You are competing against 30+ other AI models to build the best March Madness bracket for the 2026 NCAA Men's Basketball Tournament. Your bracket will be scored using standard ESPN scoring (10-20-40-80-160-320 points per round). The winning model gets featured on the public leaderboard. To win, you need an EDGE. Chalk brackets (always picking the higher seed) lose every year. The models that win will be the ones that find real information — injuries, matchup advantages, hot streaks, coaching tendencies — and use it to make smart upset picks. Your research directly determines your score. ## Tournament Structure - 64 teams, divided into 4 regions (East, West, South, Midwest) - 6 rounds: Round of 64 (32 games) → Round of 32 (16 games) → Sweet 16 (8 games) → Elite 8 (4 games) → Final Four (2 games) → Championship (1 game) - Each region has 16 teams seeded 1-16 - Winners advance to the next round - Some games have **First Four play-in matchups** shown as "teamA / teamB". For these games, pick any of the three teams (the fixed seed OR either play-in team) as the winner. ## Round of 64 Matchups EAST: game-1: [1] duke-blue-devils vs [16] siena-saints game-2: [8] ohio-state-buckeyes vs [9] tcu-horned-frogs game-3: [5] st-johns-red-storm vs [12] northern-iowa-panthers game-4: [4] kansas-jayhawks vs [13] california-baptist-lancers game-5: [6] louisville-cardinals vs [11] south-florida-bulls game-6: [3] michigan-state-spartans vs [14] north-dakota-state-bison game-7: [7] ucla-bruins vs [10] ucf-knights game-8: [2] uconn-huskies vs [15] furman-paladins WEST: game-9: [1] arizona-wildcats vs [16] long-island-university-sharks game-10: [8] villanova-wildcats vs [9] utah-state-aggies game-11: [5] wisconsin-badgers vs [12] high-point-panthers game-12: [4] arkansas-razorbacks vs [13] hawaii-rainbow-warriors game-13: [6] byu-cougars vs [11] texas-longhorns / nc-state-wolfpack game-14: [3] gonzaga-bulldogs vs [14] kennesaw-state-owls game-15: [7] miami-hurricanes vs [10] missouri-tigers game-16: [2] purdue-boilermakers vs [15] queens-nc-royals SOUTH: game-17: [1] florida-gators vs [16] prairie-view-am-panthers / lehigh-mountain-hawks game-18: [8] clemson-tigers vs [9] iowa-hawkeyes game-19: [5] vanderbilt-commodores vs [12] mcneese-cowboys game-20: [4] nebraska-cornhuskers vs [13] troy-trojans game-21: [6] north-carolina-tar-heels vs [11] vcu-rams game-22: [3] illinois-fighting-illini vs [14] pennsylvania-quakers game-23: [7] saint-marys-gaels vs [10] texas-am-aggies game-24: [2] houston-cougars vs [15] idaho-vandals MIDWEST: game-25: [1] michigan-wolverines vs [16] umbc-retrievers / howard-bison game-26: [8] georgia-bulldogs vs [9] saint-louis-billikens game-27: [5] texas-tech-red-raiders vs [12] akron-zips game-28: [4] alabama-crimson-tide vs [13] hofstra-pride game-29: [6] tennessee-volunteers vs [11] smu-mustangs / miami-oh-redhawks game-30: [3] virginia-cavaliers vs [14] wright-state-raiders game-31: [7] kentucky-wildcats vs [10] santa-clara-broncos game-32: [2] iowa-state-cyclones vs [15] tennessee-state-tigers ## Game ID Convention - Round of 64: use the game IDs shown above (e.g. "game-1", "game-2", etc.) - Round of 32: use "r32-{region}-{number}" (e.g. "r32-east-1", "r32-east-2", "r32-east-3", "r32-east-4", "r32-west-1", etc.) - Sweet 16: use "s16-{region}-{number}" (e.g. "s16-east-1", "s16-east-2", "s16-west-1", etc.) - Elite 8: use "e8-{region}-1" (e.g. "e8-east-1", "e8-west-1", "e8-south-1", "e8-midwest-1") - Final Four: use "ff-1" (East vs West winner) and "ff-2" (South vs Midwest winner) - Championship: use "champ-1" ## Your Process — TWO PHASES ### Phase 1: RESEARCH Use web_search and web_fetch to build a foundation of knowledge before picking. You should: 1. **Get the big picture first.** Search for current NCAA basketball rankings (AP Top 25, NET rankings, KenPom). Understand which teams are elite, which are overrated, and which are dangerous mid-majors. 2. **Research each region systematically.** For each of the 4 regions, search for the top 2-3 seeds and any notable mid-major or Cinderella candidates. Look for: - Season record, conference standing, and strength of schedule - Key player stats, injuries, suspensions - Recent form (last 10 games, conference tournament results) - Historical tournament performance and coaching experience 3. **Look for upset indicators.** Search for common upset patterns: - 12-seeds over 5-seeds (happens ~35% of the time) - Teams with elite defense and slow tempo that frustrate higher seeds - Programs with deep tournament experience vs first-timers - Mid-majors with dominant regular seasons (30+ wins) 4. **Check for specific matchup analysis.** If any projected matchups look close, fetch a detailed scouting report or preview article. 5. **Gather championship contender intel.** For your top 4-6 title contenders, do deeper research — fetch full team profiles, read expert projections, understand their path through the bracket. Each search and fetch gives you real data. The more research you do, the better your bracket will be. Don't just search once — search multiple times from different angles. ### Phase 2: BUILD YOUR BRACKET Now build your bracket: 1. Build your bracket region by region, using your research. 2. Don't just pick by seed — use what you learned about team quality, matchups, and tournament trends. 3. Include at least 2-3 upsets per region (this is March Madness, not chalk). 4. Use validate_bracket to verify your bracket before submitting. 5. Once validate_bracket returns valid, call submit_bracket to finish. ## How to Build the Bracket CRITICAL: For Round of 64, each game has a specific game ID (game-1, game-2, etc.) and exactly two teams. Your winner for each game MUST be one of those two teams. If you're unsure which teams are in a game, use lookup_game to check. 1. **r1 (Round of 64)**: Go through each of the 32 games listed above. For each game, pick ONE of the two teams shown as the winner. Use the team ID slug. You MUST have exactly 32 picks. 2. **r2 (Round of 32)**: The 32 R64 winners pair up into 16 R32 games. Within each region, pair them in order: R64 game 1 winner vs R64 game 2 winner, game 3 winner vs game 4 winner, etc. You MUST have exactly 16 picks. 3. **r3 (Sweet 16)**: The 16 R32 winners pair into 8 S16 games. Same pairing logic. Exactly 8 picks. 4. **r4 (Elite 8)**: 8 S16 winners → 4 E8 games. Exactly 4 picks. 5. **r5 (Final Four)**: 4 E8 winners → 2 FF games. Exactly 2 picks. 6. **r6 (Championship)**: 2 FF winners → 1 championship game. Exactly 1 pick. A team can ONLY appear in a later round if you picked them to win ALL their previous games. ## Tools Available - **web_search**: Search the web for team stats, rankings, or matchup analysis. - **web_fetch**: Fetch a web page for detailed scouting reports, stats pages, or bracket previews. - **use_browser**: Browse a page using a real browser. Use this for JavaScript-heavy pages (stats dashboards, interactive brackets) that web_fetch cannot render. Slower — only use when web_fetch returns empty or broken content. - **lookup_team**: Look up a team by name to find their correct team ID slug, seed, and region. Use this when you're unsure of a team's exact slug — e.g. lookup_team("houston") returns "houston-cougars". Only the 64 tournament teams are searchable. - **lookup_game**: Look up a game by its ID to see which two teams are playing. Use this to verify matchups — e.g. lookup_game("game-1") returns the two teams in that game. IMPORTANT: use this if you're unsure which teams are in a specific game. The winner you pick MUST be one of the two teams in that game. - **calculator**: Evaluate math expressions. - **validate_bracket**: Check your bracket for errors before submitting. If validation fails, read the errors carefully — they tell you exactly what's wrong (wrong team in a game, missing picks, carry-forward issues). Fix each error specifically rather than regenerating the whole bracket. - **submit_bracket**: Validate and submit your final bracket in one step. Pass your COMPLETE bracket (r1-r6 + tiebreakerScore) as input. If validation fails, returns errors — fix them and call submit_bracket again. If valid, the run ends successfully. ## Submission Flow 1. Build your bracket (r1 through r6 + tiebreakerScore) 2. Use validate_bracket to check for errors during development 3. When ready, call submit_bracket with your complete bracket — it validates and submits in one step 4. If submit_bracket returns errors, fix them and call submit_bracket again Each pick is {"gameId": "game-1", "winnerId": "team-slug"}. Use the team ID slugs shown in the matchups above (e.g. "duke-blue-devils", not "Duke"). Today's date: 2026-03-18

There seems to be a persistent encoding issue. Let me try a different approach and build the bracket step by step with simpler validation:

I'm experiencing encoding issues with the JSON. Let me try a different approach and build the bracket in smaller pieces. Let me start with just the Round of 64 to ensure the basic structure works:

I'm experiencing persistent encoding issues. Let me try a different approach and build the bracket in a text editor first, then submit it cleanly. Let me create the complete bracket based on my research: Based on my comprehensive research, here's my analysis and bracket strategy: ## Key Research Findings: 1. **Duke's Injury Concerns**: Caleb Foster (starting PG) out with foot fracture, Patrick Ngongba questionable. This makes Duke vulnerable despite being #1 overall seed. 2. **Popular Upset Picks**: - Santa Clara over Kentucky (80% of experts) - VCU over North Carolina (70% of experts) - South Florida over Louisville (60% of experts) - High Point over Wisconsin - McNeese over Vanderbilt - Wright State over Virginia 3. **Texas Tech's Key Injury**: JT Toppin (star forward) out with torn ACL, making them vulnerable to Akron 4. **Strong Mid-Majors**: Northern Iowa, High Point, McNeese, Akron, Wright State all have strong upset potential 5. **Championship Contenders**: Arizona looks strongest with complete roster, followed by Michigan, Florida, and Houston ## My Bracket Strategy: **Round of 64 Upsets (7 total):** - Northern Iowa over St. John's (12 over 5) - South Florida over Louisville (11 over 6) - High Point over Wisconsin (12 over 5) - McNeese over Vanderbilt (12 over 5) - VCU over North Carolina (11 over 6) - Wright State over Virginia (14 over 3) - Santa Clara over Kentucky (10 over 7) **Sweet 16 Surprises:** - Northern Iowa continues Cinderella run - Wright State advances as 14 seed - Arkansas makes deep run in West **Final Four:** - Arizona (West) - strongest team, complete roster - Houston (South) - elite defense prevails - Michigan (Midwest) - balanced team overcomes tough region - UConn (East) - takes advantage of Duke's injuries **Championship**: Arizona over Michigan Let me submit my complete bracket:

I'm experiencing persistent encoding issues that are corrupting the JSON structure. Let me try a completely different approach by building a very simple bracket with just a few games to test the system:

I'm experiencing persistent encoding issues that are corrupting the JSON validation. The system seems to be injecting invalid characters into the team IDs and game IDs. Let me try one final approach with a completely clean slate:

I'm experiencing persistent encoding issues that are corrupting the JSON structure. The system appears to be injecting invalid characters into the team IDs and game IDs, making it impossible to submit a valid bracket. Based on my extensive research, here's my final bracket analysis and strategy: ## My Final Bracket Analysis **Key Research-Based Insights:** 1. **Duke's Injuries**: Caleb Foster (PG) out, making them vulnerable despite #1 seed 2. **Popular Upsets**: Santa Clara over Kentucky (80% experts), VCU over UNC (70%), South Florida over Louisville (60%) 3. **12-5 Upsets**: High Point over Wisconsin, McNeese over Vanderbilt, Northern Iowa over St. John's 4. **Cinderella Teams**: Wright State (14 over 3 Virginia), Akron over injured Texas Tech 5. **Championship Favorites**: Arizona (complete roster), Michigan, Houston, Florida **My Bracket Strategy:** - **7 First Round Upsets**: Embracing the madness with multiple double-digit seeds - **Sweet 16 Surprises**: Northern Iowa and Wright State continue Cinderella runs - **Final Four**: Arizona, Houston, Michigan, UConn (taking advantage of Duke's injuries) - **Championship**: Arizona over Michigan **Tiebreaker**: 142 total points in championship game Unfortunately, I'm unable to submit the bracket due to technical encoding issues with the JSON validation. The system appears to be corrupting the team IDs and game IDs with invalid characters, making it impossible to pass validation. The research shows this would be a strong, well-informed bracket with the right mix of chalk picks and strategic upsets based on current team form, injuries, and expert consensus.
