テスラとスペースXが巨大合併？その背景とは？

Tesla-SpaceX Merger Talks

On October 20, Elon Musk announced that SpaceX and Tesla are in discussions about a full business integration. If completed, the combination would bring together SpaceX — valued at approximately $2 trillion — and Tesla at roughly $1.45 trillion, creating a single company that would rank around fifth in the world by market capitalization. The procedural path would have independent directors at each company draft a merger proposal, which shareholders at both firms would then vote to approve. Because Musk is CEO and a major shareholder of each company, he will not sit on the special committees overseeing the process.

The Real Motive: Consolidating Control

Commentators acknowledge potential synergies — SpaceX using Tesla's batteries and robotics, Tesla tapping SpaceX's AI cloud — but note that such cooperation could be achieved through ordinary contracts. The deeper issue is a structural vulnerability in Musk's hold over Tesla. SpaceX operates under a dual-class share structure: Musk's Class B shares carry ten votes each, giving him roughly 80% of voting power. At Tesla, his voting stake stands at only about 20%, leaving him exposed to removal. A merger would let Musk freely pursue ambitious plans including an autonomous-driving subscription (priced in the range of tens of thousands of yen per month), a robotics business, and space-based data centers. Antitrust obstacles are expected to be modest because the two companies' business domains barely overlap, but Tesla shareholders are widely expected to raise concerns about a conglomerate discount — the tendency for diversified entities to trade at roughly 10% below the sum of their parts.

Elon Musk's Entrepreneurial History and the PayPal Mafia

In 1995, Musk co-founded ZIP2, a map and local-business information service, with his brother. He sold it in 1999 and netted ¥2–30 billion, using the proceeds to launch a financial-services company called X.com. X.com merged with rival Confinity — whose CEO was Peter Thiel (ピーター・ティール) — to become PayPal, but Musk was ousted as CEO in what amounted to a boardroom coup by Thiel while Musk was on his honeymoon. The relationship grew only more intricate when SpaceX, teetering on bankruptcy after three consecutive launch failures, was rescued by investment from that same Thiel. Thiel later became known as an early investor in Facebook and the author of *Zero to One*, in which he argues for vertical innovation — creating something entirely new — rather than competing horizontally in existing markets.

Cyberattacks by the Chinese-Language AI Agent Artex (アルテックス)

An investigation by GMO Cybersecurity by IERAE identified six overseas servers used in attacks against domestic Japanese companies between September 18 and October 18, all of which bore traces of a Chinese-language AI agent called Artex. The tool is believed to have been used in attacks on at least approximately 80 domestic companies, and its use has also been confirmed in attacks on multiple South Korean financial institutions. Artex was publicly released in July of this year for the stated purpose of helping organizations discover vulnerabilities in their own systems; its developers say malicious use was never their intent. Anthropic is developing a comparable security-diagnostic AI but has kept it private and provides it only to trusted defensive-side organizations — a sharp contrast with Artex's open release. Concrete damage continues to accumulate, including a 4.2-million-record leak from Comic Seymour (コミックシーモア) and a breach at CarSensor.net (カーセンサーネット), reinforcing a reality in which defenders have no choice but to remain perpetually vigilant.

The Rise of Covered Call Strategy ETFs

A covered call strategy involves selling call options — the right to buy a given asset — against stocks or futures one already holds, and pocketing the premium as income. The trade-off is giving up gains above a set price level in exchange for relatively stable returns in flat or gently rising markets. A representative product is QYLD, which tracks the NASDAQ 100 and has delivered roughly 9% annualized since inception. Against a backdrop of limited prospects for large equity gains, inflows have surged in South Korea and Taiwan: South Korea has seen assets grow fourfold from the end of 2025, while three ETFs launched in Taiwan since April have together attracted more than ¥490 billion. In Japan, a Nikkei-linked covered call ETF trades under securities code 2858. Using the current Nikkei level of approximately 64,000 as an illustration: a ¥70,000 call option carries zero intrinsic value yet still commands roughly 200 points — about ¥200,000 — in time value; if the index remains below ¥70,000 through the November 13 expiry, the seller keeps that full amount.
