Editorial Team The Association of National Advertisers (ANA) just put a number on our collective headache, reporting that advertisers could lose over $23 billion globally to CTV ad fraud by the end of 2026. This isn’t some abstract future problem. It’s actively tanking the effectiveness of Connected TV advertising campaigns right now, trashing media integrity and forcing us all to rethink how we measure anything. How much of your budget is just feeding bots?
Key Takeaways
- Projected losses of over $23 billion globally to CTV ad fraud by 2026 means you need a plan, now.
- Bots have gotten so sophisticated they mimic human viewing behavior, which makes most traditional fraud detection useless.
- You have to use multi-vendor verification and demand transparent, auditable impression logs from all your ad tech partners.
- Shift your spend toward direct publisher relationships and private marketplaces (PMPs) to cut your exposure to fraudulent inventory.
- Get in the habit of auditing your ad delivery logs for strange patterns, like impossibly high completion rates on obscure videos or a flood of non-standard device IDs.

Context: The Evolving Threat Field
The promise of CTV, targeted reach, engaged audiences, was always going to attract scammers. A few years ago the fraud was clumsy and easy to catch, mostly coming from suspicious IP addresses or ridiculous view counts from one device. That’s changed. We’re now up against botnets that impersonate real human behavior so well they even fake mouse movements or remote control clicks, a development that should be terrifying to anyone looking at their delivery logs. A recent Pixalate study found that nearly 20% of all programmatic CTV ad impressions in Q4 2025 were invalid, which is a huge jump from the year before. Wasting the ad spend is bad enough, but this also corrupts the very data we use to optimize campaigns and allocate budgets.
CTV is especially vulnerable because the whole market is a fragmented mess. With so many different device makers, operating systems, and streaming apps, any attempt at creating a standard for ad verification has gone nowhere fast. Ad servers are often just taking a publisher’s or SSP’s word for it on performance, relying on self-reported data that creates a massive opening for bad actors to pump fake inventory into the system. And since the CPMs for premium CTV spots are so high, it’s an incredibly profitable target for them.

Implications for Advertisers and Media Integrity
The most immediate hit is to your wallet. When you pay for impressions that are never seen by an actual person, your return on ad spend (ROAS) calculations become garbage and you start making strategic decisions based on lies. The damage also destroys trust. When marketers see their campaign results get twisted by fraud, they lose faith in the entire digital advertising market, which can cause them to pull back investment in CTV and slow down growth for everyone.
Think about your attribution. If a big slice of your CTV placements are fraudulent, your models will mistakenly give credit to other channels or even organic search for sales that came from nowhere. That mistake then skews your next budget cycle, causing you to pull money from channels that are actually working. This lack of reliable measurement also makes it nearly impossible to hold your ad tech partners accountable. Without clean, verifiable data on valid impressions, advertisers are stuck trying to figure out which vendor is siphoning off their budget. It’s a systemic issue that needs a coordinated industry fix, not just individual brands playing whack-a-mole.
What’s Next: A Path Forward
To fight CTV ad fraud, you have to get aggressive. Start by demanding total transparency from your ad tech partners. You must insist on getting detailed impression logs with IP addresses, device IDs, and user agent strings so you can run your own independent verification. Working with a third-party verification company like DoubleVerify or Integral Ad Science (IAS) is no longer a nice-to-have for any serious CTV ad spend. It’s a requirement. These platforms are built specifically to detect the sophisticated invalid traffic (SIVT) that your basic in-house tools are guaranteed to miss.
You should also shift more of your CTV budget into direct deals with premium publishers or into curated private marketplaces (PMPs). Fraud can still happen there, of course, but that direct relationship gives you a much better line of sight and an actual person to hold accountable. You also need to actively monitor your own campaign performance for red flags. Are you seeing weirdly high completion rates on obscure content, sudden impression spikes from unrecognized devices, or a ton of engagement from a country you don’t even target? Groups like the IAB Tech Lab are pushing for more standardized measurement, but adoption is painfully slow. Until those standards are actually enforced across the board, constant vigilance and proactive verification are your only real defenses against this invisible drain on your ad budget.
This flood of CTV ad fraud demands a real response from advertisers and the ad tech industry. Ignoring this just means you’re throwing money away and losing your grasp of campaign effectiveness, which will eventually choke off growth in a really important channel. It’s time to take control. Demand transparency from your partners and implement tough verification protocols.
