India IPO market splits in 2026 as mainboard stalls

A market that has turned into two separate stories

India’s IPO cycle is showing a clear split in 2026. The mainboard market, which delivered record fundraising over the last two years, has slowed sharply as geopolitical tensions in West Asia raise uncertainty and push investors into a risk-off posture. At the same time, the SME segment continues to see steady issuance, driven largely by retail participation. The result is a primary market that is still functioning, but with a narrower risk appetite and tougher scrutiny on pricing.

This divergence matters because it changes how companies time listings and how investors assess primary market risk. It also signals that liquidity has not disappeared, but it is being directed differently across segments.

May 2026: a rare zero month for mainboard IPOs

The slowdown is most visible in the mainboard segment. May 2026 passed without a single mainboard IPO, the first such month since March 2025, when US tariff announcements had unsettled global markets. The absence of new deals underlines how quickly sentiment can change when global uncertainty rises.

The mainboard silence has also been visible in shorter windows. The market saw no new mainboard listings for two consecutive weeks, even as activity continued elsewhere in the primary market.

Record fundraising in FY26, then a sudden pause

The slowdown comes shortly after an unusually strong period. Indian companies raised an all-time high of ₹178,000 crore through mainboard IPOs in FY26, surpassing the previous peak of ₹162,000 crore in FY25, according to Prime Database data. That record created expectations of a sustained pipeline, but 2026 has brought a recalibration.

In the first three months of 2026, primary market activity still looked healthy. Eighteen companies launched mainboard IPOs and raised ₹18,928 crore, compared with ₹15,723 crore in the same period a year earlier. But the momentum weakened in April as the impact of West Asia tensions hit sentiment more directly.

Startups slow down as volatility disrupts timelines

After a strong bull run in IPOs over two years, several Indian startups are now delaying listing plans. The US-Iran war has disrupted timelines, with companies going slow on filing draft papers and reassessing readiness for volatile markets.

PhonePe pressed pause on its $1.3 billion IPO that was initially slated for a launch sometime in April. Flipkart is also understood to be in no rush with IPO preparations amid wobbling markets. While some large issues such as Zepto and Oyo are described as being in the pipeline, they are unlikely to reach the market if volatility persists, according to industry executives cited in the article.

Weak listing outcomes are reinforcing caution

Investor selectivity is being shaped not just by geopolitics but also by listing performance. The article notes that only six new-age companies got listed so far this year, and four of them listed below the issue price. That pattern makes it harder to justify aggressive valuations and large deal sizes.

The broader dataset is also sobering. In FY26, nearly 66% of IPO listings were trading below their issue price, and ₹179,000 crore was raised through 112 mainboard and 254 SME issues. Even large listings such as Hyundai Motor India were cited as trading below issue price, reflecting cautious sentiment.

Mainboard fundraising is running behind the last two years

The pipeline still exists, but execution has slowed. Overall, there have been about 20 mainboard IPOs so far this year, with companies raising under ₹20,000 crore in the first five months of the year. That compares with over ₹27,000 crore in each of the past two years over the same period.

Deal sizes have also been smaller, according to the commentary in the article. And the market has become less forgiving for issuers targeting high valuations without clear demand from institutions.

Sebi steps in with flexibility on approvals and issue sizing

Regulatory changes have been used to provide companies more time and more flexibility. The markets regulator Sebi extended the validity of IPO approvals by six months until September 2026. Merchant bankers expect this window could be extended by another six months, based on the article.

Separately, Sebi has allowed companies to reduce IPO sizes by up to 50% without refiling a draft prospectus. This relief applies to IPOs opening on or before September 30, 2026, giving issuers more room to match deal size to demand.

SME IPOs keep coming, but gains have cooled

Even as the mainboard market pauses, activity in the SME segment remains visible. In one reported week, eight SME companies were set to launch IPOs to collectively raise around ₹440 crore. In the SME segment overall, 45 companies raised ₹2,133 crore in early 2026, showing that issuance continued even as mainboard sentiment weakened.

However, the SME market is not immune to changing risk appetite. The article notes that the SME IPO market, once seen as a place for quick gains, has cooled. Average listing gains fell to about 2.8% in early 2026, with most new listings failing to hold their issue price.

Key numbers at a glance

What is driving the split: risk-off flows, crude, and valuation resets

The article links the mainboard slowdown to a mix of geopolitical tensions, inflation concerns, and volatile equity markets. Rising crude oil prices and significant foreign portfolio investor outflows are described as contributing to a downturn and heightened volatility. These conditions reduce liquidity and make it harder for companies to command favourable valuations.

There is also a valuation recalibration underway. With several IPOs listing at discounts and post-listing performance weakening, investors have become more selective and value-sensitive, as the article states. That dynamic hits large, high-valuation offerings first, because they need deeper institutional participation to clear.

Market impact: supply overhang and a crowded equity calendar

Apart from sentiment, the article points to supply factors. Secondary market supply is estimated at around ₹400,000 crore in FY26. A heavy flow of already-listed equity sales can divert attention from new issues, even if domestic liquidity remains relatively strong.

This helps explain why the pipeline can look large on paper while the calendar stays thin. The article describes a widening gap between promoter expectations and investor appetite, prompting multiple issuers to defer offerings.

What to watch next for FY27 activity

Several signals in the article suggest IPO activity could remain subdued in FY27, despite a robust pipeline. The immediate swing factors are easing geopolitical tensions, stability in secondary markets, and more realistic IPO pricing.

The pipeline remains sizable, with 222 companies waiting for a market window and another 71 awaiting Sebi approvals. For investors, the near-term focus is likely to stay on issue pricing discipline and post-listing performance, which has been weak across a large share of FY26 listings.

Conclusion

India’s primary market has shifted from broad-based exuberance to a more selective phase. Mainboard IPOs have stalled, including a zero-IPO May 2026, while SME issuance continues but with lower average listing gains. The next inflection point depends on volatility easing and valuations resetting enough for large issuers to return, with Sebi’s extended timelines and sizing flexibility providing a limited window through September 2026.
