Ad Tech Public Markets Face Structural Liquidity Crunch
Investment bankers argue that small market capitalizations, rather than operational failures, are driving the exodus of ad tech firms from public exchanges.
Public ad technology stocks are suffering from a structural liquidity deficit rather than fundamental business decline, according to industry bankers. Josh Wepman, managing director at Houlihan Lokey, stated that companies with market caps near $7 billion struggle to attract meaningful volume from index funds and mutual investors. This lack of organic buying pressure results in depressed valuations and declining multiples through 2025 and into 2026.
The sector is experiencing a consolidation trend where fewer, larger transactions account for the majority of deal value. Wepman noted that while total deal activity reached approximately $14 billion this year, the average transaction size has increased significantly. This dynamic pushes many mid-tier firms toward take-private offers, as they fail to meet the size thresholds required for stable public market participation.
Volatility Obscures Fundamental Valuation Signals
Nick Macshane, senior managing director at Progress Partners, highlighted the erratic pricing behavior of listed ad tech assets. He described a scenario where stocks that dropped 60% in one period rebounded by the same margin in the next, while high-performing assets subsequently crashed. This whipsaw effect creates a perception of randomness that deters long-term institutional capital from entering the space.
The Trade Desk serves as a primary example of these pressures. The company’s stock has fallen more than 80% since mid-2025 due to slowing growth and intensified competition. Consequently, the firm is scheduled for removal from the S&P 500 later this month, illustrating the difficulty of maintaining a large-cap public profile in this specific sector.
Corporate Acquirers Target Distressed Valuations
Despite the public market struggles, corporate interest in private acquisitions remains strong. Criteo is reportedly exploring a take-private deal, following similar moves by Doubleverify, LiveRamp, and Integral Ad Science. These transactions allow acquirers to secure strategic assets trading at a fraction of their historical peaks, bypassing the volatility of public listings.
New Entrants Expand Competitive Landscape
The competitive threat is no longer limited to traditional media consolidators. Enterprise software giants such as Salesforce, Adobe, ServiceNow, and Workday are actively pursuing targets. Additionally, data and AI firms like Databricks, Snowflake, and OpenAI represent a new class of acquirers. Their entry increases the premium placed on proprietary data assets, further incentivizing private ownership over public trading.
