Quantum computing is the ultimate long-duration bet. The physics works, commercial revenue is thin, and every pure-play player is burning cash toward a payoff years away. For a cautious investor, the question is who can actually pay for the trip. Cash on the balance sheet, quarterly operating burn, revenue traction, and access to further capital determine whether shareholders own a piece of the future or a diluted stub of it.
We ranked four pure-play quantum names on that scoreboard, counting down from the most fragile to the best funded.
4. D-Wave Quantum
D-Wave Quantum (NYSE:QBTS) has the shortest runway and the most acceleration in its burn. Q1 revenue landed at $2.86 million, down 81% year over year against a difficult prior-year comparison, while operating cash flow was negative $44.96 million and adjusted EBITDA loss widened to negative $32.8 million from negative $6.1 million a quarter earlier. Total cash of $588.4 million is respectable, but at this burn rate the runway shortens quickly. The bright spot: Q1 bookings of $33.4 million, roughly 2,000% higher year over year, and a $20 million Florida Atlantic University system deal plus a $10 million Fortune 100 QCaaS agreement. CEO Alan Baratz is spending to acquire optionality in the gate-model approach through the Quantum Circuits acquisition.
3. Quantum Computing
Quantum Computing (NASDAQ:QUBT) holds a fortress-level cash position by category standards: roughly $1.40 billion in total cash and investments following a $750 million private placement. Q1 revenue was $3.69 million, up from a trivial base, and the Q1 operating cash burn was only $9.42 million. On paper, that math offers years of runway. The catch is that cost of revenue of $4.41 million exceeded sales, producing a gross loss of $721,000, and most Q1 revenue came from the recently acquired Luminar Semiconductor and NuCrypt subsidiaries. CEO Yuping Huang is building a photonics platform anchored by Fab 1 in Tempe, Arizona. The cash is substantial, but the organic business is still forming.
2. Rigetti Computing
Rigetti Computing (NASDAQ:RGTI) wins on discipline. Q1 revenue nearly tripled to $4.4 million, and operating cash burn was just $16.22 million. Management describes a “Fortress balance sheet of $569 million in cash and investments with no debt.” That is the lowest burn-to-liquidity ratio in the peer set. CEO Subodh Kulkarni pushed the 108-qubit Cepheus-1-108Q system into general availability and is guiding to a 1,000-plus qubit machine by end of 2027, backed by a $100 million UK investment over three to four years. Rigetti can plausibly reach its next milestones without a dilutive capital raise.
1. IonQ
IonQ (NYSE:IONQ | IONQ Price Prediction) tops the scoreboard because it combines the deepest war chest with the strongest revenue trajectory. CFO Inder Singh told investors that “Cash, cash equivalents and investments as of March 31, 2026 were $3.1 billion.” Q1 revenue jumped to $64.67 million, up 755% year over year and 30% above the midpoint of guidance. Remaining performance obligations reached $470 million, up 554% year over year. Management raised full-year revenue guidance to $260 million–$270 million against an adjusted EBITDA loss of $310 million–$330 million. Q1 operating cash burn was heavy at negative $151.02 million, and FY2025 financing inflows totaled $3.36 billion. With revenue doubling organically and the pending SkyWater Technology acquisition adding U.S. manufacturing capacity, CEO Niccolo de Masi has more room to fund the roadmap than any peer.
Insider behavior deserves a caveat. During June, de Masi disposed of 16,120 shares at $56.2052 alongside selling by the CFO and other executives; there were zero open-market purchases across the four-month window. Retail sentiment on Reddit also shifted, most recently registering bullish at a score of 76 on June 30, with the shares closing at $53.26, down 26.1% over the past month.
The Scoreboard Verdict
Revenue is thin across the entire pure-play quantum group, and every name here funds itself with investor capital. Ranked on runway and revenue traction, IonQ is the only company with both a multi-billion-dollar cash cushion and revenue growing fast enough to matter, which is why it wins the scoreboard even after a brutal month for the stock.
Rigetti earns its rank by spending carefully. D-Wave and Quantum Computing occupy opposite extremes: one burning through a smaller cash pile too quickly, the other sitting on a large pile it has not yet learned to convert into revenue.
The practical takeaway is simple. The path forward is expensive, and only one of these four companies is currently funding it through operating momentum rather than pure dilution.
