Incumbent Democrat Bill Keating seeks re-election in Massachusetts’s 9th district, which covers Cape Cod, the South Shore, and New Bedford-area communities and carries a Cook Partisan Voting Index of D+6. Keating’s established record, fundraising edge, and the district’s consistent Democratic performance—most recently a 13-point margin in 2024—underpin the 94% trader consensus for a Democratic hold. Republican nominee Tyler MacAllister, a local selectman, faces the structural headwinds typical of GOP candidates in Massachusetts House races, where no Republican has won a seat since 1994. With Democratic and Republican primaries scheduled for September 1 and the general election on November 3, 2026, the market reflects the limited realistic pathways for an upset, such as an unforeseen national Republican surge or a significant Keating-specific development that would need to overcome the district’s partisan baseline and historical turnout patterns.

A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources.
This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
