OKX vs Bybit Fee Rebate 2026: Bybit 40%, Net Costs

After rebates, Bybit is the cheaper of the two: bound with code FEEOTTER, Bybit pays a 40% rebate, twice a typical 20% code, for a net futures taker of 0.033%. The same code gets you OKX's 20% auto-rebate + exclusive rewards, for a net futures taker of 0.04%. Spot maker is close (Bybit 0.06% against OKX's 0.064%), so if you trade both ways, bind both (fees checked September 2026, rebate rates October 2026).

The short version

• Mostly futures, mostly market orders: Bybit is cheaper. After the rebate, Bybit nets 0.033% taker; OKX at its 20% auto-rebate nets 0.04%.
• Mostly spot limit orders: nearly a tie, Bybit slightly lower. OKX spot maker starts at 0.08% and nets 0.064% after 20%; Bybit's 0.10% nets 0.06% after 40%.
• Bybit with code FEEOTTER pays twice as much: common influencer codes give 20%, Fee Otter gives 40%, which is 200 USDT more on 1,000 USDT of monthly fees.
• Tokenized US stock perps: against Binance's 198-contract reference set, OKX lists 147 and Bybit 171. At 500,000 USDT monthly notional, all taker, the net cost is 200 USDT on OKX and 165 USDT on Bybit.
• Different ways to fix a missing code: OKX has no late-entry window, only the 180-day inactivity recall or its official rebind request. Bybit lets you add a code within 14 days of signup if you have no referrer, and after that offers an official KYC transfer.
• Both use the code FEEOTTER, so you can bind both; you don't have to choose.

Listed fees first: the gap is smaller than you think

A fee rebate is a percentage of the fee, so start with the base. These are the standard-user rates (OKX Regular, Bybit VIP 0):

Fees verified on 2026-09-24 (each exchange's official fee schedule). · Methodology

Three things worth keeping in mind:

• Spot maker is OKX's clearest fee advantage. At 0.08% it is the lowest among the major exchanges that charge a spot maker fee, so pure spot limit-order traders pay a fifth less before any rebate.
• Bybit's futures taker is 2.75 times its maker (0.055 ÷ 0.02); on OKX it is 2.5 times (0.05 ÷ 0.02). The lesson is the same on both: placing limit orders saves more than switching exchanges.
• Futures taker differs by only 0.005 points. At 1,000,000 USDT of monthly taker notional, OKX charges 500 USDT and Bybit 550 USDT, a 50 USDT gap. The rebate is big enough to flip that, as the next sections show.

Rebate rates: OKX 20% auto-rebate + exclusive rewards, Bybit pays 40%

The two calculate the rebate differently, so compare how much of the same fee comes back. These are the rates when you bind through Fee Otter, next to the common influencer referral codes:

On OKX, signing up with the code FEEOTTER gets you the 20%, which OKX charges in full and then refunds straight to your exchange account, and it stays as long as the account sits under FEEOTTER. OKX sets the invitee rebate at 0% to 20%, chosen by the referrer, as its affiliate FAQ explains; plenty of influencer codes are set to 0%. We also run our exclusive OKX rewards and promotions; ask support.

On Bybit, binding through Fee Otter gets you 40%, all of it Fee Otter's extra rebate; Bybit itself has no auto-rebate layer.

In concrete numbers: on 1,000 USDT of monthly fees on Bybit, a common 20% code returns 200 USDT and a 25% code 250 USDT; FEEOTTER returns 400 USDT. That is 200 USDT a month more than a 20% code, or 2,400 USDT a year. OKX is a 20% auto-rebate + exclusive rewards.

Where the two layers come from, and why a rebate can exceed 20%: auto vs extra rebate.

Net cost after the rebate

There is one formula: listed fee × (1 − rebate rate). OKX is always calculated at its 20% auto-rebate. Bybit is calculated at 40%.

Futures (USDT perpetuals)

Bybit's listed taker is 10% higher than OKX's, but bound through Fee Otter it nets below OKX's rate. Where is the break-even? 0.04 ÷ 0.055 ≈ 0.727, so any Bybit rebate above about 27.3% nets below 0.04%. Put the other way: on a common 20% code, Bybit nets 0.055% × 0.8 = 0.044%, more than OKX; with FEEOTTER (40%) it drops to 0.033%.

In money: at 1,000,000 USDT monthly futures notional, all taker, OKX charges 500 USDT, refunds 100 USDT at 20%, and you net 400 USDT. Bybit charges 550 USDT and refunds 220 USDT, for a net 330 USDT. If you are already a VIP on an exchange and want to rebind or sign up elsewhere, contact support and we can help you apply for special trading benefits and exclusive rewards.

Spot

Spot maker is where the two come closest. To bring 0.10% below 0.064%, Bybit needs a rebate above 36% (1 − 0.064 ÷ 0.10), and 40% just clears it. For pure spot traders who use limit orders, OKX's low maker fee almost cancels Bybit's higher rebate; the net gap is 0.004 points. Spot taker is a wider gap: both list 0.10%, so the higher rebate wins and Bybit comes out ahead.

A spot example: 500,000 USDT of monthly spot volume, all maker. OKX charges 400 USDT, refunds 80 USDT, net 320 USDT. Bybit charges 500 USDT and refunds 200 USDT, for a net 300 USDT.

The full method for effective rates is in perpetual fees after rebate. The OKX figures above use OKX's 20% auto-rebate; what actually lands is shown line by line in the rebate dashboard.

Tokenized US stock perps: Bybit lists more, OKX trades more crude

Both list tokenized US stock perpetuals (SPY, NVDA, TSLA, MSTR, crude oil CL and more) at the normal futures rates, so the net costs above apply directly. The figures below come from our tokenized stock perp fee comparison (public exchange APIs, measured 20 September 2026):

Bybit's listed taker is 0.005 points higher, but after the 40% rebate you still pay 35 USDT a month less than on OKX.

Volume matters more than the fee here. Crude oil CL trades more on OKX than on Bybit, while AAPL trades far more on Bybit (13.1M against 1.7M). On a thin market, slippage can cost more than the whole fee difference. Funding rates on names like MSTR and CL also swing hard, so check the current rate and settlement interval before holding a position for long.

Product differences

• Bybit Earn is shared too. Once bound, the yield you earn in Bybit Earn is also shared back with you, which among the major exchanges only Bybit offers. Bybit says the Earn management fee is already reflected in the APR, with no extra charge. Details: Bybit Earn rebate.
• You reconcile in different places. OKX's 20% goes into your OKX account, so you check it there. Bybit is settled in one amount by Fee Otter into your available balance on the rebate site, so you can check it all and request withdrawals in one place.
• Both have a 180-day rule, pointing in opposite directions. An OKX account with no deposit, trade or login for 180 days in a row can be recalled by another affiliate, which is a rebind route. A Bybit affiliate link may be ended after 180 days in a row without a trade, which is a reason not to leave the account idle.
• KYC is required on both. Bybit requires at least Standard identity verification for all products; on OKX an account without KYC is restricted too, and no rebate can be calculated.

Adding a code late and rebinding: very different

If you already have an account and didn't use the code FEEOTTER, the two exchanges offer completely different routes:

OKX: no late entry, but official rebind routes

OKX states that the code has to be entered before the account is created, and it cannot be added or changed afterwards. For existing accounts our rebind guide lists three methods; the first two are official routes:

1. 180-day recall: once the account has had no deposit, trade or login for 180 days in a row, log in through the FEEOTTER link to complete the recall. Don't log in while you wait.
2. Official rebind request: submit the code FEEOTTER on OKX's rebind page and OKX reviews it. The guide suggests leaving the account idle for one to two months first to improve the approval rate.
3. Other methods: non-mainland users closing an account for the first time release their KYC and can sign up again; if none of these work, contact support.

Bybit: add within 14 days, then KYC transfer

Bybit is the friendlier of the two for new users. A main account within 14 days of signup, with no referrer or affiliate code yet, can add the code FEEOTTER itself under Profile → Account → Account Info → Join an Affiliate's Community. Once added it cannot be cancelled or changed (Bybit's official guide). After 14 days, use the official KYC identity transfer:

1. First register a brand-new, unverified account through the FEEOTTER link: the referral code does not move with KYC, so this step must come first.
2. At least 24 hours after the old account finished KYC, go to Profile → Identity Verification → Identity Transfer and move the KYC to the new account.
3. Mind the limits: no second transfer within 180 days of a successful one; withdrawals and fiat are restricted on both accounts for 24 hours; assets, email and phone number do not move.

What rebinding is worth: at 1,000 USDT of monthly fees, moving a Bybit account from a common 20% code to the code FEEOTTER adds 200 USDT a month, or 2,400 USDT a year. Accounts within 14 days of signup can simply add the code; after that, use the KYC transfer.

Which one should you choose?

• Mostly futures, mostly market orders: Bybit. It nets 0.033% taker, below OKX's 0.04%.
• Pure spot with limit orders: close to a tie, with Bybit slightly lower. It nets 0.06% maker against OKX's 0.064%, a 0.004-point gap.
• Mostly spot market orders: Bybit. Both list 0.10%, so the higher rebate nets less (0.06% against 0.08%).
• Tokenized US stocks, including less common names: Bybit covers 171 against OKX's 147; for crude oil CL, OKX has more volume.
• Idle assets you want to put to work: Bybit, since Earn yield is shared too.
• You want an exchange-paid floor: OKX; the 20% lands straight in your exchange account. Ask support about our exclusive rewards and promotions.
• You trade both ways: bind both with FEEOTTER, and the rebates show in one dashboard.

I already have an OKX or Bybit account. Can I still get a fee rebate?

Yes, but the route differs. On Bybit you can add the code FEEOTTER within 14 days of signup if you have no referrer, and use the KYC identity transfer after that. OKX has no late-entry route, so you use the 180-day recall, the official rebind request or the other methods.

Bybit, at 500,000 USDT monthly notional, all taker: 165 USDT net, against 200 USDT on OKX at 20%. Bybit also lists more contracts (171 against 147), though OKX has more crude oil CL volume.
