DARPA Quietly Reopens Its Quantum Benchmarking Program to New Entrants, With Stage B Verdicts Still Pending

Quantum computing's listed pure-plays have just closed the busiest reporting stretch of their short public lives: IonQ on 5 August, Rigetti and D-Wave on 6 August, and Quantinuum — on Nasdaq under QNT only since its $1.68bn June IPO — on 11 August, alongside first figures from Europe's newly listed IQM. Largely unremarked, the federal programme most likely to decide which architectures survive has reopened its front door.

The Defense Advanced Research Projects Agency's Quantum Benchmarking Initiative is running a new Stage A topic call, catalogued as DARPA-PA-26-02-02. The contract-tracking service HigherGov records it as posted on 9 March 2026 and updated on 29 July, with the response deadline pushed back to 30 November 2026 from an original 30 September. The umbrella announcement, DARPA-PA-26-02, now closes on 30 December, extended from 14 November. HigherGov's algorithmic estimate of $1m to $5m for the topic is flagged as experimental and is not a DARPA-published figure. The call targets organisations new to QBI, though existing performers may bid where they offer new or distinct contributions.

QBI is not a procurement programme in the ordinary sense. DARPA's purpose is to test whether any approach to quantum computing can reach utility-scale operation — the point at which a machine is worth more than it costs to run — by 2033. It splits three ways: a six-month Stage A describing the concept, a year-long Stage B scrutinising the R&D plan, and a Stage C of real-time independent evaluation.

DARPA says it selected nearly 20 companies for Stage A, 17 of them announced. Its Stage B page names the 11 that advanced: Atom Computing, Diraq, IBM, IonQ, Nord Quantique, Photonic Inc., Quantinuum, Quantum Motion, QuEra Computing, Silicon Quantum Computing and Xanadu — a spread across neutral atoms, trapped ions, superconducting circuits, silicon spin qubits and photonics. Four are buyable on US exchanges: IBM, IonQ, Quantinuum since June, and Xanadu, on Nasdaq and Toronto as XNDU since 27 March 2026. The other seven are private.

The absences inform as much as the list. DARPA's own Stage A roster included Google Quantum AI and Rigetti Computing, neither of which appears in the Stage B cohort; the analysis site PostQuantum adds Hewlett Packard Enterprise. That is not rejection — PostQuantum notes further teams could join Stage B later, on staggered timelines, as contracts are finalised. Rigetti is not shut out of federal support regardless: its second-quarter release disclosed a Commerce Department letter of intent for up to $100m over three years.

The sums attached to QBI are modest. PostQuantum reports Stage B teams are eligible for up to $15m each over roughly 12 months — eligibility, not cash in hand. Rigetti, on Nasdaq as RGTI, reported second-quarter revenue of $5.1m, an operating loss of $28.1m and a GAAP net loss of $52.6m that includes a $29.6m non-cash charge for the change in fair value of warrant liabilities, with $541.3m in cash and investments at 30 June. IonQ, on the NYSE as IONQ, reported quarterly revenue of $80.1m, up 287% year on year, and an adjusted EBITDA loss of $120.3m. Its headline GAAP net loss of $1,867.7m is overwhelmingly an accounting event: roughly $1.65bn is a non-cash mark-to-market charge on warrant liabilities.

The largest cheque written under the programme so far has gone to a company public investors cannot buy. GovConWire reported that PsiQuantum finalised a $125m Stage C agreement with DARPA on 23 July 2026, following a $31.8m agreement in September 2025, covering testing of its software, system architecture, hardware design and cryogenic systems. Chief executive Victor Peng said: "DARPA's Quantum Benchmarking Initiative is one of the most comprehensive and rigorous government programs for evaluating emerging technology that I have ever seen." PsiQuantum is private.

QBI is not the only federal channel. On 21 May 2026 Commerce announced letters of intent worth $2.013bn across nine companies, per NIST: $1bn to IBM, $375m to GlobalFoundries, $100m each to Atom Computing, D-Wave, Infleqtion, PsiQuantum and Quantinuum, up to $100m to Rigetti and up to $38m to Diraq. Commerce said it will receive a minority, non-controlling equity stake in each company as a condition of the funds. Secretary Howard Lutnick said the investments "will build on our domestic industry, creating thousands of high-paying American jobs." A letter of intent is not disbursed money.

The commercial base underneath all this is thin. D-Wave, which moved its listing from the NYSE to Nasdaq on 27 July and still trades as QBTS, reported second-quarter revenue of $3.1m — flat year on year — and a GAAP net loss of $48m, narrowed from $167.3m as warrant remeasurement charges fell. First-half revenue was $5.9m, down 67% from $18.1m; first-half bookings of $35.5m rose more than 1,120%, and remaining performance obligations stood at $40.7m at 30 June. Bookings and RPO are contracted future work, not recognised revenue.

The newest listed name is IQM Quantum Computers, whose American depositary shares began trading on the Nasdaq Global Select Market as IQMX on 2 July 2026 after a business combination with Real Asset Acquisition Corp.; Helsinki trading followed a day later. IQM describes itself as the first European quantum computing company listed on a major US exchange. Its first results as a public company, in euros, showed first-half revenue of €8.9m against a first-half operating loss of €60.5m, with an order backlog — again, not revenue — of €102.1m at 3 August. IQM is not on DARPA's Stage B list.

The near-term calendar is unusually legible: PostQuantum expects Stage B evaluations to conclude by late 2026, the new Stage A call closes on 30 November and the umbrella announcement on 30 December. Whatever DARPA concludes will be the closest thing the industry has to an independent technical scorecard. It arrives after a round trip in the shares: in the month to 29 July IonQ was down 39% and Rigetti and D-Wave roughly 30% each, before all three rallied on their results, gaining roughly 7% to 12% in one session, per a 10 August TipRanks review. None has demonstrated a fault-tolerant, utility-scale machine.
