Power-rating comparison
Seahawks–Eagles is a coin flip on our numbers
There is almost nothing between these two on our numbers. The Eagles rate +2.5 (7th of 32), the Seahawks +5.2 (3rd) — 2.7 points apart before home field, inside the error bar of any preseason rating. The split comes out 49%/51%, and this rates as the 1st-closest game of the 16 in Week 15. When the model has no opinion worth holding, the price has to supply the edge.
Zoom out to the full season and the model projects the Eagles at 9.7 wins (favored in 11 of 17) and the Seahawks at 10.8 (favored in 16) — 1.2 wins apart across the year. By win probability this is the 6th-hardest game on the Eagles' schedule and the 2nd-hardest on the Seahawks'.
The defense wins the headline matchup here: the Seahawks grade +1.8 on that side of the ball (4th of 32) against a Eagles offense at +0.5 (17th) — 1.2 points the wrong way for the offense. Going the other direction, the Seahawks offense (+2.3, 7th) meets the Eagles defense (+1.8, 5th), a 0.5-point gap. Special teams adds to it: the Seahawks grade +1.2, 2nd in the league, against +0.2 (24th) on the other side — close to a point of hidden margin.
Scheduling note: this is a Saturday game — one of 2 that day — so it sits outside the main Sunday slate.
One team has owned this series: the Seahawks are 9-2 in 11 regular-season meetings since 2002. They have also met 1 time in the playoffs. They last met in 2023: Seahawks won 20-17 in December. Over their last 4 meetings the Eagles are 0-4. Worth saying plainly — the model does not know any of that. It reads 2026 ratings and nothing else, so a lopsided series is a story, not a number on this page.
Calibration check, because a near-even number is the easiest kind to overtrust: across 3266 walk-forward games (2013-2024) the model gave a side 50-55% in 870 of them, and those sides won 52%. The Seahawks at 51% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.
No price exists for this game yet; KXNFLGAME-26DEC19SEAPHI is not listed, and a model number is not a market number. Because the model is close to even here — 49% / 51% — the tradable window is narrow: Eagles at 44c or below, Seahawks at 46c or below, and a pass on everything between. On near-coin-flips the opening price usually lands inside that window, which is why most games like this end up as no-position. Week 1's KXNFLGAME contracts opened in May 2026 and the rest of the slate lists as the season gets closer; this page picks up the price automatically when it does.

Seahawks vs Eagles — frequently asked
Who is favored in Seahawks vs Eagles in Week 15?
Our power-rating model favors the Seahawks by 0 points, a 51% win probability over the Eagles. The Eagles rate 7th of 32 (+2.5) and the Seahawks 3rd (+5.2); Kalshi has not listed KXNFLGAME-26DEC19SEAPHI yet, so the model line is the only number on the board.
Why does the model call this a toss-up?
Because the Eagles (+2.5, 7th) and Seahawks (+5.2, 3rd) are only 2.7 rating points apart. The 2.5-point home-field adjustment is larger than the gap between the teams, so home field is effectively the entire margin and the split lands at 49%/51%. In games like this the model is not the deciding input — the contract price is.
