Elon Musk and Mark Zuckerberg's companies, SpaceX and Meta, have re-entered the elite ranks of AI, challenging the dominance of OpenAI and Anthropic. Both companies recently unveiled new AI models demonstrating significant performance improvements and competitive pricing. SpaceX's Grok 4.6 performed similarly to top models, with Grok 4.7 predicted to surpass current offerings after further training. Meta is focusing on cost-effective, high-performing models, including Muse Glimmer, which can run locally. Both leaders have heavily invested in talent, infrastructure, and acquisitions to fuel their AI endeavors, with Musk integrating xAI into SpaceX and acquiring Cursor, and Zuckerberg overhauling Meta's AI efforts. The evolving AI market now values affordability alongside raw intelligence, offering a decisive advantage to companies like Meta and SpaceX. Despite these advancements, OpenAI and Anthropic maintain a lead, possessing even more capable models yet to be released. However, recent challenges at Google, including talent departures and issues with its Gemini model, present an opportunity for SpaceX or Meta to become Wall Street's leading public-market AI champion. While the frontier labs built their lead on technical excellence, Musk and Zuckerberg are leveraging their vast scale and resources to close the gap.
