SKHX (SK Hynix) rose 3.5% over one hour on Hyperliquid on June 30, while SMSN (Samsung Electronics) gained 2.7% over the same period. According to BlockBeats On-chain Detection, monitoring data from Hyperinsight showed SKHX recorded $340 million in intraday trading volume.
The moves followed Goldman Sachs’ latest June DRAM sentiment survey, which raised its expected 2027 HBM price increase for Samsung from 14% to 44%. Separately, South Korea’s May DRAM export value was reported to have risen 370% year over year, setting a new record.
Market participants appeared to interpret the data as signs of sustained AI-driven memory demand, tightening HBM supply and demand, and improving profit expectations for memory makers. Strength in related South Korean sectors also came after the country recently announced a semiconductor investment and industry ecosystem development plan worth about 580 billion won.
Against this backdrop, a whale on Hyperliquid opened the largest intraday position in the SKHX contract, taking a 3x leveraged long of 2,196 SKHX contracts.
