OKX launched stock perpetuals in February 2026 — TSLA, NVDA, AAPL, META, MSFT, QQQ, SPY, and 10 more tickers. You can now trade US stocks 24/7 with up to 5x leverage, settled in USDT.
But here's the question nobody's answered yet: what does it actually cost to hold these positions overnight?
I use both OKX and Interactive Brokers for real trading. OKX for crypto perpetuals. IBKR for a live USDJPY momentum strategy that runs 24/7 in production. So I pulled the numbers on both to see which platform is cheaper for holding US stock exposure.
The answer isn't as obvious as you'd think.
How OKX Stock Perpetual Funding Rates Work
Stock perpetuals on OKX follow the exact same funding mechanism as crypto perpetuals. The key mechanics:
- Funding is exchanged every 8 hours (00:00, 08:00, 16:00 UTC)
- Longs pay shorts when funding is positive (most of the time for popular stocks)
- Funding rate formula: based on premium index + interest rate component (baseline 0.01% per 8h)
- You only pay if you hold a position at the settlement timestamp — close before settlement, no fee
0.01% × 3 settlements/day × 365 days = 10.95% annualized
But that's just the interest rate floor. The actual funding rate also includes a premium component that fluctuates based on whether longs or shorts dominate. During bullish sentiment on popular stocks like TSLA or NVDA, the funding rate can spike well above 0.01%.
What Does This Look Like on a Real Position?
Let's say you go long $10,000 worth of TSLA stock perpetuals on OKX.
At the baseline 0.01% funding rate:
| Timeframe | Funding Cost |
|---|---|
| Per 8h settlement | $1.00 |
| Per day (3 settlements) | $3.00 |
| Per week | $21.00 |
| Per month (30 days) | $90.00 |
| Per year | $1,095 |
How Interactive Brokers Margin Interest Works
Interactive Brokers charges margin interest as a simple annual percentage rate (APR), calculated daily and billed monthly.As of March 2026, IBKR Pro USD margin rates are:
| Loan Balance | Rate (APR) |
|---|---|
| ≤ $100,000 | 5.14% (BM + 1.5%) |
| $100K–$1M | 4.64% (BM + 1.0%) |
| $1M–$50M | 4.39% (BM + 0.75%) |
Same $10,000 TSLA Position on IBKR
If you buy $10,000 of TSLA on margin at IBKR (assuming 50% initial margin, so $5,000 borrowed):
| Timeframe | Interest Cost |
|---|---|
| Per day | $0.70 |
| Per week | $4.93 |
| Per month | $21.42 |
| Per year | $257 |
On OKX stock perps, you pay funding on the entire notional position regardless of your margin. There's no way to avoid it.
The Real Comparison: Side by Side
Here's the honest cost breakdown for a $10,000 long TSLA position held for 30 days:
| Cost Factor | OKX Stock Perps | IBKR (50% margin) | IBKR (cash, no margin) |
|---|---|---|---|
| Funding / Interest | $90–$150+ | $21.42 | $0 |
| Trading fee (entry) | ~$5 (0.05% taker) | ~$1 (tiered) | ~$1 |
| Trading fee (exit) | ~$5 | ~$1 | ~$1 |
| Dividend rights | ❌ None | ✅ Yes | ✅ Yes |
| Voting rights | ❌ None | ✅ Yes | ✅ Yes |
| Total 30-day cost | $100–$160+ | $23 | $2 |
When OKX Stock Perps Actually Win
Before you close this tab thinking "IBKR always wins" — there are real scenarios where stock perpetuals make more sense:
1. Weekend and After-Hours Trading
IBKR doesn't let you trade most US stocks on Saturday or Sunday. OKX stock perps trade 24/7/365.
If NVDA drops 8% on a Sunday because of a news event, OKX perp traders can react immediately. IBKR users wait until Monday's pre-market. That gap can be worth far more than the funding rate difference.
2. Crypto as Collateral
On OKX, you can use BTC or ETH as margin for stock perps through unified account mode. No need to sell your crypto to get stock exposure.
On IBKR, you need USD (or supported fiat currencies) in your account. Want to trade TSLA? Sell your crypto first, transfer fiat, wait 1-3 days for settlement.
3. No KYC in Some Regions
OKX stock perps are available to crypto-native users without the full brokerage KYC process that IBKR requires (W-8BEN, proof of address, income verification, etc.).
If you're outside the US and want quick stock exposure without a 3-week account approval process, OKX gets you in the door faster.

Here's the thing most people miss: if you open and close a position between funding settlements, you pay zero funding.
Funding settles at 00:00, 08:00, and 16:00 UTC. If you enter a TSLA long at 08:05 UTC and exit at 15:55 UTC, you pay nothing except the trading fee (~0.05% taker each way, so ~0.1% round trip).
On IBKR, margin interest accrues daily regardless. For day trades or swing trades under 8 hours, OKX perps can actually be cheaper.
5. Short Selling Simplicity
Shorting on IBKR requires locating shares to borrow, and you pay a stock borrow fee that varies wildly — hard-to-borrow stocks like GME or TSLA can cost 20%+ annualized.
On OKX, shorting is as simple as clicking "Sell" on the perpetual. No borrowing needed. And if funding is negative (shorts get paid), you actually earn money while holding.
The Hidden Cost Nobody Talks About: Funding Rate Volatility
The biggest risk with OKX stock perps isn't the baseline rate — it's the unpredictability.
IBKR margin interest is stable: 5.14% APR doesn't change day-to-day. You know exactly what you'll pay.
OKX funding rates swing wildly based on market sentiment. During a TSLA rally, I've seen crypto perp funding rates hit 0.1% per 8h — that's 109.5% annualized. Stock perps are new, so we don't have months of data yet, but the mechanism is identical.
If you're planning a multi-week hold, this unpredictability is a genuine risk that's hard to price in advance.
My Recommendation: Use Both (Seriously)
After running the numbers, here's my actual setup:
- Long-term stock exposure (weeks to months): IBKR. The cost advantage is enormous. You get dividends, voting rights, and stable, predictable costs.
- Quick trades and weekend positioning: OKX stock perps. The 24/7 access and crypto collateral flexibility are genuinely useful. Just don't hold through multiple funding windows if you don't have to.
- Short-term momentum plays (<8h): OKX perps, timed between funding settlements. Potentially zero funding cost.

FAQ
How often does OKX charge funding fees on stock perpetuals?
Every 8 hours at 00:00, 08:00, and 16:00 UTC. If you close your position before the next settlement, you don't pay. Stock perps follow the same funding mechanism as crypto perpetuals on OKX.
Is Interactive Brokers margin interest charged daily?
Yes. IBKR accrues interest daily based on your margin loan balance and posts the actual charge monthly (third business day of the following month). The rate is a fixed annual percentage, currently 5.14% for USD balances under $100K on IBKR Pro.
Do you get dividends on OKX stock perpetuals?
No. OKX's terms explicitly state: "Holders of stock perpetuals do not receive dividends, interest, or distributions." You also get no voting rights. For dividend stocks like AAPL or MSFT (which pay quarterly), this is a real cost to factor in.
Can I use Bitcoin as collateral for stock perpetuals on OKX?
Yes, through OKX's unified account mode (multi-currency margin or portfolio margin). You can use BTC, ETH, or other supported assets as collateral without selling them first. This is one of the key advantages over traditional brokerages.
Which is better for day trading US stocks — OKX perps or IBKR?
For pure day trading during US market hours, IBKR is cheaper (lower commissions, no funding risk). But OKX perps have an edge for after-hours and weekend trades when IBKR is closed. If you time trades between OKX funding windows, you can avoid funding fees entirely on intraday moves.
