A U.S. grant for domestic gallium-arsenide production lifted 5N Plus while rate-sensitive satellite operators sold off.

The space basket's leader owned the materials chokepoint. 5N Plus (FPLSF) rose 5.1% to $19.25 after being selected for roughly US$7.3 million in U.S. government funding to establish domestic production of gallium-arsenide electro-optical components at its St. George, Utah facility, with a sell-side desk reiterating a Buy and a $44 target. This is the III-V materials strait — the germanium and gallium-arsenide substrates behind space-grade solar cells, infrared optics, and radiation-hardened detectors — and Washington paying to onshore it is exactly the kind of policy tailwind that reprices a supplier when China holds the export controls. It bucked a broadly red tape: the indices fell for a fourth straight day, WTI cleared $100, and Fed funds futures priced roughly a 73% chance of a rate hike next week.

The laggard was the small-sat operating layer. Satellogic (SATL) fell 5.8% to $4.70, the steepest decline in the basket — a thin line, but part of a clear sell in rate-sensitive, pre-scale space names: AST SpaceMobile (ASTS) −4.0% to $59.91, BlackSky (BKSY) −4.0% to $20.75, and Planet Labs (PL) −3.1% to $16.69. These are the constellation-and-downlink businesses whose value sits years out in deployed capacity, and a higher-rate, higher-oil session discounts that horizon first. No company-specific break drove it; it was duration being marked down.

The split by revenue model was sharp. The funded comms-and-integration end held up: Viasat (VSAT) rose 2.5% to $74.18, CACI International (CACI) gained 2.8% to $624.01, SiTime (SITM) added 2.1%, and Redwire (RDW) rose 1.6%. The read is the same one running across the hard-tech verticals today — the market rewarded contracted, near-cash-flow names and the onshoring-of-materials trade, and cut the speculative capacity builders.

The calendar is dense and immediate. Planet Labs reports Q2 FY2027 on September 14, a direct test of the earth-observation demand the tape just marked down, and Astroscale's APS-R Space Force refueler is set to launch to GEO around September 15. Satellogic's first AI-first constellation satellite is targeted for October 31 — the deployment its own selloff was pricing against. Further out, China's suspension of the germanium/gallium export ban expires November 27, the date that bears directly on 5N Plus's onshoring thesis, and SpaceX's post-IPO lock-up fully expires December 9.
