# defense spending is the new catalyst for space investment with US Space Force budget jumping 39 percent in one year to 40 billion

The US Space Force budget jumped from $28.7 billion in FY2025 to a requested $39.9 billion for FY2026 — an $11.3 billion increase, the largest in USSF history. The Golden Dome missile defense shield is the major new program driver. Global military space spending topped $60 billion in 2024. This defense demand signal is reshaping private capital flows into the space sector.

Defense-connected companies are attracting capital at a pace that outstrips purely commercial ventures: True Anomaly raised $260 million (Series C, July 2025) for space domain awareness. K2 Space raised $110 million (February 2025) for large satellite buses. Stoke Space raised $510 million (Series D, October 2025) for defense-positioned reusable launch. Rocket Lab's $816 million SDA contract for missile-warning satellites demonstrates that government demand creates substantial revenue streams, not just startup funding. Space VC investment surged 158.6% in H1 2025 versus H1 2024.

The defense catalyst has shifted the composition of space investment. Late-stage deals reached ~41% of total — the highest percentage in a decade — as investors favor more mature projects with government revenue visibility. What is cooling: pure-play space tourism, single-use launch vehicles, and early-stage companies without a defense or government revenue path.

The defense spending surge is not a temporary stimulus but a structural shift in how governments perceive space — from a science and exploration domain to critical national security infrastructure requiring continuous large-scale investment. This connects to [[governments are transitioning from space system builders to space service buyers which structurally advantages nimble commercial providers]] — defense spending flows increasingly through commercial procurement channels, accelerating the builder-to-buyer transition.

Relevant Notes:
- [[governments are transitioning from space system builders to space service buyers which structurally advantages nimble commercial providers]] — defense spending flows through commercial channels, accelerating the procurement transition
- [[the space economy reached 613 billion in 2024 and is converging on 1 trillion by 2032 making it a major global industry not a speculative frontier]] — defense is the fastest-growing demand driver within the $613B economy
- [[attractor states provide gravitational reference points for capital allocation during structural industry change]] — defense demand creates a secondary attractor pulling capital toward dual-use space companies
- [[SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages that no competitor can replicate piecemeal]] — defense contracts fund the cadence that feeds SpaceX's flywheel
