Walter Isaacson, the biographer of Elon Musk, predicts that Tesla Inc. and Space Exploration Technologies Corp. are headed toward a merger, a scenario that could significantly benefit Exchange Traded Funds (ETFs) holding Tesla. Isaacson stated that a combination makes sense given both companies build physical products driven by artificial intelligence, and tracking engineers across separate entities is inefficient. The prediction follows SpaceX's record public debut, which has settled into public trading while Tesla shares have faced a 15% year-to-date erosion.

Isaacson told CNBC that a Tesla-SpaceX merger buyout is logical. He noted that the movement of talent between Musk's companies carries legal implications, referencing a Delaware shareholder suit alleging Musk siphoned AI talent and Nvidia chips from Tesla to xAI, a startup now folded into SpaceX. A merger could resolve these governance gray areas. Isaacson also remarked that Musk treats his net worth as capital to be redeployed within his companies rather than personal wealth.

Prediction market traders on Kalshi have increased the odds of a Tesla and SpaceX combination by May 2027 to roughly 57%, up from 52% earlier in the month. The contract stipulates that a "yes" resolution occurs if Tesla buys SpaceX, SpaceX buys Tesla, or the two combine under common ownership. Wedbush analyst Dan Ives has assigned a greater than 80% probability to a future combination.

Valuation dynamics present a complex picture for any potential deal. SpaceX is currently worth about $2.182 trillion compared to Tesla's $1.5 trillion, suggesting SpaceX could be the acquirer based on size alone. However, SpaceX posts losses while Tesla generates a profit, which may complicate share valuation in a swap ratio. Morningstar analyst Seth Goldstein has argued that SpaceX's lofty valuation could complicate negotiations.

The merger thesis is largely centered on artificial intelligence rather than electric vehicles or rockets. SpaceX absorbed xAI earlier this year, bringing Grok and other AI assets into its orbit. Tesla, meanwhile, continues to invest heavily in autonomous driving, humanoid robots, AI infrastructure, and semiconductor initiatives. The companies are also reportedly collaborating through a semiconductor manufacturing venture known as Terafab. A combined company would create one of the market's most expansive AI ecosystems.

Tesla remains a major holding across many popular growth and technology ETFs, including the Roundhill Magnificent Seven ETF, ARK Innovation ETF, Invesco QQQ Trust, and ARK Autonomous Technology & Robotics ETF. Roundhill Investments CEO David Mazza suggested that Tesla may already be trading at an acquisition premium, stating, "What is holding Tesla above $400 is an acquisition premium building in." If investors continue assigning a merger premium to Tesla shares, these funds could indirectly benefit through their existing exposure.

Tesla Inc. more than doubled its European car registrations in May, but China's BYD Co. has sold more vehicles in the region this year. Tesla registered 28,610 vehicles across Europe last month, a 107.9% jump and its fourth straight month of growth, according to the European Automobile Manufacturers’ Association. This figure ran about even with BYD, which logged around 27,641 registrations across its biggest European markets. The broader market share dynamics highlight the intensifying competition, as Chinese brands collectively took about 7.3% of the wider European market early in the year, more than three times Tesla’s share.

Sales Performance Comparison

BYD has registered about 128,900 vehicles in Europe through May, ahead of Tesla’s 118,068. BYD has outsold the American carmaker in most months of 2026. It is important to note that BYD’s tally includes plug-in hybrids, while Tesla sells only pure EVs. Tesla’s rebound is partly attributed to a weak base, as its European registrations fell roughly 27% in 2025. Factors such as a refreshed Model Y, Germany’s revived EV subsidy, and higher fuel prices have since pulled buyers back.

Market Outlook and Financials

Traders are pricing in specific expectations for the upcoming quarterly print. U.S. deliveries fell an estimated 15% in May as high borrowing costs weigh on demand. Polymarket currently puts around 80% odds on zero Fed rate cuts in 2026, keeping auto loans expensive and leaving Europe to carry second-quarter volume. Regarding delivery expectations, traders see Tesla’s Q2 deliveries most likely landing between 450,000 and 475,000, with the leading band at about 61%, up from 358,023 in the first quarter. The scenario for 475,000-plus deliveries is sitting at 15%.

Corporate Actions and Strategic Shifts

CEO Elon Musk exercised about 304 million options worth more than $110 billion from his reinstated 2018 pay package this month, lifting his stake to roughly 19.9%. Additionally, Tesla has raised its 2026 capital spending plan to about $25 billion from $20 billion to fund AI, robotaxi, and factory expansion. This strategic bet is expected to pressure free cash flow this year. Goldman Sachs noted this week that global EV adoption is accelerating fast enough to start denting oil demand by late 2027.
