A record 13 publicly listed companies now carry market capitalisations exceeding USD 1 trillion, a milestone that reflects both the extraordinary concentration of value in a small group of globally dominant corporations and the outsized role that technology and artificial intelligence-driven businesses have come to play in equity markets worldwide. The figures, recorded as of April 23, 2026, show Nvidia holding the top position by a considerable margin at USD 4.93 trillion, a valuation that would have been difficult to imagine even three years ago before the artificial intelligence infrastructure boom propelled the chipmaker to the forefront of the global economy.
Nvidia is followed by Google parent Alphabet at USD 4.12 trillion and Apple at USD 4.02 trillion, with all three companies clustered in the USD 4 trillion range and collectively representing more economic value than most national economies. Microsoft sits fourth at USD 3.13 trillion, while Amazon rounds out the top five at USD 2.78 trillion. The presence of semiconductor companies Broadcom at USD 2.03 trillion and Taiwan Semiconductor Manufacturing Company at USD 2 trillion in the top seven underscores how foundational chip manufacturing and design infrastructure has become to global technology valuations, with investors pricing in sustained demand for the hardware that powers artificial intelligence workloads at scale.
The lower half of the trillion-dollar club reflects the breadth of sectors now capable of sustaining valuations at this level. Saudi Aramco, the world’s largest oil producer, sits at USD 1.76 trillion, representing the continued financial weight of energy despite accelerating global transitions toward alternatives. Meta Platforms follows at USD 1.69 trillion, Tesla at USD 1.41 trillion, Walmart at USD 1.04 trillion, and Berkshire Hathaway at USD 1.01 trillion. Samsung Electronics, the South Korean electronics and semiconductor giant, rounds out the list at exactly USD 1 trillion, making it the thirteenth member of a group that has expanded significantly over the past several years as sustained market appreciation has lifted technology and energy valuations to levels previously uncharted in financial history.
What is particularly notable about the current composition of this group is the degree to which it is dominated by companies whose valuations are directly or indirectly tied to the artificial intelligence supply chain, from chip designers and manufacturers to cloud platform providers and consumer technology companies embedding artificial intelligence across their product ecosystems. The concentration of this much market value in this few companies, and in this narrow cluster of interconnected technology domains, has become one of the defining structural features of global equity markets in the mid-2020s, raising questions among analysts about valuation sustainability even as the underlying demand for artificial intelligence infrastructure continues to grow.
