Can Laravel handle the load for a high traffic mobile app?

Yes. Laravel powers backends for mobile applications serving millions of monthly active users in production today. Laravel Octane (with Swoole or FrankenPHP), Redis caching, Horizon queues, and Vapor or AWS deployment scale Laravel backends horizontally to handle large traffic. We have shipped mobile backends sustaining 50,000 plus concurrent users with P95 response times under 150ms. The honest summary: Laravel is rarely the bottleneck for mobile backends, the database or third party integrations usually are.
