SEBI (Securities and Exchange Board of India)

Definition
India's securities regulator, overseeing public markets, IPOs, and the offer-for-sale (OFS) mechanism that structures many Indian secondary exits, from PhonePe to the NSE's own listing.
Why it matters for a secondary
SEBI's OFS framework is the reason so many marquee Indian secondaries β NSE, SBI Funds Management, Zepto β happen as part of a formal IPO process rather than a private, unregulated transfer.
How it works in practice
SEBI regulates India's securities market, its intermediaries and its listing process, and its rules shape secondaries mainly through the IPO route: what must be disclosed about selling shareholders, which holders can sell in an offer-for-sale, and the lock-in periods that apply to pre-IPO shareholders after listing.
A concrete illustration
A pre-IPO investor buys shares expecting to sell into the listing. Depending on when and how the shares were acquired, a lock-in may prevent any sale for a period after the IPO β so the liquidity event the buyer priced for arrives later than the listing date itself.
What people most often get wrong
In India the difference between 'the company listed' and 'I can sell' is measured in months and is set by rules, not by the market. Confirm the lock-in position for your specific shares and acquisition date before assuming the IPO is your exit.
