The distinction between sharing that requires consent and sharing that is deemed 'necessary for the contract' is important, as the latter can occur without your explicit agreement.
Ticketmaster collects extensive personal data including contact details, payment information, location, browsing behavior, health/accessibility information, and government-issued ID for secondary market sellers, sharing it broadly with event partners, commercial partners, advertising networks, and fraud screening providers. Profiling and personalization activities are conducted by default, meaning your purchase history and behavior are used to build a user profile. You can opt out of marketing and personalization through your Ticketmaster account settings, and California residents and EU/UK users have additional rights to request data deletion or portability.
