Veteran short seller Jim Chanos has raised fresh doubts over SpaceX’s impending public market debut, arguing that the aerospace company’s proposed valuation is based on “hopes and dreams” rather than near-term financial fundamentals, according to a report by Reuters.
SpaceX is preparing for a blockbuster IPO in New York, targeting a valuation of approximately $1.75tn in what would be the largest listing in history, significantly exceeding the scale of Saudi Aramco’s 2019 flotation.
Speaking at an investment conference in New York, Chanos said he does not believe the company’s valuation is justified under reasonable projections for the next several years. He characterised the pricing as being driven more by narrative expectations than by measurable financial performance.
The SpaceX offering is expected to raise around $75bn and has drawn intense attention from both institutional investors and market strategists, with debate centring on whether the company’s long-term ambitions in space infrastructure can support such a substantial valuation.
Chanos, founder of Kynikos Associates and one of the most prominent figures in the short-selling community, suggested that investor enthusiasm is being fuelled by speculative themes around future space-based industries, including orbital infrastructure and interplanetary expansion.
He argued that such projections risk overshadowing current fundamentals, noting that high-growth narratives can dominate market pricing during bullish cycles, even when underlying earnings visibility remains limited.
While some analysts have floated the idea that SpaceX could become a short candidate at launch, many hedge funds remain cautious about positioning against the stock given the scale of momentum and the historical losses associated with shorting high-growth technology leaders.
Chanos declined to confirm whether he would take a short position, but reiterated his scepticism regarding the valuation framework being applied by investors.
The discussion also touched on broader concerns within the technology sector, particularly around capital-intensive infrastructure businesses such as data centre operators. Chanos has previously argued that such firms often resemble low-return utility-style models rather than high-margin technology platforms, due to depreciation costs, pricing pressure and reliance on external hardware suppliers.
He suggested that in some cases, these businesses may be mispriced relative to semiconductor manufacturers that control key parts of the value chain.
Chanos, who gained prominence for his early identification of accounting issues at Enron, has long been a high-profile critic of speculative excess in equity markets, particularly during periods of strong risk appetite.
