Underappreciated Verticals: Aviation and Maritime

In this episode of Valley of Depth, we sit down with Jack Kuhr, Payload Pro’s Research Director, to unpack what SpaceX has become on the eve of what could be the largest IPO in history. What began as a launch company has evolved into a vertically integrated platform spanning launch, satellites, global connectivity, and potentially AI and compute in space.This is the first in a series of conversations where we’ll regularly update our audience on the latest developments shaping SpaceX and its impact on the broader space economy.

We discuss:

• How Starlink has overtaken launch as SpaceX’s primary growth engine
• Why Starlink’s constraints are more likely terminals, regulation, and physics—not satellites
• How international markets are powering the next phase of Starlink’s expansion
• Why aviation and maritime are the most underappreciated Starlink verticals
• Whether Starlink “Lite” can meaningfully take share from traditional ISPs
• How Starship and Starlink V3 could upend Falcon 9 economics
• Why the SpaceX–xAI merger points to a fully integrated space, connectivity, and AI stack
