How duopoly markets are quietly reshaping India’s economy

India’s key sectors are increasingly dominated by powerful duopolies, offering efficiency but creating risks of fragility, pricing power, and reduced innovation.

One morning, while booking a flight from Mumbai to Bengaluru, something felt odd. Every reasonable option came from either IndiGo or Air India. Later that day, while recharging my phone, the choice again narrowed to two: Jio or Airtel. Ordering a book meant Amazon or Flipkart. Splitting a bill happened, predictably, via PhonePe or Google Pay.

Without announcement or alarm, India has entered the age of two—a phase where duopolies quietly shape everyday transactions. Whether we shop, pay, fly, or connect, much of our economic life increasingly flows through two dominant players. The shift has been so seamless that most of us barely notice it.

The comfort of two—and the cost

At first glance, duopolies seem reassuring. Two strong firms imply stability, reliability, and scale. For consumers, friction reduces. For policymakers, oversight appears simpler. For investors, it signals market maturity.

Economics, however, offers a sterner view. A duopoly sits precariously between competition and monopoly—“too few to compete vigorously, too many to collude openly” (Tirole, The Theory of Industrial Organization). In sectors with high entry barriers—telecom infrastructure, aircraft fleets, logistics networks, digital payments—duopolies are not accidental; they are almost inevitable.

India’s economy is now dotted with them.

Telecom: When two networks carry a nation

India’s telecom price wars of the 2010s drove data costs to global lows, but the casualties were many. Smaller operators disappeared and Reliance Communications collapsed. What emerged were Jio and Airtel, now controlling over 80 percent of the mobile broadband market.

Initially, consumers benefited. Once the dust settled, tariffs began creeping up. With Vodafone Idea struggling and BSNL lagging technologically, competitive pressure eased. When Jio or Airtel revises prices, the other typically follows within days—classic parallel pricing in a duopoly.

The deeper concern is systemic fragility. When two networks underpin payments, logistics apps, banking OTPs, telemedicine, and governance systems, failures cascade nationally.

UPI: Open infrastructure, closed competition

UPI is India’s most celebrated policy innovation—a public digital payments rail admired globally. But the apps riding on it tell another story. PhonePe and Google Pay process more than 80 percent of UPI transactions.

This dominance isn’t born of anti-competitive behaviour but of early-mover advantage, design, and scale. Still, it raises structural questions. Two private apps now wield immense influence over user data, merchant visibility, and ecosystem incentives. Regulators spotted this early, proposing a 30 percent market-share cap—a rule repeatedly deferred because enforcing it could destabilise a critical system.

UPI was built to democratise payments. Its success has produced a platform duopoly atop a public pipe—a tension India must manage carefully.

E-commerce: Amazon vs Flipkart and the ONDC gambit

Online retail in India is effectively a two-horse race. Amazon and Flipkart together control more than two-thirds of the market. For customers, this brings fast delivery and easy returns. For sellers, it creates dependence on algorithms that decide visibility, pricing, and promotions.

The Competition Commission of India has flagged concerns around preferential sellers, exclusivity, and search bias. Consumers see variety, but it is curated by two gatekeepers.

India’s response is unusual. The Open Network for Digital Commerce (ONDC) doesn’t seek to break the duopoly but to redesign the market architecture—shifting power from platforms to protocols, and from proprietary algorithms to interoperability. It is a bold experiment, watched globally.

Food delivery: Convenience narrowed to two choices

Few sectors reflect India’s age of two as sharply as food delivery. Swiggy and Zomato together control around 95 percent of the market. Built through logistics scale, burn-rate stamina, and relentless user acquisition, the duopoly works smoothly for customers: predictable delivery times, refined apps, and instant refunds.

But choice is wide, not diverse. The same cloud kitchens, promoted listings, and algorithm-driven menus appear everywhere. With fewer competitors, surge pricing and delivery charges have edged upwards. Price innovation has slowed even as convenience has peaked.

For restaurants, dependence on two platforms reduces bargaining power. Discovery is no longer organic; it is bought, boosted, and ranked. When demand is controlled by a duopoly, restaurants become suppliers rather than partners.

Aviation: When two airlines dominate the skies

Recent IndiGo disruptions have highlighted aviation’s concentrated structure. With IndiGo holding roughly 65 percent of the domestic market, the sector oscillates between a duopoly and a near-monopoly. For years, this seemed beneficial: IndiGo delivered efficiency and reliability, while Air India, under Tata’s stewardship, began modernising its fleet and operations.

But stability is a double-edged sword. When one airline carries more than 60 percent of domestic passengers, an operational failure becomes a national event. The IndiGo meltdown—thousands of cancellations and delays—triggered fare caps, regulatory intervention, and public outrage. A private crisis became a public policy emergency.

In aviation duopolies, efficiency concentrates, but so does fragility.

What global duopolies teach us

India’s experience mirrors global patterns:

  • Visa and Mastercard dominate 90 percent of global non-China card payments, offering reliability but high merchant fees.
  • Android and iOS control mobile operating systems, driving innovation while drawing accusations of gatekeeping.
  • Boeing and Airbus supply most commercial aircraft, delivering scale but exposing systemic vulnerabilities during crises.
Across sectors, duopolies are efficient yet brittle, innovative yet controlling.

But duopolies aren’t all bad

They often:
  • build world-class infrastructure faster than fragmented markets,
  • invest heavily in innovation during early rivalry,
  • standardise platforms and improve reliability,
  • accelerate adoption through scale.
India’s telecom rollout, UPI’s growth, and e-commerce logistics were enabled by a few players committing vast capital at speed. The problem begins when strength hardens into inertia.

Are duopolies bad for businesses themselves? Surprisingly, yes.

  • Regulatory bullseye: Duopolies attract antitrust scrutiny. India’s giants are no exception.
  • Strategic predictability: With each firm watching the other, innovation becomes incremental.
  • Dependency risk: When firms become critical infrastructure, governments intervene quickly during crises, limiting strategic freedom.

What this means for India’s next decade

India cannot avoid duopolies in high-infrastructure, network-driven sectors. But it can build guardrails that prevent them from becoming monopolistic or fragile. Duopolies are not villains; they are simply firms that scaled faster than the rest.

The real question is how the next act is written. If India can balance openness with scale, and innovation with concentration, it can show that power need not become absolute. The age of two need not be the age of limits—if it becomes the age of balance.
