The Supply Path Puzzle: Cutting Waste Without Cutting Reach
In digital advertising, the supply chain was meant to simplify buying, yet it has evolved into a tangled web of intermediaries, duplicated auctions, and hidden fees.
The Scale of the Problem
Recent studies from the ANA’s Q2 2025 transparency benchmark revealed that nearly $26.8 billion in programmatic waste exists within the current ecosystem. The issue is not just inefficiency; it’s the realisation that a significant portion of spend never reaches meaningful media, forcing advertisers to rethink how they evaluate the best supply paths.
According to Marketing Dive, citing the ANA’s 2024 findings, only 43.9 percent of programmatic spend reaches actual consumers. This means more than half of every dollar still gets lost due to non-viewable impressions, invalid traffic, or low-quality inventory. Meanwhile, MonetizeMore estimates that 40 to 60 percent of ad dollars disappear due to opaque supply chains, excessive SSP fees, and duplicate bid requests.
The Transparency Gap
IAB Europe highlights that publishers receive only 51 percent of programmatic spend, with approximately 15 percent categorised as an “unknown delta” in the ISBA/PwC supply-chain study. This gap represents untraceable costs that advertisers simply cannot account for. These numbers show that the problem is not just a theory; it runs deep within the system.
What Advertisers Actually Need
The market is shifting. Advertisers no longer want maximum reach at any cost, they want efficient reach through verified, quality inventory.
With cookie deprecation accelerating and scrutiny on ad quality intensifying, the old playbook of casting the widest possible net is becoming obsolete. Today’s winning strategy centres on:
- Curated marketplaces with pre-vetted inventory
- High-trust supply paths that eliminate waste
- Transparent routing that shows exactly where budget goes
- Quality over quantity in supply partner selection
The Solution: Smarter Supply Path Optimization
Technology is rewriting the rules of supply path optimization. Modern solutions now leverage intelligent routing, quality scoring, and predictive optimization to help advertisers find shorter, cleaner paths to premium inventory. The question is no longer “How many supply partners do we have?” but rather “What value does each partner actually deliver?”
