As first reported by Front Office Sports, TaylorMade has filed suit against Callaway over alleged false advertising tied to golf ball performance claims.
It’s been a while since we’ve seen a public legal dust-up between two of the golf industry’s true heavyweights—at least one that doesn’t hinge on a patent diagram no one outside a courtroom was ever meant to understand.
In recent history, most of the high-profile equipment lawsuits have come from a familiar cast. PXG sued TaylorMade over adjustable-weighting concepts tied to the P790 era. TaylorMade later went after Costco over the original Kirkland Signature irons.
Beyond that, the last few years have been relatively tranquil, save for a handful of notable exceptions: Foresight (now part of Revelyst) and Uneekor trading blows over camera-based launch monitors, Fujikura pursuing ARETERA on IP grounds and SuperSpeed Golf suing The Stack System over claims related to speed gains.
That calm ended a few days ahead of last week’s PGA Show when TaylorMade Golf Company filed suit against Topgolf Callaway Brands (you can read the full complaint here), alleging false advertising, unfair competition and trade libel tied to Callaway’s marketing of its Chrome Tour golf balls. The complaint was filed in the U.S. District Court for the Southern District of California and seeks injunctive relief, damages, corrective advertising and attorneys’ fees.
Basically, all the things.
When I said golfers would be hearing a lot more about paint in 2026, this ain’t what I meant.
Why imbalance matters
Before getting into the legal back-and-forth, it’s worth grounding this discussion in something both sides probably agree on.
The most basic reason a golf ball flies offline or produces an unexpected trajectory is imbalance.
That imbalance can originate internally (off-center cores, uneven mantle layers, density inconsistencies) or, externally, by way of cover defects.
Over the years, we’ve seen golf balls with missing dimples, gouges, small surface deformities, even areas that appear to have partially melted during the manufacturing process. Any of those issues can compromise the dimple pattern which, in turn, compromises aerodynamics.
A good bit of that is stuff golfers will never notice. Mud, however, is a bit of a different story. Nearly every golfer has had the unfortunate experience of trying to account for a mud ball.
There’s no such thing as a good mud ball. The negative connotation is undeniable.
In its complaint, TaylorMade explains that when mud adheres to one side of a golf ball, it creates asymmetric aerodynamic forces, altering lift and drag and causing the ball to curve unpredictably in flight. In short, mud disrupts the designed airflow and the ball no longer behaves the way it was engineered to behave.
It’s also true that uneven or poorly applied paint can create imbalance and in sufficiently severe cases—regardless of brand—the real-world effects can resemble what golfers experience with mud balls. That doesn’t mean every cosmetic imperfection matters nor does it mean paint issues are the hidden secret that’s ruining your game but it does underscore the broader point: when imbalance reaches a certain threshold, the ball’s flight can become unpredictable.
To reiterate: imbalance—regardless of the source—is bad.
Where the disagreement begins is not whether imbalance matters but whether the specific UV-light demonstrations at issue meaningfully identify performance-relevant imbalance or simply highlight cosmetic differences.
The allegations: UV lights, “mud balls” and performance by association
According to TaylorMade’s complaint, Callaway sales representatives and brand ambassadors have used ultraviolet light demonstrations to suggest that differences in how golf balls appear under UV light correlate directly with on-course performance. In one cited example, a Callaway sales rep allegedly described a perceived paint imperfection on a TaylorMade TP5 as resembling a “gigantic piece of mud” under UV light, implying uneven coating, inferior quality control and unpredictable ball flight.
TaylorMade takes issue with any assertion that its golf balls will fly like mud balls and characterizes these demonstrations as a “marketing contrivance,” arguing they show only that Callaway uses more UV brightener in more coating layers than TaylorMade—and nothing about distance, consistency or dispersion. The company contends UV brightness and cosmetic appearance under black light have no reliable relationship to real-world golf ball performance.
To our knowledge, Callaway has not yet formally responded to the allegations.
Shout out to MyGolfSpy
The complaint also turns its attention to media coverage and specifically cites a MyGolfSpy article published on Jan. 6, 2026. It’s my story on the new Chrome Tour, Chrome Tour X, and Chrome Soft golf balls.
In its complaint, TaylorMade describes MyGolfSpy as:
“a popular digital golf platform that reaches approximately 22 million golfers/consumers, 7 million of which are estimated to be dedicated golfers most likely to be a core audience for premium, high-performance golf balls.”
(Thank you so much for the recognition. You’re too sweet.)
Where clarification is required is in TaylorMade’s characterization of the article itself.
Our original piece does mention UV light but it did so narrowly. The article did not claim that UV testing is a definitive measure of golf ball performance nor did it present UV response as a consumer-facing replacement for a microscope or real-world testing.
The story does not mention TaylorMade.
It’s also worth adding some context: Callaway isn’t the first company to suggest UV light as a way to evaluate paint uniformity. Several years ago, Wilson made similar points during the launch of its raw Staff and Staff Model X golf balls, explicitly discussing how paint can introduce defects during the finishing process—and how removing paint altogether eliminates that risk. Some of what we saw then also involved UV lights.
The UV light and golf ball thing isn’t exactly new.
What comes next
We talked about paint in our Callaway story and unless the story changes before TaylorMade lifts its next golf ball embargo, we’ll do the same—including any relevant discussion around paint.
So yeah, more to come as TaylorMade takes its turn in the release cycle.
At this stage, it’s important to emphasize what this is: a complaint, not a conclusion.
TaylorMade has laid out its argument that Callaway’s UV demonstrations misrepresent performance and disparage TP5. Callaway will respond, and maybe the facts will be tested in court rather than under a black light.
Maybe this all goes away. It’s too soon to say.
More info as it becomes available.
