Investors have been warned to be wary of cashing in their shares in order to pile into SpaceX’s record-breaking stock market float this week.

Elon Musk’s rocket firm will list in New York with a valuation of £1.3 trillion in the world’s biggest ever initial public offering (IPO).

UK investors have been told they have until Wednesday evening to apply for shares and thousands have already been visiting investment platform websites to find out how to participate.

Market watchers fear the SpaceX IPO, together with forthcoming mega-floats by artificial intelligence (AI) firms OpenAI and Anthropic, could see investors dump other holdings.
