1.9 billion short positions + 250 million BTC sell-off: Is Wintermute genuinely shorting or hedging via arbitrage?
- Core View: On-chain data shows that crypto market maker Wintermute has significantly increased its short positions on Hyperliquid (from approximately $146 million to $190.77 million), while simultaneously transferring large amounts of BTC to Binance (approximately 3,834 BTC cumulatively this week, worth $256.8 million). This combination of "short positions + spot transfers" is seen as a key force dragging down the rebound during the weekend market pullback.
- Key Elements:
- Wintermute's short positions on Hyperliquid increased by approximately $44.58 million, mainly concentrated in major coins such as ETH ($53.02 million), BTC ($30.66 million), and SOL ($22.62 million), with long positions of only about $9.05 million.
- The related address currently has an unrealized loss of approximately $5.85 million, but its lifetime profit and loss remains positive at approximately $203.55 million, while continuing to earn funding fees.
- On-chain tracking shows that within just the past 18 hours, Wintermute transferred 1,279.99 BTC (approximately $98.68 million) to Binance through 8 transactions, with an additional approximately $57 million worth of BTC and SOL transferred to Binance and Coinbase.
- Some traders (such as MartyParty) believe this is a "market flush": triggering long squeezes by dumping spot, clearing out late-stage high-leverage longs, rather than purely directional shorting.
- Market interpretations are divided, with some observers pointing out that Wintermute's position is more likely delta-neutral funding rate arbitrage or inventory hedging, rather than a directional short bet.

TechFlow Intro: On-chain data shows that crypto market maker Wintermute has rapidly increased its short position on Hyperliquid from approximately $146 million to $190.77 million, adding roughly $44.58 million in new shorts concentrated in major coins such as ETH, BTC, and SOL.
Meanwhile, the firm has transferred a cumulative total of 3,834.3 BTC, worth approximately $256.8 million, to Binance this week. The related address is currently sitting on an unrealized loss of about $5.85 million, though its lifetime P&L still exceeds $200 million in profit. Against the backdrop of a weekend market pullback, this combination of "short positions + spot transfers" is viewed by some traders as a key force weighing on the rebound.
On-chain data tracking platform Onchain Lens reported on August 23 that the short exposure of a Wintermute-related address (0xecb63caa47c7c4e77f60f1ce858cf28dc2b82b00) on Hyperliquid has further expanded. Previously, this address held approximately $160.03 million in open positions, with $146.19 million in shorts and only $13.85 million in longs. The latest data shows shorts have risen to $190.77 million, with total exposure of approximately $199.81 million. The unrealized loss has widened from $3.66 million to $5.85 million, while the address continues to earn funding fees.
Hyperliquid Short Position Grows from $146M to $191M
Onchain Lens monitoring indicates that Wintermute has been continuously injecting funds into Hyperliquid and adding to its short positions. Since the last update, the short size has increased by approximately $44.58 million. The current top five short positions are:
- ETH: ~$53.02 million
- BTC: ~$30.66 million
- SOL: ~$22.62 million
- HYPE: ~$11.43 million
- XRP: ~$10.19 million
Screenshot data shows this address holds only approximately $9.05 million in longs, indicating an extremely high short ratio. Despite the current unrealized loss of $5.85 million, the address's lifetime P&L remains at approximately $203.55 million in positive territory. Onchain Lens directly asked in its update: "What is their CEX perpetual position worth now?"
This position buildup comes against the backdrop of a noticeable market pullback over the weekend. BTC had previously approached $80,000 before retreating, with ETH, XRP, and others also following the decline.
Cumulative Transfer of 3,834 BTC to Binance This Week
Around the same time, Wintermute's large transfers to centralized exchanges have also drawn attention. MartyParty noted on August 22 that Wintermute had deposited another 590.9 BTC (approximately $45.66 million) into Binance about an hour prior. This brings the firm's cumulative transfers to Binance this week to 3,834.3 BTC, worth approximately $256.8 million.
Further monitoring by Onchain Lens shows that within just the past 18 hours, Wintermute transferred 1,279.99 BTC to Binance across 8 transactions, worth approximately $98.68 million, with the latest transfer of 90.1 BTC completed about 30 minutes ago. Other data also mentions that the firm has transferred a combined total of approximately $57 million in BTC and SOL to both Binance and Coinbase.
MartyParty linked this series of operations to a market "flush": "Last night's sell-off was clearly Wintermute's doing... It's simple for them — wait for the leveraged perpetual market to start long cascades, then dump spot to trigger long squeezes, clear out late-stage high-leverage longs, and open up room."
Hedging Arbitrage or Directional Shorting?
Market interpretation of this is not uniform. Some observers believe that as a top market maker, Wintermute's positions are more likely delta-neutral funding rate arbitrage or inventory hedging rather than purely directional shorts. One user replying to Onchain Lens's post directly pointed out: "Their position on HL is not directional — it's just delta-neutral funding arbitrage."
Market makers routinely need to allocate inventory between CEX and DEX, hedge risk, and provide liquidity as part of daily operations. Large transfers to exchanges do not necessarily equate to an imminent sell-off. However, the simultaneous expansion of short positions and spot transfers, combined with the weekend price pullback, has still led some traders to associate the two, believing this intensifies long liquidation pressure and acts as a "stumbling block" to the current rebound.
As of now, the related address's short exposure on Hyperliquid remains elevated, and the pace of transfers to Binance has not shown significant signs of slowing. How the market digests these positions and inventory allocations in the coming period will require continued monitoring of both on-chain and CEX data.
