Cube Highways Trust IPO: ₹5,000 crore OFS in 2026

What is being planned

Cube Highways Trust is preparing a ₹5,000 crore initial public offering, with the entire issue structured as an offer for sale (OFS). People familiar with the matter said the IPO is aimed at broadening the investor base and improving liquidity in the units once listed. Because it is an OFS, existing unitholders will sell their holdings to incoming investors. That also means the trust itself will not receive fresh funds directly from the offering. The structure is clearly laid out in the draft papers referenced in reports. The transaction is positioned as part of a larger shift in how the InvIT is held and traded.

OFS-only structure and what it means

An OFS-only IPO changes the purpose of the issue compared with a primary fundraise. In this case, the ₹5,000 crore size reflects units being sold by current investors rather than new capital being issued by the trust. The stated goal is to expand participation in the units and enhance trading liquidity. For investors, the key implication is that ownership will broaden, while the trust’s balance sheet does not receive IPO proceeds. Reports also describe the IPO as a potential exit route for some existing unitholders. The trust’s draft filings and the deal structure highlight liquidity and investor mix as central objectives.

From privately listed InvIT to publicly listed InvIT

Cube Highways Trust is seeking to convert from a privately listed Infrastructure Investment Trust (InvIT) to a publicly listed InvIT through this IPO. The conversion matters because participation in private trusts by some domestic institutions is constrained by local regulations tied to liquidity requirements, according to the information cited. A public listing is expected to make it easier for mutual funds and insurance companies to buy and hold units, potentially widening the pool of investors. The trust’s stated rationale for the move includes better visibility and improved liquidity. The shift is being closely watched because it is described as a first-of-its-kind transition in India’s InvIT space in reports around the filing.

Timing, regulatory filing, and roadshows

The trust filed its draft offer document with the Securities and Exchange Board of India (SEBI) on March 17, 2026, which started the regulatory process for conversion and listing. In parallel, Cube Highways Trust has begun roadshows as it engages with a select set of domestic and overseas institutions. Separate reports indicate the trust is aiming for an October launch, while other coverage also points to plans to come later this month, reflecting that the schedule may depend on demand and process timelines. One investment banker involved in the transaction said primary market volatility had been receding, creating a more stable window for large institutional fundraising. The same person noted that although the draft red herring prospectus was filed in March, it was important to wait through a more uncertain period. Pricing is expected to be decided after these institutional conversations progress.

Who may be selling in the IPO

Reports identify sponsor group entities among the unitholders looking to sell, including Cube Highways and Infrastructure II, Cube Highways and Infrastructure III, and Cube Mobility Investment. Other unitholders mentioned include Canadian infrastructure major BCI and Abu Dhabi’s sovereign wealth fund Mubadala Investment Co. Coverage also refers to the trust being backed by global investors including the Abu Dhabi Investment Authority (ADIA) and Mubadala, and mentions I Squared Capital and British Columbia Investment Management Corporation. Another reported detail is that no additional lock-in will apply to non-sponsor unitholders. The exact mix of selling unitholders and the final allocation will depend on the completed offering documents and market demand.

Asset footprint and planned additions before listing

Cube Highways Trust is described as having an asset base that it plans to expand further ahead of the IPO’s completion. Reports state that the trust plans to acquire four additional highway and tunnel project special purpose vehicles (SPVs) through swap transactions. After these additions, the asset base is expected to reach 31 projects spanning 9,811 lane kilometres. Separately, one report cites assets under management (AUM) of ₹36,520 crore. These operational and portfolio details form part of the broader context for investors assessing scale, diversification, and platform maturity.

Investor base trend and why liquidity is central

One data point highlighted in reports is the growth in the number of unitholders over time. The unitholder count rose from around 40 in April 2023 to over 400 by September 2025. That increase supports the narrative that the platform has been broadening its ownership even before a public listing. The IPO is being positioned as a step that can further widen participation by opening access through public markets. Liquidity matters for institutional investors, particularly those with constraints around tradability and position sizing. The stated intent of the listing is to improve visibility and make trading easier once units are listed.

Deal advisers and listing details

Kotak Mahindra Capital Company, HDFC Bank, HSBC Securities and Capital Markets (India) Private Ltd, and JM Financial are named as the book-running lead managers for the offering. Axis Trustee Services is the trustee, according to the materials referenced. KFin Technologies Limited is named as registrar. The units are expected to be listed on the NSE and BSE, as per the information circulated about the proposed offering. These appointments and venues are standard building blocks for executing a large institutional-focused InvIT listing.

Key facts at a glance

Why the IPO matters for the InvIT market

The proposed listing is primarily a structural shift rather than a capital-raising event for the trust, because the entire issue is an OFS. That makes it a test of public market appetite for infrastructure trust units and for secondary sales by existing institutional holders. The move is also tied to a regulatory and market reality highlighted in reports: some domestic institutions have limited participation in privately listed trusts due to liquidity requirements. If the conversion to a public InvIT proceeds as planned, it can broaden the eligible investor pool and change the investor mix. The roadshow process and SEBI review will be key near-term milestones, as pricing and final timing are expected to be linked to demand.

Conclusion

Cube Highways Trust’s planned ₹5,000 crore IPO, structured fully as an OFS, is centered on converting from a privately listed InvIT to a publicly listed one. Roadshows are underway, and the trust has already filed draft documents with SEBI dated March 17, 2026. The offering is designed to widen investor participation and improve liquidity, while providing an exit route for existing unitholders. Next steps will depend on progress in the regulatory process and the outcome of institutional engagement before final pricing and launch timing are set.
