The record week came in the middle of a memory crash: Sandisk fell 56% from its June high while volume set records, and the exchanges now run perpetuals on the 2x leveraged ETFs of the same names.
Stock and ETF perpetuals traded $211 billion across the crypto exchanges we track in the seven days through July 31, the biggest week on record. Semiconductor names carried $172 billion of it, 82% of the total. Sandisk alone traded $54 billion.
Three companies accounted for $126 billion of the week: Sandisk, SK Hynix, and Micron, the memory makers at the center of the AI build-out.
The volumes are the exchanges' own reporting; nothing in them separates customer demand from an exchange's market-making programs.
The spot stock tokens trade the same names: Sandisk, Micron, SK Hynix, and SOXL were 60% of the $500 million those tokens traded over 24 hours.
Binance's own futures rankings put Sandisk's contract third on the whole exchange, at $7.0 billion in 24 hours. Six of the ten biggest contracts reference stocks or ETFs, and five of those six are chip trades.

The five chip contracts in the top ten traded $17.4 billion together, 1.6 times the biggest Bitcoin contract. Stock and ETF contracts were 41% of everything Binance futures traded.
The week's records printed on the way down. Sandisk closed at $2,335 on June 25. On July 29, the record day, it closed at $1,016, down 56% in five weeks. Micron and SK Hynix fell by about a quarter over the same stretch.
SK Hynix reported its biggest quarter on record into that selling. On July 29 in Seoul it posted revenue up 257% from a year earlier at a 76% operating margin, alongside a capital-spending plan raised to about $31 billion for 2026. The shares closed 10% lower on the day. July 30 ran the other way. Samsung reported quarterly revenue up 130% and described memory supply as tight into 2027. Sandisk rose 26%.
The five biggest stock-perp days on record all landed in that single week, topped by $52 billion on July 29.
Longs on Sandisk's Binance contract paid an annualized 82% on the day the stock made its lows. Then funding flipped negative, and shorts paid through Friday.
The boom has a second story inside it: the leveraged funds built on the same names. Perps on SOXL, a 3x semiconductor ETF, traded $20.3 billion over the week. The newest listings go further, with perpetual contracts on leveraged single-stock ETFs of the memory names themselves. Binance listed a perp on SNXX, Tradr's 2x Sandisk ETF, in early July; it traded $4.6 billion for the week, $1.1 billion of that on Binance on July 31 alone. Perps on Direxion's 2x Micron fund and its 3x South Korea fund trade alongside. The Korea fund's contracts cleared $11 billion in the week. A position in any of them is exchange leverage on a fund that already resets its own leverage every day.
