# Why Tesla (TSLA) rose 1.95% on October 10, 2026

Tesla (TSLA) rose 1.95% on October 10, 2026 — Musk's Terafab chip plan puts Tesla in control of its supply.

## What happened

Tesla rose 3.6% after Elon Musk said Tesla will own and operate its Terafab chip project. The move reflects a shift toward direct control of chip production rather than dependence on outside foundries.

## Why it moved

Owning chip production can reduce supply risk and give Tesla more control over the silicon that powers its AI and autonomy roadmap.

## Why it matters

Tesla is a leading name in the Mag 7 Earnings Cycle, where mega-cap tech has been lifted by AI capex and earnings beats.

## What would break the thesis

If the Terafab project is delayed, underfunded, or still dependent on outside foundries, the thesis weakens. The gain could fade quickly if execution lags the announcement.
