Its engineering contributions include MABWiser, a Python library developed by Fidelity’s Artificial Intelligence Center of Excellence for prototyping multi-armed bandit algorithms. It supports contextual models, parallel training and testing, and simulation for comparing policies; integration with Mab2Rec lets developers build content- and context-aware recommendation systems.

Fidelity combines investment products with infrastructure used by other financial firms. The company reported $19.9 trillion in assets under administration and $7.8 trillion in managed assets at the end of Q2 2026. Its distribution spans digital channels, telephone support, and Investor Centers, serving customers who want financial guidance as well as those making their own investment decisions.
