K2 Space designs and manufactures large satellite buses, including its Mega and planned Giga lines, for government and commercial spacecraft customers.
Darker bar: ahead of the other company on that measure.
K2 Space is a US satellite maker executing a bigger-is-better thesis (its Gravitas demonstrator launched March 2026 with claimed most-powerful Hall thrusters in space, plus Mega- and 100kW Giga-class buses) from a Torrance factory designed for up to 100 large satellites a year. It has converted to anchor contracts: an SES initial tranche of 30 MEO satellites (its largest disclosed commercial win), buses for Anduril in the Golden Dome interceptor program, and a Space Force Protected Tactical Satcom bus role. It raised >$1B (a Series D in July 2026 at $6.8B, 2.3x in seven months) with >$1B in signed contracts; recognized revenue is estimated at 10-100m.

The company sells Nyx reusable cargo capsules for commercial and institutional orbital logistics, including cargo transport to and return from the ISS.
Darker bar: ahead of the other company on that measure.
TEC is building reusable orbital cargo capsules sold as a delivery-and-return service, and in September 2026 it became the first European company to win a capsule transportation service contract from ESA in open competition. The ALADDIN Phase 2 contract, signed 2026-09-10 at the International Space Summit in Paris, totals EUR 760 million: EUR 310 million for an initial Nyx demonstration mission to the ISS and EUR 450 million for two optional additional missions. The structure is the interesting part: TEC had to demonstrate technical readiness milestones and secure 40 percent of the demonstration financing privately, with ESA covering 60 percent, pushing Europe toward a NASA-style anchor-customer model. It closed a USD 450 million Series C the same week, taking total funding since 2021 to roughly USD 680 million, and agreed with Arianespace to launch the first Nyx demonstration on Ariane 6. The technology score is held at 3 deliberately. Mission Bikini launched on the maiden Ariane 6 flight in July 2024 but an upper-stage anomaly left it stranded. Mission Possible launched 2025-06-23 on Falcon 9 Transporter-14, powered 25 payloads, held attitude control, re-entered in controlled fashion from 550 kilometres and re-established communications after blackout, then lost contact at 26 kilometres just before parachute deployment and was lost before splashdown. End-to-end reentry and recovery has still never been demonstrated, the gating risk on the whole Nyx business case.
