Why Compare OKX and Interactive Brokers?
If you're a non-US resident wanting to buy US stocks, these two platforms represent the two main approaches:
- OKX: Crypto exchange with stock tokens (derivatives) — the new way
- Interactive Brokers (IBKR): Traditional international broker — the established way
Both serve international investors. Both let you buy US stocks without an SSN. But the costs, features, and experience are very different.
Fee Comparison: The Full Picture
Trading Fees
| Fee Type | OKX Stock Tokens | Interactive Brokers |
|---|---|---|
| Buy $1,000 of Tesla | $0.50 (taker 0.05%) | $1.00 (min commission) |
| Buy $1,000 with 20% rebate | $0.40 | N/A |
| Buy $10,000 of Tesla | $5.00 | $1.00-5.00 |
| Spread | Near zero (order book) | $0.01 bid-ask |
Winner: Roughly tied for small amounts. OKX cheaper for frequent small trades due to referral rebate. IBKR cheaper for large single trades.
Deposit Fees
| Method | OKX | Interactive Brokers |
|---|---|---|
| Local bank (P2P) | 0-2% | Not available |
| Wire transfer | N/A | $0 incoming, $10-50 bank fee |
| Credit card | 1-3% | Not available |
| Crypto transfer | $0.50-2 network fee | Not available |
| Typical cost for $1,000 | $10-20 | $15-50 |
Winner: OKX — far more deposit options and usually cheaper, especially in developing countries where wire transfer fees are high.
Withdrawal Fees
| Method | OKX | Interactive Brokers |
|---|---|---|
| Local bank (P2P) | 0-2% | N/A |
| Wire transfer | N/A | $10 fee + bank charges |
| Crypto | $0.50-2 | N/A |
| Typical cost for $1,000 | $10-20 | $10-35 |
Winner: OKX, especially for countries without cheap wire transfer options.
Other Fees
| Fee | OKX | Interactive Brokers |
|---|---|---|
| Account maintenance | $0 | $0 (removed in 2024) |
| Inactivity fee | $0 | $0 (removed) |
| Funding rate | ~0.01%/8hrs (~0.03%/day) | N/A |
| Currency conversion | Included in P2P rate | 0.002% (very cheap) |
| Dividend | N/A (no dividends) | Received (minus 20% withholding tax) |
Note: OKX's funding rate is a significant ongoing cost for long-term holders. If you hold a position for 1 year, the funding rate alone could cost 10%+. This makes OKX better for short to medium-term trades.

The Hybrid Strategy
Many smart investors use both platforms:
- OKX for short-term trades and small positions
- IBKR for long-term holdings and dividend stocks
This gives you the best of both worlds: OKX's easy access and low entry barrier, plus IBKR's ownership benefits for your core portfolio.
Verdict
There's no single "best" platform. The right choice depends on your situation:
- Trading $100-500, short term? → OKX
- Investing $5,000+, holding for years? → IBKR
- No international bank account? → OKX
- Want dividends and real ownership? → IBKR
- Want to trade on weekends? → OKX
