Reasoning
The upside is a non-linear regulatory/operations inflection: once aircraft are certified and the first city networks run safely at high utilization, value migrates from prototype progress to measurable throughput and recurring service attach (operations, maintenance, software, infrastructure participation). Archer’s unusually strong liquidity and partner graph reduce existential risk and can accelerate city-by-city replication, while defense/powertrain programs de-binary the passenger timeline.
