Three separate but converging developments over the past 48 hours illustrate that the direct-to-device (D2D) satellite connectivity market has crossed from experimental pilot phase into genuine commercial buildout. First, Hubble Network, an operator building a Bluetooth-based direct-to-satellite IoT constellation, announced on September 23 the completion of a $200 million Series C financing round, pushing its private market valuation to $1.6 billion. Second, at World Space Business Week in Paris, the outgoing director of the ITU Radiocommunication Bureau stated publicly that he expects the 2027 World Radiocommunication Conference (WRC-27) to produce a formal regulatory framework for direct-to-device services in mobile spectrum bands, noting that the GSMA already counts 151 mobile operators with satellite services live, in testing, or planned. Third, Airtel Africa and Starlink launched their satellite-to-mobile service in Uganda, marking the second African market where the service has gone commercially live.
Each of these developments individually would be a notable industry data point. Together, they describe a market that is simultaneously attracting serious growth capital, approaching international regulatory clarity, and already generating live commercial deployments in emerging markets where terrestrial cellular infrastructure gaps make satellite-based connectivity most economically compelling.
Direct-to-device satellite connectivity, the ability for standard smartphones and IoT devices to connect directly to satellites without specialized terminals, has been discussed as a transformative technology for years but has struggled with an unsettled business model, fragmented spectrum rules, and technology that was until recently more proof-of-concept than production-grade. The events of the past two days suggest that period of uncertainty is ending on multiple fronts simultaneously.
The GSMA's count of 151 operators building toward direct-to-device, with no settled business model, tells you the market has moved past the question of whether this technology works and into the harder question of who gets paid and how much.

Hubble Network's valuation jump is particularly significant because it applies specifically to the IoT and Bluetooth-device connectivity niche within the broader D2D category, distinct from the smartphone-focused approaches pursued by Starlink Direct to Cell and AST SpaceMobile. A $1.6 billion valuation for a company focused on connecting Bluetooth tags, trackers, and low-power IoT devices directly to satellites signals investor confidence that the addressable market extends well beyond consumer smartphone texting use cases into asset tracking, logistics, agriculture, and industrial IoT applications where terrestrial cellular coverage is inconsistent or absent.
The ITU's signal on WRC-27 matters because spectrum access has been the single largest regulatory bottleneck constraining D2D scale-up. Mobile network operators hold exclusive rights to their licensed spectrum bands in most jurisdictions, and satellite operators wanting to connect directly to unmodified smartphones need either spectrum sharing arrangements with those MNOs or new allocated bands, both of which require international coordination. A formal WRC-27 framework would give both satellite operators and mobile network operators the regulatory certainty needed to commit long-term capital to D2D infrastructure and commercial partnerships at scale, rather than operating through bilateral, market-by-market agreements as is largely the case today.
The Airtel Africa and Starlink Uganda launch demonstrates that, regulatory uncertainty notwithstanding, commercial deployment is already happening in markets where the economic case is strongest. Sub-Saharan Africa has some of the lowest terrestrial cellular tower densities in the world relative to population and geographic area, making satellite-based direct connectivity a genuinely superior economic proposition compared to building out additional terrestrial infrastructure in low-density rural areas.

For satellite operators, the D2D market is bifurcating into at least two distinct commercial tracks: consumer smartphone messaging and voice services (Starlink Direct to Cell, AST SpaceMobile, Lynk Global), and IoT/asset-tracking services (Hubble Network and similar players). Each track has different spectrum requirements, different partnership structures with mobile network operators, and different total addressable markets. Investors and industry participants should stop treating D2D as a monolithic category and instead evaluate operators based on which specific sub-market they are targeting.
For mobile network operators, the GSMA's count of 151 operators building toward D2D signals near-universal recognition that satellite connectivity will become a standard feature of mobile service offerings rather than a niche add-on. This creates both partnership opportunities and competitive risk: MNOs that move early to secure exclusive or preferential satellite partnerships (as Airtel Africa has done with Starlink) gain a coverage differentiation advantage, while those that delay risk being locked out of the best partnership terms as satellite operators consolidate their MNO relationships market by market.
For emerging market telecom infrastructure, the Uganda launch reinforces a pattern already visible in other African markets where Starlink and local telecom partners have moved faster on D2D commercial launches than has been typical in more mature, infrastructure-dense markets. This suggests Africa and other underserved regions may serve as the primary commercial proving ground for D2D economics, with lessons learned there informing eventual rollout strategies in North America, Europe, and Asia where existing terrestrial infrastructure is denser and the incremental value proposition of satellite connectivity is comparatively lower, at least for consumer use cases.
For the venture capital and private equity community, Hubble Network's $1.6 billion valuation on a $200 million raise sets a new benchmark for D2D IoT valuations and will likely accelerate funding activity for competing constellations in the space, IoT connectivity, and asset-tracking niches. Expect increased deal flow and higher valuations across adjacent players as investors seek exposure to what is increasingly being treated as a validated market category rather than a speculative technology bet.
For spectrum regulators and policymakers, the tension SatNews highlighted, 151 operators building toward D2D with no settled business model, underscores that technical and regulatory readiness is outpacing commercial and legal clarity. WRC-27 will be a genuinely consequential conference, and the two-year runway before it convenes gives operators, MNOs, and national regulators a defined window to develop the commercial frameworks (revenue sharing, roaming-equivalent agreements, liability allocation) that will need to accompany whatever spectrum framework emerges.
Expect the next 12 to 18 months to bring a wave of additional D2D commercial launches in emerging markets, following the Uganda template, as satellite operators and MNOs seek to establish market position ahead of the WRC-27 regulatory framework. Africa, Southeast Asia, and Latin America are the most likely venues for continued expansion given the combination of coverage gaps and comparatively simpler bilateral regulatory paths compared to spectrum-dense developed markets.
On the capital markets side, Hubble Network's valuation will likely trigger comparable funding rounds for competing IoT-focused D2D operators over the coming two quarters, as venture investors seek to establish positions before valuations climb further. Watch for consolidation activity as well: with 151 operators building toward D2D and no settled business model, the market has more participants than the eventual revenue pool can likely support at current valuations, making acquisition or partnership consolidation a probable outcome over the next 24 months.
The most consequential single event on the horizon remains WRC-27 itself. The outgoing ITU spectrum chief's public expectation that the conference will produce a workable regulatory framework should be read as an informed but not guaranteed forecast. Spectrum negotiations of this complexity, involving competing claims from mobile network operators protecting their licensed bands and satellite operators seeking new allocations, have a track record of running longer and producing more compromised outcomes than early optimism suggests. Industry participants should treat 2027 as a directional target for regulatory clarity rather than a guaranteed resolution date, and should continue building commercial partnerships under existing bilateral frameworks in the interim, exactly as Airtel Africa and Starlink have done in Uganda.
Hubble Network's $1.6 billion valuation signals investor confidence that direct-to-device connectivity extends well beyond smartphone messaging into IoT and asset-tracking markets.
WRC-27 is expected to produce a formal international regulatory framework for D2D spectrum, but the 151 operators building toward the technology still lack a settled business model.
Airtel Africa and Starlink's Uganda launch confirms that emerging markets with low terrestrial infrastructure density are the leading commercial proving ground for D2D economics.
Expect increased funding activity and consolidation among competing D2D operators over the next 24 months as valuations rise and the addressable revenue pool becomes clearer.
The D2D market is bifurcating into consumer smartphone and IoT sub-markets, each with distinct spectrum needs, partnership structures, and total addressable markets that investors and operators should evaluate separately.
