Power-rating comparison
Packers–Buccaneers is a coin flip on our numbers
There is almost nothing between these two on our numbers. The Buccaneers rate -0.5 (18th of 32), the Packers +2.9 (5th) — 3.4 points apart before home field, inside the error bar of any preseason rating. The split comes out 47%/53%, and this rates as the 3rd-closest game of the 16 in Week 4. 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 Buccaneers at 8.3 wins (favored in 7 of 17) and the Packers at 9.7 (favored in 13) — 1.4 wins apart across the year. By win probability this is the 9th-hardest game on the Buccaneers' schedule and the 5th-hardest on the Packers'.
The sharpest unit gap in the game runs one way: the Packers offense grades +3.2 (5th of 32) against a Buccaneers defense at -1.1 (20th) — 4.3 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Buccaneers offense (+0.5, 18th) meets the Packers defense (-0.5, 15th), a 1.0-point gap.
On the calendar, the Packers are on 10 days and the Buccaneers are on 7 days. The Buccaneers are 3 games into a home stand. None of that is in the model line — our rating model prices teams and home field, nothing else — so rest and travel are yours to weigh on top of the number, not inside it.
Recent history, for context only: 11 regular-season meetings since 2002, 6-5 in the Buccaneers' favour, plus 2 playoff games. They last met in 2023: Buccaneers won 34-20 in December. Over their last 4 meetings the Buccaneers are 2-2. It is not an input to the line — rosters turn over faster than series records do.
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 Packers at 53% 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-26OCT04GBTB is not listed, and a model number is not a market number. Because the model is close to even here — 47% / 53% — the tradable window is narrow: Buccaneers at 42c or below, Packers at 48c 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.

Packers vs Buccaneers — frequently asked
Who is favored in Packers vs Buccaneers in Week 4?
Our power-rating model favors the Packers by 1 points, a 53% win probability over the Buccaneers. The Buccaneers rate 18th of 32 (-0.5) and the Packers 5th (+2.9); Kalshi has not listed KXNFLGAME-26OCT04GBTB yet, so the model line is the only number on the board.
Why does the model call this a toss-up?
Because the Buccaneers (-0.5, 18th) and Packers (+2.9, 5th) are only 3.4 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 47%/53%. In games like this the model is not the deciding input — the contract price is.
