The wind-down timeline
On Aug. 26 at 04:00 UTC, BitMEX will apply risk limits that make XBTUSD an exit-only market. Holders can reduce positions but can't add exposure. From that point until shutdown, the exchange may force-close positions at its sole discretion as part of the wind-down. At 04:00 UTC on Sept. 23, any position still open gets force-closed, and exchange services stop.
BitMEX may also route contracts with limited liquidity through early-settlement procedures after notice. That's a backstop for positions that can't be closed normally.
What's left on the books
Open interest in XBTUSD stood at 39,449,400 contracts at 01:55 UTC on Aug. 10. That's $39.45 million in face value, or about 605.45 BTC at a mark price of $65,156.99. The number covers XBTUSD only; BitMEX-wide open interest, net directional exposure, and collateral are separate measures.
XBTUSD is an inverse perpetual, each contract set at $1 of Bitcoin. Contracts don't expire during normal trading, which is why the forced closure matters for anyone still holding.
Fees after closure
Users keep limited account access to view wallet balances, transaction history, and request withdrawals. But KYC-verified users leaving assets on the platform after closure will face a monthly account-fee assessment based on the greater of $50 equivalent or 1% per year of the remaining balance. BitMEX said later fee increases would be communicated in advance.
The wind-down gives traders about six weeks to close out or reduce positions. The next hard deadline is Aug. 26, when the exit-only rules kick in.
That's about 300 words? Let's count. Actually need 450-700. Let's expand a bit. Add a sentence about the announcement date and the strategic review. Maybe a section on "Why the board moved" but we don't have facts. So we can say: The board's strategic review didn't produce a public explanation beyond the decision to wind down. That's a factual statement. But we can put it in the lead or a short paragraph. Better to have a section "The decision" with that. But we have no more. Let's add a paragraph after lead: "The decision came after a strategic review by the board of HDR Global Trading Limited, the company behind BitMEX. The exchange didn't offer a public reason beyond the wind-down itself." That's fine. Also we can mention that BitMEX will block new positions on Aug. 26 and force-close on Sept. 23. Already in lead. Let's write a bit more. Maybe add a sentence about the risk limits: "Risk limits will be applied at 04:00 UTC on Aug. 26, making XBTUSD an exit-only market." Already there. We can add a sentence about the fee structure: "The fee is based on the greater of $50 or 1% per year of the remaining balance, charged monthly." That's clear. Let's aim for 500 words. Write a few more sentences. Also need to avoid "It's worth noting" etc. Use short sentences. Let's craft final content. I'll write: Lead: BitMEX is pulling the plug on its flagship XBTUSD perpetual contract. New positions get blocked on Aug. 26, and any open interest left standing will be force-closed when exchange services end on Sept. 23. The exchange announced the wind-down on July 23, following a strategic review by the board of HDR Global Trading Limited, the company behind BitMEX. Then a paragraph: The decision came after a strategic review. The board didn't offer a public reason beyond the wind-down itself. That's all we know. Then H2: The wind-down timeline On Aug. 26 at 04:00 UTC, BitMEX will apply risk limits that make XBTUSD an exit-only market. Holders can reduce positions but can't add exposure. From that point until shutdown, the exchange may force-close positions at its sole discretion as part of the wind-down.

H2: What's left on the books Open interest in XBTUSD stood at 39,449,400 contracts at 01:55 UTC on Aug. 10. That's $39.45 million in face value, or about 605.45 BTC at a mark price of $65,156.99.

BitMEX said later fee increases would be communicated in advance. The wind-down gives traders about six weeks to close out or reduce positions. The next hard deadline is Aug. 26, when the exit-only rules kick in. That's about 350 words. Need more. Let's add a sentence about the open interest being a measure of activity. Also maybe a sentence about the announcement date being July 23, and that the wind-down is happening over two months. Also we can add a sentence about the risk limits being applied at 04:00 UTC on Aug. 26, and that the exchange may force-close at its sole discretion. Already there. Let's add a short paragraph after the lead: "The wind-down is a two-step process. First, the exchange blocks new positions and applies risk limits. Then, a month later, it force-closes whatever remains." That's a summary. Also we can add a sentence about the fee being monthly. Already. Let's write a bit more in the "What's left" section: "The $39.45 million figure is a snapshot from Aug. 10. It's the only public number BitMEX has given for XBTUSD open interest during the wind-down." But that's not in facts. We can't say that. We can say "At the time of the announcement, open interest stood at..." but we have a specific timestamp. We can say "As of Aug. 10, open interest was..." That's fine. Let's add a sentence: "The mark price of $65,156.99 puts the notional value at about 605.45 BTC." Already. Maybe add a sentence about the inverse nature: "Because it's an inverse contract, the payout is in Bitcoin, not dollars." That's factual. Let's write a final version. I'll aim for 500-600 words. Let me count words in my draft. I'll write it out. Lead: 3 sentences. ~50 words. Then paragraph: "The decision came after a strategic review. The board didn't offer a public reason beyond the wind-down itself." ~20 words. H2: The wind-down timeline (3 words) Paragraph: "On Aug. 26 at 04:00 UTC, BitMEX will apply risk limits that make XBTUSD an exit-only market. Holders can reduce positions but can't add exposure. From that point until shutdown, the exchange may force-close positions at its sole discretion as part of the wind-down. At 04:00 UTC on Sept. 23, any position still open gets force-closed, and exchange services stop." ~70 words. Next paragraph: "BitMEX may also route contracts with limited liquidity through early-settlement procedures after notice. That's a backstop for positions that can't be closed normally." ~25 words. H2: What's left on the books (5 words) Paragraph: "Open interest in XBTUSD stood at 39,449,400 contracts at 01:55 UTC on Aug. 10. That's $39.45 million in face value, or about 605.45 BTC at a mark price of $65,156.99. The number covers XBTUSD only; BitMEX-wide open interest, net directional exposure, and collateral are separate measures." ~50 words. Next: "XBTUSD is an inverse perpetual, each contract set at $1 of Bitcoin. Contracts don't expire during normal trading, which is why the forced closure matters for anyone still holding." ~30 words. H2: Fees after closure (3 words) Paragraph: "Users keep limited account access to view wallet balances, transaction history, and request withdrawals. But KYC-verified users leaving assets on the platform after closure will face a monthly account-fee assessment based on the greater of $50 equivalent or 1% per year of the remaining balance. BitMEX said later fee increases would be communicated in advance." ~60 words. Final paragraph: "The wind-down gives traders about six weeks to close out or reduce positions. The next hard deadline is Aug. 26, when the exit-only rules kick in." ~25 words. Total words: 50+20+3+70+25+5+50+30+3+60+25 = 341. Need more. Add a sentence about the announcement date in the lead? Already. Add a sentence about the strategic review in the lead? Already. Maybe add a sentence about the fee being monthly. Already. Let's add a sentence after the lead: "The wind-down is a two-step process. First, the exchange blocks new positions and applies risk limits. Then, a month later, it force-closes whatever remains." That's 3 sentences, ~30 words. Also add a sentence in the "What's left" section: "The $39.45 million figure is a snapshot from Aug. 10, the most recent public data before the wind-down." But we don't know if it's the most recent. We can say "As of Aug. 10, open interest was..." That's fine. Let's add: "The mark price of $65,156.99 puts the notional value at about 605.45 BTC." Already. Maybe add a sentence about the risk limits: "Risk limits are a standard tool for winding down a market, but BitMEX's discretion to force-close at any time is unusual." That's an opinion, not in facts. Avoid. Better to add a sentence about the timeline: "The Aug. 26 date is when the exit-only regime begins. The Sept. 23 date is when the contract dies." That's fine. Let's write a final version with about 500 words. I'll write: Lead: BitMEX is pulling the plug on its flagship XBTUSD perpetual contract. New positions get blocked on Aug. 26, and any open interest left standing will be force-closed when exchange services end on Sept. 23. The exchange announced the wind-down on July 23, following a strategic review by the board of HDR Global Trading Limited, the company behind BitMEX. The decision came after a strategic review.
