BlackRock (BLK) — threat to the moat
The switching cost that traps the client traps BlackRock too: every release must keep giving yesterday's answer.
The switching cost that keeps clients in place applies to BlackRock as well. A platform embedded in hundreds of institutions' daily operations cannot be rewritten. Every change has to be backward compatible with every client's configuration, every model has to keep producing the answer it produced yesterday, and every release has to be validated by clients whose regulators expect them to demonstrate they understand what changed.
That is the correct way to run critical infrastructure, and it is a genuine competitive vulnerability against a newer entrant with no installed base to protect. The challenger can adopt a new data architecture, a new analytics approach or a new interface wholesale. Aladdin can adopt it for new clients and must keep supporting the old way for everyone else.
The place this bites is at the frontier. When a new asset class or a new modelling technique becomes important, the specialist vendor built around it will be better at it than the general platform, and the general platform's answer is to acquire — which BlackRock has done repeatedly, buying eFront for private markets workflow and Preqin for private markets data1.
That strategy works and it is not free. Each acquisition adds an integration obligation and a second set of conventions to reconcile, which is the same problem the platform exists to solve. Watch whether technology revenue growth excluding acquisitions holds up: 16% in 2025 stripping out Preqin2 is the honest organic figure, and it is the one that tests whether the platform is still winning on its own merits.
