Which open mapping project supplies map data for Snap Map?

The open mapping project that supplies map data for Snap Map is OpenStreetMap.

OpenStreetMap, often abbreviated OSM, is a collaborative geographic database built from contributions by people, organizations and other data sources. Its openly licensed map information can describe roads, buildings, places, boundaries and other geographic features.

Snap Map uses third-party mapping technology and data rather than relying on a completely independent Snapchat map database. Snap’s published licensing information identifies OpenStreetMap contributors among the sources for map data, while other providers may supply imagery, building information or additional geographic layers.

A common mix-up is confusing the data project with a consumer mapping app. Google Maps, Apple Maps and HERE WeGo are end-user mapping services, whereas OpenStreetMap is an editable open geographic-data project. Mapbox may also be mentioned in connection with Snap Map because it provides mapping tools and services, but the open project named in the question is OpenStreetMap.
