Screencore SSP launch targets CTV and mobile with AI yield optimization

The introduction of this platform provides publishers with a direct route to 5,000 advertisers while reducing reliance on opaque intermediaries. By integrating AI-powered yield optimization with transparent auction mechanics, Screencore is positioning itself to capture spend from buyers prioritizing supply path optimization and privacy-first infrastructure. This move reflects a broader industry shift where streaming and mobile publishers require more granular control over impression value to maintain margins. As the programmatic ecosystem matures, the success of this rollout will be measured by its ability to sustain high fill rates across diverse global markets. Watch for Screencore to report specific eCPM lift metrics as more CTV publishers adopt their Prebid and SDK integrations.

Screencore's new SSP arrives in a sell-side landscape dominated by established players that are aggressively expanding their CTV and mobile capabilities. Magnite, the largest independent sell-side advertising company, reported Q1 2026 results showing CTV contribution ex-TAC of $82.3 million, up 30% year-over-year and now representing 51% of total contribution ex-TAC, a milestone that underscores how quickly programmatic CTV spend is consolidating around proven platforms. For a new entrant like Screencore, competing for publisher attention means demonstrating measurable yield improvements against incumbents that already process billions of monthly transactions across CTV, online video, display, and audio formats. On the business and competitive front, Magnite has been investing in AI-driven buyer-side tooling to deepen its moat. In late April 2026, Magnite expanded its AI buyer agent and SpringServe mediation tools, with Disney Advertising, MiQ, Kepler, and Spectrum Reach among the first testers. That move signals that incumbent SSPs are not standing still on the transparency and automation features that Screencore is positioning as differentiators. Meanwhile, eMarketer noted that CTV and in-app mobile advertising outpaced Magnite's broader revenue growth in Q1, with mobile revenues reaching $55.3 million, up 34% year-over-year, confirming that both channels Screencore targets are experiencing strong demand growth that could support new supply-path entrants. From a technical and market-structure perspective, the shift toward programmatic CTV revenue loss continues to reshape how publishers evaluate SSP partners. Magnite's Q1 2026 results showed net income of $4.4 million, reversing a $9.6 million net loss from the same period in 2025, alongside Adjusted EBITDA of $42.9 million, up 16% year-over-year, demonstrating that scale and operational efficiency remain critical in the sell-side business. Screencore's emphasis on transparent auction mechanics and AI-powered yield optimization will need to produce comparable unit economics for publishers before it can meaningfully shift budget allocation away from entrenched platforms that already offer global reach and multi-format support.
