Anchor Investors: How Some AIFs Get Into an IPO Before You Can

By Devansh Singhal · Published · Updated

What is an anchor investor?

An anchor investor is a qualified institutional buyer (QIB) that buys a large block of shares a day before the official launch of the IPO. Retail investors cannot apply in this category. Mutual funds, insurers, pension funds, banks and foreign institutions are the usual names. SEBI-registered AIFs can also appear in anchor books, subject to the investment conditions in their own regulations and offer documents. 

How the process works-


  1. Anchor bidding happens one working day before the issue opens. The company, with its lead managers, chooses who gets shares and at what price within the band.

  2. The allocation is disclosed. The names of anchor investors and their allocations are made public before the issue opens. 

  3. The IPO opens to everyone else. Retail, non-institutional and other QIB investors bid during the subscription window.

  4. Lock-in applies. 50% of the anchor allocation stays locked for 30 days and the rest for 90 days from allotment, for issues opening on or after April 1, 2022.The rules that shape the anchor book

The framework was reworked recently, so older articles may be out of date:


  • Reservation: The overall reservation for the anchor portion was raised to 40% from 33%: 33.33% for mutual funds and 6.67% for insurers and pension funds, with any unsubscribed insurer and pension share going back to mutual funds. business-standard

  • Minimum ticket: For allocations up to ₹250 crore, SEBI merged two earlier categories and set a minimum of 2 and a maximum of 15 anchor allottees, with at least ₹5 crore per investor. The earlier minimum was ₹10 crore. 

  • Larger issues: For anchor portions above ₹250 crore, every additional ₹250 crore or part thereof allows 15 more investors. business-standard

  • Cap: Anchors can take up to 60% of the QIB portion, which is where the bulk of discretionary allocation goes.

Where AIFs fit in-


A QIB with a ₹5 crore ticket is not an individual. It is an institution, and an AIF is a pooled vehicle. If you hold ₹1 crore in an AIF (the minimum commitment), you are not an anchor investor. The fund is, and your share of any gain depends on the fund’s size, strategy, fees and what it does after the lock-in ends.

That distinction matters, because “our fund participates in anchor books” is a claim about access, not about returns. Access has real advantages: early visibility into the issue, a known price before the public opens and a disciplined entry. But it is not a guarantee. The shares still trade freely once the lock-in ends, and the anchor price is not a profit. In a typical example, an anchor who bid at ₹500 still has to pay the difference if the final IPO price is fixed at ₹520, so there is no price advantage.

What the anchor “tag” does and doesn’t tell you


What it does tell you:

  • Large institutions did their diligence and committed capital early.
  • The issue has a base of demand before it opens, which can reduce early volatility.

What it doesn’t tell you:

  • That the stock will rise after listing. Anchor investors are not endorsing future performance, and retail investors should not rely solely on anchor data when evaluating an IPO.
  • That the AIF will make money. Lock-in expiry can bring selling pressure, and the shares are marked to market like anything else.

Questions to ask an AIF that talks about IPO access


  1. Is anchor participation part of the stated strategy, or an occasional opportunity? Check the PPM.

  2. What is the track record? How many anchor allotments, at what prices, and what happened after the 30 and 90 day lock-ins?

  3. How are exits decided? Is there a policy, or is it discretionary?

  4. How are gains valued and charged? Are unrealised mark-ups included in performance numbers, and when does carry apply?

  5. What is the concentration? One large anchor allocation in a fund can dominate its results.

The bottom line

Anchor allocation is a legitimate way for institutions, including some AIFs, to enter an IPO ahead of the public. It reflects early commitment, not guaranteed returns. When an AIF cites IPO access, treat it as a starting point and judge the fund on net IRR, DPI and discipline, not on the headline.
