Alternatives: Three Percent That Pays FifteenNarrow moat

BlackRock (BLK) — moat facet

A six-to-one ratio is the entire explanation for $30 billion of acquisitions.

Alternatives ended 2025 at $424 billion — 3% of long-term assets1 — and produced 17% of long-term base fees2. Fixed income is 25% of the assets and 22% of the fees; equity is 61% and 50%3. Alternatives is the only category in the table that earns several times its weight.

The fastest-growing category is also the best paid, which is why $30 billion of equity went into buying more of it.

That ratio, six to one, is the entire argument for what BlackRock has been doing with its balance sheet. Global Infrastructure Partners brought $70 billion of client assets in October 2024. HPS Investment Partners brought about $118 billion in July 2025. ElmTree added $3 billion in September4. The five-year growth rate in alternatives is 22% a year, against 10% for the firm overall5.

Private markets also carry performance fees, which BlackRock's traditional business barely does. Private markets performance fees went from $308 million in 2024 to $695 million in 20256, and the total performance fee line rose from $1,207 million to $1,424 million7. That is a second income stream, uncorrelated with the fee rate on index products, that essentially did not exist at this scale three years ago.

There is a further reservoir the assets figure excludes: roughly $91 billion of unfunded, uninvested commitments, on which BlackRock earns nothing yet and will earn full fees when the money is called8. That is future revenue already contracted for, sitting outside every assets-under-management figure quoted anywhere.

The qualification is the obvious one. This was bought, at a price, and the price is visible in a shareholders' equity base that grew 42% in two years9 while earnings fell. Whether it was bought well will not be knowable for several fund cycles.

Moat trajectory: Widening

GIP, HPS and ElmTree added roughly $190 billion of client assets in under a year, alternatives are compounding at 22% against 10% for the firm, and $91 billion of committed capital is waiting to be called at full rates.

The number that tests this moat

Alternatives five-year growth rate
22% a year, vs 10% firmwide

Alternatives ended 2025 at $424 billion. The gap between 22% and the firm's 10% is what the acquisitions bought; if it converges toward the firmwide rate, the mix argument stops working.

⚠ THREAT 01
Everyone Is Buying the Same Thing at the Same Time
The same conclusion drew the same capital, which raises what the franchises cost and lowers what they earn.
