Crypto's biggest moves came from the edges this week, AI, TradFi and consumer apps all pushing deeper onchain, while capital chased the leaders.

Five moves that actually mattered:

— Nvidia agrees to buy Hugging Face for $12.9B

— Polymarket is raising $1B at a $21B valuation, up from $15B

— Durov ships Gram Wallet, a non-custodial wallet built into app

— Solana passes SIMD-0550, doubling SOL disinflation to 30%

— Bybit turns on 24/7 options on stock perpetuals

Anthropic released Claude Fable 5.1 and Mythos 5.1, calling them the world's most advanced models for coding and knowledge work. Fable 5.1 is generally available, while Mythos 5.1 ships through trusted-access programs with safeguards built for cybersecurity and the life sciences.

Fable 5.1 costs about 25% less than Fable 5 for typical token-billed workloads, with heavily agentic tasks saving up to roughly 45%, driven by cheaper cache reads. It also debuts Enterprise Frontier Safeguards, giving enterprises zero-data-retention privacy by keeping data on customer-controlled cloud infrastructure rather than Anthropic's.

On benchmarks it sets a new frontier, scoring 52.6% on Terminal-Bench-Science against Fable 5's 24.7%, and topping Opus 5 and GPT-5.6 on agentic coding and reasoning. In testing at hedge fund Millennium, it traced the root cause of a years-old crash that no engineer or rival model had cracked.

Anthropic also framed the launch as an early glimpse of AI-driven science: Mythos 5.1 designed protein binders with roughly 10 times higher affinity than the best prior competition entries, while Fable 5.1 built a sharper elevation map covering a third of Venus from decades-old NASA radar data.

Twenty-one major financial institutions including Bank of America, Citi, Goldman Sachs, Deutsche Bank, UBS, Fidelity Investments, Wells Fargo and MUFG have committed to establish a new company in H2 2026 to support stablecoin issuance.

The group plans to launch a USD-denominated stablecoin in H1 2027, with additional G7 currencies to follow and the euro as a priority. The stablecoin will target wholesale, institutional and retail use cases, including cross-border payments and digital asset settlement.

The initiative is expected to comply with the U.S. GENIUS Act and EU MiCA where applicable, bringing some of the world's largest financial institutions together to build regulated stablecoin infrastructure.

The move highlights growing institutional adoption of stablecoins, as major banks and financial firms increasingly position dollar-based digital assets as infrastructure for payments, settlement and the broader onchain financial system.

Stablecoin remittance startup Felix Pago raised a $200 million Series B led by a16z, splitting the round into $87 million of equity and a $113 million credit facility from General Catalyst's Customer Value Fund.

Miami-based Felix Pago lets users in the US send money to Latin America through WhatsApp, settling on the backend with Circle's USDC and blockchain rails. It has processed more than $8 billion in remittances to date, a sharp step up from its $75 million raise in April 2025 and a $15.5 million Series A the year before.

With the fresh capital, the company plans to expand beyond transfers into lending and savings products for Latin American immigrants, and to build an AI-powered financial assistant.

The round is another sign of investors piling into stablecoin payments, betting that dollar-pegged rails can undercut legacy remittance costs and pull everyday cross-border finance onchain.

Parlay stacks predictions into one high-multiplier bet. Pascal trades events like perps. SnapMarkets resolves in 30 seconds. Kash lives inside your X feed.

The space is specializing fast. Check the full breakdown.

August 2026 had 31 calendar days. Crypto got hacked on 16 of them, totaling $147.3M lost across 20 incidents (>$500K). One breach dwarfed the whole month: Tectonic's $75M on the 30th alone was over half the total damage.

Kraken parent Payward and the London Stock Exchange are partnering to bring UK stocks onchain, tokenizing the 100 largest London-listed companies as xStocks for 24/7 trading.

Subject to regulatory approval, the LSE will begin listing xStocks and supporting their trading on LSE 24, its newly announced 24-hour venue that is set to eventually span tokenized US, EU and UK equities. The two firms will also explore native, LSE-issued equity tokens that let exchange members issue and serve shares directly onchain.

The partnership could open UK-listed shares to investors in more than 110 countries, though xStocks remain unavailable to UK and US residents for now.

In just over a year, xStocks have generated more than $40 billion in total trading volume, nearly $20 billion of it settled onchain, and now count more than 200,000 holders, according to Payward.

Ethena launched Ethena Pay, its stablecoin neobank, on Avalanche, letting users hold a synthetic dollar and earn a 6% savings rate straight from the app.

The 6% is generated by sUSDe, Ethena's staked synthetic dollar, which pays a yield sourced from funding rates and reserve income. It now settles natively on Avalanche after USDe and sUSDe went live across the chain, with liquidity and lending support from venues like Uniswap, LFJ and Euler.

The move is Ethena's clearest step yet toward becoming a consumer neobank, bundling dollar savings, payments and yield into one app rather than a pure DeFi protocol.

Yield-bearing stablecoins are fast becoming the headline feature for onchain neobanks, with a wave of apps racing to pair everyday spending and savings against tokenized dollars.

Fomo acquired the technology, IP, and team of Mobula, an onchain data and trading-infrastructure platform, for $17M. The move brings a data stack Fomo already relied on fully in-house as the app scales.

Mobula's real-time APIs and security-enriched endpoints had been quietly powering core parts of Fomo, from its scam-detection to its social discovery features. With the deal, Mobula's engineering leadership joins Fomo, while Mobula itself continues to operate as an independent entity.

The acquisition lands during a sharp growth run: Fomo says its user base has more than doubled to over 1.9 million since early July, adding upward of 30,000 users a day, with monthly volume projected to climb from $500 million in June to roughly $2.8 billion in August.

Owning the data layer, rather than renting it, gives Fomo tighter control over the infrastructure behind its fastest-growing features.

Andreessen Horowitz topped up its fifth growth fund to $8.5 billion, adding about $1.75 billion since the vehicle launched in January at $6.75 billion.

The expansion came just days after a16z closed a separate $1.1 billion Machine Age fund dedicated to AI hardware, covering semiconductors, networking, storage, data-center infrastructure and robotics.

The growth fund is a general late-stage vehicle rather than a crypto-specific one. Across its five vintages, a16z's growth strategy now exceeds $24 billion and backs more than 100 companies through their scaling phase.

The back-to-back raises underline how aggressively a16z keeps building dry powder even as parts of the venture market cool, cementing its place among the largest and most active investors across tech and crypto.
