Open interest in storage-related contracts on Hyperliquid diverged over the past day, according to Hyperinsight data cited by BlockBeats on Aug. 3.
Micron (MU) posted a drop of about $39.372 million in open interest, bringing the total down to $173 million. SK Hynix (SKHX) fell by about $64.124 million to $352 million. Together, the two contracts lost about $103 million in open interest, with declines of 18.5% for MU and 15.4% for SKHX.
SanDisk (SNDK), by contrast, expanded. Its open interest rose from about $88.122 million to $120 million, up by $32.114 million, or 36.4%. That made SNDK the only one among the three storage names to record an increase in positions.
Price moves over the same period
In the last 24 hours, SNDK gained about 0.6%, MU rose about 0.3%, and SKHX fell about 1.1%. On that basis, SNDK outperformed MU by about 0.3 percentage points and SKHX by about 1.7 percentage points.
How large addresses adjusted positions
For SNDK, new positioning leaned long. Over the past 24 hours, one address added about $2.515 million in SNDK longs, and Hyperinsight did not detect any single address cutting longs by more than $1 million or opening a new short above that threshold.
For MU, two addresses added a combined $3.428 million in long exposure, while two other addresses reduced longs by $2.587 million, leaving a net long increase of about $841,000. Over the same period, two addresses opened about $2.858 million in new short positions, which left incremental flow tilted to the short side.
For SKHX, there were no new addresses. Existing whales continued to deleverage. Million-dollar addresses cut longs by a net $6.811 million, while short positions were reduced by a net $9.208 million.
Current long-short balance among top addresses
- MU: 14 long addresses and 18 short addresses, with about $46.108 million in long value versus about $66.543 million in short value.
- SKHX: 37 long addresses and 42 short addresses, with about $104 million in longs versus about $136 million in shorts.
- SNDK: 12 long addresses and 10 short addresses, with about $37.441 million in long value, still below about $46.782 million in short value.
