Arthur Hayes Reveals Portfolio Focused on BTC, ETH, ZEC and HYPE

Hyperliquid is a decentralized exchange that began with perpetual contracts, while HYPE offers exposure to growth in the platform’s trading activity and fees. BitMEX co-founder and Maelstrom chief investment officer Arthur Hayes is bullish on HIP-3, which allows third parties to deploy markets, and HIP-4, which introduces event contracts. He believes Hyperliquid could expand into a general-purpose financial contracts platform and challenge Polymarket and Kalshi.

Lookonchain said Hayes bought 26,022 HYPE on April 11, 2026, at an average price of $41.31, for about $1.1 million. That lifted his holdings to 247,334 tokens worth $10.44 million, with an unrealized gain of more than $2.2 million. However, he sold his entire position from June 4 to June 6. When an address linked to him withdrew another 33,979 HYPE worth about $2.09 million on June 8, Hayes denied that he had made the purchase.

Arthur Hayes co-founded crypto derivatives exchange BitMEX and also invests in digital assets through his family office, Maelstrom. Arkham Intelligence's analysis of his wealth allows observers to assess whether the actual holdings of an investor known for high-risk market views align with his public persona.

As of July 20, 2026, Arkham Intelligence estimated Hayes' net worth at about $200 million to $350 million. His identifiable on-chain assets totaled only about $42 million, 64% of which was held in USDC. Most of his remaining wealth came from his BitMEX equity and undisclosed Maelstrom positions, reflecting a relatively conservative on-chain allocation.
