IPO Fever Returns, but the Giants May Hog It All

After several sluggish years, the market for initial public offerings (IPOs) is stirring, driven by a handful of giant deals from closely watched private technology companies.

At the center of the renewed activity is SpaceX, whose recent $75 billion offering has become an early test of investor appetite for a new wave of blockbuster listings. The company’s shares opened at $150, up 11% from the $135 offering price, and closed the first day at about $161, a gain of roughly 19%. That suggests strong interest, though not the kind of euphoric debut that once defined hot IPO markets.

The rebound extends beyond SpaceX. Cerebras, an AI hardware company, went public in May and delivered one of the strongest tech debuts in years, underscoring investor demand for AI-related offerings. At the same time, Alphabet said this month that it expects to raise about $85 billion to help finance a massive expansion of AI infrastructure. With nearly $8 trillion sitting in U.S. money market funds, there appears to be ample capital on the sidelines for new deals.

The pipeline is growing quickly. Through mid-June, market trackers showed roughly 120 IPO filings this year, putting 2026 ahead of last year’s pace and reinforcing the sense that the listing window is reopening. Behind SpaceX, several other high-profile companies are lining up, including OpenAI, Anthropic, Databricks, and Stripe.

But their arrival could create a problem for smaller issuers. The biggest names may absorb an outsized share of investor attention, analyst coverage, and risk capital, leaving less room for lesser-known, venture-backed companies to break through.

That leaves bankers and investors with a familiar question: Will mega-IPOs revive the market broadly or simply concentrate demand in a few category-defining companies? A successful run of large offerings could restore confidence and draw more issuers to market. But if most capital continues flowing to the biggest platforms, the IPO recovery may prove uneven though real.
