AppNexus Replaced by a Chatbot, and MFA’s Finally on the Way Out?

AppNexus Replaced by a Chatbot, and MFA’s Finally on the Way Out?

The Google Antitrust Case Probably Shut Down AppNexus

They say time ravages all; well, time and AI have now caught up with one of the first big programmatic institutions. AppNexus wasn’t the first to engage in real-time bidding, but it was perhaps the first major platform that basically created and popularized the concept of a DSP. In 2018, AT&T bought AppNexus and renamed it to Xandr, before selling it once again to Microsoft in 2021. The company served ads as Microsoft Invest for a few years, but the tech giant has announced that the DSP will be shutting down for good next year.

It’s a sobering full-circle moment for the industry, but the already bummer of a situation is overshadowed further by Microsoft’s plans for a replacement: a Chatbot. As reported by AdExchanger, the DSP service will be fully automated through a chatbot-style product powered by Microsoft’s Copilot AI. The supply-side of the business – Microsoft Monetize – will remain intact.

Automation can do some incredible things, but it’s a shame to see such a large industry name over-streamlining the ad buying process. Self-serve programmatic solutions are annoying enough when advertisers have a hard time getting support from the platform, and now the possibility of talking to a real person has decreased even further; no-one enjoys talking to a chatbot.

The implications go deeper. The recent antitrust lawsuit against Google was founded on its participation in the open internet, a lawsuit that the Department of Justice just won and could mean substantial changes to the way Google runs its business. Microsoft’s decision to shutter the DSP services are surely linked to the outcome of the case; the major ad providers are moving away from 3rd-party vendors and increasingly stacking up the bricks on their walled gardens.

What does this mean for advertisers? On the one hand, it means that buying from the big players almost guarantees the use of first-party data, which tends to be more reliable in tracking and targeting the ideal audience. The increased emphasis on first-party data is welcome, but it comes at the cost of more closed-off networks that are harder to make work together. This is why it is paramount to not rely just on the big players, but find a partner that has access to the big players as well as the small networks and can consolidate the buy process with ease into one.

Programmatic works best when advertisers can reach their customers through a variety of networks and data sets, and even better when the platform and users are supported by a team of human programmatic experts. This remains the core philosophy of Genius Monkey: fully-managed campaigns delivering ads at precisely the right moment, regardless of the device.

MFA is Struggling, at least according to ANA

A 2023 report from the ANA was a wake-up call for many digital advertisers and publishers: the association suggested that nearly 35% of ad spend was being wasted on bogus placements that did little or nothing to help convert consumers. How could this be happening?

Part of the problem is the industry’s reliance on MFA. Many advertising platforms sell themselves on high page views and clicks, which MFA sites can indeed provide. At the time of the ANA report, many industry analysts suspected that a stark removal of MFA sites from the marketplace would be very disruptive to many legitimate advertising campaigns, since some platforms would suddenly lose a great deal of revenue.

Such a loss in revenue wasn’t an issue for Genius Monkey; our platform uses a triple-verification system to sort through the fraud and useless clicks, granting users confidence that >99% of their ad spend was being used for quality placements that engage the customer. Not every platform uses this kind of verification, however, so a complete removal of MFA wasn’t really in the cards for the industry as whole.

Nevertheless, lots of platforms took small steps to avoid MFA, and those combined efforts have started making a dent in the MFA space. In August 2024, Jounce Media (arguably the leading data platform combating MFA) reported that MFA bid request volume had fallen from a peak of 30% to just 10%.

Even more recently, Equativ – an SSP – reported only good news after two years of completely blocking MFA deals. What was seen as a risky step in 2023 has paid off with a bolstered perception of the company as a high-quality marketplace. More exchanges and platforms are adopting a similar “anti-MFA” policy, and the day may come when MFA is a tiny subset of the market that’s hardly worth worrying about.

The claims at large reductions of MFA are all well and good, but MFA is still at large. Genius Monkey has noted reductions as well, but our triple layer protection filters still catch it often. An industry-wide reduction is to be celebrated, but a thorough validation is still absolutely necessary to weed out the bad placements and truly optimize on performance.

Frequently Asked Questions (FAQ)

What happened to AppNexus?

AppNexus, one of the original pioneers of programmatic advertising and the DSP model, was acquired by AT&T in 2018 and rebranded as Xandr. Microsoft later purchased it in 2021, operating it as Microsoft Invest before announcing it would be shut down entirely.

What is replacing Microsoft's DSP?

Microsoft plans to replace its DSP service with a chatbot-style product powered by its Copilot AI. The supply-side of the business, Microsoft Monetize, will continue to operate as normal.

Why is Microsoft shutting down its DSP?

The decision is widely believed to be connected to the outcome of the Department of Justice’s antitrust lawsuit against Google. Major ad providers are pulling back from third-party vendors and doubling down on their own closed networks, often called walled gardens.

What does the rise of walled gardens mean for advertisers?

It means that buying from the big players will increasingly rely on first-party data, which is generally more reliable for targeting. However, these closed-off networks are harder to use together, making it more important than ever to work with a partner that can consolidate buys across both large and small networks.

What is MFA and why does it matter?

MFA, or Made for Advertising, refers to low-quality sites designed primarily to generate ad clicks and page views rather than deliver real value to consumers. A 2023 ANA report estimated that nearly 35% of ad spend was being wasted on these kinds of placements.

Has the industry made progress in reducing MFA?

Yes, meaningful progress has been made. Jounce Media reported in August 2024 that MFA bid request volume dropped from a peak of 30% down to just 10%, thanks in part to combined efforts across platforms and exchanges to block or avoid MFA inventory.

Are there real-world examples of anti-MFA policies working?

Equativ, a supply-side platform, completely blocked MFA deals two years ago and has since seen its reputation grow as a high-quality marketplace. What was considered a risky move at the time has turned into a competitive advantage.

How does Genius Monkey handle MFA?

Genius Monkey uses a triple-verification system to filter out fraudulent and low-quality placements, giving advertisers confidence that more than 99% of their spend goes toward quality inventory. Even as industry-wide MFA numbers decline, this kind of thorough validation remains essential.

Should advertisers still be worried about MFA today?

While the overall volume of MFA has dropped significantly, it has not gone away entirely. Strong filtering and verification tools are still necessary to protect ad spend and ensure campaigns are truly optimized for performance.

What is the takeaway for advertisers navigating these industry changes?

The fundamentals of digital advertising have not changed: getting your message in front of the right audience at the right time still matters most. Working with a fully managed platform like Genius Monkey, backed by human expertise and robust fraud protection, remains one of the best ways to navigate a shifting landscape.
