IPO lock-in expiry: Nuvama estimates 99 companies could make about $24 bn of shares eligible for trading from Oct 2026 to Jan 2027. Promoters hold a large portion; actual selling is uncertain. About Rs 2.3 lakh cr at Rs 95.8 per dollar (my calculation).
Quick Answer
IPO lock-in expiry will make about $24 billion worth of shares from 99 companies eligible for trading between October 2026 and January 2027, according to a Nuvama Institutional Equities estimate, and promoters hold a large part of that amount. Eligible does not mean sold, because many promoters and long-term investors hold on, but a sudden rise in tradable supply can add short-term selling pressure and volatility. At about Rs 95.8 per dollar the amount is roughly Rs 2.3 lakh crore, or about $242 million per company on average (my calculation). Investors should track unlock dates, who is being unlocked and how much of the free float they represent before buying or selling.
IPO lock-in expiry is one of the most predictable supply events in the market, yet many investors learn about it only after the share price falls. A lock-in is a period after listing when certain shareholders cannot sell, and when it ends their shares can be traded freely.
This guide explains how a lock-in works, the Nuvama estimate for October 2026 to January 2027, what happened in an earlier period, why prices can move around unlock dates, and a checklist for investors.
A note on the numbers: I could not open the Nuvama report for this period. The $24 billion, 99 companies and the promoter comment come from the headline, and the history below is from an earlier Nuvama report on a different period.

How an IPO Lock-In Works
| Shareholder | Typical lock-in under current SEBI rules | Note |
|---|---|---|
| Anchor investors | 50% for 30 days and the rest for 90 days | Starts from allotment |
| Pre-IPO investors | 6 months from allotment in the IPO | Includes venture and private equity funds |
| Promoters, minimum contribution | 18 months | Required share of post-issue capital |
| Promoters, excess holding | 6 months | Shares beyond the minimum |
These are the commonly quoted periods and can vary by issue type, so check each prospectus. The point is that an IPO lock-in expiry arrives in steps, not all at once.

What an Earlier Nuvama Report Showed
| Item | Earlier report |
|---|---|
| Period | 6 January to 30 April 2026 |
| Companies | 96 |
| Value | About $45 billion |
| Promoters | A sizeable portion held by promoters and promoter group entities |
| Comment | Lock-in expiries often cause temporary volatility and short-term selling pressure |
Examples from that report include about 1.1 crore Meesho shares (about 2% of equity) on 7 January, about 1.5 crore Wakefit shares (5%) on 12 January and about 70 lakh ICICI Prudential AMC shares (1%) on 16 January. The percentages show how small many unlocks are against the full equity, which is why the effect on each IPO lock-in expiry varies.
Why Prices Can Move Around an IPO Lock-In Expiry
- Supply: more shares become available, which can weigh on the price if holders sell.
- Anticipation: traders may sell ahead of the date and buy back after.
- Seller type: venture and private equity funds usually sell, while promoters rarely do.
- Free float: a stock with a small free float can swing more when a block unlocks.
- Market mood: in a weak market the same unlock has a bigger effect.
The effect of an IPO lock-in expiry depends more on who can sell and how much than on the date itself.
Checklist: How to Read an IPO Lock-In Expiry
| Question | Where to look | Why it matters |
|---|---|---|
| How many shares unlock? | Exchange lock-in disclosure and prospectus | Larger share of equity means more potential supply |
| Who owns them? | Shareholding pattern | Promoters are less likely to sell than funds |
| Is it a fund nearing exit? | Fund life and past sales | Older funds may sell sooner |
| How liquid is the stock? | Average daily volume | Low volume magnifies moves |
| What did the price do before? | Chart over recent weeks | A run-up can be followed by selling |
Many investors check only the headline figure. Checking the holder type and percentage gives a better view of the real risk from an IPO lock-in expiry.
Risks Around an IPO Lock-In Expiry
Selling by early investors: At an IPO lock-in expiry, venture and private equity funds may sell once they are free to exit.
Weak market: The Sensex and Nifty 50 are under pressure, which can magnify the effect of new supply.
Crowded IPO pipeline: New listings, including large issues, compete for the same investor money.
Headline bias: A big IPO lock-in expiry number can scare investors even if actual selling is small.
Missing detail: The company list and dates behind the $24 billion were not available to me.

Conclusion
IPO lock-in expiry will free about $24 billion of shares across 99 companies from October 2026 to January 2027, but actual selling is uncertain and promoters hold a large portion. Check the unlock date, the holder and the percentage for each stock you own. Consult a SEBI-registered advisor before making any decision.
