At a glance

Gross media spend on MediaMath, the enterprise programmatic DSP (TerminalOne / T1 platform). Status note (May 26): MediaMath filed Chapter 11 in Jun 23; the platform was acquired and partly relaunched but its commercial footprint is reduced and many merchants have migrated to The Trade Desk or DV360. If you’re still spending here, verify the contract is current and fees/inventory are still as configured; flag discrepancies in Reconcile below.

Worked example

A US enterprise homeware brand running MediaMath as a legacy commitment alongside The Trade Desk and DV360. The 30-day window is 02 Apr 26 to 01 May 26. What’s interesting:
  1. **CTV is 39% of spend at 28,400∗∗throughaprivatemarketplacedealwithNBCat28,400** through a private marketplace deal with NBC at 31.55 CPM, premium inventory pricing. PMP deals were one of MediaMath’s enterprise differentiators; if the deal is still honoured post-restructure, that’s high-quality CTV at fair enterprise pricing.
  2. Display CPM at $3.65 is healthy for run-of-network programmatic display; Brain is finding brand-safe inventory at the mid-market CPM band.
  3. **Video pre-roll at 7.62CPMisthestandoutcost.∗∗Pre−rollonYouTube−qualityinventorytypicallyruns7.62 CPM is the standout cost.** Pre-roll on YouTube-quality inventory typically runs 9, 15 CPM enterprise-grade; $7.62 suggests run-of-network mid-quality, fine for awareness but not premium.
  4. The 30-day prior had $61,000 spend; this window is up 18%. Check whether the rise is (a) a real campaign expansion, (b) seasonal CTV CPM spike, or (c) an unexplained billing event from the post-restructure platform; the third option is non-zero on MediaMath specifically.
  5. Compare this $72k spend allocation to your TTD/DV360 spend. Many enterprise advertisers maintain MediaMath as a legacy hold-out (e.g. inventory deals locked in before restructure); the question is whether the deal value justifies the operational complexity of maintaining a third DSP. The migration trend is unambiguous; if you’re not getting demonstrably better inventory or pricing, consolidation usually wins.
Quick sanity tests:
  • Spend up + impressions up + CPM stable = healthy scaling.
  • Spend up + CPM up + impressions flat = paying more for same volume; check seasonal pressure or PMP deal terms.
  • Spend up but T1 UI shows different number = reconciliation issue, possibly billing artefact; investigate before accepting.
  • Spend dropping while campaigns active = potential platform issue; reach out to MediaMath account management before assuming campaign-level issue.
  • Pre-roll CPM rising sharply = inventory degrading or PMP deal lapsing.

Reconciling against the vendor’s own dashboard

Where to look in MediaMath T1: MediaMath TerminalOne (T1) → Reports → Campaigns → Spend column at organisation level. Should match this card to within sub-percent rounding. MediaMath-specific reconciliation caveat (post-restructure): Since the Jun 23 Chapter 11 and subsequent acquisition, the T1 reporting layer has had intermittent reconciliation issues. If this card and T1 UI differ by >5%, do not assume our card is wrong; check with MediaMath account management before adjusting downstream reporting. Contract renegotiations and fee restructures during 2024, 2025 also created edge cases where billed spend differs from impression-served spend. Why our number may legitimately differ from T1: Cross-connector reconciliation:

Known limitations / merchant FAQs

Should I still be running MediaMath? That’s a strategic question, not a metric one. The honest answer: most enterprise advertisers have migrated to The Trade Desk or DV360 since the Jun 23 Chapter 11. If you’re still on MediaMath, the typical reasons are: (a) locked-in PMP inventory deals that are still honoured and well-priced, (b) operational complexity of migration not yet justified by the savings, (c) specific Brain bidding edges in narrow use cases. Run the math: if MediaMath ROAS is within 10% of TTD/DV360 on like-for-like inventory, the migration cost may not pay back; if MediaMath is materially worse, consolidate. My MediaMath spend just spiked, what happened? Standard DSP causes first: (1) Brain exited learning phase; (2) PMP deal kicked in with new inventory; (3) seasonal CPM spike. Then a MediaMath-specific cause: (4) post-restructure billing artefact, occasionally the platform processes billing batches that hit the spend ledger with delay, creating apparent spikes that don’t correspond to actual impression delivery. Reconcile to T1 UI before assuming it’s real. Why is MediaMath ingest slower than my other DSPs? The post-restructure platform has reduced engineering investment in real-time reporting infrastructure compared to TTD/DV360. Expect 2, 4 hour lag where peers are 30, 60 minutes. If you need real-time pacing, set tighter daily caps in T1 directly rather than waiting for downstream signals. My MediaMath PMP deal is delivering less than expected, what should I check? Three things, in order: (1) Contract status, has your CTV PMP deal been renegotiated post-restructure, possibly with revised CPM or impression caps? (2) Inventory share, post-restructure, MediaMath’s relative share of CTV inventory access has compressed; the deal may still be honoured but with smaller available volume. (3) Frequency cap interaction, if your campaign frequency cap is tight, the PMP can’t deliver above it. Can I trust the “today” spend figure? Less than rolling 7-day. Today’s spend reads from incomplete intra-day ingest, which on MediaMath is slower than peers. Use 7-day rolling for actionable reads. What’s MediaMath Brain (vs StackAdapt BidCore vs TTD Koa)? Brain is MediaMath’s machine-learning bidder, branded distinct from peer DSP bidders. In practice all three (Brain, BidCore, Koa) operate on similar principles: real-time impression evaluation across user, context, recency, audience-match signals; ML-driven bid optimisation. Performance differences are within 10, 15% on equivalent inventory, individual campaign variance dominates the headline difference. Should I migrate now or wait? Most enterprise advertisers who haven’t already migrated have made an explicit decision to stay (locked-in deals, operational reasons). If you’re undecided in 2026, the migration window has passed, do the math on TCO (total cost of ownership: licence + engineering + operational complexity) vs incremental performance and decide on actual numbers, not the chapter-11 narrative. My ROAS is fine but I’m worried about platform stability, what should I do? Maintain a TTD or DV360 account in parallel even if you’re not actively spending. The cost is minimal; the optionality is valuable if MediaMath has a further structural change. Many ex-MediaMath advertisers run shadow accounts at TTD specifically for this reason. Why does this card have a spend-spike alert specifically calling out billing artefacts? Because post-restructure MediaMath has had occasional billing-batch processing issues that produce apparent spend spikes without corresponding impression deliveries. The alert’s job is to surface anomalies; the diagnosis (campaign vs platform) is on you.
