What Is an OFS IPO and Why Doesn’t the Company Get the Money?

Imagine your neighbour sells his flat in your housing society to a new buyer. The builder who constructed the building years ago does not receive a single rupee from that sale. Only your neighbour, the seller, gets the money. An OFS IPO, or Offer For Sale IPO, works on the very same principle when a company goes public.

This is not just a textbook example either. NSE, the National Stock Exchange, opened its own Rs 22,561.57 crore initial public offering for subscription on 17-Sep-2026, closing on 21-Sep-2026. The entire issue is an OFS of 12.64 crore shares, and it was carrying an 11 percent grey market premium ahead of listing.

What Is an OFS IPO and How Is It Different From a Regular IPO?

An OFS IPO is a public share sale in which existing shareholders, such as promoters, private equity investors or the government, sell part of their own holding to public investors. No new shares are created. The company itself does not raise any capital in this process, and its bank balance stays exactly where it was before the IPO.

Think of a kirana store owner who decides to sell part of his personal ownership in the shop to a family member for cash. The store’s shelves do not get restocked with that money, and the till stays exactly where it was. Only the owner’s pocket changes. A fresh issue IPO is the opposite: the company itself borrows new share capital from investors specifically to fund its own business.

Why Doesn’t Money From an OFS IPO Go to the Company?

The money does not go to the company because, in an OFS, the shares being sold already exist and are owned by someone else, not the company. The seller could be a founder, a private equity fund, or, as with NSE, its own existing shareholders looking to monetise part of their stake. Buyers in the IPO pay that seller directly, through the stock exchange settlement system.

In fact, an OFS increases what is called the public float, the portion of shares available for ordinary investors to trade, without diluting existing shareholders further or adding any fresh debt or equity to the company’s books. Clearly, that makes an OFS a popular route for promoters or the government to trim their holding while meeting SEBI’s minimum public shareholding rules.

How Did NSE’s Rs 22,561.57 Crore OFS IPO Explain This in Practice?

NSE’s Rs 22,561.57 crore issue, which opened on 17-Sep-2026 and closed on 21-Sep-2026, was entirely an Offer For Sale of 12.64 crore shares. Every rupee paid by applicants in that IPO went to the existing shareholders who tendered those shares, not into NSE’s own treasury. The 11 percent grey market premium quoted ahead of listing signalled that investors expected the stock to list above its issue price. That premium, too, has nothing to do with money reaching NSE itself.

Interestingly, this pattern is common for large, well-established exchanges and financial institutions going public. They may not need fresh capital for expansion at that stage, but their existing shareholders want an exit route or partial liquidity. Having said that, investors should judge an OFS IPO on the company’s existing financials and growth prospects, exactly as they would any other listing, since the business is not receiving a capital injection to fund that growth.

The table below sums up the core differences between the two routes. The rupee figures in the last row are hypothetical, used only to illustrate the mechanics, and are not tied to any specific company or live IPO.

Basis	OFS IPO	Fresh Issue IPO
Who receives the sale proceeds	Existing shareholders	The company itself
Effect on total shares outstanding	Unchanged	Increases
Money available for the company’s growth plans	None	Full issue amount, minus expenses
Hypothetical Rs 500 crore issue (illustration only)	Rs 500 crore goes to selling shareholders	Rs 500 crore goes into the company’s bank account

Should You Invest in an OFS IPO?

Yes, you can invest in an OFS IPO the same way you would in any other IPO, but the decision should rest on the company’s business quality, valuation and growth outlook, not on where the money is headed. Since the company gets no fresh capital from an OFS, ask what its existing profits and cash flow already support, rather than assuming this IPO will fund a big expansion.

No wonder many first-time investors get confused, since news headlines rarely explain this difference clearly. If you are unsure how to deploy any listing gains you may earn from an IPO, a lumpsum calculator can show how a one-time amount could grow if reinvested, while a SIP calculator shows the effect of investing that same amount gradually instead. Some investors prefer to keep a portion of their money safe rather than chasing every new listing; an FD calculator can show what a fixed deposit would return over the same period, purely for comparison.

Frequently Asked Questions About OFS IPOs

Does an OFS IPO dilute existing shareholders? No. Since no new shares are created, an OFS does not dilute ownership the way a fresh issue does. It only changes who holds the shares that already exist.

Is an OFS IPO riskier than a fresh issue IPO? Not automatically. Risk depends mainly on the company’s fundamentals and valuation, not on whether the issue is structured as OFS or fresh issue.

Can a single IPO have both OFS and fresh issue components? Yes, many IPOs combine both, selling some existing shares while also issuing new ones to raise fresh capital for the company.

Why did NSE choose a pure OFS structure for its Rs 22,561.57 crore IPO? NSE’s issue of 12.64 crore shares was structured entirely as an OFS because its existing shareholders wanted to sell part of their stake. The exchange itself did not need fresh capital at this stage.

Does the grey market premium affect how much the company raises in an OFS IPO? No. The grey market premium reflects investor demand ahead of listing, but since the company does not receive any proceeds in an OFS, this premium has no bearing on its finances.

To sum up, an OFS IPO changes who owns a company’s shares, not how much cash sits in its bank account. Hence, the next time you see a large IPO number in the news, check whether it is an OFS, a fresh issue, or a mix of both, so you know exactly where that money is actually heading.
