The ranking of the world’s wealthiest people in September 2026 continues to be shaped by the artificial intelligence boom, with technology fortunes swelling and shifting as investors bet heavily on the sector. Elon Musk remains at the top, his wealth anchored in Tesla and SpaceX and increasingly tied to his AI venture.
The founders of Alphabet have seen their fortunes climb as the company weaves its Gemini artificial intelligence into commercial services and cloud infrastructure. Jeff Bezos continues to benefit from Amazon’s cloud division, which has gained fresh momentum from surging demand for AI computing.
Others are positioned differently. Mark Zuckerberg’s wealth reflects Meta’s push into custom chips and open source AI models, while Warren Buffett has taken an unusually defensive stance, holding large reserves in government securities and trimming equity exposure ahead of possible turbulence.
Alice Walton remains the wealthiest woman in the world, her fortune rooted in Walmart’s steady dividends and its expansion into e-commerce and automated logistics. The picture underlines how the current wave of wealth creation is concentrated among those closest to the technologies driving the moment.
