At a glance

Gross media spend on The Trade Desk (TTD), the leading independent enterprise programmatic DSP. Sums spend across all campaigns. TTD is the enterprise gold standard for programmatic: deepest CTV inventory deals, most sophisticated audience tooling (Unified ID 2.0, Kokai/Koa AI bidder), strongest measurement infrastructure. If you’re running enterprise programmatic in 2026 and you’re not on TTD or DV360, you’re an outlier.

Worked example

A US enterprise homeware brand running TTD as the primary programmatic DSP alongside DV360 and Google Ads. The 30-day window is 02 Apr 26 to 01 May 26. What’s interesting:
  1. CTV is 48% of spend at 61,200∗∗splitacrosspremiumPMP(Disney+/Huluat61,200** split across premium PMP (Disney+/Hulu at 35.67 CPM) and open exchange (13.14CPM).ThePMPpremiumreflectsdirectdealswithmajorstreamers,thekindofinventoryaccessTTDhasthatStackAdapt/MediaMathcannotreliablymatchin2026.∗∗PremiumCTVat13.14 CPM). The PMP premium reflects direct deals with major streamers, the kind of inventory access TTD has that StackAdapt/MediaMath cannot reliably match in 2026. **Premium CTV at 35 CPM is fair enterprise pricing; open exchange at $13 CPM is mid-market quality.
  2. **DOOH at 8,400isdifferentiated.∗∗Digitalout−of−home(billboards,transit,retail−environmentscreens)isaTTDstrengthviadirectpartnershipswithLamar,ClearChannel,JCDecaux.∗∗NopeerDSPhascomparableDOOHinventoryaccess.∗∗8,400 is differentiated.** Digital out-of-home (billboards, transit, retail-environment screens) is a TTD strength via direct partnerships with Lamar, Clear Channel, JCDecaux. **No peer DSP has comparable DOOH inventory access.** 3.50 CPM is the right number for awareness-quality outdoor.
  3. Display at $3.81 CPM is healthy mid-market rate; Koa is finding brand-safe inventory at the efficient frontier.
  4. Cross-device retargeting via Unified ID 2.0 ($9,800) is the platform’s quiet differentiator. Same user followed across web, mobile app, CTV, audio without third-party cookies. The retargeting CPM is low because UID 2.0 enables tighter audience match; it’s not cheaper inventory, it’s better inventory.
  5. The 30-day prior was $108,000 spend; up 19% this window. Cause: Koa exited learning phase on the Display Prospecting campaign on 09 Apr 26 plus NBA playoffs CTV CPM lift. Both healthy.
  6. Compare to MediaMath (if running parallel during migration): TTD typically delivers 5, 15% better CPC on equivalent display inventory and 10, 25% better CTV view-through attribution clarity due to UID 2.0 cross-device match.
Quick sanity tests:
  • Spend up + impressions up + CPM stable = healthy scaling.
  • Spend up + CPM up = bidding into more expensive inventory; check Koa exploration mode.
  • Spend up sharply + CTV CPM spike = seasonal premium (sports, awards, holidays); decide whether to throttle or accept.
  • Spend down + impressions down sharply = inventory partner pulled back OR Koa bid below floor; rare on TTD given inventory access.
  • DOOH spend rising = check if seasonal campaigns (transit, retail) align with intent.

Sibling cards merchants should reference together

Reconciling against the vendor’s own dashboard

Where to look in The Trade Desk: TTD Platform → Reports → Performance → Spend column at advertiser level for the same date range. Should match this card to within sub-percent rounding once ingest catches up (allow 30, 60 minutes for “today”). Other TTD views that look similar:
  • Reports → Channel Breakdown: spend per channel (display, native, CTV, etc.). Sum matches account spend.
  • Reports → Inventory: spend per supply path. Same total.
  • Working Media: spend net of TTD fee. NOT what this card uses; this card uses gross.

Known limitations / merchant FAQs

My TTD spend just spiked, what happened? Standard DSP causes: (1) Koa exited learning phase; (2) PMP deal kicked in; (3) seasonal CTV CPM rise; (4) cross-device retargeting expansion via UID 2.0; (5) DOOH campaign launch. TTD-specific: Kokai (TTD’s next-gen platform launched 2024) sometimes ramps spend faster than legacy Koa during initial campaign-graduation; if you’ve recently migrated a campaign to Kokai, expect a 20, 40% volume bump in the first 14 days. TTD vs DV360, when do I pick which? Both are enterprise-grade. Pick TTD if: independent (non-Google-tied) ecosystem matters strategically, you need cross-device retargeting via UID 2.0, you want premium CTV inventory deals, or you run DOOH. Pick DV360 if: deeply integrated with the Google ecosystem (GA4, Google Ads, YouTube native), prefer Google’s audience tooling, or your agency standardises on Google stack. Most enterprise advertisers run both for inventory diversification. TTD vs MediaMath, why is everyone migrating? MediaMath’s Jun 23 Chapter 11 left the platform with reduced engineering investment, slower reporting, and inventory partner attrition. TTD has the opposite trajectory: heavy investment, fast reporting, and growing inventory access. The migration math is now simple for most advertisers; the few who remain on MediaMath have specific PMP deals or operational reasons, not platform-quality reasons. Why is CTV CPM so much higher on TTD than StackAdapt? TTD has direct PMP deals with Disney+/Hulu, NBC, Paramount+, etc., giving access to premium CTV inventory at 30,45CPM.StackAdaptroutesthroughSSPs(Magnite,Pubmatic)forCTVat30, 45 CPM. StackAdapt routes through SSPs (Magnite, Pubmatic) for CTV at 10, 20 CPM, which is lower-quality inventory at the same impression count. The CPM premium reflects real inventory quality difference, not platform overhead. My CTV campaign reports zero clicks, is something broken? No. Same as on every DSP, CTV impressions can’t generate clicks. UID 2.0 cross-device attribution lets TTD measure CTV-driven web/mobile conversions more reliably than peer DSPs, but the click events themselves still don’t exist. What does Kokai/Koa actually do? Koa is TTD’s machine-learning bidder (launched 2018); Kokai is the 2024 next-gen platform that includes Koa plus an upgraded measurement and attribution layer. In practice: real-time bid optimisation across user, context, recency, audience-match signals, comparable to BidCore (StackAdapt) and Brain (MediaMath) in principle, with TTD’s edge being data quality (UID 2.0 cross-device match) and inventory quality (more PMPs). Why does my GA4 show fewer TTD sessions than TTD reports clicks? Standard DSP-GA4 gap: ad-blocker leakage, bounces, ITP. TTD typically reconciles 88, 96% of clicks to GA4 sessions, tighter than StackAdapt or MediaMath because UID 2.0 reduces some of the cross-device attribution friction. Below 85% reconciliation suggests broken UTM tagging. Can I trust the “today” spend? More than on peer DSPs. TTD’s real-time reporting is fastest in market (15, 30 min lag); “today” is reasonably reliable. Still, use 7-day rolling for the actionable read. What’s the platform fee? TTD charges a percentage of working media; varies 15, 25% by volume tier. Enterprise direct customers (>$1M/month) negotiate down to 12, 18%. Fee included in this card’s gross spend. Should I use Unified ID 2.0? Yes if you can. UID 2.0 enables cross-device attribution without third-party cookies; for retargeting and CTV measurement specifically, it’s the strongest available substitute for the deprecated cookie ecosystem. Implementation is non-trivial (requires email-hash exchange via UID 2.0 framework) but the measurement uplift is material.
