Antitrust Law Daily Wrap Up, ACQUISITIONS & MERGERS NEWS: FTC clears IonQ-SkyWater merger after deadlocked commission declines behavioral remedy, (Aug 4, 2026)

By Wendy Biddle, J.D.

The Commission granted early termination of its HSR review of a vertical merger in the nascent quantum computing sector.

The Federal Trade Commission announced that it has terminated its antitrust review of IonQ, Inc.'s proposed acquisition of SkyWater Technology, Inc. on July 28, 2026, clearing the path for a vertical merger that drew split views within the Commission, not on whether competitive concerns existed, but on whether those concerns were substantial enough to justify a behavioral remedy. Chairman Andrew N. Ferguson, who favored a consent order, and Commissioner Mark R. Meador, who concluded the record did not support even that intervention, each issued written statements on July 31 explaining their respective reasoning.

Background. IonQ is a quantum computing company engaged in the highly competitive race to develop the first fault-tolerant quantum computer. SkyWater is a U.S.-based semiconductor foundry providing chip fabrication and development services to multiple quantum computing firms, including IonQ and several of its direct competitors. Because SkyWater's customers pursue distinct technological approaches (superconducting, trapped ion, photonic, neutral atom, and topological platforms) each engagement involves highly customized chip development tailored to a specific firm's research architecture.

IonQ announced the acquisition in January 2026, publicly representing that the deal would accelerate its research and development by enabling closer collaboration with its manufacturing partner. The transaction is a vertical merger, combining firms at different levels of the same supply chain: IonQ as a downstream quantum computing developer and SkyWater as an upstream foundry supplier.

The Commission opened a pre-filing investigation and, following that investigation, reached early termination on July 28, 2026. The Chairman and Commissioner Meador agreed that a lawsuit to enjoin the merger outright would be an imprudent use of agency resources. They disagreed on whether to impose a consent order as a condition of clearance.

Chairman Ferguson's reasoning. Chairman Ferguson concluded that the staff investigation gave him sufficient reason to believe the merger may substantially lessen competition in the short term, even while likely generating pro-competitive efficiencies over time. He identified two textbook vertical merger concerns.

First, post-merger IonQ would have both the ability and incentive to foreclose rivals' access to SkyWater's foundry services. Switching foundries is expensive and time-consuming under ordinary circumstances; in the experimental quantum computing sector, a forced transition could add months of delay to competitors' projects. Even if alternative foundries exist, the disruption itself could be competitively significant, particularly because the race for fault-tolerant quantum computing is intensely time-sensitive.

Second, the acquisition would give IonQ access to the competitively sensitive technical information that SkyWater holds on behalf of its other customers, potentially chilling future investment and cooperation with SkyWater by those rivals.

Ferguson characterized these risks as acute in the near term but limited in duration. He noted that the federal government's investment of approximately $2 billion through the CHIPS Act in domestic quantum foundry capacity—including funding for two new domestic foundries—would, once those facilities come online over the next several years, provide competitors with viable alternatives. The long-term risk to competition was therefore low, he concluded, and the case called for a targeted behavioral remedy rather than either a full block or unconditional clearance.

The proposed consent order Ferguson supported would have required the merged firm to maintain non-discrimination rules guaranteeing rivals fair access to SkyWater's services; information firewalls separating employees working on IonQ's projects from those working on competitors' projects; transition assistance for customers seeking to switch foundries; a fast-track arbitration mechanism for disputes; a compliance monitor; whistleblower protections; and advance notice to the Commission before acquiring another foundry. He viewed this order as protecting the Trump Administration's quantum investments by ensuring rivals could continue development while new domestic foundry capacity came online.

Ferguson acknowledged the difficulty of vertical merger litigation, noting that since 2017 the federal government has brought five such cases and prevailed in only one. He concluded that a behavioral remedy represented the most procompetitive option available and that the Commission had an obligation to use it rather than choose between impractical litigation and doing nothing.

Commissioner Meador's reasoning. Commissioner Meador agreed with Ferguson that the transaction raised vertical foreclosure concerns warranting investigation, and he also agreed that an outright block was unwarranted. He parted from the Chairman, however, by concluding that the evidentiary record did not support even a behavioral remedy, because the evidence failed to establish that the merger may substantially lessen competition.

Meador organized his analysis around four factors. First, on foreclosure share, he found that the hypothetical foreclosure concern was limited to SkyWater's existing customer base, reported as eight customers at the end of 2025. This figure represented only a small fraction of the 50 percent share the 2023 Merger Guidelines identify as presumptively substantial, and fell well below the 30 to 40 percent threshold courts have applied in exclusive dealing cases.

Second, Meador found insufficient evidence that SkyWater constitutes a "must have" input. The U.S. quantum computing industry is populated by dozens of firms across multiple hardware modalities, supported by a wide range of domestic and international foundries, including national laboratory facilities at Sandia, Berkeley, Argonne, and SLAC, as well as a forthcoming NSF National Quantum Nanofab. In that environment, he concluded, quantum computing firms are not functionally required to use any single fabrication supplier.

Third, consistent with the Chairman's own analysis, Meador noted that any potential foreclosure harm was short-term in nature, a factor he viewed not as a basis for a remedy, but as an indication that the concern was too narrow, speculative, and transient to justify regulatory intervention. He emphasized that the industry's highly specialized contracting relationships allow customers to protect their own interests through ordinary commercial arrangements.

Fourth, Meador pointed to the federal government's substantial and accelerating investment in domestic quantum manufacturing as further evidence that competitive conditions in the sector are reinforced rather than fragile. He cited the Department of Commerce's May 2026 announcement of $2.013 billion in CHIPS Act incentives to nine quantum companies, including two domestic foundries; two executive orders issued in June 2026 directing agencies to expand domestic quantum supply chains; and the July 2026 Genesis Mission committing more than $5 billion to AI-enabled scientific discovery and quantum fabrication infrastructure. In light of these conditions, Meador concluded that IonQ's incentives appear aligned with maintaining SkyWater as a neutral, multi-customer foundry rather than restricting access.

Meador also noted that many quantum computing firms already pursue parallel development paths across different architectures and work with multiple fabricators simultaneously, further reducing dependence on any single foundry relationship.

Outcome. With the Commission equally divided on the consent order, and both commissioners agreeing that full litigation was unwarranted, early termination was granted on July 28, 2026. The merger may proceed without conditions. Chairman Ferguson noted that the Commission will continue to monitor the quantum computing industry for competitive threats, including from the merged firm.
