There is no bigger story in Indian infrastructure right now than the battle being fought over who controls India's skies. Not the airlines — they come and go, merge and restructure, and have never reliably made money in this country. The real wealth in Indian aviation is being built by the two companies that own the runways, the terminals, the retail concessions, and the cargo sheds. GMR Airports and Adani Airports are building empires so large, so capital-intensive, and so strategically consequential that the government itself is now considering capping how many airports any single player can control.
That, more than any financial metric, tells you how significant this battle has become.
THE TWO EMPIRES: VERY DIFFERENT BY DESIGN
Start with the numbers that matter most - passengers.
GMR, with three airports — Delhi, Hyderabad, and Goa — handled the highest passenger footfall of 120.57 million passengers in FY25, compared to 94.44 million by Adani during the same period. GMR wins on volume despite having fewer airports, because it operates two of the three busiest airports in India. Adani wins on breadth — eight airports across the country, soon to be more, covering every major geographic region.
GMR Airports, as the largest private airport operator in Asia and second-largest globally, served over 121 million passengers in FY24. Its portfolio spans Delhi, Hyderabad, Goa-Mopa, Nagpur, Bidar, and Medan in Indonesia, while providing technical services at Mactan-Cebu International Airport in the Philippines. Adani Airport Holdings, representing nearly 23% of India's passenger movements and about a third of cargo traffic, controls eight airports — Ahmedabad, Jaipur, Lucknow, Guwahati, Mumbai, Navi Mumbai, Mangaluru, and Thiruvananthapuram.
Two different philosophies. Two different balance sheets. One enormous opportunity.
GMR: THE DELHI TARIFF WINDFALL THAT CHANGED EVERYTHING
The most important financial development in Indian airport infrastructure in the past eighteen months was the Delhi Airport tariff revision under Control Period 4 — and it has been a transformative event for GMR. Aeronautical yield per passenger at Delhi Airport jumped to ₹469 in Q2 FY26 — a massive 69% year-on-year increase. For H1 FY26, aeronautical yield averaged ₹433 per passenger, up 59% year-on-year despite flat traffic. Delhi Airport alone recorded 166% year-on-year growth in aeronautical income in Q2 FY26, lifting total income to ₹18.5 billion and EBITDA dramatically.
For Q3 FY26, GMR Airports Infrastructure announced consolidated revenue of ₹3,994 crore — a substantial 50.5% increase year-on-year. EBITDA reached ₹1,700 crore, up 71% year-on-year. Jefferies expects GMR's EBITDA CAGR of 32% over FY24 to FY27, projects PAT positive in FY26, and expects leverage ratios to moderate to Net Debt/EBITDA of 4–5x in FY26 versus 10–12x in FY23–FY24.
A tribunal also allowed both GMR and Adani Airport to include non-aeronautical revenue in the tariff model — boosting earnings at Delhi and Mumbai airports further, though airlines and flyers may face higher charges as a result. The non-aeronautical story is equally compelling. GMR's non-aeronautical revenues at Delhi rose 11% YoY to ₹17.3 billion in H1 FY26, while Hyderabad Airport saw a stronger 28% growth. In Hyderabad, retail and duty-free accounted for 29% of non-aero income, F&B at 20%, advertising at 13%, and car parking at 11%.
GMR'S EXPANSION PIPELINE: BHOGAPURAM, NAGPUR, AND A GLOBAL FOOTPRINT
Here is where GMR's story becomes considerably more interesting than most people realise — because the company is simultaneously developing three new airport projects while operating five existing ones, and expanding internationally.
Bhogapuram Airport — The Andhra Pradesh Gateway
Construction of the Bhogapuram International Airport is progressing significantly ahead of schedule. The project — being developed on a 2,200-acre site, designed to handle 6 million passengers annually — was contractually slated for December 2026 but is now targeting completion by July 2026, six months ahead of schedule. The company has already completed approximately 80% of infrastructure work.
GMR Visakhapatnam International Airport Limited holds a 40-year DBFOT concession to develop the airport, which will serve as the new gateway to Andhra Pradesh — replacing the existing Visakhapatnam Airport and doubling its initial capacity. A successful validation flight was completed in January 2026, marking a key milestone toward operational readiness. Bhogapuram is not just a new airport. It is being developed in one of India's most strategically important industrial corridors — adjacent to the Krishnapatnam port, the Adani Group's own data centre campus, and the emerging Visakhapatnam industrial cluster. The airport's initial 6 million passenger capacity understates its long-term strategic importance.
Nagpur Airport — The Central India Hub
GMR has signed a concession agreement for the upgrade, development, and operation of Dr. Babasaheb Ambedkar International Airport in Nagpur — upgrading it as a major regional hub for passenger and cargo operations. Nagpur handled 2.89 million passengers in FY25, with aircraft movements growing 8.5% and cargo growing 12.8%. Nagpur sits at the geographic centre of India, making it a natural cargo and logistics hub — a dimension that GMR intends to develop aggressively under its operations.
International Operations — Indonesia, Philippines, Greece
GMR operates Kualanamu International Airport in Medan, Indonesia — a major Western Indonesia hub developed through a 25-year partnership, designed for high capacity. It also provides technical services at Mactan-Cebu International Airport in the Philippines.
Most significantly, GMR is developing a new international airport in Crete, Greece — winning the bid to design, build, operate, and maintain the new facility. The Crete project puts GMR in the company of global airport developers operating in premium European tourism markets — a positioning that no other Indian airport company has achieved.
The combined international portfolio — Medan operations, Philippines technical management, and Crete development — makes GMR genuinely the only Indian airport operator with a diversified global presence. It is not just building airports. It is building airport expertise that is being recognised and contracted internationally.
ADANI AIRPORTS: THE SCALE MACHINE WITH A ₹1 LAKH CRORE PLAN
Adani's airport strategy is the most ambitious infrastructure programme any Indian conglomerate has ever attempted in a single sector. And it is being executed by Jeet Adani — the Chairman's son — who has made airports his primary domain. Adani Airport Holdings plans to invest more than $11 billion — approximately ₹1 lakh crore — in its airports business by 2030, targeting terminals, runways, aircraft-handling facilities, and passenger amenities. Jeet Adani confirmed the group is preparing for an IPO by FY28, likely through a demerger from Adani Enterprises.
Navi Mumbai: The Crown Jewel
Prime Minister Narendra Modi inaugurated the new Navi Mumbai International Airport — built by the Adani Group at a cost of $2.2 billion — in October 2025, with commercial operations beginning in December 2025. The airport is designed to handle 20 million passengers annually in Phase 1, with a long-term vision to scale to 90 million passengers — making it ultimately comparable to the world's largest airport hubs. Air India Express commenced 20 daily departures from Navi Mumbai at launch, with plans to scale to 55 daily departures by mid-2026 including international routes, and 60 daily departures by Winter 2026.
Navi Mumbai makes Mumbai the first Indian city with a dual-airport system — a milestone that matches London, New York, and Tokyo in aviation infrastructure sophistication. More importantly for Adani, controlling both Mumbai airports gives it near-complete commercial control over India's financial capital's air access.
THE 11-AIRPORT PRIVATISATION: THE GAME THAT WILL DEFINE THE DECADE
The Indian government is leasing out government-owned airports to private players while incentivising new construction. It plans to have 350 to 400 airports by 2047 from 163 currently. New Delhi has outlined plans to lease out 11 airports, including Amritsar and Varanasi.
Adani Enterprises has confirmed plans to bid for all 11 state-owned airports slated for privatisation — including major hubs like Bhubaneswar, Varanasi, Amritsar, and Indore, which will be bundled with smaller regional facilities. But here is the regulatory wildcard that most analysis ignores: the government is considering capping bids from a single player for the 11 airports — driven by concerns over market concentration and the risk of monopoly in civil aviation infrastructure. Discussions are ongoing about framing bidding rules to encourage competition.
This regulatory development matters enormously for both companies. If the cap is imposed at, say, three additional airports per bidder, Adani — already at eight — may be severely restricted from expanding its domestic portfolio further. That would leave the remaining airports available for GMR, creating an opening for the quality-focused operator to add scale without the political risk that comes with appearing to consolidate too much critical national infrastructure.
GMR, with its current portfolio of five Indian airports plus three international, is significantly better positioned than Adani to benefit from a bidding cap scenario. It can bid aggressively for multiple airports in the new round without triggering the concentration concerns that would limit Adani.
THE ADANI IPO: THE MOST WATCHED LISTING IN INDIAN INFRASTRUCTURE
Jeet Adani has stated the IPO depends on three milestones: successful operations at Navi Mumbai, completion of surrounding commercial development, and financial self-sustainability. He described a demerger from Adani Enterprises as "the better route as it unlocks greater value for Adani Enterprises shareholders" and confirmed the group is open to bringing in a strategic investor before listing. The airport unit secured a $750 million investment from a consortium of international banks, part of which was used to refinance $400 million in existing debt.
When Adani Airports lists — targeted by FY28 — it will be one of the most significant Indian infrastructure IPOs in a generation. A portfolio of eight to potentially fifteen airports, with Navi Mumbai as the flagship and Mumbai as the cash cow, will attract global infrastructure investors at valuations that current Adani Enterprises shareholders are not fully capturing.
THE VERDICT: QUALITY VERSUS QUANTITY, INDIA VERSUS GLOBAL
The GMR-Adani comparison is ultimately not about which company is better. Both are building genuinely important infrastructure that India needs. The comparison is about which strategy is more durable, more capital-efficient, and more resistant to the regulatory and competitive risks that accompany being in a politically sensitive, geographically concentrated infrastructure business.
GMR's quality concentration — in two world-class airports that handle the highest-value passengers and cargo in India, plus a growing international portfolio — creates a defensible earnings base that does not depend on whether the government awards the next twelve airports favourably. The Delhi tariff reset has already created the earnings step-change that proves the model. Bhogapuram and Nagpur add capacity without diluting quality. Crete adds an entirely new geography where Indian airport operating expertise commands a premium.
Adani's scale ambition is the most exciting large-infrastructure story in India right now. Navi Mumbai's potential — eventually 90 million passengers — combined with a Mumbai dual-airport monopoly creates an asset base of staggering long-term value. But it requires ₹1 lakh crore of capital deployment on a five-year timeline, depends heavily on government goodwill for further airport awards, and faces the specific risk that the concentration cap under consideration could limit the very expansion that justifies the current investment rate.
India's aviation market is growing fast enough — with 15–16% annual growth projected for the Indian aviation industry — that both strategies will generate significant value. The question for investors is which one generates it more reliably, with less capital risk, and with better resilience to regulatory change. Right now, on those criteria, GMR's quality-depth-global approach is the more measured bet. Adani's scale-and-capture approach is the higher-conviction, higher-risk one.
One thing is certain: whoever wins the next eleven airports will hold a position in Indian infrastructure that will compound for decades. The government's bidding cap consideration — designed to prevent monopoly — may paradoxically be the most important short-term catalyst in determining which of these two empires grows faster from here.
