SEC Files Back-to-Back Securities Suits Against Binance and Coinbase

The SEC opened a two-front legal offensive against the crypto industry's two largest exchanges within 24 hours. On Monday, the agency filed charges against Binance, its founder CZ, and affiliate BAM Trading Services Inc. The next day, Coinbase was named in a separate complaint. A long list of tokens — including SOL, ADA, MATIC and ATOM — were also swept in, labeled as unregistered securities across the two filings. Both companies have signaled they intend to contest the charges rather than settle.

Two very different cases

The Binance complaint is by far the more expansive of the two, reflecting what the SEC describes as a pattern of the exchange skirting US rules while concentrating its business offshore. The charges span operating an unregistered securities exchange; offering unregistered securities, including Binance's own BNB and BUSD tokens (with the classification tied to how the stablecoin was marketed for yield-generating uses) and its staking programs; failing to prevent market manipulation, including wash trading allegedly carried out by CZ-owned Sigma Chain; encouraging US-based customers to register as if they were offshore and to use VPNs; and commingling customer funds across entities. Notably, the complaint includes an internal quote attributed to Binance's own Chief Compliance Officer: "we are operating as a fking unlicensed securities exchange in the USA bro." The SEC has also asked the court to freeze Binance's corporate assets to prevent funds from leaving US jurisdiction.

The Coinbase complaint, by contrast, is narrower: operating an unregistered securities exchange (again naming a similar roster of tokens) and offering unregistered securities through its staking programs. Coinbase has pushed back hard on the framing, stating it met with the SEC for guidance 30 separate times in 2022 without resolution. When the company received its Wells notice in March, it had already been waiting eight months for a response to its rulemaking petition asking the agency to clarify which digital assets qualify as securities. Having received no answer, Coinbase sued the SEC in April to force a reply. According to Coinbase's chief legal officer Paul Grewal, the SEC now has seven days to say whether it is denying that petition — a timeline that sits awkwardly next to the agency's enforcement action and its usual refrain that companies should simply "come in and register." The suit also landed just hours before Grewal was scheduled to testify before Congress on crypto rulemaking and the Digital Asset Market Structure Discussion Draft. Critics have also noted the SEC permitted Coinbase to go public and operate for years while its guidance requests went unanswered — during a period when the US government itself reportedly used the exchange to sell crypto holdings — making the timing of enforcement look inconsistent, as some have pointed out. Coinbase has since moved to establish an international exchange outside the US.

The token list and its implications

Combined, the two complaints named BNB, BUSD, SOL, ADA, MATIC, FIL, ATOM, SAND, MANA, ALGO, AXS, COTI, CHZ, FLOW, ICP, NEAR and NEXO as securities. Bitcoin and most proof-of-work tokens were left untouched, as was Ether — an omission many had expected the agency to eventually revisit. By targeting native tokens of competing layer-1 networks, particularly SOL and MATIC, the SEC may be laying groundwork for a broader argument that could later be extended to ETH. The approach also pressures other platforms that list these tokens — Robinhood, for instance, had already moved to delist several assets preemptively, a decision that likely fed into a broader sell-off in altcoins the night the news broke. Ahead of both announcements, some traders appeared to position themselves with suspicious timing, and separately, opportunistic scammers breached BNB Chain's Discord to run a phishing scheme during the confusion.

How each exchange has responded

Binance said in a blog post that it would contest the case, even as reporting indicated the company had previously explored a settlement — a detail that doesn't help its position. CZ's own reaction was terser: a one-word tweet reading "4," followed by a poll questioning Gensler's track record. Binance has also alleged that Gensler personally approached the exchange back in 2019 offering to serve as an advisor. Regardless of the rhetoric, Binance US has already taken concrete steps: it first removed 40 trading pairs from its platform, and banking partners have since forced it to pause USD deposits, with withdrawals expected to follow.

Coinbase CEO Brian Armstrong struck a calmer tone, posting: "Btw, in case it's not obvious, the Coinbase suit is very different from others out there – the complaint filed against us is exclusively focused on what is or is not a security. And we are confident in our facts and the law." That narrower framing arguably puts Coinbase in a stronger legal position: the SEC's case against it hinges almost entirely on how "security" gets defined, with no allegations of the kind of internal misconduct that surfaced in Binance's own compliance messages.

Reading the bigger picture

Taken together with coordinated actions from ten state regulators, the two cases look less like a coherent regulatory framework and more like a broad enforcement push. Some have questioned whether this represents Gensler trying to reassert authority after the SEC failed to catch the FTX collapse beforehand — notably, Binance had postured itself as a stabilizing force in crypto's aftermath, and its role in FTX's downfall may not have gone unnoticed by regulators. Whatever the motivation, in the absence of tailored legislation, enforcement action remains the SEC's primary tool against an industry it can't otherwise contain. For centralized exchanges, some degree of regulatory clarity is arguably necessary given their role bridging crypto and fiat, but the US regulatory environment continues to prove difficult for crypto firms to navigate — in contrast to jurisdictions in Europe and Asia, where regulatory frameworks are further along, even if imperfect.

From a DeFi perspective, the fallout from this clash between regulators and centralized platforms could push more users toward decentralized alternatives — though, as some have cautioned, a multisig wallet is not the same thing as true resilience. Coinbase appears positioned to fight this out fully, potentially cementing a role for regulated CeFi as an intermediary layer between traditional finance and on-chain crypto. Binance, for its part, has reiterated in its blog post that it "intend[s] to defend [its] platform vigorously" — a more substantive commitment than CZ's one-word tweet suggested.
