How can you measure an AI bubble with credit instead of stock prices?

Short answer: Watch the debt that pays for AI data centers, not the share prices. Stress in credit shows up in how lenders, funds and borrowers behave: loans going soft, funds capping withdrawals, financing getting pulled. Glitch in the Credit turns that into one daily number from 0 to 100. On Oct 27, 2026 it read 50, Elevated, down 2 from 52 on Oct 26, 2026, with 2 of 6 layers flashing: weakest borrowers and funds. It reports what the readings show. It doesn’t predict anything, and it isn’t advice.

What’s the difference between an AI stock bubble and an AI credit bubble?

A stock bubble is about the price people pay to own a company. A credit bubble is about whether the money borrowed to build things can be paid back. Share prices can fall without a single lender losing money, and a loan can sour while a share price holds up. Many AI data centers are paid for with borrowed money, so the second question matters for the people who lent it and for the funds that hold those loans.

Which credit signals show stress first?

Glitch in the Credit watches six layers, in the order a squeeze tends to travel. The order is our working model, not a law.

1. Collateral loses value. The chips and buildings behind the loans. Signals: GPU rental prices; Hyperscaler lease pullbacks.
2. Weakest borrowers crack. Signals: Neocloud stocks; Neocloud bonds; Customer concentration; Delayed projects.
3. Loans quietly go soft. Signals: PIK interest share; Amend-and-extend deals; Marks vs market prices.
4. Funds feel pressure. Signals: Redemption gates; Public BDC discounts; Credit default swaps.
5. Plumbing tightens. Signals: Pulled deals; Bank lines to funds; Downgrades and insurer exposure.
6. People behave strangely. Signals: Senior departures; Late filings, auditor changes, restatements.

The signal that matters most is the chain reaction: collateral, weakest borrowers and funds all flashing at once. One flashing light isn’t news. The combination is the signal.

What does the index say today?

As of Oct 27, 2026, from the daily check:

The overall index is 50 of 100, Elevated (down 2 since Oct 26, 2026). The chain reaction is not complete: two of its three links are flashing, and collateral is calm. The first check with an index value was Oct 26, 2026, at 52. Daily history is at the archive.

How is the 0 to 100 number built?

Each of the 17 signals is graded calm (0), watch (1) or flashing (2) every morning from news, filings and data feeds, and each reading links its source and date. A layer averages its signals: 1.5 or higher is flashing, 0.75 or higher is watch. The index averages the six layers on a 0 to 100 scale, in five bands: Quiet (0 to 19), Stirring (20 to 39), Elevated (40 to 59), Warning (60 to 79), Panic (80 to 100). Full method: how it works.

Government data sits behind several readings: the OFR Financial Stress Index (US Treasury), the Federal Reserve Board’s excess bond premium, Fed bank lending data from FRED, and filings from SEC EDGAR.

What can’t this tell you?

• It doesn’t tell you when anything will happen. It isn’t a timing tool.
• Some readings are judgment calls based on public reporting, some of it secondhand or unconfirmed. Each reading links to its source so you can check.
• It doesn’t tell you what to buy, sell or hold.
• It started on Oct 25, 2026, so there’s little history yet.
