India has two IPO routes, and they are not simply large and small versions of the same thing.
Mainboard
The main platforms of NSE and BSE. Companies must meet substantial eligibility requirements covering size, track record and net worth, with stringent disclosure obligations both at issue and continuously after listing.
These are the issues you see covered in the news.
SME platforms
NSE Emerge and BSE SME were created so smaller companies could raise public capital without meeting full mainboard requirements. Eligibility thresholds are lower, and the issue process is lighter in several respects.
Lower thresholds are the entire point of the platform — and also the entire reason it carries more risk.
The differences that actually matter
| Mainboard | SME | |
|---|---|---|
| Company size | Substantially larger | Small |
| Eligibility | Stringent | Relaxed |
| Minimum application | About ₹10,000–₹15,000 | Minimum 2 lots, above ₹2 lakh |
| Cut-off price option | Available to retail | Discontinued from 1 July 2025 |
| Downward bid revision | Generally permitted | Not permitted from 1 July 2025 |
| Trading | Individual shares | In fixed lots |
| Liquidity | Generally good | Often very poor |
| Analyst coverage | Wide | Usually none |
| Disclosure frequency | Quarterly | Lighter regime |
The three risks people underestimate
1. Liquidity. This is the big one. SME shares trade in lots, volumes can be extremely thin, and spreads are wide. It is entirely possible to be unable to sell a meaningful quantity at anything close to the quoted price. The quoted price of an SME share you cannot sell is a number on a screen, not money.
2. Information. No analyst coverage, limited media scrutiny, fewer disclosures, and often a short operating history. You are relying almost entirely on the offer document and on your own work.
3. Concentration and governance. Small companies are often dependent on a handful of customers, a single facility, or one individual. Governance standards vary widely, and there have been cases of manipulation in the segment. Exchanges and SEBI have tightened rules in response — which itself tells you the problem was real.
Why the rules changed in 2025
From 1 July 2025, NSE and BSE implemented tighter SME bidding rules:
- Minimum application of two lots, with an application value above ₹2 lakh, for individual investors
- Cut-off price option removed across all categories — an explicit bid price is required
- No downward revision or cancellation of bids once placed
- Defined limits on employee bids and reserved categories
- Tighter bidding-day timings, with the UPI mandate window extending only a short period past the bidding close
The intent is to keep the segment for investors making a deliberate, sized commitment rather than a speculative flutter, and to reduce bids placed purely to inflate subscription numbers and then withdrawn.
Migration to the mainboard
An SME company that grows and meets mainboard eligibility can migrate to the main platform. This is the intended path, and migration usually improves liquidity and coverage. It is a genuine positive when it happens — and most SME companies do not get there.
If you are still considering one
- Read the offer document in full, not the summary. There is no analyst to do it for you.
- Check the promoter's background and any pledged holdings carefully.
- Look at how existing listed SME shares in the same sector actually trade — daily traded value, not price.
- Size the position as money you can afford to have locked up or lost, because exit may be slow.
- Understand that lot-based trading means you cannot trim a position in small pieces.
Key takeaways
- SME platforms have relaxed eligibility and lighter disclosure, which is both their purpose and their risk.
- From 1 July 2025, SME applications require at least two lots and a value above ₹2 lakh.
- The cut-off price option and downward bid revision are no longer available in SME issues.
- Thin liquidity is the most underestimated risk — exiting can be difficult at any price.
- SME headlines show the best outcomes; the failures are far less visible.
