments or targeted reporting on liquidity providers. Such interventions would alter the profit calculus for private trading firms and could compress margins or raise compliance costs.
Near term, the market will seek clarity. The investing community will watch for any official Jane Street statement, corroborating reports from Bloomberg/Reuters or regulatory filings that help define the $40 billion metric. In the absence of clarification, counterparties and prime brokers are likely to conduct internal stress and exposure reviews to reassess capital and settlement arrangements. Firms that rely on continuous principal liquidity provision may model scenarios where a top-tier market maker reduces posting activity for specific products.
Medium term, the dynamics that enabled a large private house to expand—proliferation of electronic trading, shift toward ETFs, and improvements in algorithmic hedging—are structural and likely durable. However, durability of outsized profits is contingent on regulatory stance, competitive entry (including from private equity-backed competitors), and potential margin compression from exchange fee changes or price competition.
For asset managers and institutional brokers, the pragmatic response is enhanced operational due diligence and scenario planning: measure execution quality across venues, stress-test reliance on specific liquidity providers, and monitor venue-level concentration metrics. Those steps will become standard enterprise risk management practices if an independent confirmation of the $40 billion figure emerges.
Fazen Markets views the report as a tipping-point signal about market concentration rather than an absolute statement of profitability. Even if the $40 billion headline overstates net returns and instead reflects gross trading volumes or pass-through activity, the strategic outcome is similar: private, technology-led firms have meaningfully scaled their footprint in global electronic markets. That scaling compresses visible spreads for institutional order flow while simultaneously concentrating execution risk in a smaller set of actors.
Contrary to the prevailing narrative that larger principal houses only reduce costs for end investors, there is a countervailing dynamic: outsized private profits can incentivize migration of order flow to opaque routing arrangements and bespoke agreements that reduce public transparency. In our view, the most consequential near-term outcome from a confirmed $40 billion figure would not be an immediate regulatory clampdown, but a gradual shift in execution governance at asset managers, who will demand more transparency on how their flow is priced and routed.
Fazen Markets recommends investors treat the report as a catalyst for renewed operational due diligence rather than as a valuation lever. Examination of execution quality, exposure concentrations and contingency plans for liquidity withdrawal should become routine.

Q: Does the $40 billion represent profit or revenue?
A: The Investing.com report does not specify whether $40 billion denotes net trading profits, gross trading revenues, or an aggregate of proprietary trading flows. Without an official company disclosure or audited statement, treating the figure as an industry-sourced estimate is prudent. Historically, gross trading volumes or revenue figures can be many multiples of net profit.
Q: What does this mean for public market-makers like Virtu (VIRT)?
A: Public peers disclose net trading revenues and margins in filings, which typically put them in the low to single-digit billions of revenue annually. A private firm reporting larger headline numbers increases competitive pressure on public market-makers but does not directly translate into share-price impact without corroborated profitability metrics. Market participants should watch for margin compression, pricing changes at venues, and any disclosures from listed peers.
The Investing.com report that Jane Street generated a $40 billion trading haul (Apr 25, 2026) is a material industry signal but lacks the granularity required to draw definitive conclusions about profitability or systemic risk. Institutional investors should prioritize operational due diligence, counterparty exposure reviews, and monitoring for regulatory responses.
