National Stock Exchange (NSE) will pay nearly Rs 1,491 crore to settle long-pending regulatory cases with the Securities and Exchange Board of India (Sebi), after the regulator accepted the exchange's revised settlement terms in principle, according to Business Today. The settlement paves the way for NSE's initial public offering (IPO), for which the exchange has already filed the offer document.
Sebi accepts revised settlement terms
In a statement, NSE said it has received a communication dated July 30, 2026, from Sebi regarding the in-principle acceptance of the Revised Settlement Terms proposed by the exchange. Business Today reported that Sebi has made a demand of Rs 714.74 crore from NSE, in addition to the deposit of Rs 776.47 crore made by NSE with Sebi, which will be adjusted towards the settlement amount. Together, the two components aggregate to approximately Rs 1,491 crore.

The co-location and dark-fibre cases explained
The cases, popularly referred to as the co-location case and the dark-fibre case, involved several former top officials of NSE who allowed preferential access to the exchange's trading systems and related data to some brokers for making illegal gains, according to Business Today.
In its IPO prospectus filed last month, NSE had disclosed that it submitted a revised settlement term with Sebi for settling these cases. The proposal offered to settle the co-location case for Rs 1,223.6 crore and the dark-fibre case for Rs 267.7 crore.
| Case | Amount offered (Rs crore) |
|---|---|
| Co-location case | 1,223.6 |
| Dark-fibre case | 267.7 |
| Total offer | 1,491.3 |
A multi-year process reaches resolution
The settlement issue had been under process for several years, according to Business Today. The in-principle acceptance now "paves a smooth sailing of NSE's IPO," the report said, underlining that the exchange has already filed the offer document for its public listing.
What this means for investors and market participants
For CFOs, treasury directors and institutional investors tracking India's capital markets, the settlement is a concrete resolution of legacy enforcement matters at the National Stock Exchange. The aggregate payout of nearly Rs 1,500 crore reflects the financial weight of the regulatory action, while the settlement structure — an earlier deposit of Rs 776.47 crore plus a fresh demand of Rs 714.74 crore — shows how such obligations are sequenced over time.
The resolution also removes a key uncertainty around NSE's IPO, which had been flagged by the exchange's prospectus disclosure. With the co-location and dark-fibre cases settled in principle, investors evaluating the offering can now assess the exchange's regulatory standing without the overhang of pending enforcement action. The settlement, reached through Sebi's in-principle acceptance, demonstrates a path for resolving long-pending regulatory proceedings.
