A US appeals court denied a Federal Trade Commission bid to pause Microsoft Corp.’s acquisition of Activision Blizzard Inc. Friday, clearing a path for the companies to close the largest gaming deal ever in the US.

The 9th Circuit US Court of Appeals ruling means that only UK regulators stand between the companies closing the deal before a July 18 deadline. Britain’s antitrust appeals court has scheduled a hearing July 17 to discuss the companies’ request to pause the challenge to their deal by the country’s competition agency.

Activision climbed as much as 4.4% in after-hours trading, rising to $94 from its close of $90.07. Microsoft gained 1.5%.

The ruling is a blow to the FTC and its Chair Lina Khan, who sought to block the merger over concerns that Microsoft would withhold Activision’s most popular games from rival consoles or services. The court-ordered pause on Microsoft’s Activision merger expires at midnight Pacific time.

The UK Competition and Markets Authority, which vetoed the merger in April amid concerns over the deal’s impact on the cloud gaming market, has agreed to give Microsoft an unprecedented second chance to offer a remedy. Microsoft has offered to sell off the cloud-based market rights for games in the UK, Bloomberg earlier reported.

Company representatives didn’t immediately respond to a request for comment.

In a procedural move separate from this week’s developments, the CMA said Friday it had extended its deadline for issuing a legally final order on the deal until Aug. 29.
