What happens to unlisted and pre-IPO shares when the company lists — how they become listed shares, how SEBI lock-in periods work, and the risks before treating a listing as a payday.

Many people buy unlisted or pre-IPO shares hoping to benefit when the company finally lists. But what actually happens to those shares on IPO day — and can you ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​sell immediately? The answer usually involves a lock-in. This explainer sets out, factually, what happens to your unlisted shares after the company’s IPO, how lock-in periods work in India, and the risks to understand first. It is information, not investment advice.

What happens to your shares at listing

When a company completes its IPO and lists, your unlisted shares become listed shares. They keep the same ISIN and sit in the same demat account, but they are now admitted to trading on the NSE or BSE — so, in ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​principle, they gain a live market price and an exchange to trade on. The important words are “in principle,” because a lock-in often stops you from selling right away.

Lock-in periods: the key thing to understand

To stop pre-IPO holders from dumping shares the ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​moment a stock lists, SEBI’s rules impose lock-in periods on shares held before the IPO. During a lock-in, the shares are yours but cannot be sold or transferred. Broadly:

The exact durations are set by SEBI’s ICDR regulations and can change, and specific holdings may carry their own contractual lock-ins on top. Always verify the current rules ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​and read the company’s prospectus (DRHP/RHP) for the lock-in that applies to your shares.

Why lock-ins exist

Lock-ins protect new public investors. If every pre-IPO holder could sell on day one, a flood of supply could destabilise the price right after ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​listing. The lock-in staggers when early holders can exit, which supports a more orderly market in the initial months.

What you can and can’t do during lock-in

After the lock-in ends

Once the lock-in expires, the shares become freely tradable on the exchange like any other listed stock — you can sell through your broker at the ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​prevailing market price. Note that a wave of lock-in expiries can itself influence the share price, as more supply becomes available at once.

Tax, in brief

Selling after listing is taxed under the rules for listed securities, which differ from those for unlisted shares, and the treatment depends on ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​your holding period. This is a factual flag, not tax advice — the holding period and cost basis for pre-IPO shares can be nuanced, so consult a qualified professional.

Frequently asked questions

Can I sell my pre-IPO shares on listing day?

Usually not, if they are subject to a lock-in. Pre-IPO holdings are commonly locked in for a period after allotment; you can sell only once that lock-in ends. Check the ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​prospectus for the lock-in that applies to your shares.

Do my unlisted shares automatically become tradable when the company lists?

They become listed shares with the same ISIN, but whether they are tradable depends on ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​any lock-in. After listing and once any lock-in expires, they trade like a normal listed stock.

Why is there a lock-in at all?

To prevent early holders from selling en masse immediately after listing, which supports a more orderly price in the first months of trading.

Where do I confirm the lock-in on my shares?

The company’s Red Herring Prospectus and SEBI’s ICDR regulations are the authoritative sources; ​​​⁠​​​⁠​​​​⁠​​⁠⁠​⁠⁠​​​⁠​⁠​⁠⁠⁠​​​⁠​⁠⁠⁠⁠⁠⁠​​⁠⁠⁠​⁠​​​⁠⁠​​​⁠​​​⁠​⁠​⁠​⁠⁠⁠​⁠⁠​​⁠⁠​⁠⁠​⁠⁠​⁠​⁠​​contractual lock-ins may also apply. Verify the current rules rather than relying on general summaries.
