Trade Kioxia on Hyperliquid

What xyz:KIOXIA tracks

xyz:KIOXIA is a HIP-3 perpetual deployed by trade.xyz that references 1 Kioxia Holdings Corporation ordinary share (TSE: 285A), converted from yen at the live USD/JPY rate. Kioxia manufactures NAND flash-memory and storage products. It is a linear contract margined and settled in USDC: you gain or lose the dollar move times your size, paid in USDC. You don’t own Kioxia shares, can’t vote them and don’t receive dividends.

Hours: Japan day and night sessions

xyz:KIOXIA trades 24/7 on Hyperliquid. trade.xyz takes an external price during a day session, 8:20 AM–4:30 PM Japan time, and a night session, 5:00–11:59 PM (UTC+9), converting the yen price to dollars at the live USD/JPY rate. In US Eastern time (standard time) that covers 6:20 PM–2:30 AM and 3:00–9:59 AM ET. The 30-minute afternoon break, 11:59 PM–8:20 AM Japan time, weekends and Japanese exchange holidays run on internal pricing: a 30-minute moving average that follows Hyperliquid’s own order book, held inside discovery bounds. Because the price is converted, a weaker yen lowers the perp’s dollar price even if the share price in Tokyo is flat. On trade.xyz’s 2026 holiday schedule, the remaining Japanese closures are November 23 (Labor Thanksgiving Day) and December 31.

Leverage, margin and price limits

xyz:KIOXIA allows up to 10x leverage (Hyperliquid API, November 4, 2026) with isolated margin only: each position carries its own margin, so a liquidation here can’t take collateral from your other positions. At 10x, a 10% move against you wipes out your margin, and maintenance margin (5%, half the initial margin at max leverage) liquidates you before that.

Whenever the external feed is off, the mark is held inside a ±10% discovery bound with 2 re-anchors per direction. From the last Tokyo price, it can move at most about +33% / −27% before a hard cap holds until the feed returns. If your liquidation price sits outside the active bound, you can’t be liquidated while that bound is in force; the risk moves to the reopen, when the price can jump past your stop.

Fees. Growth mode is on for this market (Hyperliquid API, November 4, 2026), which cuts HIP-3 fees by 90%: trade.xyz’s tier-0 rate is 0.009% taker / 0.003% maker before staking and referral discounts, against 0.09% / 0.03% at standard HIP-3 rates. Growth mode can be switched off; the live card above shows the current rate.

The 3-for-1 split, and what it did to positions

Kioxia carried out a 3-for-1 stock split with legal effect on October 1, 2026. Hyperliquid can’t rescale open positions for a split, so trade.xyz closed every position instead:

1. At 06:30 UTC on September 28, 2026 the market went reduce-only.
2. At about 06:35 UTC trading halted. Every open position settled at Kioxia’s official TSE closing price, converted at the oracle’s USD/JPY rate, and every order (including stops and take-profits) was cancelled.
3. Around 07:30 UTC the market reopened at a reference price of the settlement price ÷ 3. Traders who wanted exposure had to open new positions.

Settlement carried no trading fee. The lesson applies to every stock perp: a corporate action can close your position for you, at a time you didn’t choose. trade.xyz publishes these on its corporate actions page.

Kioxia makes NAND flash memory and storage. Memory peers: Sandisk, Micron, SK hynix, CXMT and the DRAM ETF.
