The mobile ad network landscape changed permanently when AppLovin acquired ironSource. Two of the largest in-app monetization platforms — once fierce rivals in rewarded video, offerwall, and mediation — now sit under one corporate roof. For mobile game developers and publishers evaluating AppLovin vs ironSource in 2026, the question is no longer just which SDK performs better, but how the AppLovin ironSource merger reshapes pricing, competition, and choice across the entire ad-tech stack.

This guide is a complete mobile ad network comparison for 2026. We break down the merger, compare AppLovin MAX and ironSource LevelPlay, dig into the AppLovin SDK and ironSource SDK, and examine ad formats, eCPM, analytics, and mediation. We also explain where Perkox fits as a developer-first alternative for offerwall monetization.

1. The AppLovin–ironSource Merger: What Happened

AppLovin announced its intent to acquire ironSource in 2022 in an all-stock deal valued at roughly $4.2 billion at the time. The transaction closed later that year after shareholder and regulatory approvals, combining two of the most widely deployed mobile ad networks and mediation platforms into a single publicly traded entity. By 2026, the operational integration is mature: shared sales pipelines, consolidated demand sources, and increasingly unified product roadmaps.

What makes the AppLovin ironSource merger significant for publishers is the combination of complementary strengths. AppLovin brought a massive programmatic demand side (AppLovin Exchange), a fast-growing in-app bidding stack (MAX), and a large studio business. ironSource brought a dominant offerwall and rewarded video business, the LevelPlay mediation platform, and deep relationships with casual and mid-core game studios. Together, the combined company touches a huge share of monetizing mobile games.

Key facts about the merger:

• Deal structure: All-stock acquisition; ironSource shareholders received AppLovin shares.
• Strategic rationale: Combine AppLovin’s programmatic demand with ironSource’s mediation and offerwall expertise.
• Product continuity (2026): Both MAX and LevelPlay remain available, but back-end demand, analytics, and account management are increasingly shared.
• Competitive concern: Fewer independent mediation options means less negotiating leverage for mid-size publishers.

2. Platform Overview: AppLovin MAX vs ironSource LevelPlay

Although both platforms now belong to the same company, they remain distinct products with different heritages and optimization targets. Understanding the difference is essential to any honest mobile ad network comparison.

AppLovin MAX

MAX is AppLovin’s in-app bidding and mediation platform. It was built from the ground up around real-time bidding (RTB) and is tightly integrated with the AppLovin Exchange (ALX). MAX’s core value proposition is price competition: multiple demand sources bid simultaneously for each impression, and the highest bid wins. This model tends to favor publishers with strong programmatic demand and large impressions volumes.

ironSource LevelPlay

LevelPlay is ironSource’s mediation platform, built on a transparent auction model that predates the current in-app bidding wave. It has historically been strongest in offerwall and rewarded video, where ironSource’s owned-and-operated demand is deep. LevelPlay exposes granular reporting on each network’s performance and lets publishers weight networks manually or run automated auctions.

3. SDK and Integration Comparison

The AppLovin SDK and ironSource SDK are both mature, battle-tested, and widely deployed across millions of devices. Both ship as native iOS and Android SDKs with Unity and Unreal adapters, and both publish integration documentation and sample code. But there are meaningful differences in developer experience.

AppLovin SDK Integration

The AppLovin SDK is a single, unified package that includes the AppLovin network plus adapters for mediated networks. Integration typically involves adding the SDK via CocoaPods/Gradle, initializing with your SDK key, and configuring ad units. The MAX mediation layer uses auto-detected adapters, which reduces manual setup. AppLovin’s documentation is comprehensive and the SDK is well-regarded for stability.

Typical integration steps:

1. Add the AppLovin SDK dependency (CocoaPods, Gradle, or Unity package).
2. Initialize ALSdk with your SDK key at app launch.
3. Configure mediated network adapters via the MAX dashboard.
4. Implement ad load/show callbacks for each format.

ironSource SDK Integration

The ironSource SDK is modular and historically optimized for fast offerwall and rewarded video integration. Publishers often report that getting a basic offerwall live with ironSource takes less time than with competitors, because the offerwall format is ironSource’s heritage product. The LevelPlay mediation layer exposes per-network performance and allows fine-grained weighting.

Typical integration steps:

1. Add the ironSource SDK dependency.
2. Initialize IronSource with your app key.
3. Configure LevelPlay mediation networks in the dashboard.
4. Implement LevelPlayRewardedAd / offerwall delegates.

4. Ad Format Comparison: Rewarded Video, Offerwall, Interstitial

Ad format support is where the AppLovin vs ironSource comparison gets most concrete. Both platforms support the major monetization formats, but their relative strength varies.

Rewarded Video

Rewarded video is the cornerstone of mobile game monetization. Both AppLovin and ironSource have world-class rewarded video products with high fill rates and competitive eCPMs. AppLovin’s rewarded video is powered by ALX programmatic demand and tends to perform exceptionally well in regions with strong programmatic liquidity (North America, Western Europe). ironSource’s rewarded video benefits from its owned demand and is consistently strong in casual and hyper-casual genres globally.

Offerwall

The offerwall — a marketplace where users complete tasks (surveys, app installs, subscriptions) in exchange for in-game currency — is ironSource’s signature format. ironSource’s offerwall has long been the market leader in terms of inventory depth and revenue per user. AppLovin has built out its own offerwall capability, but the ironSource offerwall remains the more mature product. This is precisely the format where independent alternatives like Perkox compete most aggressively, since offerwall economics depend on inventory diversity and competitive revenue share rather than on programmatic bidding.

Interstitial

Both platforms offer full-screen interstitials with similar technical capabilities (timing controls, frequency caps, skip logic). Interstitial eCPM is largely a function of demand depth and geographic mix, and both platforms perform comparably. AppLovin’s interstitial demand benefits from ALX; ironSource’s interstitial demand benefits from cross-promotion across its owned casual game portfolio.

5. Revenue and eCPM Comparison

eCPM (effective cost per mille) is the metric publishers care about most, and it’s also the hardest to compare fairly because it depends on geography, genre, user quality, and ad placement. That said, industry data and publisher reports give us a clear directional picture for 2026.

Rewarded Video eCPM (2026 benchmarks)

• Tier 1 (US, UK, CA, AU): AppLovin $30–$60 eCPM; ironSource $28–$55 eCPM.
• Tier 2 (Western Europe, Japan, Korea): AppLovin $15–$35; ironSource $14–$33.
• Tier 3 (LATAM, SEA, MENA): AppLovin $3–$12; ironSource $3–$11.

These ranges overlap heavily. In practice, most publishers run both networks through mediation and let the auction pick the winner per impression.

Offerwall Revenue

Offerwall revenue is better measured as ARPU (average revenue per user) or revenue per offerwall-session, because eCPM is less meaningful for a format that pays per completed task. ironSource has historically led here, with offerwall ARPU often $0.15–$0.60 per active offerwall user in casual games, and higher in mid-core. AppLovin’s offerwall is growing but trails ironSource’s inventory depth in 2026. Independent offerwall providers like Perkox often match or exceed ironSource on revenue share because of lower platform overhead and a developer-first pricing model.

Interstitial eCPM

• Tier 1: AppLovin $10–$25; ironSource $9–$23.
• Tier 2: AppLovin $5–$14; ironSource $5–$13.
• Tier 3: AppLovin $1–$5; ironSource $1–$5.

6. Analytics and Reporting Comparison

Both platforms offer self-serve dashboards with real-time and next-day reporting, but the depth and transparency differ.

AppLovin MAX Dashboard

The MAX dashboard provides real-time revenue, impressions, eCPM, and fill rate broken down by app, ad unit, network, country, and ad format. It supports cohort-level analysis and integration with major MMPs (AppsFlyer, Adjust, Kochava). Its strength is clarity: the in-app bidding model makes it easy to see which network won each impression and at what price.

ironSource LevelPlay Dashboard

The LevelPlay dashboard exposes per-network performance, auction results, and offerwall-specific metrics (completions, payout per completion, fraud flags). It is particularly strong for offerwall analytics, where it surfaces task-level data that AppLovin’s dashboard historically aggregated more coarsely. LevelPlay also offers a “true eCPM” view that accounts for network-side fees.

7. Mediation Capabilities

Mediation is the layer that lets a publisher call multiple ad networks for a single impression and pick the highest-paying bid. It is the single most important architectural decision in mobile ad monetization, and it is exactly the area where the AppLovin–ironSource merger has the biggest competitive implications.

AppLovin MAX Mediation

MAX is a modern in-app bidding mediation platform. Every ad request goes to all configured networks simultaneously, and the highest bid wins. This is the cleanest model for publishers because it maximizes price competition without manual tuning. MAX supports 30+ mediated networks including AdMob, Meta Audience Network, Unity, Verve, and Liftoff. The downside: because AppLovin owns MAX, there is an inherent conflict of interest — AppLovin’s own demand competes in the same auction it operates.

ironSource LevelPlay Mediation

LevelPlay offers a hybrid model: automated auctions plus optional manual network weighting. This gives publishers more control over which networks are prioritized, which some mid-size publishers prefer. LevelPlay supports 20+ networks and is especially strong when offerwall is a significant revenue stream, because it integrates offerwall and rewarded video bidding in one flow.

Post-Merger Mediation Reality

Because AppLovin and ironSource are now one company, publishers who use both MAX and LevelPlay are effectively routing their mediation through a single vendor. This reduces redundancy but also reduces independent alternatives. The remaining major independent mediation options are Google AdMob, Unity LevelPlay (separate from ironSource LevelPlay despite the name confusion), and emerging platforms like Perkox for offerwall-specific mediation.

8. How the Merger Affects Developers and Publishers

The AppLovin ironSource merger has reshaped the economics of mobile ad monetization in several concrete ways:

Reduced Competition

Before the merger, publishers could play AppLovin and ironSource against each other in negotiation, demand, and revenue share. That independent competition is gone. Where publishers once benefited from two large players undercutting each other on take rates, they now face a single entity with consolidated leverage.

Converging eCPMs

As demand infrastructure is shared between MAX and LevelPlay, the eCPM gap between the two narrows. This is good for consistency but reduces the upside of running both networks in parallel — the incremental revenue from mediating both is smaller than it was pre-merger.

Account Consolidation

Publishers that previously had separate account managers at AppLovin and ironSource now typically work with a unified account team. For large publishers this can mean better support; for small and mid-size publishers it can mean less personalized attention and less negotiating room.

Offerwall Concentration Risk

Because ironSource’s offerwall is now owned by AppLovin, the offerwall market is more concentrated. Publishers that rely heavily on offerwall revenue face more platform risk. This is the single strongest argument for integrating an independent offerwall provider — to diversify away from a single vendor controlling both your mediation and your offerwall.

What Publishers Should Do in 2026

• Diversify mediation: Don’t rely solely on one company for both mediation and demand.
• Add an independent offerwall: Integrate a provider like Perkox alongside ironSource to preserve competition and revenue share.
• Audit revenue share: Post-merger, review your take rates and compare against independent alternatives.
• Monitor eCPM convergence: Track whether running both MAX and LevelPlay still yields incremental revenue.

9. Where Perkox Fits as an Alternative for Offerwall Monetization

Perkox is a developer-first offerwall SDK monetization platform built specifically to address the concentration risk created by the AppLovin–ironSource merger. Where the combined AppLovin/ironSource entity controls both mediation and offerwall demand, Perkox offers an independent, transparent offerwall that competes on inventory depth, revenue share, and developer experience.

Why publishers choose Perkox

• Independent demand: Perkox is not owned by a mediation platform, so there is no conflict of interest in the auction.
• Transparent eCPM and revenue share: Publishers see exactly what each offer pays and what share they keep.
• Fast SDK integration: The Perkox SDK is lightweight and designed for quick offerwall deployment on iOS, Android, and Unity.
• Competitive ARPU: Perkox aggregates high-quality offer inventory from multiple sources, often matching or beating ironSource on offerwall ARPU for casual and mid-core games.
• Developer-first roadmap: Perkox ships features based on publisher feedback, not on the needs of a parent company’s studio business.

How Perkox complements (not replaces) MAX and LevelPlay

Most publishers should not rip out AppLovin or ironSource — both are excellent at what they do. The smart 2026 stack is a hybrid: use MAX or LevelPlay as your primary mediation for rewarded video and interstitial, and integrate Perkox as a dedicated, independent offerwall demand source. This preserves competitive pressure on revenue share, diversifies offerwall inventory, and reduces single-vendor risk.

10. FAQ

Conclusion

The AppLovin vs ironSource comparison in 2026 is fundamentally different from the pre-merger era. The two platforms are now one company, their eCPMs are converging, and the competition that once benefited publishers has been internalized. For rewarded video and interstitial, the combined AppLovin/ironSource stack remains excellent. For offerwall, the concentration risk is real — and that is exactly where independent providers like Perkox add the most value.

The optimal 2026 monetization stack is a hybrid: a strong primary mediation platform (MAX or LevelPlay) for programmatic formats, plus an independent offerwall provider like Perkox to preserve competition, transparency, and revenue share. If you’re heavily reliant on ironSource’s offerwall today, the lowest-risk, highest-upside move is to add Perkox as a parallel demand source and let the numbers speak for themselves.
