Why I Wouldn't Touch IonQ, Even With Quantum Computing Stocks Soaring

IonQ (IONQ) shares trade near $39, with a market cap of $15B. Q2 2026 revenue was $80.1M, up 287% YoY. The company acquired SkyWater for $1.8B, with full-year revenue guidance of $280M-$290M. Despite growth, IonQ is unprofitable, with operating losses and a high share count. The stock trades at 57x trailing revenue, but could drop to 16-17x if revenue hits $900M. Integration challenges and industry uncertainty may keep the stock near current levels.

Quantum computing stocks like IonQ, Rigetti Computing, and D-Wave Quantum have fallen harder than the Nasdaq-100 during tech sector declines in 2026. These companies trade at high forward sales multiples, with IonQ at 52x, Rigetti at 223x, and D-Wave at 148.8x, despite reporting losses and relying on future growth. While their strong cash balances reduce near-term risks, their valuations remain vulnerable to further compression.

IonQ added Eric R. Ball and Timothy E. Baxter to its board, effective August 24, 2026. Both bring extensive experience in technology and finance to support IonQ's quantum growth strategy, particularly in hardware manufacturing and platform integration.

Insiders at IonQ, Rigetti, and D-Wave sold $863M more shares than they bought over three years, despite stock gains up to 6,200%. All three reported improved fundamentals in 2026, but trade at high price-to-sales ratios. Institutional investors show mixed interest in the sector.

IonQ completed its $1.8B acquisition of SkyWater Technology, creating a vertically integrated quantum platform. SkyWater generated $442M in 2025 revenue, with quantum services growing 30%. IonQ issued 24M shares and paid $741M in cash, diluting shares by 6-11.7%. The deal aims to accelerate IonQ's quantum hardware development, targeting 200,000 physical qubits by 2028. Combined revenue is expected to reach $800M annually.

IonQ reported $80.05 million in Q2 2026 revenue, up 287% YoY, and raised full-year 2026 guidance to $280-$290 million. The company acquired SkyWater Technology for $1.8 billion, creating a vertically integrated quantum computing platform. IonQ achieved 99.99% two-qubit gate fidelity, a industry first, driving commercial demand.
