Understanding Your Quote
Votes Explained
When you buy, you receive "votes" - think of these as shares in your prediction:
Each winning vote is worth $1 when the market resolves
If you buy 100 votes at $0.60, you pay $60 but win $100 if correct
That's a potential 66.7% return!
SolMarkets charges a 1% fee on all trades:
Included in your "You pay" amount
Split: 0.75% to platform, 0.25% to market creator
Creator earnings are tracked and paid out to their balance
Larger trades may move the price:
Small trades: minimal impact
Large trades: you'll see higher average price

New to prediction markets? Start with smaller amounts to learn how pricing works.
Price changes reflect new information. If price moves against you, consider:
Did something change fundamentally?
Is this a buying opportunity?
Markets can be volatile as resolution approaches. Factor in:
How much time until resolution
Likelihood of price-moving news
Don't Overtrade
Fees add up. Make deliberate trades based on real insights, not impulse.
Common Scenarios
"I think YES is undervalued"
Buy YES. If you're right and price rises, you can sell for profit or hold until resolution.
"I want to lock in profit"
Sell your winning position now to secure gains. Don't risk reversal.
Sell to cut losses. It's better to lose 20% than 100%.
Reassess your position. Markets adjust to news - be ready to adapt.
