Leverkusen visit the WWK Arena on 12 September 2026 (15:30 CEST). As the unbeaten Bundesliga champion in 2023/24 and current EL participant, Leverkusen is structurally far above Augsburg, which typically battles in the lower mid-table. No Polymarket data; based on historical performance, implied win probability is approximately 72%.
Aggregated bookmaker odds make Ryan Garcia the clear favorite with moneylines of -333 to -430 (Benn: +275 to +330), implying approximately 77% win probability for Garcia (OddsChecker, Aug 31, 2026). Kalshi market confirms Garcia ~70%, Benn ~30% (Aug 31, 2026). Garcia won several high-profile bouts in 2025/26 and is considered technically superior. Benn has improved significantly but lacks top international experience. Own calibration: 70% (Kalshi anchor), as both sources are closely aligned.
As top seed, Zverev is projected to face Alex de Minaur in the quarterfinal (ESPN US Open 2026 Men's Bracket, 1 Sep 2026). With proven Grand Slam depth (2020 US Open finalist, AO winner 2024) and a structurally favourable bracket section, he is a clear favourite to reach the semis. Bookmaker odds imply approximately 60% probability. Alcaraz (vs. Shelton) and Djokovic (vs. Medvedev) are in the opposing bracket half — no direct collision before the SF.
Sabalenka is the clear outright favourite at US Open 2026 Women's Singles with implied tournament win probability of ~35–38% per aggregated bookmaker odds (Yahoo Sports/Covers). Swiatek reaching the final and Gauff reaching the semi-final are already open predictions – a Sabalenka win is fully consistent with a Swiatek vs Sabalenka final. Sabalenka has won three Grand Slams since 2023 with exceptional hard-court form.
Jannik Sinner, reigning ATP World No. 1 and multiple Grand Slam champion (Australian Open 2025, 2026), is among the top US Open 2026 favorites. Historically, top-3 seeds at Grand Slams reach the semifinal in ~38–44% of cases. Existing open forecasts account for two SF spots (Alcaraz winning the title, Zverev reaching SF); Sinner's draw half represents a second open slot. Aggregate bookmaker odds imply a ~40–45% SF probability for Sinner — consistent with historical base rates for top Grand Slam seeds. Risks: injury, difficult draw, or a strong unseeded contender.
Bookmaker odds imply approximately 74-76% for Garcia after vig removal; the Robinhood prediction market shows 70% for Garcia / 30% for Benn (as of late August 2026). Garcia won the WBC Welterweight title in February 2026 with a victory over Mario Barrios. Benn defeated Regis Prograis by unanimous decision (April 2026) but is considered an underdog without a world ranking title. Additionally: home market advantage (Las Vegas, US audience) and Garcia's fighting style (explosiveness, high early KO rate) favor the champion. Calibrated value 72% is slightly below bookmaker anchors (74-76%) and close to prediction market consensus (70%), to account for uncertain Benn power performance. Sporting result of two public professional athletes — suitable as public prediction.
Carlos Alcaraz (originally seed No. 1) was eliminated in Round 2 by Jaime Faria (Portugal) (Wikipedia/ATP Tour, September 2, 2026), leaving Sinner as the clear top favorite. Kalshi prices Sinner's outright win at ~22–26%, implying a final-reach probability of ~38–50% (typically 1.5–2× the outright win odds). An existing Cassandra prediction already anchors his semifinal progression; this prediction extends it to the final. Risk: Zverev or Fritz could block the path in the semifinals.
After Stage 9, Enric Mas leads GC by +1:18 over Roglič. Open platform predictions give Roglič stages 12, 14, and 18 (32.5km ITT) – Roglič likely holds the red jersey entering Stage 20. Stage 20 is the queen stage (5,000m climbing, HC Collado del Alguacil) – the last genuine GC day before Granada's flat finale. For Mas to reclaim overall leadership (projected overall winner), he must attack on Stage 20. No prediction market available. Felix Gall (3rd at +1:39 after Stage 9) is an alternative stage-winner scenario.
Alcaraz is the de facto title favourite after Jannik Sinner's withdrawal (knee injury, ESPN). Kalshi rates his win probability at ~27%, DraftKings at +250 (~28.6%), SI.com at +195 (~33.9%). Implied semifinal probability derived from the win market: ~65–68%. Alcaraz won his first two matches dominantly (6-4, 6-4, 6-4 in R2 vs. Safiullin, Sky Sports). This prediction does not contradict the open Zverev win prediction – both can be in opposite semifinal halves.
The 49ers and Rams open the 2026/27 NFL season at the MCG, Melbourne (International Series). The 49ers hold a structural roster edge. The neutral venue eliminates home-field advantage (Rams are the designated home team). Bookmaker odds imply ~57% for San Francisco in this NFC West rivalry matchup.
Jessica Pegula is seeded #3 and placed in the bottom half opposite defending champion Aryna Sabalenka (#1). The projected quarterfinal is Pegula vs. Karolina Muchova (#7), a favourable draw. Pegula is among the strongest US Open performers in recent years and benefits from home crowd support. Her outright odds stand at +1000–+1100 (DraftKings/CBS Sports; implied tournament win probability ~8–9%). The probability of reaching the semi-final is considerably higher, as it only requires winning the quarterfinal against Muchova. Sabalenka winning the final (open prediction) is fully compatible with a Pegula SF appearance. Gauff and Andreeva are in separate quarters and do not compete against Pegula in the QF.
Gauff won rounds 1 and 2 convincingly (incl. 6-3, 6-4 vs. Sonmez) and faces Paula Badosa in round 3 today. A separate open prediction already targets Gauff reaching the quarterfinal (~Sep 8/9); the semifinal requires one further win. The draw is unusually open: Sinner (WD), Djokovic (R1 out vs. Navone, historic first-round loss). Rybakina (No. 2), Pegula (No. 3), and Swiatek (No. 8) also compete for the semis; Pegula-SF and Gauff-SF are not mutually exclusive. Betting market odds imply ~38-42% probability of a Gauff SF appearance.
Polymarket prices Alcaraz at 43% to win the tournament outright, implying ~63% to reach the SF. Sinner (No. 1) and Draper both withdrew injured, opening the draw significantly. Alcaraz won R1 over Safiullin in straights and is projected to face Shelton in the QF, with Zverev on the opposite half. A potential Alcaraz SF appearance is fully consistent with the existing open prediction 'Zverev wins the tournament' (they would meet only in the final). Calibrated at 63% from the Polymarket winner market.
Iga Swiatek holds WTA ranking No. 1 or No. 2 and is one of the most consistent Grand Slam semifinalists of the past four years. Polymarket prices her at ~15% to win the title. SF probability is significantly higher: Swiatek reached the semifinal or better in approximately 55% of Grand Slam starts since 2022. A Swiatek SF is compatible with predicted Sabalenka win (open prediction, Polymarket 28%) and Gauff QF (open prediction). Critical factor: bracket draw — a Sabalenka–Swiatek QF would eliminate Swiatek.
Elena Rybakina (Wimbledon champion 2022) is seeded #3 at the 2026 US Open (main draw from 30 Aug). Aryna Sabalenka (#1 seed) is predicted to win the title and Iga Swiatek (#2 seed) is predicted to reach the semi-final — both covered by open predictions. Rybakina can reach the SF from a different quarter of the draw without creating any logical conflict: four SF slots, three taken by top-3 seeds is historically the norm. Historical SF probability for WTA top-3 seeds at the US Open 2018–2025: ~57–60% (WTA/Tennis Abstract). No specific Polymarket market found.
After Jannik Sinner's withdrawal on 21 August 2026 (knee), Zverev is the second-highest favourite on Polymarket with ~24.5% win probability behind Alcaraz (~36%). Reaching the semi-final typically implies 2–2.5× the win probability, i.e. ~50–55%. Zverev is an established hard-court finalist (US Open 2020). The open draw half following Sinner's absence eases the path. Polymarket prices Zverev to win the tournament at ~24.5%.
Iga Swiatek enters the 2026 US Open on a nine-match winning streak: she won the National Bank Open Montreal (WTA 1000) and defeated Elena Rybakina en route to the Western & Southern Open semi-finals (Cincinnati, August 22, 2026). Kalshi and Covers.com rank Swiatek as the second-best favourite behind Sabalenka (Sabalenka win probability: ~26–30%). For a top player in this form, semi-final probability (top 4 from 32 draw positions) is ~50–55%. This prediction does not contradict the open Cassandra prediction 'Sabalenka wins the title' — both are consistent (Swiatek loses to Sabalenka in the SF). Also consistent with open prediction 'Rybakina reaches SF' — draw-half separation is possible. Risk: Swiatek's historically variable hard-court form post-clay season could surprise downside.
Gauff is seeded 4th (WTA ranking No. 4, August 24, 2026) and just won the 2026 Cincinnati Open (6-2, 6-4 vs Pegula – her first title of 2026). Her 31-12 season record shows strong form. She is the 2023 US Open champion and reached the SF or further in 2 of the last 3 years (winner 2023, SF 2024). Bookmaker odds imply ~14% win probability (+600 BetMGM), from which ~48% SF probability is derived. Main rivals: Sabalenka (favourite, 11/4), Swiatek (6/1), Rybakina (3rd seed).
Pegula (No. 3) leads the second quarter. Her projected quarterfinal against Karolína Muchová (No. 7) is regarded as manageable. Her section also contains Svitolina (No. 9), Cirstea (No. 16) and Navarro (No. 26) — none of the opponents on the route to the semi-final are considered insurmountable. As a US home favourite in New York with proven hard-court strength, bookmaker odds imply ~35–40% SF probability. Prediction is consistent with Cassandra forecasts: Sabalenka wins the tournament, Andreeva reaches the semi-final in the other half.
Yaroslava Mahuchikh is the world's dominant high jumper: Olympic gold at Paris 2024 with a world record (2.10 m) and gold at the 2026 World Athletics Indoor Championships in Toruń (2.01 m, ahead of Angelina Topić SRB and Nicola Olyslagers AUS). As defending champion and current world No. 1, she is the clear favourite. The Ultimate Championship invited only the global elite (Olympic and world champions plus top Diamond League qualifiers). The main rival is Olyslagers (AUS). With no specific prediction market odds available, historical dominance supports an independent calibration of approximately 60–65%.
