LATEST ANALYSIS.
Recent AI-powered prediction market analyses with probability estimates, confidence scoring, and trading signals.
LoL: Cupid Esports vs Disguised - Game 1 Winner
The market prices Cupid Esports' chances of winning Game 1 against Disguised at an incredibly low 0.0005 (0.05%), virtually guaranteeing a loss. My estimated true probability is significantly higher, around 0.2 (20%). This substantial deviation is primarily driven by the extremely long resolution date of October 2026. Over a two-year period, team rosters, player performance, and the game's meta are highly volatile and unpredictable, making it unreasonable to assign such a near-zero probability to any team's win. While Cupid Esports might be an underdog, the market seems to be overconfident in a future outcome that is fraught with uncertainty, suggesting the YES outcome is heavily underpriced.
UFC Fight Night: Melissa Gatto vs. Ernesta Kareckaite
My estimated probability for Melissa Gatto to win is 0.50, aligning very closely with the current market price of 0.505. This estimate is primarily driven by the market's perception of a highly even matchup, as evidenced by the price and high volume, combined with the absence of specific fighter data (records, recent performance, stylistic advantages) that would allow for a more informed deviation. Given the inherent unpredictability of MMA and the lack of specific differentiating information, it's challenging to find a clear edge against the collective wisdom reflected in the market.
Will Ethereum reach $2,700 October 5-11?
My estimated probability for Ethereum reaching $2,700 between October 5-11, 2026, is 5%, which is notably higher than the market's current price of 2.85%. While the long timeframe and precise date window introduce substantial uncertainty, the inherent volatility of the cryptocurrency market and the potential for future bull runs suggest that a 2.85% chance is too low. Ethereum has demonstrated significant growth potential in the past, and a price point of $2,700 is certainly achievable within the next two years, making the current market price an undervaluation for this specific, albeit low, probability event.
Bitcoin above $82,000 on October 11, 2026
My estimated probability for Bitcoin to be above $82,000 on October 11, 2026, is 0.65, which is considerably lower than the current market price of 0.945. While factors such as the upcoming halving cycle in 2024 and potential continued institutional adoption suggest an upward trajectory, the extreme volatility of Bitcoin and the long resolution timeframe introduce substantial uncertainty. A 94.5% probability for a specific price target over two years out seems overly optimistic, underestimating the significant risks of market downturns, unforeseen regulatory changes, or other black swan events that could prevent Bitcoin from reaching or sustaining that level.

FAQ.
Common questions about prediction market trading, our API, and how rekko.ai works.
What is prediction market trading?
Prediction market trading involves buying and selling contracts on the outcomes of real-world events: elections, economic data, sports, weather, and more. Platforms like Kalshi (CFTC-regulated), Polymarket (crypto-native), Robinhood, and Coinbase offer yes/no contracts priced between $0 and $1. If you buy a YES contract at $0.65 and the event happens, you receive $1.00, a 54% return. rekko.ai provides the intelligence layer that helps traders identify mispriced contracts and act before the edge disappears.
How do prediction market bots use the rekko.ai API?
Trading bots call rekko.ai's REST API to get structured signals (BUY, SELL, or NO_TRADE) with confidence scores, position sizing, and execution guidance. A typical bot flow: poll the LISTING tier for market data, request STRATEGY-tier signals for actionable trades, and use DEEP-tier arbitrage scanning to find cross-platform price gaps. The API returns machine-readable JSON, so bots can parse and execute without human intervention.
What prediction market platforms does rekko.ai support?
rekko.ai currently connects to Kalshi, Polymarket, Robinhood, and Coinbase. Cross-platform arbitrage detection runs continuously across all platforms, alerting you when the same event is priced differently on different platforms. PredictIt integration is planned for Q4 2026.
How does the prediction market API pricing work?
rekko.ai uses transparent, per-call pricing across four tiers: LISTING ($0.01/call) for raw market data, INSIGHT ($0.10/call) for AI-generated analysis and screening, STRATEGY ($2.00/call) for trading signals with position sizing, and DEEP ($5.00/call) for cross-platform arbitrage and correlation analysis. Start with 100 free LISTING calls and 10 free INSIGHT calls, or upgrade to Pro ($49/mo) for volume discounts.
Can I build a prediction market trading bot with rekko.ai?
Yes. Sign up for a free API key, then use the 27 REST + MCP endpoints to power your bot. The STRATEGY tier returns execution-ready signals (BUY/SELL/NO_TRADE) with Kelly-criterion position sizing and confidence scores. Pair that with the LISTING tier for real-time market data and the DEEP tier for arbitrage opportunities. The API is also available on RapidAPI if you prefer managed billing.
How does rekko.ai detect prediction market arbitrage?
rekko.ai continuously monitors the same events across Kalshi, Polymarket, Robinhood, and Coinbase. When the price of an equivalent contract diverges beyond a configurable threshold (default 2%), the DEEP tier flags it as an arbitrage opportunity with the exact spread, suggested position sizes, and estimated profit after fees. Webhook subscriptions can push alerts to your bot in real time.
Is prediction market trading legal?
Kalshi is regulated by the CFTC (Commodity Futures Trading Commission) and is legal for US residents. Polymarket operates on crypto rails and is available internationally. Robinhood offers event contracts through its existing brokerage platform. Regulatory status varies by jurisdiction, so check your local laws. rekko.ai provides market intelligence and educational content, not financial advice.
