At this year's U.S. Open tennis tournament, IBM is using its Watsonx software development platform to generate live AI insights through the official app, tracking key moments and player data such as serve quality and likelihood to win. According to IBM technical program director Tyler Sidell, over a billion data points will be produced by the end of the tournament. Players like Jessica Pegula are also using the AI features to identify patterns in their opponents' serves before matches. The "likelihood to win" feature has been available through the app for about six years and allows fans to track real-time odds as a match plays out.

But at the U.S. Open this year, the digital world has become intertwined with the game as live AI insights reshape the tournament experience.
asserted
insights → become → experience
On Tuesday night, when Coco Gauff faced off against Zeynep Sönmez of Turkey, AI-generated analysis trickled in through the U.S. Open app, tracking key moments, each player's likelihood to win and a new metric called "serve quality."
Cameras lining the perimeter of Arthur Ashe Stadium track the ball, racket and players' limbs, collecting data points like elbow and knee flexion and wrist flex velocity.
asserted
Cameras → face → flexion
Then, IBM's agentic software development platform, Watsonx, processes the data from the court to measure the efficiency, accuracy and consistency of a player's serve, a number out of 100 that can be seen in the U.S. Open app postmatch.
asserted
that → process → postmatch
Gauff's winning serves had a "controlled racket preparation and deep knee bend during her setup," according to the serve quality summary.
uncertain
serves → win → summary
There will be over a billion data points produced by the end of the tournament, said Tyler Sidell, IBM's technical program director for sports and entertainment partnerships.
asserted
Sidell → produce → partnerships
The data-driven experiences, he said, are meant to be a conversation starter for fans.
asserted
he → drive → fans
"There's so much unpredictability in sports — you could take a look at all the data, but anything can happen out there on the court," he said.
uncertain
he → be → court
We want to provide an insight, but still, let's watch the matches play out.
asserted
matches → want → insight
AI insights are not just about the fans who can access them in the app (about 14 million of them, according to IBM).
uncertain
who → access → IBM
The features have also become a tool for players.

Jessica Pegula, who advanced to the fourth round of the U.S. Open on Friday, uses AI to identify patterns in her opponents' serves before facing them in a match.
asserted
who → advance → match
"Tennis is a lot of problem solving on the court, so it's a lot of patterns, and I think serve is a really big one," she told CBS News.
asserted
she → think → News
"It's the one controllable shot we have in tennis."
asserted
we → have → tennis
Although the game can turn around at any moment, for Pegula, the data remains useful.
asserted
data → turn → Pegula
"You can get a lot of analytics, but sometimes things change during the match, sometimes someone changes their strategy, or they maybe go against the grain of what you thought they were going to do, and you still have to really trust your instinct," she said.
asserted
she → get → instinct
"But I think mentally it just gives you that feeling of being prepared before you go into a match."
asserted
you → think → match
The "likelihood to win" feature has been a staple of the U.S. Open digital experience for about six years, Sidell said, but this is the second year fans can track the fluctuating likelihoods in real time as a match plays out.
asserted
match → win → time
The feature is built on trusted media sources and recent performances, which are aggregated to generate a player's odds of winning.
asserted
which → build → odds
Gauff was predicted to win Tuesday by 72%, a number that rose as she built momentum in the first set.
asserted

Another AI-powered feature, "key moments," provides brief blurbs of analysis as a game unfolds.
