Viasat jumped 17.1% on Space Force protected-SATCOM wins and doubled analyst targets, leading an optical-terminal and ground-segment rally — Telesat +10%, MDA +8.4%, SES +12.9% — as the SpaceX-proxy fund lagged.

Viasat (VSAT) led the space basket on Tuesday, up 17.1% to $89.81, extending a multi-day repricing on the optical-terminals and ground-segment chokepoints. The catalysts are concrete: the US Space Force selected Viasat to build, launch and deliver the first of a fleet of maneuverable GEO satellites under the Protected Tactical SATCOM-Global program, part of a $437.7M award for the first two operational PTS-G anti-jam birds — and Wall Street reset to it, with Oppenheimer initiating at Outperform with a $140 target and Deutsche Bank and Needham both more than doubling prior targets into the $90s. Viasat's edge here is spectrum and the anti-jam ground-and-space terminal layer, the chokepoint through which protected military connectivity has to pass.

Destiny Tech100 (DXYZ) was the laggard, down 1.7% to $25.76, but the signal is thin — it is a closed-end fund whose price swings on premium-and-discount noise around a private book (SpaceX is its largest position), not on an operating catalyst. On a day the tradable, contract-driven space names ripped, the illiquid private-exposure vehicle drifted the other way, a technical quirk rather than a read on launch economics.

The optical inter-satellite-link chain was the session's real theme. Telesat (TSAT) rose 10.0% to $50.62 — its Lightspeed LEO constellation carries four 10Gbps optical crosslinks per satellite — and MDA Space (MDA), the Lightspeed prime that placed the 792-terminal order with Tesat, gained 8.4% to $41.28, tying the in-space-infrastructure and optical-terminal chokepoints together. Ground-segment operator SES's OTC line (SGBAF) jumped 12.9% to $8.47, and the rad-hard and PNT names firmed — Mercury Systems (MRCY) +11.0% to $122.33 on rad-tolerant space data hardware, Frequency Electronics (FEIM) +7.4% to $66.35 on atomic clocks, and Karman (KRMN) +6.0% to $49.92. The laggards were minor: BlackSky (BKSY) −1.5% and Umicore's line (UMICY) −1.3%.

The catalyst calendar builds through the summer. L3Harris reports Q2 on July 23 and Iridium on July 24, with Iridium's PNT ASIC commercial availability targeted around July 31 for the resilient-navigation chokepoint. Firefly Aerospace's Q2 lands August 4, Rocket Lab's on August 6 — its first full quarter owning the Mynaric optical-terminal assets — AST SpaceMobile on August 10, and Viasat's own fiscal-Q1 print around August 12, the first read on whether the PTS-G momentum flows through to backlog.
