Quantum Computing Market Poised for $850 Billion Growth by 2040 as Commercial Use Expands

The quantum computing industry is undergoing a radical shift toward commercial applications, with McKinsey projecting the global market to reach $850 billion by 2040. However, some sector participants are facing severe headwinds, as D-Wave Quantum Inc. (QBTS) shares have lost more than half of their value year-to-date in 2026. The QBTS stock recently broke below the $14 threshold, hitting its lowest level since May 2025, highlighting a stark performance gap compared to industry leaders like IBM and Google. This downturn coincides with Rigetti Computing reporting technical improvements that analysts still view as lagging behind established industry benchmarks. Despite these individual stock volatilities, investor interest remains focused on specialized ETFs like QTUM and SOXX to capture broader sector growth. Quantum computing remains positioned as the next major investment cycle, even as financial performance diverges significantly among market players.
