Sportsblock predictions just got cheaper. And your stake is yours.
We started predictions as a side product and a potential sink for MEDALS and it is working well. However we need to tweak the model to move towards the Polymarket model (but just for Sports). Early on one of the captains 
The 10% fee on every market is dead. Long live the 4%.
We just shipped the biggest economic change to Sportsblock's prediction markets since launch. Three things you need to know.
What changed
| Before | After | |
|---|---|---|
| Total fee | 10% of every pool | 4% of the losing pool |
| Where fees come from | Every staker — win or lose | Losers only |
| Where fees go | 100% burned to @null | 2% to market creator / 2% burned |
| Your stake when you win | Reduced by fee | Returned in full + winnings |
Your stake is yours now
This is the big one.
Old way: you staked 100 MEDALS, won, and got 90 back plus winnings. The other 10 went straight to the burn pile. The house took its cut whether you called it right or wrong.
New way: you stake 100 MEDALS, you win, you get 100 MEDALS back. Plus your slice of the losing pool. Principal-protected. Always. No matter what.
The fee comes from the losing side. Winners pay nothing.
Worked example
A 1,000 MEDALS market settles 500 winning pool / 500 losing pool.
| Before | After | |
|---|---|---|
| Fee taken | 100 MEDALS (10% of total) | 20 MEDALS (4% of losing 500) |
| To creator | 0 | 10 MEDALS |
| Burned | 100 MEDALS | 10 MEDALS |
| To winners | 900 split pro-rata → 1.8× | 980 + 500 stake-back → 1.96× |
Same pool. Same outcome. Winners take home more. Losers lose less than they did before — some of their loss now flows to the creator instead of vanishing into the burn pile.
Creators get paid
Markets used to be free to create and paid nothing back. From now on, 2% of every losing pool goes to whoever set the market up.
Set a sharp question. Pull bets on both sides. Take your slice when it resolves. Your sports knowledge is worth real money.
MEDALS still get burned
The supply story stays intact. 2% of every losing pool still goes to @null and never comes back. Slower than before, sure — but more sustainable now that the burn isn't sucking the rewards out of every winner.
Every losing pool tightens the MEDALS float. Forever.
Why we did this
10% felt fair on launch day. It wasn't.
Charging winners on top of paying them was the wrong shape. Predictions are zero-sum already — the only honest place to take a fee is from the side that called it wrong. So that's where it comes from now.
Burning 100% of fees was the wrong shape too. It paid no one. With 2% to creators, the platform finally has a real economy on top of the pool: someone makes the market, someone backs the call, the pool pays them out, MEDALS supply contracts a little, life goes on.
V2 is going live this weekend and we will fully flip from V1 to V2 by next week.
Open the new prediction markets →
Existing legacy markets play out under the old rules until they settle. Every new market created from next week runs on the new fee model. The V1 model will still be running as normal but it will still be on the older fees. The plan is to phase V1 out as soon as the relegation predictions are paid out which will not be long if Spurs beat Chelsea next Monday.
Nothing for you to do. Just stake harder. Win more. Lose less.
Pure sports. Real rewards.
