On 26 March 1997, 39 members of the Heaven's Gate religious movement were found dead at a rented mansion in Rancho Santa Fe, California. They had ingested phenobarbital mixed with vodka and applied plastic bags to their heads. Leader Marshall Applewhite had taught that a spacecraft trailing comet Hale-Bopp would transport their souls to a higher realm. Claims of government cover-up or institutional concealment are unsupported: the investigation was transparent, Applewhite's videotaped teachings are publicly available, and the deaths were thoroughly documented.

On 9–10 August 1969, Manson Family members murdered seven people including actress Sharon Tate in the Tate/LaBianca killings in Los Angeles. Prosecutor Vincent Bugliosi's "Helter Skelter" theory — that Manson directed the murders to trigger a race war he believed the Beatles' White Album prophesied — was established at trial, resulted in convictions, and is well-evidenced by testimony and Manson's own statements. The "Helter Skelter" doctrine was itself the conspiracy: a plan Manson designed and directed.

The MUSCULAR programme, revealed by the Washington Post in October 2013 based on Snowden documents, showed that the NSA and GCHQ had secretly tapped the unencrypted fibre-optic links connecting Google's and Yahoo's data centres to one another. Unlike PRISM, which used legal orders to compel disclosure, MUSCULAR accessed data in transit on private backbone infrastructure without the companies' knowledge. The disclosure prompted both companies to encrypt their internal links. MUSCULAR is confirmed by NSA slides published by the Washington Post.

In June 1998, CNN's NewsStand programme broadcast a report claiming that US Special Forces used sarin nerve agent during Operation Tailwind in Laos in September 1970, specifically to kill American defectors. CNN retracted the report in July 1998 after an independent review by First Amendment attorney Floyd Abrams found the claim was not supported by the evidence gathered. The two producers responsible were dismissed. Operation Tailwind itself was a real classified SOG mission; the sarin-on-defectors claim is the fabricated element, retracted by the news organisation that aired it.

The Lavon Affair (also called Operation Susannah) was a failed Israeli covert operation in 1954 in which Egyptian-Jewish agents recruited by Israeli military intelligence carried out a series of bombings against British and American targets in Cairo and Alexandria. The operation was designed to be attributed to the Muslim Brotherhood or Egyptian communists, with the aim of destabilising the relationship between Egypt and the Western powers and discrediting the Nasser government. The network was exposed by Egyptian security services; Israeli defence minister Pinhas Lavon resigned over the affair in 1955. Israel officially acknowledged the operation in 2005.

Project Azorian was a classified CIA operation in which the purpose-built ship Hughes Glomar Explorer raised portions of the sunken Soviet ballistic-missile submarine K-129 from a depth of approximately 16,500 feet in the Pacific Ocean in 1974. The project used a Howard Hughes cover story — ostensibly a deep-sea mining vessel — to conceal the operation. It was partially declassified in 2010. The operation is fully confirmed and represents one of the most technically ambitious covert operations in history.

Operation Gladio was a NATO-coordinated programme of clandestine "stay-behind" networks established across Western Europe from the late 1940s, designed to conduct sabotage and resistance operations in the event of a Soviet invasion. The networks were armed, trained, and funded by CIA and MI6 and operated in coordination with national intelligence services. Italian Prime Minister Giulio Andreotti disclosed the Italian network to parliament in August 1990. The Italian parliamentary commission and subsequent national investigations in Belgium, France, Germany, and Switzerland confirmed the programme's existence across the continent.

GlaxoSmithKline's diabetes drug Avandia (rosiglitazone) was approved by the FDA in 1999. A 2007 meta-analysis by cardiologist Steven Nissen, published in the New England Journal of Medicine, found that Avandia was associated with a 43% increased risk of myocardial infarction. Senate Finance Committee investigations in 2010 found that GSK had internal evidence of cardiovascular risk years before the Nissen publication and had not disclosed it to regulators. GSK settled with the US Department of Justice for $3 billion in 2012 — at the time the largest healthcare fraud settlement in US history — covering Avandia and other products. The FDA restricted Avandia to patients with no other options in 2010 and lifted the restrictions only in 2013 after further review.

JUUL Labs launched its e-cigarette in 2015 with marketing that regulators and litigants found deliberately targeted underage users: bright colours, social media influencers, flavoured pods, and campaigns that mirrored cigarette advertising strategies proven to recruit teen smokers. Between 2017 and 2019, teen e-cigarette use surged to epidemic levels — the FDA called it a "youth vaping epidemic." In June 2022, the FDA denied JUUL's marketing authorisation, citing inadequate safety data. In December 2022, JUUL settled a 33-state attorney general investigation for $462 million. Separate settlements with school districts and individual states totalled additional hundreds of millions. The targeting of minors is confirmed by internal documents, regulatory findings, and legal settlements.

Merck launched the painkiller Vioxx (rofecoxib) in 1999 despite internal data suggesting elevated cardiovascular risk. The VIGOR trial (2000) showed a five-fold increase in heart attacks versus naproxen; Merck downplayed the finding for four years. APPROVe (2004) confirmed the risk and Merck withdrew Vioxx globally. The FDA estimated 27,000 to 55,000 excess cardiovascular deaths during the drug's five years on the market. Merck settled MDL 1657 for $4.85 billion in 2007. Internal emails show executives debating how to "handle" the cardiovascular signal. This is a confirmed corporate concealment, not a disputed claim.

A Reuters investigation published in December 2018 found that Johnson & Johnson knew for decades that its baby powder talc sometimes tested positive for asbestos, a known carcinogen, and did not disclose this to regulators or the public. Internal J&J documents dated from the 1970s through the early 2000s showed awareness of asbestos contamination in talc sourced from mines in Vermont and elsewhere. In 2018, a Missouri jury awarded $4.69 billion to 22 women who alleged asbestos-contaminated talc caused their ovarian cancer (Ingham v. Johnson & Johnson). J&J discontinued US and Canadian baby powder sales in 2020 and global sales in 2023. Two attempts to resolve talc liability through bankruptcy of a subsidiary (LTL Management) were rejected by federal courts in 2023.

Theranos, founded by Elizabeth Holmes in 2003, claimed its proprietary Edison device could run hundreds of diagnostic tests from a single finger-prick of blood. The technology never worked as claimed. A 2015 Wall Street Journal investigation by John Carreyrou exposed the fraud. The company voided two years of Edison-based test results, affecting approximately 176,000 patients. Holmes was convicted of four counts of wire fraud (January 2022, sentenced to 11 years). President Balwani was convicted of 12 counts (July 2022, sentenced to nearly 13 years). Patients received false medical results; some made clinical decisions based on inaccurate data.

FTX, the cryptocurrency exchange founded by Sam Bankman-Fried (SBF), secretly transferred billions in customer deposits to its affiliated trading firm Alameda Research, which used the funds for investments, loans to executives, and political donations. When Alameda's balance sheet leaked in November 2022, a bank run ensued and FTX collapsed. SBF was convicted on seven counts of fraud and conspiracy in November 2023 and sentenced to 25 years. Testimony from co-conspirators Caroline Ellison and Gary Wang confirmed the Alameda auto-liquidation exemption and the deliberate nature of the commingling.

Tether Limited, issuer of the USDT stablecoin, claimed for years that each USDT was backed 1:1 by US dollars held in reserve. Investigations by the New York Attorney General (settled February 2021, $18.5M) and the CFTC (settled October 2021, $41M) confirmed that Tether had misrepresented its reserves — backing was at times composed of commercial paper, loans to Bitfinex, and other non-cash assets rather than pure dollar reserves. Tether produces periodic attestations but has never undergone a full independent audit. The stablecoin continues to operate and is the largest by market cap.

Mt. Gox, once the world's largest Bitcoin exchange, collapsed in February 2014 after announcing the loss of approximately 850,000 BTC (then ~$450M; worth billions at later prices). CEO Mark Karpelès initially claimed transaction malleability attacks were responsible. Independent blockchain forensics firm WizSec attributed the losses to systematic key theft beginning in 2011. Karpelès was convicted in March 2019 for data falsification — not theft. Alexander Vinnik, operator of BTC-e (a money laundering exchange), was indicted in 2017 for receiving proceeds of the Mt. Gox theft. The true mechanism remains partially contested.

TerraUSD (UST) was an algorithmic stablecoin designed by Terraform Labs and its CEO Do Kwon. In May 2022, the UST peg collapsed, triggering a "death spiral" that wiped approximately $40 billion in market value within days. The SEC filed fraud charges in February 2023. Do Kwon was arrested in Montenegro in March 2023 and extradited to the United States in 2025. Evidence at trial showed Kwon and colleagues had privately known the stablecoin mechanism was fragile and had concealed its prior near-collapse in May 2021.

Silicon Valley Bank (SVB) collapsed on 10 March 2023 in the second-largest US bank failure in history. Conspiracy claims attributed the failure to coordinated short-selling campaigns or deliberate destabilisation by financial actors. Federal Reserve, FDIC, and congressional investigations attributed the collapse to SVB's concentration of approximately $91 billion in long-duration mortgage-backed securities purchased at near-zero interest rates, which lost market value as rates rose. When SVB announced a $1.8 billion realised loss from selling securities on 9 March, a Twitter-accelerated bank run ensued. Short-seller conspiracy claims are unsupported.

Whitney Houston was found unresponsive in a bathtub at the Beverly Hilton Hotel on 11 February 2012 and pronounced dead at age 48. The Los Angeles County coroner ruled the cause of death accidental drowning with cocaine use and atherosclerotic heart disease as significant contributing conditions. Within hours of the announcement, online conspiracy communities advanced the claim that Houston had been an Illuminati 'sacrifice' — killed by the music industry or a shadowy elite cabal. The claim has no forensic, documentary, or testimonial basis.

Prince Rogers Nelson was found unresponsive in an elevator at Paisley Park on 21 April 2016. The Midwest Medical Examiner ruled the cause of death accidental fentanyl toxicity. The fentanyl was in counterfeit Vicodin pills. The FBI investigated whether any party could be held criminally responsible for supplying the pills; the investigation closed in 2018 without charges. The counterfeit-fentanyl supply chain was real and responsible for many deaths in 2016. The claim that Prince was specifically, deliberately targeted for murder via poisoned pills has no evidentiary support.

R&B singer Aaliyah Dana Haughton and eight others died when a Cessna 402B crashed shortly after takeoff from Marsh Harbour Airport in the Bahamas on 25 August 2001. The National Transportation Safety Board investigation determined the probable cause was weight overload and the aircraft being piloted by Luis Morales III, who was not rated for the aircraft type and whose toxicology showed cocaine and alcohol. The claim that the crash was a cover-up or an orchestrated killing has no evidentiary basis and directly contradicts the NTSB findings.

Malcolm McCormick (Mac Miller) died on 7 September 2018 at his Studio City, California home from acute mixed drug toxicity — fentanyl, cocaine, and alcohol. The Los Angeles County coroner ruled the manner of death accidental. Three individuals were subsequently prosecuted for their roles in the fentanyl supply chain: Cameron Pettit (pleaded guilty 2021), Ryan Reavis (pleaded guilty 2022), and Stephen Walter (convicted 2023). The 'industry sacrifice' claim has no basis; the counterfeit-pill-supply-chain prosecution is real.

Jahseh Dwayne Ricardo Onfroy (XXXTentacion) was shot and killed during a robbery outside a motorsports dealership in Deerfield Beach, Florida, on 18 June 2018. Four men were convicted of first-degree murder and armed robbery in October 2023: Dedrick Williams, Michael Boatwright, Trayvon Newsome, and Robert Allen. The prosecution established a robbery motive — the perpetrators targeted XXXTentacion for cash he was known to be carrying. The claim that a rival record label orchestrated the killing has no evidentiary basis and contradicts the conviction record.

Rapper Jarad Higgins (Juice WRLD) died at Chicago's Midway Airport on 8 December 2019 after swallowing multiple Percocet pills. The Cook County Medical Examiner ruled the cause of death oxycodone and codeine toxicity. Federal agents were present, boarding his private jet as part of a firearms and drug search. Conspiracy framings range from "the encounter caused panic that led to the fatal swallow" (partially supported by witness accounts) to "agents deliberately murdered him" (no evidentiary basis). The intermediate claim — that the enforcement encounter was a proximate contributor — is partially coherent; the murder claim is not.
