How Prime Brokerage Leverage, the $55B EA Merger Arb, Figma’s 250% IPO Pop, and Morgan Stanley’s Closed Derivatives Gap Co-Created Both a Record Quarter and Hedge Fund Returns Ranging from 10% to 45% in 2025
Morgan Stanley’s $17.9 billion Q4 2025 was not an outlier. It was the inevitable output of a machine that hedge funds and banks have spent years constructing together — one where every fee line on a bank’s income statement is the cost-of-capital line on a fund’s trade sheet. Here is exactly how that machine worked, mechanism by mechanism.
The Numbers Wall Street Reports vs. the Numbers That Matter
On January 15, 2026, Morgan Stanley posted Q4 2025 results that beat every analyst estimate. EPS came in at $2.68 against a $2.41 consensus, with the bottom line up 21% year-over-year. Investment banking fees surged 47% to $2.41 billion; advisory fees soared 45%; fixed income underwriting jumped 93%; equity underwriting grew 9%. Equity trading revenues climbed 10% to $3.7 billion.
The consensus read is straightforward: strong macro, recovering M&A, hot IPO market. That read is incomplete. The analytically richer question is what had to happen inside the world’s trading rooms for those line items to print the way they did. The answer, on almost every revenue line, is hedge funds. Prime brokerage leverage, merger arbitrage spread capture, IPO allocation mechanics, and derivatives flow are the actual gears. Morgan Stanley’s income statement is what happens when all four run simultaneously at near-peak throughput.
Each mechanism is individually significant. Viewed together, they are a single closed system — and understanding that system requires working through each gear in sequence.
I. Prime Brokerage: Record Leverage, Record Fees
Prime brokerage converts hedge fund balance sheets into bank revenue. Every dollar of leverage a long/short fund deploys against an equity position lives on the prime desk’s book. The bank earns a financing spread on that position for as long as the fund holds it. When funds run larger gross books at higher leverage ratios, bank prime revenue rises in direct proportion — there is no ambiguity in the transmission mechanism.
In 2025, that leverage was at near-all-time highs. Data compiled by Goldman Sachs, JPMorgan, and Morgan Stanley showed that leverage used by traditional long/short equity hedge funds continued rising throughout the year, approaching records. The consequence was predictable.
Morgan Stanley CFO Sharon Yeshaya explained it directly on the Q4 2025 earnings call: “Prime brokerage revenues drove the fourth quarter’s results. Client balances continue to rise, supporting the outlook for financing revenues.” — Q4 2025 Earnings Call Transcript
She had said almost the same thing in Q3 2025, when equities revenues hit $4.1 billion: “Prime brokerage revenues drove results as average client balances and financing revenues reached new records.” The language was not incidental; it was the structural explanation for the number.
CEO Ted Pick framed the systemic link directly in Q3: “We’re at 6,700 S&P and index asset price highs around the world. If there is a deleveraging event or a recession scare and the markets are lower, well, by definition, the financing revenues will be lower. I mean, they are linked in that sense, as you know, inextricably.” — Q3 2025 Earnings Call Transcript
The environment that enabled that leverage is the key variable. JPMorgan’s head of global equities, Rachid Alaoui, described it precisely in a Reuters interview: “We had a favorable trading environment, with a lot of rotation and trading activity but without extreme volatility. That allowed clients to add some leverage in prime without any credit or counterparty issues.” No counterparty stress meant no forced deleveraging. Funds held elevated gross exposure through the full year, compounding both their own returns and banks’ financing revenues.
The industry-level numbers frame the scale. Coalition Greenwich projects prime brokerage revenues at a record $32.7 billion in 2025 among top-tier prime brokers, an 18% increase over the prior year — consistent with a broader Finadium estimate of $37 billion when mid-tier providers are included, also up 18% and 23% higher than prior estimates focused only on top prime brokers. Both measures point to the same structural conclusion: a new high-water mark, whichever scope you apply. All of this sits within a total equities trading revenue pool projected at $94 billion — a 17% increase from 2024, surpassing the previous record of $85 billion set in 2007. Mollie Devine, head of markets competitor analytics at Coalition Greenwich, put it in one line: “Everything worked in equities this year: there were substantial upticks in cash, in derivatives, in prime.” — IFR
Cross-bank confirmation came from the same earnings cycle. JPMorgan reported a 40% surge in equities revenues to $2.9 billion, driven by prime; Bank of America saw a 23% jump in Q4 equities revenues; Citigroup reported prime balances up more than 50% year-over-year. Goldman CFO Denis Coleman explained why the business is structurally valuable, not merely cyclical, on Goldman’s Q3 2025 earnings call: “Balances are very, very correlated with overall levels in the markets. That is an attractive feature of the business. It has been, together with FICC financing, a good source of stable revenues for us across the franchise.”
Morgan Stanley specifically increased its share of the equities trading revenue pool by approximately 170 basis points over the trailing twelve months — a standout run, per IFR and Coalition Greenwich, that positioned it among the very top equities franchises globally.
That prime brokerage leadership had a structural ceiling, however — one that the firm had been quietly dismantling for two years. The ceiling was the derivatives gap.
II. The Derivatives Gap Closes — Yeshaya’s Most Important Disclosure
The single most analytically significant statement in Morgan Stanley’s Q4 call was buried in a competitive positioning answer. CFO Yeshaya told analysts:
“The growth of the derivatives business — a relative weakness of Morgan Stanley relative to the top-tier competitors — a lot of that has now been erased. So we actually are coming across now as a derivatives house as well for clients.” — Q4 2025 Earnings Call Transcript
The size of the prize that statement describes: global equity derivatives revenues across banks rose 19% in 2025 to $34.7 billion, a record, driven by single-stock volatility around technology names that facilitated substantial client flow across every desk. Every basis point of that market Morgan Stanley had previously ceded to Goldman or JPMorgan was a revenue gap. Closing it means internalizing that flow rather than watching it route elsewhere.
This was the payoff of a multi-year strategic campaign. CEO Pick had described the objective in Q2 2025 using the “old nine boxes” framework — prime brokerage, derivatives, and cash across three regions — noting that Morgan Stanley had been closing gaps with Goldman and JPMorgan across all nine simultaneously. By Q3, he was direct: “The development of our derivatives business, liquid derivatives and the cash business — once thought to be one that would be totally subordinate to prime — is now thriving.”
Why does this matter for hedge funds specifically? Derivatives are the primary instrument through which event-driven and macro funds express leveraged, asymmetric views: options on M&A target stocks, convertible bonds as pre-IPO expression vehicles, variance swaps as dispersion plays on earnings events. When Morgan Stanley closes the derivatives gap, flow that previously routed to Goldman or JPMorgan — and the bid-ask spreads and structured product margins on every trade — increasingly stays at Morgan Stanley. Every bookrunner mandate, every arb desk relationship, every prime client is now also a potential derivatives counterparty for the same bank that runs their book.
Those derivatives clients are not abstract. The single largest generator of hedge fund derivatives flow in 2025 was merger arbitrage — and the deal environment that year was extraordinary by any historical measure.
III. Merger Arbitrage: The Trade Anatomy Behind the 47% IB Fee Surge
Morgan Stanley’s 47% investment banking fee surge was manufactured by a specific deal environment — and that same environment handed event-driven funds their best systematic setup in years.
The professional framework was documented by Scott Schefrin, Portfolio Manager of AllianceBernstein’s Systematic Merger Arbitrage strategy. Schefrin has run risk arb books since 1993 and was previously global head of risk arbitrage, event-driven, and capital structure arbitrage at Bear Stearns, managing a $2.5 billion proprietary portfolio with over 35 professionals. In a December 2025 publication, Schefrin set out the year’s three-part structure:
First, a more predictable regulatory backdrop led to stronger deal flow, faster completions, and fewer deal breaks — the primary risk merger arbitrageurs underwrite. Compared to the long-run average, remarkably few deals collapsed, reducing what is often a sizable drag on merger-arbitrage performance. Second, the April tariff-driven equity sell-off created a buying opportunity for arb investors who rode a second wave of spread-tightening into July. Third, deal volume itself exploded: by Q3 2025, the number of US deals worth more than $5 billion had risen approximately 166% compared to the same period in 2024. The HFRI Event Driven Merger Arbitrage Index was up 8.2% through Q3 — the strongest first three quarters since 2021 and the second-best since 2009.
The Electronic Arts deal — the textbook case. On September 29, 2025, Electronic Arts announced it would be acquired by a consortium led by Saudi Arabia’s Public Investment Fund, Silver Lake, and Affinity Partners for $55 billion — the largest take-private transaction in history. EA stockholders would receive $210 per share in cash, a 25% premium to EA’s unaffected share price of $168.32 at market close on September 25. The transaction was funded by $36 billion in equity from the consortium and $20 billion of debt financing fully committed by JPMorgan Chase Bank.
The arb mechanics were structurally optimal. This was a pure all-cash offer — no stock-for-stock basis risk, no exchange ratio to hedge. Arbitrageurs simply bought EA shares below $210 and collected carry until close. JPMorgan’s committed debt financing eliminated financing conditionality risk — one of the two primary risks arb funds underwrite. The $1 billion termination fee payable by the consortium on a regulatory or deal failure gave arb books a contractual floor on downside. EA shareholders voted to approve the deal in December 2025, with close expected in Q1 FY27, keeping arb capital deployed and earning carry through the completion cycle.
Morgan Stanley did not advise on the EA deal — Goldman Sachs was EA’s banker. But that distinction is structurally irrelevant to the thesis. The explosion of the deal environment that generated the EA trade, the Union Pacific–Norfolk Southern merger (cited by AllianceBernstein as the largest M&A deal in five years), and the 166% surge in $5 billion-plus US deals is precisely what drove Morgan Stanley’s 47% IB fee increase and 45% advisory fee surge. The same regulatory environment and deal wave that gave arb funds their best setup in years gave Morgan Stanley its best banking year in years. They are fed by the same source.
Schefrin noted in the 2026 outlook that headwinds may emerge from spread compression as more arbitrage capital is deployed to exploit the favorable environment — itself a confirmation that returns were high enough to attract substantial new inflows. That capital is now looking for the next allocation vehicle. In 2025, one of the most crowded ones was the IPO queue.

IV. IPO Allocations: The Mechanism Finance Doesn’t Discuss Publicly
The same deal-origination machine that drove the 47% IB fee surge also determined who captured the first-day gain on every IPO the bank ran as joint bookrunner. Every bookrunner mandate is simultaneously a revenue event for the bank and an allocation decision for the funds inside its prime brokerage network. These are not independent variables.
Research published in the Journal of Portfolio Management documents the pattern precisely: investment banks that have prime brokerage relationships with hedge funds tend to allocate more IPO shares to those funds when serving as lead underwriters. The logic is transactional. Prime brokerage clients generate recurring, high-margin fee income for the bank. Bookrunners direct allocations toward the clients that maximize the total relationship economics, not just the IPO economics.
The Figma IPO on July 31, 2025, was the most extreme materialization of this dynamic in the cycle. Morgan Stanley, Goldman Sachs, JPMorgan, and Allen & Company were joint lead bookrunners. The offering was approaching 40 times oversubscribed. Figma’s stock surged approximately 250% on its first trading day, closing at $115.50 from an IPO price of $33 — one of the largest single-day IPO pops in decades. Analysis estimated that the company left more than $3 billion of primary proceeds on the table, with that value gap captured immediately by allocated institutional investors.
The mechanism that transfers that value is IPO allocation — which flows preferentially toward the same hedge funds paying prime brokerage fees to the banks running the book. The bank captures underwriting fees, advisory fees, and prime revenues on the same client relationship. The fund captures the IPO pop. CFO Yeshaya noted in the Q4 call that equity underwriting results were driven by convertibles and IPOs, contributing to 9% year-over-year growth in equity underwriting income. Each of those bookrunner mandates is simultaneously a fee event for the bank and an allocation event for its prime network.
This bundling — prime financing, M&A advisory, IPO bookrunning, and derivatives desk all serving the same institutional client — is not accidental. It is the architecture that CEO Ted Pick has spent two years deliberately constructing.
V. The Integrated Investment Bank: How Morgan Stanley Built the Loop
CEO Ted Pick and head of Institutional Securities Dan Nassetta have spent two years constructing what Morgan Stanley calls the “Integrated Investment Bank” — explicitly designed to maximize wallet share by bundling M&A advisory, derivatives, prime brokerage, and fixed income financing into a single institutional relationship. The thesis: a hedge fund that brings all its business to Morgan Stanley generates more total fee revenue per dollar of balance sheet than four separate relationships at four separate banks.
On the Q4 call, Pick described the capital deployment framework: “M&A acquisition financing, prime brokerage, fixed income secured lending, and other durable businesses that accrete to the broader integrated firm.” On the IPO pipeline: “We have very large private companies that are wildly successful that are probably going to start bridging to going public.” — Q4 2025 Earnings Call Transcript
The efficiency metric that validates the model: revenue growth in Institutional Securities was running approximately two times SLR and RWA growth since 2023 — demonstrating capital-efficient wallet share expansion. More fees per dollar of regulatory capital deployed is the signature of the integrated bundle working. The firm gained 100 basis points of wallet share with clients across investment banking and markets in 2025, confirming that clients are concentrating their flow — and their fees — at Morgan Stanley rather than spreading it.
The funds concentrating that flow are not abstractions. They are named institutions — and in 2025, their returns reflected precisely the machine this article has been describing.
VI. Hedge Fund Returns 2025: The Scoreboard
The funds on the other side of these transactions had their strongest year since the post-pandemic boom. D.E. Shaw’s Oculus Fund returned 28.2% net for 2025; its flagship Composite Fund returned 18.5%. Bridgewater’s Pure Alpha surged 34%, marking the firm’s highest profits in its 50-year history. Balyasny delivered 16.7%; Point72 returned 17.5%; AQR’s Apex Strategy gained 19.6%; ExodusPoint returned 18%, its best year on record; Millennium gained 10.5%; Citadel’s Wellington posted 10.2%. Michel Massoud’s event-driven Melqart Opportunities Fund surged 45%.
The breadth of strong performance across strategies — multi-strat, macro, event-driven, and quant — is the tell. This was not alpha generated in one pocket by one approach. It was a macro environment that simultaneously rewarded leverage (low volatility, rising markets), event positioning (record deal flow, few breaks), and IPO allocation (massive first-day pops). According to Goldman Sachs’ prime brokerage unit, stock-picking funds posted returns of 16.24% in 2025, roughly matching the S&P 500’s 16.4% — but at fundamentally different leverage profiles, amplifying nominal dollar returns on a larger gross book.
Vanessa Bogaardt, global head of capital introduction and prime financing at Bank of America, framed the year from the prime desk’s vantage point: “Overall, it has been a strong year for hedge funds across strategies, with decent alpha generation and recognition from allocators.” — Reuters
The returns range — 10.2% at the lower end to 45% at the top — maps almost exactly onto the degree of engagement each fund had with the mechanisms this article has described. Melqart’s 45% came from concentrated event-driven positioning in the same deal environment that gave Morgan Stanley its 47% IB fee surge. The multi-strats at 10%–17% were the large-book, high-leverage prime brokerage clients generating the financing revenues that drove every prime desk’s record year. The machine’s output on both sides of the ledger is consistent, coherent, and not coincidental.
The Closed Loop
Viewed individually, each mechanism — prime brokerage leverage, merger arb spread capture, IPO allocations, derivatives flow, the integrated client bundle — looks like a separate strategy or a separate business line. Viewed together, they form a single closed system with Morgan Stanley at the center, operating the same logic at every node.
Morgan Stanley originates M&A deals and earns advisory fees. Hedge funds run arb books on those deals using leverage financed by Morgan Stanley’s prime desk. Morgan Stanley serves as joint bookrunner on IPOs and allocates stock to its prime clients. Hedge funds trade derivatives on all of those equity events through Morgan Stanley’s desks. And because Morgan Stanley has now closed the derivatives gap with Goldman and JPMorgan — per Yeshaya’s own disclosure — the flow that once leaked to competitors increasingly routes back home.
This is the machine the opening described: every fee line on Morgan Stanley’s income statement is the cost-of-capital line on a fund’s trade sheet. That is not a metaphor. The prime desk charges the spread that the arb fund pays to lever its EA position. The IPO desk earns the underwriting fee that the allocated hedge fund offsets against its first-day pop. The derivatives desk captures the margin on the variance swap that the macro fund uses to express its view. The same dollar that moves through a fund’s P&L as a return moves through the bank’s P&L as a fee. They are the same transaction, told from opposite ends of the same ledger — and in 2025, both sides printed records simultaneously.
The question for 2026 is how much of that is cycle and how much is structure. The integrated investment bank model, the derivatives build-out, the prime brokerage market share gains — those are structural. The regulatory tailwind that drove the 166% surge in large M&A deals, the low-volatility environment that let funds hold peak leverage without forced deleveraging — those are cyclical. The machine will keep running. The only variable left to solve for is what fuel the environment provides — and that question, unlike the machine itself, is genuinely open.
