Six Mainboard IPOs Open on Same Day for First Time in Three Decades as India’s Primary Market Hits New Milestone

India's primary market reached a rare milestone on September 9, 2026, as six mainboard initial public offerings opened for subscription on the same day for the first time in three decades, with the companies collectively seeking to raise approximately ₹4,509.68 crore.

The six companies entering the market simultaneously are Rentomojo, Karamtara Engineering, Manipal Payment & Identity Solutions, Asset Reconstruction Company (India), LCC Projects and Steamhouse India.

Historical data indicates that the last time exactly six IPOs opened for subscription on a single day was:

October 14, 1996.

That makes September 9 one of the most unusual IPO opening days in India's modern capital-market history.

The six offerings also span substantially different industries, ranging from furniture rental and asset reconstruction to engineering, payments, infrastructure and industrial utilities.

Their simultaneous launch highlights the sharp acceleration in India's IPO pipeline after primary-market activity was disrupted earlier in 2026 by global geopolitical uncertainty.

Six Mainboard IPOs Open Together on September 9

The six IPOs opening for subscription are:

  • Rentomojo — ₹1,255.57 crore

  • Karamtara Engineering — ₹875 crore

  • Manipal Payment & Identity Solutions — ₹805 crore

  • Asset Reconstruction Company (India), or ARCIL — ₹732.97 crore

  • LCC Projects — ₹427.14 crore

  • Steamhouse India — ₹414 crore

Together, the six offerings are targeting approximately:

₹4,509.68 crore.

All six issues are scheduled to remain open for subscription until:

September 11, 2026.

Last Six-IPO Opening Day Was in October 1996

According to historical primary-market data, the last time exactly six IPOs opened on the same day was:

October 14, 1996.

The six companies that entered the market that day were Cozy Enterprises, Hind Securities & Credits, Kanugo Lease & Investment, RCS Exports, Sona Processors (India) and XO Tronic.

Collectively, those companies sought to raise only:

₹21.58 crore.

The comparison illustrates how dramatically India's equity capital markets have expanded over the past three decades.

₹4,509 Crore Today Versus ₹21.58 Crore in 1996

The difference in fundraising scale is striking.

The six IPOs opening in September 2026 are seeking:

more than 200 times

the capital targeted by the six companies that launched together in October 1996.

India's economy, corporate sector and equity markets have all expanded substantially since then.

The investor base has also broadened through:

demat accounts,

online brokerages,

mutual funds,

institutional investors,

and digital IPO applications.

The result is a primary market capable of absorbing multi-billion-rupee offerings at a frequency that would have been difficult three decades ago.

Seven IPOs Had Opened Together Later in 1996

The September 9 milestone requires one historical distinction.

It is the first time in 30 years that exactly six IPOs have opened on the same day.

It is not the largest number of IPOs ever launched simultaneously.

On:

October 28, 1996,

seven public offerings opened together.

The 1995–96 period also saw several exceptionally crowded periods in India's primary market.

The significance of September 9, 2026 therefore lies in the return of six simultaneous mainboard launches after three decades.

Rentomojo Is Largest IPO in the Group

The largest of the six offerings is:

Rentomojo.

The furniture and appliance rental platform is seeking approximately:

₹1,255.57 crore.

Its IPO comprises:

₹150 crore of fresh shares

and:

₹1,105.57 crore through an offer for sale.

The price band has been fixed at:

₹384 to ₹404 per share.

The structure means the majority of the proceeds from the overall transaction will go to selling shareholders rather than directly to the company.

Rentomojo Brings Consumer Subscription Model to Market

Rentomojo operates a rental platform allowing consumers to access products such as:

furniture,

appliances,

and other household items

through subscription-style arrangements.

Its IPO gives public-market investors exposure to a relatively unusual consumer business model.

The company is also significant because it could establish one of the first public-market valuation benchmarks for India's organised furniture-rental industry.

Rentomojo IPO Already Attracts Strong Demand

Rentomojo's IPO became fully subscribed on its first day of bidding.

The issue received bids for more shares than were available for subscription, with demand supported by both:

retail investors

and:

non-institutional investors.

Its early subscription performance provides an important test of whether investors remain willing to fund growth-oriented consumer platforms even during a crowded IPO week.

Karamtara Engineering Seeks ₹875 Crore

The second-largest offering opening on September 9 is:

Karamtara Engineering.

The company is seeking:

₹875 crore.

The IPO consists of:

₹675 crore in fresh equity

and:

₹200 crore through an offer for sale.

Its price band is:

₹241 to ₹254 per share.

The relatively large fresh-issue component means a substantial portion of the funds raised will flow directly into the company.

Engineering IPO Adds Industrial Exposure

Karamtara Engineering gives investors exposure to a different part of India's economy from Rentomojo.

The company operates within the engineering and infrastructure ecosystem.

Industrial and infrastructure-linked businesses have attracted growing investor attention as India increases expenditure across:

power,

renewable energy,

transmission,

manufacturing,

and physical infrastructure.

This sector diversity is one feature of the September 9 IPO slate.

Manipal Payment & Identity Solutions Seeks ₹805 Crore

Manipal Payment & Identity Solutions is seeking approximately:

₹805 crore.

Its issue includes:

₹320 crore of fresh capital

and:

₹485 crore through an offer for sale.

The price band has been set at:

₹322 to ₹339 per share.

The company operates in technology-enabled payment and identity solutions, providing another distinct business category within the six-IPO group.

Payments and Identity Technology Attract Investor Interest

India's payments infrastructure has expanded rapidly over the past decade.

Growth in:

digital transactions,

banking technology,

identity systems,

and financial inclusion

has created opportunities for companies providing specialised technology and infrastructure to banks, governments and other institutions.

Manipal Payment's IPO allows public investors to evaluate a business exposed to this broader digitisation trend.

ARCIL IPO Is Entirely an Offer for Sale

Asset Reconstruction Company (India), commonly known as ARCIL, is seeking:

₹732.97 crore.

Unlike several of the other offerings, ARCIL's IPO is:

entirely an offer for sale.

Its price band is:

₹132 to ₹139 per share.

Because there is no fresh issue component, the company itself will not receive proceeds from the IPO.

The transaction instead provides liquidity to existing shareholders selling their holdings.

ARCIL Brings Asset-Reconstruction Business to Public Markets

ARCIL operates in India's:

asset reconstruction

industry.

Asset reconstruction companies acquire and resolve stressed financial assets, making them an important part of the banking and credit ecosystem.

The business differs significantly from the consumer, engineering and infrastructure companies launching alongside it.

This gives investors a diverse set of business models to evaluate despite all six issues arriving simultaneously.

LCC Projects Plans ₹427.14 Crore IPO

LCC Projects is seeking approximately:

₹427.14 crore.

The offering comprises:

₹258 crore in fresh capital

and:

₹169.14 crore through an offer for sale.

The company has set its price band at:

₹139 to ₹146 per share.

LCC Projects operates in the infrastructure sector, adding another capital-intensive business to the week's IPO calendar.

Infrastructure Companies Continue Tapping Equity Markets

India's infrastructure investment cycle is creating significant funding requirements.

Companies need capital for:

equipment,

working capital,

project execution,

and balance-sheet strengthening.

Public equity can provide an alternative to relying entirely on debt.

The strong IPO pipeline among engineering and infrastructure companies therefore reflects both investor appetite and substantial corporate capital requirements.

Steamhouse India Seeks ₹414 Crore

The sixth company opening its IPO is:

Steamhouse India.

The company plans to raise approximately:

₹414 crore.

Its IPO includes:

₹353 crore of fresh equity

and:

₹61 crore through an offer for sale.

The price band is:

₹77 to ₹81 per share.

The fresh issue represents the majority of the transaction, meaning most of the IPO proceeds are intended to enter the company rather than being paid to selling shareholders.

Six IPOs Span Very Different Businesses

One reason the simultaneous launches are particularly notable is their diversity.

Investors are being asked to evaluate companies across:

consumer rentals,

engineering,

payments technology,

asset reconstruction,

infrastructure,

and industrial services.

This differs from IPO waves concentrated heavily in one sector.

The diversity could help distribute investor demand, but it also creates a substantial research burden for investors considering multiple offerings at once.

All Six Issues Close on September 11

The six IPOs share the same subscription window.

They opened on:

September 9

and are scheduled to close on:

September 11.

Tentative allotments are expected around:

September 15,

with share credits and refunds expected subsequently.

Listings are broadly scheduled for:

September 17, 2026,

subject to completion of the standard IPO process.

Ten IPOs Are Simultaneously Available for Subscription

The primary market is even more crowded than the six new openings suggest.

On September 9, investors have:

10 IPOs

available for subscription at different stages.

While six opened during the day, three previously launched offerings entered their second day of bidding.

These include:

Kanohar Electricals,

Prasol Chemicals,

and Glass Wall Systems (India).

Another IPO, Pranav Constructions, entered its final subscription day.

Ten Issues Seek More Than ₹7,288 Crore

Taken together, the 10 IPOs available for subscription on September 9 are seeking approximately:

₹7,288 crore.

That creates significant competition for investor capital.

Institutional investors need to determine how much money to allocate across multiple offerings.

Retail investors face a similar decision, particularly when capital may remain blocked during the IPO application and allotment process.

The crowded calendar can therefore influence subscription patterns even when overall market liquidity remains strong.

Twelve Mainboard IPOs Are Scheduled During the Week

The September 9 rush forms part of an even larger primary-market wave.

As many as:

12 mainboard IPOs

are scheduled to open between September 7 and September 11.

Together, these companies are targeting approximately:

₹7,180 crore

through their offerings.

The concentrated calendar makes the week one of the busiest stretches for India's primary market in 2026.

September IPO Pipeline Is Even Larger

The rush is unlikely to end with the current group.

Investment bankers expect September to remain an exceptionally active month.

Companies across:

automotive technology,

financial markets,

consumer businesses,

manufacturing,

and technology

have been preparing offerings.

The month could therefore become one of the most significant IPO periods of the year by total fundraising.

Companies Are Rushing to Use Available Market Window

Several factors are contributing to the concentrated calendar.

One is:

regulatory timing.

Companies that have received regulatory approval for IPOs cannot delay their offerings indefinitely.

Approvals and financial disclosures operate within defined validity periods.

Some issuers are therefore moving to market before their available regulatory window expires.

This can result in multiple companies launching within the same period.

Strong August IPO Performance Encouraged Issuers

The second major factor is:

recent IPO performance.

August was a strong month for India's primary market.

Several offerings attracted substantial subscriptions and delivered positive listing performances.

When recently listed companies perform well, private companies become more comfortable launching their own offerings.

Bankers and shareholders can also become more confident that sufficient investor demand exists.

62 Mainboard Companies Raised More Than ₹73,600 Crore

By the end of August 2026:

62 mainboard companies

had raised approximately:

₹73,669 crore

through IPOs during the year.

That represents substantial equity fundraising despite the disruption seen earlier in 2026.

August alone was particularly active, with more than 20 companies accessing the mainboard market.

The September pipeline suggests annual fundraising could increase considerably during the remainder of the year.

India Remains One of World's Busiest IPO Markets

India has become one of the world's most active IPO markets by number of transactions.

Including a broader universe of offerings, around:

165 IPOs

had raised approximately:

$8.61 billion

by late August.

The volume reflects India's unusually deep pipeline of companies seeking public capital across both:

mainboard

and:

smaller-company markets.

This has made India an increasingly important market for global equity-capital activity.

Earlier Geopolitical Uncertainty Slowed 2026 IPO Activity

The year did not begin with the same momentum.

Global geopolitical tensions and market volatility initially made companies more cautious about launching public offerings.

When equity markets become volatile, issuers risk:

weak subscriptions,

lower valuations,

or poor listing performance.

Many companies therefore postpone IPOs until market conditions stabilise.

The current September rush partly reflects offerings that accumulated during the slower period.

Improved Risk Appetite Reopened IPO Window

As investor sentiment improved, the primary-market window reopened.

Companies that had already completed much of their regulatory preparation were able to move quickly.

This has created a compressed calendar.

Rather than IPO activity being evenly distributed across the year, several issuers are now attempting to raise capital simultaneously.

Retail Participation Remains Important

Retail investors remain a major component of India's IPO ecosystem.

Digital investing platforms and UPI-based IPO applications have made participation substantially easier.

An investor can now apply to an IPO through:

online brokers,

banking platforms,

or other digital channels

without the paper-based process that characterised the market three decades ago.

This technological transformation has dramatically increased accessibility.

Demat Account Growth Has Expanded Investor Base

India's rapidly growing demat-account population has also enlarged the potential IPO investor pool.

Millions of new investors entered equity markets during and after the pandemic period.

Even if only a fraction participate actively in IPOs, the resulting pool of capital can be substantial.

This structural expansion helps explain how the market can absorb multiple large offerings simultaneously.

Mutual Funds Have Added Institutional Depth

India's domestic institutional investor base has also become significantly stronger.

Mutual funds receive large recurring inflows through:

systematic investment plans

and other investment products.

Insurance companies and other domestic institutions provide additional capital.

This reduces India's dependence on foreign institutional investors compared with earlier periods.

A deeper domestic capital base can make the IPO market more resilient.

Foreign Investors Remain Important for Large Offerings

Foreign institutional investors nevertheless remain important, particularly for:

large IPOs

and:

qualified institutional buyer allocations.

Global funds assess Indian offerings against investment opportunities across other emerging and developed markets.

Strong domestic economic growth and corporate earnings can make Indian IPOs attractive.

However, valuation remains critical.

Global investors can avoid offerings they believe are priced too aggressively.

Crowded Calendar Could Dilute Subscription Demand

The six-IPO milestone also creates a risk.

Investor capital is:

finite.

When several IPOs open simultaneously, each company must compete for attention and money.

An investor who might have placed a large application into one IPO could divide that capital among several issues.

This can reduce subscription multiples even when the overall market remains healthy.

Investors Are Likely to Become More Selective

A crowded market tends to increase:

selection discipline.

When only one major IPO is available, investors may focus heavily on that company.

When six open together, comparisons become unavoidable.

Investors can evaluate:

valuation,

growth,

profitability,

management quality,

debt,

use of proceeds,

and competitive position

across multiple alternatives.

That can benefit stronger issuers while creating challenges for aggressively priced offerings.

Listing Gains Cannot Be Assumed

Strong recent IPO performance has increased investor interest, but listing gains are never guaranteed.

The price of a newly listed company depends on:

subscription demand,

market conditions,

valuation,

institutional positioning,

and investor sentiment.

A heavily subscribed IPO can still disappoint after listing if expectations become excessive.

The number of IPOs entering the market therefore shouldn't be interpreted automatically as evidence that every issue offers attractive returns.

Fresh Issue and OFS Structures Matter

The six offerings also differ significantly in how the proceeds are structured.

A:

fresh issue

provides new capital to the company.

An:

offer for sale

allows existing shareholders to sell shares.

This distinction matters when evaluating how an IPO changes a company's financial position.

For example, ARCIL's offering is entirely an OFS, while Steamhouse India and Karamtara Engineering contain substantial fresh-issue components.

Fresh Capital Can Fund Growth or Reduce Debt

Companies can use fresh IPO proceeds for purposes such as:

capacity expansion,

debt repayment,

working capital,

technology investment,

and general corporate requirements.

If deployed effectively, the capital can increase future earnings.

Investors therefore need to examine not only how much money an IPO raises but also:

where the money is going.

A large IPO doesn't necessarily mean the company itself receives a large amount of capital.

OFS Provides Liquidity to Existing Shareholders

Offer-for-sale components serve a different purpose.

The proceeds go to:

promoters,

venture-capital investors,

private-equity funds,

or other existing shareholders

selling their stakes.

An OFS can be entirely legitimate and is common in IPOs.

However, investors need to understand whether the transaction primarily finances corporate growth or provides an exit to existing owners.

IPO Market Is Becoming a Major Exit Route

The current activity also demonstrates how India's public markets have become an increasingly important exit route for:

private equity

and:

venture capital.

Private investors often hold companies for several years before seeking liquidity.

An IPO allows them to sell part of their holdings while potentially retaining exposure to future growth.

A deep public market therefore strengthens the entire private-capital ecosystem.

More Successful IPOs Can Encourage Startup Listings

The strength of India's IPO market is also important for startups.

For years, many Indian technology startups depended heavily on:

private venture capital.

A functioning IPO market gives mature startups another route to raise capital and provide investor liquidity.

Rentomojo's offering is particularly relevant in this context because it brings a digitally enabled consumer business into the public market.

Public Markets Demand Greater Financial Discipline

Listing also changes how companies operate.

Public companies must comply with more extensive requirements around:

financial reporting,

corporate governance,

disclosures,

and shareholder communication.

Quarterly performance becomes visible to investors.

This creates greater scrutiny than many companies experience while privately held.

The expanding IPO market therefore also represents a transition toward greater institutionalisation among Indian businesses.

September Could Test Depth of Investor Liquidity

The concentrated IPO calendar will provide a useful test of India's capital-market depth.

If multiple offerings can achieve:

healthy institutional demand,

strong retail participation,

and stable post-listing performance,

it would demonstrate the market's ability to absorb substantial new equity.

If subscription demand weakens sharply across later offerings, it could indicate that the pipeline has temporarily exceeded investor capacity.

Secondary Market Conditions Still Matter

IPO activity does not operate independently of the broader stock market.

Indian benchmark indices have recently faced pressure from factors including:

higher crude-oil prices,

global geopolitical uncertainty,

and foreign-investor flows.

If secondary markets weaken significantly, IPO sentiment can change quickly.

Companies currently accessing the market are therefore using an available fundraising window that cannot be assumed to remain open indefinitely.

Strong IPO Supply Can Temporarily Absorb Market Liquidity

A large IPO calendar can also affect secondary-market liquidity.

Investors may sell existing shares or keep cash available to fund IPO applications.

Institutional investors likewise need to allocate capital between:

existing listed companies

and:

new offerings.

During particularly crowded weeks, this can temporarily divert some money toward the primary market.

1996 Comparison Shows Transformation of Indian Capital Markets

The contrast with 1996 provides perhaps the clearest illustration of how far India's capital markets have developed.

Six IPOs opening together three decades ago sought only:

₹21.58 crore.

Six companies opening together today are seeking:

₹4,509.68 crore.

The increase reflects more than inflation.

It demonstrates the growth of:

Indian corporations,

market capitalisation,

household financial participation,

institutional investment,

and capital-market infrastructure.

Digital Infrastructure Has Changed IPO Participation

The mechanics of applying for an IPO have also transformed.

In the 1990s, applications depended heavily on:

physical forms,

cheques,

and manual processing.

Today, investors can apply digitally using:

demat accounts,

ASBA,

UPI,

and online brokerage platforms.

This has reduced friction and enabled far greater numbers of investors to participate simultaneously.

India’s Primary Market Is Entering a New Scale

The September 9 milestone is therefore not merely about six companies choosing the same date.

It reflects the scale India’s primary market has reached.

A single day can now bring together more than:

₹4,500 crore

of new equity offerings across six unrelated businesses while several other IPOs remain open simultaneously.

That would have represented an extraordinary amount of market activity in earlier decades.

It is increasingly becoming possible within India's modern capital-market infrastructure.

Conclusion

India's primary market marked a rare milestone on September 9, 2026, as six mainboard IPOs opened for subscription on the same day for the first time in three decades.

The six companies — Rentomojo, Karamtara Engineering, Manipal Payment & Identity Solutions, Asset Reconstruction Company (India), LCC Projects and Steamhouse India — are collectively seeking approximately ₹4,509.68 crore.

The last time exactly six IPOs opened together was October 14, 1996, when the six offerings sought only ₹21.58 crore combined. The comparison highlights the extraordinary expansion of India's equity-capital markets over the intervening 30 years.

The September 9 launches are also part of a broader IPO surge, with 10 issues simultaneously available for subscription at different stages during the day and 12 mainboard IPOs scheduled to open during the week.

Strong recent subscriptions, improved listing performance, abundant domestic liquidity and regulatory timelines are encouraging companies to use the current fundraising window.

However, the crowded calendar also means investors have more alternatives and are likely to become increasingly selective about valuation, business quality, use of proceeds and long-term earnings potential.

The milestone therefore represents both the growing depth of India's primary market and an important test of how much new equity investors can absorb as the country's 2026 IPO pipeline accelerates.
