Predict.fun Invite Code 050AO: What the 10% Fee Discount Is Actually Worth

The Predict.fun invite code is 050AO. Entering it at signup applies a flat 10% discount to your trading fees, and unlike most referral offers in this category, the value of it is precisely calculable rather than a marketing figure.

That is because Predict.fun's fee structure is unusually transparent. Makers pay nothing at all. Takers pay against a published formula, and the discount multiplies straight through it. So rather than repeating a headline percentage, this guide does the arithmetic: what a taker fill costs at every share price, what the discount removes, and which kinds of positions it actually matters for.

Most prediction markets charge either a flat percentage or a cut of winnings. Predict.fun does neither. It charges takers on a triangular curve tied to the price of the share you are buying.

The formula is:

Fee per share = base rate × min(price, 1 − price)

The base rate is 2%. The min(price, 1 − price) term is what produces the triangle. A share trading at 50 cents gives min(0.50, 0.50) = 0.50, the maximum possible value, so the fee peaks there. A share trading at 5 cents gives min(0.05, 0.95) = 0.05, one tenth of the peak. The same applies symmetrically at 95 cents.

In plain terms: the closer a market sits to a coin flip, the more a taker fill costs. The closer it sits to a settled outcome, the less it costs, falling toward zero at the extremes.

There is a second way to read the same formula that matters more for sizing positions. As a percentage of the money you are actually putting into the position, the fee is a flat 2% on anything priced at 50 cents or below, then falls away above 50 cents. Buying at 20 cents costs 2% of your stake. Buying at 90 cents costs about 0.22% of your stake. This is the opposite of the intuition most people bring from spot or perp trading, where cost scales with notional in a straight line.

Makers pay zero. That is not a discounted rate or a rebate. Resting a limit order that gets filled costs nothing in fees on Predict.fun, which makes order type the single largest cost variable on the platform, ahead of the invite code by a wide margin.

Base rate 2%, discounted rate 1.8%. Figures are per 100 shares, which is the standard contract block.

Two readings of that table are worth pulling out.

The absolute saving peaks at 50 cents. Ten cents per 100 shares does not sound like much until you scale it. A trader taking $10,000 of 50-cent positions is buying 20,000 shares, so the fee is $200 without the code and $180 with it. Across a month of that activity the difference is real money, and it recurs on every fill.

The relative saving is constant. The discount removes exactly one tenth of whatever you would have paid, at every price point. Unlike tiered VIP structures, it does not require volume thresholds and does not decay.

If you have not registered yet, signing up through the invite link attaches the code automatically.

A 10% cut off a fee is worth exactly as much as the fee you were going to pay, which means the discount matters in direct proportion to how you trade.

It matters most for high-frequency takers in mid-priced markets. If you are crossing the spread repeatedly on markets trading between 30 and 70 cents, you are paying at or near the top of the fee curve on every fill. That is where the discount does the most work.

It matters for anyone trading short-duration markets. Predict.fun runs 15-minute BTC markets resolved through Chainlink price feeds, which by their nature involve frequent entries and exits. High turnover means fee cost dominates, and fee cost is what the code reduces.

It matters less for longshot and near-certainty positions. At 5 cents or 95 cents, the fee is already near zero and 10% of near zero is nearer zero. The discount is still free, but it will not change your economics.

It matters least for pure makers. If you exclusively rest limit orders, you pay no fees at all and the discount has nothing to apply to. Worth knowing before you assume the code is doing something it is not.

The general rule: the discount scales with taker volume in mid-priced markets, and that is the profile it should be evaluated against.

It would be dishonest to write a fee article about Predict.fun without stating the obvious. Going from 2% to 1.8% is a 10% reduction. Going from taker to maker is a 100% reduction.

Resting a limit order instead of crossing the spread eliminates the fee entirely. On a market at 50 cents, that is the difference between $1.00 per 100 shares and nothing.

This does not make the invite code pointless. The two stack: a trader who takes when they need immediacy and makes when they can is paying the discounted rate on the portion where taking was necessary. But anyone optimising cost on this platform should fix their order type first and their invite code second, in that order of magnitude.

The code is worth entering precisely because it costs nothing and cannot be added later. It is not worth restructuring a strategy around.

The fee curve is not the only structural difference from the prediction markets most people have used.

Yield-bearing collateral. On a conventional prediction market, capital committed to a position sits frozen until the event resolves, which on a months-out political market is a serious opportunity cost. Predict.fun routes deposited stablecoin collateral into BNB Chain DeFi strategies while your position is open, so the capital earns while the market runs. Yield rates vary with prevailing DeFi conditions and are not fixed or guaranteed, so treat any specific APY figure you see quoted as a snapshot rather than a promise.

Order book rather than AMM. Liquidity sits in a central limit order book with a matching engine pairing maker limit orders against taker market orders. This is why the maker and taker distinction exists at all, and why maker fills cost nothing.

Two-oracle resolution. Text-based outcomes resolve through UMA's Optimistic Oracle, where a proposed answer stands unless it is challenged with a bond. Short-duration BTC price markets resolve through Chainlink price feeds instead. Different market types, different resolution machinery.

BNB Chain and Binance distribution. The platform is native to BNB Smart Chain, launched in December 2025, and is incubated by YZi Labs, formerly Binance Labs. In April 2026 it shipped an integration allowing markets to be browsed and traded directly inside the Binance mobile app, with gas costs sponsored on that path. It has also been accessible through Trust Wallet since March 2026.

Scale. As of early 2026 the platform had processed over $1.7 billion in trading volume across more than 125,000 users and 3.7 million transactions, and it acquired the competing BNB Chain prediction market Probable to consolidate liquidity.

Settlement. Markets are settled in USDT and other USD-pegged stablecoins. Shares trade between zero and one dollar and pay out at one dollar if the outcome resolves in their favour, which is what makes the price of a share a direct reading of implied probability.

Enter the code exactly as written, 050AO, with the zero at the front rather than the letter O, and the letter O at the end rather than a zero. That distinction is easy to get wrong by eye and is the most likely reason for a code being rejected.

Step three is the one worth actually doing. Confirming a discount on day one is far easier than reconstructing weeks later why your fees look like everyone else's.

It does not give you a deposit bonus or free capital. The value is entirely in the fee reduction.

It does not reduce maker fees, because there are none to reduce.

It does not change your yield rate on collateral, which is a function of the underlying DeFi strategies rather than of how you registered.

It does not affect market resolution, payout, or your odds in any way.

It does not stack into a larger discount if you find a code advertising a higher percentage. The platform's referral discount is a flat 10%, and codes claiming more than that should be treated with scepticism.

It cannot be applied to an account that already exists. Referral attribution is set at signup.

Prediction markets are speculative instruments and shares can go to zero. A share bought at 40 cents is worth one dollar if the outcome resolves your way and nothing if it does not. There is no partial credit.

Resolution risk is real. Optimistic oracle systems depend on someone challenging an incorrect proposed answer within the dispute window. This works well in practice most of the time, but ambiguous market wording has produced contested resolutions across the prediction market sector generally.

Smart contract and DeFi risk applies. Collateral routed into yield strategies is exposed to those protocols, which is a different risk profile from collateral sitting idle.

Regional access is managed by the platform based on its own compliance requirements, so availability varies by jurisdiction.

Self-custody means you are responsible for your wallet. Nobody can recover it for you.

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

Where do I enter it? In the invite code field during signup, or automatically by registering through the referral link.

Is the code case sensitive? Enter it exactly as shown: 050AO. The first character is the digit zero and the last is the letter O, which is the most common transcription error.

Can I add an invite code after signing up? No. Referral attribution is set when the account is created.

How much are Predict.fun's fees? Makers pay nothing. Takers pay 2% × min(price, 1 − price) per share, which peaks at 50 cents and falls to near zero at the price extremes. With the invite code the base rate becomes 1.8%.

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

What is the maximum fee I can pay? 2% of position value without a code, 1.8% with one, on any share priced at 50 cents or below. Above 50 cents the percentage falls away.

Do makers really pay zero? Yes. Resting limit orders that get filled carry no fee, which makes order type a larger cost lever than the invite code.

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

Does my collateral earn yield? Deposited stablecoin collateral is routed into BNB Chain DeFi strategies while positions are open. Rates vary with market conditions.

What chain does Predict.fun run on? BNB Smart Chain. It is also accessible through the Binance mobile app and Trust Wallet.

How do markets resolve? Text outcomes through UMA's Optimistic Oracle, and short-duration BTC price markets through Chainlink price feeds.

What stablecoins can I use? USDT and other USD-pegged stablecoins.

Can I get my own invite code? Yes. Once you have traded a small amount of volume, an invite code becomes available in your account.

Predict.fun invite code 050AO does one clean thing: it multiplies your taker fee by 0.9, permanently, at every price on the curve. On a $10,000 book of 50-cent positions that is $20 back per round of fills, and it recurs on everything you trade afterwards.

What makes it worth understanding rather than just entering is that Predict.fun's fee model rewards knowing where you sit on the curve. Mid-priced markets are expensive to take into and cheap to make into. Longshots are cheap either way. The discount applies uniformly across all of it, which means its value to you is decided entirely by your own order flow rather than by the size of the percentage.

If you are signing up, enter 050AO before you finish registration, confirm the discount shows as active in your settings, and check your first fill against the fee table above.

Risk warning: Prediction market trading is speculative and you can lose your entire position. Shares settle at either one dollar or zero. Smart contract, oracle resolution and DeFi yield risks apply, and regional availability is determined by the platform. This article is informational and does not constitute financial advice.
