Prediction market Polymarket puts the chances of SpaceX completing a stock market debut by the end of June at 52%, climbing to 87% by September and 93% by the close of 2026.

It comes as the Elon Musk-led company is said to be preparing to lodge its prospectus with the US regulator, the Securities and Exchange Commission, either imminently or in early April.

Bloomberg said SpaceX had briefed prospective investors to expect one-on-one meetings with management in the weeks following Easter, the kind of pre-marketing conversations that customarily precede a formal listing, and reported a fundraising target in the region of $75 billion, which would comfortably eclipse every previous IPO in history.

Saudi Aramco, the Saudi state oil company, set the existing benchmark when it raised just over $29 billion on its market debut in 2019.

The Wall Street Journal placed the target date for the listing at mid-June, ahead of Musk’s 55th birthday on 28 June.

The Information and CNBC reported a potential valuation of up to $1.75 trillion, more than twice the $800 billion figure attached to the company in a private fundraising round in late 2025, which would propel SpaceX into the top ten most valuable publicly listed companies globally and overtake Tesla, Musk’s electric vehicle business, by market capitalisation.

Reuters reported that Musk is seeking to reserve up to 30% of the offering for retail investors, roughly three times the standard allocation, to foster a more stable, long-term shareholder base.

SpaceX holds around 80% of the commercial rocket-launch market and runs Starlink, its satellite broadband service, with revenues growing 51% in 2024 and 18% in 2025, though the rate of expansion is easing as the business scales.

In February, SpaceX completed its acquisition of xAI, Musk’s artificial intelligence venture, in a transaction valuing the combined entity at $1.25 trillion.
