Pittsburgh opens the 2026 season as the home favorite over Atlanta, and the two exchanges pricing the game do not disagree by a single cent. As of September 5, 2026 the Steelers sit at 63c on both Kalshi and Polymarket and the Falcons at 38c on both, on a board carrying roughly $137K in cumulative volume across moneyline, spread, total and prop legs. The quarterback matchup is a 42-year-old Aaron Rodgers against Tua Tagovailoa in his first start for a new team, under two head coaches who were employed elsewhere a year ago. Kickoff is 1:00 PM ET on Sunday, September 13, 2026 at Acrisure Stadium.
Pittsburgh went 10-7 in 2025, won the AFC North, and lost 30-6 to Houston in the Wild Card round on January 12, 2026. Atlanta went 8-9, finished third in the NFC South behind Carolina and Tampa Bay at the same record, and missed the playoffs. The board reads that gap the way you would expect: the Steelers are the home side at 63c and the Falcons are at 38c as of September 5, 2026, and both books agree to the cent. Neither team has played a 2026 regular season snap, so every number on this page is 2025 form plus an offseason of roster turnover.
The Falcons vs Steelers moneyline is the deepest part of the board, about $41.5K on the Pittsburgh side and $26.0K on Atlanta. Kalshi holds nearly all of it: roughly $41.0K of the Steelers-side total against about $443 on Polymarket. The Polymarket leg is a thin echo of the Kalshi book rather than an independent opinion, which is worth knowing before treating the matching prices as two books confirming each other.
The two legs sum to 101, so the board carries about a point of overround, tighter than a retail sportsbook two-way on the same game. There is no cross-platform value spot here. The widest split on any rung the two exchanges both price is 2c, on the over 41.5 total, and the moneyline, the primary spread and the primary total all match exactly.
On movement, be careful what you read into this board. Its per-line snapshot arrays are empty and its own coverage block reports zero captured ticks, so the game page itself has no history to show. The price endpoint does carry a short series: captures running from the evening of September 4 into the early hours of September 5, 2026, roughly six hours. Across that window Pittsburgh held 63c on Polymarket through all 11 captures and Atlanta ranged between 37c and 38c on Kalshi through 13. That is a flat six hours, not a flat week.
ESPN's 2026 depth charts list Aaron Rodgers first for Pittsburgh, ahead of Mason Rudolph, and Tua Tagovailoa first for Atlanta, with Michael Penix Jr. second and carrying a questionable designation dated September 3, 2026. Rodgers, 42, threw for 3,322 yards with 24 touchdowns against 7 interceptions in 16 games in 2025, at a 65.7% completion rate and a 94.8 passer rating. Tagovailoa's 2025 was his last in Miami: 2,660 yards, 20 touchdowns and 15 interceptions in 14 games at a 67.7% completion rate. Penix started nine games for Atlanta in 2025 and threw for 1,982 yards with 9 touchdowns and 3 interceptions, the best touchdown-to-interception ratio of the three.
Polymarket has listed a seven-rung Aaron Rodgers passing yards ladder for this game, from 149.5 up to 349.5. Every rung is unpriced with zero volume as of September 5, 2026, so there is nothing to trade there yet, but the existence of the ladder is the market's own read on who takes Pittsburgh's first snap.
The skill positions cut against the quarterback framing. Atlanta returns Bijan Robinson, who ran for 1,478 yards on 287 carries at 5.2 per attempt with 7 touchdowns in 2025 and added 79 receptions for 820 yards, and Drake London, who put up 68 catches for 919 yards and 7 touchdowns in 12 games. Pittsburgh's DK Metcalf caught 126 passes for 1,239 yards and 11 touchdowns in 2025 and is listed questionable as of August 31, 2026, alongside new arrival Michael Pittman Jr. If both Pittsburgh receivers are limited, the 63c price is leaning on a defense and a home field rather than on the passing game.
The spread ladder brackets the game tightly. Pittsburgh -3.5 is the busiest rung at 48c (48c Kalshi, 48c Polymarket) on roughly $7.5K, and Pittsburgh -2.5 sits at 57.5c (58c Kalshi, 57c Polymarket) on about $6.1K. A -3.5 rung just under 50c with -2.5 near 58c puts the implied line at Pittsburgh by about 3, the standard shape of a modest home favorite. Pittsburgh -6.5 draws 38c on about $6.8K, so the market gives the Steelers roughly a 38% chance of winning by a touchdown.
The total is priced right at 42. Over 42.5 trades at 49c (49c on both books) on about $2.1K, and over 41.5 at 52c (51c Kalshi, 53c Polymarket). That is a low number relative to both teams' 2025 scoring environments. Pittsburgh's games averaged 46.1 combined points last season (397 scored, 387 allowed across 17 games) and Atlanta's averaged 44.4 (353 scored, 401 allowed). The board is pricing this opener two to four points below both, which is consistent with two new coaching staffs, a 42-year-old quarterback and a quarterback making a first start with a new team.
The moneyline resolves to the team that wins the game at Acrisure Stadium in Pittsburgh on Sunday, September 13, 2026, kickoff 1:00 PM ET. The winning side pays $1 per share and the losing side settles at zero. Spread rungs settle on the final margin and total rungs on the combined final score, both after the game is official. Kalshi and Polymarket settle once the game goes final on the scheduled date; a postponement moves settlement to the rescheduled result under each platform's rules.
Season-long context for this opener trades on the Pittsburgh Steelers playoff market and the Atlanta Falcons playoff market, with the Steelers 2026 win total pricing the same roster over a full schedule.

Resolves to the team that wins the Atlanta Falcons at Pittsburgh Steelers game on Sunday, September 13, 2026 at Acrisure Stadium in Pittsburgh, kickoff 1:00 PM ET. The winning team's moneyline contract pays $1 per share and the losing side settles at zero. Spread contracts settle on the final margin of victory and total contracts on the combined final score, in both cases after the game is official including any overtime.

The game trades on Kalshi under the KXNFLGAME-26SEP13ATLPIT event and on Polymarket under its NFL ATL-PIT event. Kalshi holds the large majority of the volume, roughly $41.0K on the Steelers moneyline against about $443 on Polymarket.
Pittsburgh, at 63c on September 5, 2026, an implied win probability near 63%. The Steelers went 10-7 and won the AFC North in 2025 while Atlanta went 8-9 and finished third in the NFC South, and Pittsburgh is the home team.
The market implies Pittsburgh by about 3 points: the -3.5 rung trades at 48c and the -2.5 rung at 57.5c. The total sits right at 42, with over 42.5 at 49c and over 41.5 at 52c as of September 5, 2026.
It resolves when the game goes final at Acrisure Stadium on Sunday, September 13, 2026, kickoff 1:00 PM ET. Watch Michael Penix Jr.'s questionable status and the health of Pittsburgh receivers DK Metcalf and Michael Pittman Jr., the two inputs most likely to move the price before kickoff.
