After approximately 10 days of experiencing Meta's AI agent Muse, veteran independent stock analyst Mostly Borrowed Ideas (MBI) liquidated his heavily weighted Airbnb stock and increased his position in Meta. MBI believes that Muse will disrupt the business models of internet aggregation platforms such as Airbnb, Booking, Uber, DoorDash, and Amazon, ushering in an era of "proactive e-commerce."

MBI shared that Muse can accurately recommend accommodations by combining users' historical lodging experiences and social media content, and can book directly, bypassing Airbnb, at prices up to 60% cheaper. He believes that AI agents can build trust by scraping reviews across the entire internet and help hosts manage multiple platforms, dismantling the "exclusive supply" barrier. MBI contrasted this by stating that Booking's valuation is only 10-11 times EBITDA, significantly lower than Airbnb's 30 times, and its customer acquisition costs may decrease due to AI, making it more resilient.

Furthermore, MBI pointed out that Amazon faces a crisis with its $76 billion advertising business, as AI agents will rationally seek the optimal solution across the entire internet rather than clicking on ads. For Uber and DoorDash, he believes the impact will come slightly later, but Uber faces the risk of a brutal price war driven by autonomous driving and AI price comparison.
