In 2025, the Indian market witnessed a significant divergence in the fortunes of its largest business houses. Mukesh Ambani's Reliance Group solidified its position as the nation's foremost wealth creator, while the esteemed Tata Group encountered substantial headwinds, resulting in a notable erosion of its market value. The Reliance Industries Group saw its combined market capitalization surge by an impressive ₹4.6 lakh crore, reaching a total of ₹23.44 lakh crore. This growth was primarily fueled by a nearly 30% rise in the stock price of its flagship entity, Reliance Industries Ltd (RIL), underscoring strong investor confidence in its diversified business model spanning from energy and retail to telecommunications.
Following Reliance, other major conglomerates also posted strong gains. Sunil Mittal's Bharti Group secured the second position, adding ₹3.5 lakh crore to its investor wealth and elevating its group market cap to ₹14.6 lakh crore from ₹11.1 lakh crore at the beginning of the year. The Bajaj Group ranked third, contributing a combined market value addition of ₹2.6 lakh crore. The HDFC Group and the Adani Group rounded out the top five, adding ₹2.2 lakh crore and ₹1.1 lakh crore, respectively. The Adani Group's market capitalization climbed to ₹14 lakh crore during this period, demonstrating resilience and continued growth.
Collectively, India’s top seven conglomerates—Tata, Reliance, HDFC, Bharti Group, Bajaj, Adani, and ICICI Group—added close to ₹10 lakh crore to their market capitalisation in 2025. The Reliance Group was the standout performer, accounting for 48% of this total wealth creation. The Bharti Group was the second-largest contributor with a 36% share. The combined market capitalization of these seven business empires now stands at ₹122 lakh crore, which represents nearly 60% of the total market cap of the Nifty 50 index, valued at ₹207 lakh crore. This concentration of wealth highlights their systemic importance to the Indian economy and stock market.
In stark contrast to its peers, the Tata Group emerged as a wealth destroyer in 2025. The conglomerate's flagship company, Tata Consultancy Services (TCS), bore the brunt of the losses, shedding nearly ₹3 lakh crore in market capitalization. This decline was attributed to a confluence of factors, including slower earnings growth in the IT sector, uncertain revenue visibility amid global economic shifts, and structural changes driven by the rapid adoption of AI, cloud computing, and automation. The challenges were not confined to TCS; other group companies such as Trent, Tata Elxsi, Voltas, and Tata Technologies also experienced declines ranging from 20% to 40% since the start of the year. Barring a handful of exceptions, most stocks within the Tata group delivered negative returns to investors in 2025.
Despite the mixed market environment, the outlook for Reliance Industries remains overwhelmingly positive. According to analysts at Morgan Stanley, RIL's earnings estimates are projected to be upgraded every quarter through 2026, which could pave the way for a significant valuation re-rating. The global brokerage reiterated its "overweight" rating on the stock and increased its price target from ₹1,701 to ₹1,847. Analysts noted that since the COVID-19 pandemic, Reliance has invested over $80 billion in its businesses, yet the stock's current valuation only reflects mid-cycle earnings for its existing verticals. The market, they argue, has not fully appreciated the monetization cycle and the company's capital redeployment into new growth engines.
Further upside for Reliance could be unlocked through its digital services arm, Jio Platforms Ltd. The subsidiary is widely expected to enter the primary market with an initial public offering (IPO) next year, a move that could provide a substantial boost to the group’s overall market capitalisation. This sentiment is shared across the analyst community, with 35 out of 37 analysts covering RIL maintaining a "buy" recommendation on the stock, indicating strong conviction in its future growth trajectory. This positive outlook contrasts sharply with the challenges facing other legacy conglomerates, positioning Reliance to continue its dominance in the Indian market.
The year 2025 has clearly demarcated the leaders from the laggards among India's largest business groups. Reliance Industries' strategic investments in high-growth sectors have paid off handsomely, cementing its status as the country's premier wealth creator. Meanwhile, the Tata Group faces a period of introspection and strategic realignment to navigate the structural shifts impacting its key businesses. For investors, this divergence underscores the importance of sector-specific dynamics and a company's ability to adapt to a rapidly evolving economic landscape.
