The short version
- Who is being sued: Wix.com Ltd., co-founder and CEO Avishai Abrahami, CFO Lior Shemesh, and co-founder and President Nir Zohar.
- What it claims: that they overstated how competitive Wix's AI products were and understated what those products cost, so investors paid too much for Wix shares.
- Who it covers: anyone who bought Wix shares between February 19, 2025 and May 12, 2026.
- Where it stands: early. No court has ruled on the claims. They are allegations, not findings.
- Why customers should care: it describes a company under pressure: AI costs rising, margins falling and the stock down by more than half. In early 2025, Wix's CFO credited its growth partly to its "pricing strategy."
The case
Yappi v. Wix.com Ltd. et al., U.S. District Court for the Northern District of Illinois, No. 1:26-cv-08852, filed July 24, 2026. The plaintiff, Setra Yappi of Cook County, Illinois, sues on behalf of everyone who bought Wix shares in the class period. The claims are under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5, the federal rules against misleading investors.

What the complaint says
It says Wix's leaders told investors throughout the class period that Wix led the market in AI-powered website building. It says that in reality, Wix's costs "were accelerating at an alarming rate as it struggled to maintain its relevance in this market," and that competing AI tools were outpacing Wix's own.
Specifically, it says the defendants failed to disclose that:
- Wix had overstated how competitive and well-performing its AI products were compared with other companies';
- Wix had understated the cost of developing and promoting those AI products;
- so they overstated the commercial and financial benefits of Wix's AI products.
It points to Wix's purchase of Base44, a "vibe coding" app builder, in June 2025, and the launch of Wix Harmony, its flagship AI site builder, in January 2026. It says that on the May 13, 2026 earnings call, Wix's leaders acknowledged that Harmony had "holes" and "missing capabilities," and that professional developers were using competing AI tools.
What Wix's leaders told investors
"We wrapped 2024 with accelerated growth and profitability, driven by successful execution of our product roadmap and pricing strategy as well as strong business fundamentals."
CFO Lior Shemesh, Wix press release, February 19, 2025, quoted in the complaint
"Wix sets a high standard for innovation and creativity, and we're constantly exceeding expectations."

Figures as stated in the complaint, paragraphs 6 to 17.
Where it stands
- July 24, 2026: complaint filed.
- September 22, 2026: investors filed competing motions to be appointed lead plaintiff, the investor who runs the case for the class.
- September 24, 2026: Wix.com Ltd. served.
- October 2026: the parties asked the court to extend the deadline for Wix's response.
As of October 18, 2026, the court has not ruled on the claims. Cases like this usually go next to an amended complaint from the lead plaintiff, then a motion by the defendants to dismiss it.
What it means for Wix customers
This case is about investors, not customers. It won't get anyone a refund. But it shows the pressure behind what customers are seeing:
- Wix credits its pricing for its growth. Its CFO said 2024's growth was driven partly by its "pricing strategy." Customers see that strategy at renewal: in 1,992 recent one-star Trustpilot reviews of Wix, 186 say the price jumped at renewal (the numbers).
- AI is expensive for Wix. The complaint says the cost of Base44, mostly AI computing power and marketing, weighed on Wix's results.
- The money is under strain. Wix's sales are still growing, but its profit and cash have fallen and its stock lost more than half its value (Wix's own filings).
Customers are fighting their own case in a different court. Read what Wix told a US court about renewals.
