The milestone came as it agreed to buy the startup behind the AI-powered coding app Cursor for $60bn (£44bn), in an attempt to capitalise on the technology’s success as a coding tool. SpaceX is the parent of Musk’s AI business, xAI, which will be able to boost its capabilities in an area – AI systems writing code – that has proven to be a strong commercial success for Anthropic, the rival company behind the Claude chatbot.

The news of the Cursor acquisition was announced as SpaceX passed Amazon in market capitalisation, an important measure of value for a publicly listed company. SpaceX shares rose by 13% on opening on the Nasdaq index on Tuesday. At one point, its valuation rose as high as $2.97tn, leaping over Amazon’s $2.65tn to become the world’s fifth most valuable company . Its shares later eased back to about 5% up at the close and a valuation just ahead of the e-commerce company of $2.66tn. SpaceX lost $4.9bn in 2025 on revenues of $18.7bn, while Amazon posted revenues of $717bn and net income – a US measure of profit – of $78bn. SpaceX floated at $135 a share on Friday and its shares have risen by approximately 50% since. The float made Musk, SpaceX’s founder and chief executive, the world’s first trillionaire with a fortune of $1.1tn, according to Forbes. It reckons the 54-year-old is now worth $1.3tn. The company had been circling Cursor, owned -based Anysphere, for months. It said in April it had secured an option to ‌either buy Cursor for $60bn later this year or pay $10bn for a partnership.
