Why is Magnite, Inc. Common Stock (MGNI) stock moving?
Magnite reported a strong Q3 2026 on Nov 4: revenue of $204.2M and adjusted EPS of $0.33 beat estimates of $190.2M and $0.29, and Contribution ex-TAC rose 20% year over year above the top of guidance. The company raised FY2026 Contribution ex-TAC guidance to $783.4M from $756.6M-$763.3M and guided Q4 to $227M-$233M against a $219M estimate. The stock closed at $22.79 on Nov 4 and jumped 20.8% to $27.52 on Nov 5 on 9.7M shares, more than five times its late-October daily average of about 1.8M. It has since held in the $27-$29 range, closing at $28.52 on Nov 10 on volume of 2.8M, about 25% above the pre-earnings close. Analysts responded with a wave of target increases: Susquehanna $35, BTIG $33, Evercore $33, B. Riley $32, Scotiabank and RBC $30, StoneX $44, and Wells Fargo $23 with an Equal-Weight rating, so most listed targets now sit close to the current price. Recent partnerships with OpenAI (Nov 2, ChatGPT advertising) and Gracenote (Nov 10, CTV curation) add growth angles. The main limitation is that the evidence centers on one quarter and a rapid re-rating, so further upside depends on delivering the Q4 outlook.

About Magnite, Inc. Common Stock
Magnite is the largest independent sell-side advertising platform. It runs software that helps publishers and streaming services sell their ad space automatically to advertisers. It formed in 2020 when Rubicon Project merged with Telaria, then grew larger by buying SpotX and SpringServe, and today its strongest position is in connected TV (streaming) advertising.
How it makes money
Magnite earns fees, mostly a cut of the ad spending that passes through its platform, from publishers that use it to sell ad inventory through auctions and direct deals. As of Q3 2026, connected TV made up roughly half of contribution ex-TAC (approximately $105M of $201M, up about 39% year over year). The rest came from DV+, its desktop, mobile web and app business (approximately $95M, up about 5%). Total quarterly revenue was approximately $204M. Political advertising added an extra boost in 2026.
