Why Sandisk’s SNDK Perpetuals Became Crypto’s Biggest Stock-Linked Trade

The comparison with Micron is also revealing, although the available figures are not perfectly synchronized. One report put 24-hour SNDK perpetual volume at nearly eight times Micron-linked volume, with Micron at about $320 million. Earlier venue-level reporting showed Micron open interest above $254 million on Hyperliquid and approximately $175 million on Binance in June, but those numbers should not be treated as an August 17 market-wide comparison.

Open interest also needs careful interpretation. It is the notional value of positions that remain open; it does not show whether traders are collectively bullish or bearish. Long and short positions can expand together, and a large open-interest reading does not mean the same amount of capital was used to buy shares.

Why Sandisk attracted leveraged traders

Strong results made the ticker easy to understand

Sandisk’s fiscal fourth-quarter results supplied a powerful fundamental narrative. The company reported $8.97 billion in revenue, up 51% sequentially, and $6.90 billion in GAAP net income. Management attributed roughly one-third of sequential revenue growth to higher volume and two-thirds to pricing.

The company also reported strong data-center momentum. Its fiscal 2026 results included a substantial increase in data-center revenue, reflecting demand associated with enterprise storage and AI infrastructure.

For leveraged markets, that combination matters. A company exposed to a recognizable theme—AI infrastructure and memory demand—with sharp earnings momentum can become easier to trade than a less familiar industrial or consumer name. Traders do not need to model every part of the business to form a view on the central narrative: AI-related demand is lifting memory pricing, volumes and expectations.

Customer agreements added visibility

Sandisk said it had eight agreements with six customers. Reporting on the company’s outlook said those arrangements were expected to cover about half of fiscal 2027 production and roughly two-thirds of fiscal 2028 output.

Those commitments do not eliminate commodity, execution or valuation risk. They do, however, give traders a more concrete reason to treat the company as a growth and supply-demand story rather than only a momentum ticker. Additional reporting on Sandisk’s fiscal 2028–2030 model described expected revenue growth in the mid-to-high teens and significant contracted revenue under its new business model.

Perpetuals remove the clock from the trade

A stock perpetual is designed to track a reference price without a conventional expiration date. On crypto platforms, it can generally be traded with margin and around the clock, subject to each venue’s rules, funding mechanics and liquidation processes.

That structure creates a different trading experience from owning stock during regular market hours. It lets traders express a view through a crypto account, use leverage and react to news outside the primary equity session. The same features can accelerate both the buildup and unwinding of open interest.

SNDK was part of a much larger market shift

Sandisk’s rise was not an isolated event. Crypto exchanges have been adding perpetual contracts tied to traditional assets, including stocks, metals and oil. Reported open interest in that segment more than doubled from late May to above $2 billion by late July.

Centralized-exchange equity-perpetual activity expanded even faster by one reported measure: monthly volume rose from about $15 billion in April to nearly $250 billion in July, or roughly 17 times. The exact totals depend on which venues and contracts are included, but the direction points to growing demand for leveraged, extended-hours exposure to traditional assets.

SPCX and SKHX fit naturally into that trend. SpaceX offered a high-profile private-company and technology proxy, while SK Hynix and Micron represented the same broader semiconductor and memory theme. SNDK appears to have won the most attention because its fundamental narrative, recent price action and available perpetual-market liquidity reinforced one another.

What institutional participation can—and cannot—prove

Institutional names appear in the surrounding equity-derivatives ecosystem. Jane Street reportedly disclosed a 5% Sandisk stake, while market records identified Susquehanna and Citadel Securities in roles connected with Sandisk options or related leveraged products.

That evidence is consistent with greater professional interest in liquidity, hedging and arbitrage around highly traded equity exposure. It does not prove that every named firm was trading or making markets in SNDK perpetuals on crypto venues. Traditional market participation and crypto-perpetual participation are related, but they are not interchangeable claims.

The expansion of conventional products points to the same underlying demand. In July, CME launched cash-settled single-stock futures on dozens of U.S. equities, including products designed to trade for nearly 24 hours on its Globex platform. Crypto exchanges and regulated derivatives venues are therefore competing, in different ways, to provide extended-hours access to equity risk.

The central caveat: SNDK perpetuals are not Sandisk stock

Buying an SNDK perpetual does not provide Sandisk ownership. The holder does not receive voting rights or dividends; instead, the contract provides synthetic exposure to a reference price.

That distinction changes how the $1.73 billion figure should be read. It is a measure of demand for a derivative instrument across monitored venues, not a measure of institutional ownership, shareholder capital or the company’s market capitalization.

It also creates regulatory and market-structure questions:

• How reliable are the price indexes used to settle contracts across fragmented venues?
• How should platforms manage manipulation, liquidations and extreme funding costs?
• What customer protections apply when an equity-like product trades through crypto infrastructure?
• Which regulator and rulebook should govern a synthetic contract that resembles an equity derivative but lacks shareholder rights?

For now, the SNDK market shows how quickly a recognizable traditional-asset narrative can migrate into crypto derivatives. Its record open interest is both a sign of demand for 24-hour, leveraged equity exposure and a reminder that trading activity in a synthetic contract should not be confused with ownership of the underlying company.
