Funds & institutional holders
SEC 13F putsNamed funds disclosing a PUT position against this ticker in their most recent SEC 13F-HR filings, matched on CUSIP rather than issuer name (a multi-filer filing can carry an unrelated company's name over the right CUSIP) and attributed to the filer named in that filing's own primary document. This is a quarterly snapshot filed up to 45 days late, so the position may already be gone. A put can be a hedge on a long position, not a directional bearish bet. And 13F excludes short stock outright, which is how most short interest is actually expressed, so this is a small, self-selected slice of the bearish side shown alongside the aggregate short interest above, never an explanation of it. Absence from this list is not evidence a fund is not short.

What a squeeze costs
Model, not a predictionA size check, not a forecast: how much net buying it would plausibly take to move the price by a given amount, using the square-root market-impact law ΔP/P = Y·σ·√(Q/ADV) (Almgren et al. 2005; consistent with Kyle's lambda). Y = 1 here, a commonly-cited value for the impact coefficient, exposed as a named constant rather than baked in. σ is trailing daily volatility over the last 65 trading days; ADV is average daily volume. None of this knows anything about actual short entry prices, margin calls, or borrow availability. It is a mechanical answer to "how big a trade moves this how far", nothing more.

The square-root law is fitted to trades that are a fraction of one day’s volume. Extrapolated to the larger moves above it asks for more shares than have ever been issued, which is arithmetic rather than a market outcome. Those targets are marked, and should be read as “further than this model can see” rather than as a price.

Options & gamma exposure
Options & gamma exposure
CBOE, delayedFeed quote time 2026-09-03 22:16:11. This is delayed data, not a live tape. Cached 3 Sept 2026, 22:37 UTC. Spot used for these figures: $15.22.
Gamma exposure is an intraday, mechanical hedging flow: how many shares a delta-hedged options book would need to trade for a 1% move in the underlying, computed from today's open interest and the venue's own per-contract greeks (no Black-Scholes re-derivation here). It is a different mechanism from the short-interest days-to-cover model above, which plays out over days on a figure that only updates a couple of times a month. Treat these as two separate stories, not one combined "squeeze" number.
Every "net" figure below assumes dealers are net short the calls and net long the puts their customers hold. That is a common convention (SqueezeMetrics' GEX methodology; the assumption most retail options-flow trackers use), which makes call gamma an accelerant on the way up (+1) and put gamma an offsetting term (-1). This is an assumption about who is on the other side of the open interest, not a disclosure. Nobody publishes actual dealer books. The raw, unsigned call and put totals are shown alongside the net figure so a reader who rejects the assumption still has usable numbers. Open interest also names nobody: unlike the 13F table above, options data cannot show who wrote a contract at all (13F itself never covers short stock either, see the caveats on that table).

Gamma-flip strike: Not reported: no sign crossing in this chain
The strike where cumulative net gamma (summed from the lowest strike up, under the same sign convention) crosses zero, if the chain has one. This is a fragile marker, not a level: it depends on every assumption above, moves with which strikes and expiries happen to sit in the chain, and can shift meaningfully between one feed pull and the next on thin or stale quotes near the crossing. Read it as a rough boundary, not a price target.

The token runs
A meme paired to the stock catches a bid and brings people with it.

The arb passes it on
The tokenized share is arbitraged against the listed one, so the buying lands there.

Shorts feel it
A crowded short gets more expensive to hold the higher it goes.
Steps one and two are the parts anyone here controls. Steps three and four are the bet. A meme token has no claim on the stock, the two prices can drift apart for as long as they like, and a short position can stay open longer than a group chat stays interested.
