On 10 August, Nvidia signed memoranda of understanding with six financial firms to build platforms capable of mobilizing more than $500bn of third-party capital for AI computing infrastructure. The signatories were Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR. The structure exists so that data centers, power and land get funded without adding to Nvidia's own balance sheet, with Goldman — the only bank in the group — expected to lead the associated public debt sales.

The next session, the eleven firms examined here rose 4.2% on average, their best day of the summer. That is most of the story of their month. Three other broad sessions — 28 July, 3 August and 13 August — carried nearly all the rest, and the remaining fifteen trading days averaged roughly flat. Remove each name's two best sessions from the 30 days to 14 August and eight of the eleven go negative: Goldman -16.1%, Morgan Stanley -10.5%, Brookfield Corporation -6.6%, Carlyle -5.6%, Brookfield Infrastructure -4.4%, KKR -2.0%, Blackstone -1.9%, Ares -0.3%. Only Apollo and Brookfield Asset Management stay up. None of the four big sessions was an earnings date for anyone in the group.

Two entirely different years

The twelve-month picture is not flat, it is bimodal. The firms that manage other people's money were mauled: Ares -24.4%, Carlyle -24.1%, KKR -21.9%, Blackstone -17.6%, Brookfield Asset Management -12.6%. The firms that underwrite the debt or own the assets had a fine year: HA Sustainable Infrastructure +57.9%, Morgan Stanley +46.4%, Goldman +39.1%, Brookfield Infrastructure +33.1%. The damage to the first group traces to March 2026, when redemption requests at retail-facing private-credit vehicles turned into a sector-wide panic. Requests at the twelve largest non-traded business development companies averaged 12.1% in the first quarter, well above the 5% level at which managers gate — while non-accruals in those same portfolios ran at 0.6%.

The fee engines accelerated

Blackstone, which invests across real estate, credit, private equity and infrastructure, reported second-quarter fee-related earnings of $1.8bn, up 22%, on record assets under management of $1.35 trillion. Its data-center platform is now worth $185bn, against $130bn in January, and nine of its ten largest quarterly markups were AI-related. Reported revenue rose 28.5% with operating margin at 61.9%, from 51.6% a year earlier.

Apollo, which pairs an origination machine with the Athene retirement balance sheet, produced record fee-related earnings of $785m, up 25%, with fee-generating assets up 34%. It originated $74bn in the quarter, before counting the $35bn facility for Broadcom that it calls the largest private-credit financing ever written. Three-quarters of what it originates is investment grade.

KKR posted record fee-related earnings of $1.32 a share, up 34%, and holds $72bn of committed capital not yet earning fees — an embedded tailwind at roughly 90 basis points. In June it launched Helix, a permanent vehicle with more than $10bn of founding capital from KKR, the Kuwait Investment Authority, Nvidia and Vistra, run by former Amazon Web Services chief Adam Selipsky as a single counterparty for hyperscalers.

Ares, the most credit-heavy of the group, grew fee-related earnings 20% to $491m at a 42.3% margin and raised a record $36bn in the quarter. Its Ada platform is building seven data-center campuses totaling about one gigawatt. Crucially for the March narrative, its non-traded BDC redemption queue fell from about $1.2bn to $600m and non-accruals there sit at 0.5%.

Brookfield Asset Management grew fee-related earnings 20% to $808m and raised $77bn in a single quarter, its best ever. It runs about $85bn of digital infrastructure, launched a $10bn AI fund against a pipeline above $100bn, and says every AI deal is contracted to a named counterparty with no speculative construction. It bought back $575m of its own stock this year on the view that the shares are cheap.

Carlyle, which runs buyouts, credit and the AlpInvest fund-of-funds business, earned a record $472m of distributable earnings and $111m of capital-markets fees, more than double last year. It returned $37bn to investors over twelve months — evidence that exits are not shut.

The banks are the odder case

Goldman Sachs booked record second-quarter revenue of $20.3bn at a 23.5% return on equity, with advisory revenue up 17% and the deal backlog at a five-year high. It fell 9.8% over the month. Morgan Stanley reported record revenue of $21.3bn and investment banking up 58%, and passed Goldman into second place globally with $2.3bn of first-half capital-markets fees against $1.4bn a year earlier, almost all of the increase from AI infrastructure work. It fell 4.9%. The two cheapest names here — Goldman at 14.9x forward earnings against 15.8x trailing, Morgan Stanley at 16.9x against 17.5x — declined into a fee pool that is still growing. Data-center asset-backed issuance has gone from $4bn in 2020 to $61bn so far in 2026.

Among the asset owners, Brookfield Infrastructure — a partnership holding utilities, transport, pipelines and roughly 50 data centers — grew funds from operations 10% a unit, with its data segment up 36%. HA Sustainable Infrastructure, a 170-person specialty lender to renewable and efficiency projects, grew revenue 41% to $120.8m. Brookfield Corporation, the holding company whose main asset is 73% of Brookfield Asset Management, is the one name genuinely in a downtrend, its 50-day average below its 200-day since early August; its first-quarter revenue grew 2.5% and it netted $100.6m on $18.4bn of sales.

What the price already assumes

The managers rallied and remain 12% to 29% under their highs. Their forward multiples sit far below trailing ones — Carlyle 13.7x against 48.7x, Apollo 16.0x against 30.5x, KKR 18.4x against 33.9x, Blackstone 24.3x against 32.0x, Ares 24.5x against 62.9x. That gap is the market underwriting the fee build, not doubting it. Brookfield Asset Management is the exception at 29.5x forward against 31.2x trailing, with the least acceleration embedded.

The cautions come from the managers themselves. KKR said hyperscaler data-center spreads have widened lately and the market is showing indigestion on large deals. Blackstone guided third-quarter realizations to decelerate. Goldman said the build-out "won't be a straight line" and could see recalibrations within 6 to 18 months.

The setup

Where it stands — Fee earnings are compounding at 20%+ across the managers while their shares remain well below last year's highs. Would confirm — Third-quarter fee-related earnings growth holding above 20% at Blackstone, Apollo and Ares. Would invalidate — Direct-lending non-accruals rising above 2%, or BDC redemption queues re-widening toward first-quarter levels. Watch next — Third-quarter results in late October, and Blackstone's guided realization rebound in the fourth quarter. Valuation — Managers at 13.7x-24.5x forward against 30x-63x trailing; Goldman 14.9x forward versus 15.8x trailing.
