A whale shorting CXMT on Hyperliquid is down $11M with $3.6M in funding costs as Binance prepares to list the China memory stock on August 18.
Changxin Memory Technology is about to get a bigger audience in crypto. Binance will list a CXMT perpetual contract settled in USDT starting August 18, the exchange said. The move follows a wave of equity-style listings on Binance Futures that already added SK Hynix and Samsung Electronics this month.
The Shanghai-listed memory chip stock went public at a $8.6 billion valuation and immediately became a favorite on decentralized trading venues. CXMT has been trading on Bybit and Gate since its debut, and the shares rallied 10% on Monday to a record above $9.
On Hyperliquid, CXMT is now among the top 20 perpetual contracts by open interest at $1.9 million. The action is concentrated in a handful of large positions. One trader shorted CXMT before the IPO and has held the position for a full month. The short is now worth $114.4 million in notional size, with an unrealized loss of over $11 million and $3.6 million in cumulative funding payments, according to data shared by on-chain sleuth VietnamPenguin. The whale initially deposited $32 million on Hyperliquid to open the trade; the remaining margin stands at $22 million before liquidation.
Bulls are winning so far. CXMT has rallied from its IPO price as traders treat it as a pure-play on China's AI memory chip push, a narrative that revived on the Shanghai exchange this month. Most whale-sized longs on Hyperliquid are still sitting on unrealized gains, though the biggest capital remains concentrated in SK Hynix-linked contracts rather than CXMT.
CXMT trading volumes jumped roughly 1,000% on TradeXYZ and up to 1,500% on Bybit in the days after the IPO, data show. The Binance listing could pull in a new wave of retail and institutional flow, given the exchange's larger user base and a capped funding rate of -2% to 2% with 8-hour settlement cycles. Binance will offer its CXMT contract in a physically-backed format, unlike the synthetic perpetuals on decentralized venues.
The contract launches August 18. CXMT shares closed Monday at $9.07 on the Shanghai Stock Exchange, giving the company a market cap above $594 million.
