New ad fraud report finds 2x higher fraud rates in automated campaigns, a sharp rise in MFA placements, and growing risk in short-form video advertising

TOKYO, JP / ACCESS Newswire / April 2, 2026 / Spider Labs today released its 2026 Ad Fraud White Paper Report, an annual analysis of global ad fraud trends estimating that advertisers lost more than $32.6 billion to ad fraud in 2025. The report finds that as ad spend rapidly shifts into AI-optimized campaign environments, fraud is becoming harder to detect and more likely to distort optimization and conversion signals.

The report is based on Spider Labs' 2025 data, including the analysis of more than 6.05 billion clicks, $6.2 billion in estimated ad spend, 174,483 analyzed domains, and campaign activity across 242 countries and regions.

A core finding is that the ad industry's move toward AI-driven delivery is creating a visibility problem for advertisers. As platforms automate more bidding, placement, and optimization decisions, it becomes harder to verify whether campaign learning is being shaped by real customer intent or by invalid traffic.

"AI is changing how performance advertising works, but the quality of the outcome still depends on the quality of the input," said Satoko Ohtsuki, CEO of Spider Labs. "If fraud enters the system as a learning signal, advertisers are not only losing budget, but they are teaching campaign algorithms to optimize toward the wrong outcomes as well."

Among the report's most notable findings:

• Massive Financial Impact: Estimated global ad fraud losses reached $32.6 billion in 2025.

• Higher Risk in AI Campaigns: Fraud rates in AI-optimized campaigns represent up to a 2x higher risk compared to average campaigns.

• The MFA Surge: Spider AF detected placements on made-for-advertising (MFA) sites increased by a staggering 14x from last year.

• Short-Form Video Vulnerability: In short-form video environments, Spider Labs observed a 12.79% fraud rate (about 2.7x above average), with the vast majority tied to organized click farms.

The full report also details how this invalid traffic actively damages conversion rates, and provides a breakdown of the specific industries facing the highest fraud exposure today.

Spider Labs notes the findings reflect a broader shift in how advertisers need to think about campaign protection. The company argues that advertisers need a quality control layer between media delivery and conversion data so that only validated signals are fed back into campaign systems.
