Quantum Computing Stock Has Tumbled This Year. Why Earnings Have the Market Excited. - Barron's

Quantum computing stocks have plummeted in 2025 amid broader tech sector volatility and delayed commercialization timelines, erasing gains from prior years’ hype-driven rallies. Upcoming earnings reports from key players like IBM, IonQ, and Rigetti are sparking optimism, with analysts anticipating breakthroughs in error correction and qubit stability to justify valuations. Investors are closely watching revenue growth from cloud-based quantum services and government contracts, particularly Defense Department and DOE funding tied to national security applications. Wall Street forecasts suggest a potential 20-30% rebound for top performers if earnings reveal progress in fault-tolerant systems or partnerships with Big Tech like Google and Microsoft. Short interest remains high, but options markets show rising call volume, signaling bettor confidence in a post-earnings rally despite lingering skepticism about near-term profitability.
