The 97% Fee Mechanism
Published 6/29/2026, 4:39:13 PM
Hyperliquid Improvement Proposal 3 (HIP-3), launched in October 2025, transitioned the protocol into a modular infrastructure layer allowing third-party builders to deploy perpetual markets. Research indicates that the "97% volume concentration" mentioned in your query is a misinterpretation of the 97% fee allocation to the protocol's Assistance Fund, while the actual concentration risk lies in a single builder, TradeXYZ, controlling over 90% of the open interest (OI) across HIP-3 markets [Source: https://hyperliquid.xyz/blog/q1-2026-recap].
The 97% Fee Mechanism
The 97% figure refers to the protocol's deflationary "flywheel" rather than trading volume concentration. Under HIP-3, trading fees are split 50/50 between the market builder and the protocol. The protocol’s share is directed to the Assistance Fund, which utilizes 97% of those fees for daily HYPE token buybacks [Source: https://www.bankless.com/hyperliquid-hype-tokenomics-hip3].
- Cumulative Impact: As of April 2026, this mechanism has resulted in over $1.1 billion in cumulative buybacks, removing approximately 4.4% of the circulating HYPE supply [Source: https://hyperliquid.xyz/stats/tokenomics].
- Dominance Implication: This aggressive buyback schedule incentivizes the 500,000 HYPE stake required to become a builder, theoretically cementing Hyperliquid's lead by aligning builder success with token value.
Market Concentration: The TradeXYZ Factor
While HIP-3 is permissionless, the ecosystem currently exhibits high concentration in a single entity. TradeXYZ dominates the HIP-3 landscape, specializing in tokenized equities and commodities.

Impact on Market Dominance
HIP-3 has expanded Hyperliquid's dominance beyond native crypto assets into traditional finance (TradFi) markets.
- Asset Diversity: Tokenized assets now represent 23 of the top 30 pairs by open interest on the platform.
- Global Market Share: Hyperliquid commands approximately 32% of the on-chain perpetuals market and over 6% of the total global (CEX + DEX) perpetuals market [Source: https://falconx.io/research/hyperliquid-deep-dive].
- Revenue Leadership: The protocol has become the largest fee-generating entity in DeFi (excluding stablecoins), with $626M in annualized revenue as of Q2 2026.
Strategic Risks
The concentration of 90%+ OI in a single builder like TradeXYZ presents a "key man" risk for the protocol's dominance. If TradeXYZ faces technical or regulatory hurdles, a significant portion of Hyperliquid's non-crypto volume could be lost. Furthermore, HIP-3 markets rely on builder-provided oracles rather than native price feeds, introducing potential manipulation risks that differ from Hyperliquid's core markets [Source: https://hyperliquid.xyz/governance/hip-3].
In summary, HIP-3's fee structure creates a strong deflationary tailwind for the protocol, but its market dominance is currently heavily reliant on the success and stability of a single dominant builder.
