India’s largest lender State Bank of India (SBI) is set for a return of nearly 3,82,567% on its original investment, while Amundi India Holding stands to book a 13,095% gain, as the two promoter shareholders prepare to pocket a combined ₹11,658 crore in profit through SBI Funds Management's (SBI Mutual Fund) initial public offering, which is the biggest Indian IPO of 2026 so far.

SBI Funds Management Ltd, a subsidiary of State Bank of India, on Thursday announced a price band of Rs 545 to Rs 574 per share for its Rs 11,693 crore IPO. At the upper end of the band, SBI's stake, acquired at a weighted average cost of just 15 paise a share, will fetch gross proceeds of Rs 7,366.39 crore against a cost basis of roughly Rs 1.93 crore, translating into a profit of about Rs 7,364.47 crore.

Amundi, which paid a weighted average cost of Rs 4.35 a share, will generate gross proceeds of Rs 4,326.52 crore against a cost basis of Rs 32.79 crore, for a profit of approximately Rs 4,293.73 crore.

The much-awaited IPO is entirely an offer for sale (OFS) of more than 20 crore shares, with no fresh issue of equity, meaning SBI Funds Management itself will not receive any proceeds from the offering.

SBI plans to sell as many as 128.3 million SBI Funds shares, or about 6.3% of the company, while Amundi will offload 75.4 million shares, or about 3.7%. Combined, the two promoter-sellers are divesting just under 10% of SBI Funds Management's paid-up equity share capital through the offer.

At the top of the price band, SBI Funds Management is valued at nearly Rs 1.17 lakh crore in terms of market capitalisation. The IPO opens on July 14 and closes on July 16.
