The 2026-27 NBA season begins on October 20 with an opening-day tripleheader, giving fans three games to follow on the first day of the new campaign.
The start of the season also coincides with growing activity on prediction market platforms that offer basketball-related event contracts.
Platforms Offering NBA Markets
A report published by Sports Betting Dime identifies Kalshi, Novig, Polymarket and OG among the services providing NBA markets, with features varying by platform and state availability.
Kalshi offers contracts covering game outcomes, game-specific events and player performances, according to the report.
Its platform also lets users combine multiple predictions into a single position, including selections involving team victories and individual scoring totals.
Novig focuses exclusively on sports prediction markets, with NBA offerings that include featured game markets and combination selections.
The report states that Novig provides discussion features through a dedicated Discord community and in-app Parlay Huddles.
Polymarket presents basketball markets through an interface that displays order books and charts tracking changes in market prices as game time approaches.
It also supports customized combinations of multiple selections within one position, according to Sports Betting Dime.
OG likewise concentrates on sports event contracts rather than a broader range of prediction markets, and the report lists it among services offering NBA-related trading opportunities during the season's opening period.
Access varies by state, and the report's availability lists show that the four platforms operate across different sets of US jurisdictions, meaning their geographic coverage is not identical.
The opening slate provides the first regular-season matchups for fans following team results and individual player performances.
