Michael Burry AI Short Watch

A Santro source-gated tracker for publicly disclosed and reputable-media-reported Michael Burry bearish views on AI, semiconductor and bubble-risk names. It tracks bearish exposure, put-option reports, valuation warnings, and source-verified watchlist items — it does not claim to show a full or current portfolio.

A put option is bearish exposure, not the same as shorting stock, and a valuation warning is not a position. Santro separates the instrument, the source and the confidence level. Burry's fund (Scion) was reported wound down in late 2025; current views run through his Substack, which we treat as the primary source only when its text and date are supplied.

Hot means attention, not direction.

Bubble map — reported bearish exposure

Only source-verified items appear here. Bubble color/size reflect the ticker's current move (green up, red down) — not Burry's bearish direction. The badge shows the reported instrument (PUT / SHORT / ETF PUT / VALUATION). Where Santro has no live quote, the bubble reads “needs price verification”.

Quotes delayed ~15 min. Real-time data planned for Pro. Not financial advice.

Positions — reported bearish exposure

Verified against Scion Asset Management's SEC 13F filings (CIK 0001649339). Notional is the value of the underlying, not capital at risk, and 13Fs don't disclose strike or expiry. Scion's most recent 13F is Q3 2025 (filed 2025-11-03); no 13F has been filed since — consistent with the reported late-2025 wind-down — so these are as-of 30 Sep 2025 and the current status is not disclosed.

Needs verification

Mentioned in user-supplied notes, screenshots, or secondary discussion but needing a dated primary source (ideally the Substack) before being treated as Burry-linked active bearish positions. Not shown in the bubble map, and no reported prices/strikes are published here.

Santro read — the thesis

Why these names cluster, and what the instruments actually mean.

Semiconductor & mega-cap valuations. Burry's public argument compares AI-era valuations to the dot-com peak (Nvidia/Cisco parallels). SOXX and QQQ function as semiconductor- and Nasdaq-concentration proxies — a way to express a broad bubble view, not a single-name call.

Puts reflect timing, hedge or convex downside — not simple shorts. A put has capped loss (the premium) and an expiry; a 13F reports its notional (underlying value), which overstates capital at risk. A disclosed put is bearish exposure, not proof a manager expects a crash on a date.
Attention, not timing. A famous bear's disclosed position draws attention to valuation risk; it is not a signal of when anything happens. Pair this with Santro's AI bubble-risk index for context, and the bull side in the Aschenbrenner basket.

Source methodology

Santro prioritizes primary sources first — Substack posts supplied to the system, SEC filings and official disclosures — then reputable media as secondary verification. Social-media screenshots are treated as leads, not final evidence. If a source is missing or unclear, the ticker is marked needs verification and kept out of the bubble map. We do not invent prices, strikes, expiries, sizes or dates.
