Quantum Computing Stocks in 2026: What Q2 Earnings Changed for IonQ, Rigetti and D-Wave

The short answer

The three US-listed pure-play quantum computing stocks — IonQ (NYSE: IONQ), Rigetti Computing (Nasdaq: RGTI) and D-Wave Quantum (NYSE: QBTS) — reported second-quarter 2026 results on 5 and 6 August, and the sector rallied into the following session. The numbers justify the enthusiasm only in one place: commercial traction is real and accelerating, but it is still tiny relative to the market values attached to it. IonQ booked $80.1 million of revenue in a single quarter; Rigetti booked $5.1 million and lost $28.1 million at the operating line. Anyone buying this group is buying a roadmap, not a business.

What each company actually reported

All figures below come from the companies' own quarterly releases dated 5–6 August 2026, not from third-party summaries.

Company	Q2 2026 revenue	Balance sheet	Headline disclosure
IonQ (IONQ)	$80.1m, +287% YoY	~$3.0bn cash and investments	FY2026 guidance raised to $280–290m; remaining performance obligations +297% YoY; SkyWater and Nexus Photonics acquisitions closed
Rigetti (RGTI)	$5.1m	$541.3m cash and investments at 30 June	Operating loss $28.1m; GAAP net loss $52.6m ($0.16/share); HPE and Pittsburgh Supercomputing Center hybrid supercomputer collaboration
D-Wave (QBTS)	H1 bookings $35.5m, +1,120% YoY	H1 remaining performance obligations $40.7m, +668% YoY	Production QCaaS revenue reached 37.3% of total QCaaS revenue; named a Leader in the IDC MarketScape 2026 vendor assessment

Note the different units. IonQ reports quarterly GAAP revenue. D-Wave led with half-year bookings, which are signed commitments, not recognised revenue — a percentage change from a $2.9 million base produces a headline of 1,120% that says less than it appears to.

Our runway check — the number nobody quotes

For pre-profit hardware companies the question that matters is not this quarter's revenue, it is how many quarters of cash sit between today and the next dilutive equity raise. Dividing disclosed cash by the disclosed quarterly operating loss gives a crude but honest read:

Company	Cash disclosed	Quarterly operating loss	Implied quarters of runway
Rigetti	$541.3m	$28.1m	~19 quarters (≈4.7 years)
IonQ	~$3.0bn	Not disclosed in the release summary	Multi-year on any plausible burn
D-Wave	Not restated in the Q2 highlights	Not restated	Check the 10-Q before sizing a position

The conclusion is the opposite of the usual bear case. Solvency risk is not the near-term threat for IonQ or Rigetti at current burn rates; both have already raised into strength. The threat is that the runway gets spent on a roadmap that slips, and the shares de-rate long before the cash runs out.

How much of the move is already priced in

The rally has to be read against how far these names fell first. Between 1 June and 4 August 2026, IonQ dropped from $69.28 to $41.72, Rigetti from $25.63 to $17.45 and D-Wave from $29.18 to $21.83. The post-earnings bounce recovered part of a roughly 30–40% drawdown; it did not create a new high. Sell-side targets remain well above spot — D-Wave closed at $21.39 on 5 August against a consensus target near $37 — but consensus targets on pre-revenue technology have historically been an expression of narrative rather than a forecast.

Our scenario framework into year-end

Scenario	What has to happen	Our weighting
Bull	A credible commercial "quantum advantage" demonstration lands before December and IonQ delivers the top of its $290m guidance; the group re-tests the June highs	25%
Base	Revenue keeps compounding off a small base, no advantage milestone is validated, and the group trades in a wide range with headline-driven 10% days	55%
Bear	A roadmap slip, a guidance trim, or a rotation out of speculative tech; the June-to-August lows break and the drawdown extends	20%

What invalidates the base case: IonQ cutting or failing to reaffirm the $280–290m range at Q3, or D-Wave's bookings growth failing to convert into recognised revenue by year-end. Either would remove the only fundamental anchor the sector currently has.

What this means for traders

These are high-beta instruments, not investments in the conventional sense. Realised volatility puts single-session moves of 8–12% inside the normal range — Rigetti and D-Wave both moved that much on the earnings reaction alone. Three practical points:

• Position sizing does the work. A position sized for a 30% adverse move is the difference between participating in the theme and being forced out of it.
• Earnings dates are the volatility events. Quantum Computing Inc. (QUBT) had not yet reported when the other three did, leaving one scheduled catalyst still open in this cluster.
• The correlation is with risk appetite, not with quantum physics. These names trade with the speculative end of the AI complex; if you already hold the large-cap AI trade, this is not diversification. Our NVIDIA stock forecast and our note on getting exposure to private AI companies cover the same risk factor from the other side, and a diversified ETF core is what usually makes a speculative sleeve survivable.
