What happened?
Two things landed on the same day, July 23. First: a proposed class action was filed against the BitMEX exchange and its co-founders, among them Arthur Hayes. Second: BitMEX announced it would cease operations. This coincidence is the main thread of the whole story, but it is important to keep both events separate for now, because the sources do not confirm they are directly connected.
A proposed class action is a lawsuit brought by one or several plaintiffs on behalf of a wider group of affected parties; the court still has to decide whether to certify it as a class action.
What does the lawsuit accuse BitMEX of?
According to The Defiant, the lawsuit was filed on July 23 and accuses the exchange of two main things:
- that it kept client collateral seized during position liquidations,
- that it ran an internal trading desk with access to confidential data on user positions.
Cointelegraph adds that the lawsuit concerns 623 BTC and claims BitMEX used privileged trading access and server freezes to profit from forced liquidations.
Liquidation means the exchange forcibly closes a trader's leveraged position when their collateral is no longer sufficient to cover losses. It is precisely these forced closures that sit at the heart of the dispute.
For now these are claims made by the plaintiffs, not proven facts. The court has not ruled on the matter, and BitMEX's response to the specific points of the lawsuit does not follow from the sources.
When and how is BitMEX shutting down?
According to CryptoSlate, BitMEX, the Seychelles-based exchange founded by Arthur Hayes, announced on July 23 that it would cease operations. The wind-down timeline, per the same source, looks like this:
| Date and time (UTC) | What happens |
|---|---|
| July 23 | Announcement, new registrations halted |
| August 26, 04:00 | Risk limits take effect; users can only reduce positions |
| September 23, 04:00 | Final shutdown; open positions will be closed |
CryptoSlate points to an important detail: although clients were given roughly two months to close positions and withdraw funds, the real window for active trading is shorter. From August 26 positions can only be reduced, and during the wind-down BitMEX reserves the right to forcibly close contracts.
Who is behind the decision and why?
According to the Slovak site Kryptonovinky.sk, the parent company HDR Global Trading is behind the end of the exchange, justifying the decision with a strategic reassessment of the business without giving more specific reasons. According to the same source, the exchange assured users their funds remain safe and urged them to withdraw.
Where do the sources contradict each other?
There is one contradiction we do not want to hide. CryptoSlate lists the final shutdown as September 23 (two months after the July 23 announcement, i.e. the year 2025). Kryptonovinky.sk, on the other hand, writes about operations ending on September 23, 2026. So the sources diverge on the year, and from the summaries alone it is not possible to determine unambiguously which is correct. We present both versions and mark the date as uncertain.
What to watch out for with this type of event
This is not advice on what to do with your money. It is a list of things that can be objectively tracked with closing exchanges and lawsuits:
- Exact withdrawal deadlines. Risk limits and the trading deadline may arrive before the final shutdown.
- Official exchange announcements, not just media summaries, to confirm dates and procedures.
- The progress of the court proceedings: whether the court certifies the lawsuit as a class action and how BitMEX defends itself.
- Differences between sources (see the date contradiction above) as a signal that it is worth waiting for a primary source.
Charliedesk will follow this matter and update it as soon as primary documents (the text of the lawsuit, the official wind-down schedule) or a court decision become available.
