What it is
Microsoft Publisher Content Marketplace connects premium articles from launch partners into Copilot, MSN, and Microsoft Discover, with Microsoft matching user demand to licensed publisher supply. It turns publisher licensing into a retrieval-time market rather than a pure bot-blocking or standards effort.
Limitations
Microsoft Publisher Content Marketplace is a closed distribution marketplace inside Microsoft's own surfaces rather than a reusable web standard or neutral exchange.
