Anthropic's IPO Could Be the Biggest Ever, But It Has $518B in IOUs

Anthropic is reportedly meeting prospective investors ahead of a potential IPO before Thanksgiving, with analysts floating the possibility it becomes the largest public debut in history, topping even SpaceX's private valuation. That's the hype. Here's the hangover: per CNBC's Big Technology correspondent Alex Kantrowitz, Anthropic carries approximately $518 billion in compute and infrastructure obligations, with 80% reportedly non-cancellable. That's not a balance sheet. That's a hostage situation with better branding.

The bull case is genuinely compelling. Bloomberg Podcasts covered Jensen Huang's point that Anthropic and OpenAI are the fastest-growing tech companies in history, with real revenues and profitable token economics. Seeking Alpha separately flagged that Broadcom is arranging $42 billion in debt financing specifically for Anthropic's infrastructure buildout, which either signals institutional conviction or the most expensive vote of confidence since SoftBank and WeWork. Broadcom's own quant rating is a strong buy with a PEG ratio of 0.56 and 75.5% gross margins, so at least one side of that trade looks clean.

The bear case comes from the bond market, which is rarely wrong about this stuff. BondCliQ's Chris White flagged on CNBC that AI-linked companies have issued approximately $258 billion in debt over the past 12 months, creating a supply glut that is already pushing credit spreads wider. Newly issued AI bonds are trading significantly wider just six months after issuance, which White calls highly abnormal. CoreWeave, the AI infrastructure cautionary tale of the week, already has bonds trading below 80 cents on the dollar, a threshold associated with financial distress, and its debt matures in 5-7 years, making it acutely sensitive to the current rate environment.

Venture capitalist Bradley Tusk summarized the mood on CNBC succinctly: AI euphoria is fading because markets now want real revenue, positive EBITDA, and returns on capital. Tusk explicitly favors application-layer AI companies over infrastructure and frontier model builders because they can generate cash without the burden of buying GPUs or building data centers. Anthropic, by definition, is neither of those things.

What makes the Anthropic IPO uniquely interesting is that it forces the entire market to price something it has never had to price before: a frontier AI lab with stratospheric revenue growth, an existential compute dependency, and a business model that requires the AI buildout to never, ever slow down. If Jensen Huang is right that token costs are falling 30 to 40 times per year, Anthropic's economics get better over time. If Meredith Whitney is right that AI capital spending is masking deep economic fragility, the timing of this IPO will look like ringing the bell at exactly the wrong moment.

The IPO market is already structurally broken, per Warburg Pincus CEO Jeffrey Perlman, with 60% fewer public companies than a decade ago. Anthropic going public would be a genuine test of whether the market can absorb the AI era's defining company, or whether it's just another way to let retail investors fund the infrastructure bill that venture capital no longer wants to carry alone.
