India’s biggest IPO story may be quietly taking shape.

Billionaire Mukesh Ambani-led Reliance Industries is reportedly gearing up for a blockbuster listing of its digital arm, Jio Platforms Ltd., and has already roped in a heavyweight lineup of global and domestic investment banks. Names like BofA Securities, Citigroup, Goldman Sachs, Morgan Stanley, JM Financial, and Kotak Mahindra Capital are said to be advising on the deal, signalling the scale and ambition behind the proposed offering.

If executed, this could turn out to be India’s largest-ever IPO, with estimates suggesting a fundraising of over $4 billion. Notably, this would also mark Reliance’s first major subsidiary listing in nearly two decades — a move that could unlock significant value for shareholders.

The timing appears strategic. Recent regulatory changes now allow large companies to list with just a 2.5% public float, making it easier for mega corporations like Jio to tap the markets without significant dilution. Based on earlier banker estimates, Jio Platforms could command a valuation of around $170 billion, putting it among the most valuable telecom-digital companies globally.

At its core, Jio Platforms is far more than a telecom operator. It is a full-stack digital ecosystem spanning telecom (Reliance Jio), broadband, enterprise connectivity, cloud services, digital apps, content platforms, and fintech initiatives. With over 450 million subscribers, Jio has fundamentally reshaped India’s data consumption landscape and continues to expand aggressively into high-margin digital services.

Financially, the business has been showing strong momentum. Jio Platforms reported annual revenue of over Rs. 1.2 lakh crore, with net profit exceeding Rs. 20,000 crore, reflecting robust operating leverage and scale benefits. Its consistent cash generation and expanding digital footprint are key factors driving investor interest ahead of the IPO.

The next key trigger will be the filing of the draft red herring prospectus (DRHP) with SEBI, once the structure and timeline are finalised. However, as with any mega listing, the final size, valuation, and timing will remain closely tied to market conditions.

If this IPO goes through as expected, it won’t just be another listing — it could redefine the scale and global perception of India’s capital markets.
