The Short Case for Quantum Computing Stocks Is Now Fully Loaded
The Setup
Four quantum computing pure-plays — D-Wave Quantum (QBTS), Rigetti Computing (RGTI), Quantum Computing Inc. (QUBT), and IonQ (IONQ) — closed Thursday’s session up 33%, 30%, 19%, and 12% respectively on a single catalyst: a Department of Commerce announcement of $2.013 billion in CHIPS Act letters of intent across nine quantum firms. QBTS and RGTI each received LOIs of up to $100 million. QUBT and IONQ received nothing. All four moved as a single basket.
This is the short - After the Euphoria Fades: Quantum Stocks Face a 25% Fall . A 30%-plus single-session move driven by a non-binding government document, in names already trading at 600x to 830x annualized revenue, heading into a three-day holiday weekend with no additional catalyst between now and Tuesday’s open. Each of the four arguments that drove the rally Thursday is wrong in a specific, documentable way. When retail sentiment is the only buyer left in thin pre-holiday volume, corrections in this basket are not gradual. They are fast and they are complete.
Argument One: The LOI Is Not Money
The market priced Thursday’s announcement as if QBTS and RGTI each received $100 million in cash. Neither did. A letter of intent under the CHIPS and Science Act is, by the Semiconductor Industry Association’s own definition, a non-binding agreement. It initiates a due diligence phase during which material facts are validated and risks are assessed before any final award agreement is reached. Cash disbursements begin only after final award documents are signed and only as project milestones are achieved — in tranches, not as a lump sum.
D-Wave’s own 8-K, filed the same day as the announcement, names five independent failure conditions in plain language: definitive award documents may not be executed within the contemplated timeframe or at all; the Department may suspend or terminate award negotiations; the Company may be unable to satisfy disbursement conditions including project milestones; appropriated funds may not be available; and existing shareholders face dilution from the equity issuance. Five veto points disclosed by the company on the day it called the LOI a landmark endorsement.
Rigetti’s filing adds the constraint the press coverage uniformly omitted: the $100 million is an award of up to that amount over three years. Annual cash impact at full close is approximately $33 million. Rigetti’s quarterly operating losses run multiples of that figure.
Argument Two: The Grant Structure Dilutes the Shareholders Who Just Rallied
The market treated the government equity stake as a cost attached to a cash grant. The actual structure inverts that reading entirely. D-Wave’s press release states it directly: in connection with executing final award documents, D-Wave would issue $100 million in shares of its common stock to the U.S. Department of Commerce. The government does not wire D-Wave cash and then accept equity as a fee. D-Wave issues new shares to the government in exchange for the R&D funding commitment. Existing shareholders are diluted. At Thursday’s closing price of approximately $25, the issuance would add roughly 4 million new shares to a 370 million share base — directly reducing the ownership stake of every shareholder who bought into the 33% move.
The shareholders who drove QBTS up 33% on Thursday did so in part to celebrate a transaction that will, if it closes, make their position worth less on a per-share basis. The net cash benefit to existing holders — after adjusting for dilution, a 60% close probability, three-year disbursement spread, and milestone risk — is approximately $50 to $90 million in fundamental market cap terms. The rally added $2.36 billion. The gap between those two numbers is the short.
Argument Three: The Trump Administration Has a Documented Pattern of Renegotiating CHIPS Act Awards
These are not Biden-era LOIs being honored reluctantly by a new administration. They were issued by the Trump Commerce Department on May 21. That fact reduces, but does not eliminate, the renegotiation risk. What it does not reduce is the execution risk embedded in every prior CHIPS Act award regardless of which administration issued it. Commerce Secretary Lutnick stated explicitly during a Senate hearing that some subsidies that had not been concluded were those that should never have been concluded. The administration’s stated philosophy is renegotiation toward better taxpayer terms, not rubber-stamping of prior commitments.
The quantum LOIs are fresher and politically aligned with the current administration’s technology priorities. But “letter of intent issued by a cooperative administration” is not the same as “money received.” The distance between those two points is where the short lives.
Argument Four: Nvidia Did Not Move
Nvidia runs CUDA-Q, an active quantum computing platform integrating GPU-accelerated simulation with hybrid quantum-classical workloads. It holds sector-wide partnerships, stages dedicated Quantum Day events, and is positioned as a primary infrastructure beneficiary of fault-tolerant quantum at commercial scale. If Thursday’s announcement represented a genuine inflection in quantum’s commercial timeline, Nvidia’s exposure to that inflection is real and its stock would have reflected it.
Nvidia reported a blowout quarter after Thursday’s bell — $81.6 billion in revenue, $75.2 billion from data centers alone, an $80 billion buyback. The stock fell. During the session itself, while QBTS rose 33%, Nvidia was flat. The market has demonstrated previously that it treats Jensen Huang’s view on quantum timelines as the authoritative signal: in January 2025, a single comment from Huang that practical quantum applications remained far away erased more than $5 billion in combined quantum market cap within days. His silence on Thursday — no revised quantum guidance, no press statement, no stock movement — is as informative as anything he has said directly. When the company best positioned to profit from quantum’s commercial arrival does not reprice on the sector’s largest single-day government endorsement in history, the pure-play moves are not a fundamental signal. They are a retail momentum event.
Argument Five: The Basket Has Done This Before, Recently
This is not a novel pattern. Three days before Thursday’s rally, on May 15, IONQ fell 7%, QBTS fell 8%, RGTI fell 9%, and QUBT fell 10% in a single session. No company-specific catalyst. Pure profit-taking after a preceding run. The same names, the same basket dynamic, the same sell sequence. That selloff followed a monthly gain in QUBT of approximately 45%. Thursday’s session added another 19% to QUBT on top of that. The basket is more extended now than it was before the May 15 correction, on a weaker catalyst — an LOI versus actual earnings beats.
The pattern in this group is consistent across 2025 and 2026: sharp basket rallies on sentiment catalysts followed by 6% to 10% corrections within two to three sessions as the catalyst is absorbed and profit-taking begins. Thursday’s move was three to five times larger than the typical sentiment spike. The correction, when it comes, will be proportional.
The Holiday Weekend as a Structural Accelerant
Today is the last trading session before Memorial Day. Markets are closed Monday. The next regular session is Tuesday, May 26. Institutional desks are already reduced. Bond markets close early. Volume in speculative names on the Friday before a long weekend is structurally thin — and thin volume in high-beta stocks with crowded retail positioning does not cushion corrections. It amplifies them.
Settlement mechanics add a further wrinkle. Friday stock trades before Memorial Day settle on Tuesday. Traders holding gains from Thursday’s spike are sitting on unsettled positions over a three-day weekend during which futures, oil prices, and overseas markets can reprice freely. Any adverse macro development — escalation in the Middle East, a sovereign credit event, a Fed communication — reaches these positions with no ability to exit until Tuesday’s open. The rational response to holding a 30% winner into a three-day weekend is to sell it on Friday. That selling pressure has no offset from institutional buyers who are not present.
Ranking the Short Targets
QUBT is the cleanest short. It received no grant, has the thinnest revenue base of the four — $3.69 million in Q1 2026 on a market cap that briefly exceeded $3 billion — trades at approximately 606x annualized revenue, and moved 19% on a catalyst that had nothing to do with its business. Its entire Thursday move was pure basket contagion. It has the least fundamental support and the most asymmetric downside.
QBTS is the second priority. The LOI is real but the economics, properly analyzed, add less than $90 million in fundamental value to a company whose market cap expanded by $2.36 billion in a single session. The equity swap structure means existing shareholders are celebrating a transaction that dilutes them. Operating losses ran $46.8 million in Q1 alone against $2.8 million in recognized revenue. The stock has the largest single-session gain to give back and the weakest near-term revenue trajectory in the group.
RGTI presents a similar structure to QBTS with the added constraint that its $100 million LOI is explicitly capped as an up-to figure spread over three years. The annual cash benefit at full close, probability-weighted, is approximately $20 million. The 30% single-session move on that figure is arithmetically unsupportable.
IONQ is the weakest short of the four and carries meaningful risk on the short side. It has the most defensible fundamental position — Q1 revenue of $64.7 million, up 755% year over year, with full-year guidance raised to $260 to $270 million. The SkyWater Technology acquisition expected to close in Q2 or Q3 represents a genuine near-term catalyst. Its Thursday move of 12% is closer to the justified range than the other three names, and it has actual revenue scale to absorb a re-rating. Shorting IONQ into a potential acquisition close announcement is a lower-probability trade.
The Position
The short case requires no macro deterioration, no earnings miss, and no exogenous shock. It requires only that the market finish reading what D-Wave disclosed in its own 8-K on the day it announced the LOI. The grant is non-binding, milestone-gated, spread across three years, paid in dilutive equity, subject to five named failure conditions, and benchmarked against a government that has publicly stated its willingness to renegotiate or abandon CHIPS Act commitments that do not meet its standards.
Nvidia, which has more to gain from quantum computing becoming real than any pure-play in the basket, was flat on Thursday. That is the entire argument in a single data point. When the infrastructure layer does not move on the sector’s biggest government endorsement in history, the pure-plays that moved 30% did not price new information. They priced a headline. Headlines correct. The 8-K is what remains.
