On 3 May 2026, 22.7 lakh young Indians sat for NEET-UG, competing for about 1.1 lakh MBBS seats. Forty-two hours earlier, a 410-question "guess paper" was already moving on WhatsApp and Telegram. Buyers paid ₹20,000 to ₹5 lakh. About 120 of its questions matched the real exam.
On 3 May 2026, 22.7 lakh young Indians sat for NEET-UG, competing for about 1.1 lakh MBBS seats. Forty-two hours earlier, a 410-question "guess paper" was already moving on WhatsApp and Telegram. Buyers paid ₹20,000 to ₹5 lakh. About 120 of its questions matched the real exam.
Between 2012 and 2019, the catalogue records two to six major incidents per year. From 2020, the curve bends.
The 2021 cluster, the 2024 NTA crisis, and now 2026 together account for more than half of the fourteen-year total. A market that compresses willingness-to-pay also professionalises supply.
The foundational case is Vyapam, the Madhya Pradesh board, exposed in 2013 and prosecuted over a decade. Around it: UPPSC allegations in 2012, Bihar Board's "topper scam" in 2016, CBSE's WhatsApp leaks in 2018, UP TET in 2017.
What didn't yet exist was a national exam-leak market. The networks were small. The leaks were real. The two hadn't yet joined up.
Between January 2021 and June 2022, more than fifteen major recruitment exams were compromised across at least eight states: REET (16 lakh candidates), UP TET (21 lakh), Uttarakhand's UKSSSC cluster, Rajasthan's RPSC Sub-Inspector, Karnataka's PSI scam and KPSC FDA, Rajasthan's VDO and Police Constable, Maharashtra's MHADA and Health Department, Gujarat's GSSSB Head Clerk, Haryana's Gram Sachiv and Constable, the CTET, and a Western Railway recruitment exam later traced by the CBI.
This is the year when the same names start appearing on FIRs across multiple exams in multiple states. The leak ecosystem had gone professional.
In 30 days in June 2024, 4 national exams conducted by the National Testing Agency collapsed.
NEET-UG: held, then a Hazaribagh trunk breach and a Godhra solver racket. 150+ arrests across 5 states. CBI took over. The Supreme Court refused to cancel. UGC-NET: paper appeared on the darknet overnight. Cancelled the day after the exam. NEET-PG and CSIR-NET: postponed.
Four exams. ~37 lakh candidates between them. One agency. One month.
On 12 May 2026, the Centre cancelled NEET-UG and handed the case to the CBI.
It is the first full-scale cancellation of NEET-UG in NTA's seven-year history. The previous full cancellation of the predecessor exam came in 2015 — and that was a Supreme Court order, not the agency itself.
NEET 2026 isn't a one-off. It's the latest entry in this fourteen-year catalogue, and the first big test of the 2024 law passed to dismantle the market behind it.
Plot the ninety-odd incidents on a state map, and a band emerges: Bihar, Jharkhand, UP, Uttarakhand, MP, Rajasthan, Haryana, Gujarat, West Bengal — northern half, western edge, eastern recruitment-board state. Odisha and Maharashtra are not part of the classical corridor, but cluster activity there from 2023 onwards (Odisha Police SI 2025, OSSC 2023, Maharashtra's vendor-driven 2021–23 cluster) is now indistinguishable from it in scale. The South, taken as a whole, is conspicuously underrepresented.
The corridor isn't a coincidence. It traces India's largest recruitment markets and densest coaching towns. Where the demand for a government job is most intense, the market to buy a way into one is most developed.
Patna, Nalanda, Gaya, and Hazaribagh are just across the Jharkhand border. The Bihar Public Service Commission has had three exams compromised in three years. The Bihar Police Constable exam scheduled for October 2023 was cancelled after 21 lakh candidates had already sat for it. The CHO exam of December 2024 was cancelled at the testing centre.
The Hazaribagh node of NEET-UG 2024, a paper trunk recovered from a hotel room, and the Godhra node, two states away, converged, through FIRs and arrest histories, on the same Bihar-based network.
Jaipur, Ajmer, Sikar, Udaipur. The 2021 RPSC Sub-Inspector paper was leaked from inside RPSC itself. The 2022 Senior Teacher paper was intercepted on a bus from Jaipur to Udaipur. REET 2021 produced the first sacking of a state board secretary for a leak in India.
The Sikar coaching belt, India's largest NEET-prep cluster outside Kota, has appeared in arrest records for every one of these cases. In May 2026, it appears again: this time as the distribution hub for a paper printed in Nashik.
Prayagraj, Lucknow, Meerut, Varanasi. The February 2024 Police Constable exam, 48 lakh applicants, India's largest recruitment exam, was cancelled within ten days. The RO/ARO for the same month was cancelled in November following the Prayagraj protests. UP TET 2017, UP TET 2021, Lekhpal 2015: all cancelled.
Political backlash in UP is loud enough to force cancellation even when the conducting body wants to proceed. That isn't a feature elsewhere.
The same operator networks keep showing up across multiple exams in multiple states. This story names clusters by geography and exam-portfolio, not by individuals, convictions are still overwhelmingly pending.
Three clusters carry most of the case history.
The Patna–Nalanda–Hazaribagh corridor runs a recognisable handover: a printing-press insider provides an early copy, a coaching centre fronts the sale, a solver gang answers in the time window before the exam.
The same fingerprint recurs in BPSC TRE-3 (2024), 67th BPSC Prelim (2022), Bihar Constable (2023), and the Bihar node of NEET-UG 2024. The geography is logistics, not magic.
The Sikar–Jaipur–Ajmer triangle is a nexus of printing presses and coaching centres. Leaks originate at the print stage or at RPSC; coaching centres distribute them. Cross-border reach into Madhya Pradesh and Haryana.
Named in: REET 2021, RPSC SI 2021, RPSC Senior Teacher 2022, Rajasthan VDO 2021, and now the NEET-UG 2026 distribution chain that ran from Nashik to Sikar to Jhunjhunu to Dehradun. No senior operator has been convicted in the past five years.

The foundational case. Madhya Pradesh, 2013 onwards. Pre-medical, pre-PG, police constable, food inspector, contract teacher, every recruitment Vyapam touched was eventually compromised.
The two numbers: 2,000+ arrests across a decade, and at least 40+ unexplained deaths of accused and witnesses between 2013 and 2017. The Supreme Court handed the case to the CBI in July 2015, after the death count made state-level investigation untenable.
Vyapam proved two things: fraud could be industrialised, and the political protection around it was deep enough to survive a national scandal. Most of the structural failures that the 2024 reform package would later try to fix were already visible in the Vyapam files.
The most concentrated leak episode in the record. Four NTA exams. Thirty days.
NEET-UG (5 May): Hazaribagh trunk breach, Godhra solver racket, 150+ arrests. The Supreme Court declined to cancel on 23 July, calling the leak "not systemic". UGC-NET (18 Jun): paper on the darknet overnight, cancelled the day after the exam. NEET-PG and CSIR-NET: postponed.
Four months later, the Radhakrishnan Committee's verdict was that the cluster was an institutional crisis, not four bad-luck events. The NTA runs 60+ exams a year with a small staff, relying on vendor-heavy logistics and lacking in-house secure printing. The 2024 cluster was the failure mode that the design had been carrying for seven years.
The catalogue's modus operandi falls into six patterns. Printing-press breach and solver-gang impersonation lead at ~25% each. Digital circulation, Telegram, WhatsApp, the dark web — accounts for another ~20%, and it's the fastest-growing category. NEET 2026's 42-hour lead was a digital leak.
Insider compromise at the conducting body is only ~15% of cases, but does most of the causal work: leaks rarely happen without one. Cash-for-jobs with OMR substitution is just 5% by count, but in WBSS, C, it produced the largest financial scandal in the corpus.
Across the same fourteen years, none of these has produced a major confirmed paper leak: JEE Main, JEE Advanced, GATE, CAT, IBPS, SBI, NDA, CDS, CLAT, UPSC CSE. Not one.
They share a design feature: computer-based testing with randomised item delivery, or stringent in-house security. The Radhakrishnan Committee recommended migrating NEET to CBT. NEET-UG 2025 was held on paper. NEET-UG 2026 was held on paper. The format the empirical record flags as leak-prone is the format used by the most recent leak.
Every major state leak has produced a state Act. Rajasthan 2022, Gujarat 2023, Uttarakhand 2023, UP 2024, Bihar 2024. Some carry life imprisonment.
The central instrument: the Public Examinations (Prevention of Unfair Means) Act, 2024. Passed in 4 days; notified for enforcement on 21 June 2024, the same week as NEET-UG, UGC-NET, and CSIR-NET. Up to 10 years in jail and ₹1 crore in fines in the organised-crime tier. Property attachment. Cognisable, non-bailable.
Until May 2026, the central Act had not been invoked in a single major prosecution. The NEET-UG 2026 FIR, filed by the CBI on 12 May 2026, is the first invocation at national scale, alongside the Bharatiya Nyaya Sanhita and the Prevention of Corruption Act. Whether it produces a conviction is the open question.
The state Acts have produced charge sheets, but no headline conviction either. The kingpin operators named in successive FIRs across the corridor have, in most cases, been arrested before. None has yet been tried under the new law.
Two things have changed since 2024.
Posture has shifted. In July 2024, the Supreme Court refused to cancel NEET-UG. In May 202,6 the NTA itself cancelled it before anyone went to court. 22 lakh young people will sit again instead of trusting an exam they didn't. That is real progress on the procedure.
Structure has not. The Radhakrishnan recommendation, move NEET to CBT with randomised items, was not implemented in 2025 or 2026. The re-conduct will use the same paper format, vendor logistics, and printing pool. The 2024 Act will likely sit on the shelf for another year.
The fourteen-year record is consistent on one point: CBT with randomised items doesn't leak. Pen-paper recruitment exams in this market do. Until the format changes, the next leak is a date, not a hypothetical.
Compiled from CBI press releases and charge sheets, state-police statements (Rajasthan SOG, Bihar Economic Offences Unit, UP STF, Gujarat ATS, Telangana SIT, Karnataka CID), Enforcement Directorate filings, Supreme Court and High Court orders, and primary print reporting in the Indian Express, The Hindu, Hindustan Times, Scroll, The Wire, and Caravan. The May 2026 NEET facts are drawn from the CBI press release of 13 May 2026 (registering an FIR under the Bharatiya Nyaya Sanhita, the Prevention of Corruption Act, and the Public Examinations (Prevention of Unfair Means) Act, 2024), Rajasthan SOG statements of 9–12 May 2026, the NTA cancellation notification of 12 May 2026, and contemporaneous wire reporting (ANI, PTI, The Tribune, Indian Express, Deccan Herald, India TV).
Inclusion threshold: a major reported incident that produced cancellation, postponement, partial re-test, or substantial arrest activity. Single-school cheating cases and single-centre malpractice are excluded. The Northeast and Odisha are likely undercounted because investigative reporting there is thinner.
No individual accused is named in this story. The analytical claim is structural — leaks are markets and networks, not individuals, and conviction outcomes in the corpus are still overwhelmingly pending. The named-individual record is in the linked primary reporting for readers who need it.
