Key Takeaways:
Prediction markets now give Anthropic a 63 percent chance of surpassing SpaceX's record $85.7 billion IPO as the largest public debut of 2026.
Prediction markets now assign Anthropic a 63 percent probability of unseating SpaceX as the largest IPO of 2026, after the AI start-up's annualized sales surged from $9 billion to $65 billion in seven months.
"The average year-one max drawdown for the 30 hottest tech-driven IPOs over the past 14 years is 55 percent," according to data compiled by Truist Financial, a pattern already visible in SpaceX's 54 percent peak-to-trough decline from its post-debut high.
SpaceX raised $85.7 billion from its public debut, including the underwriters' overallotment, nearly tripling the previous record for an IPO cash raise. The company was valued at $1.77 trillion when it priced approximately 555.6 million shares at $135 each. Anthropic's annual run rate sales jumped from about $9 billion at the end of 2025 to $65 billion by the end of July, according to Bloomberg data.
If Anthropic prices at a $2 trillion valuation, it would trade at more than 30 times annualized sales — a level no leading technology company has sustained over an extended period. The stakes extend beyond the two companies: a successful Anthropic debut could open the floodgates for AI-related listings, while a post-IPO slump would reinforce the historical pattern of hot tech IPOs disappointing retail investors.
Polymarket traders assigned almost no chance of Anthropic unseating SpaceX four weeks ago, according to the prediction market. The shift followed Bloomberg's report that the developer of the Claude large language model had seen its annual run rate sales catapult from around $9 billion at the end of 2025 to $65 billion by the end of July. Kalshi, the other major prediction platform, has similarly shifted its odds in Anthropic's favor.
Anthropic counts Meta Platforms and Microsoft among its high-profile recurring clients. The company is also backed by Amazon and Alphabet, whose stakes total approximately 21 percent and 14 percent, respectively. These strategic relationships provide both revenue visibility and a distribution channel for Claude across enterprise and consumer platforms.
When SpaceX debuted, it traded at north of 100 times its reported 2025 full-year sales. History shows that no company at the forefront of a major technological trend has sustained a price-to-sales ratio above 30 over an extended period. Even based on its current annual run rate, Anthropic would fall firmly in this historical bubble territory.
Every major technology cycle over the last three decades has experienced an early-stage bubble-bursting event. These bubbles eventually burst because investors persistently overestimate the pace of adoption and optimization of new technologies. While spending on AI infrastructure is off the charts, businesses are likely several years away from optimizing AI solutions. The last comparable cycle — the dot-com boom of the late 1990s — saw the Nasdaq Composite fall 78 percent from its March 2000 peak, with many high-flying IPOs losing more than 90 percent of their value.
Truist Financial's data shows the average year-one max drawdown for the 30 hottest tech-driven IPOs over the last 14 years is 55 percent. SpaceX's peak-to-trough drawdown from its post-debut high is already 54 percent. While retail investor buzz surrounding IPOs can be intense, it rarely lasts more than a few weeks.
The historical record is clear: chasing hot tech-driven IPOs rarely works in retail investors' favor. Even though prediction markets expect Anthropic to rewrite Wall Street's history books, the data suggests retail investors would be wise to keep their distance.
For institutional investors, the calculus differs. A $2 trillion Anthropic listing would rank among the largest companies in the S&P 500 by market capitalization, potentially triggering significant index inclusion flows. But for retail investors, the asymmetry between the hype cycle and the historical drawdown data remains stark.
