Fact Check
The core claim is strongly supported by multiple independent sources. The Onchain Lens X post (the primary on-chain monitoring source cited in the claim) directly confirms the $250,000 USDC deposit into Hyperliquid for a 25x ETH long position on May 16. PANews (019e315b) explicitly cites Onchain Lens and confirms the same details. The 114,160 ETH position size is corroborated by PANews (019e313e) citing Lookonchain, and the swing from gains to losses is confirmed by Odaily (481939), which reports the position moved from +$13M to -$10M unrealized P&L. The only minor nuance is that the PANews/Lookonchain article describes this as a 'BIT-linked whale' rather than explicitly naming Machi Big Brother, but the position size and timing align precisely. All key claim elements - the 250,000 USDC deposit, Hyperliquid platform, 25x leverage, Ethereum long, ~114,160 ETH position size, and the gain-to-loss swing - are independently verified.
Summary

According to Onchain Lens, Machi Big Brother deposited 250,000 USDC into Hyperliquid on May 16 to add to an existing 25x leveraged Ethereum long that had grown to roughly 114,000 to 114,160 ETH. Earlier reports said the position was opened in late April around $2,270 and later expanded to an average entry near $2,268, with its unrealized performance swinging from about $13 million in gains to roughly $10 million to $10.3 million in losses as ETH fell. In a later development cited by Lookonchain, a whale opened a separate 25x leveraged ETH short worth $50.55 million and a 20x leveraged BTC long worth $25.27 million, totaling 23,151 ETH and 323.72 BTC. Lookonchain said the liquidation prices for those positions were $2,288.33 for ETH and $70,325.36 for BTC.
