Météo-France has initiated an inquiry to determine whether the meteorological infrastructure managed by them was targeted by individuals seeking to influence prediction markets.

This development follows reports of highly unusual temperature spikes that triggered significant financial payouts on the blockchain-based site Polymarket, where users place wagers on real-world events.

Investigators are examining if the integrity of the national weather network was breached through physical or digital interference, as the precision of the winning bets suggests the actors involved may have had direct control over the reported data.

Online rumors, which remain unverified for the time being, claim the temperature reading was manipulated by someone using a hair dryer to generate a higher temperature.

Polymarket reportedly settles Paris temperature bets on a single Météo-France sensor sitting near the Charles de Gaulle airport perimeter.

On 6 April, the reading from the sensor abruptly rose 4°C in twelve minutes, crossing the 22°C threshold despite data from other sources showing different figures.

A user on Polymarket aggressively bet on readings above 21°C on that specific day, even though the consensus was lower at 18°C, and profited almost €30,000.

A second similar anomaly occurred on 19 April leading to suspicions that the sensor was tampered with.

Météo-France announced that it has filed a complaint with the Roissy air transport gendarmerie brigade “for [the] alteration of the operation of an automated data processing system,” after an analysis of sensor data.

Polymarket suspended its reliance on the compromised weather data source for Paris, shifting its resolution metric from the sensor in Charles de Gaulle airport to the one in Paris-Le Bourget airport.

However, it did not cancel the contracts or refund the bets, leaving the resolved contracts final, even though on previous occasions it has suspended the resolution of certain bets until further clarification on the rules and circumstances.

Decentralised ‘oracles’ and prediction markets

This incident has reignited the debate over the reliability of the “oracles” that feed data to prediction markets in order to settle bets.

In decentralised finance, an oracle is the mechanism that feeds external, real-world information into a smart contract to determine a financial outcome.

Polymarket relies on these feeds to settle its contracts, often pulling data directly from official government websites. If the primary source of that data is corrupted, the betting market lacks any internal mechanism to verify the truth.

Additionally, the decentralised nature of these platforms makes it difficult to freeze assets even if an investigation identifies the individuals behind suspicious trades.

This is the latest case that highlights a new frontier of white-collar crime, where the manipulation of the physical world is used to exploit the vulnerabilities of automated prediction markets in order to win bets on real-world events.

WASHINGTON — Amid growing national security concerns, the FBI said Tuesday that it has launched a broad investigation in the deaths or disappearances of at least 10 scientists and staff connected to highly sensitive research, including four from the Los Angeles area.

“The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and state and local law enforcement partners to find answers,” the agency said in a statement.

The FBI’s announcement comes after the House Oversight Committee announced that it would investigate reports of the disappearance and deaths of the scientists, sending letters seeking information from the agencies involved in the federal inquiry as well as NASA, which owns the Jet Propulsion Laboratory in La Cañada Flintridge, where three of the missing or dead scientists worked.

“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” Reps. James Comer (R-Ky.), chairman of the committee, and Eric Burlison (R-Mo.) wrote in the letters.

President Trump told reporters last week that he had been briefed on the missing and dead scientists, which he described as “pretty serious stuff.” He said at the time that he expected answers on whether the deaths were connected “in the next week and a half.”

Michael David Hicks, who studied comets and asteroids at JPL, was the first of the scientists who disappeared or died. He died on July 30, 2023, at the age of 59. No cause of death was disclosed.

A year later, JPL physicist Frank Maiwald died at 61, with no cause of death disclosed.

Two other Los Angeles scientists are part of the string of deaths and disappearances.

On June 22, 2025, Monica Jacinto Reza, a materials scientist at JPL, disappeared while on a hike near Mt. Waterman in the San Gabriel Mountains.

On Feb. 16, Caltech astrophysicist Carl Grillmair was fatally shot on the porch of his Llano home. The Los Angeles County Sheriff’s department arrested Freddy Snyder, 29, in connection with the shooting. Snyder had been arrested in December on suspicion of trespassing on Grillmair’s property.

Snyder has been charged with murder.

There is no evidence at this point that the deaths and disappearances, which occurred over a span of four years, are connected.

A spokesperson for NASA, which owns JPL, said in a statement on X that the agency is “coordinating and cooperating with the relevant agencies in relation to the missing scientists.

“At this time, nothing related to NASA indicates a national security threat,” agency spokesperson Bethany Stevens wrote. “The agency is committed to transparency and will provide more information as able.”

Representatives from Caltech did not immediately respond to a request for comment.

April 7 (Asia Today) — South Korea’s Labor Ministry launched a joint inspection Tuesday after a foreign worker was seriously injured at a manufacturing plant in Hwaseong, where a high-pressure air gun was allegedly used, causing internal organ damage.

The Ministry of Employment and Labor said it began a combined labor and occupational safety inspection of the facility following media reports of the incident.

Authorities plan to examine whether the worker was subjected to assault or workplace harassment, as well as possible violations of labor laws, including unpaid wages. The probe will also review compliance with safety regulations under the Industrial Safety and Health Act.

Officials said they will investigate whether the company attempted to conceal the workplace injury or failed to implement required safety measures.

If serious violations are confirmed – including abuse, harassment or major industrial safety breaches – the ministry said it will pursue strict measures such as revoking or restricting employment permits and seeking criminal prosecution.

The victim filed for workers’ compensation benefits Tuesday with the Korea Workers’ Compensation and Welfare Service, and the ministry said it will ensure the claim is processed promptly.

Separately, the ministry has been conducting broader inspections this month targeting workplaces employing large numbers of foreign workers. The inspections focus on sites suspected of labor violations, including those with frequent worker turnover, prior complaints, or records of serious accidents.

As part of the inspections, authorities are conducting surveys and interviews with foreign workers to assess workplace conditions, including potential abuse or harassment.

Labor Minister Kim Young-hoon said all workers, regardless of nationality or immigration status, are entitled to safety and dignity.

“We sincerely apologize to the injured worker and colleagues who witnessed the incident,” Kim said. “We will thoroughly investigate the case and take strict action against any violations of the law.”
