Perp options vs. traditional stock options: Key differences

Traditional stock options come with built-in friction: exchange-defined trading hours, 100-share contract multipliers, physical delivery of shares and a broker approval ladder that gates access to advanced strategies. Bybit Perp Options take a different approach. Written on TradFi perpetual contracts, they offer equity and ETF exposure that trades 24/7, settles in Tether (USDT) and supports fractional sizing, all within a single Unified Trading Account (UTA). This article breaks down the key differences across trading hours, settlement, contract sizing, exercise style and strategy access.

Key Takeaways:

• Perp Options trade 24/7, settle in USDT and support fractional lot sizing with a 1x contract multiplier, offering more flexibility in timing, position sizing and collateral management compared with traditional stock options.

• Perp Options use European-style exercise and can only be exercised at expiry, while traditional US stock options are generally American-style and may be exercised before expiry.

• Traders can sell naked options, use multi-leg strategies and access portfolio margin within a single Bybit Unified Trading Account, subject to eligibility and applicable margin requirements.

What are perp options?

Perp Options are options contracts written on Bybit's TradFi perpetual contracts, giving traders exposure to US equities and ETFs including TSLA, NVDA, QQQ and SPCX. The underlying TradFi perps let traders gain exposure to US stocks through perpetual contracts and ETFs such as SPY and QQQ without owning the underlying shares. Perp Options add an options layer on top of these markets. They are European-style, cash-settled in USDT, and carry a contract multiplier of one. Because they sit on top of Bybit's perpetual infrastructure, they inherit the 24/7 availability of the underlying perps.

Perp options vs. traditional stock options: Side-by-side comparison

The table below compares Bybit Perp Options with standard US-listed equity and ETF options. Note that some characteristics (such as exercise style and settlement) differ for US index options, which are outside the scope of this comparison.

What do these differences mean for traders?

The table captures the structural distinctions. This section explains why they matter in practice.

Trade on your schedule, not Wall Street's

Standard US equity options primarily trade during exchange-defined sessions rather than continuously. Major catalysts like earnings reports, central bank decisions and geopolitical developments frequently land outside those windows, leaving options traders unable to respond until the next available session. Perp Options trade 24/7, allowing traders to respond to a weekend macro event or an after-hours earnings release without waiting for the next US options session.

Cboe has introduced limited extended-hours sessions for select equity options (7:30–9:25AM ET and 4:00–4:15PM ET outside regular trading hours), and this access is expanding. Even so, coverage remains partial and instrument-specific. Perp Options carry no such restriction.

No early exercise surprises

American-style options can be exercised by the holder at any point before expiry. For option sellers, this creates the possibility of early assignment: an unexpected obligation to deliver or receive shares before the trade has run its course. European-style options can only be exercised at expiry, which removes this variable entirely.

For traders running short calls, short puts or multi-leg spreads, European-style exercise means position outcomes are governed by expiry pricing rather than the holder's discretion at an inconvenient moment. Management becomes more straightforward.

Smaller contract multiplier

A standard US equity options contract covers 100 shares of the underlying, while Bybit Perp Options use a 1x contract multiplier. This allows traders to trade in smaller contract units than with standard stock options.

Strategy access without approval tiers

US brokers are required by FINRA to approve accounts for specific levels of options trading, with firms typically granting access progressively based on the risk and complexity of the strategies involved. Strategies such as uncovered options may therefore require a higher approval level, while portfolio margin carries separate eligibility requirements.

Bybit supports selling naked options and using multi-leg strategies, including spreads, straddles and strangles, within a single UTA. Portfolio margin is available to eligible accounts, subject to applicable requirements. There is no separate broker-style options approval ladder to work through. A trader who already holds a Bybit UTA can access the full strategy set without additional onboarding.

Who should consider perp options over traditional stock options?

Perp Options are likely most relevant for:

• Crypto-native traders who want TradFi equity exposure without opening a separate brokerage account or going through brokerage onboarding

• Active options traders who want broader strategy access without navigating tiered broker approval frameworks

• Macro traders who want to express equity or index views using options with 24/7 availability and USDT settlement

• Existing Bybit TradFi perp users who want to layer options strategies (covered calls, protective puts, spreads) directly on their perp positions within the same UTA alongside their crypto holdings

The bottom line

The core advantages of Perp Options over traditional stock options come down to three things: always-on 24/7 access that lets you respond to market-moving events in real time, European-style exercise that removes early exercise risk from short strategies and a single-account setup that grants access to the full options strategy toolkit without broker approval tiers.

For traders who already operate on Bybit, adding options exposure requires no new account, no new onboarding and no approval ladder. To explore Perp Options, go to TradFi > Perp Options in the Bybit App (version 5.25.0 or later) or web interface to view the available underlyings and start trading.
