Bybit Launches Perp Options to Enable Round-the-Clock US Equity Trading

SpaceX and Nvidia go live first, with Tesla, QQQ, SOXL, and Micron lined up next. The pitch is that a single USDT-funded account can now run options, perps, and spot with portfolio margin offsetting. I want to know whether the order book will actually have depth when it matters.

What the Contract Actually Is

European-style, cash-settled, USDT-denominated. Contract multiplier of one — meaning fractional lots and no $25,000 / 100-share floor that defines TradFi equity options. At launch, you'll get naked longs and shorts, spreads, straddles, combos, plus API access, demo trading, and trial funds. Portfolio margin is wired in from day one, with Perp Options positions cross-offset against related perpetual and spot holdings.

The structural play is straightforward: take Bybit's existing TradFi perp liquidity — which already carries volume on synthetic US equities — and bolt an options surface on top. According to the head of Bybit's option business Mike Xue, the narrative is that traders don't separate crypto from traditional markets anymore and want a single account across both. Fine pitch on the hours. The harder question is what happens when size hits the book.

What I'll Be Probing at Launch

Order book depth on SpaceX and Nvidia perps. This is where the whole product lives or dies. Thin liquidity on the underlying perpetuals means the options surface is decorative — wide spreads, bad fills, and a mark that drifts every time someone pushes size. I'll be testing the book with mid-size clips in the first session.

Portfolio margin offsetting in practice. UTA integration is clean as a marketing bullet. Real question: what haircut regime does Bybit apply to a long perp + short put combination? If the offsets look generous on the spec sheet and brutal inside the liquidation engine, the elegant account structure is lipstick on a liquidation cascade waiting to happen.

Settlement layering. European-style cash-settle removes the early-assignment headache — the one TradFi convention worth importing. Good. But USDT settlement stacks the underlying perp's funding-rate drift on top of Bybit's own settlement risk on the cash leg. Two layers of exposure, not one.

Counterparty baseline. This is still Bybit. No product innovation changes who sits on the other side of your trade. I want proof of reserves refreshed through launch week, and I want to see the liquidation engine perform under a fast tape — not a quiet one.

The UTA Race Is Already On

KuCoin is making the same move from the financing side. Per coverage this week, KuCoin wired its Institutional Interest-Free Lending Program into its Unified Trading Account, dropped the entry threshold for new API clients to 10 million USDT in 30-day volume (down from 30 million), and kept 0% interest for the first two months on borrowing up to 3 million USDT across USDT, USDC, BTC, and ETH.

Same thesis, different end of the stack. Bybit is selling you the trading surface; KuCoin is selling you the funding. For serious capital, the question isn't which slogan reads cleaner — it's which venue combines tight options spreads, a stable liquidation engine, and honest portfolio margin into one account.

Bybit just put the first piece on the table. I'm not impressed yet. I'm watching the book.
