Machi Big Brother Liquidates 25x ETH and 40x BTC Longs Amid Market Slide

According to Onchain Lens, Machi Big Brother’s Hyperliquid positions deteriorated from a massive 25x ETH long to renewed liquidation pressure, while Lookonchain later reported separate opposing ETH short and BTC long whale trades with unclear attribution.

Fact Check
All key elements of the claim are directly confirmed by multiple independent sources. The Onchain Lens X post (status/2055315029453578351) is the originating primary source and explicitly states: 25x ETH longs closed, 40x BTC longs closed, ~$32M total losses, ~$10M remaining positions. This is corroborated verbatim by Odaily (newsflash/481794), PANewsLab, and Bitget News, all published on 2026-05-15. A follow-up Odaily report (newsflash/481888, 2026-05-16) adds that both positions were fully liquidated and Machi reopened a new ETH long, which is consistent with the claim that 'roughly $10 million in positions remain open.' The specific leverage multiples (25x ETH, 40x BTC), the loss figure (~$32M), and the remaining position size (~$10M) are all consistently reported across sources. The minor residual uncertainty (5%) reflects the fact that on-chain monitoring data, while highly reliable, is interpreted by a third-party tracker rather than a direct statement from Machi himself.
Summary

According to Onchain Lens, Machi Big Brother deposited 250,000 USDC into Hyperliquid on May 16 to support an existing 25x leveraged ETH long that had reached roughly 114,000 to 114,160 ETH, after earlier being opened in late April around $2,270 and later averaged near $2,268. The trade’s unrealized performance reportedly swung from about $13 million in gains to roughly $10 million to $10.3 million in losses as ETH fell. Earlier, he also closed most of his 25x ETH long and 40x BTC long as markets declined, with cumulative losses nearing $32 million and about $10 million in positions still open. A newer update says he is again facing liquidation after more than two weeks: his account balance has fallen to $85,000, total losses have reached $31.99 million, and his remaining holdings are 1,275 ETH worth $2.77 million, with a liquidation price of $2,152.96. Separately, Lookonchain later reported a whale opening a $50.55 million 25x ETH short and a $25.27 million 20x BTC long totaling 23,151 ETH and 323.72 BTC, but the available source material does not explicitly confirm that those positions belong to Machi Big Brother.
