Islanders vs. Senators: Ottawa priced at 61% on Polymarket ahead of tonight's 7:00 PM ET start

Ottawa favored before puck drop

Ottawa is the favorite on Polymarket ahead of the Islanders–Senators NHL game on Oct. 15, 2026, scheduled for 7:00 PM ET. The supplied pricing snapshot puts the Senators at 61 cents, implying a 61% chance of winning, and the Islanders at 40 cents.

The accompanying summary cites about $124,600 in total trading volume. Polymarket’s supplied market page separately reports $125,271, displayed in rounded form as $125.27K, with $116K attributed to the moneyline. Those figures distinguish activity across the matchup’s markets from trading on the outright winner alone.

According to Polymarket, the market opened on Sep. 18, 2026, at 11:30 AM ET and lists Oct. 15, 2026, as its end date. The provided material does not include a price history establishing how Ottawa’s current advantage developed.

Settlement goes beyond regulation

Polymarket’s moneyline settles on the game’s winner, counting overtime and shootouts. For settlement calculations, a shootout gives the winning side one additional goal.

The other listed contracts ask different questions. Ottawa must win by 2 or more goals for the margin market to settle in favor of the Senators; any other result favors the Islanders. Four scoring-total markets require combined goals of at least 5, 6, 7 or 8, respectively, to settle as “Over,” with lower totals settling as “Under.”

According to Polymarket’s rules, a postponement keeps the markets open until the game is finished. Cancellation without a make-up game instead produces a 50-50 settlement.

What it means for prediction markets

• The 61% reading applies to an outright Ottawa win. It does not indicate the probability of a Senators victory by 2 or more goals.
• Volume measures differ. The $125,271 page total covers the matchup’s markets, while the moneyline displays $116K.
• Extra play affects settlement. Overtime and the additional goal assigned after a shootout count toward the final result and scoring totals.
• The scheduled end date is conditional. A postponement extends the market until completion; cancellation without a make-up game triggers 50-50 resolution.
