Beyond metros: How Bihar is quietly powering India’s fastest-growing investor base

With the talk on Dalal Street now focused on every new investor trying to make a quick buck from the stock market, the reality of India’s investor base appears to be shifting beyond the metro cities, as people from across the country now seek to be part of the growing emerging market story.

As NISM data suggest that more than eight crore Indians open their trading applications every day to invest in the equity markets, the next crowd of stock market investors is likely to come out of an emerging Tier-2 city like Bihar rather than an average Joe from Mumbai.

Low-cost trading platforms, a surge in digitisation in the economy, and rising public interest in the equity markets have translated to massive investor participation across the stock exchanges in the last five years, or the post-COVID era.

Investor base surges past 12 crore

In a country of around 147 crore people, NSE’s registered investor base stood at 12.9 crore as of the year ended March 2026, marking a 14.4% year-on-year (YoY) growth compared to the previous fiscal year.

Although this number may look significantly smaller compared to the population of the country, data showed that it took around 14 years for the Indian stock market to reach 1 crore registered investors since the beginning.

“Today, it takes just 5 to 7 months on average to add an incremental crore,” according to NSE’s latest Market Pulse report issued in April 2026.

In March 2026, the net addition of investors was at 12.3 lakh, witnessing a 7.7% month-on-month drop as markets witnessed extreme volatility due to the supply chain disruption caused by the US-Iran conflict in West Asia.

Despite this fall, the total number of unique client codes (UCC), the alphanumeric identification number assigned by every stockbroker to its investors, crossed 25 crore as of the financial year ending 2025-26, highlighting strong public interest in the stock markets.

States such as Maharashtra, Uttar Pradesh, and Gujarat remain the top contributors to the overall investor base in the equity markets.

Data showed that Maharashtra, which holds the financial capital of the nation, Mumbai, continues to lead the registered investor count in the financial year ended 2025-26 with more than 2 crore investors contributing to 15.6% of the total investor base in the country.

Uttar Pradesh and Gujarat follow Maharashtra’s lead, coming in at 1.5 crore investors (11.7% market share) and 1.1 crore investors (8.5% market share), respectively. These three states, along with West Bengal and Rajasthan, collectively make the top 5 Indian states to account for rising market investors in the country.

With a focus on the top 5 states for the majority contribution, people often overlook the rising share of emerging states like Bihar, which, despite not falling under the top ranks, has emerged as the fastest-growing region in terms of investor base in the last five years.

How big is Bihar’s investment hub?

NSE data suggests that Bihar has emerged as the fastest-growing state for investors, recording a 5.8x jump since the financial year ended in 2020-21. Hence, in the last five years, Bihar, which is known for ‘makhanas’ and culture, now ranks among the top 10 in the list, indicating deep capital market penetration.

“Among the top 10 states, Bihar has grown the fastest, with its investor base jumping 5.8x since FY21. Its ranking also improved from 14th in FY21 to 10th currently,” according to NSE’s recent report.

Data also showed that as of the financial year ended 2025-26, the total unique registered investors in Bihar were 60,11,000 or 60.11 lakh people, accounting for 4.7% of the total shares in the capital market.

In comparison, Bihar had 50,85,000 or 50.85 lakh investors in FY2024-25 (4.5%); 6,70,000 or 6.7 lakh investors in FY2019-20 (2.2%); and 2,94,000 or 2.94 lakh people in FY2014-15 (1.6%).

Like Bihar, other states such as Arunachal Pradesh, Assam, Mizoram, and others have emerged as significant movers in their investor base in the last five years. Data suggests that the regions outside the top 10 now account for 27% of the investor base in India.

“The multi-fold growth in smaller states, largely comprising Tier II and Tier III cities, reflects deeper penetration of capital markets beyond traditional financial centres,” said NSE in its latest report.

Among the top 10 states in India, four recorded more than a 10x growth in the number of active investors, with Bihar leading the pack with a 21x increase in active investors of around 14 lakh people.

In conclusion, a state with a projected gross domestic product (GDP) of ₹13.1 lakh crore for the financial year ending 2026-27 has successfully emerged as one of the biggest movers in the country in terms of people investing in the financial markets.

Although the benchmark stock index NIFTY50 has lost close to 8% so far in 2026, due to the geopolitical impact on India caused by the West Asia crisis and supply disruptions, people’s faith in the Indian markets has remained strong over the years.

This strategic shift is likely to drive India into a consumption boom, which shields the domestic markets from foreign cues and impacts with fundamental support from the domestic investors. A similar trend was witnessed by investors during the FII exodus in March 2026, when domestic investors stepped up for the opportunity.
