Abigail Johnson

In a decade as Fidelity’s leader, Abigail Johnson has expanded her family-owned financial empire, pushing further into private markets and alternative investments like cryptocurrency. ­Fidelity’s $5.9 trillion in ­discretionary assets under management in 2024—a $1 trillion jump from 2023—puts it behind only BlackRock and Vanguard. Much of Fidelity’s success is owed to retail offerings like its brokerage, wealth advisory, and 401(k) services, business lines Johnson has nurtured.
