How Mukesh Ambani Built Project Jupiter to Launch Jio’s Historic IPO

Reliance’s Secret Strategy Helped Prepare India’s Biggest Public Listing

When Mukesh Ambani addressed shareholders at Reliance Industries’ annual general meeting in August last year, he announced that Jio Platforms would pursue a stock market listing in the first half of 2026. While the statement generated excitement among investors, few knew that Reliance had already begun planning what would become one of the most ambitious IPO preparations in Indian corporate history.

Internally codenamed “Project Jupiter,” the confidential initiative was designed to prepare what is expected to be India’s biggest-ever initial public offering (IPO). Behind closed doors, Reliance executives worked for months to overcome regulatory hurdles, secure support from global investors, and finalize an IPO structure while maintaining strict confidentiality.

The draft prospectus was eventually filed shortly after Ambani confirmed Jio’s IPO plans, marking the culmination of months of carefully coordinated preparation.

What Was Project Jupiter?

Project Jupiter was Reliance’s internal codename for the highly confidential process of preparing Jio Platforms for its public market debut.

According to people familiar with the matter, the initiative officially began around October 2025 and was led by a small group of senior Reliance executives, including Chief Financial Officer V. Srikanth, KR Raja, and Jio executive Anshuman Thakur.

Only a limited number of company executives and investment bankers were involved in the project.

To maintain secrecy, Reliance reportedly minimized digital communication throughout the process. Draft prospectuses, investor presentations, and internal memorandums were largely circulated in physical form, while emails and electronic communication were kept to a minimum to avoid creating digital records.

High-level meetings were also restricted to a small circle of senior decision-makers.

How Did Reliance Prepare the IPO?

Reliance faced several complex challenges while structuring the offering.

One of the biggest tasks involved persuading regulators to relax listing requirements for mega-sized companies while simultaneously negotiating with existing shareholders regarding dilution of their ownership.

The company initially brought Kotak Mahindra Capital and Morgan Stanley into the project before expanding the syndicate of investment banks in December. Interestingly, although bankers had already begun working on the transaction, several were not formally appointed until months later, allowing Reliance to continue refining the structure before publicly announcing the mandate.

This unusual approach enabled advisers to contribute while the IPO strategy was still evolving.

How Did Existing Investors Support the Listing?

A critical part of Project Jupiter involved obtaining support from some of the world’s largest technology investors.

According to reports, investors including KKR & Co., Meta Platforms, Alphabet Inc., and other shareholders agreed to dilute approximately 8% of their holdings on a pro-rata basis.

This arrangement helped Jio meet public shareholding requirements while preserving each investor’s relative ownership percentage after the listing.

The willingness of these global investors to participate demonstrated continued confidence in Jio’s long-term growth prospects and supported the company’s path toward becoming a publicly traded business.

Why Did the IPO Structure Change?

The IPO strategy evolved significantly during the planning process.

Initially, Reliance intended to launch the offering entirely through an Offer for Sale (OFS), allowing existing investors to sell approximately 2.8% of their holdings without issuing new shares.

However, changing market conditions altered those plans.

Some shareholders reportedly expressed concerns regarding valuation amid weaker equity markets and the impact of a depreciating Indian rupee on their dollar-denominated returns.

At the same time, the Indian government introduced measures encouraging foreign capital to remain invested within the country.

Reliance ultimately decided to restructure the IPO as a fully primary issue, ensuring that the estimated $4 billion expected to be raised would remain within Jio rather than being distributed to selling shareholders.

This approach strengthens Jio’s balance sheet while providing additional capital to fund future expansion.

What Role Did Regulatory Changes Play?

Regulatory developments also proved crucial in making the transaction possible.

In September 2025, India’s securities regulator relaxed minimum public shareholding requirements for companies valued above ₹5 trillion, reducing the mandatory dilution threshold from 5% to 2.5%.

The government formally notified these changes in March 2026, removing a major regulatory hurdle for companies with exceptionally large valuations.

The revised framework provided greater flexibility for mega listings like Jio while reducing the amount of equity required to be sold during the IPO.

Why Is Jio’s IPO So Significant?

Jio Platforms’ proposed public offering is expected to become the largest IPO in Indian history, reflecting the scale of Reliance’s digital business.

The draft prospectus was officially filed on June 19, supported by 19 investment banking advisers.

The filing also marked the successful completion of Project Jupiter a confidential initiative that balanced regulatory negotiations, investor alignment, strategic restructuring, and meticulous execution over several months.

Beyond raising capital, the IPO represents another milestone in Reliance Industries’ transformation from a traditional energy conglomerate into one of India’s largest technology and digital services companies.

As investors await the public listing, Project Jupiter is likely to be remembered as one of the most sophisticated and carefully managed IPO preparations ever undertaken in India’s corporate landscape.
