D-Wave Quantum vs. Rigetti Computing: Which Quantum Computing Stock Is a Better Buy in 2026?

The article pits D-Wave (QBTS) vs Rigetti (RGTI) as quantum opportunities for the next decade, highlighting that D-Wave’s FY2025 revenue rose 178.5% to $24.6M but it still posted a $355.1M net loss and -$75.8M free cash flow. Rigetti’s FY2025 revenue fell 34.3% to $7.1M with a $216.2M net loss and -$77.2M free cash flow, while facing customer concentration tied to government contracts. Despite both remaining loss-making, the author’s conclusion favors D-Wave, citing its acquisition adding gate-model capabilities and reporting $100M in U.S. government funding (Rigetti not awarded).

Analysis

The market is still pricing quantum as a narrative asset, not a discounted cash-flow business. In that regime, the real winners are the firms with durable funding sources and lower dilution risk, not necessarily the best hardware roadmap; that argues for IBM as the cleaner way to own the theme, while the pure-plays remain financing trades more than operating businesses.

Relative losers are the names with weak revenue visibility and customer concentration, because any delay in commercialization forces equity issuance to bridge burn. For RGTI, the hidden risk is not just execution on architecture, but that government procurement timing can create quarters of apparent momentum followed by long air pockets; that pattern tends to compress multiples once the next raise comes into view. QBTS has better near-term optionality from broader platform positioning, but the market is already paying for a multi-year victory lap before proof of durable enterprise conversion.

Contrarian view: the consensus is over-weighting technical superiority and under-weighting survivability. In speculative hardware, the first-order question is who can stay alive long enough to benefit from the eventual market; that makes balance-sheet endurance, contract mix, and share count trajectory more important than press-release progress. Over 1-3 months, expect headline-driven spikes; over 6-18 months, the key falsifier is whether revenue can inflect without a corresponding acceleration in cash burn or dilution.

Key Decisions for Investors

• Prefer IBM as the lower-beta way to express quantum optionality over 3-12 months; it has operating earnings and can absorb R&D without binary financing risk. Falsifier: if IBM’s quantum messaging stops supporting enterprise pipeline or the stock rerates sharply on other core-business issues.
• Short RGTI on strength or via put spreads after retail-led spikes; the setup is most vulnerable into any gap-up that is not backed by backlog or customer conversion. Cover if a material new government award or multi-quarter revenue acceleration emerges over the next 1-2 quarters.
• If holding a speculative quantum exposure, favor QBTS over RGTI only as a tactical relative-value long on pullbacks, not as a core position. Require evidence of enterprise adoption and controlled dilution; exit if cash burn persists while the share count rises.
• Use a basket hedge: long IBM / short RGTI for a 3-6 month relative-value expression. The trade works if quantum enthusiasm fades and investors rotate toward credible incumbents; invalidate it if RGTI lands a step-change contract or financing on favorable terms.
