Sen. Bernie Sanders threw his support behind New York City Mayor Zohran Mamdani’s push for the Delivery Protection Act on Tuesday, accusing Amazon.com, Inc. of exploiting "legal loopholes" to deny workers union rights despite generating more than $92 billion in the first half of the year. The legislative effort, introduced by City Council Member Tiffany Caban, seeks to license last-mile delivery facilities and hold Amazon accountable for its subcontractor network, escalating political pressure on the e-commerce giant amid concerns over labor standards.

The Delivery Protection Act mandates that operators of last-mile delivery facilities obtain licenses through the city's Department of Consumer and Worker Protection. The bill specifically targets Amazon's structure involving Delivery Service Partners (DSPs), independent businesses that employ drivers to deliver Amazon packages. This arrangement creates a layer between Amazon and the workers, shielding the company from direct accountability under current regulations. Mamdani stated in an announcement video posted on X that if Amazon is delivering packages, it should follow the same rules as any other delivery company.

Amazon is pushing back against the proposal, with spokesperson Kelly Nantel telling Business Insider that the legislation could put more than 5,000 jobs at risk. In testimony before New York City officials, Amazon said the bill could disrupt agreements with more than 40 local DSPs that employ thousands of New Yorkers. A coalition representing 50 small delivery businesses also opposed the legislation, warning lawmakers about its potential impact on family-owned companies. Amazon invited all City Council members to visit its delivery stations and meet with contractors before voting on the bill.

Market Reaction

Amazon shares closed at $272.27 on Tuesday, down 2.09%. In after-hours trading, the stock was at $272.26. Benzinga Edge ranks Amazon in the 91st percentile for Growth, noting a positive price trend across short-, medium-, and long-term horizons. This follows Monday’s close at $278.09, up 1.32%, before dipping to $277 in after-hours trading.

What the Numbers Show

Sanders’ citation of Amazon’s $92 billion first-half profit highlights the financial scale behind the company’s operational model, contrasting sharply with the municipal focus on worker protections. The rapid expansion of physical infrastructure—18 new facilities between 2017 and 2025—underscores the tangible growth driving regulatory scrutiny. Meanwhile, the opposition from 50 small businesses indicates that the DSP model is deeply embedded in the local economy, suggesting that any regulatory shift could disrupt established supply chains and employment structures beyond just Amazon’s direct workforce.
