What Q2 Earnings Reveal About Ad Dollars, AI Costs and Ad Tech Deals
The latest quarterly earnings from the biggest ad-funded platforms showed another wave of strong revenue growth, but the reception was far warmer on Madison Avenue than on Wall Street. Meta generated $61 billion in Q2 revenue, up 28% year over year. Amazon grew at a similar 26% clip, with ad revenue approaching $20 billion. Google still leads on scale, with advertising revenue of $81.6 billion, but its growth rate of 14.5% trailed both rivals, and investors focused less on the growth than on the AI-related capital expenditure behind it.
Google also signaled a rare concession to advertiser concerns: a limited pilot for Performance Max campaigns that lets media buyers opt out of third-party search partners and the Google Display Network. The feature is small, but it follows years of complaints about the AI-powered product's brand safety risks and lack of control.
Independent ad tech companies now enter their own reporting window, with AppLovin, Criteo, Magnite and Taboola due to report on Aug. 5, PubMatic and The Trade Desk on Aug. 6, and Viant Technology on Aug. 10. That earnings calendar arrives against a backdrop of take-private speculation, including reports that Criteo could be the next candidate. The recent path is already clear: Integral Ad Science was taken private by Novacap, and LiveRamp agreed to be acquired by Publicis Groupe.
Deal activity, however, is not uniformly strong. LUMA Partners reports that overall ad tech deal volume fell 16% year over year in Q2, despite headline transactions such as Comcast's more than $1 billion acquisition of Vibe.co. The firm expects M&A to accelerate in the second half of 2026, with buyers focused on AI capabilities and connected TV.
Why Wall Street and Madison Avenue Are Reading the Same Numbers Differently
Why Wall Street Is Demanding More Than Ad Growth
Meta's 28% revenue growth and Amazon's 26% growth would normally be celebrated, but the market's focus has shifted to AI spending that is growing faster than operating cash flow, as I/O Fund analyst Beth Kindig noted. Google's 14.5% ad growth is respectable, yet it underscores how quickly Amazon and Meta are closing the gap from smaller bases. The tension is structural: agencies see rising ad spend; investors see unproven AI investments that could compress margins for years.
Google's PMax Pilot Is a Small Concession With a Large Subtext
The new Performance Max opt-out pilot is not a strategic overhaul, but it matters because Google rarely yields control over automated inventory. Buyers have spent four years complaining that PMax is a black box, and earlier brand safety studies showed the liabilities of letting AI decide where ads run. The pilot gives sophisticated buyers a mechanism to test whether the platform performs better when it cannot default to third-party search partners and the Google Display Network. If the pilot shows better outcomes, it will raise questions about why the controls were not offered sooner.
Private Equity Is Finding Value the Public Market Won't
IAS's completed sale to Novacap, LiveRamp's sale to Publicis and speculation around Criteo point to a common pattern: private buyers are willing to pay for stability and cash flow while public investors remain skeptical of independent ad tech's growth prospects. SI Global's study of more than 80 private equity firms and 266 portfolio companies adds a crucial caveat: AI is now viewed as a value-creation opportunity only when management has a credible plan to embed it into the commercial model. That means ad tech companies with vague AI stories will not attract take-private premiums, while companies with demonstrable AI-driven economics could.
OpenAI's Ad Ambition Still Needs a Persuasive Business Case
OpenAI's effort to build a $100 billion ad business by the end of the decade is real, and its promotional credits of $50 or $100 in matching incentives borrow a proven playbook from TikTok, Google and Meta. But the underlying skepticism has not gone away. Media buyers remain concerned about ROAS measurement, platform accessibility and high minimum spend requirements, and eMarketer expects OpenAI to fall well short of its stated target. Promotional credits create habit formation, but they do not by themselves solve measurement, and that gap is precisely where independent ad tech firms can still compete.
The Calendar That Could Reset the Story
The Aug. 5-10 earnings releases from AppLovin, Criteo, Magnite, Taboola, PubMatic, The Trade Desk and Viant will test whether independent ad tech can grow while Big Tech dominates. The results will also be read through a deal lens: any company that misses on guidance could quickly become another take-private candidate, especially with private equity convinced that public markets are undervaluing the sector.
What the August Earnings Window and Deal Chatter Mean for Ad Tech Players
The immediate decisions belong to investors, ad tech executives and media buyers, and the next two weeks create specific pressure points.
- Investors should treat the Aug. 5-10 earnings releases as a test of whether ad tech names can defend margins while investing in AI, given that Google, Meta and Amazon are combining scale with 14-28% ad growth.
- Media buyers should test Google's PMax opt-out pilot on real campaigns and record any differences in brand safety, transparency and performance, since the pilot currently excludes third-party search partners and the Google Display Network.
- Ad tech executives weighing a sale should note that SI Global's survey of more than 80 PE firms and 266 portfolio companies makes credible AI integration a condition for value-creation investment, not a nice-to-have.
- Strategic acquirers should take Zeta Global's new $1 billion M&A credit facility as a sign that well-capitalized buyers are preparing to compete for AI and CTV assets in a market LUMA expects to accelerate in the second half of 2026.
- Agencies negotiating principal media deals should put explicit price tags on AI infrastructure costs now, since holding companies are absorbing those costs in exchange for committed principal inventory and Omnicom's CEO has already acknowledged that nobody has actually priced AI yet.
Risk & Opportunity Assessment
| Commercial Risk | Medium | Big Tech is capturing most incremental ad spend, with Meta up 28% and Amazon up 26%, while LUMA reports ad tech deal activity down 16% year over year in Q2, leaving independent ad tech to prove growth under tougher conditions. |
| Competitive Risk | High | Google, Meta and Amazon are embedding AI into their ad platforms, Google's PMax controls inventory allocation, and OpenAI is building a rival ad business, all of which pressure independent ad tech companies' share of budgets. |
| Regulatory Risk | Low | The story does not cite new regulatory action; the main perimeter is brand safety concerns around AI-powered buying platforms, which are commercial and reputational rather than regulatory in this account. |
| Reputation Risk | Medium | Google's limited PMax pilot is a response to years of brand safety criticism, and media buyers remain skeptical of OpenAI's ROAS, measurement and minimum spend requirements, threatening trust in AI-led ad buying. |
| Technology Disruption | High | AI capex is dominating Big Tech strategy and outpacing operating cash flow, OpenAI is targeting a $100 billion ad business, and PE firms are making credible AI integration a condition for investment, making AI capability a core valuation factor. |
| Commercial Opportunity | High | Private equity remains willing to take ad tech public companies private where public markets are skeptical, LUMA expects M&A to accelerate in H2 2026 around AI and CTV, and Zeta Global has raised a $1 billion facility to fund inorganic growth. |
