Anchor Investors and the QIB Book in an Indian IPO

The day before a main board IPO opens, the market watches one announcement closely: the anchor allocation. Who took the anchor book, at what price and in what size is read as a signal of institutional conviction. For the issuer, the anchor and QIB books are where much of the pricing work happens.

This note explains, from the issuer's side, who qualifies as a qualified institutional buyer (QIB), how the anchor portion works, what the lock-in and pricing rules are, and what I ask promoters to prepare before the bankers start investor meetings. The figures are from the ICDR Regulations as I read them; confirm each against the current text.

Who counts as a qualified institutional buyer

QIB is a defined category under the ICDR Regulations, not a label an issuer can give anyone. It covers entities such as mutual funds, foreign portfolio investors (with some exclusions), alternative investment funds, scheduled commercial banks, public financial institutions, insurance companies, and provident and pension funds above a prescribed corpus.

Their share of the net offer depends on the eligibility route. Under Regulation 6(1), QIBs get not more than 50%, with at least 15% for non-institutional investors and at least 35% for retail individual investors; under Regulation 6(2), QIBs must get at least 75%. Within the QIB portion, 5% of the net QIB portion, after the anchor book, is set aside for mutual funds.

QIBs and non-institutional investors cannot withdraw or lower their bids at any stage of the issue. That is one reason a strong QIB book carries weight: those bids are firm.

For context, the other two books are split as well. Retail individual investors bid up to Rs 2 lakh, and the non-institutional portion is divided so that one-third goes to applications above Rs 2 lakh and up to Rs 10 lakh and two-thirds to applications above Rs 10 lakh. Anchors and QIBs sit apart from both.

How the anchor book works

Up to 60% of the QIB portion can be allocated to anchor investors on a discretionary basis. An anchor must be a QIB applying for at least Rs 10 crore, and anchor bidding takes place one working day before the issue opens to the public.

Part of the anchor book is reserved for domestic institutions. It was traditionally one-third for domestic mutual funds, and SEBI widened the reservation in 2025 to include life insurers and pension funds. There are also limits on the number of anchors by allocation size, and restrictions on anchors linked to the lead managers or the promoters.

The anchor price cannot favour the anchor. If the final issue price is higher than the anchor price, anchors pay the difference; if it is lower, they get no refund.

Lock-in: why anchors cannot sell on day one

Shares allotted to anchors are locked in: 50% for 30 days from allotment and the remaining 50% for 90 days. The longer tranche was added to reduce selling pressure soon after listing.

For the company, the lock-in expiry dates are worth marking, because supply can rise when each tranche unlocks. If you have news to announce, such as results or a large order, follow your normal disclosure calendar and do not try to time it around the unlock. Regulation 30 and the insider trading rules apply as they would at any other time.

What anchors look for, and how to prepare

Anchors are usually fund managers who will hold the stock and read the offer document closely. They want a clear business model, key performance indicators that tie to the restated financials, a sensible use of proceeds, sound governance and a valuation that leaves room for returns. They will compare you with listed peers on every metric you disclose.

Preparation starts months before the roadshow. Build an investor presentation that reconciles to the DRHP, prepare management for detailed questions on margins, working capital and related party dealings, and define your KPIs consistently across years. The ICDR publicity rules expect material information shared with investors to be in the offer document, so nothing said in a meeting should go beyond it.

Price discovery: from the price band to the final price

In a book-built issue, the company and the lead managers announce a price band before the issue opens and collect bids within it; the cap of the band is limited relative to the floor. After the issue closes, the final price is set with reference to demand across categories, and QIB demand carries the most weight.

A common mistake is to treat the anchor book as the finish line. A full anchor book at the top of the band, followed by thin QIB demand in the main book, sends a poor signal. I encourage promoters to price for a healthy full book rather than the highest possible anchor price.

Plan for thin demand too. Under Regulation 6(2), failing to allot at least 75% of the net offer to QIBs means refunding everyone. Under 6(1), undersubscription in the retail or non-institutional categories can be met from other categories, and the issue still needs the minimum subscription the rules require.

Frequently asked questions

What is the lock-in period for anchor investors?

Half of the shares allotted to anchor investors are locked in for 30 days from allotment and the other half for 90 days. This reduces selling pressure in the first weeks after listing.

What is the minimum anchor investor application?

An anchor investor must be a QIB applying for at least Rs 10 crore in a main board issue. The number of anchors allowed depends on the size of the allocation.

Does a large anchor book guarantee a good listing?

No. It shows institutional interest at the anchor price, but listing performance depends on the full book, market conditions and valuation. Issuers should aim for broad QIB demand, not only a headline anchor list.

Can promoters or lead managers apply as anchor investors?

Generally not. The rules bar the lead managers and their associates, the promoters and promoter group, and persons related to them from the anchor category, with limited exceptions for certain regulated entities.
