Netflix is teaming up with Amazon, and it's dragging down adtech rival The Trade Desk's stock

Netflix announced a partnership allowing advertisers to buy ads on its platform via Amazon DSP starting Q4, a significant development intensifying competition in the connected-TV adtech space. This move is a considerable blow to The Trade Desk (TTD), leading Morgan Stanley to downgrade its stock to equal-weight with a reduced price target of $50 from $80, citing increased competition and execution concerns. TTD shares subsequently fell over 10% on the news and are now down over 60% year-to-date, highlighting Amazon's aggressive expansion challenging TTD's market position.

Analysis

The partnership enabling advertisers to purchase Netflix inventory via Amazon's DSP represents a significant escalation in the connected-TV (CTV) adtech landscape, directly challenging The Trade Desk's (TTD) market position. This move is not an isolated event but part of a broader, aggressive strategy by Amazon, which has recently secured similar deals with major players like Roku and Disney, systematically eroding TTD's competitive edge in the high-growth CTV segment. The market and analyst community have reacted decisively to this threat. Morgan Stanley downgraded TTD stock from overweight to equal-weight, slashing its price target to $50 from $80, citing intensifying competition from Amazon's DSP, execution concerns, and a softer ad market. This sentiment was immediately reflected in TTD's stock, which fell over 10% on the news and is now down over 60% year-to-date. The stark contrast between TTD CEO Jeff Green's prior assertion that "Amazon is not a competitor" and the prevailing analyst view that TTD is "glaringly obvious... under attack" highlights a critical disconnect and suggests the company may be losing control of its narrative.

Key Decisions for Investors

• Investors in The Trade Desk (TTD) should re-evaluate the company's long-term competitive moat, as Amazon's aggressive expansion into the CTV ad space, validated by key partnerships, presents a material and escalating threat to market share.
• Given the Morgan Stanley downgrade and the stock's significant year-to-date decline of over 60%, initiating or adding to a long position in TTD carries heightened risk until the company demonstrates a credible strategic response to Amazon's encroachment.
• For investors in Amazon (AMZN), this development reinforces a bullish outlook on its advertising business, validating its strategy to compete directly with Google and TTD to become a dominant demand-side platform.
• The partnership is a net positive for Netflix (NFLX), as it broadens the pool of advertisers able to access its inventory, potentially accelerating the growth and monetization of its ad-supported subscription tier.
