1) We are short AppLovin $APP, an AdTech platform for mobile games. Having peaked at $173 billion in market cap, we believe AppLovin could go down as the single largest stock promotion unraveling since at least the GFC. Our full report is now available on our website, culperresearch.com
2) $APP shares are up ~25x in the past 2 years on $APP's promotion of supposed breakthrough AI tech, "AXON 2.0." $APP describes AXON 2.0 as a "black box" and investors seem content with this. We believe it's a smokescreen, and $APP's true secret sauce is far more nefarious.
3) In its mobile gaming business, we believe $APP has systematically deployed, then exploited incredibly dangerous app permissions that enable in-app ads themselves to force-feed silent, backdoor app installations directly onto users' phones, with just a single click. Image
Image
4) Given $APP's notorious UX gimmicks i.e., multiple "X" outs and fake countdowns, many clicks are inadvertent. Yet they potentially instantly trigger downloads anyway. $APP's entire business centers on app installs: this is AdTech's version of "rolling the truck down the hill." Image
Image
Image
5) Our report documents the full step-by-step process by which $APP has smuggled these "direct download" permissions into not only its own games, but thousands of highly popular games including Subway Surfers, 8 Ball Pool, Wordscapes, and Angry Birds. Image
6) We consulted renowned ad fraud researcher Dr. Ben Edelman to ensure our correct understanding of the abilities and functioning. He confirmed, adding that $APP also integrated the ability to "flip the switch" based on e.g., users IP address, location, activity - at its whim.
7) We believe these installations happen at unprecedented scale. $APP's own employees brag publicly of their ability to initiate "direct downloads for instant access to games from ads" and refer to "the ad product for Direct Download" as "the company’s top revenue driver.” Image
Image
8a) We provide a case study: "Animal Restaurant" (10M+ downloads) -- (a) users complain the app is automatically downloading other games, namely "Bricks n Balls" which is/was owned by $APP's own studio (b) Bricks n Balls reviews then allege that it too downloads without consent. Image
Image
8b) 3P download data for Bricks n Balls shows two highly irregular download spikes in Android, in May and Sept 2023, in Brazil and India respectively. This was just as $APP signed two new OEM partners - a precondition to the illicit download behavior - in those exact regions. Image

1) We are short AppLovin $APP - Ties to CCP Intelligence, Human Trafficking, Money Laundering; Undisclosed Stock Pledges; Secret Chinese e-Commerce Deals - all as the Company bids for TikTok. Our full report is now available at culperresearch.com
2) Since our initial February 2025 report, $APP has announced its desire to merge with TikTok ex-China. It cites "national security" and "data security" and CEO Foroughi claims the Company has no material Chinese investors and no Chinese ecom operations. Wrong on both counts.
3) Since 2017, $APP has been backed by Chinese national Hao Tang. We think $APP's disclosures violate SEC reporting rules - Tang appears to have controlled 28% of Class A shares ahead of $APP's 2021 IPO via offshore shells and at least 9.8% today. Image

NEW: We are short Archer Aviation $ACHR - and we're extending a $1 million wager to @jimmyfallon, who has earned millions to promote $ACHR. Jimmy - if you truly believe in Archer, prove it. Our offer, and our full report now available at culperresearch.comImage
Image
@jimmyfallon 2) We believe $ACHR has systematically lied about Midnight's progress in the LTM, to conceal underlying aircraft stability issues and its sham transition flight. Archer’s claim to near-term commercialization is not only premature, but reckless. Don't just take our word for it...
@jimmyfallon 3) On Feb 27, 2025, $ACHR claimed Midnight was "fully assembled" and "finishing up ground tests." Yet $ACHR emails we obtained via public requests reveal $ACHR's test flight crew didn't even have Midnight "in their hands" until March. Tough to do ground tests without an aircraft. Image

1) We are short Gorilla Technology Inc $GRRR - the most ridiculous fraud we’ve written about: fake products, fabricated deals, fraudulent partners, fictitious offices, and phony financials. We think $GRRR should be halted and delisted. Full report now at culperresearch.com
2) $GRRR claims to be a “leading edge AI company." It was incorporated in 2001 in the Cayman's infamous Ugland House - what Obama called “the biggest tax scam in the world.” Its global HQ is a temporary office above a London hair salon. Image
3) $GRRR claims to have become a "dominant" provider of what it claims is "AI hardware." It's website, however, shows this consists of washed up Dell desktop PCs and cameras widely available online for a few hundred dollars. $GRRR tossed its own logo on and calls it proprietary. Image

NEW: We are short Applied Optoelectronics $AAOI, a manufacturer of optical transceivers and components for data centers and cable television. Our full report is now available on our website. culperresearch.com
2) We think $AAOI misrepresents the status of supposedly ongoing 800G qualifications, overstates its production abilities, and has already squandered chances with multiple potential customers. $AAOI's calls to $500M+ in 800G revenues and current "ramping" are total fantasy.
3) Our research includes 20+ calls with former employees, competitors, and customers, as well as visits to $AAOI's facilities. We think today's setup mirrors the 2017 100G cycle, when $AAOI hid production problems and customer losses, insiders sold stock, and shares fell >90%. Image

1) We are short LendingTree $TREE, a highly levered internet lead gen company that we believe has failed to properly disclose two existential risks to its business. Our full report is now available on our website. culperresearch.com
2) First, LendingTree $TREE is sitting on a time bomb of class action litigation carrying a minimum of $157 million up to $472 million in damages - 82% of TREE's equity value. $TREE unsuccessfully fought this suit for the past 5 years while never disclosing it to investors. Image
3) We think the litigation has grown into an existential risk: in August 2024, the court certified the Plaintiff class, which LendingTree itself told the court was a "death knell" for its defense. Just 3 days ago, the judge set a November 2025 trial date. Image

1) We are short Zeta Global Holdings Corp $ZETA. Our full report is now available on our website, culperresearch.com
2) We are short $ZETA for two distinct but related reasons, each of which undermine the integrity of $ZETA's data and reported financials. First, revenue round tripping, and second, $ZETA's predatory "consent farms" that we believe generate most of Zeta's growth and Adj. EBITDA. Image
3) Just weeks ago in September 2024, the fmr CEO of Kubient pled guilty to DOJ charges of revenue round tripping fraud. We believe $ZETA was the unnamed counterparty cited in the charges. $ZETA has given only sparse disclosure of its involvement; we think its problems run deeper. Image
