Market Maker in SME IPO: Why Emerge Stocks Have One and What Happens When It Leaves

Buy a small-company stock on NSE Emerge and there is usually someone on the other side of the screen whose job is to trade with you. That someone is the market maker. A market maker in an SME IPO is a stockbroker the issuer appoints to keep buying and selling the shares after listing, so that a thinly held small company does not turn into a stock you simply cannot exit. It is one of the biggest differences between the SME platform and the main board, and right now SEBI is proposing to scrap it.

We’ll go through what the rule actually requires, what the market maker has to do on a normal trading day, how much it costs issuers, and what changes for you if the SEBI proposal goes through. The worked examples use made-up numbers, and we say so each time.

What a Market Maker in an SME IPO Is Required to Do Under SEBI Rules

The legal hook is Regulation 261 of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, the rulebook for public issues. SEBI’s own consultation paper of October 14, 2026 on SME IPOs reproduces the existing text in full, and it reads like this, in plain words:

• The lead manager has to ensure compulsory market making through stockbrokers of the SME exchange, appointed by the issuer, for a minimum of three years from listing (or from migration down from the main board).
• The market maker’s inventory on the date of allotment must be at least 5% of the shares proposed to be listed on the SME exchange.
• The market maker or issuer can tie up with nominated investors who receive or deliver shares in the market-making process, with the SME exchange’s prior approval.
• The issuer must disclose the market-making arrangement in the offer document.
• If a shareholder’s holding is worth less than the minimum contract size on the exchange, the market maker has to buy the whole holding in one lot. It cannot sell to anyone in less than the minimum contract size, though.
• The market maker cannot buy from promoters, the promoter group, or anyone who bought shares from them, during the compulsory period. Promoter shares are also not eligible to be offered to the market maker; holdings that are not locked in can trade only with the SME exchange’s prior permission.
• The lead manager responsible for market making may sit on the issuer’s board, if the two agree.

Two things jump out. The three-year clock is long, much longer than the excitement of listing day. And the promoter restrictions exist for an obvious reason: without them, the market maker could become a convenient exit door for insiders.

A Normal Day for an Emerge Market Maker

The regulation sets up the obligation. The exchange sets the daily mechanics. NSE’s page on market maker roles and responsibilities lists them:

• Provide a two-way quote (a buy price and a sell price) for 75% of the time in a day.
• Minimum depth of the quote is ₹1,00,000. Investors whose holding in that stock is worth less than ₹1,00,000 can offer the whole holding to the market maker in one lot, with a declaration to the selling broker.
• The market maker must guarantee execution at the price and quantity it quotes.
• No more than five market makers per stock, and they can compete with each other on quotes.
• Quoting starts from the day of listing and runs for three years.

NSE’s Market Makers on Emerge page adds that the quotes have to be within the stipulated bid-offer spread, and that the market maker is also expected to watch trading in the stock and report anomalies to the exchange. Any existing NSE member can apply to be one, provided it meets the exchange’s criteria and registers.

You can actually spot the market maker on screen. According to NSE’s description of the Emerge trading system, the SME order book in the normal market shows five-deep market depth, and market maker quotes are flagged with a “#” so you can tell them apart from anonymous orders. Some SME stocks trade in call auction sessions instead of the continuous market; there the market maker has to give two-way quotes of at least one trading lot in each session, and market maker orders do not match against each other. The issuer picks normal or call auction trading in the offer document and can switch later with exchange approval and one month’s notice to the market.

A market maker guarantees that someone will quote. It does not guarantee the price you will like.

Worked Example 1: How Big Is the Inventory?

Illustrative numbers, not a real company. Say an SME issuer is listing 80,00,000 shares and the issue price is ₹120.

• Minimum market maker inventory at allotment: 5% of 80,00,000 = 4,00,000 shares.
• Value at the issue price: 4,00,000 × ₹120 = ₹4,80,00,000, or ₹4.8 crore.

That stock is what lets the market maker sell to you on day one. When buying pressure is heavy and the inventory gets used up, the sell side of its quote becomes harder to sustain. When selling pressure is heavy, the market maker keeps absorbing shares and its inventory grows. Either way, 5% is a cushion, not a bottomless tank. On a stock where lots of allottees want out on the same day, one broker’s two-way quote can’t soak up all of it.

Worked Example 2: The Small-Holding Exit

Illustrative numbers. Suppose an Emerge stock trades in lots of 1,200 shares, and you are holding 900 shares, an odd quantity left over after a corporate action. The stock is at ₹95.

• Value of your holding: 900 × ₹95 = ₹85,500.
• That is below the ₹1,00,000 threshold on NSE’s market maker page, and below one trading lot, so you cannot sell it in the normal lot-based market.
• Under Regulation 261 and NSE’s rules, you can offer all 900 shares to the market maker in one go, with a declaration through your broker.

This is one of the quieter benefits of the system. Odd quantities are a real headache on the SME platform because trading happens in big lots. SEBI’s paper says that, on average, about 5% of unique PAN-based shareholders held an odd lot that could not be fully traded through the regular market, which is part of why it wants one-share trading lots.

Worked Example 3: What the Spread Costs You

Illustrative quote, not an exchange limit. A market maker shows a bid of ₹96 and an offer of ₹100 on an SME stock.

• Spread: ₹100 − ₹96 = ₹4, which is about 4.1% of the ₹98 midpoint.
• If you bought one lot of 1,200 shares at ₹100 and the quote didn’t move, selling straight back at ₹96 would cost you 1,200 × ₹4 = ₹4,800, or 4% of the ₹1,20,000 you put in, before brokerage and taxes.

So the market maker solves “can I exit?” more than “can I exit cheaply?”. The exchange caps how wide the quote can be, but a stock with a wide allowed spread and little genuine interest can still be expensive to get in and out of. Check the live bid and offer, and how much is shown at each, before you assume an SME stock is liquid.

How Much Market Making Costs the Issuer

Market makers are paid. SEBI’s consultation paper, working from prospectus disclosures, puts average market-making fees at 1.25% of total issue expenses for NSE SME IPOs in FY 2024-25 and 1.58% in FY 2025-26. For BSE SME IPOs, the figures were 4.20% and 2.60%. On top of fees, there is the cost of carrying the 5% inventory.

Note what those percentages measure: the share of an issue’s total expenses that went to market making, not a percentage of the money raised. Underwriting was the much bigger slice, which we covered in our report on the SEBI SME IPO proposal.

Why SEBI Wants to Drop Compulsory Market Making

The regulator’s case is about how little the market makers actually trade. The same paper says that from August 2025 to July 2026, market-maker turnover was 0-10% of total turnover in 361 NSE SME stocks and 268 BSE SME stocks. In other words, in a large number of SME scrips, most trading was already happening between ordinary buyers and sellers.

The working group therefore recommended removing compulsory market making entirely, including the inventory requirement and the related mandatory arrangements, and SEBI’s Primary Market Advisory Committee (PMAC) proposed accepting this. The draft simply marks Regulation 261 as “Omitted”. The argument ties into another proposal in the same paper: SME shares would trade in lots of one share, so investors could buy and sell small quantities themselves and liquidity could build from real demand rather than from an obligation placed on one broker.

One-share lots make it easier to place a sell order. They don’t create a buyer for it.

What Happens to Stocks That Already Have a Market Maker

This is the part existing SME shareholders should read carefully. The paper proposes that SEBI, in consultation with the exchanges, would issue a separate circular after the new framework is notified, rescinding the current SME trading-lot circular. From that circular’s date:

• the one-share trading lot would apply to all SME-listed securities, and
• the existing market-making framework would stop applying to all SME-listed issuers, regardless of when they listed or how much of the three years has already run.

Companies that list after the new rules are notified but before that circular would still carry market makers until the circular date. SEBI’s paper gives a hypothetical timeline to show the sequence: if the framework were notified on December 31, 2026 and the rescinding circular came on February 15, 2027, every SME issuer’s market-making arrangement would end on February 15, 2027, and issuers listing from that date would never have one. Those dates are SEBI’s illustration, not a schedule. As of now this is a consultation paper, and nothing has changed.

What This Means If You Hold or Bid for SME Stocks

A few practical takeaways for anyone looking at the SME segment:

1. Read the market-making section of the offer document. It names the market maker and the arrangement. The issuer has to disclose it under the current rules.
2. Look for the “#” quote in the order book. If the only depth on screen is the market maker, the stock’s liquidity is borrowed, not earned.
3. Don’t treat the three-year window as a promise. If SEBI’s proposal is adopted, market making could end for every SME stock on a single date, mid-way through many companies’ three years.
4. Watch genuine volumes. SEBI’s own data says market makers were a small share of turnover in hundreds of SME scrips. Stocks that already trade well without them may not notice much difference. Stocks that lean on the market maker could see wider spreads and thinner books.
5. Check where the company is heading. Some SME companies later migrate to the main board, which changes how the stock trades. Our explainer on SME IPO migration to the main board covers the NSE Emerge rules.

The Bottom Line on SME Market Makers

Under the current rules, the market maker is the SME platform’s safety rail: a broker obliged to quote both ways for three years, carrying at least 5% of the listed shares, and ready to buy out small odd holdings. SEBI now argues the rail is costly and mostly unused, and wants one-share lots to do the job instead. Whether that works will show up stock by stock. For investors, the habit to build is the same either way: judge an SME stock’s liquidity by who else is trading it, not by who is required to.
