Bitcoin News Today: Bitcoin Whale's $420M Short Challenges Record ETF Inflows

A prominent Bitcoin "OG" whale has executed a $420 million short position on the decentralized exchange Hyperliquid, leveraging $80 million in USDC collateral at a 6X leverage ratio. The trade, revealed by blockchain analytics platforms Arkham and Lookonchain, involves 3,477 BTC and carries a liquidation price of $140,660. The whale simultaneously transferred $50 million to Binance, suggesting a hedging strategy across exchanges. This move follows the whale's prior sale of 3,000 BTC ($363.87 million) just two days earlier, signaling a bearish outlook amid Bitcoin's recent all-time high of $126,198 on October 6, 2025.

The trade has triggered immediate market reactions. Bitcoin's price dipped below $120,000 post-disclosure, according to CoinMarketCap data, with the asset currently trading at $120,300. The whale's position is currently $660,000 in profit, though its success hinges on Bitcoin remaining below $140,660. Analysts note that the whale's strategy could involve a dual-exchange approach, with the trader potentially balancing long positions on centralized exchanges to offset the short. Lookonchain's analysis suggests the whale anticipates a "massive dump" in BTC price, though market dynamics remain uncertain.

Derivatives data from Coinglass reveals a mixed sentiment landscape. While the whale's aggressive short contrasts with a still-positive Bitcoin OI-weighted funding rate of 0.0043% (as of October 9), long liquidations ($121 million in 24 hours) outpace short liquidations ($63 million). This indicates lingering bullish bias among traders, despite the whale's bearish bet. Meanwhile, Bitcoin spot ETFs have recorded eight consecutive days of inflows, according to SosoValue, which may counterbalance bearish pressures.

The whale's actions have reignited debates about market structure and regulatory scrutiny. Hyperliquid's transparency-enabling real-time tracking of large positions-has drawn both praise and criticism. The platform highlighted the trade as an example of decentralized trading's "future," asserting that public visibility of whale activity fosters accountability. However, critics argue such transparency may incentivize coordinated "whale hunts," as seen in previous attempts to liquidate leveraged positions. A user identified as CBB (formerly associated with crypto firm Celsius) rallied traders to push Bitcoin higher, though efforts to liquidate the whale's position failed after the trader added $5 million in USDC to reinforce the short.

Historically, OG whales-long-term holders active since Bitcoin's early days-have played pivotal roles in market cycles. This whale's recent moves align with broader patterns of portfolio diversification. Earlier in October, the entity sold 35,991 BTC to acquire ether, reflecting a strategic shift toward Ethereum. Analysts caution that while short-term volatility is likely, Bitcoin's long-term structure remains intact, with key support levels at $118,000 and $112,000 acting as critical benchmarks.

Regulatory and macroeconomic factors further complicate the outlook. The U.S. Federal Reserve's upcoming FOMC meeting and evolving inflation data could sway investor sentiment. Fumihiro Arasawa of xWIN Research notes that easing inflation-evidenced by February's lower-than-expected 2.8% CPI-may support Bitcoin's trajectory, though a breakdown below $81,000 could trigger further corrections. Market participants are closely monitoring whether institutional demand and ETF inflows can offset bearish bets.
