Breaking Down India’s Record IPO Month: There Is More Than Meets the Eye

India’s primary market had its biggest month of 2026 in September, even as the broader stock market stumbled. A record 34 companies raised nearly INR 39,380 crore (about USD 4.1 billion) through mainboard IPOs, while 46 companies filed draft papers for mainboard offerings, both all-time highs for a single month.

The surge came against a weak backdrop. The Nifty 50 has fallen roughly 13% this year, making Indian equities among the worst-performing major markets globally. The clearest sign of the split is foreign money. Foreign portfolio investors (FPIs) have put close to INR 54,500 crore into the primary market this year, yet pulled about INR 3 lakh crore out of the secondary market. In simple terms, they are chasing growth in new listings while selling shares that are already listed.

Why are they doing both? Pratik Loonker, Managing Director and Head of ECM at Axis Capital, says foreign investors are being selective, not bullish across the board. “FPIs are investing in quality and larger IPOs, even as they continue to sell in secondary-market equities. This suggests that foreign investors are willing to underwrite specific growth stories at the right price, even if they remain cautious on the broader market,” he said. The real engine, he added, is closer to home: “domestic investors are leading this buyer-led IPO market over foreign investors.”

NSE’s Reality Check

The month was anchored by the National Stock Exchange (NSE) IPO. At INR 22,561 crore, it was India’s second-largest ever after Hyundai Motor India’s INR 27,870 crore issue in 2024, and it made up more than half of September’s fundraising, according to Prime Database. It closed with 5.71x overall subscription, driven by institutional investors, while the retail portion drew only about 1.4 times its quota.

The stock’s run since has been less impressive. NSE was priced at INR 1,785, the top of its INR 1,700-1,785 band, and listed on 24 September at INR 1,800, a premium of under 1%. It touched INR 1,878 within the first hour, valuing the exchange at around INR 4.64 lakh crore, but gave up those gains within days. By 5 October it had fallen to INR 1,712, about 4% below the issue price and nearly 9% below its listing-day high. That erased around INR 41,000 crore of market value from the peak and pushed NSE out of India’s top 10 most valuable listed companies.

Analysts have not turned negative on the business. Macquarie, Emkay and PL Capital have set targets of INR 1,950-2,050, pointing to NSE’s market leadership and growth prospects. But the episode shifts the question from “how big was the listing?” to “what do investors earn after the listing?” It is the same worry raised by Prashant Shah, CEO and Co-founder of Definedge Securities, later in this piece.

From Stalled to September: How the Window Opened

Part of the rush was procedural. “The validity of regulatory approvals for many IPOs were expiring by 30th September,” said TR Prashanth Kumar, Whole Time Director & CEO at Bajaj Capital Securities. “Largely the ones who got a six-month extension due to the US-Iran war. Hence, the higher number of IPOs seen during this period.”

But deadlines alone do not explain why the market could absorb them. The market was not shut earlier in the year (84 mainboard IPOs have come to market so far), but it was hesitant, and September became the window after a long, turbulent stretch. Loonker explains the shift: “The first half was constrained by geopolitical uncertainty and elevated volatility, while global capital also gravitated towards the AI-led trade outside India. In the second half, investors appear to have adjusted to a more prolonged geopolitical backdrop, and volatility too has moderated. Meanwhile, persistent domestic mutual-fund flows have kept institutional liquidity available for quality primary issuance.” The finite validity of approvals, he added, “has also discouraged prolonged deferral,” echoing Kumar’s point on the 30 September deadline.

Domestic retail money has been the quiet support. “An average monthly SIP of around INR 30,000 crore, even amid challenging macro conditions, speaks volumes about the depth and resilience of the domestic investment market,” Kumar said. “With proper spacing between the launches of large-sized IPOs, we do not foresee any major issue with subscriptions.”

Pricing Discipline, Not Desperation

With secondary market sentiment subdued, issuers have had to be realistic on price. “IPOs are being priced more attractively, including at a discount in some cases, to generate investor interest and support subscription,” Kumar said, adding that there is “no one-size-fits-all approach”. The decision to launch depends on how urgently a company needs funds, weighed against how much of a discount it will accept.

Loonker sees discipline rather than distress. “Issuers are increasingly benchmarked against listed peers and must offer credible growth, sensible valuation and adequate aftermarket potential,” he said. And despite the record count, he pushed back on the idea of an undifferentiated rush: “Strong, differentiated issuers are using the available window, while valuation-sensitive companies and large OFS-led transactions remain more timing-conscious. The market can absorb large offerings, but only with credible pricing, broad institutional participation and careful sequencing; excessive clustering may dilute investor attention and increase execution risk.”

Beneath the Headline: A Mixed Month and a Mid-Cap Shift

Subscription patterns told more than one story. Some issues, like Steamhouse India (30.49x) and German Green Steel (29x), saw high-net-worth investors even outpace institutional buyers, typically a sign of short-term, leverage-driven demand chasing listing gains rather than deep conviction. Others, like Runwal Enterprises, closed with tepid interest across the board at just 2.5x, a reminder that a strong headline month can still mask weak individual issues. Listing-day returns were healthy: Prime Database shows the average rising to about 17% in September 2026 from under 1% a year earlier. NSE’s fade shows how quickly a debut pop can disappear.

Kranthi Bathini, Director of Equity Strategy at Wealthmills Securities, noted that appetite for large-cap IPOs, NSE included, has been comparatively low, with mid- and small-cap issues doing distinctly better on investor demand. Retail investors have driven much of this momentum, he said, pointing to roughly three years of heightened activity in this segment, which he linked to the broader “democratisation and digitalisation of the equity market”: easier access, far greater liquidity, and a sharp rise in retail participation.

He cautioned, however, that some of this enthusiasm is short-term. Risk appetite has risen sharply for mid- and small-cap names, with HNIs in particular chasing short-term euphoria rather than sitting through full cycles. His advice to serious investors was to judge a new listing over three to four quarters, even out to 36 months, rather than react to the listing-day pop. He pointed to Paytm and Eternal (formerly Zomato) as stocks that touched their lowest prices well after listing, long after the initial excitement had faded.

The Pipeline Ahead: Selectivity, Not Fatigue

The pipeline looks even larger. According to the Association of Investment Bankers of India, the mainboard IPO pipeline stood at roughly INR 3.86 lakh crore as of September, about 3.5 times the INR 1.10 lakh crore raised through 84 mainboard IPOs so far in 2026.

Asked whether a pipeline this large risks investor fatigue or weaker listing gains, Shah pushed back on the fatigue narrative itself. “Fatigue is less likely than sharper selectivity. Of the INR 3.86 lakh crore pipeline, about INR 1.44 lakh crore is from companies still awaiting SEBI approval, so this supply will reach the market over several quarters rather than all at once.”

His bigger concern is aftermarket performance rather than subscription demand. “The bigger risk is to listing gains and post-listing returns — 7 of the 11 IPOs that raised over INR 9,500 crore each since 2021 now trade below their issue prices, including NSE,” he said. “If mega issues like Jio come at full valuations, expect full subscriptions but thin listing gains.”

What’s Still to Come

Among the big-ticket offerings still to come are Reliance Jio’s share sale, reportedly over USD 3 billion, along with Avaada Electro and Advanta Enterprises. If even a portion of this pipeline converts into listings, 2026 could rival the record years of the past two, both of which crossed USD 20 billion in total IPO fundraising. But as Shah’s data suggests, a strong subscription count will not automatically translate into strong returns once the shares start trading.
