The 13F Stopped 7 Months Ago — Here Is What Burry's Substack Has Disclosed Since

The 13F stopped at Q3 2025 but the Substack hasn't — Burry has rolled his PLTR puts several times, added to SOXX puts, and opened a new short on May 4.

---

Michael Burry's last publicly filed 13F is dated September 30, 2025. Seven months have passed with no new filing (Q4 2025 and Q1 2026 are missing). Over the same period he has posted daily on his Cassandra Unchained Substack. While the 13F is stale, the Substack is real-time data.

Here we compile Burry's short and put positions as of May 11, sourced only from what he himself disclosed on the Substack. Three posts are the source.

1) Palantir (PLTR) puts — rolled several times since fall

I have been short Palantir since the fall, through puts as expressed in two articles: Palantir's New Clothes and Palantir: An Accounting. I have rolled these several times. I now own the June 17, 2027 Strike Price 50 Puts and the December 18, 2026 Strike Price 100 Puts. I am not selling these today.

Michael Burry — Cassandra Unchained, April 10, 2026 (Trade Alert)

Currently held PLTR puts (two):

• $50 strike, June 17, 2027 expiry

• $100 strike, December 18, 2026 expiry

Both still held per his own words. After several rolls since fall 2025, the puts have settled to these strikes and expiries.

2) New Palantir short — established May 4

Right after the Q1 earnings print, Burry opened a new short on May 4. He confirmed it the next day:

Shares collapsed, down $10.12 to $135.91. I continue to hold my short position, established yesterday. Below is a 1 month chart of Palantir stock — it is selling off in the after-hours a bit more as I write this.

PLTR fell ~7% after Q1 earnings. Burry entered short just before the drop and explicitly confirmed he is "continuing to hold" while watching the after-hours fade further.

3) Semiconductor ETF (SOXX) puts — added May 4

First, tending to the shorts. I added to my SOXX January 2027 Strike 330 Puts in the $14s. Even the logarithmic chart looks stretched. What a rally, a true cherry on top of a decade+ explosive run.

Michael Burry — Cassandra Unchained, May 4, 2026 (Trading Post)

iShares Philadelphia Semiconductor ETF (SOXX) January 2027 $330 strike puts, added at the $14 price range. He used "added to" to make the size increase explicit. The buy came with the SOX index up ~224% since the 90-Day Pause.

Why looking only at the 13F is wrong

Burry's last 13F (Q3 2025, Sep 30) lists these option positions:

• PUT PLTR — $912M (66% of book)

• PUT NVDA — $186M (13.5%)

• CALL PFE — $153M (11.1%)

• CALL HAL — $61M (4.5%)

Those are the numbers everyone quotes on social media. But more than six months have passed and Burry himself has said he "rolled several times." Current exposure is different from the 13F numbers — expiries differ, strikes differ, and a new name like SOXX has been added.

Two likely reasons for the missing Q4 2025 and Q1 2026 13Fs:

1) Scion Asset Management's AUM dropped below the $100M 13F threshold (exempting him)

2) Confidential-treatment request filed with the SEC — a common move among activists and short-sellers

Either way, the conclusion is the same: while waiting on the 13F, you have to read the Substack to know Burry's actual book.

How Inteliview handles this

In compiling this post we built a new data structure called GuruDisclosedPosition. Anything a guru personally discloses outside the 13F — Substack, X, interviews, podcasts — is tracked separately with a mandatory public source URL on every entry so readers can verify the original.

On Burry's page (/guru/michael-burry) you can see both the 13F positions and the Substack-disclosed positions. The 13F is old; the Substack updates daily.
