OKX and Bybit list almost the same fees (futures taker 0.05% against 0.055%); what really separates them is the fee rebate. Bound through Quant Nova with NOVA888, Bybit pays 30% to 40%, 1.5 to 2 times the 20% that common influencer referral codes give: on 1,000 USDT of monthly fees, a typical 20% code returns 200 USDT and NOVA888 returns 300 to 400 USDT. Under OKX's affiliate policy we publish only 20% (ask support about extra), and signing up with NOVA888 guarantees that 20% comes back to you. After the rebate, futures taker is slightly cheaper on Bybit from Lv.1 (0.0385% against 0.04%), while spot maker is cheaper on OKX (0.064% against 0.07%). There is no overall winner: it depends on whether you mainly trade futures or spot, and if you do both, bind both.
The short version
- Mostly futures, mostly market orders: Bybit is a little cheaper. After the rebate, Bybit Lv.1 nets 0.0385% taker; OKX at the published 20% nets 0.04%. Bybit SVIP nets 0.03575%.
- Mostly spot limit orders: OKX is a little cheaper. OKX spot maker starts at 0.08% and nets 0.064% after 20%. Bybit only gets below that at the invite-only Supernova tier (40%, 0.06%); SVIP still nets 0.065%.
- Bybit with NOVA888 pays 1.5 to 2 times more: common influencer codes give 20%, Quant Nova gives 30% to 40%, which is 100 to 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 (top rate).
- 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.
- The referral code is NOVA888 on both. 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):
| Item | OKX | Bybit | Lower |
|---|---|---|---|
| Spot maker | 0.08% | 0.10% | OKX, by a fifth |
| Spot taker | 0.10% | 0.10% | Tie |
| Futures maker | 0.02% | 0.02% | Tie |
| Futures taker | 0.05% | 0.055% | OKX, by 0.005 points |
Fees verified on 2026-09-24 (each exchange's official fee schedule).
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 guarantees 20%, Bybit pays 30% to 40% by tier
The two calculate the rebate differently, but there is only one yardstick: out of the same fee, how much do you get back? These are the rates when you bind through Quant Nova, next to the common influencer referral codes:
| Item | OKX | Bybit |
|---|---|---|
| Through Quant Nova (NOVA888) | 20% (ask support about extra) | Lv.1 30%, SVIP 35%, Supernova 40% |
| Common influencer codes | 20%, and the referrer may set it to 0% | 20% to 25% |
| Versus a common 20% code | 20% guaranteed to reach you | 1.5 to 2 times |
| Back on 1,000 USDT of monthly fees | 200 USDT (published rate) | 300 to 400 USDT |
| How it is settled | 20% charged then refunded by OKX into your OKX account; extra into the rebate-site balance | Settled in one amount by Quant Nova, by tier, into the rebate-site balance |
On OKX, signing up with NOVA888 gets you the first-layer 20%, which OKX charges in full and then refunds straight to your exchange account, and it does not depend on your tier: it stays as long as the account sits under NOVA888. 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%. Under OKX's affiliate policy we can only publish 20%; ask support about the extra.
On Bybit, the rates are public and rise with your tier: 30% at the no-threshold Lv.1, 35% at SVIP (the highest you can reach by trading) and 40% at the invite-only Supernova tier. Bybit influencer codes commonly give 20% to 25%. For the same trades, NOVA888 pays half as much again as a 20% code from day one, and twice as much at Supernova; against a 25% code it is 1.2 to 1.6 times.
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; NOVA888 returns 300 at Lv.1, 350 at SVIP and 400 USDT at Supernova. That is 100 to 200 USDT a month more than a 20% code, or 1,200 to 2,400 USDT a year. For OKX we publish only 20%; ask support about the extra.
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 the published 20%. Bybit is shown at Lv.1 (30%), SVIP (35%, the highest you can reach by trading) and Supernova (40%, invite-only).
Futures (USDT perpetuals)
| Tier | OKX net taker | Bybit net taker | OKX net maker | Bybit net maker |
|---|---|---|---|---|
| Lv.1 | 0.05% × 0.8 = 0.04% | 0.055% × 0.7 = 0.0385% | 0.02% × 0.8 = 0.016% | 0.02% × 0.7 = 0.014% |
| SVIP | 0.04% | 0.055% × 0.65 = 0.03575% | 0.016% | 0.02% × 0.65 = 0.013% |
| Top (Supernova) | 0.04% | 0.055% × 0.6 = 0.033% | 0.016% | 0.02% × 0.6 = 0.012% |
Bybit's listed taker is 10% higher than OKX's, but bound to NOVA888 it nets below OKX's published rate from Lv.1. 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; only with NOVA888's Lv.1 (30%) does it drop to 0.0385%.
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; Lv.1 refunds 165 USDT for a net 385 USDT, and SVIP refunds 192.5 USDT for a net 357.5 USDT.
Spot
| Tier | OKX net maker | Bybit net maker | OKX net taker | Bybit net taker |
|---|---|---|---|---|
| Lv.1 | 0.08% × 0.8 = 0.064% | 0.10% × 0.7 = 0.07% | 0.10% × 0.8 = 0.08% | 0.10% × 0.7 = 0.07% |
| SVIP | 0.064% | 0.10% × 0.65 = 0.065% | 0.08% | 0.065% |
| Top (Supernova) | 0.064% | 0.10% × 0.6 = 0.06% | 0.08% | 0.06% |
Spot maker is where OKX wins. To bring 0.10% below 0.064%, Bybit needs a rebate above 36% (1 − 0.064 ÷ 0.10). SVIP at 35% falls just short; only the invite-only Supernova tier at 40% clears it. For pure spot traders who use limit orders, OKX's low maker fee beats Bybit's higher rebate. Spot taker goes the other way: 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; Lv.1 refunds 150 USDT for a net 350 USDT, and SVIP refunds 175 USDT for a net 325 USDT.
The full method for effective rates is in perpetual fees after rebate. The OKX figures above use only the published 20%; 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):
| Item | OKX | Bybit |
|---|---|---|
| Coverage of Binance's 198-contract set | 147 | 171 |
| Futures taker | 0.05% | 0.055% |
| CL (crude oil) 24h volume | 57.8M | 42.8M |
| MSTR 24h volume | 20.9M | 22.2M |
| AAPL 24h volume | 1.7M | 13.1M |
| 500,000 USDT monthly, all taker: fees | 250 USDT | 275 USDT |
| Rebate (OKX 20% / Bybit up to 40%) | 50 USDT | 110 USDT |
| Monthly net cost | 200 USDT | 165 USDT |
Even at Bybit Lv.1 (30%), the same 275 USDT in fees returns 82.5 USDT, for a net 192.5 USDT, still below OKX's 200 USDT.
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 and the extra into the rebate-site balance, so you check both. Bybit is settled in one amount by Quant Nova, by tier, into the rebate-site balance, so you can check and withdraw it all 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 NOVA888, the two exchanges offer completely different routes:
| Item | OKX | Bybit |
|---|---|---|
| Add a code after signup | No public late-entry route | Within 14 days, main account with no referrer |
| Official rebind route | 180-day inactivity recall; official rebind request (reviewed by OKX) | KYC identity transfer to a new account |
| Other methods | Non-mainland users close the account to release KYC and sign up again; a family member's identity; contact support | Open a new account with another unused ID document |
| Can the binding change later? | No | No |
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 five methods; the first two are official routes:
- 180-day recall: once the account has had no deposit, trade or login for 180 days in a row, log in through the NOVA888 link to complete the recall. Don't log in while you wait.
- Official rebind request: submit NOVA888 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.
- Other methods: non-mainland users closing an account for the first time release their KYC and can sign up again; or register a new account under a family member's identity; 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 NOVA888 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:
- First register a brand-new, unverified account through the NOVA888 link: the referral code does not move with KYC, so this step must come first.
- 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.
- 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 NOVA888 adds 100 to 200 USDT a month (Lv.1 to Supernova), or 1,200 to 2,400 USDT a year. Accounts within 14 days of signup can simply add the code; after that, use the KYC transfer.
