By accessing or using PredictionArenas ("the Platform"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not use the Platform.
PredictionArenas is a skill-based continuous trading prediction exchange. Players compete to demonstrate superior forecasting ability by accurately predicting the probability of specific outcomes using our Pure Pari-Mutuel (PM) and Central Limit Order Book (CLOB) matching engines. All transactions on the platform utilize a free-to-play proprietary virtual currency known as "Beats" (BTS).
Skill-Based Competition in a 2-Phase Market
PredictionArenas is a skill-based competition platform built on a dual-phase pricing engine. Market events are split into two distinct operational phases:
By using this Platform, you acknowledge that you are acting as an Independent Playerparticipating in a skill game. You are not an employee or contractor of PredictionArenas. You are participating for entertainment and the opportunity to win prizes based on your analytical skill.
Your relationship with PredictionArenas is that of an independent contractor. You are responsible for your own tax obligations and compliance with local laws in your jurisdiction.
Free Starter Credits (Beats)
Upon registration, each new Analyst receives 100 BTS free virtual credits. These virtual credits are strictly for entertainment purposes, automatically credited, and have no expiry. Virtual credits carry no real-world monetary value and cannot be withdrawn as cash.
Phase 1: Trading Structure
To encourage maximum liquidity and dynamic positioning, market trades execute via a routing layer optimized for value:
• Buying/Selling via PM: Pari-Mutuel execution absorbs your virtual transaction directly into the global pool probability structure.
• CLOB Restoring limits: Taker orders swept from the Order Book are subject to an 8-Second execution delay to protect Maker counterparties from high-frequency manipulation.
Phase 2: Zero-Fee Protocol Settlement
Upon market resolution, the Protocol distributes payouts with 0% Terminal Fees.
100% of the Gross Pool is distributed strictly pro-rata to users holding units in the correct winning bucket. If no users hold units in the winning bucket, the pool is refunded entirely.
All "Potential Payout" estimates displayed on the UI automatically calculate Expected Value at exactly 100% conversion value.
You agree NOT to:
Violation of these terms may result in immediate account termination, forfeiture of assets, and a permanent ban from the Platform.
If a match/event is officially cancelled or postponed indefinitely, all active Phase 1 trading is reverted, and all positions are returned to traders at cost.
PredictionArenas offers organized, time-bound competitions ("Arenas") where players pay a fixed USD entry fee to compete for a Guaranteed Prize Pool.
When the tournament concludes, the Guaranteed USD Prize Pool is automatically distributed to the top-ranked analysts based on the pre-defined payout structure (e.g., 1st: 50%, 2nd: 30%, 3rd: 20%).
Split Stakes Logic: In the event of a tie in Total Portfolio Value at the conclusion of the Arena, the platform employs a standard split-stakes algorithm. Tied players will combine the payout percentages of the ranks they occupy, and that sum will be divided equally among them. For example, if two players tie for 1st place in a standard payout structure, they will combine the 1st (50%) and 2nd (30%) place prizes, and each receive 40% of the total prize pool.
PredictionArenas dynamically hosts various tournament formats spanning sports, finance, and culture. These Arenas may be structured around single high-profile events (e.g., Championship Finals) or span a collection of events over a multi-day window (e.g., Weekend Leagues).
The specific rules, underlying markets, and duration limit for each Arena will be clearly defined on the entry page prior to joining. All Arenas adhere to the same underlying mechanics of trading performance and strict bankroll isolation.
// Phase 2 Settlement Payout (Winner Takes All)
Payout_per_Unit = (Gross_Pool × 1.00) / Winning_Units
Live Market Warning: All Arena data (including Spot Price and Estimated Payouts) updates in real-time.
Due to network latency or rapid market activity, the values displayed on your screen may differ slightly from the system state at the moment your forecast is processed ("Slippage"). Your transaction will always be processed based on the confirmed system state at the exact micro-second of execution on the backend ledger.
