The global quantum computing market is estimated at $1.44 billion in 2025 and could reach $19.44 billion by 2035, representing an average annual growth rate of approximately 30%. Three options are available to investors: large-cap tech companies such as IBM, Alphabet, Microsoft, and Amazon, specialized pure players like IonQ, Rigetti Computing, and D-Wave Quantum, and thematic ETFs such as Defiance Quantum ETF (QTUM) and WisdomTree Quantum Computing Fund (WQTM).

ETFs allow investors to smooth the sector’s inherent volatility while benefiting from its potential long-term growth.
