The rapid proliferation of digital investment platforms has fundamentally transformed the landscape of personal finance, enabling young investors to participate in capital markets with unprecedented ease and affordability. This paper examines the relationship between digital investment platforms and wealth maximization through mutual funds among young investors in India, with a specific focus on investors aged 18–35. India's growing digitally-savvy youth population presents a compelling opportunity for inclusive financial market participation; however, behavioural biases, financial literacy deficits, and platform trust concerns continue to limit optimal investment outcomes. Drawing exclusively on secondary data sources including SEBI reports, AMFI data, academic literature, and national financial inclusion surveys, this study analyses platform adoption patterns, mutual fund investment behaviour, and wealth creation potential among young investors. The findings reveal that while digital platforms have significantly lowered entry barriers, sustained wealth maximization requires improved financial literacy, goal-based investment strategies, and stronger regulatory safeguards. The study recommends integrated policy interventions combining investor education, platform transparency, and fintech innovation to harness the full wealth-building potential of young India's investment capacity.
