Insights from 11 Years of Mainboard IPOs

A Record Year That Signals Depth, Not Excess

India’s IPO market reached a new high in 2025, raising ₹1.76 trillion — roughly 50% more than the previous peak in 2021. The year also recorded the highest number of listings in more than a decade.

Yet the surge does not resemble the speculative spikes typical of earlier cycles. Median offer size stood at ₹7.2bn — only slightly above the decade median of ₹6.5bn — indicating a mix of both large and mid-sized companies rather than a handful of oversized listings. Fresh capital issuance remained substantial, suggesting firms were raising funds for growth rather than relying primarily on shareholder exits.

In other words, the market’s expansion reflects breadth as much as scale. India’s exchanges appear increasingly capable of absorbing companies across sectors and sizes, pointing to resilience rather than froth.

Private Capital Produces Disproportionate Outcomes

Although only one in five IPOs over the past decade involved private equity or venture capital backing, these companies accounted for roughly a quarter of total capital raised — about ₹1.9 trillion.

Their listings also tended to be larger and more richly valued. PE- and VC-backed firms went public at an average price-to-sales multiple of 5.4 times and generated more than ₹1 trillion in liquidity through OFS sales over the period.

In 2025 alone, 21 such companies raised ₹525bn. The data suggest that private capital is not merely producing more listings but shaping larger outcomes — aligning India’s capital markets more closely with global venture and private equity cycles.

Venture Funding Accelerates the Path to Market

Private capital also appears to be compressing the corporate life cycle. Companies backed by PE or VC typically listed about four years earlier than their non-PE/VC backed peers. The median age at IPO was roughly 16 years for PE/VC backed firms, compared with 20 years for others.

The findings reflect the influence of institutional investors in professionalising governance, strengthening balance sheets and preparing companies for public scrutiny. The IPO, once viewed as a distant milestone after decades of operations, is increasingly becoming a strategic stage in a company’s growth trajectory.

IPOs Are Becoming Balance-Sheet Tools

Across recent listings, fresh capital has largely been directed towards debt repayment, capital expenditure and working capital — consistent with patterns observed over the past decade.

The implication is significant: the IPO is evolving from a liquidity event into a mechanism for financial restructuring and growth funding. India’s public markets are increasingly acting as providers of expansion capital rather than merely venues for investor exit.

Conclusion

Taken together, the numbers point to a market undergoing structural transformation. Since 2015, Indian IPOs have raised ₹7.4 trillion and delivered a combined market capitalisation of nearly ₹49.8 trillion at offer price.

Such scale suggests a steady widening of the investor base, greater institutional participation and deeper integration between private and public capital pools. Rather than marking the end of a company’s journey, the public markets are becoming the next stage of corporate expansion. For founders, investors and policymakers alike, the message is clear: India’s IPO market is no longer merely cyclical. It is compounding.
