The Indian primary market witnessed a historic day on September 9, 2026, with six mainboard IPOs opening simultaneously—a feat not seen since 1996. Companies including RentoMojo and ARCIL are collectively targeting ₹4,510 crore. Investors should monitor liquidity strain and valuation risks as capital shifts from a stagnant secondary market to these new offerings.
September 9, 2026, marks a historic day for the Indian primary market as six mainboard initial public offerings (IPOs) opened for subscription simultaneously. This rare event, which has not occurred since October 14, 1996, has brought a mix of companies to the public market, collectively aiming to raise approximately ₹4,510 crore. The companies launching their share sales include RentoMojo, Karamtara Engineering, Manipal Payment & Identity Solutions, Asset Reconstruction Company (India) Ltd (ARCIL), LCC Projects, and Steamhouse India.
Regulatory Deadlines and Market Rush
The simultaneous launch is primarily driven by a regulatory bottleneck. Many companies are rushing to launch their IPOs before September 30, 2026, to utilize their SEBI observation letters before they expire. This administrative deadline has forced a compression of issuance timelines, resulting in the current congestion of offerings. RentoMojo leads this cohort in terms of issue size, aiming to raise ₹1,255.57 crore, making it the largest among the six.
Investor Risks and Market Dynamics
For investors, this simultaneous launch presents both opportunities and potential risks. With multiple high-profile issues available at once, market liquidity may be stretched thin. This concentration of IPOs could divert funds from the secondary market, which has remained largely range-bound for over 18 months, potentially causing further stagnation in broader indices.
Another point for investors to evaluate is the composition of these IPOs. Several of these offerings include a significant portion of Offer for Sale (OFS), where existing shareholders and promoters sell their stakes to the public. In these cases, the proceeds do not go toward the company’s business operations or capital spending but rather to the exiting investors. Additionally, the rush to meet the September 30 deadline has sparked concerns about whether valuations are being set aggressively. Investors should examine the financials, debt levels, and business viability of each company individually rather than assuming strong listing gains, especially given the volatility that can follow when too many stocks enter the secondary market at once.
Looking Ahead
The subscription window for all six IPOs is scheduled to close on September 11, 2026. Following the closure, investors can expect the share allotment process to conclude by September 16, with the stocks likely debuting on the stock exchanges by September 17, 2026. The key monitorable for the market will be the subscription levels and the subsequent demand for these shares in the secondary market once listing volatility settles.
