Top Class Action Settlements Expiring in May 2026 — Over $1.5 Billion

May 2026 brings some of the most significant class action settlement deadlines of the year — including a $1.225 billion merchant payment settlement and a $179 million securities class action. Whether you're a consumer, a business owner, or an investor, there's a very good chance at least one of May's biggest settlements applies to you. Here's the complete breakdown.

1. Discover Card Merchant Settlement — $540M to $1.225 Billion (Deadline: May 18, 2026)

This is the biggest deadline of the month — and potentially one of the largest consumer/business settlements of 2026. Discover Financial Services agreed to settle claims that it improperly classified merchant interchange fees over a 16-year period from 2007 to 2023.

Any U.S. merchant that accepted Discover card payments during that period may qualify for a pro-rata share of the settlement fund. No receipts or business records are required — self-attestation is sufficient. The minimum settlement fund is $540 million, which means even in a high-claims scenario, individual payouts remain meaningful.

This settlement is frequently compared to the Visa/Mastercard merchant interchange settlement — the largest antitrust class action in U.S. history. Don't dismiss it as "a business thing." Sole proprietors, freelancers, side-business owners, and anyone who ever processed a card payment as a merchant should check eligibility.

2. Acadia Healthcare Securities Settlement — $179 Million (Deadline: April 30, 2026)

This investor-focused settlement resolves claims against Acadia Healthcare — a behavioral health company — for alleged securities fraud. The class action alleged that Acadia made materially false and misleading statements that artificially inflated the company's stock price between April 2014 and November 2018.

The $179 million fund is substantial. Eligible investors who purchased Acadia Healthcare common stock during the class period and sustained losses may be entitled to a meaningful recovery. This settlement requires proof of investment (brokerage statements showing your purchases and losses), but the calculation is straightforward if you held the stock during the qualifying window.

Who qualifies: Anyone who purchased or otherwise acquired Acadia Healthcare Co. (ACHC) common stock between April 30, 2014, and November 15, 2018, and held through the class period end date.

3. BFI Waste Services Price Gouging Settlement — $40 Million (Deadline: April 30, 2026)

Commercial businesses in eight states have until April 30 to claim their share of a $40 million settlement with BFI Waste Services (a subsidiary of Republic Services). The lawsuit alleged BFI raised prices beyond what their contracts allowed — effectively charging customers for cost increases they weren't contractually entitled to pass through.

Eligible businesses include commercial and industrial customers in Florida, California, Illinois, South Carolina, Michigan, Ohio, Indiana, Pennsylvania, Massachusetts, and Jefferson County, Alabama who had BFI waste or recycling service contracts between 2017 and 2025. Payouts of $100 to $250 are available with no documentation required for base-tier claims.

4. Southwest Airlines Military Leave Settlement — $18.5 Million (Deadline: April 28, 2026)

Southwest Airlines agreed to pay $18.5 million to resolve allegations that it violated USERRA (the Uniformed Services Employment and Reemployment Rights Act) by failing to properly compensate employees during short-term military leave. The law requires employers to treat employees on military leave at least as favorably as employees on comparable forms of non-military leave.

This settlement is time-sensitive — the April 28 deadline is only days away. If you are a current or former Southwest Airlines employee who served in the military and took short-term leave during the qualifying period, file immediately.

5. McLaren Health Care Data Breach Settlement — $14 Million (Deadline: April 29, 2026)

McLaren Health Care — one of Michigan's largest hospital systems — experienced not one but two ransomware attacks in 2023 and 2024, compromising the personal and health information of approximately 2.8 million patients. The combined $14 million settlement provides:

• Up to $5,000 for documented out-of-pocket losses
• A flat cash payment for undocumented claims (no proof needed)
• Two years of credit monitoring and identity restoration services

Healthcare data breaches are among the most serious — they expose not just financial data but your entire medical history, insurance information, and Social Security number. The settlement reflects that gravity. If you received a breach notification from McLaren Health Care for either the 2023 or 2024 incident, you qualify.

→ File the McLaren Health Care Claim by April 29, 2026

6. Signature Performance Data Breach Settlement — $8.5 Million (Deadline: May 7, 2026)

Signature Performance — a healthcare revenue cycle management company — suffered a data breach in January 2024 that exposed the personal and health information of both patients and employees at affiliated healthcare systems including Adventist Health. The $8.5 million settlement covers eligible individuals who received notification of the breach.

Claimants can receive up to $5,000 for documented losses plus three years of credit monitoring. The May 7 deadline gives you about two weeks — more time than most of the April-closing settlements, but not much.

→ File the Signature Performance Claim by May 7, 2026

7. Trader Joe's FACTA Receipt Settlement — $7.4 Million (Deadline: June 9, 2026)

This one is for regular Trader Joe's shoppers. The Fair and Accurate Credit Transactions Act (FACTA) requires that printed receipts truncate credit and debit card numbers. Trader Joe's allegedly printed receipts that violated this requirement between March 5 and July 19, 2019.

Each eligible claimant can receive approximately $102.45. You simply need to attest that you made a credit or debit card purchase at Trader Joe's during the qualifying period. No receipt required — the claim form is simple and takes about 3 minutes.

June 9 feels far away right now. It isn't. File this one while you're filing the April and May settlements.

How to Prioritize When Multiple Deadlines Overlap

With multiple settlements closing in the same week, here's how to work through them efficiently:

File by Urgency First

Sort by deadline date. April 28 (Southwest Airlines) before April 29 (McLaren), before April 30 (BFI Waste, Acadia, Equity Residential). Then May 7 (Signature Performance), then May 18 (Discover), then June 9 (Trader Joe's).

Batch Similar Claims

Data breach claims (McLaren, Signature Performance) require similar information — your name, contact info, and confirmation that you received a breach notice. File them back to back to reduce mental friction.

Keep Confirmation Emails

Create a folder in your email client labeled "Settlement Claims 2026." Drop every confirmation email in there. You'll need these reference numbers if a payment is delayed or if you need to follow up.

Key Takeaways

• May 2026 features over $1.5 billion in total settlement funds across active claims

• Acadia Healthcare ($179M) and BFI Waste ($40M) close April 30

• The Trader Joe's FACTA settlement ($102.45) closes June 9 — file while you're at it

There is no reason not to file every settlement you qualify for. These are court-approved funds set aside specifically for people in your situation. The only thing standing between you and the money is a 10-minute claim form.
