It felt like they were invincible for a while, didn't it? If you were watching the NFL this past year, the Kansas City Chiefs seemed to have this weird, supernatural ability to win games they had no business winning. They’d be down, Patrick Mahomes would look human for three quarters, and then—boom—a blocked field goal or a last-minute scramble would keep the streak alive. But even the best dynasties have bad days at the office. If you're wondering who did Kansas City lose to in 2024, the list is actually a lot shorter than most people expected when the season kicked off, but the losses they did take were massive.
The Chiefs finished the 2024 regular season with a stellar 15-2 record. Honestly, that's insane. Most teams would sell their souls for a 10-win season, but for Andy Reid and company, it was just another year of dominance. However, they weren't perfect. They dropped one high-stakes thriller in the middle of the season and one total head-scratcher at the very end.
The Buffalo Bills Snapped the Undefeated Dream
The biggest headline of the year happened in Week 11. Up until that point, Kansas City was sitting at 9-0. Fans were starting to whisper about a perfect season. Could they actually go 17-0? Then they ran into Josh Allen and the Buffalo Bills at Highmark Stadium.
This wasn't just a loss; it was a statement. The Bills won 30-21, and they did it by being more aggressive when it mattered most. The play everyone remembers is Josh Allen’s 26-yard touchdown run on fourth down. Buffalo could have played it safe and kicked a field goal to go up by five. Instead, Allen tucked the ball and bulldozed his way into the end zone, basically ending the Chiefs' hope for a comeback. Mahomes threw a late interception to Taylor Rapp, and that was that. The 15-game winning streak (counting the previous season) was dead.
It was a classic "Josh Allen versus Patrick Mahomes" duel. While Mahomes threw for three touchdowns, the offense just couldn't keep up with Buffalo's relentless pressure in the fourth quarter. It’s funny how these two teams always find a way to make every game feel like a playoff matchup, even in mid-November.

The Week 18 Shutout in Denver
If the Buffalo loss was a hard-fought battle between heavyweights, the second loss was just... weird. In Week 18, the Chiefs traveled to Denver and got absolutely walloped 38-0.
Wait, 38 to nothing? Yeah.
Before you panic, there’s context. Kansas City had already clinched the #1 seed in the AFC. They had nothing to play for. Because of that, Andy Reid did what he usually does: he rested the starters. Patrick Mahomes, Travis Kelce, and the rest of the "A-team" spent the afternoon on the sidelines in parkas. The Broncos, on the other hand, were playing for pride and a chance to finish the season strong. They took full advantage of the Chiefs' backups.
Does it count as a loss? Technically, yes. Does it tell us anything about the team's strength? Not really. It was basically a preseason game played in January weather. Still, seeing a "0" on the scoreboard for a team led by Andy Reid is always a bit of a shock to the system.

The Heartbreak in Super Bowl LIX
Now, if we are looking at the 2024 campaign—which technically bled into February 2025—the most painful answer to who did Kansas City lose to in 2024 isn't a regular-season opponent. It's the Philadelphia Eagles.
After grinding through the playoffs and beating the Texans and the Bills (revenge is sweet), the Chiefs landed in Super Bowl LIX. The world was watching to see if they could pull off the first "three-peat" in modern NFL history.
They couldn't.
The Eagles won 40-22. It wasn't particularly close toward the end. Philadelphia’s defensive front lived in the Chiefs' backfield, and Mahomes was forced into making uncharacteristic mistakes. He threw two interceptions that the Eagles turned into 14 points. It was a brutal way to end a historic run. Seeing the Chiefs fall short of the three-peat felt like the end of an era, even though we know they'll be back in the mix next year.

Summary of the 2024 Losses
If you just want the quick facts without the fluff, here is how the defeats broke down:
- Week 11: Lost to the Buffalo Bills (30-21). This ended the 9-0 start.
- Week 18: Lost to the Denver Broncos (38-0). Starters were rested.
- Super Bowl LIX: Lost to the Philadelphia Eagles (40-22). The three-peat dream died.
Why These Losses Actually Mattered
You might think a 15-2 season means the losses didn't matter, but that's not quite true. The Buffalo loss changed the narrative. It proved that the Chiefs were vulnerable to a high-octane offense that wasn't afraid to take risks on fourth down. It gave the rest of the league a blueprint: you can't play "not to lose" against Kansas City. You have to go for the throat.
The Denver blowout was mostly a statistical anomaly, but it did show a lack of depth in certain backup positions that the front office probably looked at during the off-season. And the Super Bowl? Well, that loss to Philly showed that even with the greatest quarterback of a generation, a tired offensive line and a lack of explosive plays will eventually catch up to you.
What to Track for Next Season
The Chiefs aren't going anywhere, but the 2024 season taught us that the gap is closing. If you’re following the team into 2025 and 2026, keep an eye on these specific areas:
- Offensive Line Rebuilding: Watch how they protect Mahomes in late-game situations against elite pass rushes like Philly's.
- Wide Receiver Consistency: In 2024, the team leaned heavily on Travis Kelce and Xavier Worthy. They need a more balanced attack to avoid the stagnancy they saw in the Super Bowl.
- The Buffalo Rivalry: This is officially the best rivalry in sports. Mark your calendars for whenever these two play; it usually decides the fate of the AFC.
If you want to stay ahead of the curve, start looking at the 2025 strength of schedule. The Chiefs will have a target on their backs once again, and every team they lost to in 2024 will be looking to prove that those wins weren't flukes.
