As US Tech Giants Become Cable Giants, It’s Time We Pay Attention to Our Seabeds

Why It Matters

Control of subsea cables translates into strategic power that can be weaponized in trade disputes, threatening the resilience of international communications. Reducing dependence on U.S.-owned infrastructure is essential for European economic security and digital sovereignty.

Key Takeaways

• US firms dominate new subsea cable projects
• Trump threatens tariffs, could weaponize cable control
• Europe worries about dependence on US-owned infrastructure
• Google, Amazon, Meta building sole‑owner cables
• Calls for European alliances to counter US cable hegemony

Pulse Analysis

Undersea fiber‑optic cables carry more than 95% of the world’s intercontinental data, making them the silent backbone of the global economy. Historically, these links were built and operated by state‑owned telegraph and telephone monopolies, which limited any single nation’s ability to unilaterally disrupt traffic. The transition to privately financed consortia in the 1990s broadened ownership but still required multinational cooperation. Today, the sheer volume of bandwidth and the latency advantages of direct routes have turned the seabed into a high‑value asset for both commercial and strategic planners.

The latest wave of investment is dominated by U.S. cloud and social‑media behemoths. Google’s Atlantic‑to‑Europe system, Amazon’s Ireland‑U.S. line, and Meta’s planned 50,000‑kilometer Waterworth ring illustrate a shift from shared ventures to single‑company ownership. While these projects promise faster AI‑driven services, they also concentrate control in the hands of firms that are closely aligned with Washington’s political leadership. In a climate where President Trump has floated tariff threats and hinted at using infrastructure as leverage, the risk that cable access could become a geopolitical bargaining chip is no longer theoretical.

European governments and industry groups are responding by exploring sovereign alternatives. Initiatives to fund EU‑backed cable projects, diversify routing through non‑U.S. partners, and create regulatory safeguards aim to preserve digital sovereignty and mitigate supply‑chain vulnerabilities. The banking sector’s search for a home‑grown payment network signals a broader appetite for infrastructure independence. By fostering cross‑border collaboration and investing in resilient, multi‑owner designs, Europe can reduce the leverage that any single foreign entity—whether a state or a tech conglomerate—holds over its critical communications.
