Mar 19, 2026, 12:07 AMYou 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

## 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. You have NO validator tool — your bracket must be correct on submission. Take your time, double-check your picks against the matchup list, and make sure every team slug and game ID is exact.
5. When done, call submit_bracket with your complete bracket.
## 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. Refer to the matchup list above carefully.
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.
- **calculator**: Evaluate math expressions.
- **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. Call submit_bracket with your complete bracket — it validates and submits in one step
3. 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").

Before the final game of the college basketball season, 67 games will be played, and 67 teams will be eliminated, with one final team left standing on April 6.\n\n[Filling out a bracket](https://www.cbssports.com/college-basketball/news/2026-march-madness-picks-predictions-first-round-games-bracket/) is one of the most entertaining things you can do. Crafting the perfect bracket isn't an exact science, but our CBS Sports experts are here to help you out with picks from the first round to the Final Four.\n\nSomething to consider when filling out your bracket is that since the NCAA Tournament expanded to 64 teams in 1985, No. 1 seeds have accounted for 65 of the 160 Final Four spots, which is about 40.6% of the total participants. Last year, all four No. 1 seeds reached the Final Four for the first time since 2008 and the second time ever. [Florida](https://www.cbssports.com/college-basketball/teams/FLA/florida-gators/) was the last team standing after defeating [Houston](https://www.cbssports.com/college-basketball/teams/HOU/houston-cougars/) in the title game.\n\n**_Share the madness with your friends, family and co-workers with your own [March Madness](https://cbssports.com/college-basketball/ncaa-tournament/) Ⓡ group.
