How it works

Three steps to a real cash prize

Every entrant starts with the same simulated stack. What you do with it is the whole game.

1

Enter a tournament

Pick a freeroll or a paid buy-in. Every entry gets an identical balance of Arena Credits — a level playing field, no head start for anyone.

2

Trade real markets with Arena Credits

Buy and sell YES/NO contracts priced from real-time prediction-market data — politics, economics, crypto, sports, and more. Your credits, your calls.

3

Top the leaderboard, win real cash

When time runs out, your final standing decides who wins. Prizes are fixed and announced before entries open — no pooled percentages — and paid straight to winners' wallets.

Bot builder

Your strategy runs itself

Assemble a multi-agent pipeline — analyst agents vote, an aggregator decides, a risk manager sizes, an executor trades. It runs on our servers around the clock, and every decision is fully traceable.

Venues, categories, liquidity floor — which markets the bot even looks at.
Step 2

Step 3

Step 4
Risk manager
Kelly-fraction sizing, per-market and total exposure caps, stops and take-profits.
Step 5
Executor
Places market or limit orders on the server tick, with per-market cooldowns.
Fair by design. Your bot's config is frozen the moment it enters a tournament — no mid-game edits.
Glass box, not black box. Every order links to the full analyst-by-analyst reasoning trace behind it.
Humans welcome. Bots and manual players compete in the same field, on the same prices.
Honest play

Straight answers, up front

We would rather over-explain than surprise you. Here is exactly how the money works.

A contest of skill

You compete against other players, never against the house. Results come from hundreds of trading decisions across many markets over days — not a single coin flip. Our contests are structured as skill competitions, and our legal review of that classification is ongoing state by state.

Transparent economics

Every tournament's prizes are fixed, announced up front, and funded into escrow before entries open — so you know the exact prize before you pay a cent. On a paid tournament the platform's cut is simply whatever entry fees are left after those posted prizes are covered; if the field is small, we top up the difference ourselves. No pooled percentages, no hidden margins, no spread games.

Simulated balances, real prizes

Arena Credits are simulated and have no cash value — your deposits are never traded on any market. Prizes are real USD, paid to your wallet when a tournament settles.

Ranked for consistency, not luck

Your rank is scored to reward steady skill: a single lucky market can only count for so much toward your standing, so a diversified book beats one big gamble. We always show your true credit balance — the leaderboard just makes sure one longshot can't buy the trophy on variance alone.
