Publishers, Build Your Own SSP!

This article proposes that publishers build their own white-label SSP to unlock direct relationships with bidders and DSPs, increasing revenue and control. By integrating an additional SSP path via OpenRTB, publishers can generate more impressions and optimize their existing ad stack, similar to header bidding. The article details technical considerations such as QPS, ads.txt, and sellers.json, and highlights the potential for cost transparency and reduced fragmentation. It also suggests using the publisher-SSP to review reseller paths and manage data sharing. Ultimately, the approach enables publishers to become more active participants in the ecosystem, working directly with DSPs like The Trade Desk's OpenPath initiative.

• Publishers can build a white-label SSP to create direct connections with bidders and DSPs.
• White-label SSPs operate via OpenRTB and integrate into the existing ad stack.
• The article identifies Prebid, Amazon TAM, and Google Open Bidding as common connection options.

Wall Street's Disillusionment with The Trade Desk

The Trade Desk has suffered a dramatic decline, with its stock down 90% from its peak and market cap dropping to roughly one-tenth of its December 2024 high of $70 billion, leading to its removal from the S&P 500. The company faces multiple headwinds: a 15% companywide layoff after disappointing Q3 earnings, lowered forecasts, and near-total C-suite turnover. Analysts attribute the downturn to increased competition from challenger DSPs like Viant and Pontiac Intelligence, the shift of ad budgets to walled gardens (Google, Meta, Amazon), and the potential disintermediation of DSPs by agentic platforms like Google's Buyer Direct. Investor concerns over CEO Jeff Green's super-majority control add to skepticism, making an acquisition unlikely despite a sub-$10 billion valuation. The broader ad tech industry now favors large, media-owning platforms over independent players.

• The Trade Desk's stock is down 90% from its high, with market cap at about one-tenth of its December 2024 peak of $70 billion, and it is slated for removal from the S&P 500.
• The company announced a 15% companywide layoff following disappointing Q3 earnings and a lowered forecast.
• Nearly the entire C-suite has turned over in the past year.
