SpaceX, the leading force in the space industry, is preparing for a June initial public offering, generating significant buzz among investors. The company holds a dominant position in orbital launches, and its Starlink satellite internet service has outpaced competitors such as Amazon's Project Kuiper. SpaceX's innovative reusable rocket technology and ambitious ventures into space tourism and direct-to-cell internet further bolster its growth narrative.
However, the company's recent financial performance raises red flags. SpaceX reported a net loss of $5 billion, largely attributed to heavy investments in AI infrastructure. This loss, combined with a valuation that could reach $2 trillion, has led some analysts to caution that public market gains may be limited. The stock is already held in prominent funds like Schiehallion (LSE: MNTN) and Scottish Mortgage, which have benefited from its private market appreciation.
Investors considering buying SpaceX stock in their ISAs or other accounts should weigh these factors carefully. The company's growth potential is undeniable, but the high valuation and recent losses suggest that the IPO may not offer the same upside as earlier private investments. Caution is advised as the IPO date approaches.
Beyond SpaceX, the broader IPO market is showing signs of revival, particularly in the fintech sector. After a steep decline in 2022 and 2023, fintech IPOs rebounded with 14 listings in 2024 and 31 in 2025. Companies like Chime, Circle, eToro, and Klarna are driving this resurgence, with over 200 fintech unicorns, including Stripe and Revolut, poised to go public. However, the market remains selective, favoring firms with clear earnings and operational strength. Broader IPO success hinges on mega tech listings such as OpenAI, Anthropic, and SpaceX itself.
In the defense sector, contractors like RTX (NYSE:RTX) reported strong Q1 earnings, with revenues beating consensus by 3.4%. RTX posted $22.08 billion in revenue, up 8.7% year-on-year, but its weak full-year guidance caused shares to fall 8.1%. Mercury Systems (NASDAQ:MRCY) outperformed, with revenue up 11.5% and shares surging 38.6%. The sector benefits from steady government contracts amid geopolitical tensions but remains sensitive to defense budget shifts.
Meanwhile, POET Technologies (NASDAQ:POET) saw its shares rise 65% in the past month and 121% over three months, driven by AI infrastructure demand. The stock closed at $13.26, below an analyst-estimated fair value of $17.37, suggesting it remains undervalued. POET's optical interposer technology enhances data transfer speeds, differentiating it from GPU-focused firms. Backed by partners like Foxconn and a $250 million investment, POET targets rapid growth despite ongoing net losses.
Ultra-wealthy families are also adjusting their portfolios, holding only 34% in equities and allocating heavily to private companies (15.8%), private equity, and real estate. Private firms like SpaceX remain private longer, offering alternative growth opportunities. Vehicles like the Schiehallion Fund (LSE: MNTN) provide exposure to these assets through publicly traded shares, though volatility remains a concern.
Inflationary pressures, dubbed "Trumpflation," continue to impact stock market valuations. President Trump's tariffs on unfinished imports have raised production costs and consumer prices, with the Supreme Court striking down some tariffs but new global tariffs being imposed. Geopolitical tensions, including military actions against Iran, are unsettling investors. Inflation remains above the Federal Reserve's 2% target, challenging the sustainability of current bull market gains.
As the IPO landscape evolves, investors must navigate a complex environment of high valuations, sector-specific risks, and macroeconomic headwinds. SpaceX's IPO represents a landmark event, but thorough due diligence is essential before committing capital.
