Helios (Nov 2025): 98 physical qubits, 50 logical qubits, 99.9975% 1Q and 99.921% 2Q gate fidelity. All-to-all qubit connectivity. Quantum Volume 33,554,432 (2^25, Sept 2025). Microsoft partnership (2024): demonstrated 4 logical qubits across 14,000 experiments without a single error. H2 (56 qubits) achieved QV 1,048,576 (2^20) in 2024. Software: InQuanto (quantum chemistry), Quantum Origin (cybersecurity entropy source), and lambeq (quantum NLP/AI). In September 2026, Quantinuum validated its Helix error-correction architecture on Helios: logical memory, logical Clifford computation, and logical entanglement across different codes each outperformed the corresponding physical-level result without post-selection, providing the stated architectural foundation for Apollo.

Generated from live analyst targets, SEC filings and market data as of September 2026 — not investment advice.
▲ THE BULL CASE
• Wall Street's mean price target of $97.17 implies 87% upside — consensus rating Buy across 12 analysts.
• 12 of 13 analyst ratings are Buy or Strong Buy.
• Revenue grew 35% year-over-year to $30.93M (latest fiscal year).
• $2.11B in cash gives roughly 113 months of runway at the current burn rate.
• $3.98M in U.S. federal contracts and grants across 1 awards validates the technology with government customers.
▼ THE BEAR CASE
• 70.1% of daily trading volume is short selling (FINRA), signaling heavy bearish positioning.
• Not yet profitable: net loss of $192.56M in the latest fiscal year.
• The stock is down 14% over the past year.
Quantinuum has roughly 113 months of cash runway as of September 2026 — $2.11B in cash divided by its trailing-twelve-month operating burn.
Quantinuum has received $3.98M in U.S. federal contracts and grants across 1 tracked awards (USAspending.gov).
Dilution risk looks moderate right now: no active going-concern flag and roughly 113 months of runway, with no ATM offering filings tracked.
Quantinuum's Helios has 98 physical qubits and is available now; its roadmap targets Sol next-generation system 2027; Apollo universal fault-tolerant system 2029; commercial quantum advantage by 2027.
70.1% of QNT's daily trading volume was short selling as of 2026-09-16 (FINRA daily short volume).
