Binance's Reversal Seals FTX's Collapse After a Chaotic 72-Hour Bank Run

For much of the recent bull cycle, FTX and Alameda Research operated with limited scrutiny. A branding built around "effective altruism," heavy political lobbying, and a favorable market meant that the pair's aggressive market conduct drew little sustained criticism. That changed once it became apparent the two firms were losing money even while operating under rules seemingly designed to favor themselves.

Sam Bankman-Fried's image had already begun to sour within the crypto community after a period spent positioning himself as a go-between for regulators and lawmakers. Following the release of his proposed framework for digital-asset regulation, he responded to criticism with public pushback, appeared to struggle when defending the positions he'd taken, and traded jabs with rivals over who held more sway in shaping regulatory capture. With allegations now surfacing of a roughly $10 billion shortfall, his run at the center of the industry's attention has come to an abrupt end — likely to be remembered by supporters of crypto's founding ideals as a betrayal, and by the industry more broadly as one of its costliest setbacks.

01An opaque partnership unravels

The financial relationship between FTX and its sister trading firm Alameda Research was never fully transparent. Together, the two ran an arrangement in which Alameda farmed yield using FTT as collateral, while backing numerous layer-1 chains and their surrounding app ecosystems — many built on tokenomics that favored insiders. Given the scale of this arrangement, one might have expected it to be highly profitable. Instead, nobody anticipated just how much damage would surface once the numbers were exposed — a reckoning that one rival was positioned, motivated, and equipped to trigger.

Binance CEO Changpeng "CZ" Zhao's campaign against FTX played out with precision, whether or not it was planned in advance. Shortly after reporting surfaced that Alameda's balance sheet was heavily weighted toward FTT, CZ moved. The opening step was revealing that Binance still held more than half a billion dollars in FTT tokens obtained the prior year as part of Binance's exit from its FTX equity stake. Although CZ maintained the goal was to "minimise market impact," the implication was unmistakable: raise doubts about Alameda and FTX's solvency, invoking memories of the Terra/Luna and Celsius failures.

Alameda's newly installed CEO, Caroline Ellison, may have compounded the damage by responding too soon. After initially pushing back on concerns about the balance sheet, she offered — less than two hours later — to buy out Binance's FTT position at $22 per token. That figure effectively handed the market a reference price to trade against, and FTT came under sustained selling pressure as FTX and Alameda scrambled for liquidity. FTX's hot wallets were replenished from other exchanges, Circle, and Alameda itself, but no meaningful cold storage reserves could be found. CZ made sure to highlight the contrast by tweeting about the size of Binance's own reserves amid the turmoil.

02Withdrawals, denials, and a scramble for cash

SBF initially dismissed growing concern over withdrawals and solvency as "a bunch of unfounded rumours." FTX's official account later attributed processing delays to banks being closed for the weekend — an explanation that only generated further skepticism, particularly once it emerged that at least one wallet appeared able to withdraw funds without difficulty while other users were blocked.

Reports then surfaced that SBF was seeking a bailout after more than $6 billion had exited the exchange over a 72-hour span — undercutting SBF's earlier (since-deleted) reassurances. The unfolding thread and the silence that followed mirrored the final days of Terra/Luna and Celsius, when Do Kwon urged holders to "steady lads" and Alex Mashinsky dismissed concerns as "FUD and misinformation."

03A rescue deal, then a reversal

After a stretch of paused withdrawals, SBF broke the silence with an announcement: events had come "full circle," with Binance — FTX's original investor and the source of its FTT holdings — agreeing to acquire the exchange. CZ confirmed a potential takeover was under discussion, but stressed the offer was non-binding, contingent on full due diligence, and that "Binance has the discretion to pull out from the deal at any time." For a few hours, it looked as though a resolution had been reached.

That relief proved short-lived. Citing either the shortfall turning out larger than expected — reportedly around $10 billion — or new information about mishandled customer funds, Binance announced it was withdrawing from the acquisition:

As a result of corporate due diligence, as well as the latest news reports regarding mishandled customer funds and alleged US agency investigations, we have decided that we will not pursue the potential acquisition of FTX.com.

Reports suggested the deal had reportedly been contingent on Binance also acquiring FTX US alongside the insolvent international entity — a condition US regulators were unlikely to ever permit. Whether CZ's exit reflected a genuine miscalculation or a convenient public-relations narrative (blaming regulators removes blame from Binance for attempting the deal at all, as CZ himself suggested) is unclear. Another reading is that CZ never intended to close the deal, and instead used the offer to pressure SBF into a public admission of failure before walking away.

04Ripple effects and open questions

The immediate fallout is expected to hit Alameda-linked tokens hardest, with ecosystems such as Solana exposed through FTX/Alameda-controlled wrapped assets. The consequences of the FTX/Alameda unwind already appear to extend well beyond the companies' own sphere.

Throughout the crisis, figures at FTX and Alameda repeatedly downplayed, disbelieved, rejected, and minimized what was happening. If the allegations of misappropriated user deposits are confirmed, those responsible could face criminal liability. Separately, on-chain activity pointing to a possible bailout sent to Alameda in the aftermath of the Three Arrows Capital collapse appears to be the transaction SBF earlier described in a tweet as merely "rotating a few FTX wallets" — a characterization that now looks understated, especially given that FTX's lawyers reportedly resigned around the same period.

As the scale of the shortfall became clearer, the once-unlikely theory that FTX had used customer deposits improperly gained credibility. Leaked internal messages reportedly show SBF stating that refunding customers was his priority — but that framing sidesteps the more basic problem that those deposits should never have become unbacked in the first place.

It's also worth asking why SBF, while running a firm in this condition, had spent recent months actively courting closer regulatory oversight. Was it simply optics, an attempt to project legitimacy through apparent cooperation? Or was mounting pressure from the ongoing SEC inquiry — since joined by the Department of Justice — a factor in his public embrace of regulation? Whatever the motive, his earlier willingness to work within the traditional regulatory system now reads as ironic, particularly as the SEC continues targeting DAOs and DeFi projects while a licensed, centralized platform ran what looks like a conventional financial fraud.

05SBF's account and CZ's aftermath

In a subsequent Twitter thread, SBF characterized FTX as illiquid rather than insolvent, attaching a vague disclaimer about volatility. He said he was still piecing together the full picture, apologized, and attributed the situation to a math error and poor communication on his part. He said he intended to try to recover users' funds but could not guarantee an outcome. The thread closed by acknowledging Binance's decisive countermove — and despite CZ's own claim that there had been no coordinated "master plan," the sequence of events left Binance in a dominant market position.

CZ has since positioned himself as an advocate for transparency, calling on exchanges to publish proof-of-reserves attestations — a push that appears to be gaining traction — and summarizing FTX's failures in two points:

1: Never use a token you created as collateral.

2: Don't borrow if you run a crypto business. Don't use capital "efficiently". Have a large reserve.

Elsewhere, other figures tied to earlier collapses resurfaced during the fallout — from Do Kwon being told by Martin Shkreli on the UpOnly show that "jail's not that bad," to reflections from Andre Cronje, to a since-criticized analogy from Zhu Su about watching people struggle without intervening, alongside his comments on losing a sense of purpose. Meanwhile, some withdrawals reportedly began processing again on FTX, though possibly limited to certain favored addresses.

06The regulatory question this raises

The opacity on display throughout this episode mirrors the traditional finance system that crypto was originally built to route around. If FTX did in fact lend out roughly half of customer deposits to support Alameda's trading activity, that would constitute a breach of FTX's own terms of service — a document the exchange has previously disregarded in a separate dispute over deposit fees. Unlike Celsius, whose terms explicitly permitted customer funds to be used for yield generation, FTX's terms state:

Title to your Digital Assets shall at all times remain with you and shall not transfer to FTX Trading. ... None of the Digital Assets in your Account are the property of, or shall or may be loaned to, FTX Trading; FTX Trading does not represent or treat Digital Assets in User's Accounts as belonging to FTX Trading.

None of this argues against penalizing custodial exchanges that break the law or mishandle funds — that accountability is warranted. But it's a case for confining stricter regulatory scrutiny to centralized, custodial platforms like FTX, rather than extending that same framework to self-executing, transparent DeFi protocols that operate on fundamentally different terms. Applying jurisdiction-bound, legacy-style rules to decentralized systems doesn't protect users the way recent events suggest is needed — if anything, this episode is an argument for reducing reliance on any single corporate intermediary, including Binance, regardless of how financially sound it claims to be, and including other centralized players such as Justin Sun. Placing funds with any custodial exchange means trusting a profit-driven entity — a risk that looks the same to depositors whether the platform's stated motivation was greed or "effective altruism."
