April 20 (Reuters) - Amazon.com AMZN.O worked behind the scenes with merchants such as Levi Strauss LEVI.N to prod online rivals such as Home Depot HD.N, Walmart WMT.O and Chewy CHWY.N to raise prices for consumers so it would not be undercut, California's attorney general said on Monday.

Evidence detailing alleged efforts to fix prices was unsealed on Monday, as part of Attorney General Rob Bonta's 3 1/2-year-old antitrust lawsuit against Amazon. The lawsuit also seeks to recoup what Bonta called ill-gotten profits. A trial is scheduled for January 19, 2027.

"Amazon is illegally working to rake in the profits by making sure consumers have nowhere else to turn to for lower prices," Bonta said in a statement.

The Seattle-based retailer did not immediately respond to a request for comment. Amazon is the only defendant in the suit.

In a filing in San Francisco Superior Court, California described dozens of cases of alleged price-fixing that boosted prices for goods such as khaki pants, fertilizer, eye drops and dog treats.

Bonta has said the alleged collusion leads merchants and rivals to raise prices or make products temporarily unavailable so Amazon wouldn't have to price match.

The filing described Levi Strauss' alleged effort to persuade Walmart to charge $29.99 for Easy Khaki Classic pants after Amazon expressed "concern" with Walmart's original $25.47 price.

California said Amazon's complaint about lower fertilizer prices prompted Home Depot's agreement "to raise the prices this time," while Amazon pushed Allergan, now part of AbbVie ABBV.N, to see if Walmart would charge $16.99 for eye drops so it wouldn't have to price match at $13.59.

The filing also described Amazon's alleged effort to break a price match with Chewy, the online pet supply retailer, for Canine Naturals pet treats. “(Prices) that went up on Amazon immediately went up on Chewy," an intermediary merchant wrote, adding a smiley-face emoji. "Overall this looks like it’s working!"

Amazon has said its agreements with merchants are legal and benefit consumers through increased product selection, appropriate stocking and competitive prices.

The company's revenue in 2025 surpassed that of Walmart, long the world's largest retailer by revenue.

Bonta is seeking an injunction to stop Amazon's alleged price-fixing while the case is pending. A July 23 hearing is scheduled.
