The latest wave of blockbuster private-market financing is accelerating expectations that some of the biggest names in artificial intelligence and deep tech may soon test Wall Street’s appetite. Bloomberg reports that SpaceX is seeking to raise $75 billion in a record-breaking initial public offering, a move that could open the door to more mega-listings from companies such as Anthropic and OpenAI, which are widely expected to target multibillion-dollar debuts of their own.
That momentum is already showing up across the broader market for high-growth technology names. Ramp, the fintech company, raised $750 million at a $44 billion valuation, nearly tripling its value over the past year, according to TechCrunch. The deal underscores how investors are rewarding startups that can pair fast growth with an AI narrative, even as public-market valuations remain far more cautious in many other sectors.
The frenzy around artificial intelligence is also shaping the way investors talk about the economics of these companies. In reporting around Anthropic’s runway toward a possible IPO, TechCrunch said the company’s annualized revenue crossed $47 billion in May, up sharply from about $9 billion at the end of 2025. At the same time, Business Insider noted that OpenAI chief executive Sam Altman recently described AI costs as a “huge issue” for some companies, a reminder that the sector’s growth story is still being tested by the expense of training and running advanced models.
Public markets are not just focused on AI. Quantinuum, a quantum computing company backed by Honeywell, made its Nasdaq debut this week and briefly jumped before closing little changed after raising $1.68 billion in an upsized U.S. IPO, according to Bloomberg. Fast Company described the listing as a closely watched debut in a niche but strategically important field, while Wired said quantum computing is having its public-market moment even though many of these companies are still losing money.
Elsewhere, investors are showing continued interest in tech businesses tied to defense, space, and strategic infrastructure. Planet Labs raised its full-year outlook after reporting record quarterly sales driven by defense and government demand for earth-imaging services, Bloomberg reported. Bloomberg also said China’s semiconductor rally could extend further on the back of upcoming blockbuster IPOs and technology breakthroughs, highlighting that the public-market push is global, not limited to U.S. AI firms.
The bigger picture, according to analysts and conference speakers quoted across these reports, is that investors are willing to tolerate high valuations and heavy spending if they believe a company sits at the center of a major technological shift. That belief is now pushing everything from AI startups to quantum computing and chipmakers toward public-market or near-public-market milestones, with the next several months likely to determine whether this remains a financing boom or becomes a full-scale IPO race.
