Amazon Sellers Face Triple Threat in 2026

The FTC Lawsuit: Allegations of Hidden Ad Auction Pricing

The Federal Trade Commission, joined by 22 state attorneys general, has filed a lawsuit against Amazon alleging that the company secretly inflated what advertisers paid for Sponsored Ads by using undisclosed “soft reserve” prices in its ad auctions. According to the complaint, Amazon’s practice affected over 1.2 million advertising customers and generated tens of billions of dollars for the company since 2019. The suit, filed on September 1, 2026, claims Amazon extracted at least $20 billion through these hidden surcharges without advertisers’ knowledge. Amazon has not yet issued a public response to the allegations.

This lawsuit is the most significant regulatory action against Amazon’s advertising business to date. For sellers who rely on Sponsored Products to drive visibility, the allegations raise serious questions about whether their ad budgets have been wasted on artificially inflated costs. If the FTC prevails, Amazon could be forced to overhaul its ad auction system, potentially lowering costs for sellers—but also introducing new uncertainties. The case is likely to take months or years to resolve, but the immediate effect is increased scrutiny on Amazon’s ad platform and a shift in seller confidence.

Amazon’s New FBA Fee Structure: What Changed on September 1

The key change for sellers is that Amazon’s updated Fulfilled by Amazon (FBA) fee structure fully took effect on September 1, 2026. The new rules introduce two major cost pressures: low-inventory surcharges and revised inbound placement fees. The low-inventory surcharge applies when a seller’s stock falls below a threshold relative to recent sales, penalizing those who run lean inventory. The inbound placement fee, which charges sellers for distributing inventory across fulfillment centers, has also been restructured, making it more expensive to send small shipments or to ship from certain regions.

These changes disproportionately affect products priced under $15, where shipping and handling fees already consume a large portion of the margin. Early seller reports indicate that low-inventory surcharges can add 10–20% to fulfillment costs for popular items during restocking gaps. The new fee structure is reshaping seller math heading into Q4 2026, forcing many to reevaluate their inventory planning and pricing strategies.

Record High CPCs: Why Ad Costs Are Climbing

Average cost-per-click (CPC) for Amazon Sponsored Products reached a record high of $1.94 in Q2 2026, a 22% increase year-over-year. This surge makes it increasingly difficult for sellers to maintain a positive return on ad spend (ROAS), especially those with thin margins or low-priced products. The rising CPCs are driven by several factors: more sellers competing for the same keywords, Amazon’s own ad inventory expansion, and the broader shift of retail dollars to ecommerce advertising. In the current environment, a seller with a product priced at $20 might need a conversion rate above 10% just to break even on ad costs, a tall order for many categories.

The CPC data underscores the urgency for sellers to optimize their advertising strategies. Manual targeting, negative keyword lists, and dynamic bidding have become table stakes. Yet even the most efficient campaigns are feeling the pinch. Read the full Q2 2026 CPC analysis from Ecommerce Times.

The Combined Impact on Seller Margins

When viewed together, these three developments create a perfect storm for Amazon sellers. Let’s compare the key cost pressures:

Cost Factor	Specific Impact	Key Date	Estimated Cost Effect
FTC lawsuit (alleged hidden ad surcharges)	Inflated ad auction prices, lack of transparency	Lawsuit filed Sept 1, 2026	$20+ billion extracted from advertisers since 2019
New FBA fee structure	Low‑inventory surcharges, revised inbound placement fees	Effective Sept 1, 2026	10–20% added fulfillment cost for affected items
Record CPCs	Sponsored Products average CPC = $1.94 (Q2 2026)	Q2 2026; ongoing	22% YoY increase, squeezing ROAS

Sellers who rely heavily on advertising and FBA are seeing their costs rise from multiple angles simultaneously. A typical seller with a $25 product, using FBA and running Sponsored Products, could see their total fulfillment and ad costs exceed 40% of the product price—up from roughly 30% a year ago. This margin compression is forcing sellers to either raise prices, reduce ad spend, or seek alternative fulfillment methods such as fulfilled by merchant (FBM) or third-party logistics.

The FTC lawsuit adds another layer of uncertainty. If sellers suspect that their ad dollars were previously inflated by hidden soft reserves, they may pull back on spending until the outcome is clearer. That could temporarily lower auction competition and reduce CPCs, but it also risks losing organic ranking and sales velocity.

How Sellers Are Adapting to the New Reality

In response to these pressures, sellers are adopting a mix of short-term tactics and long-term strategy shifts. Many are reconfiguring their inventory management to avoid low-inventory surcharges by maintaining higher safety stock levels, even if that means higher warehousing costs. Others are testing smaller, more frequent inbound shipments to minimize placement fees. On the advertising side, sellers are increasingly shifting budget toward Amazon’s demand-side platform (DSP) for more targeted reach, or experimenting with AI-driven bid optimization tools.

Diversification is also a growing trend. Sellers who previously relied exclusively on Amazon are expanding to Walmart Marketplace, eBay, or their own direct-to-consumer sites. However, Amazon remains the largest sales channel, so most are choosing to optimize rather than abandon the platform. For example, some sellers are raising prices on Amazon to offset higher costs while keeping prices lower on other channels to maintain competitiveness.

Another emerging strategy is product bundling, which allows sellers to increase average order value and spread ad costs across more items. For products under $15, bundling with complementary items can push the total above the threshold where the new FBA fees become less punitive.

Looking Ahead: What’s Next for Amazon Sellers

The near-term outlook for Amazon sellers is challenging but not hopeless. The FTC lawsuit could lead to reforms that ultimately lower ad costs, but that resolution is likely years away. Similarly, Amazon may adjust its fee structure in response to seller backlash, as it has done in the past. In the meantime, sellers must focus on what they can control: data-driven inventory planning, efficient advertising, and margin optimization.

The fourth quarter of 2026 will be a critical test. With holiday demand high and costs elevated, sellers who can maintain profitability will emerge stronger. Those who fail to adapt may be pushed out, consolidating the marketplace around more sophisticated operators. For anyone selling on Amazon, the lesson is clear: the days of easy growth are over, and survival now depends on mastering the complex interplay of fees, ad costs, and regulatory risk.
