June 15th, 2026: Walmart Delivers Subway, CaaStle Fraud, Apple and Siri AI, and Shopify and AI

She told investors $440M. The real number was $15.7M. This week: the CaaStle fraud, Walmart's Subway play, and Shopify's $5B bet.In this episode:Walmart + Subway. Walmart folded Subway into its delivery app, with express orders coming off the Subway counters already sitting inside its stores. Live now in six states (Connecticut, Florida, Georgia, Ohio, Pennsylvania, Texas), with roughly 1,400 locations targeted by end of summer. Flat delivery fee, in-store menu pricing, 30 minutes or less. It rides on the Spark drivers and drones Walmart is already paying for, pointed straight at Uber Eats and DoorDash.The CaaStle fraud. CaaStle told investors it booked $440 million in net revenue for fiscal 2023. The real figure was $15.7 million. Founder and CEO Christine Hunsicker confessed to doctoring the financials on a video call with her board in December 2024, then kept her job for three more months while investors heard nothing. She controlled that board. Co-founder Jaswinder Pal "JP" Singh sold $6 million in stock back to the company around the time investors started asking questions. Hunsicker pleaded guilty to securities fraud in March, admitting she defrauded investors of $283 million, and she's scheduled for sentencing this summer.Apple rents the brains. At WWDC on June 8, Apple introduced Siri AI: a rebuild that reads what's on your screen, pulls context from your messages and email, and takes actions across apps. The part Apple said less about is who's powering it. Reporting puts Apple at more than $1 billion a year to Google for a custom Gemini model running Siri's cloud features. The China rollout waits on regulators. For a company that has spent decades insisting it owns its entire stack, renting the model from a rival is the real headline. Tim Cook hands the company to John Ternus in September.Shopify's $5 billion vote. Shopify added $3 billion to its repurchase program on June 2, taking total authorization to $5 billion. Buybacks usually get read as "we've run out of ideas." Then Q1 revenue rose 34% to $3.2 billion and merchants cleared $100 billion in GMV for the second quarter in a row. Decide for yourself which signal you believe.
