LATEST ANALYSIS.
Recent AI-powered prediction market analyses with probability estimates, confidence scoring, and trading signals.
LoL: JD Gaming vs Top Esports (BO5) - LPL Playoffs
This is a live in-progress match where Top Esports currently leads JD Gaming 2-1 in a BO5 series. My estimated probability of JDG winning is 14%, compared to the market's 15.5%, representing only a 1.5 percentage point difference well within analytical uncertainty. The market appears highly efficient given massive volume ($733K+) and sharp line movement from pre-match odds (JDG favored at 1.70) to current live odds (0.155) after TES's dominant Games 2-3 performance. JDG faces a mathematical disadvantage requiring two consecutive wins, and TES's early-game aggression has completely neutralized JDG's scaling strategy in recent games. While JDG's Game 1 stomp (18-3) proves they have a viable win condition, historical base rates show teams down 1-2 in LPL BO5s reverse sweep only 15-20% of the time, dropping to 10-15% when facing unfavorable head-to-head matchups like JDG's 37% historical win rate against TES. The market has efficiently incorporated the live match dynamics, leaving minimal exploitable edge.
LoL: JD Gaming vs Top Esports - Game 4 Winner
The market prices JD Gaming's Game 4 victory at 26% versus my estimated 26%, indicating NO EDGE. The dramatic line movement from pre-series odds (58% favoring JDG) to current Game 4 odds (26% JDG) reflects critical real-time information: as of 12:50 UTC on May 31, Game 4 is described as "currently live or recently completed," and live viewers are clearly observing TES in a dominant position. This aligns with base rates showing teams leading 2-1 in Bo5 series win Game 4 approximately 65-70% of the time, and is reinforced by TES's overwhelming momentum from Games 2-3 (kill advantages of 23-9 and 23-7). The extreme market movement indicates live bettors with real-time game state visibility have incorporated information unavailable to this analysis. With resolution scheduled for 15:00 UTC the same day, there's substantial risk the outcome is already determined but awaiting official publication. The 26% price for JDG appropriately reflects either (a) a small probability of comeback from significant in-game deficit, or (b) the possibility live viewers are misreading game state—both low-probability scenarios.
LoL: Nongshim Red Force vs Dplus KIA (BO3) - LCK Rounds 1-2
This market concerns a League of Legends LCK match between Nongshim Red Force and Dplus KIA scheduled for May 31, 2026 at 6:00 AM ET. CRITICAL: This match has already concluded as of the current date (May 31, 2026). According to the official resolution source (gol.gg), Dplus KIA defeated Nongshim Red Force 2-0, with the match finishing at 10:00 AM UTC. The market is currently pricing Nongshim Red Force at 0.0005 (0.05% probability), which is a post-match price reflecting NS's loss. The true probability that Nongshim Red Force wins this match is 0.0% (0.0) because the match has already been played and they lost. This is not a prediction scenario—it is a documented fact confirmed by multiple sources including the official resolution source, post-match market pricing, and independent reporting. The outcome aligned with pre-match expectations: heavy favorite DK (with 80% H2H win rate, 50% recent form vs NS's 15%, and sharp money consensus) executed the expected 2-0 sweep over struggling NS (on a 3-match losing streak). There is no predictive edge to assess; this is purely post-match documentation of a concluded event.
Will Republicans win the House in 2026?
The market prices Republican House retention at 23.5%, nearly identical to my estimated probability of 22%. As of May 31, 2026—five months before the midterm elections—all available evidence points strongly toward a Democratic takeover: the RealClearPolitics generic ballot average shows Democrats leading by +7.6 points (corroborated by multiple quality polls showing D+5 to D+11), President Trump's approval rating sits at just 39% with 55% disapproving, and the historical midterm penalty has seen the president's party lose House seats in 19 of 22 midterms since 1934. With Republicans defending a narrow majority and Democrats needing only ~3 net seat flips, the fundamentals overwhelmingly favor Democratic control. The 22% probability I assign to GOP retention accounts for residual uncertainty from potential polling error, redistricting advantages in Southern states following recent Supreme Court VRA rulings, and the five-month window for environmental shifts—but these factors provide only modest offset to the strong Democratic headwinds. The market appears efficiently priced and well-calibrated to current political realities.

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.
