The article profiles five quantum computing stocks that listed or expanded sharply in 2026: Quantum Computing Inc. (QUBT), Infleqtion (INFQ), Xanadu (XNDU), IQM (IQMX) and SEALSQ (LAES). QUBT held about $1.3 billion in cash and investments, and its first-quarter revenue rose from $39,000 to $3.7 million, largely due to the Luminar Semiconductor acquisition, with about $180 million spent on acquisitions this year. Infleqtion has more than $20 million in contracted NASA funding for its gravity gradiometer work, while Xanadu's plan depends on up to about $285 million from the Canadian and Ontario governments, agreements still under negotiation. IQM, which began trading on July 2 at a valuation of around $1.9 billion, faces better-funded rivals, while SEALSQ, which makes post-quantum security chips, reported $16.3 million in revenue for the first three quarters of 2026, up 65%.

- Google to Launch Crypto Custody Security System as AI & Quantum Threats Grow
Google is unveiling a crypto custody security system based on multi-party computation (MPC) to help banks and financial institutions safeguard and transfer digital assets, now in private preview with several major institutions and planned for commercial availability in early 2027. The system splits each private key into shares held in separate environments, so no single machine holds the full key, and Google says it cannot access the shares in unencrypted form. The launch comes amid concerns over private-key hacks as AI and quantum computing advance: Vitalik Buterin warned that AI-accelerated math could weaken lattice-based cryptography in 2 years, and roughly 6.9 million Bitcoin are potentially vulnerable to future quantum threats because their public keys have been exposed. Alphabet uses the system for its own assets on Ethereum and Solana.
- Quantum computing could 'brute force break' most banks' encryption
Algorand CEO William Herkelrath says quantum computing could let brute-force attacks break most banks' current encryption, so every system will need upgrading. He says the threat is on the horizon, with estimates ranging from two to three years or sooner. He notes government mandates in Europe and the United States, and that 2027 CISO budgets already include related line items. Federal agencies have until October 22 to submit upgrade plans, which cover databases, messaging systems and authenticator apps. He hopes the costs will not fall on consumers and says his company is getting more inbound interest than before.
- Crypto Firms Launch Quantum Alliance as 6 Million Bitcoin Sit Exposed
Nine blockchain organizations launched the Quantum Alliance, an open standards body that will define “quantum-ready” and set common ways to test quantum-resistance claims. The group warns that roughly 6.04 million BTC, about 30% of supply, is quantum-exposed because of elliptic-curve signatures, with forecasts pointing toward the late 2020s. A Google Quantum AI study cut the qubits needed to break Bitcoin’s cryptography to under 500,000, though no machine can do it yet. Modeled on the IETF, the Alliance will work in four groups covering migration, zero-knowledge systems, wallet security and cross-chain compatibility. Separately, a consortium backed by BlackRock, Strategy and Coinbase has committed $15 million to the problem.
- Why Hightower top investment strategist is sticking with stocks even as high treasury yields beckon
Stephanie Link, chief investment strategist at wealth manager Hightower ($350 billion in assets), is sticking with stocks even as the 10-year Treasury yield nears 6%. She argues consumer spending remains the backbone of the economy, with initial jobless claims last week at their lowest since 1969, and that growth, largely driven by AI, is pushing bond yields higher. She expects market breadth to improve after earnings as sectors like finance and industrials catch up, and sees promise in quantum computing, robotics and cybersecurity. Link sums up her approach as investing in what you know and see.
- Quantum Alliance forms amid warnings 6.4 million bitcoin face future quantum threat
Nine crypto companies have launched the Quantum Alliance to develop common security standards for bitcoin, Ethereum and other blockchains against future quantum attacks. Experts warn that a future quantum computer could derive secret keys from publicly visible keys, putting an estimated 6.4 million bitcoin at risk, including 1.1 million attributed to Satoshi Nakamoto; the Alliance says 30.2% of supply has exposed public keys, but no existing machine can exploit them yet. Researchers disagree on timing, with Richard Carback calling 2028 realistic. Proposals to freeze, move or place vulnerable bitcoin in a trust have raised concerns about property rights and neutrality, and any upgrade would require coordination across the Bitcoin ecosystem.
- Google’s Quantum Breakthrough Puts Bitcoin in Trouble? Analyst Says Not Today, but ‘Gap Is Getting Smaller’
Market research platform Bull Theory said that progress in quantum computing has narrowed Bitcoin's (BTC) long-term security gap. However, no existing machine can currently threaten the network; the comments were made in an X post reacting to news involving Alphabet.

- Earnings from Amazon, Eli Lilly, and Starbucks: What to Watch
Amazon reports third-quarter results after the bell, with Wall Street expecting revenue of just over $202 billion. Investors will focus on Amazon Web Services, whose revenue surged 37% last quarter, and on holiday shopping demand. Eli Lilly is also reporting, and analysts expect it could raise its full-year guidance again on strong demand for its weight-loss drugs, though a tougher year-over-year comparison could weigh on results. Starbucks is expected to post US same-store sales growth above 6%, helped by new drinks, food and store improvements. September's PCE index, due Thursday, is expected to tick up slightly month-over-month and could offer clues about the Fed's next rate move in December after today's FOMC hold.
- ECB President Lagarde to step down on 7 February 2027
ECB President Christine Lagarde informed the Governing Council and European Council President António Costa that she will step down on 7 February 2027. Her successor will be appointed by the European Council through the nomination process set out in Article 283 of the Treaty on the Functioning of the European Union. The Governing Council thanked her warmly and gave her a long standing ovation.
- Bank of England sets out approach to tokenised collateral in central clearing
The Bank of England has launched a consultation supporting central counterparties (CCPs) in accepting tokenised forms of eligible collateral. Tokenisation could allow faster and more efficient mobilisation and management of collateral across jurisdictions, helping firms respond to margin calls and supporting innovation in central clearing. The Bank says the existing regulatory framework is not a barrier, provided tokenised collateral can still be valued, transferred and realised when needed, including in stressed conditions. A proposed Supervisory Statement would clarify how the Bank assesses applications involving tokenised collateral, and the consultation closes on 12 February 2027.
- Alphabet and Microsoft are on both sides of the AI boom's biggest bills: Chart of the Day
Microsoft and Alphabet both rent computing power to AI labs and hold stakes in them, but this quarter Microsoft gained while Alphabet lost: Microsoft shares rose about 2% after hours, while Alphabet fell nearly 10%. OpenAI paid Microsoft $10 billion in the quarter ended September, about 11% of its $92 billion revenue, but unpaid OpenAI bills rose to about $7 billion and Microsoft's backlog slipped to about $677 billion. Alphabet's holdings, including about 14% of Anthropic and a stake in SpaceX, produced a nearly $9 billion loss that cut earnings by $0.55 a share to $2.12. Alphabet spent $51 billion on data centers and equipment and burned about $9 billion in free cash flow for a second straight quarter, funding the gap with $29 billion of bonds and $12 billion of new shares. Google Cloud revenue doubled to about $31 billion, and its backlog rose to $561 billion from $514 billion.
- Is Plug Power Under $1.50 a Bargain or a Trap? Here's the Honest Answer.
Plug Power (PLUG) shares are down roughly 52% over the past year, trade near their 52-week low, and sit below $1.50 per share. In Q2, revenue rose roughly 9% year over year to about $178 million and gross margin reached breakeven, up from -31% a year earlier, though the company still posted a net loss of roughly $190 million. Plug Power reported about $134 million in cash and equivalents and said Q3 net cash usage was just $28 million. However, the article suggests another large loss is likely and that continued stock dilution is a very likely outcome, as the share count has risen more than 140% over the past five years.
- PJX Resources Commences First-Ever Drilling at High-Priority Gar Gold Target on Zinger Property
PJX Resources has started its first-ever drilling at the high-priority Gar gold target on its Zinger Property in southeastern British Columbia, following renewal of the property's five-year drilling permit. The program will test a 1,600-metre-long gold-in-soil anomaly, with geological traits similar to Snowline Gold's Valley discovery and Kinross Gold's Fort Knox deposit. Grab samples from surface quartz veins returned gold values of up to 28.84 g/t, and visible gold has been seen in the veins. At the Dewdney Trail Property, about 2,700 metres of a planned 4,000-metre program is complete at Estella Basin; due to deteriorating weather, drilling there was postponed until next year and the drill was moved to Gar. Given the target's size and the approaching winter, the initial Gar program will test only part of its potential.
