TLDR
- IonQ stock has climbed 678% over the past year with revenue guidance raised to $82-$100 million for 2025, up from $37.5 million in 2024
- Rigetti Computing shares surged 5,450% in 12 months after launching a 36-qubit system and securing a $35 million investment from Quanta Computer
- D-Wave Quantum jumped over 2,000% in the trailing year with 153 customers and $24 million in bookings, up 128% from the previous period
- The quantum computing market is projected to reach $170 billion by 2040 as companies develop systems for drug discovery, cryptography, and logistics
- All three stocks carry high price-to-sales ratios above 100x with continued operating losses as companies invest in research and development
Three quantum computing companies have posted extreme stock gains in 2025 as investors bet on the technology’s commercial future. IonQ, Rigetti Computing, and D-Wave Quantum have each seen their share prices multiply by factors of 6 to 54 over the past year.
The quantum computing market could grow to $170 billion by 2040 according to industry projections. These companies are developing systems that leverage qubits existing in multiple states simultaneously. The technology targets applications in drug discovery, cryptography, and optimization problems in logistics and finance.
All three companies currently operate at losses while building their technology and customer bases. They face competition from tech giants developing in-house quantum systems. Each company takes a different technical approach to quantum computing hardware.
IonQ Posts 678% Gain With Trapped-Ion Technology
IonQ trades at around $59 per share with a market cap near $20 billion. The company went public through a SPAC merger in 2021. Its trapped-ion quantum processors use electromagnetic fields to trap ytterbium ions for computations.
The company raised its 2025 revenue guidance to $82-$100 million. Third quarter revenue hit $12.4 million, up 102% year-over-year. IonQ sells quantum computing access through Amazon Web Services, Microsoft Azure, and Google Cloud.
The stock gained 77.9% year-to-date and 678% over 12 months. Amazon took a $36.7 million equity stake in the company. IonQ recently achieved 64 algorithmic qubits, which the company says enables 18 quintillion computational possibilities.
Eight analysts cover the stock with six Buy ratings and two Holds. The average price target sits at $64.57. B. Riley Securities analyst Craig Ellis maintains a $100 price target with a Buy rating.
IonQ holds $100 million in cash reserves. Operating losses reached $236 million in the first half of 2025 as the company scales operations. The trapped-ion approach offers longer coherence times compared to other quantum computing methods.
Rigetti Computing Launches 36-Qubit System
Rigetti Computing focuses on superconducting qubit technology. The Berkeley-based company went public in 2022. Its stock now trades around $39.60 per share.
Shares jumped 183.3% year-to-date and 5,450% over the past year. The stock surged 223% in the last 90 days alone. Rigetti launched a 36-qubit multi-chip system in August and plans to release a 100-qubit platform within six months.
The company sold two Novera 9-qubit systems for $5.7 million. Quanta Computer invested $35 million in April. Rigetti’s Ankaa-2 processor runs on Amazon Braket cloud platform.
Six analysts rate the stock a Buy with no Holds or Sells. Average price targets reach $30.25, ranging from $18 to $50. Benchmark analyst David Williams maintains a $50 price target with a Buy rating.
Revenue remains in the low millions per quarter. The company trades at 1,590 times sales. Operating losses rose 27% in the first half of 2025 as Rigetti scales production and develops new systems.
D-Wave Quantum Grows Customer Base to 153
D-Wave Quantum uses quantum annealing technology rather than gate-based systems. Founded in 1999, the company is the oldest of the three firms. The stock trades near $31 per share.
Shares gained over 2,000% in the trailing 12 months and 2,150% year-to-date. Six-month gains reached 387%. D-Wave ended 2024 with 153 customers and $24 million in bookings, up 128% from the prior year.
The company projects revenue growth from $9 million in 2024. D-Wave holds $819 million in cash. Its Advantage system runs on the Leap cloud platform and handles optimization problems for Volkswagen and Lockheed Martin.
Ten analysts give the stock a Buy rating with no Holds or Sells. Price targets average $20.50, ranging from $10 to $50. Roth Capital analyst Sujeeva De Silva raised the target to $50 after D-Wave announced a European deal.
D-Wave trades at 340 times sales. The company burns through cash at twice its revenue rate. The annealing approach targets specific optimization tasks rather than general computing applications.
Final Thoughts
All three companies trade at high valuations relative to current revenue as they invest in research and development. Wall Street analysts maintain Buy ratings across the sector as quantum computing technology moves toward commercial applications.
