⚠ A Tipping Point Tips Both WaysModerate threat

BlackRock (BLK) — threat to the moat

An advantage built on the deepest pool moves in both directions: digital assets went from nothing to $78 billion in two years, then back to $48.8 billion in six months.

The trouble with an advantage built on being the deepest pool is that depth is a relative measure with a threshold, not a gradient.

A category won in two years lost 38% of its assets in six months, mostly on price rather than redemptions.

For as long as iShares Core is the most traded fund in its category, the institutional flow arrives by default and the advantage self-reinforces. But nothing about the mechanism guarantees BlackRock is the one on the right side of it. In any category where a rival crosses the liquidity threshold first — a new exposure, a new market, a new wrapper — the same physics that protect BlackRock's flagships work against it, and the assets do not trickle across, they move.

There is a live example in BlackRock's own numbers. Digital asset ETPs went from essentially nothing to $78 billion of assets1 in about two years, on $35 billion of 2025 inflows2, because BlackRock reached scale in a brand-new category before anyone else. That is the mechanism working in BlackRock's favour. It is also a demonstration that a $78 billion pool can be assembled from a standing start inside twenty-four months when the category is new. The same pool held $48.8 billion six months later, after $3.1 billion of net outflows in the June quarter3; depth measured in dollars moves with the asset, and the threshold with it.

What would falsify the argument on this page is a large, established iShares fund losing its liquidity leadership to a rival — not losing assets on fees, which happens routinely and matters little, but losing the tighter spread. Watch relative daily trading volumes in the flagship categories, not expense ratios.
