Solana’s first major consensus upgrade, Alpenglow, went live on mainnet around 1:54 pm UTC on Wednesday, according to the Solana Foundation’s dashboard. The upgrade aims to cut transaction finality by 99%, from about 12.8 seconds to roughly 150 milliseconds, by replacing the current voting and finalization mechanism with direct validator voting. At press time, mainnet showed 6.6-second finality and 4,721 transactions per second. A later phase, Rotor, is meant to replace Turbine for block data distribution, and Anza called Alpenglow the biggest change to Solana’s core protocol since genesis. SOL rose nearly 3% in the 24 hours before the upgrade, reversing part of a 42% decline over the past year.

- Solana Governance Vote Backs Faster Disinflation After Bug Fix
Solana voters approved SGP-0002 with 67.00% support, above the 66.67% threshold, a proposal to double the annual disinflation rate from 15% to 30% while keeping the long-term inflation target at 1.5%. The vote followed a fix to a governance flaw that could have left independent staker ballots out of the count if their validator never voted. Asymmetric Research estimated that support would have been 66.65% under the earlier software, 0.02 percentage point below the threshold, based on 212 independent ballots representing 2.81 million SOL. The vote approved the direction of the change but not a new schedule, which still requires acceptance and activation of SIMD-0550.
- Solana treasury firm SkyAI sells all SOL holdings, launches $201M buyback
SkyAI, formerly Sharps Technology, has sold its entire Solana (SOL) treasury and launched a tender offer to buy back up to $201.3 million of shares and warrants, reversing its crypto accumulation strategy. As of Oct. 16 the company held about $223.8 million in cash, and the offer covers up to 95% of each class of shares and warrants at a fixed price, no longer tied to SOL's price as originally planned. The company says it will keep building a financial platform that combines stablecoin infrastructure on Solana with artificial intelligence. The strategy began in August 2025 after a private placement of more than $400 million, and by the end of 2025 it had produced about $153 million in unrealized losses. SkyAI shares closed Monday at $2.79, up 5.3% on the day.

- Solana Alpenglow Goes Live in 'Most Ambitious' Upgrade Since Ethereum's Merge
Solana's new Alpenglow consensus protocol has gone live on mainnet-beta, replacing TowerBFT, which the network had used since March 2020, according to developer Anza. Transaction finality drops from about 12.8 seconds to roughly 150 milliseconds, a change Anza says matters for exchanges, banks and merchants. The upgrade passed public testing and was approved by validators with 98% of votes in September 2025, while future upgrades such as Rotor and Quantumglow, a post-quantum version, have no committed dates.
- Qubic restarts blockchain, opens recovery claims after $1.4M hack
Layer-1 blockchain Qubic restarted its network and opened a recovery process after an attacker drained roughly $1.4 million in QU tokens from 1,404 accounts by exploiting predictable wallet seeds. The network was halted on Sunday to stop stolen funds from moving and resumed processing on the evening of Oct. 19. Its validators, known as Computors, approved the recovery plan, and affected users can check their address and file claims until May 1, 2027. The flaw came from an insecure random-number generator in Qubic's web wallet on certain Apple devices and browsers, and the project says wallets created before version 4.26.4 should be treated as insecure, with users advised to update, create a new wallet and move their funds.
- Sophon sets Nov. 25 withdrawal deadline ahead of mainnet shutdown
Sophon has set a November 25 deadline for users to withdraw their assets before it shuts down its mainnet, with key infrastructure and related websites going offline that day. Assets left on the Sophon Chain could become permanently inaccessible, so users are asked to withdraw SOPH, ETH, USDC and other assets and claim any outstanding staking or Guardian rewards. In June, developers said maintaining a standalone blockchain no longer justified its benefits and shifted focus to consumer finance and AI applications on Base. The shutdown follows Abstract’s announcement that it will close on December 15 after Igloo lost tens of millions of dollars supporting the network.

- SpaceX Just Reported a 161% Jump in Quarterly Revenue. Wall Street Analysts Were Off by $1.6 Billion as Stock Soars 9%
SpaceX reported third-quarter revenue of $14.6 billion, up 161% year-over-year and above the $13.02 billion consensus. Its Super Intelligence business, which leases AI computing power and sells Grok products and Cursor, generated $7.6 billion, up 830%, while Connectivity revenue rose 69% to $5.2 billion with 13.6 million consumer subscribers. The company posted $2.8 billion in operating income and $4.4 billion in net income versus a $1.1 billion net loss a year earlier, though capital spending reached $19.6 billion and is expected to be $35 billion to $40 billion in the fourth quarter, and some margin benefit came from one-time tariff refunds. Elon Musk said a combination with Tesla 'would be a good idea', but the special committees have not agreed on any terms, and SpaceX guided first-quarter 2027 revenue to $33 billion to $37 billion. Shares rose 9.4% to $161.64 in early trading.
- New energy shock hits Germany
Producer prices for refined petroleum products in Germany rose 51.3% year on year in September, according to Destatis, with heating oil up 91.8% and motor fuel up 48.6%. Overall producer prices climbed 6.7%, the steepest rise since March 2023, while Germany's crude oil import costs rose 21.7% to €30 billion in the first eight months of 2026. Destatis attributed the increase to higher crude prices amid the Middle East conflict; the report also cites disruption in the Strait of Hormuz and Brent topping $111 a barrel on October 20. Germany has faced higher costs since halting Russian gas imports, and Berlin reportedly spent about €50 billion to cushion the impact. Meanwhile, corporate insolvencies in the first half of 2026 reached their highest level in 13 years.
- AI's billion-dollar question: When will the spending pay off?
Speakers in this discussion argue AI infrastructure spending faces a timing gap, since months can pass between when computing hardware ships and when it starts earning revenue, leaving a large amount of capital tied up. As an example, a buyer of $10 million in Nvidia chips may need six months to get them running while that money sits on its balance sheet. They also point to a wider gap between total AI spending and the revenue it generates, and note that some reports suggest the size of returns may depend on technological innovation. Easing supply chain bottlenecks, they say, would help companies bring computing capacity online faster.
- Here's how Meta's earnings could end up being a recipe for disaster
Meta's earnings report tonight is closely watched because it sits at the intersection of the AI spending story and the advertising business that funds it. Investors want to know whether AI is helping advertisers reach customers and generate enough extra revenue to justify the infrastructure investment, and how much more Zuckerberg plans to spend. Meta shares lost $12 yesterday and were rising back to around 490 this morning. The speaker argues that if Zuckerberg shows profits can grow alongside spending, confidence in the AI trade will be restored, but a bigger spending plan without convincing earnings growth would be a recipe for disaster.
- Prediction: Nvidia’s Road to $1 Trillion in Annual Revenue Could Transform Its Stock
Nvidia reported $96.22B in quarterly revenue, up 105.8% year over year, and guided to $108B for the current quarter, yet the stock is up only 15.08% year to date. The article says reaching $350 in 2027 would require a 63.5% gain from the $214.13 price, and its model's central estimate is $258.42. Key risks include investor worries about AI funding, $279B in supply commitments, and guidance that excludes China data center compute revenue. The author says this scenario depends on Vera Rubin ramping as the fastest launch in Nvidia's history, supply easing and markets not pricing in a funding scare, calling $350 'a stretch, but a credible one.'
- Ex-Google CEO got the job after a Burning Man trip with Larry Page. Now an ex’s intro could make him $20B on Anthropic
Eric Schmidt was vetted by Sergey Brin and Larry Page and hired as Google's CEO after an unconventional interview process, with Brin citing Schmidt as the only CEO finalist who had gone to Burning Man. In 2011, Schmidt began dating Camilla Clark for three years; she later married Anthropic CEO Dario Amodei. In 2018, that connection led Schmidt to meet with her and her then-partner to discuss Anthropic, and he invested early and now owns about 1% of the company. According to the Financial Times, Anthropic could be valued at as much as $2 trillion in an IPO, which could make Schmidt's stake worth $20 billion, more than half his current net worth per Forbes, compared with the roughly $461 million valuation when he invested.
