Fidelity Investments recently won an important investor lawsuit involving fees charged by the Fidelity Government Money Market Fund.
On March 25, 2026, a federal judge dismissed a proposed class action accusing Fidelity of keeping investors in a higher-cost share class even after their account balances became large enough to qualify for a lower-cost share class.
The case is important for Fidelity investors because it involved allegations that investors were paying unnecessary fees when they could have been moved into a cheaper share class.
However, the court did not find that Fidelity overcharged investors. Judge Margaret Garnett ruled that Fidelity’s disclosures were adequate and that investors had the ability to convert their shares themselves.
What Is the Fidelity Investor Lawsuit About?
The lawsuit involved the Fidelity Government Money Market Fund, a large money market fund managed by Fidelity.
Investors alleged that Fidelity should have automatically moved eligible investors from a retail share class into a lower-cost premium share class once their account balances reached certain thresholds.
According to the lawsuit, investors could remain in the more expensive share class even after becoming eligible for the cheaper option.
The plaintiffs argued that this allowed Fidelity to collect higher fees than necessary.
Why Were Investors Paying Higher Fees?
The dispute centered on two different share classes.
The retail share class charged expenses of up to approximately 0.42%, while the premium share class charged up to approximately 0.32%.
Investors alleged that the difference resulted in millions of dollars in additional fees for people who were eligible for the cheaper class but were not automatically converted.
The eligibility thresholds discussed in the lawsuit were:
| Account type | Balance threshold |
| Non-retirement account | $100,000 |
| Retirement account | $10,000 |
Once an investor reached the applicable threshold, the plaintiffs argued that Fidelity should have automatically moved the investor to the lower-cost share class.
Who Filed the Fidelity Lawsuit?
The proposed class action was filed by investors Bryan Davis and Ethan Sam.
The lawsuit was filed on October 25, 2024, in the U.S. District Court for the Southern District of New York.
The defendants included Fidelity Management & Research Company and other parties connected with the fund.
The case is generally identified as Davis v. Fidelity Management & Research Company LLC.
What Did the Investors Accuse Fidelity Of Doing?
The plaintiffs brought several claims.
They alleged that Fidelity and other defendants:
- Failed to automatically convert eligible investors into the cheaper share class
- Allowed investors to pay higher expenses unnecessarily
- Breached fiduciary duties
- Violated the implied covenant of good faith and fair dealing
- Were unjustly enriched by the additional fees
The plaintiffs argued that Fidelity benefited financially by maintaining investors in the higher-cost share class.
These were allegations made by the plaintiffs and were not ultimately accepted by the court.
What Did Fidelity Say?
Fidelity defended its fund structure and disclosures.
The company argued that investors were informed about the different share classes and the process for converting shares.
The case ultimately turned on whether Fidelity had a legal obligation to automatically convert qualifying investors.
Why Did the Judge Dismiss the Lawsuit?
U.S. District Judge Margaret Garnett dismissed the lawsuit on March 25, 2026.
The judge concluded that the plaintiffs had not established a viable legal claim.
A key part of the ruling was that Fidelity had adequately disclosed the economic consequences of remaining in the retail share class and the availability of conversion.
Investors also had the ability to convert their shares themselves.
The judge therefore concluded that it was not unreasonable for Fidelity to operate the fund without an automatic conversion feature.
Did Fidelity Win the Lawsuit?
Yes.
The federal judge dismissed the investors’ lawsuit.
This means Fidelity successfully defeated the claims at this stage of the litigation.
It is important to say “the lawsuit was dismissed” rather than saying that a court proved the investors were wrong about every factual allegation. The ruling means the plaintiffs did not establish legally sufficient claims under the theories they brought.
Is There a Fidelity Money Market Fund Settlement?
No settlement payment resulted from this lawsuit.
Because the judge dismissed the case, there is no class-action settlement fund for investors based on the claims in this particular case.
This is different from another Fidelity-related class action involving a 2024 data breach, which resulted in a separate $2.5 million settlement. That cybersecurity case is unrelated to the money market fund fee lawsuit.
Is This the Same as the Fidelity Data Breach Settlement?
No.
There are multiple legal matters involving Fidelity, and they should not be confused.
Money Market Fund Lawsuit
The case discussed in this article involved allegations about:
- Fidelity Government Money Market Fund
- Share classes
- Investment fees
- Automatic conversion
- Fiduciary duties
Fidelity won this case when the judge dismissed the lawsuit in March 2026.
Fidelity Data Breach Settlement
A separate case involved a 2024 cybersecurity breach affecting more than 77,000 people.
That case resulted in a $2.5 million class-action settlement, with eligible individuals potentially able to receive compensation under the settlement terms.
These are completely different cases.
How Much Money Were Investors Claiming?
The plaintiffs alleged that investors collectively lost millions of dollars through additional fees.
The difference between the cited expense ratios was approximately:
0.42% − 0.32% = 0.10 percentage points
The actual amount paid by an individual investor would depend on the amount invested and how long the investor remained in the higher-cost share class.
However, because the lawsuit was dismissed, there is no court-approved reimbursement program for these alleged fee differences.
Does the Ruling Mean Fidelity’s Fees Were Illegal?
No.
The court did not rule that Fidelity’s fees were illegal.
Instead, the judge determined that the plaintiffs had not successfully established their legal claims against Fidelity.
The court also found that Fidelity had adequately disclosed the relevant information and that investors could convert their shares themselves.
What Is the Fidelity Government Money Market Fund?
The Fidelity Government Money Market Fund is a money market mutual fund that invests primarily in government securities and related instruments.
It is also important in the Fidelity ecosystem because the fund’s retail share class is used as a cash-management option for many Fidelity customers.
The fund was enormous at the time of the litigation. Reuters reported that it had approximately $439.1 billion in assets, with about $406.4 billion in the retail share class as of February 28, 2026.
Why Does the Lawsuit Matter to Fidelity Investors?
The lawsuit highlights an important issue for investors: different share classes of the same or similar fund can have different expenses and eligibility requirements.
Investors should understand:
- Which share class they own
- What expense ratio applies
- Whether they qualify for another share class
- Whether conversion is automatic
- Whether they need to request a conversion
- What minimum balance requirements apply
The court’s ruling does not mean investors should ignore fees.
Rather, it emphasizes the importance of understanding the fund’s rules and disclosures.
Is Fidelity Being Sued by Investors?
Fidelity has faced multiple legal disputes, so it is important to identify the specific case.
The money market fund fee lawsuit was dismissed in March 2026.
At the same time, Fidelity has been involved in other unrelated litigation and regulatory matters.
For example, a separate FINRA arbitration in February 2026 resulted in an approximately $1.29 million award against Fidelity Brokerage Services involving structured-product sales.
That arbitration is not the same case as the money market fund lawsuit.
