By 2026, programmatic purchasing will amount to 74% of all ad revenue on the open internet. Consequently, if media companies ignore supply path calculations, they will lose substantial portions of their net yield.
This article presents factual evidence as to the actual prices, metrics, and experiences associated with various ad tech companies that control the current market, without the marketing hype or spin provided by vendors.
The Economics of Programmatic Infrastructure
The advertising technology industry is substantial and heavily consolidated.
Estimates suggest that the total global advertising technology market will exceed between $986 billion and $1.11 trillion by 2026. A significant factor contributing to this growth is the movement toward bidding automation. Thus, the projected compound annual growth rate (CAGR) for this industry is projected to exceed 14% for the long term, pushing total market size to more than $2.55 trillion by the early 2030s.
Market shares are dominated by only a handful of companies. The three major walled gardens—Google, Meta and Amazon—control about 54.7% of the global digital advertising marketplace (outside of China). Independent open internet platforms have to compete for the remaining 45% of ad spend. Advertisers need to make a choice: contract their budgets with closed ecosystems and have a large audience but not much visibility as to how their money is being spent, or build a stack for the open web that requires significant technical expertise but gives them complete control of fees.
Retail media networks (RMNs) have completely changed how budgets are utilized. U.S. commerce media networks will exceed $100 billion in ad spend by 2026, and they are projected to grow at a CAGR of 21%. Retailers have entered into this space by selling their customer data at significant margins. Currently, Amazon controls 77% of retail media ad spending.
Connected television (CTV) will be the second major area for growth. The consolidation of premium video budgets is being driven by the actions of device manufacturers such as Roku, Samsung, and LG, as well as content companies such as Disney and Netflix.
Artificial intelligence will control the bidding results for all advertisers. By 2026, the AI advertising market is expected to reach $14.12 billion, with estimates reaching $36.34 billion by 2030.
AI automation is now the minimum requirement for anyone wishing to compete in a real-time bidding environment; there are no longer any premium features associated with AI, as they have all become the basic minimum for any competition.
Independent Demand-Side Platforms and Top Ad Tech Companies
Demand-side platforms (DSPs) focus on advertisers and agencies as a centralized way for them to purchase inventory through exchanges in milliseconds.
1. The Trade Desk
The Trade Desk is the largest independent DSP within the industry. It has built its business on an anti-walled garden philosophy, calling for total transparency across the connected TV, digital audio, and display marketplace. They manage roughly 3 to 5 percent of all global programmatic spend.
The Trade Desk operates primarily with large businesses and large holding companies.
The Trade Desk has a custom pricing structure designed for enterprise buyers, with monthly minimum spending requirements. There are no short-cut options to contracting with The Trade Desk for smaller agencies to get started. In 2025, they launched an AI platform called Kokai to be used for processing and evaluating real-time auction algorithms to filter through ad fraud at massive amounts.
The Trade Desk's market cap is approximately $9.8 billion, making it the leading option for all agencies wishing to move budgets away from Google.
2. StackAdapt
StackAdapt offers a self-service DSP for mid-level brands and agencies. The StackAdapt platform offers native, display, video, connected TV, and digital audio capabilities for all advertisers.
Unlike traditional enterprise platforms which do not highlight their minimum spend thresholds, StackAdapt clearly indicates its lowest tier program (starting at around $1,000/month).
For scaling agencies unable to support the large dollar amounts needed for The Trade Desk's platform, the low entry point offered by StackAdapt makes it a very attractive option. Agencies utilize StackAdapt heavily for speed to market through rapid testing of creative content and highly repeatable audience modeling processes.
StackAdapt's user-friendly features allow agencies to quickly activate multiple client accounts without the burden of extensive operational costs.
3. Criteo
Criteo built its name on the strength of its aggressively retargeting algorithms. Today, Criteo has evolved into a large commerce media platform. In addition to retargeting, Criteo has developed a compelling offering to retailers in the area of artificial intelligence-based personalized solutions.
Criteo uses a unique pricing model based upon the individual advertiser's performance.
Criteo sits neatly between the traditional programmatic purchasing methodology and the exploding interest in retail media networks. Retailers need ways to make money from their on-site traffic, and Criteo connects directly with retailer media networks as part of their base campaigns.
Criteo helps retail and e-commerce brands create highly tailored product advertisements that will be displayed to consumers who have demonstrated a real interest in purchasing that particular product.
4. Amazon Advertising
The Amazon Advertising solution includes an on-platform sponsored ads product as well as an off-platform DSP product.
Amazon has the competitive advantage of having access to a large database of closed-loop e-commerce data. Amazon currently controls 77% of the entire retail media market.
Amazon currently generates over $50 billion in ad revenue every year.
Amazon's off-platform DSP employs a customized pricing model, while Amazon's internal marketplace is built on a standardized cost-per-click (CPC) or cost-per-thousand (CPM) auction system. The strength of Amazon's data is clearly demonstrated by numerous case studies.
A recent documented success story highlights how Ariat utilized the Amazon DSP to achieve an amazing 620% increase in click-through rates, while also achieving a 72% reduction in effective cost-per-clicks (CPC). ROAS increased by 60%, showing how linking the delivery of ads to actual purchase data can eliminate waste from the system.
5. Adobe Advertising Cloud
The Adobe Advertising Cloud is an enterprise-level DSP that is purpose-built to integrate directly with Adobe Analytics, Audience Manager, and Creative Cloud.
The initial investment required for the Adobe platform is significant.
According to industry reports, pricing typically begins at $50,000 a year (not including the cost of the actual media purchased) and is aimed at larger global companies that are already utilizing the Adobe Experience Cloud for their marketing data. Adobe Sensei AI is used to provide the central hub for coordinating all cross-channel deliveries (ad served, media bought, and comprehensive reporting).
6. MediaMath
MediaMath is an independent DSP and one of the premier ad tech companies heavily focused on supply chain transparency and data-centric targeting. The MediaMath platform offers buyers and agencies a great deal of flexibility with their buying workflows.
MediaMath's pricing is customized depending on the unique needs of the buyer.
Typically, this is preferred by agencies and buyers that take an analytical approach to bidding and want to retain a high level of control over their bidding algorithms. MediaMath emphasizes the importance of providing data-driven advertisers with privacy-centric features allowing them to remain compliant with stringent data handling regulations, while maintaining the ability to accurately target their audience.
7. Quantcast
Quantcast provides a data-driven approach to audience insight. This programmatic DSP is focused on the SMB and mid-market sectors through the use of AI technologies. Prices start out at a very low level of around $500 a month, making Quantcast one of the most accessible AI-based buying platforms available in the market today.
Quantcast provides an opportunity for smaller brands to take advantage of their AI audience prediction technology to outgrow their target market. With Quantcast, advertisers with limited resources can now access AI modeled targeting technologies that have previously only been available via large enterprise contracts.
8. Adform
Adform represents one of the largest independent DSPs, ad servers, and data tools in the world with an impressive presence in the European market.
The price is negotiated based on the type of data you need and the quantity of the data.
Adform is set up with an emphasis on transparent fees and strict privacy policies due to European Union laws surrounding data. Adform is used primarily by mid-tier and larger companies to control and manage their cross-channel advertising strategies and to make it easy to manage private deals.
9. RTB House
RTB House uses deep-learning algorithms for retargeting and prospecting campaigns that are executed on the open web and has an impressive footprint in the EMEA (Europe, Middle East, Africa) region.
Pricing is custom-based and performance-based.
RTB House utilizes advanced deep-learning networks to build models of users' intentions to create predictable growth outside of the Google and Meta realms. Performance marketers use RTB House to achieve predictable growth through advanced algorithms based on sophisticated patterns.
10. Xandr
Xandr, the media company owned by Microsoft, is a strong contender in the video and connected TV advertising space and provides a bridge into other Microsoft products.
Pricing structures are custom-built for large enterprises. To create an effective video ad campaign, buyers can use Xandr to find high-quality video inventory and use search adjacency data that Microsoft collects through its digital advertising division. Xandr works especially well when the campaign is large and needs to access as much CTV inventory as possible, and Microsoft is the owner of the inventory being sold.
Supply-Side Platforms and Yield Engines
There are two types of online supply-side platforms (SSPs), which allow for automated auctions of publisher, app developer, and media owner ad spaces. Smart deployment of SSPs allows for greater yields for publishers and provides the ability to filter out bad ads.
1. Magnite
Magnite is the largest independent supply-side platform in the world today, focusing mostly on monetizing digital video (as opposed to traditional linear television). The company has made a push in both the digital video and CTV spaces.
Magnite charges custom fees depending on how much money is made through the sale of the designated inventory. The company has aggressively marketed itself as a platform with transparent fees.
Magnite was formed as a result of a merger between the Rubicon Project and Telaria, and today, the company is at the center of the CTV supply path. Agencies purchasing curated premium television inventory rely on Magnite to facilitate their transactions in a clean manner. As such, Magnite has quickly established itself as the primary competitor to Google Ad Manager for high-end publishers.
2. PubMatic
PubMatic is a fully cloud-based supply-side platform that maximizes supply path efficiency for publishers by utilizing advanced AI tools to improve yields across multiple channels of video and CTV inventory.
Pricing is based on a custom fee schedule, but PubMatic places special emphasis on transparency around its fees.
PubMatic's scale is mind-boggling, as the company processed 78 trillion ad impressions during Q2 of 2025 alone and simultaneously reduced its own costs by 20% from Q2 of the previous year. Due to high throughput rates and operational efficiencies realized by publishers using ad network technology platforms, they can generate more revenue while continuing to have access to large amounts of global advertising demand.
3. Index Exchange
Index Exchange is a global ad exchange that connects publishers with advertising buyers and is built around the best ad quality.
Publisher fees are customized and very much focused on 100% transaction transparency. The platform's primary value proposition is to provide low-latency auctions for agencies and brands wanting to source premium inventory that does not include hidden fees or take-rates that erode working media budgets. Transparency in publisher fees is one of Index Exchange's core product offerings.
4. OpenX
OpenX is a leading supply-side platform that differentiates itself by its commitment to quality, transparency, and environmentally sustainable advertising delivery.
The publisher pricing structure is customized and negotiated at an enterprise level.
OpenX allows publishers to operate private marketplaces (PMPs) efficiently, delivering a predictable stream of income. The platform conducts extensive checks for fraud and maintains high levels of ad viewability. Many startups and mid-market publishers prefer OpenX because the platform helps them maintain a strong pace for ad monetization while reducing the likelihood of experiencing unwelcome surprises in their monthly yield reports.
Mobile Advertising Networks and Discovery Networks
Ad technology does not only involve standard display and video advertising. There are also specialized networks for user acquisition mobile apps and native discovery content networks.
1. AppLovin
AppLovin is an industry leader in AI-based mobile advertising technologies and the core provider for user acquisitions in mobile gaming and mobile e-commerce.
The price structure for AppLovin is custom and typically based on strict CPC or CPA pricing models. A source estimates that the company has a market share of about 5 to 10 percent of the overall ad tech industry and has a corporate valuation over $100 billion. It utilizes two enormous engines to help facilitate its advertisements: AppDiscovery for customer acquisition and MAX for monetization through publishers. Developers rely on AppLovin to help generate high-value customers that will spend within the developer's app.
2. Taboola
Taboola has a monopoly of the native content discovery market. Taboola provides many types of content advertising campaigns.
Each content advertising campaign has its own unique pricing; however, many people using Taboola have said that they are receiving a very competitive CPM from the use of such advertising campaigns.
Taboola allows publishers to create new revenue opportunities for web pages that are already saturated with traditional display ads. When combined with ad management platforms, publishers see, on average, a lift of 32% in total ad revenue. Up to 23.5% of a publisher’s header bidding revenue could be attributed to Taboola, completely shifting the economics of traditional media websites.
Walled Garden Technology Monopolies
While many independent technological companies are working hard to keep the internet open, the major corporations are using their vast scale, along with closed-loop data, to monopolize most of the world’s advertising.
1. Google
Google is the leading example of this. Google (under the parent company Alphabet) controls every part of the advertising industry. Google owns both buy-side and sell-side advertising services, and Google has also developed an analytics tool.
All of Google’s pricing is done by way of the auction pricing model. However, large-scale enterprises using Google’s Marketing Platform have to negotiate custom contracts with Google to obtain pricing structures.
About 30 to 35 percent of the total ad tech market was reportedly controlled by Google in 2024. Google’s advertising tools, Display & Video 360, and Google Ad Manager are among the leaders in the industry. Inventory volume is unmatched. Google processes billions of searches and YouTube streams over a billion hours of video every day. Furthermore, buyers use Google because Performance Max and the machine learning tools of AI are constantly hitting the target cost of acquiring customers, even though the data is reported through Google's own internal reporting system.
2. Meta Platforms
Meta is the dominant player in the social advertising market on Instagram and Facebook, where they have the largest engaged audiences and use shoppable video formats (e.g., Reels, Stories).
As with Google, Meta uses a method of pricing through auction, where there are no minimums published.
Approximately 20-25% of the overall ad technology market is controlled by Meta. After a series of initial setbacks caused by Apple's App Tracking Transparency (ATT) rules, Meta began rebuilding their advertising engine using signals from the platform along with AI-based algorithms to predict how users will behave once they have been exposed to ads from their competitors. The results of these efforts cannot be overlooked: ad revenue has increased by 19% year over year and corporate profits have increased by 35%. If direct-to-consumer (DTC) brands and app developers want to reach their full potential, they must run Meta ads.
Infrastructure, Verification, and Leading Ad Tech Companies
Buying ads is pointless if they are running on fraudulent websites or the data cannot be tracked. Verification tools and layers of identity ensure that the digital marketing ecosystem remains operational.
1. Innovid
Innovid is a central source for all omnichannel video and CTV (connected TV) ad serving, creative management, and measurement.
The pricing model is entirely unique.
Brands and publishers that are running complex CTV campaigns use Innovid to bring all of their creative products together. Rather than relying upon the publishers to provide performance metrics, buyers use Innovid to get independent measurement across multiple publishers, confirming that the video ads are actually being rendered accurately on television screens.
2. LiveRamp
LiveRamp offers the main identity backbone for the cookieless internet through its RampID, Authenticated Traffic Solutions (ATS), and Habu clean rooms.
Enterprise pricing is structured for enterprises that require serious amounts of data to be unified.
Brands need to leverage their first-party data to survive in a post-cookie world. LiveRamp makes it easy to eliminate data chaos. A brand can upload a CSV file of their customers, find those customers with an anonymous identity graph, and target them with advertising on the open internet without violating privacy regulations.
3. Integral Ad Science
Integral Ad Science (IAS) provides in-depth verification, brand safety, and viewability tracking.
Contracts for pricing are typically tailored specifically for the enterprise space.
Big advertisers will not purchase open inventory without IAS wrapping their tags with verification. IAS filters out invalid traffic (IVT) and provides brand safety signals to ensure a corporate advertiser does not place a banner ad next to hate speech or illegal content.
4. DoubleVerify
DoubleVerify competes directly with IAS by providing similar services for brand safety, fraud prevention, and performance insights.
Contracts are done on a custom basis and heavily negotiated by large holding companies.
Large brands require contractual assurances of quality before spending millions on programmatic advertising. DoubleVerify takes the uncertainty out of this process. It tracks where ads load, prevents fraud before they bid, and helps advertisers optimize their creative placement based on how much real human attention is being paid to their ads.
5. AdKernel
AdKernel provides a white label programmatic infrastructure. The platform includes a fully developed proprietary DSP and ad tech stack.
The complete AdKernel solution (i.e., the DSP, ad serving platform, ad exchange, and header-bidding wrapper) is prebuilt and available for use. Custom pricing is set up to meet the unique licensing and technical needs of each user.
Ad networks and large ad agencies do not have to build their own proprietary technology stack from scratch over a two-year time frame at a multimillion-dollar cost. By licensing products from AdKernel, agencies can have their own private, branded bidding platform within weeks and will significantly reduce their risk of failure on the roadmap.
Supply Path Optimization and Workflow
Agencies are continually purchasing online inventory without confirming the entire supply path. Ultimately, these hidden costs lead to lower profitability. Buyers are now learning that they need to incorporate specific workflows based upon the channel mix and their budget.
Supply Path Optimization (SPO) is the process of eliminating the fees charged for intermediaries in the programmatic advertising space. When an agency purchases an ad through a DSP, dollars flow from the buyer through an exchange to a supply-side platform (SSP) to a data provider before reaching the publisher. Each of these layers charges a fee, known as the take rate. Therefore, a $5.00 CPM bid by an advertiser might actually generate a net CPM of $2.50 for the publisher.
With the introduction of Private Marketplaces (PMPs) and curated deals provided by modern ad tech companies, buyers will have the option to bypass these middlemen altogether.
A direct PMP with the publisher means a reduced take-rate, and the buyer pays a slightly lower gross CPM than the published rate, while the publisher receives a higher net CPM than they would receive from the standard purchasing model. In summary, both buyers and publishers are better off by eliminating unnecessary technology vendors that are getting between them.
Digital Campaign Structure
With new technologies available today, all digital performance marketing requires specific and unique creative structures. You cannot simply take your entire digital marketing budget and throw it at an unspecified DSP and expect to see a return.
To configure an effective digital advertising strategy, a marketing agency must break the workflow into three steps. First, they use CTV prospecting ad placements through channels such as StackAdapt or The Trade Desk to create broad audience awareness. Second, agencies then use a retail media network (e.g., Amazon DSP) to retarget people who have seen their CTV ads when they are actively searching for related products. Lastly, agencies must apply strict frequency control so that the target audience does not continue to be bombarded with display ad banners repeatedly.
To make this type of advertising successful, buyers must utilize cookieless identity frameworks. Products such as UID2, ID5, and Privacy Sandbox APIs enable ad platforms to follow users' paths across digital channels while using modern methods to replace the currently obsolete tracking pixel method.
In addition, advertisers must demand unquestionable transparency regarding the minimums for pricing structure. Some vendors advertise custom pricing when in fact they may be charging $50,000 per month as the absolute minimum, thereby eliminating small brands from utilizing advanced advertising setups.
Evaluate Your Ad Tech Platform Setup
All agencies involved in the purchasing of media programmatically should demand that their programmatic technology vendors publish the following to them: complete transparency of the supply-path take-rate of each ad placement made by their clients and the data fees assessed for each ad placement.
If the current DSP or SSP cannot produce this kind of detailed information, the agency should terminate the budget for this vendor and migrate to a vendor that will provide this information.
