Could One of the AI Giants Reignite the IPO Fires in 2026?

Some of the world’s most closely watched private companies may be edging closer to the public markets.

OpenAI, Anthropic and SpaceX are widely rumored to be exploring potential initial public offerings (IPO) as soon as this year—offerings that would rank among the largest in history and could reshape the IPO landscape.

The timing may finally be turning favorable. After years of caution, market conditions for IPOs are improving following a series of interest-rate cuts by the Federal Reserve since September 2024. Investors increasingly view 2026 as a potential inflection point for new listings, particularly at the upper end of the market.

The scale of these potential IPOs reflects both investor enthusiasm and necessity. Capital demands for businesses at the center of artificial intelligence and aerospace are immense, ranging from data center buildouts and advanced computing infrastructure to rocket launches and satellite networks. For companies operating at this level, access to public capital markets may eventually become less a strategic choice than a practical requirement.

Despite strong public market performance—nearly 20% annualized returns in the S&P 500 since 2023—IPO issuance has lagged. While 2025 marked the strongest year for new listings in the past three years, volumes remained well below prior cycle peaks, underscoring the reluctance of many private firms to go public.

A successful mega IPO could help change that dynamic. History suggests that high profile offerings often act as catalysts, reopening the IPO window for other private companies. But the rapid rise of AI may reshape that dynamic. While the technology promises productivity gains and new growth opportunities, it also poses structural challenges to established software and services businesses.

A risk of concentration also exists. Just as a small group of giant tech stocks has dominated public markets, a handful of major AI players could command a disproportionate share of investor attention. In this environment, selectivity will be critical. The companies most likely to stand out are those that either supply the infrastructure behind AI or use the technology to fundamentally transform how their industries work.
