BREAKING
Known DeFi whale Machi Big Brother (@machibigbrother) has expanded his leveraged long book to $131 million across three assets as broader crypto markets push higher, according to on-chain tracking by Lookonchain. The position data is verifiable in real time via Hypurrscan.
The sizing is notable not only for its scale but for its concentration: three assets, all long, no hedges visible on-chain. Machi is running a directionally convicted book with defined liquidation floors below each position.
The Position Breakdown — $131M Long Across ETH, BTC, HYPE
Lookonchain flagged the updated position structure on September 19, 2026. The full book breaks down as follows:
| Asset | Size | Notional Value | Liquidation Price |
|---|---|---|---|
| ETH | 32,600 | $85.73M | $2,517 |
| BTC | 495 | $40.26M | $73,501 |
| HYPE | 55,500 | $5.06M | $18.70 |
| Total | — | $131.05M | — |

Ethereum dominates the book at 65.4% of total exposure ($85.73M), with Bitcoin comprising 30.7% ($40.26M) and Hyperliquid’s native token HYPE making up the remaining 3.9% ($5.06M). All three positions are active perpetual longs placed on Hyperliquid.
Why the Liquidation Prices Matter
Liquidation prices define the structural floor beneath which forced selling occurs — and each level here is meaningful. The ETH liquidation at $2,517 sits below key spot support levels. The BTC liquidation at $73,501 is deep enough that a market reversal of significant magnitude would be required to trigger it. The HYPE liquidation at $18.70 similarly reflects a position sized with room for drawdown. These are not reckless entries — they are calibrated levels that suggest Machi is operating with margin discipline, not maximum leverage.
Context — Machi’s Track Record on Hyperliquid
Machi Big Brother has been among the most-tracked large participants on Hyperliquid throughout 2025–2026. His wallet (0x020ca66c30bec2c4fe3861a94e4db4a498a35872) has accumulated a documented history of high-conviction directional bets on the platform. The current $131M long book represents a scale-up from prior disclosed positions, timed alongside a broad market rally.
Machi is not the only large player running structured exposure on Hyperliquid. Earlier this cycle, Abraxas Capital built a $1B short on ETH and BTC via the same platform — representing the opposing directional thesis. The fact that institutional-scale participants are taking concentrated, high-conviction positions in both directions underscores Hyperliquid’s growing role as the venue of choice for large on-chain derivatives exposure.
Abraxas later doubled down on that short at $980M and at another point was holding $472M in shorts while booking $21M in 24-hour PnL. Machi’s $131M long now sits structurally on the other side of that trade type.
Is a $131M Long Book a Reliable Market Signal?
Large on-chain positions are data points — not directional mandates. A $131M long book signals conviction from one well-capitalized participant. It does not confirm that the market will move in that direction. What it does confirm: Machi has sufficient collateral behind these positions to withstand meaningful drawdowns before liquidation levels are reached, meaning forced selling is not imminent at current market prices.
The specific metric to track is whether Machi adds further to these positions or begins reducing size. Real-time position changes are visible on Hypurrscan and will update continuously as the market moves.
Machi Big Brother’s Hyperliquid long book now stands at $131M — 32,600 ETH ($85.73M), 495 BTC ($40.26M), and 55,500 HYPE ($5.06M) — with liquidation floors at $2,517, $73,501, and $18.70 respectively. The position was scaled up as markets rose, per Lookonchain’s on-chain read on September 19, 2026. Watch Hypurrscan wallet 0x020ca66c30bec2c4fe3861a94e4db4a498a35872 for any size changes — additions would reinforce the bull thesis, reductions would be the first signal of conviction fading.
