Behind Wall Street’s plunge: AI liquidation threatens Anthropic’s mega-IPO

A broad selloff sent the Nasdaq 100 down as much as 6% and the S&P 500 down as much as 3.8% Thursday, as investors liquidated AI infrastructure stocks and reduced risk across sectors. The selling raises doubts about Anthropic’s reported potential IPO of about $100 billion at a $1.5 trillion-plus valuation; its filing showed Q3 revenue of approximately $16.96 billion, a $23.29 billion net loss, and $895.4 billion in aggregate purchase commitments and leases. The article also reports Walleye Capital plans to return some client capital, while clarifying that this alone is not evidence of distress.

Analysis

The key risk is a financing feedback loop, not proof that AI demand has rolled over: falling equity values can raise the cost of capital for capacity builders, delaying delivery and weakening the economics of suppliers and customers in turn. The most exposed layer is leveraged, execution-dependent infrastructure—especially operators whose build plans precede firm utilization and cash generation. Chip demand can remain strong while those operators’ equity and credit deteriorate; demand alone does not ensure timely, financeable capacity.

An IPO valuation or size reset would be a near-term sentiment catalyst, but treating one offering as a referendum on every AI business would be an overreach. Strong software revenue does not by itself demonstrate returns sufficient to cover large, long-dated compute commitments. Conversely, a smaller or delayed offering could reflect market windows and dilution discipline rather than a collapse in demand. The reported Walleye capital return is a positioning signal, not evidence of distress; broad de-risking can nevertheless amplify crowded-trade selling.

Over days to weeks, expect elevated correlation and possible forced selling; over 1–3 months, watch IPO terms, infrastructure financing spreads, delivery timelines, and hyperscaler capex guidance. Over 6–18 months, the differentiator is utilization and returns on deployed capacity. Microsoft is not insulated: slower third-party capacity delivery could constrain AI product rollout, while lower infrastructure costs could eventually benefit its economics. Thesis weakens if financing remains available on stable terms, delivery milestones are met, and monetization supports capex without weaker guidance.

Key Decisions for Investors

• Avoid buying the infrastructure dip mechanically. For a tactical risk-off expression, consider a defined-risk SMH put spread rather than an outright short; size modestly given the likelihood of sharp reversals. Reassess after IPO terms and financing conditions are clearer.
• Prefer a relative-value screen over a blanket AI short: compare infrastructure-heavy exposure with cash-generative platform businesses, but do not assume MSFT is a pure hedge because it also depends on AI capacity and continued investment. Require confirmation from capex guidance and capacity-delivery commentary before establishing a pair.
• Treat ANT’s offering as a catalyst, not a standalone valuation signal. Monitor formal price range, proceeds, demand/coverage, lockups, and post-listing trading; a material scale or valuation reset would support further caution across capital-dependent infrastructure, while a well-supported deal would challenge the bearish positioning thesis.
• Track credit spreads and refinancing access for data-center and compute-capacity providers, alongside utilization, construction milestones, and customer commitments. Widening spreads or repeated delivery slippage would validate the downside case; stable financing and improving utilization would falsify it.
