ARM and PLTR at 50-Plus Price-to-Sales Revive Late-1999 Valuation Comparisons

A chorus of voices is warning that chip and semiconductor valuations have entered bubble territory, even as Nvidia reports perfect earnings. The data is stark: ARM and Palantir both trade above 50 times sales, ASTS, RKLB, ALAB, and CBRS trade at similar valuations, and smaller-cap beneficiaries of the AI boom are commanding price-to-book ratios that have no historical precedent. When asked why companies with 50 billion or higher market capitalizations trade at these multiples, the honest answer is momentumThe empirical fact that winners keep winning over the medium term., not fundamentals. This concentration of valuation premium in a narrow band of names mirrors late-1999 dynamics.

The concerns deepened when renewed scrutiny fell on Super Micro Computer (SMCI), the server manufacturer at the heart of the AI infrastructure buildout. Earlier, a striking discrepancy emerged: SMCI had reported roughly $10 billion in accounts payable that mysteriously vanished from its books in a subsequent quarter. Nvidia, as SMCI's largest supplier, reported its own earnings and provided detailed accounting, and there was no sign of the $10 billion SMCI owed for chip purchases. This mismatch raises a red flag: either SMCI's accounting is opaque or incomplete, or there was a significant reversal unaccounted for. Auditors and short-sellers are now circling.

When positioning is this one-sided, any catalyst, regulatory scrutiny, accounting restatements, earnings misses, can trigger violent mean reversion.

TSMC, the foundry backbone, also faces geopolitical risks around Taiwan and export controls on advanced nodes to China.

Defenders of current valuations argue that AI infrastructure is a multi-decade secular trend and that winners will command premium multiples for years. They point to cloud infrastructure spending curves from 2010-2020 as analogues. However, cloud beneficiaries like Amazon and Microsoft took years to reach current scale, and competition was far less intense. Today, every major tech firm is trying to build proprietary AI chips, and customer concentration risk is high. If hyperscaler capex disappoints relative to current expectations, a non-trivial risk given higher interest rates, valuation compression could be swift and brutal.
