Global X launches BDRs of rare earth and AI ETFs on B3. Global X ETFs is expanding its product offering with the launch of two new ETF BDRs. Starting July 17, Brazilian investors will be able to trade EART39, focused on companies linked to rare earths and critical materials, and CHPX39, which brings together companies from the semiconductors, artificial intelligence (AI) infrastructure, and quantum computing segments. ETF BDRs are certificates traded on B3 that represent shares of index funds listed on foreign exchanges. They allow Brazilian investors to access international strategies and markets through the Brazilian exchange, without needing to open an account with a foreign broker or operate directly on other markets. The launch comes at a time of growing demand for technologies and inputs considered essential for industrial development. The expansion of electric vehicles, energy storage systems, and data center infrastructure has driven demand for minerals such as lithium, copper, nickel, and rare earths, while the advancement of generative artificial intelligence has boosted investments in high-performance semiconductors and computational infrastructure. EART39 seeks exposure to the critical materials market. EART39 replicates the Solactive Rare Earth and Critical Materials Index, an index composed of global companies involved in the exploration, mining, production, and refining of critical materials used in various technologies. In addition to rare earths, the index includes companies linked to minerals such as lithium, copper, nickel, cobalt, manganese, graphite, graphene, palladium, platinum, and carbon-based materials. The methodology prioritizes companies classified as Pure Play, which derive at least 50% of revenue from activities related to the segment, as well as pre-revenue stage companies and diversified companies with relevant exposure to the sector. According to the manager, the goal is to offer exposure to the structural growth in demand for inputs needed for electrification, energy storage, digitalization, and industrial development. The index is rebalanced semiannually in April and October, and the management fee is 0.59% per year. CHPX39 brings together companies linked to AI infrastructure. The CHPX39 replicates the Global X AI Semiconductor & Quantum Index, formed by companies that directly participate in the global value chain of artificial intelligence, semiconductors, and quantum computing. The index includes companies involved in the development of GPUs, CPUs, ASICs, memory chips, AI-focused computing systems, data center infrastructure, and quantum computing technologies. The portfolio is organized around four main fronts: semiconductors for artificial intelligence, advanced computing systems, data center infrastructure, and quantum computing. Like EART39, the methodology favors Pure Play companies, where most of the revenue is related to these segments. Rebalancing occurs twice a year, in May and November, and the management fee is 0.50% per year. "With EART39 and CHPX39, we expand Brazilian investors' access to two structural trends directly connected to global technological transformation. On one hand, critical materials that support the energy transition and digitalization of the economy. On the other, the companies responsible for the computational infrastructure needed for the advancement of artificial intelligence and quantum computing," says Flávio Vegas, product specialist at Global X. Products are geared toward long-term strategies. According to the manager, the two BDRs were developed for investors seeking exposure to long-term structural trends through a diversified portfolio of international companies. The products will be traded daily on B3 and can be acquired through banks and brokerages. Both have a contracted market maker to provide liquidity during the trading session. As with other equity investments, ETFs are subject to market risks, currency fluctuations, and volatility in the sectors in which they invest. Because they concentrate exposure in specific segments of the economy, they may experience greater fluctuations than those observed in broad stock market indices.

The Global X Robotics & Artificial Intelligence ETF (BOTZ) offers exposure to robotics through companies already generating revenue, contrasting with Tesla's speculative Optimus bet. Tesla trades at 378 times earnings with virtually no robotics revenue, whilst BOTZ holds established players like NVIDIA, ABB and Cognex. BOTZ's top holdings include ABB (10.5%), NVIDIA (9.95%), FANUC (9.69%) and Intuitive Surgical (5.81%). NVIDIA reported 85% revenue growth in its latest quarter, whilst Cognex posted 116% gains over the past year. These companies supply compute power, machine vision and industrial robotics to the sector today. With $3.54 billion in assets and a 0.68% expense ratio, BOTZ captures robotics growth across multiple companies rather than concentrating risk in Tesla's unproven humanoid programme.

How CoinChange Financials, Inc. generate yield on BTC without selling: The covered call playbook. Every few months, a new wave of crypto holders rediscovers the same uncomfortable truth: holding Bitcoin is a conviction trade, but it pays nothing while you wait. No coupon. No dividend. No cash flow. For long-term BTC holders - institutions, family offices, corporate treasuries, and sophisticated individual investors - that is increasingly unacceptable. The conversation has shifted from "should we hold Bitcoin?" to "what should our Bitcoin be doing while we hold it?" This is exactly the question the covered call strategy was built to answer. The moment the strategy went mainstream. In 2026, covered calls on Bitcoin stopped being a niche quant approach and became Wall Street infrastructure. In April 2026, Goldman Sachs filed its first-ever Bitcoin ETF with the SEC - not a passive spot product, but a premium income fund built specifically around a covered-call overlay. The fund buys shares of existing spot Bitcoin ETFs (including BlackRock's IBIT and Fidelity's FBTC) and sells call options against that exposure to generate monthly income for shareholders. Goldman is not alone. Global X launched BCCC, a synthetic covered-call ETF on Bitcoin. Roundhill's YBTC does the same on a weekly basis. Grayscale followed with BTCC in mid-2026. And in March 2026, GameStop disclosed that it had pledged 4,709 of its 4,710 BTC to Coinbase as part of an over-the-counter covered-call program - selling short-dated calls with strikes between $105,000 and $110,000 to generate premium income from a position it had no intention of selling. The message is clear: accumulating Bitcoin is no longer enough. The institutional standard is now making Bitcoin work. The core mechanic: selling what you are not using. A covered call is one of the oldest structured income strategies in finance, adapted here for Bitcoin. OKX has a clean primer on the mechanics if you want the technical foundation - here is the practical version: Three components: * You hold spot BTC - either directly or through a custodied position. * You sell a call option against that BTC - agreeing to sell it at a set price (the strike price) on a set date. * You collect the premium - the buyer pays you upfront for the right to purchase your BTC at the strike. You keep that premium regardless of what happens next. If Bitcoin stays below the strike at expiration, the option expires worthless. You keep your BTC, keep the premium, and run the trade again. If Bitcoin rallies above the strike, your BTC gets called away at the agreed price - you miss the upside above that level, but you still pocketed the premium and sold at a profitable price. In plain terms: you are exchanging some upside potential for immediate, predictable cash flow. Where the yield actually comes from. This is the part most articles skip. Bitcoin options premiums are driven by implied volatility (IV) - the market's expectation of how much BTC will move before expiration. As The Bitcoin Layer analyzed in detail, Bitcoin's structural volatility is significantly higher than any traditional asset class, which means covered call premiums are correspondingly generous. Selling a short-dated out-of-the-money call on BTC can generate 1-4% per month in premium income depending on strike distance and expiration tenor. Annualized, that is a meaningful income stream - earned on an asset you already intended to hold. Premium is highest when: * Implied volatility is elevated - more uncertainty in the market means options cost more. * Expiration is near-term - weekly and bi-weekly options decay fastest, maximizing premium per unit of time. * Strike is closer to spot - the more "at risk" the option, the more the buyer pays for it. The art of running this strategy is calibrating the strike correctly. Most institutional programs target strikes 10-20% above spot - balancing income generation with a reasonable probability of retaining the underlying BTC. Why 2026 is the right environment. Covered call strategies perform best in range-bound or slowly appreciating markets. Sharp, violent rallies are the one scenario where you underperform a pure hold - because your upside is capped while spot runs past your strike. Bitcoin's volatility profile has changed materially. According to ARK Invest's analysis of Bitcoin risk and reward, BTC's annualized volatility has compressed from over 200% in its early years to roughly 50% today - still elevated by traditional asset standards, but measurably more predictable. This compression means: * The strategy is easier to risk-manage * Institutional counterparties are more willing to deal in size * Custody, settlement, and reporting infrastructure now supports it at scale Meanwhile, demand for Bitcoin income products is exploding. According to analysis by Amberdata, around 68% of institutional investors are currently buying or planning to allocate capital to Bitcoin ETPs. Fidelity Digital Assets' 2026 outlook documents over $564 billion in cumulative net inflows to U.S. spot Bitcoin ETFs since their launch - and a large portion of that cohort now wants yield alongside price exposure. The covered call is the cleanest structural answer. No income strategy is free. Covered calls on Bitcoin have three real costs: 1. Capped upside If BTC makes a sudden 30% move in a week, you participate only up to your strike price. The Decrypt analysis of GameStop's strategy addresses this directly: GameStop chose strike prices well above spot specifically to maximize the probability of retaining its BTC while still collecting meaningful premium. Strike selection is everything. 2. Operational complexity Running this strategy well requires systematic strike selection, expiration management, roll discipline, and continuous position monitoring. Done inconsistently, it underperforms. Done with rigor, it compounds. This is not a passive product - it rewards execution. 3. Counterparty and custody risk OTC covered calls (like the GameStop/Coinbase deal) expose you to counterparty risk - GameStop's filing noted the pledged BTC is no longer classified as directly held and instead recorded as a receivable. Exchange-traded structures eliminate this but introduce constraints on size and flexibility. How institutional programs structure it. At the professional level, covered call programs on BTC typically follow one of two architectures: Systematic weekly rolls - selling calls every 5-7 days against the full or partial BTC position, consistently harvesting short-dated volatility premium. This maximizes income frequency but requires tight execution. Roundhill's YBTCuses exactly this structure. Laddered monthly positions - staggering expirations across multiple weeks to smooth out timing risk and avoid full exposure to a single expiration event. More conservative, easier to manage, slightly lower average yield. In both cases, professional programs manage delta exposure actively - meaning the team monitors how the position's sensitivity to Bitcoin price moves changes over time, not just collecting premium and hoping for the best. A concrete example. Here is a simplified illustration of the economics: * You hold 1 BTC priced at $100,000 * You sell a 1-week call option with a strike at $110,000 * You collect a premium of $1,200 (roughly 1.2% of spot) * Bitcoin ends the week at $105,000 - below your strike * Outcome: You still hold your BTC. You pocketed $1,200. Run that consistently and the annualized income on your BTC position is in the range of 12-20% - with your underlying principal intact as long as prices stay below strike levels at expiration. The risk scenario: Bitcoin jumps to $130,000. Your BTC is called away at $110,000. You miss $20,000 of upside per BTC (but captured the premium and the $10,000 gain to the strike). In a sustained bull market, repeated occurrences of this scenario mean underperforming a pure hold. That is the honest trade-off, and anyone running this strategy professionally will tell you the same. The bottom line. The bitcoin covered call strategy is not a shortcut and it is not passive income. It is a structured trade: you exchange upside optionality for predictable cash flow, running against an asset you already believe in. The fact that Goldman Sachs, GameStop, Grayscale, and Global X all moved into this space within the same six-month window is not coincidence. The infrastructure is there, the demand is there, and the market microstructure now supports institutional scale. The question for BTC holders in 2026 is no longer whether covered calls make sense. It is whether you have the team and the process to run them well. Coinchange runs systematic options strategies on BTC and ETH for institutional clients.
