Stock brokers processed more than 21.3 crore transactions, with a combined value of ₹2.95 lakh crore. They represented roughly 92% of capital-market UPI transaction volume. The figures point to widespread use of UPI for adding money to trading accounts, rather than relying on channels such as net banking.

The validated framework includes the '@valid' handle, which helps secure payments by linking them to an investor’s verified bank account. Beyond brokerage funding, UPI is being used for share offers, mutual fund purchases and payments to investment professionals.

IPOs generated around 1.07 crore UPI transactions totalling ₹20,458 crore. Most used UPI ASBA, under which application funds remain blocked in the bank account rather than being transferred upfront. Kotak Mahindra Bank experts put this route’s share of retail IPO applications at 60–70% and said bank systems can process 5,000 transactions a second during major market events.

Mutual funds accounted for 70.36 lakh transactions worth ₹8,475 crore, while research analysts and investment advisers received more than ₹126 crore in fees through UPI. India had 22.5 crore demat accounts and 12.2 crore unique investors by March 2026, providing a sizeable base for digital investment payments.
