Predict.fun Invite Code 050AO: Where to Enter It and How to Confirm It Worked

The Predict.fun invite code is 050AO. It applies a flat 10% discount to your trading fees, it is entered during signup, and it cannot be added to an account that already exists.

That last point is why this guide focuses on the mechanics rather than the offer. The discount itself is simple. What actually goes wrong is people missing the field, mistyping the code, or completing registration assuming they can sort it out later. All three are avoidable, and all three are permanent once the account is created.

The discount applies to taker fees, meaning orders that cross the spread and fill immediately. Maker orders, meaning limit orders that rest on the book until someone fills them, carry no fee on Predict.fun at all, so there is nothing for the discount to reduce there.

Before anything else, look closely at the code: 050AO.

The first character is the digit zero. The last character is the letter O. They are adjacent in the string and they are not the same character, and depending on the font you are reading this in, they may look nearly identical.

Written out unambiguously: zero, five, zero, letter A, letter O.

This is by some distance the most common reason an invite code fails to apply. People transcribe it by eye, substitute one for the other, and the platform rejects it or silently accepts nothing. If you are typing manually, type it slowly. If you are copying, copy the whole string rather than retyping what you think you see.

The safest route is not to type it at all. Opening the signup page with the code already attached carries it in the URL, which eliminates transcription entirely.

Predict.fun can be reached three different ways, and the invite code field sits in a slightly different place on each.

Web with a Web3 wallet. This is the standard route. Connect your wallet, then work through account creation. You will be asked to create a display name, and the invite code field appears as part of that setup flow rather than on the wallet connection screen itself. Enter 050AO there before proceeding.

Binance app. Since the integration shipped in April 2026, Predict.fun markets can be browsed and traded inside the Binance mobile app, with gas sponsored on that path. Account setup happens through the in-app flow, and the invite field appears during it. Because this route is optimised for speed, it is the easiest of the three to click straight past.

Trust Wallet. Available since March 2026, with the wallet not custodying your assets at any point. Same principle: the code field is part of the account setup sequence, not something offered afterwards.

On all three, the field is optional. Optional fields are the ones people skip, which is the entire reason this article exists.

Do not assume. Check.

In your settings. Once the account exists, the fee discount status is visible in your account settings. If a discount is active, it will say so. If nothing is shown, nothing is applied.

Against your first fill. This is the definitive test. Take a small position and look at the fee charged. Predict.fun's taker fee is calculated as 2% × min(price, 1 − price) per share, so a 100-share taker fill on a market trading at 50 cents costs $1.00 without a discount and $0.90 with one. On a 20-cent market, 100 shares costs $0.40 undiscounted and $0.36 discounted.

If your first fill matches the undiscounted column, the code did not attach.

Do this on your first trade rather than your fiftieth. Establishing the position on day one takes two minutes. Working out three months later why your fees look like everyone else's, and discovering it cannot be fixed, is the alternative.

Referral attribution on Predict.fun is written when the account is created. It is not stored as an editable preference, so there is no settings toggle exposing it and no support workflow that attaches one retroactively.

This is not a policy someone can make an exception to. It is how referral tracking works structurally across essentially every platform that runs one.

The practical consequence is narrow and absolute: the signup flow is the only opportunity. Everything else about your account can be changed later. Your deposit size, the markets you trade, your order types, your wallet balance. The code cannot.

Everything in the right column works perfectly well. That is precisely the trap: an account without a code shows no error, no warning, and no missing feature. It just costs a tenth more on every taker fill, indefinitely, and there is no moment at which the platform tells you.

Ten percent off a fee is worth ten percent of the fees you were going to pay, which means its value scales entirely with how you trade.

If you take positions frequently in markets priced between roughly 30 and 70 cents, you are paying at or near the top of Predict.fun's fee curve on every fill, and the discount is doing real work. A trader putting $10,000 through 50-cent markets is buying 20,000 shares and paying $200 in taker fees without the code, $180 with it, on that round of activity alone.

If you trade longshots at 5 or 95 cents, the fee is already close to zero and a tenth of close to zero is closer to zero. Still free, still worth having, but it will not change anything.

If you exclusively rest limit orders, you pay no fees whatsoever and the discount has nothing to apply to. This is worth stating plainly because it is easy to enter a code and assume it is saving you money when your order type has already saved you all of it.

The correct order of priorities on this platform is order type first, invite code second. Making rather than taking is a 100% fee reduction. The code is a further 10% on whatever taking you still do. Both are worth having and they stack, but they are not the same size.

Steps five and six are the ones people skip and the ones that actually matter. Step one is the only one that cannot be repeated.

It is not a deposit bonus. No funds are credited for using it.

It does not reduce maker fees, since there are none.

It does not change your yield on deposited collateral, which is a function of the DeFi strategies the platform routes into rather than of how you registered.

It does not alter market prices, odds, payouts or resolution in any way.

It does not stack with other codes into a larger discount. The platform's referral discount is a flat 10%, so codes advertising 20% or more, particularly ones bundled with large cash bonus claims, are worth treating with real scepticism.

It does not apply to an existing account.

What is the Predict.fun invite code? The code is 050AO. It gives a flat 10% discount on trading fees, taking the taker base rate from 2% to 1.8%.

How do I write the code correctly? Zero, five, zero, letter A, letter O. The first character is a digit and the last is a letter, which is the most common transcription error.

Where do I enter it? In the invite code field during account setup, on whichever path you use. The direct link fills it in automatically.

Can I add an invite code after signing up? No. Attribution is set when the account is created and cannot be changed by you or by support.

How do I know it worked? Check the fee discount status in your account settings, then verify against your first taker fill. A 100-share fill at 50 cents should cost $0.90 rather than $1.00.

Is there a cost to using it? No. It reduces your fees and changes nothing else.

Does it apply to maker orders? There are no maker fees on Predict.fun, so the discount applies only to taker fills.

How much are Predict.fun's taker fees? 2% × min(price, 1 − price) per share, which peaks at 50 cents and falls toward zero at the price extremes. With a code, the base rate is 1.8%.

Why does the fee change with share price? The formula ties fee to market uncertainty. Coin-flip markets sit at the top of the curve, near-settled markets at the bottom.

Does the discount expire? It is applied to fees rather than being a time-limited promotion. Terms remain subject to the platform's prevailing conditions.

Can I use the code from the Binance app or Trust Wallet? Yes. The invite field appears in the account setup flow on those paths as well.

What do I deposit? USDT on BNB Chain is the direct route. USDC and other supported networks work with a conversion step.

Can I get my own invite code? Yes, once you have deposited and traded a small amount, an invite code becomes available in your account.

Are codes offering a bigger discount real? The platform's referral discount is a flat 10%. Claims substantially above that, especially alongside large bonus promises, do not match the published structure.

Predict.fun invite code 050AO takes your taker fee base rate from 2% to 1.8%, permanently, on every fill you ever make. It costs nothing, it changes nothing else about the account, and it is written at signup or not at all.

The two things worth getting right are the ones that go wrong most often. Read the code carefully, since the leading zero and the trailing letter O are easy to swap. And verify the discount is live on your first trade rather than assuming, because verification takes two minutes and the alternative is not fixable.

If you are signing up now, use the direct link so the code is attached automatically, confirm the discount status in your settings, and check your first fill against the fee figures above.

Risk warning: Prediction market trading is speculative and positions can lose their entire value, settling at either one dollar or zero. Smart contract, oracle resolution and DeFi yield risks apply, and regional availability is determined by the platform. Fee structures and referral terms are set by Predict.fun and may change.
