On-chain data show that the high-profile trader known as Machi Big Brother turned $152,000 into $12.72 million in just three days on the decentralized exchange Hyperliquid, as a fresh surge in the crypto market put the platform's leveraged perpetuals back in the limelight. Perpetual futures are derivative contracts that let traders take leveraged exposure to an asset's price without holding the underlying coin, with positions backed by margin rather than the full value of the trade.

Hyperliquid already controls a huge portion of trade leverage. The platform held a perpetual futures volume of $12.19 billion on August 22 within 24 hours, almost 30% of the $40.79 billion volume traded by all perpetual decentralized exchanges that day. Because those positions are visible on-chain rather than on a private exchange ledger, analytics services can reconstruct large accounts' activity in real time. In other words, when the trader handling Machi's account reports $12 million in profits, the interest is not just on that single wallet, but on how much risk traders are willing to tolerate and where that risk is located.

The bet: about $103 million in longs on $12.9 million

Data from the on-chain analytics platform HypurrScan reveals the figures behind the news. Machi's portfolio held around $12.9 million in total, consisting almost exclusively of USDC, but carried about $103 million of open trades: $52.4 million in Bitcoin, $44.9 million in Ether, and $6.1 million in Hyperliquid HYPE tokens — the platform's native asset — all in long positions. The account was entirely net long, with a margin ratio of 14.41%. In practical terms, that is roughly $8 of open positions for every $1 of equity in the account.

Ether has contributed to the gain. The price of ETH surged by almost 30% over the last seven days, while its 24-hour futures open interest went on to hit $33.18 billion. With that level of exposure, a solid move in the right direction can quickly result in eight-figure gains. The danger is that leverage works just as fast in reverse. Galaxy Research associate Zack Pokorny cautioned in an August 17 report:

"It's important to note that the entirety of the futures open interest figure does not constitute an absolute amount of leverage."

Nearly 500 liquidations and a Bored Ape fire sale

This latest run by Machi comes in the wake of a prolonged liquidation history. According to Lookonchain, the trader has faced liquidation nearly 500 times. In June, the account was liquidated on seven occasions in a time span of ten hours while making repeated forays into ETH longs.

Falling ETH and PUMP prices previously left Machi's positions at $21.77 million in September 2025, forcing him to top up $4.72 million in USDC to avert liquidation, as Cryptopolitan reported on June 30. Arkham data revealed he had lost a total of $80.43 million since September 2025, including five liquidations on a single January day. To finance the trades, Machi sold several NFTs from his Bored Ape Yacht Club collection, a collection that had previously held 182 NFTs. Set against that record, this week's three-day gain of just over $12.5 million recovers only a fraction of the documented drawdown.

According to Lookonchain's comment on this week's reversal, Machi "doesn't need to sell his Bored Apes to keep his longs going anymore." Machi himself described his strategy in four words on August 20: "I'm longing my longs."

Why the liquidation math is unforgiving

Hyperliquid's liquidation process shows how and why fortunes can turn so fast. According to the platform's documentation, liquidation starts as soon as account equity drops below the maintenance margin, which is set to be 50% of the initial margin required when the asset is leveraged to its fullest. Maximum leverage can be as low as 3x or as high as 40x, and the maintenance level is set at 1.25% to 16.7% of the position value, depending on the instrument. The 1.25% floor applies to the instruments that allow the highest leverage, while the 16.7% ceiling accompanies the most conservative 3x tier.

When it comes to closing positions, all orders are executed using market orders. With regard to positions that exceed 100,000 USDC, the liquidation takes place in 20% increments, each one separated by a 30-second pause. That makes the process transparent, but not forgiving. On roughly $103 million of long exposure, even a relatively modest adverse move can start the liquidation chain. That is why a trader who has been liquidated hundreds of times can still find himself up more than $12 million just days later.
