In crypto, it only takes one bold player to shake an entire market. That is exactly what happened after transferring 70 million USDC to Hyperliquid, when a whale went long on 166 million USD worth of ETH. On-chain trackers picked up a huge inflow of USDC stablecoins to Hyperliquid, a fast-growing decentralized perpetual futures exchange that has become a magnet for high-leverage traders and crypto “whales.”
Shortly after the deposit hit the platform, the wallet associated with the transaction opened a massive ETH long position worth roughly $166 million in notional value. This was not a slow, incremental build; it was a decisive expression of conviction in Ethereum and a high-stakes bet on future price appreciation.
The move comes in the context of growing liquidity and volume on Hyperliquid, where large whales have already made headlines with nine-figure ETH positions and liquidations that triggered tens or hundreds of millions in outflows from the protocol’s liquidity vaults. For example, a previous over-leveraged ETH long of around $270–340 million was liquidated on March 12, 2025, leading to about a $4 million loss for Hyperliquid’s HLP vault and roughly $166 million in net outflows from the platform.
In this article, we will unpack every layer of this story: Hyperliquid’s role in the market, what it means to go long with such size, why whales choose USDC, what retail traders can learn from this kind of aggression, and how to manage risk when volatility spikes.
What Is Hyperliquid and Why Do Whales Use It?
Hyperliquid as a Decentralized Perpetual Futures Exchange
Hyperliquid is a decentralized perpetual futures platform where users can trade crypto assets like ETH, BTC and altcoins with significant leverage, often up to 25x or more on major pairs after recent risk adjustments. Rather than using a centralized order book held by one company, Hyperliquid is built on a decentralized architecture that aims to combine the speed of centralized exchanges with the transparency and self-custody of DeFi.
The platform has grown rapidly, surpassing $1 trillion in cumulative trading volume and capturing a large share of the perpetual futures market. This explosive growth makes it an ideal playground for large traders who want:
Against this backdrop, one more large ETH whale stepping in with 70M USDC and going long on $166M of ETH is far more than a single trade. It is a live case study in:

When a whale moves tens of millions in USDC into Hyperliquid, they are effectively arming themselves with margin ammunition to open large leveraged positions.
The Role of the HLP Vault and Platform Risk
Under the hood, Hyperliquid uses a Hyperliquidity Provider (HLP) vault, which acts as a pooled liquidity backstop for traders. When traders win, they earn from the vault; when traders lose, the vault may profit. However, when a trader’s position is extremely large and becomes under-collateralized, the vault can be hit with losses, especially during forced liquidations.
That is exactly what happened in the March 2025 incident, where a 175,000 ETH long position worth over $270–340 million at 50x leverage was liquidated, causing a $4 million loss to the HLP vault and prompting a $166 million net outflow as depositors rushed to withdraw.
This history matters because every new whale position is not just a personal gamble; it is also a systemic stress test for Hyperliquid’s risk engine and its liquidity providers.
Inside the Trade: 70M USDC In, $166M ETH Long Out
Why Start With 70 Million USDC?
The story begins after transferring 70 million USDC to Hyperliquid. USDC is a fiat-backed stablecoin pegged one-to-one with the US dollar, widely used as margin collateral on both centralized and decentralized derivatives exchanges. By moving such a large amount in one shot, the whale signaled several things:
First, they wanted instant, stable collateral. Funding a huge ETH position directly with ETH introduces price risk even before entering the trade; by using USDC, the whale avoids pre-trade volatility and can size the position precisely.
Second, the deposit itself reflects institutional-scale capital. Very few individual traders can move 70M USDC at once. The size suggests either a sophisticated proprietary desk, a fund, or a highly capitalized individual who is comfortable risking multi-million-dollar swings in PnL.
Third, it shows trust in Hyperliquid’s infrastructure. Even after the earlier liquidation event and outflows, the whale is willing to park 70M USDC on this one platform to execute a specific ETH long strategy. That speaks to Hyperliquid’s perceived execution quality, user experience and risk controls after adjustments like lowering maximum leverage on BTC and ETH from 50x down to 40x and 25x respectively.
Building a $166M ETH Long Position
With 70M USDC ready as margin, the whale then opened an ETH perpetual long with a notional value of around $166 million. This implies significant leverage, even if not as extreme as previous 50x examples.
A long ETH position on Hyperliquid means the trader is betting that the price of Ethereum will rise. Instead of buying ETH spot, they use perpetual futures to control a much larger exposure with less capital. If ETH goes up, their unrealized PnL grows rapidly; if ETH falls, their margin ratio shrinks and liquidation risk accelerates.
While this is less extreme than 50x leverage, it is still a huge directional bet on Ethereum and more than enough to cause large liquidations if the market swings sharply against it.
What This ETH Long Says About Market Sentiment
From Liquidation Fear to Renewed Bullish Conviction
The previous Hyperliquid ETH liquidation spooked traders and led to second-largest daily outflow in the platform’s history, with data showing around $166 million leaving Hyperliquid in a single day. That kind of exodus usually marks a period of fear, distrust and cautious positioning.
So when a whale returns with a massive ETH long, it suggests a few possible interpretations:
One, the trader believes the worst of the panic is over and that forced sellers have already been flushed from the system. After large liquidations, order books can reset, funding rates normalize and new opportunities appear for those willing to step back in.
Two, the whale might be betting on Ethereum-specific catalysts such as ETF flows, scaling upgrades, L2 ecosystem growth, or improved macro conditions that support risk assets. Rising open interest across derivatives platforms and growing ETH futures volume support the idea that leverage is returning to the Ethereum market.
Three, it reflects the growing role of Hyperliquid whales as market makers of sentiment. When a known address builds big long exposure, social media, on-chain analytics dashboards, and whale trackers pick up the signal. That attention can create a reflexive loop where traders watch the whale, align with their bias, and add leverage of their own.
Hyperliquid Whales as “New Market Makers”
Hyperliquid has become a battleground for institutional-level positions, with whales routinely building positions worth tens or hundreds of millions of dollars. These actors are not passive liquidity; they are active directional traders using:
Conclusion
The story of what happened after transferring 70 million USDC to Hyperliquid, when a whale went long on 166 million USD worth of ETH, is more than just click-worthy drama. It is a window into how modern crypto markets function at scale.
On one side, we have Hyperliquid, a high-growth, decentralized perpetual futures exchange whose design attracts large, aggressive traders with a taste for leverage. On the other, we have ETH whales, willing to deploy tens of millions in stablecoins to build massive long positions that can either earn fortunes or trigger cascading liquidations.
FAQs
Why did the whale transfer 70M USDC to Hyperliquid instead of ETH?
The whale likely chose USDC because it is a stable, dollar-pegged asset that simplifies margin management. By funding their account with 70M USDC, they can size a leveraged ETH long position precisely without being exposed to ETH price swings before the trade is even opened. Using USDC also makes it easier to track PnL in dollar terms and potentially shift capital quickly into other positions or assets on Hyperliquid.
