Will the US Hold Rigetti Equity Before 2027? Markets Say 84%

Rigetti Computing Jumps to 84% on US Equity Stake Market, But a Letter of Intent Isn't a Signature

The U.S. Department of Commerce announced on May 21 that it had signed letters of intent with nine quantum computing companies for a combined $2 billion in CHIPS and Science Act funding. Rigetti Computing is slated to receive up to $100 million over three years, with the government obtaining a minority, non-controlling equity stake in return. Rigetti's stock surged roughly 23% on the news, closing at $26.42 after opening at $22.96 on May 22.

Prediction markets moved even faster. On the "Which companies will the US take a stake in before 2027?" contract, Rigetti's implied probability vaulted from 18% to 84% in three days, a 66-percentage-point swing. Kalshi prices the outcome at 81%; Polymarket sits at 87%. Both platforms are treating a letter of intent as near-certainty that the federal government will hold equity in Rigetti before December 31, 2026. The gap between that confidence and the legal reality of what exists on paper is where the risk lives.

Letters of intent are non-binding expressions of negotiating intent. They precede due diligence, final term sheets, regulatory review, and executed agreements. The market has priced 84% on a document that carries no legal obligation to close.

What the CHIPS Act Announcement Actually Says About a US Stake in Rigetti

The NIST press release uses careful language. The Department of Commerce "announced the signing of 9 letters of intent to provide $2.013 billion in federal incentives." The operative phrase is "letters of intent," not "agreements," "contracts," or "executed equity transactions." The funding is conditional: Rigetti must satisfy whatever terms Commerce negotiates before any money flows or equity changes hands.

The CHIPS Act framework for semiconductor and quantum computing investments has historically required companies to meet milestones related to domestic manufacturing, workforce development, and technology transfer. For Rigetti, a company that reported just $4.4 million in Q1 2026 revenue against a $26 million operating loss and $33.1 million net loss, the negotiation around equity terms could be contentious. The government will want favorable conversion terms; Rigetti's board will want to minimize dilution for a company with a $7.32 billion market cap.

What the announcement confirms: Commerce wants to invest in Rigetti. What it does not confirm: the final equity percentage, the valuation basis, the closing timeline, or whether the deal survives negotiation. Every one of those unknowns sits between today's 84% implied probability and resolution.

The 2026 Deadline Is Doing Real Work: Timeline Risk for Rigetti

This market resolves by December 31, 2026. That gives the Department of Commerce roughly seven months to convert a letter of intent into a finalized equity stake. Government procurement and investment timelines routinely stretch well beyond that window. The CHIPS Act's semiconductor fabrication grants, announced in preliminary form throughout 2024, took 12 to 18 months to reach binding agreements in many cases. Quantum computing investments add complexity: the technology is pre-commercial, valuation benchmarks are scarce, and the equity-for-funding mechanism is relatively novel for Commerce.

Rigetti has some incentive to move quickly. The company is burning cash at a rate of roughly $33 million per quarter and holds $569 million in reserves. A $100 million infusion, even spread over three years, would extend its runway and validate its technology in the eyes of institutional investors. But Rigetti is also committing up to $100 million to a UK quantum computing deployment, which could complicate negotiations if Commerce attaches domestic-priority conditions to the funding.

The period from LOI to close is not a formality. It is where deals die, stall, or get restructured. Seven months is tight for a federal equity transaction in an emerging technology sector, and the market is offering only 16 percentage points of downside protection for that risk.

The Strongest Case Against Rigetti Computing Hitting 84%

The bear case rests on three pillars, none of which require Rigetti to lose the deal entirely.

First, timing. If Commerce finalizes the equity stake on January 15, 2027, the market resolves NO despite the deal being real. The resolution condition is binary and date-bound. An 84% price implies the market assigns only a 16% chance of the close date slipping past year-end, a remarkably thin margin for a federal bureaucratic process that has no publicly stated deadline.

Second, negotiation risk. Rigetti's Q1 financials show $4.4 million in quarterly revenue against a $7.32 billion market cap. The government's equity valuation methodology could produce terms Rigetti's board finds unacceptable. A renegotiation cycle would consume months. Letters of intent collapse regularly in private markets; there is no reason to assume government LOIs are more durable.

Third, political and appropriations risk. CHIPS Act funding requires ongoing congressional support for disbursement. Any budgetary disruption, continuing resolution, or policy shift in the remaining months of 2026 could delay or suspend the program. The $2 billion quantum initiative is large enough to attract scrutiny, and Rigetti is small enough to be deprioritized if the program faces cuts.

The 6-percentage-point spread between Kalshi (81%) and Polymarket (87%) suggests the platforms' trader bases have slightly different assessments of these risks. Polymarket's higher price may reflect a more aggressive interpretation of the LOI as a near-guarantee. Kalshi's lower price leaves marginally more room for timeline slippage.

At 84%, the market is pricing a letter of intent as though it were a closing document. The most likely outcome may still be YES, but the probability should reflect the distance between intent and execution, not just the direction of travel. Traders buying at current levels are accepting meaningful deadline risk for a thin premium.
