WisdomTree Classiq Quantum Computing Index May 2026 rebalance. D-Wave, IonQ, Rigetti at 5.45 percent each. Infleqtion and Xanadu at 2.93 percent.

WisdomTree published analysis of its Classiq Quantum Computing Index May 2026 quarterly rebalance. D-Wave, IonQ, and Rigetti remain the largest pure-play positions at 5.45 percent each. Quantum Computing Inc sits at 3.57 percent. Infleqtion and Xanadu are each at 2.93 percent.

The analysis notes that pure-play quantum companies give investors direct sensitivity to the theme but with significant volatility. Revenue visibility is limited, operating losses are common, and market prices move on technical milestones rather than conventional earnings progression. The index approach spreads exposure across multiple qubit modalities rather than concentrating on one architecture.

Equal weighting across D-Wave, IonQ, and Rigetti despite their very different technical and commercial profiles is the ETF approach to uncertainty about which architecture wins. Reasonable given the current state of the field

Xanadu at 2.93 percent is the photonic quantum bet. PsiQuantum is private so Xanadu is the only listed photonic exposure in most quantum indices. That architecture has had significant research momentum this year

The multiple qubit modalities framing is the right investment thesis. Superconducting, trapped ion, neutral atom, photonic, and annealing all have different advantage profiles for different problems. None has won definitively

Market prices moving on technical milestones rather than earnings is the honest description of quantum investing in 2026. That is a feature not a bug if you believe the milestones are genuine indicators of eventual commercial value

[Piston]

The index giving investors exposure to the theme without requiring them to pick the winner is the pragmatic approach for anyone who wants quantum in a portfolio without deep technical knowledge
