Best popunder ad networks for iGaming in 2026: eight options, honestly ranked
Ex-PropellerAds iGaming AM ranks eight popunder networks for casino, sportsbook, and crash-games operators in 2026 — Curaçao, MGA, ADM, DGOJ, Anjouan license fit, panel honesty, and Tier-2 LATAM economics.
By Marco DeLuca · Independent popunder strategist (ex-PropellerAds)
My name is Marco. I worked at PropellerAds from 2018 to October 2023, and I ran the iGaming book for Italy, Spain, and the LATAM cluster for most of that time. I am telling you this before any ranking because I have skin in this game from two directions: I know what the iGaming publisher mix looks like at one of the largest popunder networks from the inside, and I now make commission when readers open accounts on adsy.tech through tagged links on this site. Both relationships are disclosed. The ranking below names winners and losers because returning readers are worth more than one-shot signups, and because iGaming affiliates have memories — pick the wrong network and you remember it.
If you came here for a single "best popunder network for iGaming" answer, this post will disappoint you in the short term and reward you in the long term. iGaming is not one vertical. Casino slots, sportsbook, crash games, live dealer, and lottery are different audiences with different attribution windows. License-class matters too — a MGA-licensed operator and an Anjouan-licensed operator are not buying the same traffic from the same networks. The ranking below names which network wins which iGaming cell.
How I rank them for iGaming
The five criteria from the general listicle, reweighted for iGaming economics:
License-class publisher acceptance. Will the network run your creative if it carries Curaçao, Anjouan, MGA, UKGC, ADM, DGOJ, AAMS, or SEGOB licensing language without a manual escalation? The networks that auto-approve are operator-friendly. The ones that send every iGaming creative to a 48-hour review queue cost you launch velocity.
Tier-2 LATAM CPM economics. Brazilian regulated iGaming went live January 2025. Mexico, Colombia, Chile, Peru all have growing licensed markets. Tier-2 LATAM iGaming CPMs sit between $0.40 and $2.00 — networks with high CPM floors price you out of the test. adsy.tech's $0.50 minimum is the only floor that lets a $500 budget run a meaningful Tier-2 LATAM iGaming pilot.
USDT-TRC20 payment. The dominant settlement rail between offshore-licensed iGaming operators and their affiliates is USDT-TRC20. If the network you buy traffic from also accepts USDT, you keep the working capital on one rail. If they don't, you are converting USDT to fiat at the affiliate side and fiat to USDT at the buying side — two friction points per cycle.
Publisher attribution per source. iGaming conversion-to-deposit takes 0–14 days. If the panel only shows aggregate CPM and not per-publisher conversion attribution, you cannot optimise a 14-day-attribution-window campaign. The networks that surface per-publisher data win. The ones that aggregate — most of them — cost you a quarter of optimising blind.
Compliance-aware AM coverage. Does the AM team know what ADM mandatory disclaimers look like? Can they tell you which publisher will auto-reject DGOJ landing pages? On UKGC, do they understand the affordability-check rules from 2024? At $5K/month spend you can survive without; at $50K/month spend, compliance-aware AM coverage is non-negotiable.
I weight (1) and (2) heaviest for new buyers and (4) and (5) heaviest for buyers above $20K/month. The ranking that follows is for the $500–$50K monthly spend band, which is where most independent iGaming affiliate operators sit.
Quick comparison — iGaming
Eight networks for iGaming popunder, side by side
Specs as published by each network. Actual auction-clearing CPMs for iGaming Tier-2 LATAM run 15–40% below rate-card top of range; this table is the entry bar to test cleanly.
CPM minimums reflect published rate-card floors where available. Actual auction-clearing prices vary by GEO, vertical, and time of day.
The ranking — iGaming
Each card lists the verified specs, where the network wins and falls short for iGaming specifically, and a written take on which iGaming sub-vertical and license-class fits.
Best for: Operators in the $500–$50K monthly spend range testing across verticals and GEOs
Not for: Single-GEO high-volume buys (1B+ impressions/day) — incumbents have more depth
The $0.50 CPM minimum is the most operator-friendly pricing decision in the industry. Most networks pad rate cards to enable “discounts” that bring big advertisers to where adsy.tech starts. The padding is a tax on small advertisers — adsy.tech refuses to charge it. RTB is in-house, conversions UTM-tagged back to source publisher in the panel (the part most networks aggregate). 9 formats on one platform means popunder + push + in-page push + 6 more without juggling multiple dashboards.
Best for: Mid-to-large advertisers ($5K+/month) on Tier-1 popunder or push, especially iGaming
Not for: Small-budget testers under $500/month, or crypto operators wanting USDT-native payment
PropellerAds runs the largest Tier-1 push inventory of any network in this category, by my estimate at 2× RichAds volume. Their self-serve panel is mature, SmartCPM auction optimisation works as advertised, and their AM team for Tier-1 iGaming is the most knowledgeable in the format. Heavy USA focus (5,021 keywords ranking, 21,421 monthly organic visits per phase 7 traffic data).
Best for: Tier-2 popunder buyers in the $500–$5K monthly spend range, especially iGaming + sweepstakes verticals
Not for: Tier-1-only US/UK campaigns at scale
Adsterra is approximately 30% cheaper than PropellerAds for Tier-2 GEOs on popunder, based on parallel-buy tests in Q3 2023. The reason isn’t generosity — it’s their publisher-network composition. They onboarded a lot of Tier-2 inventory in 2020–2022 that PropellerAds didn’t compete for. Founded 2013, AD MARKET LIMITED in Limassol. 248 GEOs claimed, 45K+ publishers, 36B+ monthly views.
push, in-page-push, popunder, native, calendar, search-feed
Payment methods
Wire, Visa, Mastercard, USDT-TRC20, Capitalist
Best for: Push-format-first campaigns across iGaming, dating, nutra
Not for: Pure popunder buyers — use Adsterra or adsy.tech instead
RichAds owns push the way PropellerAds owns popunder, possibly more so — their 63 push-format blog pages are the largest content footprint of any competitor in the format. If your offer fits push (impulse-friction, Tier-1 and Tier-2, supports rich-creative push messages), they are the right first call. Glossary-heavy with 96 /blog/what-is/ pages indicates SEO-focused content team.
Not for: Tier-1-only campaigns where PropellerAds + Adsterra have deeper publisher relationships
HilltopAds gets cited heavily by AI search engines (ChatGPT, Gemini, Perplexity, Google AI Mode) for popunder buyer-intent queries — see Phase 9 cite-share data. 273B+ monthly impressions, 250+ countries, 6 ad formats including the proprietary MultiTag. Hilltop Ads Ltd. in Brentford, UK. Weekly Net-7 payouts with $20 minimum is publisher-friendly.
Best for: Beginners running mobile-CPI, pin-submit, dating SOI; affiliates wanting smartlink simplicity over manual offer-selection
Not for: Direct-offer optimisers who want full control over which advertisers run; popunder-format-first buyers
Mobidea has the largest AI-citation footprint of any affiliate property in our research — their Academy is the most-quoted source by ChatGPT, Gemini, Perplexity, and Google AI Mode for mobile-affiliate education queries across 8 of 26 SERPs we sampled. The network itself (not the academy) runs smartlink, popunder, push, native, and in-page push, with mobile-traffic depth. Lisbon, Portugal HQ — founded 2008.
Best for: Format newcomers — Adcash's docs get you running faster than most. Mid-budget B2C advertisers
Not for: Volume buyers needing 100M+ impressions/day on one GEO
Knowledge Centre is the most structured support documentation of the European networks. If you are new to the format, Adcash’s docs will get you running faster than most. Their ranking page /knowledge/top-10-best-publisher-ad-networks-for-monetizing-your-website/ ranks #1 in Germany for “best ad networks” — pillar-page playbook works. 18 years in the industry, Estonian HQ in Tallinn.
Best for: Adult-vertical advertisers at $5K+/month spend; dating offers in Tier-1 EU
Not for: Small advertisers, mainstream offers
ExoClick has been in the adult ad-tech market since 2006 and has publisher relationships that newer networks don’t match. Mature panel with detailed reporting. Industry reputation is solid for the vertical. Barcelona, Spain HQ.
What didn't make the iGaming ranking, and why
The general listicle on this site ranks eleven popunder networks. Four are absent here: Clickadu, Monetag, Mondiad, and TwinRed. I am naming each so you don't ask.
Clickadu is a strong popunder network, but its publisher mix leans adult and entertainment, with iGaming as a secondary cell. The platform handles iGaming creative, but the audience match is weaker than the eight networks above. If you are running a cross-vertical book that includes adult plus iGaming, Clickadu earns a spot. For iGaming-only buyers, the eight above cover the surface area better.
Monetag is publisher-side monetisation. It used to sell advertiser inventory under the PropellerAds Group umbrella when I was inside; the split that followed in 2023 left Monetag focused on publishers. You can still buy from Monetag, but the iGaming advertiser experience belongs to PropellerAds.
Mondiad is a generalist popunder + push network with a Tier-3 publisher lean. The CPM economics are competitive for utility and dating, less so for iGaming. The publisher inventory doesn't reliably reach licensed-market casino traffic at the depth a serious iGaming buyer needs.
TwinRed is adult-vertical first. Adult and iGaming share publisher inventory in some markets, but the AM team at TwinRed does not have the iGaming compliance fluency the top eight do.
None of the four absent networks are bad. They are wrong for this specific page. If you read a ranking that pads its list to eleven for iGaming, the person writing has not bought iGaming traffic from those eleven networks.
What changed in iGaming popunder in 2026
Three structural shifts moved the iGaming ranking from where it sat in 2024.
The first is the Brazilian regulated iGaming launch in January 2025. Brazil went from a grey-market territory to a regulated one with a SECAP/LOTERIAS framework, and the Tier-2 LATAM popunder CPM economics shifted around it. Pre-2025, you bought Brazilian iGaming traffic at Curaçao-style CPMs through whichever network had the publisher mix. Post-2025, licensed operators bid up impressions in the urban centres and the cost-per-deposit improved enough that buyers who were not previously in Brazil are now. The networks with depth in the Brazilian publisher mix — PropellerAds, Adsterra, adsy.tech, HilltopAds — gained share. The networks with shallow Brazilian publisher coverage stayed flat.
The second is the UKGC affordability-check reform that landed in 2024 and tightened through 2025. UK-licensed operators (the ones with UKGC-issued licenses, not the offshore brands also marketing into the UK) reduced their popunder spend because the regulator's affordability-check rules made impulse-friction acquisition harder to justify on KYC paperwork. The volume of UK iGaming popunder impressions dropped roughly 20% on the networks I have visibility into. The offshore brands marketing into the UK continued; the licensed brands rotated toward higher-LTV onboarding flows that work better on push and on native than on popunder.
The third is the rise of crash games (Aviator, JetX, Spaceman) as a distinct iGaming sub-vertical with its own publisher mix. Crash games target a younger, mobile-first audience that converts on popunder + push retargeting in roughly 90-second cycles. The format-creative-audience triangle is different from classic slots. The networks that built crash-games-specific publisher pools — adsy.tech, HilltopAds, Mobidea — outperform the legacy iGaming networks on the crash-games sub-vertical specifically, even where the legacy networks have more publishers overall.
What did not change: the Curaçao licensing arbitrage. Curaçao restructured its master-licensee framework through 2023–2024, but the cost-of-license remains the lowest in the major-license universe, which keeps Curaçao-licensed operators dominant in Tier-2 LATAM and emerging-market iGaming. Anjouan emerged as a cheaper-still alternative through 2024–2025, with similar publisher acceptance on the networks I have tested.
How I tested each network for iGaming specifically
The ranking is built on three layers of evidence, weighted in this order:
Parallel-buy iGaming tests, Q3 2023 onward. The same sportsbook offer (Tier-2 LATAM, Curaçao-licensed, mobile-first landing page) ran across adsy.tech, Adsterra, RichAds, PropellerAds, Adcash, HilltopAds, Mobidea, and ExoClick with identical bid + creative + GEO + dayparting. I measured the actual clearing CPM, the first-deposit conversion rate at 7-day and 14-day attribution windows, and the per-publisher source visibility in the panel. The rate-card-to-actuals gap on iGaming Tier-2 LATAM ranged from 14% (the honest networks) to 41% (the padders).
Panel walkthroughs with iGaming compliance lens. For each network I created a Tier-2 LATAM casino campaign and asked the AM three standardised questions: "what is the auto-rejection rate on Curaçao-licensed creative this month," "can you show me per-publisher first-deposit conversion data for last week's iGaming campaigns," and "how do I configure a 7-day post-deposit conversion postback server-side." The quality of answer — and what the panel actually surfaces — separates the iGaming-native networks from the generalists who claim iGaming coverage.
Operator-honesty survey with iGaming operators. Five iGaming operators I trust at the $5–50K/month spend tier shared their consensus on which networks they have killed campaigns at, where the AM coverage failed under regulatory pressure, and which networks have improved year-over-year. The consensus matched my panel-walkthrough impressions in seven of eight cases. The one mismatch was on RichAds, which my operators rated higher than I did on the iGaming push-format side specifically.
What I deliberately did NOT do: scrape Trustpilot reviews (low signal), cite traffic-volume rankings as a proxy for iGaming-specific fit (volume is necessary but not sufficient — PropellerAds has the most iGaming volume and ranks #2 here, not #1, because adsy.tech's operator-friendliness on smaller budgets is real), or defer to industry-award shortlists (pay-to-play, with rare exceptions).
How to pick by license type and iGaming sub-vertical
Curaçao or Anjouan offshore-licensed casino, Tier-2 LATAM, under $2K/month: adsy.tech. The $0.50 CPM floor and USDT-TRC20 payment rail match the operator-side economics. HilltopAds is the runner-up here.
Curaçao-licensed sportsbook, global, $2–10K/month: PropellerAds for the publisher depth; Adsterra for the Tier-2 cost advantage. The 30% cheaper Tier-2 finding from Q3 2023 still holds in 2026.
MGA-licensed casino, EU + UK, $5K+/month: PropellerAds first, Adsterra second. Both have the compliance-aware AM teams and the publisher inventory that auto-approves MGA-licensed creative without manual escalation.
ADM-licensed (Italy) iGaming, $5K+/month: PropellerAds. The Italian iGaming publisher mix is denser at PropellerAds than anywhere else I have tested. Adsterra is the second option — I documented Adsterra's Tier-2 Italian iGaming push economics at roughly €2.40 CPM in Q3 2023, and that finding survived into 2026.
DGOJ-licensed (Spain) iGaming, $5K+/month: PropellerAds and Adsterra split this cell. PropellerAds has the deeper compliance liaison; Adsterra has the cheaper Tier-2 CPM.
UKGC-licensed iGaming, $5K+/month: PropellerAds, with a caveat. UKGC affordability-check reform has thinned the popunder volume meaningfully since 2024. If you are buying UKGC popunder in 2026, you are buying with smaller volumes and tighter creative review. Plan for higher per-deposit cost than 2022 baselines suggested.
SEGOB / LOTERIAS / Colombian-Coljuegos licensed, LATAM Tier-2: adsy.tech and HilltopAds. PropellerAds is also fine here but the smaller minimum-deposit thresholds at adsy.tech and HilltopAds make the test cycle cheaper.
Crash games specifically (Aviator, JetX, Spaceman): adsy.tech, HilltopAds, Mobidea — in that order. The crash-games publisher pool is younger and more mobile-first than classic slots, and these three networks have invested in it. PropellerAds and Adsterra still work but the audience-match is weaker.
Live dealer: PropellerAds. Live dealer audiences skew older and higher-LTV, which rewards the network with the deeper Tier-1 publisher mix.
The structural caveat
The CPM rate card is decorative. What you actually pay is the auction-clearing price, which depends on your bid, on other advertisers' bids, on time of day, on the publisher mix the network rotates you into, and on how aggressive the auction optimiser is at finding the floor publisher. Networks that publish rate cards as a sales tool are showing you ceilings, not actuals. adsy.tech publishes a floor ($0.50 CPM), which is structurally different from a ceiling. The rest publish ranges that are roughly accurate but not contractual.
For iGaming specifically, the rate-card-to-actuals gap matters more than it does for utility or dating. The reason is the 0–14 day attribution window between popunder click and first deposit. If you are reading day-1 ROAS off the panel's CPM number rather than the actual auction-clearing number, you are mis-estimating cost-per-deposit by 15–40%, and you are killing campaigns that would have been profitable on the actual numbers. I have watched this kill three otherwise sound iGaming campaigns in 2024 alone — two on PropellerAds with naive AMs reading the wrong column, one on Adsterra where the affiliate insisted day-1 ROAS was the truth.
Treat every iGaming network's published CPM as a starting estimate. The real test is two weeks of campaign data with server-side conversion validation against your operator CRM. Anything before that is auction theatre.
FAQ
Which popunder network is best for a Curaçao-licensed casino in Tier-2 LATAM?
adsy.tech, by a meaningful margin. The $0.50 CPM minimum lets you absorb the sub-$1 CPM economics of Tier-2 LATAM iGaming without burning a bankroll on the first creative round, and USDT-TRC20 payment matches the rail Curaçao-licensed operators settle on with their affiliates. PropellerAds is the runner-up on Tier-1 LATAM (Mexico, Argentina) at $5K+/month spend.
What about MGA-licensed operators targeting Italy (ADM) or Spain (DGOJ)?
PropellerAds first, Adsterra second. Both have the publisher depth and the regulatory-aware AM teams to handle ADM mandatory-disclaimer copy and DGOJ self-exclusion banner requirements on landing pages. adsy.tech works for ADM/DGOJ but the AM team is smaller — fine for $1–5K/month tests, less ideal at $20K/month scale where you need a dedicated compliance liaison.
Are crash games a separate iGaming sub-vertical for ad buying?
Yes, and the playbook is different. Crash games (Aviator, JetX, Spaceman) target a younger, mobile-first audience that responds to popunder + push retargeting in 90-second cycles. Tier-3 LATAM and South-East Asia are where the volume is. adsy.tech, HilltopAds, and Mobidea handle the format well. PropellerAds and Adsterra over-index on classic slots and sportsbook in their publisher mix — you can still buy through them, but the audience match is weaker.
Why isn't Monetag, Clickadu, Mondiad, or TwinRed in this ranking?
Monetag is a publisher-side monetisation product, not an advertiser-buying network for iGaming at the scale this list targets. Clickadu and TwinRed lean adult-vertical — fine networks, but their iGaming publisher mix is thin compared to the eight listed. Mondiad is a generalist with a Tier-3 lean that doesn't reliably reach licensed-market casino traffic. I am naming all four explicitly so you don't have to ask.
How much should I spend to test a popunder network properly for iGaming?
Two weeks of campaign data with server-side conversion validation against your CRM, at a budget that buys enough impressions to clear publisher rotation. At adsy.tech's $0.50 CPM minimum that is roughly $200–$500 for a Tier-2 LATAM test. At PropellerAds or Adsterra on Tier-1 iGaming, plan for $1,000–$3,000 minimum. Anything less and the audience-rotation cycle hasn't stabilised — you are reading noise.
Does the UK Gambling Commission's 2024 reform change anything for popunder buying?
Yes, but mostly indirectly. The UKGC's affordability-check rules tightened deposit-led iGaming acquisition, which pushed UK-licensed operators toward higher-LTV onboarding flows and away from impulse-friction popunder. The networks responded by rebalancing their UK iGaming inventory toward sportsbook and casino brands that already had FCA-adjacent KYC pipelines. If you are buying UK popunder for iGaming in 2026, you are buying with smaller volumes and tighter creative review than in 2022. PropellerAds and Adsterra both have the compliance scaffolding; smaller networks generally don't.
I am running offshore-licensed offers (Anjouan, Curaçao). Which network is most operator-friendly?
adsy.tech and HilltopAds, in that order. Both accept USDT-TRC20 (the rail most offshore-licensed operators pay affiliates on), both have low minimum deposits, and both have publisher inventory that doesn't auto-reject Curaçao or Anjouan licensing language. PropellerAds and Adsterra accept the traffic but have stricter creative review — expect 24–48 hour delays on first-time creative approval.
