NSE Options Market Share Falls to 68.48% in June 2026

NSE's share of India's equity options market, measured by premium turnover, fell to 68.48% in the quarter ended June 30, 2026, from 78.63% a year earlier. The figures in its September 10, 2026 red herring prospectus show a weaker competitive position in the exchange's largest revenue-generating trading segment.

NSE remained the leading venue on this measure. However, the 10.15 percentage-point decline over comparable June quarters contrasts with its much higher shares in cash equities and equity futures. That difference makes segment-level data more informative than a single description of NSE's overall market leadership.

How much has NSE's options market share fallen?

The RHP's industry comparisons, attributed to the commissioned Redseer report, show a sustained reduction in NSE's annual share of equity options premium turnover. It fell from 96.86% in FY2024 to 87.43% in FY2025 and 74.71% in FY2026.

The FY2026 annual decline was 12.72 percentage points compared with FY2025. The June 2026 figure was 28.38 percentage points below the FY2024 annual figure, although that longer comparison combines a quarter with a full year.

For a cleaner assessment of the latest disclosed change, the two June quarters provide a like-for-like period comparison. Percentage points describe the difference between the two market shares; they should not be labelled as the percentage decline in NSE's trading volume.

What does options premium turnover measure?

Options premium turnover measures the value of premiums traded. The RHP separately presents equity options notional turnover, which is a different measure. A market-share statement needs to identify which basis it uses.

The 68.48% figure concerns premium turnover in equity options. It does not describe NSE's share of all Indian securities trading, its share of listed companies or its proportion of market capitalisation.

This precision matters because exchanges can have different positions across products. The RHP's segment comparisons on pages 202–203 show that NSE's competitive position in options differed materially from its position in equity futures.

Did NSE's own options trading volume also fall?

NSE's average daily equity options premium turnover increased in the June 2026 quarter despite the decline in market share. It rose to ₹64,351.78 crore from ₹55,513.61 crore in the June 2025 quarter.

Both statements can be true because market share is a relative measure. NSE can process more premium turnover while accounting for a smaller proportion of industry activity. Its own growth is therefore insufficient evidence that it is maintaining its competitive position.

The annual figures tell a different volume story. Average daily options premium turnover fell to ₹57,661.75 crore in FY2026 from ₹62,448.66 crore in FY2025. Annual weakness and June-quarter growth should be reported separately rather than combined into a single direction of travel.

How does the decline compare with other NSE markets?

NSE held 93.05% of the cash market and 99.72% of equity futures in the June 2026 quarter, according to the RHP. The corresponding June 2025 shares were 93.80% and 99.77%.

The changes in those segments were much smaller than the decline in options premium share. The evidence therefore supports a specific account of options competition, rather than a broad claim that NSE was losing its leading position across every market.

The prospectus discusses competitive pressures, but the share series alone does not establish how much of the movement resulted from each competing product, participant decision or regulatory change. Assigning a single cause would go beyond what these figures demonstrate.

Why does options market share matter for NSE?

Options transaction charges contributed 60.22% of NSE's operating revenue in FY2026. A change in competitive share within this segment consequently has more financial relevance than its percentage alone might suggest.

Revenue still depends on absolute activity and realised transaction charges, as well as market share. NSE's disclosures show why all three need to be considered together: its June-quarter options activity increased while its premium turnover share declined. The central finding is a measurable weakening of relative options market share within a business that continued to lead the market.
