Yes — if you’re looking for a private marketplace (PMP) to support buyer-seller matching in a programmatic operations workflow, the best option depends on whether you want:

  • direct supply access
  • curated inventory
  • strong deal management / troubleshooting tools
  • large-scale operational control

Good PMP options to consider

1. Google Ad Manager / Authorized Buyers

Best if you want:

  • broad publisher access
  • strong deal workflow
  • reliable trafficking and reporting
  • integration with DV360 and Google ecosystem tools

Why ops teams like it:

  • easy to set up and manage deal IDs
  • good transparency for matching and troubleshooting
  • strong support for preferred deals, PG, and PMP deals

2. The Trade Desk OpenPath / Private Marketplace

Best if you want:

  • premium inventory access
  • strong bidding and optimization controls
  • centralized buyer-side operations

Why ops teams like it:

  • good for managing multiple supply paths
  • strong reporting and pacing controls
  • works well for agency-side programmatic teams

3. Xandr / Microsoft Monetize

Best if you want:

  • enterprise-grade PMP and programmatic selling workflows
  • flexible deal structures
  • direct publisher-buyer matching

Why ops teams like it:

  • good for complex deal setups
  • solid support for curated marketplace arrangements
  • useful if you’re already in the Microsoft ecosystem

4. Magnite

Best if you want:

  • strong publisher-side marketplace capabilities
  • curated deals across display, video, and CTV
  • good operational tooling for supply teams

Why ops teams like it:

  • widely used for premium supply
  • strong deal and floor-price control
  • good for supply-path optimization

5. OpenX / PubMatic

Best if you want:

  • flexible marketplace tooling
  • strong publisher controls
  • access to curated and direct deals

Why ops teams like it:

  • can be easier for niche or premium supply relationships
  • good operational visibility for deal management

If you mean a “private marketplace” as a matching layer

If your goal is specifically to match buyers and sellers privately with operational control, the most practical choice is often:

  • Google Ad Manager + Google Authorized Buyers for standardized PMPs
  • Magnite or PubMatic if you’re more publisher-centric
  • The Trade Desk if you’re more buyer-centric

Recommendation by use case

  • Best overall for most programmatic ops teams: Google Ad Manager + DV360/Authorized Buyers
  • Best for premium supply / publisher-led PMPs: Magnite
  • Best for buyer-side control and optimization: The Trade Desk
  • Best for enterprise matching and flexibility: Xandr
