What Is a Mainboard IPO?

A Mainboard IPO is a public offering where a company lists directly on the main BSE or NSE exchange — not on the SME platforms.

SEBI sets stricter eligibility norms for mainboard listings. The company must have a minimum net tangible asset of ₹3 crore in each of the last 3 years, average operating profit of ₹15 crore over 3 years, and a minimum post-issue paid-up capital of ₹10 crore. These conditions filter for companies with a more established financial track record.

Retail lot sizes for mainboard issues are typically ₹14,000–₹15,000 per application. Post-listing liquidity is significantly better than SME issues, and price discovery is more efficient because of stronger institutional participation.

Turtlemint Fintech Solutions IPO

Turtlemint Fintech was founded in 2015 and operates as India's largest insurtech distribution platform. It connects insurance companies, certified advisors called PoSPs, and end customers. It also distributes mutual funds and loan products alongside insurance.

As of September 2025, Turtlemint had 603,000+ registered Digital Partners. Among comparable platforms, it held a 15.97% share of India's total PoSP advisor base — the highest in the segment.

Revenue grew from ₹419.9 crore in FY23 to ₹662.7 crore in FY25. The company is not yet profitable — FY25 net loss was ₹194.1 crore, roughly flat from FY24, which indicates burn is stabilising. IPO proceeds will fund technology salaries (₹193 crore), cloud infrastructure (₹25.6 crore), and marketing (₹39 crore).

Lead managers are ICICI Securities, JM Financial, Jefferies India, and Motilal Oswal — among the most credible names for a mainboard listing.

Big Mainboard IPOs Expected in H2 2026

H2 2026 adds significantly to the upcoming mainboard IPO 2026 India list in the second half of the year. These are the most anticipated listings — dates are not confirmed yet and depend on SEBI approvals and market conditions.

Company	Sector	Expected Issue Size	Current Status
Reliance Jio Platforms	Telecom / Digital	₹33,000–₹38,000 crore	DRHP imminent; H2 2026 or H2 FY27
Zepto	Quick Commerce	₹8,010 crore (fresh)	SEBI approved May 8, 2026
PhonePe	Fintech / Payments	~₹10,000–₹12,000 crore	SEBI approved
OYO (Prism)	Travel / Hospitality	₹6,650 crore	DRHP filed
NSE	Stock Exchange	TBA	Regulatory clearance pending

Reliance Jio's IPO could be the largest in India's history. The valuation range is ₹10.8 lakh crore to ₹14.1 lakh crore. Even at a 2.5% public float, the raise could be ₹33,000–₹38,000 crore. Management called the listing "imminent" in April 2026 but geopolitical uncertainty may push it to H2 FY27.

Zepto received SEBI's formal approval on May 8, 2026. It has filed an updated DRHP for a ₹8,010 crore fresh issue. As of March 2026, it had 47.97 million annual users, 2.33 million daily orders, and 1,139 dark stores across 66 cities. Goldman Sachs, Morgan Stanley, and JM Financial are its appointed bankers.

How to Read the Upcoming Mainboard IPO 2026 India List Before Applying

Every issue on the upcoming mainboard IPO 2026 India list looks attractive on paper. The work is in separating quality issues from overpriced ones. These are the data points that actually matter.

Parameter	Strong Signal
QIB Subscription	5x+ — institutional buyers have done the research
GMP Trend	Stable or rising across all 3 days of subscription
Anchor Investor Quality	Reputed MFs or FIIs in anchor round
Use of Proceeds	Capex/growth over full promoter OFS exit
Revenue Trend	Consistent YoY growth over 2+ years
Valuation vs Peers	Issue P/E comparable to listed sector players
Lead Manager Track Record	SEBI-registered bankers with strong past performance

QIB subscription is the most credible signal. Mutual funds, FIIs, and insurance companies only bid when they have done serious fundamental analysis. CMR Green Technologies had 270x QIB subscription — that level of institutional conviction rarely goes wrong on listing day.

Anchor investor quality matters just as much as the subscription number. A strong anchor round — with domestic MFs like SBI, HDFC, or Mirae, or global FIIs — tells you the issue has passed scrutiny at the highest level before retail investors even get a chance to bid.

Mainboard IPO Allotment — How It Works

When any issue from the upcoming mainboard IPO 2026 India list is oversubscribed in the retail category, SEBI mandates a computer-based lottery system. Each retail applicant gets either one lot or nothing — applying for more lots does not improve your chances.

The allotment date is usually T+6 from the IPO close date. Shares are credited to your Demat account on T+6 and listing happens on T+7. You can sell on listing day after the market opens at 10:00 AM.

If you do not get allotment, your blocked funds are released on the same day as allotment finalisation. For UPI-based applications, the release is automatic through your bank.

Frequently Asked Questions

1. What is the minimum investment for a mainboard IPO in 2026?

For most issues on the upcoming mainboard IPO 2026 India list, the minimum retail lot is designed so that one lot costs between ₹14,000 and ₹15,000. CMR Green Technologies required ₹14,976 for 78 shares, and Hexagon Nutrition required ₹14,985 for 333 shares. This is significantly lower than SME IPOs which can require ₹2–3 lakh per application.

2. How is QIB subscription different from retail subscription in a mainboard IPO?

QIB stands for Qualified Institutional Buyer — it includes mutual funds, FIIs, insurance companies, and banks. They get 50–75% of the issue reserved for them. Their subscription level is the strongest indicator of institutional confidence in the issue. Retail gets 10–35% of the issue and allotment is by lottery when oversubscribed.

3. Does a high GMP guarantee strong listing gains in mainboard IPOs?

No. GMP is an unofficial grey market figure and can change sharply between subscription close and listing day. CMR Green Technologies had a GMP of ₹66–₹70 during subscription — that is a strong signal, but it still needs to be read alongside QIB subscription, anchor investor quality, and market conditions on listing day.

4. When will Reliance Jio and Zepto list on the mainboard?

Zepto received SEBI approval in May 2026 and a July 2026 listing window is being discussed. Reliance Jio management confirmed the IPO is imminent in April 2026 but some reports suggest H2 FY27 is more likely given global uncertainty. Both will be mainboard listings on BSE and NSE.

5. How do I apply for a mainboard IPO in India?

You need a PAN card, a Demat account with a SEBI-registered broker, and a bank account with UPI or ASBA enabled. Go to your broker app, select the open IPO from the IPO section, enter your lot quantity and bid price, and submit. For book-built issues, always bid at the cut-off price unless you have a specific reason to bid lower. Applications are only accepted during the subscription window.
