The calendar is the easy part. For anyone checking the 2027 Masters dates against a possible prediction-market listing, the practical task is to separate the official tournament schedule from Kalshi's contract-specific rules. A tournament date is not automatically a market close, expiration or settlement time.
Primary sources checked: the official Masters Tournament information page, the Masters patron guide, Kalshi's annual series records and the CFTC filing for Kalshi's designated contract market status. The source snapshot for this guide is July 31, 2026.
The official tournament information page identifies the event as the 91st Masters Tournament. It gives the full event week as Monday, April 5 through Sunday, April 11, 2027. Augusta National Golf Club in Augusta, Georgia, is the venue.
The official patron guide confirms both the Augusta National venue and the distinction between practice days on April 5-7 and tournament rounds on April 8-11. That distinction matters when comparing event-calendar language with any future market wording.
The week and round dates are confirmed, but many operational and competitive details are not final. This review did not verify:
General gate and parking times appear in the current patron guide, but those details can change. Readers planning attendance should use the official Masters home page for later field, pairing, ticket-operation and daily-schedule updates rather than treating a static article as the final authority.
Kalshi's public API establishes recurring Masters-related subject areas, not a verified 2027 listing. The KXMASTERS API record is an annual Sports series titled “Masters Tournament.” The separate KXMASTERSCUT API record is an annual Sports series titled “Masters Cut.” Neither annual series record should be described as a live 2027 contract.
The series records linked the PGATOUR contract-terms document and the PGATOURQUALIFY contract-terms document. They also named media organizations as series-level settlement sources. A future contract may use different language or sources, so traders should not assume those documents will control an unlisted 2027 event.
Two dated API checks provide a useful boundary:
Those results are only a timestamped snapshot. They do not prove that no market opened later, and they do not establish eligibility for any reader. Current availability and prices must come from Kalshi's live markets page and the exact event and contract pages.
Masters.com controls the tournament calendar and venue information. It does not define Kalshi settlement. If a relevant market appears, traders should check the exact contract rather than infer terms from the April schedule.
Kalshi's market-rules guidance and market-outcomes guidance explain why the exact contract text matters. The CFTC filing cited above establishes venue-level designated contract market status; it does not verify a specific Masters contract, its availability or its settlement terms.
Readers can also follow the @Kalshi_market channel for general market notes, but the exchange's current event page and exact contract rules remain the controlling sources.
The official 2027 Masters dates are Monday, April 5 through Sunday, April 11, 2027. The Masters Tournament information page identifies this as the 91st edition. Practice rounds occupy the first three days, while competitive tournament rounds run from Thursday through Sunday at Augusta National Golf Club.
The first tournament round is scheduled for Thursday, April 8, 2027. The remaining rounds are Friday, April 9, Saturday, April 10 and Sunday, April 11. Monday through Wednesday are listed as practice-round days. These tournament dates should not be treated as Kalshi close or settlement times.
No live 2027 contract was verified for this guide. On July 31, 2026, the open-event queries for the annual KXMASTERS and KXMASTERSCUT series returned zero events. That snapshot can become outdated, so readers must check Kalshi directly for current availability, exact rules, fees and eligibility.
Traders should verify the exact ticker, market question, participant, close time, expiration, settlement source, outcome definitions, fees and eligibility. They should also review treatment of ties, withdrawals, cancellations, postponements and cut rules. Masters.com supplies tournament information, while the exact Kalshi contract terms control market settlement.
Not financial advice. Prediction-market trading is speculative, and you can lose money. Do your own research.
