US latest news September 15, 2026: stock market, technology news, sports, weather today, who won Monday Night Football, Starbucks fall collab and more

From Wall Street and artificial intelligence to the return of fall-themed Starbucks merchandise and the latest Monday Night Football action, several topics are drawing attention across the US on Tuesday, September 15.

Here is a look at some of the biggest US-related stories and search trends today.

US technology news today


Artificial intelligence remains at the centre of the US technology conversation, with concerns about the pace of AI development increasingly spilling into the financial markets.

Microsoft has also announced a set of AI privacy commitments focused on students as schools return for the new academic year. The company’s move comes amid a broader debate over how artificial intelligence should be used in classrooms and how student data should be protected.

The AI debate has also intensified after Anthropic CEO Dario Amodei called for a slowdown in the development of increasingly powerful AI systems. The comments have added to wider concerns among technology leaders about AI safety, investment and the potential risks associated with rapidly advancing systems.

Meanwhile, Oracle has started another round of layoffs.

US weather today

Tuesday, September 15, is expected to bring heavy rain and thunderstorms across parts of the Plains and Great Lakes, with localized flooding emerging as the main weather concern. AccuWeather meteorologists said rain and thunderstorms stretching from the Plains to the Great Lakes could produce enough rainfall to cause flooding, particularly from southeastern Nebraska through Iowa and into west-central Illinois.

Cities including Chicago, Kansas City and Milwaukee could see rounds of heavy rain through Tuesday and into Wednesday night, with some areas potentially receiving several inches. A few thunderstorms could also produce small hail and blustery winds, especially from eastern Kansas to southern Michigan. The heavy rain could lead to ponding on roads, travel disruptions and delays to the fall harvest because of soggy fields. Elsewhere, the interior West is expected to see a resurgence of monsoon storms, bringing risks of localized flooding, damaging winds, lightning and dust storms, while the Southeast should experience a relative break from the frequent thunderstorms seen in recent days.

Stock market today: Dow, S&P 500 and Nasdaq

On Monday, September 14, the S&P 500 fell 0.5% to 7,619.98, while the Dow Jones Industrial Average declined 0.3% to 52,421.20. The Nasdaq Composite dropped 0.6% to 26,186.41. The sell-off was partly linked to weakness in AI-related stocks following renewed debate about the pace of AI investment. Rising oil prices and a jump in the 10-year US Treasury yield to 5% also added pressure to markets.

On Tuesday, US stock futures may remain under pressure as investors looked ahead to the Federal Reserve's latest policy decision and oil prices closely. September S&P 500 E-Mini futures (ESU26) are down -0.32%, and September Nasdaq 100 E-Mini futures (NQU26) are down -0.35% this morning as rising oil prices pushed bond yields higher, sapping risk appetite. The 10-year T-note yield rose three basis points to 5.02%.

Who won Monday Night Football?

The Kansas City Chiefs won Monday Night Football on September 14, 2026, defeating the Denver Broncos 31–10 at Arrowhead Stadium. The standout was Kenneth Walker III, who rushed for 173 yards and two touchdowns in his Chiefs debut. Patrick Mahomes also made his return from a knee injury, throwing two touchdown passes and rushing for another.

Starbucks fall collaboration: Snoopy and Peanuts

Starbucks is also leaning into the arrival of fall with a new collaboration with Peanuts.

The limited-edition collection, inspired by the classic Halloween special It's the Great Pumpkin, Charlie Brown, launches September 15. The collection features Snoopy, Woodstock, Charlie Brown and other Peanuts characters across drinkware, accessories and merchandise.

The collection includes 10 items, including a Snoopy glass cold cup, tumblers, mugs, a Snoopy plush, bag charm, mini tote and enamel pin set.

The Snoopy glass cold cup is priced at $39.95 in the US, while other items include a $32.95 stainless-steel cold cup, a $29.95 ceramic mug and a $34.95 Snoopy plush. Availability is limited and varies by market.

The collaboration also coincides with the 60th anniversary of It's the Great Pumpkin, Charlie Brown, giving Starbucks another way to connect its seasonal fall lineup with a familiar piece of American pop culture.
