Claude by Anthropic holds overwhelming market-implied odds for the #2 free spot in the U.S. Apple App Store on June 5 because of its sustained momentum among large language model apps. The iOS app, launched earlier and rated 4.7 stars with over 162,000 reviews, has driven record sign-ups and user growth after its March surge past ChatGPT, fueled by expanded capabilities in coding, research, and complex tasks plus aggressive marketing. With ChatGPT typically locked at #1 and other AI tools or entertainment apps trailing, traders see Claude’s consistent top-tier engagement and developer ecosystem support as decisive. A major new release or unexpected viral shift could still alter rankings on resolution day, though recent Sensor Tower data shows stable positioning.
