STMicroelectronics Expects Its Space Business to Reach More than $3B Over Three Years

Why It Matters

The forecast positions STMicro as the dominant semiconductor supplier for the rapidly expanding LEO broadband market, promising sizable earnings growth for the company. It also underscores the strategic importance of chip co‑design partnerships for satellite operators seeking high‑volume, low‑cost production.

Key Takeaways

• STMicro expects >$3B revenue from space business 2026‑2028
• LEO revenue grew 243% to $600M by 2025
• Holds >90% LEO semiconductor market share in 2025
• Supplies custom chips for Starlink satellites, terminals, gateways
• Exploring user‑terminal market in China despite export limits

Pulse Analysis

The low‑Earth‑orbit (LEO) broadband sector is entering a phase of exponential growth as operators such as SpaceX, OneWeb and Amazon deploy thousands of satellites to deliver global internet coverage. Semiconductor demand in this niche is soaring because each satellite and its ground‑segment equipment require highly integrated, radiation‑tolerant chips that can be produced at scale. STMicroelectronics, already a European leader in analog and mixed‑signal technology, has leveraged its BiCMOS expertise to capture more than 90 % of the LEO chip market in 2025, a share that translates into a projected $600 million revenue stream by that year. The company’s 243 % revenue jump since 2021 signals that the market is still in its early innings, offering ample room for further expansion.

STMicro’s partnership with SpaceX illustrates how co‑design and high‑volume manufacturing can accelerate satellite production while keeping unit costs low. The firm supplies custom‑made chips for Starlink satellites, user terminals and gateways, enabling the constellation to scale to over 10,000 satellites and millions of terminals worldwide. By embedding its technology directly into the architecture of Starlink hardware, STMicro gains deep insight into performance requirements and can iterate faster than traditional suppliers. This collaborative model not only secures a steady revenue base but also positions the company as an indispensable technology partner for future LEO constellations.

Looking ahead, STMicro is eyeing growth beyond the Starlink ecosystem. The company is actively developing next‑generation user‑terminal chips for the Chinese market, even as European export controls prevent it from providing onboard satellite components. Additionally, the firm hints at potential involvement in emerging orbital data‑center satellites, a segment that could unlock new high‑performance computing workloads in space. For investors, the projected “well‑above $3 billion” cumulative revenue from 2026‑2028 signals a robust earnings catalyst, while the firm’s dominant market position provides a defensive moat against new entrants.
