Tesla April 2026 Update: SpaceX Stake, UK Energy & Semi Ramp
Hey, Marcel here with my Tesla April 2026 update and overall Tesla investment progress. If you’ve been following my Tesla journey, I started buying TSLA shares back in November 2024 and kicked off documenting my long-term plan in March 2025 (check out my original post below). The strategy is simple: dollar-cost averaging £40 a week into Tesla (plus any spare cash), eyeing opportunistic dips, and holding strong through 2030+ as the ecosystem explodes with autonomy, AI, energy, and now even tighter links to SpaceX.

My Tesla Investment 2026: Portfolio Snapshot
My eToro dashboard shows the current reality Tesla April 2026 update. I’m continuing my steady £40 weekly DCA into TSLA, but the Tesla position is sitting at an unrealized loss of -$515.22 (-4.62%) with a net value of $10,638.29. Overall Cash & Holdings stand at $11,223.59 (note: this total includes my positions in NVIDIA, BTC, and ETH as well).
This experiment started back in November 2024. I’m still holding strong, adding on dips, and watching the full Tesla ecosystem (autonomy, energy, AI, and now deeper SpaceX ties) unfold.
Here’s the latest screenshot straight from my eToro dashboard – you can see the exact numbers from my Tesla April 2026 update, the 3-month performance chart, available cash, and current position details:
Cash & Holdings: $11,223.59 (includes NVIDIA, BTC & ETH)
Current TSLA price: $349.00
Tesla position net value: $10,638.29
Unrealized loss: -$515.22 ▼ (-4.62%)
I’m staying the course with my long-term hold until 2030+ — dollar-cost averaging through volatility has been the plan from day one. Crossing five figures while Tesla works through this phase is all part of the journey. Patient and still excited for what’s ahead.
Tesla News That’s Fueling My Bull Case
These real-world updates and broader catalysts are exactly what’s keeping me bullish long-term — here’s the breakdown:
Tesla Replaces xAI Investment with SpaceX Stake
Fresh off the press (FTC filings March 11, 2026): Tesla’s original $2 billion investment in xAI has officially rolled over into a minority equity stake (<1%) in SpaceX.
SpaceX acquired xAI last month in a blockbuster deal that created a combined $1.25 trillion entity focused on space-based AI data centers. Starlink + orbital compute could be next-level stuff.
This formally ties Tesla even deeper into Elon’s rocket/AI empire right before SpaceX’s planned mid-2026 IPO (rumored $1.5T+ valuation and potentially the biggest ever).
Analysts are buzzing about how this strengthens everything from Dojo training to Optimus robotics. Bullish signal for long-term TSLA holders like me!
Tesla Energy Goes Big in the UK
Electricity Supply License Secured! Tesla Energy Ventures just won full approval from Ofgem (UK regulator) on March 11, 2026 to supply electricity directly to homes and businesses across Great Britain.
No more relying solely on partners like Octopus Energy — Tesla can now launch its own “Tesla Electric” tariffs (100% renewable, powered by your Powerwall/Megapack).
Owners could soon earn monthly credits by joining Virtual Power Plants, feeding solar + battery energy back to the grid.
Add in the massive 1 GWh Megapack project in Scotland and Powerwall 3 rollout with its insane 97.5% efficiency inverter… Tesla Energy is quietly becoming a utility powerhouse in Europe.
This is the same playbook that’s already exploding in the US (record 46.7 GWh deployed last year). Diversified revenue streams = rocket fuel for the stock long-term.
SpaceX-Tesla Merger Rumors Before IPO?
Back in January/February the chatter was nonstop: Would SpaceX merge with Tesla (or xAI) ahead of its monster IPO?
Betting markets had it at 15-48% odds at one point. Instead, SpaceX folded xAI in first (which is why Tesla now owns that SpaceX slice).
But the speculation hasn’t died — some investors and analysts are still calling for a potential reverse merger into Tesla to consolidate the entire Musk cap table before SpaceX goes public.
Whether it happens pre-IPO or later, the financial ties are already tightening. For us retail holders, this could mean even bigger upside from shared AI, robotics, and energy tech. I’m here for it.
Tesla Semi – High-Volume Production
Tesla Semi is finally gearing up for high-volume production in 2026 at Giga Nevada. Elon Musk recently confirmed that the refreshed design will begin volume ramp this year, with meaningful deliveries expected throughout 2026 (initial estimates range from 5,000 to 15,000 units, with potential to scale significantly higher in 2027+).
The updated Semi features improved aerodynamics, structural upgrades inspired by the Cybertruck, 4680 battery cells for better energy density and cost reduction, and enhanced range and efficiency. Early feedback from fleet operators and test drivers has been very positive, highlighting major operating cost savings compared to traditional diesel trucks — often cited as 30-50% lower fuel and maintenance expenses over the truck’s lifetime.
This is a significant milestone for Tesla as it expands beyond passenger vehicles and autonomy into the massive Class 8 trucking market. A successful Semi ramp would add another diversified, high-margin revenue stream and further demonstrate Tesla’s ability to execute across multiple product lines. Long-term, it strengthens the bull case by proving Tesla isn’t just an EV or robotaxi company, but a broad energy + transportation platform.
Tesla Terafab: Massive In-House Chip Factory Plans
Tesla is taking a huge step toward chip independence with Terafab — a multi-billion dollar semiconductor fabrication project in Austin, Texas.
Announced in March 2026 as a joint effort between Tesla, SpaceX, and xAI (with Intel recently joining as a key partner), Terafab aims to build advanced chip manufacturing capacity at massive scale. The ambition is bold: producing hundreds of billions of custom AI and memory chips per year using cutting-edge 2nm technology, ultimately targeting 1 terawatt of compute power annually.
This project is critical for powering the next generation of Optimus robots, AI5 chips, full self-driving hardware, and even space-based AI data centers. By bringing chip design and fabrication in-house, Tesla reduces reliance on external suppliers and gains a major competitive edge in AI and robotics. Early construction signals are already visible at Giga Texas, and small-batch AI5 production is targeted for later in 2026.
Another powerful long-term catalyst for TSLA.

What’s Next for My Investment?
The Tesla story isn’t just cars anymore — it’s autonomy, energy, AI, and now direct SpaceX ownership. The recent pullback feels like classic volatility before the next leg up (robotaxi rollout + UK/Europe energy expansion + possible mega-merger news).
I’ve decided to increase my weekly contributions from £40 to £60 per week, while reducing intake from my other experiments. I strongly believe Tesla is currently the biggest catalyst for my overall portfolio.
Overall, this Tesla April 2026 update shows both the challenges and the exciting catalysts ahead. Elon’s vision of sustainable abundance is playing out in real time.
