Here are some of the more recent and notable class-action items involving Fidelity that have shown up in news—though “Fidelity class action lawsuit” is broad, and there may be multiple different cases (consumer, data breach, retirement-plan/fees, etc.).
Data-breach class action (Fidelity Investments)
A class action was reported in October 2024 alleging Fidelity failed to adequately protect its network during an August data breach and that customers’ data was compromised. The case was filed in Massachusetts federal court and seeks nationwide class treatment.[3]
401(k) / retirement-plan fee allegations (older, but still referenced)
Earlier reporting (2019) says FMR LLC (Fidelity’s parent) agreed to class certification in a lawsuit challenging the use of in-house mutual funds in Fidelity’s 401(k) plan, with the class covering participants from 2014 onward.[5]
Other lawsuit strands (older/less directly “latest”)
There are also past reports of litigation involving Fidelity’s retirement products and alleged fiduciary breaches and related defenses, but those are not “latest” to 2026 based on what I can see from the surfaced items.[4]
Quick clarifying question
Which “Fidelity” do you mean, and what type of lawsuit?
- Fidelity Investments (brokerage/retirement plans) vs Fidelity National Information Services (FIS) vs another Fidelity entity
- Topic: data breach, 401(k)/fees, false advertising, or something else
Reply with those details and I’ll narrow to the most recent filings/updates for the exact case you mean.
