Goldman Sachs, JPMorgan, Morgan Stanley dominate AI stock boom

Fueled by the worldwide increase in synthetic intelligence shares, relaxed capital guidelines and larger lending to hedge funds, huge Wall Road banks have already had a banner yr for equities buying and selling — even with one quarter left to go.

The 5 largest funding banks have generated about $67 billion in equities income by way of Sept. 30, in keeping with firm filings. That’s $7 billion greater than what the group made throughout all of 2025, which itself was a document haul.

Nevertheless it’s Wall Road’s Huge Three which have captured the most important slice of what’s shaping as much as be the business’s most profitable enviornment: Goldman Sachs, JPMorgan Chase and Morgan Stanley have made a mixed $52 billion in inventory buying and selling income thus far this yr, practically 80% of the full.

“In relation to the AI mega commerce, the Huge Three think about one another their fundamental opponents, and that is just about it,” Mike Mayo, Wells Fargo banking analyst, instructed CNBC. “They have been greatest positioned to benefit from this market.”

Wall Road banks are experiencing an epic run of blockbuster income as the full worth of the inventory market balloons and buying and selling exercise from institutional and retail traders rises throughout shares, exchange-traded funds and derivatives. Serving to drive this exercise are the loans that the banks, by way of their prime brokerages, are extending to hedge funds in order that they will amplify their bets.

Prime brokerage — the enterprise of offering hedge funds with margin loans, securities lending and different buying and selling companies — has develop into a key battleground and supply of development. The Huge Three’s prime brokers are central to the bigger equities story as a result of they serve the most important funds throughout markets and merchandise.

Demand for leverage to make bets on AI {hardware}, hyperscalers and chip suppliers has reached new heights, financial institution executives stated final week.

At Goldman Sachs, equities financing actions jumped 96% within the third quarter to a document $3.37 billion. JPMorgan and Morgan Stanley do not get away that determine, however stated they noticed the same dynamic.

“I like your ‘insatiable demand for capital’ level. That feels about proper,” JPMorgan CFO Jeremy Barnum stated on the financial institution’s third-quarter convention name, responding to analyst questions on financing calls for.

“On this second the place AI is such an awesome theme … there’s capital being tapped by way of all types of various mechanisms,” Barnum stated.

That demand has helped rework fairness desks on the Huge Three from cyclical, transactional companies into extra sturdy, high-margin lending engines, Wall Road executives say.

The efficiency hole between Wall Road’s giants and rivals together with Financial institution of America and Citigroup highlights a widening divide in capital markets.

“For shoppers, the worth is not only a value on one commerce, it is protection and continuity,” Rachid Alaoui, JPMorgan international head of equities, instructed CNBC in an interview. “You need a supplier that may provide the full suite throughout merchandise, and also you need that service to journey with you throughout areas. That issues in burdened markets and intervals of volatility.”

Executing multibillion-dollar bets, like leveraged swaps on unstable AI shares or sector ETFs, can require an infinite steadiness sheet. The largest banks can take up potential $100 million losses with out threatening their quarters, in keeping with buying and selling executives. Smaller or extra area of interest banks cannot underwrite single-trade dangers of that magnitude, forcing them to say no the enterprise or cede share.

U.S. prime brokers have additionally benefited from the retreat of European banks together with Credit score Suisse from the equities enterprise, stated Bloomberg Intelligence analyst Herman Chan.

“Prime is without doubt one of the final scale companies,” Chan stated. “When you have a powerful equities franchise, the hedge funds will wish to transact with you as a result of you may have a much bigger pool of buying and selling alternatives with counterparties.”

Whereas U.S. markets have been swept up in software program and cloud computing giants this yr, buying and selling executives say the fastest-growing frontier for equities was in Asia.

Institutional traders poured into South Korea and Taiwan, concentrating on the “picks and shovels” of the AI provide chain: the reminiscence chipmakers and semiconductor producers supporting information middle development, Alaoui stated.

For the Huge Three, with their footprints throughout Tokyo; Hong Kong; Seoul, South Korea; and Mumbai, India; the Asia commerce was a goldmine. Nevertheless, buying and selling executives level out that transaction taxes and stamp duties are included in top-line income, artificially inflating Asia prime totals.

There’s additionally no agreed-upon definition of what equities buying and selling income ought to embody, so some banks embody enterprise strains like clearing companies that others exclude from their inventory buying and selling totals, making apples-to-apples comparisons troublesome.

However that does not change the general momentum of the enterprise, boosted by a inventory rally that started in October 2022, weeks earlier than OpenAI launched ChatGPT.

“We’re nonetheless in a stock-based world,” Morgan Stanley CEO Ted Choose stated on the agency’s earnings name. “Equities are nonetheless, all issues being equal, the enticing asset class.”

Whereas the CEOs of Goldman Sachs and Morgan Stanley have stated the AI build-out remains to be in its early years, if AI seems to be not as transformative as hoped, a downturn may impression these banks greater than others, analysts stated.

The increase has additionally drawn some concern over the attainable dangers posed by hedge funds.

The Worldwide Financial Fund warned this month that rising leverage, crowded positions and correlated promoting from hedge funds may create potential stability dangers. The IMF estimated that international hedge fund property had reached $13 trillion.

In August, JPMorgan CEO Jamie Dimon stated industrywide leverage was “the best it is ever been,” although he stopped wanting calling the chance sufficiently big to pose a risk to the monetary markets.

Wall Road executives and analysts identified that the business wasn’t fazed by the meltdown of a number of hedge funds this summer time. Whereas the hedge fund run by former OpenAI researcher Leopold Aschenbrenner, Situational Consciousness, garnered essentially the most headlines, a number of smaller corporations additionally skilled a compelled unwinding.

Prime brokers have discovered to leap on margin calls and rapidly take down threat when markets transfer in opposition to shoppers, JPMorgan’s Alaoui stated.

“In the summertime, some traders had positions they have been compelled to unwind,” he instructed CNBC. “They deleveraged, threat got here down, and the market moved on.”

One other issue driving the equities increase: Trump administration regulators have eased some leverage guidelines for the most important U.S. banks, giving them extra room to broaden steadiness sheet-heavy companies together with prime brokerage. The revised guidelines have been finalized in 2025, and banks have been allowed to undertake them as early as January.

By easing the stringent steadiness sheet caps that beforehand handled Treasurys and prime brokerage loans, that are collateralized, the identical as riskier property, regulators gave sellers larger flexibility to deploy steadiness sheet capital.

“Capital did go down, so it’s important to say the system is considerably extra levered due to the relief in laws,” stated Darrell Duffie, a finance professor at Stanford College and a number one skilled on monetary stability. “It isn’t a good suggestion, but it surely hasn’t gotten dramatically out of whack.”

The bigger measurement of the market and better volatility can create extra buying and selling, derivatives exercise and leverage, he stated, however that is not inherently alarming.

Wall Road executives additionally downplayed issues over leverage, declaring that they use collateral and frequent stress testing to get forward of issues.

“Hedge fund leverage as a contributor of threat to the system could be very a lot within the class of identified unknowns,” JPMorgan’s Barnum stated final week. “It doesn’t suggest it is riskless, however we form of know what it’s.”
