Model vs marketWhere the model and the market disagree
Mammoth 85.0% on the model, 63.5¢ on Polymarket. After the spread, the executable edge is +21.0¢ (it's +21.5¢ measured at the mid).
For the Penguins it's the mirror image: 15.0% on the model vs 36.5¢ on the market.
The market had roughly $194K of liquidity when we pulled the book (Oct 19, 2026, 21:51 UTC+8). NHL leans need at least 3.0¢ of edge at the ask.
MatchupInputs
First-listed goalies on ESPN: Arturs Silovs for the Penguins and Karel Vejmelka for the Mammoth. That listing is not a confirmation.
BooksSportsbook check
DraftKings had UTAH -185 with the total at 6.5. Strip the vig and that's 62.3% for the Mammoth.
So the model is 22.7 points higher on the Mammoth than the no-vig book number. When the gap is that big and the books agree with Polymarket, the model is the outlier, and that's worth knowing before reading too much into the edge.
AvailabilityInjuries and availability
ESPN's injury report for the Penguins: Samuel Girard (undisclosed, day-to-day) and Egor Chinakhov (lower body, day-to-day).
On the Mammoth side, ESPN listed Michael Carcone (upper body, out).
VerdictLean, pass, or context?
Formal lean on the Mammoth. The executable edge (+21.0¢) clears the 3.0¢ bar, which is the whole test. It goes on the record win or lose.
To be clear about what kind of lean this is: the sportsbooks sided with Polymarket, so this is the model against the consensus. Set expectations accordingly.
