from the United States Court of Appeals for the Fifth Circuit.
Question presented
1. Whether a proposed submarket must be rejected if evidence shows that some customers can shift their purchases to other channels, even if other evidence establishes the unique competitive constraints that face another group of customers. 2. Whether a proposed submarket may be defined by sales that are made through an intermediary-controlled purchasing channel, when the market includes multiple suppliers and is not limited to a single brand or seller.

Briefing
What it's about
Endure Industries is asking the Supreme Court to review an antitrust fight over how to define the market for disposable medical supplies. The dispute is whether courts can treat sales through an intermediary-controlled purchasing channel as a narrower market when some buyers can shop elsewhere but other evidence points to distinct customers, prices, industry custom, and switching limits.
Argument
The case is pending on a petition for certiorari (the Court's decision to hear the case), and no oral argument is scheduled. Endure argues that courts should weigh practical evidence about a distinct purchasing channel even if some customers cross-shop.
Impact
Market definition often decides whether an antitrust case survives. Medical supply makers, hospitals, and purchasing intermediaries could be affected if courts make it easier or harder to treat a purchasing channel as its own market.
What is Endure v. Vizient about?
It asks whether antitrust law can recognize a narrower market for disposable medical supplies sold through an intermediary-controlled channel. The issue is whether some customer switching defeats that narrower market.
Who could be affected by Endure v. Vizient?
Medical supply makers, hospitals, and purchasing intermediaries could be affected. The answer could shape which sales and customers count when courts assess competition.
What happens next in Endure v. Vizient?
The Supreme Court must decide whether to hear the case. No oral argument is scheduled yet, and no decision window is available.
