Introduction:
IPOs (Initial Public Offerings) give investors the chance to get in on the ground floor of a company’s public journey. Whether you’re looking to diversify your portfolio or catch the next big growth story, IPOs are exciting. But here’s the thing – not all IPOs are created equal.
Before you hit the “Apply” button, there’s a choice to make:
Mainboard IPO or SME IPO?
Both come with their own advantages, trade-offs, and target investors. Pick the wrong fit, and it could throw off your entire investment game. So let’s dive deep and figure out what really suits you.
What is a Mainboard IPO?
A Mainboard IPO is issued by well-established companies that meet stricter eligibility criteria set by SEBI. These companies usually have a solid track record, consistent profits, and a sizable market presence. They list on the main platforms of NSE or BSE, and their IPOs attract a broad investor base – retail, HNIs, and institutional investors alike.
Typical Features:
- Post-issue capital: Over ₹10 crores
- Regulated more strictly under SEBI’s detailed disclosure norms
- Higher liquidity due to wider participation
- Audited financials and full compliance with corporate governance
- Institutional confidence, often backed by marquee investors
Who invests?
These IPOs typically appeal to retail investors who want dependable, stable returns and also to institutions who want long-term holdings in blue-chip potential companies.
What is an SME IPO?
SME IPOs (Small and Medium Enterprise IPOs) are launched by emerging businesses still in early or mid-growth stages. These companies are smaller in scale and capital, and they list on dedicated platforms like NSE Emerge or BSE SME.
These IPOs are specifically designed to help small businesses raise capital without the heavy cost of Mainboard listing. But that also means they come with their own challenges – limited liquidity, lower visibility, and fewer regulatory obligations.
Typical Features:
- Post-issue capital: ₹1 crore to ₹10 crores
- Relaxed eligibility norms, easier for new businesses to enter
- Lower compliance and listing costs
- Larger lot sizes with higher minimum investment
- Limited trading activity compared to Mainboard listings
Who invests?
Mostly experienced investors or HNIs who understand risk and are actively looking for high-reward opportunities. These investors are usually comfortable doing deep-dive research on smaller businesses.

Which Path Should You Take?
The answer depends entirely on your investor profile.
You should consider a Mainboard IPO if:
- You are a risk-averse or conservative investor. You prioritize capital safety over exceptional returns.
- You are new to the stock market. Mainboard IPOs are a more stable and forgiving entry point.
- You prefer liquidity. You want the flexibility to enter and exit your investment easily.
- You are looking for steady, long-term wealth creation from established market leaders.
You might consider an SME IPO if:
- You have a high-risk appetite. You accept the risk of a complete loss in pursuit of higher returns.
- You are an experienced investor. You know how to analyze businesses independently without relying on analyst reports.
- You have surplus capital. SME IPOs require a larger upfront investment – only use money you can afford to lose.
- You are hunting for the next multi-bagger and are willing to wait patiently for a growth story to unfold.
Risks and Rewards
Mainboard IPOs are typically considered more secure because of the company’s scale, proven history, and tighter regulatory checks. But they might already be fairly priced at launch, limiting short-term upside.
SME IPOs come with greater risk – they’re often young, less predictable businesses with low liquidity and limited market visibility. But that also means potential for explosive returns, if you back the right one.
Final Thoughts
There’s no one-size-fits-all answer. What matters is knowing who you are as an investor. Are you in it for growth? Security? Short-term flips? Long-term wealth building?
Both Mainboard and SME IPOs can fit into your investment strategy – but only when chosen with clarity and understanding.

FAQs
How is a Mainboard IPO different from an SME IPO?
The key differences lie in risk level and minimum investment.
- Mainboard IPOs are issued by larger, stable companies and involve lower risk. The entry amount is usually around ₹15,000.
- SME IPOs are offered by smaller, less established businesses. They carry higher risk and require a larger minimum investment – often over ₹1,00,000.
Are SME IPOs riskier than Mainboard IPOs?
Yes. SME IPOs are generally riskier because they involve early-stage businesses, lower liquidity, and less regulatory oversight. That said, they also have the potential for higher returns if the company scales successfully.
Who should invest in a Mainboard IPO?
Mainboard IPOs are ideal for conservative or first-time investors who value stability, strong compliance, and better liquidity. They offer a safer entry point into the stock market.
Who should consider investing in SME IPOs?
SME IPOs are better suited for experienced investors with a high-risk appetite and the ability to do their own analysis. They should also have surplus capital, as the investment threshold is significantly higher.
I can’t sell just one share of an SME IPO stock after it lists. Why?
SME IPO stocks trade in fixed lot sizes. If the lot size is 1,000 shares, you can only buy or sell in multiples of 1,000. Individual share trading isn’t allowed, which limits flexibility and contributes to lower liquidity compared to Mainboard IPOs, where you can trade even one share.
Why is the minimum investment for SME IPOs so high?
It’s a regulatory safeguard. The high entry cost (typically ₹1 lakh or more) ensures that only financially capable and informed investors participate. This protects smaller, retail investors from taking on risks they might not fully understand or afford.
What is a “Market Maker” and why are they important for SME IPOs?
A Market Maker is a stockbroker appointed by the company to provide continuous buy and sell quotes for its stock. Their role is crucial in maintaining liquidity in the SME market, where trading volumes can be low. By always being available to trade, they help ensure price stability and smoother transactions in the early months after listing.
How can I evaluate whether an IPO is worth investing in?
Start by reviewing the company’s DRHP (Draft Red Herring Prospectus). Look into its financials, industry potential, promoter background, and peer comparison. Also, track GMP (Grey Market Premium) trends. IPO platforms like IPOCornerr offer tools and insights to help simplify this research.
Can SME IPOs deliver better returns than Mainboard IPOs?
Potentially, yes. Some SME IPOs have turned into multibagger investments, but many underperform or fail to scale. It’s high risk, high reward – success depends on your ability to identify quality businesses early and hold for the long term.
