The deprecation of third-party cookies, long delayed but now completed across all major browsers, has fundamentally altered the affiliate marketing landscape in iGaming. Players can no longer be tracked seamlessly across publisher sites, forcing affiliates to rethink how they measure, attribute, and optimize traffic.
The affiliates best positioned heading into 2026 are those who invested early in first-party data infrastructure: email lists, on-site behavioral data, registered user databases, and direct relationships with operator CRM teams.
"Affiliate programs that relied on cookie-based last-click attribution are already seeing their reported conversions drop," said industry strategist Helena Borg. "The underlying traffic hasn't disappeared — the measurement has broken."
The shift is accelerating consolidation, with larger affiliate groups acquiring smaller players who have strong owned audiences but lack the technical resources to build proper data pipelines.
For operators, the message is clear: the value of affiliate partnerships is increasingly determined by content quality, SEO authority, and registered user bases rather than raw traffic volume.
