La valoración de AST SpaceMobile para el año 2025: ¿Una “burbuja” o una revolución en la conectividad por satélite?

The stock of AST SpaceMobile (ASTS) has surged to a $20.4 billion market capitalization as of December 2025, a 382% increase from the previous year. This valuation, however, rests on a foundation of near-zero revenue and speculative bets on its satellite constellation and carrier partnerships. To assess whether this surge is sustainable, we must dissect the company's progress, partnerships, and competitive landscape.

Financials: A Tale of Hype and Hurdles

AST SpaceMobile's Q3 2025 revenue of $14.74 million, while a 1,236% year-over-year increase, fell short of analyst expectations of $22.04 million. The company reiterated its full-year 2025 revenue guidance of $50–75 million, citing $1 billion in contracted commercial revenue commitments. Yet, with a market cap exceeding $20 billion, the stock trades at a multiple that assumes near-term profitability and rapid scaling. This disconnect raises questions: Is ASTS a visionary pioneer or a speculative play?

The answer lies in its satellite deployment and partnerships.

Satellite Constellation: Building the Infrastructure of the Future

AST SpaceMobile has launched its first five "BlueBird" satellites (Block 1), providing intermittent U.S. coverage. By 2026, it plans to deploy 45–60 Block 2 satellites for continuous service across the U.S., Europe, and Japan. The company's technological milestones-successful 4G/5G connections, VoLTE calls, and video streaming using unmodified smartphones- position it as a leader in satellite-to-cellular innovation. However, delays in satellite launches or technical setbacks could derail revenue timelines.

Carrier Partnerships: Strategic Alliances or Hollow Promises?

AST's partnerships with Verizon, AT&T, and Saudi Telecom Group (stc) are its most compelling assets. Verizon's $100 million commitment and 850 MHz spectrum integration aim to extend coverage in remote U.S. areas, while stc's 10-year agreement targets the Middle East and Africa. AT&T's 2030 agreement includes spectrum and revenue-sharing components. These deals suggest strong demand for AST's technology, but their financial impact hinges on service adoption rates and contract terms. For instance, Verizon's "all-in" stance could drive early revenue, but scaling to millions of users will require infrastructure investments and customer acquisition costs that AST has yet to detail.

Competition: SpaceX's Starlink and the $43 Billion Market

SpaceX's Starlink has already launched direct-to-cell services with T-Mobile and is expanding its Gen2 network to 30,000 satellites. While Starlink's $17 billion spectrum acquisition from EchoStar and hybrid model (supplementing terrestrial networks) pose a threat, AST's unmodified smartphone compatibility offers a unique edge. The direct-to-cell market is projected to grow to $43 billion by 2032, but AST's ability to capture a meaningful share depends on execution speed and cost efficiency.

Risks and Opportunities

Risks:
- Revenue Delays: AST's Q3 revenue shortfall highlights operational risks. If Q4 guidance of $50–75 million misses, investor confidence could wane.
- Satellite Deployment: Delays in Block 2 launches or technical failures could prolong revenue timelines.
- Competition: SpaceX's scale and regulatory pushback (e.g., spectrum interference concerns) could limit AST's market access.

Opportunities:
- Carrier-Driven Growth: Partnerships with Verizon and stc could unlock $1 billion in contracted revenue, validating AST's commercial viability.
- First-Mover Advantage: AST's unmodified smartphone compatibility could differentiate it in a market dominated by hardware-dependent solutions.
- Market Expansion: The $43 billion direct-to-cell market offers long-term upside if AST secures a durable competitive position.

Conclusion: Overextended or Overlooked?

AST SpaceMobile's $20 billion valuation reflects high hopes for a future where satellite connectivity is ubiquitous. While its technological progress and carrier alliances are impressive, the stock's current price assumes rapid revenue growth and market dominance. For now, ASTS remains a high-risk, high-reward bet. Investors must weigh the company's execution risks against the transformative potential of its vision. If AST can deliver on its satellite and partnership roadmap, the valuation may prove justified. If not, the market could face a painful correction.
