IPOs are changing – and so are the rules
If you feel like IPOs today look a little different from the ones you saw a few years ago, you are not imagining it. India’s primary markets have gone through a strong cycle of tech listings, SME IPO booms and bouts of volatility, and the regulator has been quietly updating the rulebook to keep pace.
Over the past few years, the Securities and Exchange Board of India (SEBI) has tightened and refined IPO norms in several areas – from how long anchor investors must stay locked in, to how pre-IPO shareholders can sell, and most recently, how pledged shares are treated during lock-in. These changes are not just legal fine print; they affect how much “skin in the game” promoters and large investors have, how stable post-listing prices may be, and how safe the playing field is for retail investors.
This article breaks down SEBI’s new IPO norms in simple language, focusing on what has changed around lock-in periods, pledged shares and promoter holdings, and what all this means for everyday investors applying through UPI and ASBA.
Quick refresher: How IPOs and SEBI norms work
An initial public offering (IPO) is when a company sells its shares to the public for the first time, listing on a stock exchange and opening up ownership to retail, institutional and high-net-worth investors. SEBI’s job is to ensure that this process is fair, transparent and does not disadvantage smaller investors.
To do this, SEBI issues and regularly amends the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 – commonly called the ICDR Regulations – which lay down rules on eligibility, disclosures, pricing, lock-ins, and more. Over time, these regulations are tweaked through circulars and notifications based on market feedback, misuse cases and evolving conditions.
Recent changes in IPO norms mainly impact three areas:
- How long pre-IPO shareholders, promoters and anchor investors must stay locked into their holdings.
- How pledged shares – shares given as collateral to lenders – are treated during lock-in.
- How companies and intermediaries must disclose and operationalise these rules.
The big shift: Stronger lock-in rules for anchor investors
Anchor investors are large institutional investors – such as mutual funds, insurance companies, sovereign wealth funds and foreign portfolio investors – invited to bid for shares one working day before the IPO opens for everyone else. Their participation signals institutional confidence in the issue and helps build momentum for the offer.
What the rules used to be
Earlier, the general practice was that anchor investors had to stay invested for only 30 days from the date of allotment. After that, they were free to sell their entire holding, which sometimes led to heavy selling pressure soon after listing and price volatility that hurt retail investors who had just entered.
What SEBI changed
SEBI introduced a two-tier lock-in structure for anchor investors in mainboard IPOs:
- Only 50 percent of the anchor allotment can be sold after 30 days from allotment.
- The remaining 50 percent is locked in for 90 days from allotment.
In other words, at least half of the anchor investors’ money must stay in for three months, giving the stock some breathing room beyond the immediate listing hype.
Why this matters for you
- It reduces the risk of a sudden “anchor exit” wave crashing the stock price just a month after listing.
- It aligns anchor investors’ interests with regular investors for a longer period, because they have more to lose if the stock performs poorly soon after the IPO.
For retail investors, this change means that the initial post-listing phase is less likely to be dominated by short-term anchor profit-booking.
The latest move: Lock-in on pledged shares via ‘non-transferable’ tagging
One of the most important new IPO norms – and a relatively technical one – deals with pledged shares. These are shares that promoters or pre-IPO shareholders have given as collateral to lenders in exchange for loans.

The problem SEBI spotted
Under existing ICDR rules, pre-issue capital held by persons other than promoters (with some exceptions) must be locked in for six months from the date of allotment in an IPO. However, issuers pointed out a gap: what happens when those shares have already been pledged before the IPO? Creating a conventional lock-in on pledged securities is not always straightforward.
This created a potential loophole. In theory, pledged shares could change hands or be enforced by lenders during the lock-in period in ways that undermined the spirit of the rules, which are meant to ensure continuity and commitment from pre-IPO shareholders.
SEBI’s new solution
In March 2026, SEBI amended the ICDR Regulations and, through an April 8, 2026 circular, introduced a new mechanism:
- Where a traditional lock-in cannot be created on pledged shares, depositories are now allowed to mark such securities as “non-transferable” for the duration of the applicable lock-in period.
- This “non-transferable” tag ensures that, even if the pledge is invoked or released, the shares in the beneficiary’s account (pledger or pledgee) remain effectively locked in until the lock-in period ends.
To make this work, SEBI has placed the following responsibilities on issuers and intermediaries:
- Issuers must:
- Amend their Articles of Association to reflect the new mechanism.
- Inform lenders or pledgees about the restrictions.
- Make clear disclosures in their draft offer documents and RHPs.
- Depositories must:
- Update systems to allow non-transferable tagging and automatic lock-in of such shares.
- Ensure that after pledge invocation or release, the shares are automatically locked in for the remaining period.
- Stock exchanges and merchant bankers must monitor and ensure compliance.
Why this matters for you
For retail investors, this change means:
- Promoters and significant pre-IPO shareholders can no longer use pledging structures to “escape” lock-in obligations.
- The quality of pre-IPO shareholding becomes more transparent and predictable, reducing governance risks.
- The stability of the shareholding pattern in the crucial first months after listing is better protected.
In short, the move plugs a long-standing gap in IPO norms and strengthens confidence that everyone is genuinely locked in as promised.
Other key lock-in related norms you should know
While the latest headlines are about pledged shares, they build on a broader set of lock-in rules that SEBI has tightened over the last few years.
Key lock-in norms at a glance
| Category of shareholder | Typical lock-in requirement* | Recent tweaks / clarifications |
|---|---|---|
| Promoters (minimum contribution) | Longer lock-in (often 3 years for a specified portion; shorter for balance, as per ICDR) | Greater scrutiny on use of IPO proceeds and encumbrances, plus new pledged-share mechanism to ensure effective lock-in |
| Other pre-IPO shareholders | Generally 6 months lock-in from allotment, with exemptions for certain categories | Clarified that where shares are pledged, depositories can apply “non-transferable” tag to enforce lock-in |
| Anchor investors | 50% of allotment locked in for 30 days; remaining 50% locked in for 90 days | Two-tier lock-in introduced to prevent abrupt full exits after 30 days |
*Exact periods and conditions can vary depending on issue structure and applicable ICDR provisions.
These rules collectively aim to ensure that key shareholders cannot quickly cash out after listing, leaving retail investors holding the risk.
How SEBI’s new IPO norms impact different stakeholders
1. Promoters and pre-IPO shareholders
For promoters and early backers (like PE/VC funds), the non-transferable tagging of pledged shares tightens the circle around their holdings during the lock-in period. They now have to:
- Factor lock-in implications into financing decisions and pledge structures well before filing for an IPO.
- Work closely with lenders and depositories to ensure documentation and systems are aligned.
- Accept that creative arrangements to side-step lock-ins will be harder to execute.
Over time, this is likely to encourage more conservative pledging practices and better-capitalised businesses coming to market.
2. Anchor investors
The extended two-stage lock-in makes IPO allocations less of a quick trading opportunity and more of a medium-term commitment. For serious institutional investors this fits well with long-term mandates; for short-term players, it reduces the incentive to participate purely for listing gains.
In practice, this should:
- Improve the quality of anchor books.
- Provide more confidence to retail investors that anchor names are not just “tourists” exiting at the first opportunity.
3. Retail investors
For retail investors applying through UPI or ASBA, SEBI’s new norms do not change the application process, but they change the risk environment around IPOs.
Potential benefits include:
- More genuine skin in the game from promoters and early backers.
- Reduced chance of sudden institutional exits that could trigger sharp price drops soon after listing.
- Clearer disclosures about pledged shares and lock-in arrangements.
However, it is still up to each investor to evaluate fundamentals, valuation and their own risk appetite before applying.
SEBI’s broader agenda: Governance, transparency and market stability
The new IPO norms do not exist in isolation. They are part of a broader series of steps SEBI has been taking to strengthen market governance and investor protection.
In recent board meetings and circulars, SEBI has:
- Tightened disclosure rules for foreign portfolio investors (FPIs) with large concentrated positions, to enhance transparency.
- Set up committees to review conflict-of-interest norms and governance standards for market infrastructure institutions.
- Introduced new investor-friendly features like a “debit freeze” or lock-in facility for mutual fund units, so investors can voluntarily ring-fence investments from impulsive withdrawals.
Seen in this context, the new IPO norms are part of a consistent push: make it harder to game the system, make real risks more visible, and encourage more informed, long-term participation.
What this means for how you should think about IPOs
SEBI’s new norms make IPOs structurally safer, but they do not magically make every IPO a good investment. Retail investors still need a simple, disciplined framework to evaluate offers.
1. Don’t rely only on “who is coming along”

Anchor participation and strong pre-IPO investors matter, and SEBI has now made their commitments stickier. But even with longer lock-ins, institutional investors can still get their thesis wrong or have different time horizons from you.
Use anchor and pre-IPO shareholder information as a data point, not a substitute for your own homework.
2. Read the sections on use of proceeds and shareholding
SEBI has become increasingly strict about how IPO proceeds can be used and how clearly this must be disclosed. Before applying, look at:
- How much of the issue is fresh capital versus offer for sale (OFS) by existing shareholders.
- Whether the company is raising money for growth (capex, expansion, debt reduction) or mainly providing exits.
- The post-issue shareholding pattern – how much stake promoters and key investors retain after the IPO.
3. Respect the lock-in, but don’t ignore fundamentals
Stronger lock-ins and tagging of pledged shares mean that key players are tied in for longer. That is positive for alignment, but it does not guarantee returns. Focus on:
- Revenue growth, profitability, cash flows and leverage.
- Industry structure and competitive position.
- Valuation versus listed peers.
The new norms are like better seat belts in a car – they improve safety, but you still need to drive carefully.
Questions to ask before applying for an IPO
You can even turn this into a personal checklist before every IPO application.
Will the new IPO norms reduce listing-day pops?
Many investors love IPOs for the potential of quick listing gains. Stronger lock-ins and better enforcement for pledged shares may slightly cool the “flipping” culture, particularly among large investors.
In the short term, this could mean:
- Fewer extreme cases where heavy anchor selling crashes the stock soon after listing.
- More stable price discovery as the free float evolves more gradually.
In the longer term, if only better-quality businesses with cleaner governance and realistic valuations come to market, the overall risk–reward for IPOs may become healthier. But that also means investors will need to be more selective instead of applying blindly to every issue.
How investors can adapt
If you see yourself as a long-term, goal-based investor rather than a pure trader, SEBI’s new IPO norms are broadly in your favour. Here is how you can adapt your approach:
- Treat IPOs as one of many ways to build equity exposure, not the primary one. A diversified mutual fund or ETF portfolio often deserves first priority.
- When considering an IPO, apply the same discipline you would apply to buying any stock – fundamentals, valuation, governance, and fit with your overall asset allocation.
- Use SEBI’s new disclosures on lock-ins and pledged shares as a governance filter. If something looks complicated or uncomfortable, it’s okay to skip the offer.
Over time, a mix of stronger regulations and better-informed investors can make India’s primary markets deeper, more transparent and more rewarding.
Key takeaways
- SEBI has introduced stricter lock-in norms for anchor investors, requiring them to hold at least half their IPO allocation for 90 days, reducing the risk of abrupt exits and post-listing price shocks.
- A new mechanism now allows depositories to tag pledged pre-IPO shares as “non-transferable” when a conventional lock-in cannot be created, ensuring that such shares stay effectively locked for the required period.
- Issuers must amend their Articles, inform lenders, and make clear disclosures, while depositories and exchanges upgrade systems and monitoring, collectively plugging long-standing gaps in IPO governance.
- For retail investors, these norms mean better alignment of interests and more transparent risk, but do not remove the need for thorough fundamental analysis and self-awareness about risk appetite.
