Bull case
▲ upsideHelios (Nov 2025) delivers 96 physical / 48 logical qubits at 99.99% SPAM — the highest fidelities in the industry. First public demonstration of universal fault-tolerant gate set. Backed by Honeywell, JPMorgan, Mitsui, NVIDIA. 2025 revenue $30.9M with FY26 acceleration claimed. Helios installed in Singapore March 2026 — first non-US deployment.
Bear case
▼ downsideQ1 2026 revenue dropped to $5.2M from $19.1M YoY; net loss widened to $136.6M. Roadmap claim of "universal fault-tolerant by 2030" is aggressive. IPO at $20B+ on $30.9M revenue = 650× sales — sets a fragile ceiling for the whole sector if it breaks.
