Anthropic's Claude formalizes Fermat's Last Theorem in Lean
Anthropic's Claude AI system has produced the first computer-verified formalization of Fermat's Last Theorem using the Lean proof assistant. The accomplishment represents a landmark moment: a 350-year-old mathematical conjecture now exists in a form that machines can check line by line for absolute correctness.
Fermat's Last Theorem states that no three positive integers x, y, and z can satisfy the equation x^n + y^n = z^n for any integer n greater than 2. The original proof, delivered by Andrew Wiles in 1995 after decades of effort, runs hundreds of pages and relies on advanced modern mathematics that few humans can fully verify by hand.
The Lean formalization transforms this into code. Every logical step, every definition, every inference must be explicit and valid. Claude wrote what is being called the longest proof ever produced, encoding the full chain of reasoning into machine-readable form. No mathematician needs to trust the argumen

TCS HyperVault commits $7.4 billion to Hyderabad AI data center
Tata Consultancy Services' HyperVault unit and partners are investing 700 billion rupees to build a one-gigawatt AI data center campus in Hyderabad, southern India. The facility marks TCS's acceleration into large-scale infrastructure for artificial intelligence workloads, aligning with Indian tech companies' strategic focus on domestic capacity.
The one-gigawatt campus represents significant computational power for training and running AI applications. Hyderabad's selection reflects India's broader push to develop homegrown AI infrastructure rather than relying solely on international providers. The investment signals confidence in southern India's tech ecosystem and talent pool.

Algorand crosses 1M post-quantum transactions on mainnet
Algorand has signed over 1,000,000 post-quantum transactions on its mainnet, outpacing all competing Layer 1 networks on this metric.
Post-quantum cryptography prepares blockchain infrastructure for potential threats from quantum computing. Algorand's achievement represents the highest transaction volume in this category among major Layer 1 protocols.
The milestone reflects ongoing development of quantum-resistant signing mechanisms across Algorand's network infrastructure.

Bank of Korea: stablecoins weaken local currencies via FX flows
Bank of Korea research identified a direct mechanism: dollar-backed stablecoins reduce local currency values through market maker foreign exchange activity. The study tracks how stablecoin circulation channels liquidity away from domestic currency markets, creating downward pressure on local valuations.
The mechanism works through FX intermediaries who facilitate stablecoin trades. When market makers adjust positions to manage dollar stablecoin flows, they reduce demand for local currency pairs, depressing exchange rates against the dollar.
No specific quantified impact released yet, but the finding adds central bank weight to concerns about stablecoin market structure effects on monetary stability.

Solana and Robinhood Chain dominate tokenized stock deposits
Solana hosts $79.1M in tokenized stocks within DeFi, with Robinhood Chain holding $73.1M in second place. Combined, these two chains command 79% of the category's total $192.6M in TVL.
The concentration reflects early infrastructure advantages, with Solana's speed and cost structure attracting the largest deployment, while Robinhood's native chain captures institutional interest in equity tokenization. The remaining 21% of TVL disperses across other blockchain networks.

Anthropic moves IPO target to mid-October
Anthropic is shifting its initial public offering timeline with prospectus filing now expected in late September. The AI company had previously targeted an earlier IPO window. Mid-October represents the new target date for the offering to become public.
The prospectus filing in late September will launch the formal regulatory review period ahead of the October listing. This adjustment gives Anthropic additional time for SEC review and market preparation before going public.

Institutions ditch currency hedges at 11-year low
Global investors have pulled back on currency protection across major markets. The exposure-weighted hedge ratio sits at just 41% across Japan, Canada, Taiwan and three other markets—meaning 59% of foreign currency exposure goes unprotected.
The shift is striking because hedging costs have actually fallen. Three-month Dollar hedges for Yen-based investors dropped to 2.75%, a four-year low from 6.00% in October. Euro-based investors now pay 1.32%, near two-year lows.
The 41% hedge ratio marks the lowest level since at least 2015. Investors are betting the Dollar remains resilient during market shifts rather than paying to insure against currency swings, even when protection has become more affordable. 💱
