Justice Department Sues Visa Over Debit Network Monopoly

The U.S. Justice Department has sued Visa, accusing it of maintaining an illegal monopoly over debit payments. The suit claims Visa used "exclusionary" agreements to stifle competition and inflate fees, costing consumers and merchants billions. Attorney General Merrick Garland stated that Visa's monopoly affects the price of "nearly everything."

Visa, with over 60% of U.S. debit transactions, charges over $7 billion annually in processing fees. The DOJ alleges Visa threatened merchants and banks with higher rates if they used competitors, maintaining a dominant position. Visa's agreements with tech giants like Apple and PayPal, designed to neutralize potential threats, also stifled innovation.

Visa called the suit "meritless," arguing it operates in a competitive market with thriving new entrants. However, the DOJ seeks court intervention to prevent Visa's anticompetitive practices.

This lawsuit comes amid heightened regulatory scrutiny of payment networks. Recent deals, like Capital One's acquisition of Discover, aim to challenge Visa and Mastercard's dominance. The outcome could reshape the payment landscape, impacting fees and innovation.

Mapping the Fruit Fly Brain: A Breakthrough in Neuroscience

Researchers have mapped the entire brain of a fruit fly, detailing 139,255 neurons and 50 million connections. This wiring diagram, or connectome, took years to complete. It involved slicing the fly’s brain into 7,000 sections, imaging each with an electron microscope, and using AI to trace neuron paths. Human volunteers corrected AI errors.

The project classified over 8,400 cell types, providing a blueprint for a fly brain. Researchers found neurons that process diverse information and coordinate neural activity. They also identified circuits that halt fly movement.

A computer simulation of part of the fly brain revealed taste processing circuits. This suggests future simulations could explain brain wiring’s role in behavior.

The effort involved researchers from Canada, Germany, and the UK. They published their findings in nine Nature papers. Dr. Anita Devineni called the wiring diagram a “landmark achievement.”

Next, researchers aim to map the mouse brain within five to ten years. Mapping the human brain, with its 86 billion neurons, is far more complex. It would require a zettabyte of data—equivalent to a year’s internet traffic.

Instead, researchers may map parts of the human brain. This could help understand neuropsychiatric disorders. Dr. John Ngai of the US National Institutes of Health emphasized the importance of understanding brain wiring to address brain disorders.

OpenAI Secures $66 Billion Investment, Valuation Surges to $1570 Billion

OpenAI has secured a $66 billion (approximately ¥463 billion) investment, boosting its valuation to $1570 billion (approximately ¥11 trillion). This marks the company's largest venture capital deal to date. The funding round was led by Thrive Capital, with Microsoft, NVIDIA, and SoftBank also participating. Notably, Apple did not join this round.

The investment is structured as convertible debt, meaning it will convert to equity if OpenAI transitions to a for-profit entity within two years. If not, OpenAI must repay the debt. This move aims to enhance OpenAI's leadership in AI research, boost computational power, and develop AI tools to solve complex problems.

OpenAI predicts its revenue will surge from $37 billion this year to $116 billion next year, then double again to $256 billion by 2025, and reach $1000 billion by 2029.

The deal also includes a unique clause for Thrive Capital: if OpenAI meets revenue targets, Thrive can invest an additional $10 billion at a $1500 billion valuation next year. This could yield significant returns for Thrive.

OpenAI's transition to a for-profit entity faces substantial legal hurdles, requiring complex asset redistribution. The company must compensate its original non-profit structure, which could be challenging given the rapid growth since ChatGPT's launch.

This funding propels OpenAI into a new era, attracting more investors. However, the company must address core issues like leadership changes, safety concerns, and revenue generation to satisfy its new stakeholders.
