<a href="https://x.com/Aster_DEX" rel="noopener noreferrer nofollow">@Aster_DEX</a> has crossed $2.3 billion in open interest, according to DefiLlama data tracked on May 11, putting fresh focus on the fast-growing decentralized perpetual exchange and its position in the increasingly competitive on-chain derivatives market.

Alongside its open interest milestone, <a href="https://x.com/search?q=%24ASTER&amp;src=cashtag_click" rel="noopener noreferrer nofollow">$ASTER</a> recorded nearly $52.8 billion in trading volume over the past 30 days, a figure that underscores its growing share of the perpetual DEX landscape. The platform offers MEV-free, one-click trading with up to 1001x leverage and is backed by YZi Labs.
Despite those numbers, the gap between Aster and the market leader remains substantial. <a href="https://x.com/HyperliquidX" rel="noopener noreferrer nofollow">@HyperliquidX</a> currently shows over $9 billion in open interest and approximately $173 billion in 30-day volume, reflecting its dominant position. Hyperliquid captures more than 70% of the perpetual DEX market in open interest, significantly outperforming competitors.
The contrast between the two platforms goes beyond headline figures. Hyperliquid's open interest to volume ratio sits well above the industry average, indicating traders use the platform for longer-term hedging, while Aster's lower ratio implies higher turnover and shorter-term activity.

Aster's rise has not been without scrutiny. DefiLlama previously removed perpetual futures volume data for Aster after detecting trading volumes that mirrored Binance's nearly 1:1 across multiple trading pairs, with the platform's co-founder citing concerns over data integrity. Analysts observed that Aster's trading activity closely mirrored that of Binance's perpetual futures, raising concerns about potential wash trading or non-organic activity. Aster has not issued a detailed public response to those allegations.
The broader perpetual DEX sector has expanded sharply in 2025. By September 2025, daily trading volume across perpetual DEXs hit nearly $97 billion, with monthly turnover reaching close to $1.064 trillion. Perpetual DEXs now command a 26% share of the crypto derivatives market, up from single digits just a year prior.
For now, Aster's open interest milestone marks a notable data point in a sector where scale is growing rapidly, but where the gap between challengers and the established leader remains wide.
