## Summary
Programmatic guaranteed (PG) is the deal type that pairs the workflow automation of programmatic with the inventory commitment and fixed CPM of an upfront — the dominant transaction shape for premium CTV inventory where supply is finite and sellers refuse to expose it to open auction.
## Definition
A programmatic guaranteed deal is a one-to-one agreement between a single buyer and a single seller for a fixed number of impressions at a fixed CPM, transacted through programmatic plumbing rather than insertion orders. In the IAB OpenRTB specification, PG is signaled inside the PMP/Deal object with auction type `at = 3` ('fixed price'), where the deal's `bidfloor` field carries the negotiated CPM rather than a minimum bid. Unlike a private marketplace (PMP), where multiple buyers compete in a closed auction, or an open auction, where any DSP can bid, PG removes the auction entirely — the impression is reserved for one buyer, who is contractually obligated to take the volume. Buyers use PG when they need delivery certainty against premium inventory (CTV originals, live sports, homepage takeovers); sellers use it when they need revenue forecastability from inventory they would otherwise have to reserve manually through a direct sales team.
## Market size
Programmatic guaranteed accounts for an estimated 38% of US CTV programmatic ad spend in 2026, with PMP at 47% and open auction at 15% — and CTV programmatic is projected to reach approximately $36 billion globally.

## Key trends

- PG is taking share of CTV programmatic spend as upfront-style buyers shift workflows onto programmatic plumbing without giving up inventory commitments — Netflix, Disney, and NBCUniversal premium inventory now routes primarily through PG and curated PMPs, not open auction.
- IAB Tech Lab's Programmatic Governance Council, launched April 2026, has put auction transparency, bid duplication, and transaction-ID handling at the top of its 90-to-120-day workplan — with implications for how PG deals are signaled and reconciled across the supply chain.
- Curated CTV PMPs (Magnite ClearLine, PubMatic Activate) are blurring the line between PG and PMP — buyers get PG-style premium inventory access with PMP-style audience flexibility, eroding the historical PG/PMP boundary.
- DSP fee structures increasingly favor PG: Amazon DSP and DV360 charge meaningfully lower take rates on PG inventory (~4% on DV360 PG vs. 10–15% on open auction), pulling more spend toward guaranteed deals on cost grounds alone.
- Live sports and CTV originals — where supply is finite and demand spikes are predictable — have become the PG-only categories; sellers refuse to expose this inventory to PMP or open auction.

## Key facts

- In OpenRTB 2.6, the Deal object's `at` (auction type) field uses value 3 to signal a fixed-price deal — the standard signaling pattern for programmatic guaranteed transactions, where the `bidfloor` carries the negotiated CPM. — IAB Tech Lab — OpenRTB 2.6 Specification: https://github.com/InteractiveAdvertisingBureau/openrtb2.x/blob/main/2.6.md

## Profile
Programmatic guaranteed exists because the two halves of the digital advertising stack — the certainty of a direct-sold upfront and the automation of programmatic — were, for most of the last decade, mutually exclusive. A buyer who wanted guaranteed delivery against Disney's NFL inventory or a Netflix premiere had to do it through an insertion order, faxed energy and all. A buyer who wanted programmatic workflow had to accept whatever the auction surfaced. PG collapsed the distinction: a fixed CPM, a fixed impression count, a contractually committed buyer and seller — but executed through the same DSP-to-SSP plumbing that routes open-auction bids.

The mechanics are straightforward and codified. In OpenRTB 2.6, a PG deal is just a Deal object with auction type `at = 3` — fixed price — where the `bidfloor` field carries the negotiated CPM rather than a floor. The SSP routes 100% of matching impressions to the designated DSP; the DSP is contractually obligated to bid; the seller is contractually obligated to deliver the volume. Google's DV360 layers a `must_bid` signal on top, so the buyer can pace inside the deal. Everything else — creative approval, frequency capping, audience overlay — runs through the same pipes as a PMP or an open-auction buy.

What changed in 2026 is where PG sits in the spend mix. eMarketer's CTV breakdown puts PG at roughly 38% of US CTV programmatic spend, with PMPs at 47% and open auction at a residual 15% — a near-inversion of the desktop display ratio. The reason is supply: Netflix, Disney, NBCUniversal, and the major broadcasters refuse to expose premium CTV inventory to open auction, and the curated PMP layer (Magnite ClearLine, PubMatic Activate) is increasingly indistinguishable from PG in everything but the contract language. DSP fee structures reinforce the trend — DV360 charges roughly 4% on PG versus 10–15% on open auction, and Amazon DSP applies a similar discount on PG against its owned inventory.

The open question for the next 12 months is governance. The IAB Tech Lab's Programmatic Governance Council, launched in April, has put auction transparency, transaction-ID handling, and bid duplication at the top of its workplan — all of which sit upstream of how PG deals are signaled, reconciled, and audited across the supply chain. PG's growth has outrun the standards body's ability to specify what a "fixed-price deal" actually means at the bid-stream layer, and that gap is where the next round of trade-press argument will land.
