Social Media Ad Spend Projected to Hit $640 Billion by 2030, Omdia Says

Why It Matters

The projection of $640 billion in social‑media ad spend signals a decisive shift in where marketers allocate budgets, emphasizing the need for video‑first creative and AI‑enhanced targeting. As a handful of platforms capture the lion’s share, advertisers must navigate a market where data access and algorithmic advantage are tightly controlled, potentially limiting innovation from smaller players. At the same time, the rise of self‑serve tools lowers entry barriers, enabling brands of all sizes to tap into high‑impact inventory, but also intensifying competition for user attention. Regulators are watching the concentration of ad dollars and the use of personal data for targeting. Any policy changes could reshape the economics of social advertising, making the projected growth a focal point for both industry strategy and public debate.

Key Takeaways

• Omdia forecasts global social‑media ad revenue to reach $640 bn by 2030.
• The sector is expected to grow at a 12% CAGR over the next five years.
• Social’s share of total online advertising will rise from 33% to 44% by 2030.
• Video formats accounted for 60% of social ad revenue in 2025.
• Six platforms generate roughly 90% of global social‑media ad spend.

Pulse Analysis

The $640 billion projection marks a watershed moment for digital marketers, confirming that social media has moved from a peripheral channel to the core of most advertising strategies. Historically, display and search dominated online spend, but the rapid adoption of short‑form video and the integration of shopping experiences have accelerated social’s ascent. This mirrors the earlier shift to mobile, where advertisers reallocated budgets to capture users on the go; today, the shift is driven by the convergence of content consumption and commerce within the same app.

AI’s role cannot be overstated. The Omdia report highlights that sophisticated recommendation engines give incumbents a moat that smaller platforms cannot easily breach. This creates a two‑tier ecosystem: the ‘walled gardens’ that command premium inventory and data, and the peripheral players that must rely on niche audiences or alternative formats. Brands that can harness the AI tools offered by the dominant platforms—while maintaining creative relevance—will likely capture the bulk of the projected growth.

However, concentration also breeds risk. Over‑reliance on a few platforms makes advertisers vulnerable to policy shifts, algorithm changes, or user backlash against ad overload. The warning about feed saturation suggests that the next inflection point may be user fatigue, prompting a potential pivot toward more organic, influencer‑driven, or community‑based tactics. Marketers should therefore diversify spend, experiment with emerging formats like AR ads, and build first‑party data strategies to mitigate platform dependency as the market matures.
