The State of Fraud for Marketers — 2026 Edition

Why It Matters

Marketers face higher absolute losses despite stable fraud percentages, forcing tighter verification and budget reallocation across channels.

Key Takeaways

• Organic traffic generates 52% of all fraudulent installs
• Affiliate‑SRN fraud gap widened to 36‑times difference
• Fraud volume rose with increased ad spend despite flat rates
• Android and iOS fraud techniques shifted, altering detection priorities

Pulse Analysis

The mobile advertising ecosystem continues to expand, with global marketers allocating record budgets to user acquisition. While the headline fraud rate held steady in 2025, the sheer scale of spend pushed the absolute count of fraudulent installs to new highs, as AppsFlyer’s analysis of more than 100 billion installs shows. This paradox—stable percentages but rising losses—highlights that traditional fraud‑rate metrics can mask the true financial impact on campaigns, especially for brands scaling rapidly.

A striking insight from the report is that organic channels now account for 52 % of fraudulent installs, overturning the long‑held belief that paid media is the primary culprit. Meanwhile, the disparity between affiliate‑driven fraud and self‑served network (SRN) fraud exploded to a 36‑fold gap, indicating that affiliates are either more vulnerable to bad actors or that detection tools lag behind their tactics. On the technical front, the mix of fraud techniques on Android and iOS shifted, with device‑farm attacks declining and SDK‑level spoofing gaining traction. AppsFlyer’s Real Users Lift metric further quantifies the shortfall between reported and genuine users, giving marketers a clearer picture of ROI erosion.

For marketers, the findings demand a reassessment of attribution models and stricter vetting of organic growth sources. Investing in advanced fraud‑prevention platforms that leverage machine learning, real‑time device fingerprinting, and cross‑channel analytics can mitigate the growing absolute loss. Moreover, aligning with partners who prioritize transparency—such as those highlighted in the report from adjoe, Exness, and InMobi—will become a competitive advantage as the industry moves toward more resilient, data‑driven acquisition strategies.
