Rigetti Computing to Report Third Quarter 2026 Financial Results and Host Conference Call on November 10, 2026

Not IonQ. Not Rigetti Computing. This Quantum Computing Stock Is the One I'd Buy and Hold Through 2030.

While IonQ and Rigetti Computing are popular pure-play quantum computing stocks, both face significant challenges including operating losses, uncertain commercialization timelines, and shareholder dilution risks. Alphabet emerges as a superior quantum computing investment, leveraging its profitable core businesses to fund quantum research, including recent breakthroughs with its Willow quantum processor that achieved a 40x error reduction. Unlike smaller competitors, Alphabet can afford sustained experimentation while maintaining profitability and reasonable valuation.

IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. Are Shaking Wall Street to Its Core With This $1 Billion Warning

Despite impressive stock gains over two years, insiders at four major quantum computing companies have sold $1.02 billion in net shares since October 2021 while purchasing less than $4.3 million collectively. The lack of insider buying, combined with valuations exceeding 30x sales and historical precedent of tech bubbles, suggests investor caution may be warranted as quantum computing optimization could take years.

Shares of semiconductor and chip companies are trading lower as rising inflation concerns and elevated energy prices fuel expectations for further Fed rate hikes. Elevated borrowing costs could pressure semiconductor manufacturing and AI infrastructure investments while straining customer budgets. The Philadelphia Semiconductor Index (SOX) has declined for seven consecutive trading sessions, matching its longest losing streak since the 2008 financial crisis.
