The Emerging HAPS Ecosystem: Players, Policy and Growth

High-Altitude Platform Stations, or HAPS, are moving from experimental aerospace projects to a credible infrastructure layer for connectivity, surveillance and resilience. Operating in the stratosphere, typically around 18 to 25 kilometres above the Earth, these platforms combine some of the persistence of satellites with the flexibility and lower latency of aircraft. As governments and private operators seek cost-effective ways to connect underserved regions, strengthen border awareness and improve disaster response, the global HAPS ecosystem is becoming more organised, better funded and increasingly strategic.

Why HAPS is gaining momentum

The appeal of HAPS lies in a simple market reality: billions of people remain underserved by conventional digital infrastructure, while climate risk, security demands and spectrum pressure are all increasing. According to the International Telecommunication Union, roughly one-third of the world’s population still does not use the internet, with the largest connectivity gaps concentrated in rural areas across Africa and Asia. Extending terrestrial fibre and towers into low-density geographies is often uneconomic, while satellites, although essential, can face trade-offs in latency, terminal cost and capacity management.

HAPS offers an intermediate layer. A single platform can provide wide-area coverage over a footprint measured in tens or even hundreds of kilometres, remain on station for long durations and be redeployed as needs change. That makes the model attractive not only for telecom coverage, but also for intelligence, surveillance and reconnaissance, environmental monitoring and emergency communications.

This is one reason analysts continue to project strong growth. Market forecasts vary by methodology, but most point in the same direction: a sector transitioning from demonstration to early commercial deployment over the next decade. Public estimates from industry researchers commonly place the global HAPS market in the low single-digit billions of dollars today, with forecasts reaching several billion more by the early to mid-2030s as platform reliability, payload economics and regulatory frameworks mature.

The key industry players shaping the market

The HAPS ecosystem is broader than a handful of airframe developers. It includes platform manufacturers, payload integrators, telecom operators, defence contractors, solar and battery specialists, ground segment providers and regulators. Still, several names have played an outsized role in proving the category.

Airbus has been among the most visible pioneers through its Zephyr programme, a solar-electric stratospheric aircraft designed for ultra-long endurance missions. Zephyr has demonstrated the operational potential of lightweight, solar-powered systems for both connectivity and defence applications, and it remains one of the best-known HAPS platforms globally.

AALTO, which emerged to commercialise Zephyr-based capabilities, is also helping define the business model for persistent stratospheric services. Its focus reflects a wider industry shift: HAPS is no longer being treated purely as an aerospace engineering challenge, but as a service platform for telecom, Earth observation and government missions.

In Japan, SoftBank has been a major force behind the sector through HAPSMobile and its work on the Sunglider concept. SoftBank’s involvement signalled early that major telecom stakeholders saw strategic value in stratospheric infrastructure, especially for rural broadband and temporary network restoration.

In the United States, multiple companies have explored stratospheric balloons, fixed-wing aircraft and hybrid approaches. While some high-profile projects have been scaled back or restructured, they have still advanced enabling technologies in autonomy, lightweight materials, communications payloads and energy systems. The ecosystem has benefited from these lessons, even where individual programmes did not reach full commercial scale.

What matters now is that the market is diversifying. The next wave is likely to include specialised providers focused on regional deployments, sovereign applications and tailored payload integration rather than only global-scale moonshot initiatives. This creates an opening for agile European companies with a clear operational focus in high-growth markets.

Government programmes are accelerating adoption

Public sector involvement is one of the strongest signals that HAPS is becoming strategically important. Governments view stratospheric platforms not only as telecom tools, but also as assets for national resilience.

In defence and security, HAPS can support border monitoring, maritime domain awareness and persistent ISR at lower cost than some conventional airborne systems. In civil applications, they can restore communications after floods, earthquakes or cyclones, particularly where ground infrastructure has been damaged.

Japan has been especially active in supporting HAPS-related development, aligning industrial policy with telecom innovation and advanced aerospace capabilities. In Europe, regulatory and institutional interest has grown through discussions involving the European Union Aviation Safety Agency, the European Conference of Postal and Telecommunications Administrations and the International Telecommunication Union, all of which have roles in airspace integration and spectrum harmonisation.

The ITU’s identification of spectrum frameworks for HAPS has been a particularly important step. Spectrum certainty is essential if telecom operators and investors are to treat HAPS as deployable infrastructure rather than a niche experiment. National regulators across Africa and Asia will play a decisive role here, especially as demand grows for rural coverage, smart agriculture connectivity and sovereign communications capacity.

Government demand may, in fact, be the sector’s first large-scale revenue anchor. Defence ministries, civil protection agencies and universal service programmes can provide the long-duration contracts needed to de-risk deployment, while commercial telecom use cases scale in parallel.

Market forecasts and the path to commercial scale

The next five to ten years will determine whether HAPS becomes a mainstream infrastructure layer. The direction of travel is promising, but success will depend on execution in three areas.

First is endurance and reliability. Operators need platforms that can remain on station for extended periods, survive stratospheric conditions and carry commercially meaningful payloads. Second is unit economics. HAPS must prove that they can deliver coverage or sensing services at a lower total cost than alternatives in specific use cases, particularly in remote and disaster-prone regions. Third is regulation. Airspace access, cross-border operations and spectrum licensing must become more predictable.

Where those conditions align, the opportunity is significant. Sub-Saharan Africa and South Asia are especially compelling target markets due to large rural populations, uneven terrestrial infrastructure and strong demand for digital inclusion. GSMA data has consistently shown that mobile internet adoption still lags network coverage in many lower-income markets, creating room for solutions that reduce deployment costs and improve service availability.

For investors and policymakers, the message is clear: HAPS is not a replacement for terrestrial networks or satellites, but a complementary layer that can fill critical gaps. As launch costs, battery performance, solar efficiency and autonomous flight systems continue to improve, the commercial case becomes stronger.

Why the ecosystem matters now

The emerging HAPS ecosystem is no longer defined by isolated prototypes. It is being shaped by industrial partnerships, telecom strategy, defence demand and regulatory progress. The winners will be companies that understand not just the aircraft, but the full operating model: payloads, spectrum, service integration, sovereign requirements and regional market needs.

That is where focused players can create disproportionate value. For emerging markets in Africa and Asia, HAPS has the potential to support affordable connectivity, strengthen disaster resilience and extend critical services where conventional infrastructure falls short.
