Crypto Sleuths Eye 13F Filings for Clues to October 10’s $19 Billion Crash

The crypto market is still reeling from the October 10, 2025, crash—a historic bloodbath that obliterated over $19 billion in leveraged positions in just 24 hours. As questions linger about what triggered this catastrophe, all eyes are on the upcoming Q4 2025 Form 13F filings, due February 17, 2026, which could reveal whether a major institutional player or hidden financial giant played a role in the chaos.

• Historic Crash: October 10 saw $19 billion in leveraged positions liquidated, the largest single-day event in crypto history.
• 13F Filings: SEC disclosures due February 17, 2026, might show institutional Bitcoin ETF sell-offs tied to the crash.
• Wild Theories: Speculation ranges from TradFi giants to an Asia-based non-crypto entity as potential culprits.

The October 10 Meltdown: A Market in Freefall

On October 10, 2025, the crypto market didn’t just stumble—it faceplanted. Bitcoin’s price plummeted, while altcoins took even harsher beatings, as over $19 billion in leveraged positions (borrowed funds used to amplify potential gains or losses) were forcibly closed within a single day. This wasn’t a mere dip; it was a liquidation cascade, a brutal chain reaction where falling prices trigger margin calls, forcing automated sales that drive prices even lower. Retail traders woke up to wiped-out portfolios, and even seasoned players were left shell-shocked by the speed and scale of the destruction. Months later, the cause remains a mystery, with social media platforms like X erupting in theories ranging from geopolitical shocks to shady exchange practices.

What Are 13F Filings, and Why Do They Matter to Crypto?

Enter Form 13F filings—quarterly reports required by the U.S. Securities and Exchange Commission (SEC) for institutional investment managers handling over $100 million in U.S. equity assets. These disclosures, due within 45 days of a quarter’s end, detail long positions in stocks and exchange-traded funds (ETFs), including Bitcoin spot ETFs like BlackRock’s IBIT. For the uninitiated, Bitcoin spot ETFs allow traditional finance (TradFi, meaning conventional institutions like banks and hedge funds) players to bet on Bitcoin’s price without directly owning the cryptocurrency, lowering the barrier for big money to dip into crypto waters. The Q4 2025 filings, covering the period of the October 10 crash, are set for release on February 14, 2026—Valentine’s Day, though pushed to February 17 due to a weekend and Presidents’ Day. While the date might inspire romantic quips, the stakes for crypto traders seeking answers are anything but sweet.

The hope is that these filings will uncover a missing piece of the $19 billion puzzle. Could a heavyweight TradFi player, overexposed to Bitcoin via ETFs, have been forced to dump their holdings, sparking or worsening the crash? X users and industry watchers are buzzing with speculation, as many crypto natives hope upcoming 13F filings will provide clarity on October 10’s events, though some caution against expecting a clear revelation. As one X user, TheOtherParker, noted, even if a fund liquidated a massive ETF position post-crash, the change might not be disclosed until later quarters, potentially delaying answers until mid-May 2026.

“Unfortunately, if a fund had their IBIT position liquidated today, they wouldn’t have to disclose the position change until 45 days after the quarter end, so we’d be looking at mid-May for the smoking gun from 13F filings most likely.” — TheOtherParker, X User

Institutional Culprits: Bitcoin ETFs in the Crosshairs

The rise of Bitcoin spot ETFs has been a game-changer, drawing billions from institutional investors into crypto markets. These funds, like BlackRock’s IBIT, have ballooned in size, offering a regulated bridge for TradFi to gain exposure without navigating the wild west of direct crypto ownership. But this bridge swings both ways—while it legitimizes Bitcoin in the eyes of Wall Street, it also imports TradFi’s volatility. A sudden sell-off by a major player could send shockwaves through crypto, especially in a market already juiced on leverage. If the 13F filings show a significant reduction or disappearance of Bitcoin ETF holdings from a big name around the crash date, it could point to a panic sale as a key trigger.

Yet, let’s not get ahead of ourselves. Even if the filings reveal a sell-off, correlation isn’t causation. Other factors—macroeconomic pressures, geopolitical flare-ups, or even unrelated market dynamics—could have ignited the October 10 fire. Plus, 13F filings only capture a snapshot of long positions at quarter’s end; they miss intraday trades, short positions, and derivative plays that might tell a fuller story. We’re grasping for clues, but the picture may remain frustratingly incomplete.

Asia-Based Mystery: A Shadowy Non-Crypto Giant?

Not all theories point to TradFi ETF holders. Franklin Bi, General Partner at Pantera Capital, has suggested a different suspect: a large non-crypto entity, possibly based in Asia or Hong Kong, operating in near-total isolation from crypto-native networks. This could explain why no whispers of their involvement have leaked through the gossip mill of crypto Twitter (CT), a space where rumors of collapses usually spread like wildfire.

“Someone large outside of crypto, likely based in Asia, with very few crypto-native counterparties,” could be the culprit, explaining “why no one has sniffed them out on CT.” — Franklin Bi, Pantera Capital

This idea has gained traction, with X users like TheOtherParker reinforcing that a non-crypto fund’s lack of ties to the space would keep their actions off the radar. If true, this theory highlights a blind spot in crypto’s hyper-connected community: the growing influence of external players who don’t play by our rules—or even know them. But without concrete data, this remains pure speculation, and if the entity isn’t subject to U.S. reporting requirements, the 13F filings won’t shed any light.

Binance Under Fire: Centralized Exchanges in the Spotlight

Closer to home, accusations are flying at centralized exchanges, with OKX’s CEO publicly blaming Binance for mishandling risky positions, potentially fueling the liquidation cascade. Binance, no stranger to controversy, has long been a lightning rod for criticism in the crypto space. While no hard evidence ties them directly to October 10, the narrative of distrust persists, especially given the sheer volume of leveraged trading on such platforms. Centralized exchanges are often the weak link in a market that prides itself on decentralization, acting as choke points where over-leveraged bets can spiral into systemic disasters. Whether Binance is culpable or just an easy scapegoat, the finger-pointing underscores a broader tension: crypto’s reliance on centralized infrastructure clashes with its ethos of financial freedom.

Comparing Crashes: Why October 10 Feels Different

Industry voices aren’t all quick to pin blame. Evgeny Gaevoy, CEO of crypto market maker Wintermute, doubts the crash stemmed from a typical exchange or market maker blowup. Unlike past disasters—think Three Arrows Capital (3AC) in 2022 or FTX’s collapse—there’s no visible domino effect, no rapid spread of panic through backchannels and DMs that usually signals a major player’s downfall.

“Maybe somebody blew up but there are simply no spillover effects for us to care. When 3AC blew up post terra everyone knew fairly soon because it spread via DMs. Sure it was shock and disbelief at first but it lasted maybe 2-3 days all in all.” — Evgeny Gaevoy, Wintermute CEO

Gaevoy also points to the absence of bailout or investment talks, often a telltale sign of distress. When FTX imploded, murmurs of Binance stepping in as a savior were a glaring red flag. This time, the eerie silence suggests either a very different kind of crisis—or one so insulated that its ripples haven’t reached us yet.

“You don’t talk about bailouts/investments unless there is something very wrong.” — Evgeny Gaevoy, Wintermute CEO

Compare this to the May 2021 crash, driven by China’s mining ban, where liquidations hit hard but causes became clear within days. October 10 stands out for its lingering opacity, raising questions about whether crypto has matured in its ability to absorb shocks or simply grown more fragmented and harder to read.

The Bigger Picture: Bitcoin’s Image and Decentralization at Stake

Beyond the whodunit, October 10 is a gut punch to Bitcoin’s narrative as a safe store of value. When billions vanish in a day, it’s hard to pitch crypto as a stable alternative to fiat systems, especially to newcomers or skeptical institutions. The irony isn’t lost on us: as TradFi pours in via ETFs, bringing legitimacy, it also drags in baggage—volatility, opacity, and systemic risks that Bitcoin was meant to escape. This crash lays bare the tension between mainstream adoption and the raw, rebellious spirit of decentralization. Are we building a freer financial future, or just repackaging Wall Street’s flaws in blockchain wrapping?

Let’s not forget the human cost. While data on retail versus institutional losses from October 10 is scarce, it’s safe to assume countless small-time traders bore the brunt, caught in a storm they couldn’t predict or control. If crypto is to fulfill its promise of empowerment, events like this must push us toward more resilient, peer-to-peer systems, not deeper entanglement with centralized exchanges or TradFi instruments.

What’s Next for Crypto Resilience?

As February 17, 2026, approaches, the crypto community braces for the 13F filings with a mix of hope and hard-nosed realism. These SEC reports might hint at a TradFi titan’s role in the October 10 carnage, or they might leave us empty-handed, grasping at shadows of an Asia-based fund or exchange misconduct. Either way, the truth—or a sliver of it—will surface eventually. Until then, let’s scrutinize every theory, from ETF sell-offs to mysterious outsiders, with a hefty dose of skepticism.

More importantly, let’s learn from this mess. Bitcoin and blockchain tech are still our best shot at disrupting a broken financial status quo, but crashes like October 10 remind us the road is littered with potholes. If we’re serious about decentralization, we need fewer over-leveraged gambles, less reliance on centralized choke points, and more focus on building systems that don’t buckle under pressure. Will events like this accelerate our push for true financial freedom, or are we doomed to mimic TradFi’s worst impulses in crypto form? Time, and perhaps a few SEC filings, will tell.
