The 2027 NCAA Division I Men's Basketball Tournament introduces a 76-team field for the first time. Selection Sunday falls on March 14, 2027, with tournament play starting two days later. For readers checking Kalshi's college basketball markets, this guide separates the verified NCAA calendar from the exact contract rules.
Primary sources checked: July 26, 2026. The NCAA's official 2027 tournament schedule (published May 7, 2026) and the NCAA future Final Four sites page provide the calendar dates and venue confirmations. Kalshi's KXMARMAD series API record confirms the existence of a Men's College Basketball Tournament Champion series, and the CFTC trading organization filing documents Kalshi's regulated status.
The NCAA published the complete 2027 tournament calendar on May 7, 2026. Unlike previous years with a four-team play-in round, the 2027 format expands to 76 teams with a 12-game Opening Round. Here is the verified schedule:
Note that the NCAA uses "Opening Round" for the March 16-17 games in 2027. This replaces the older "First Four" terminology. The 12 Opening Round games feed into a 64-team First Round bracket, not the traditional 68-team field.
The 2027 tournament marks the first season with a 76-team field. This expansion affects bracket structure and the number of games before the traditional 64-team rounds begin.
Key format details from the NCAA schedule:
The NCAA future-sites page independently confirms the Opening Round hosts and Final Four venue.
Kalshi operates a CFTC-regulated prediction market platform. The platform's public API identifies KXMARMAD as a Sports series titled "Men's College Basketball Tournament Champion."
On July 26, 2026, a query of the Kalshi API returned the following:
This snapshot establishes that Kalshi has a subject-area connection to college basketball tournament outcomes. It does not prove that any specific market remains open when you read this, that individual team contracts exist, or that prices, liquidity, or fees match any assumptions.
The dated open-events API query reflects status as of July 26, 2026 only. Traders must verify current availability directly on Kalshi's live markets page.
Before trading any tournament market, separate the NCAA calendar from Kalshi contract rules. These are distinct sources with different purposes:
The NCAA schedule tells you when games happen. Kalshi's contract terms tell you how a market settles. These are not interchangeable. A tournament date does not automatically become a contract close time or settlement trigger.
Review Kalshi's market rules guidance and market outcomes documentation to understand how contract terms work. The NCAAB contract terms PDF provides settlement language for college basketball markets, though individual contracts may have specific variations.
This is a static source checklist, not a live market tracker or bracket prediction tool. The following information was not verified and should not be assumed:
The open status of KXMARMAD-27 was checked on July 26, 2026. Market availability changes. Always verify the exact contract on Kalshi before trading.
Before placing any position on a 2027 March Madness market, complete these checks:
The 2027 NCAA Division I Men's Basketball Tournament begins with the Opening Round on Tuesday, March 16, 2027. Selection Sunday, when the bracket is announced, falls on March 14, 2027. The Opening Round games take place in Dayton, Ohio and Wichita, Kansas before the 64-team First Round begins March 18. This schedule comes from the NCAA's official calendar published May 7, 2026, and should be rechecked closer to the event for any changes.
The 2027 Final Four is scheduled for Saturday, April 3, at Ford Field in Detroit, Michigan, and the championship game is scheduled there for Monday, April 5. Both the NCAA tournament schedule and the NCAA future-sites page confirm those dates and the venue. Recheck the live NCAA calendar before the event for any change.
Kalshi's public API identifies a series called KXMARMAD (Men's College Basketball Tournament Champion) and returned an open event titled "Men's 2027 College Basketball Champion" in a July 26, 2026 snapshot. That snapshot does not confirm that any specific market remains open, is available to a particular reader, or has particular prices. Verify current availability and the exact contract rules directly on Kalshi.
The NCAA schedule says the 2027 tournament field has 76 teams. It lists 12 Opening Round games on March 16-17 before the 64-team First Round begins March 18. A 12-game round involves 24 teams, not 12. The official 2027 schedule uses "Opening Round" rather than the older "First Four" label.
