July 2026 — Reporting around Tesla’s Q4 shareholder materials and Electrek/Electrive coverage maps the Semi charging build-out: 66 Megacharger sites identified across 15 US states (Texas 19, California 17), a partnership with Pilot Travel Centers — America’s largest truck-stop operator — with construction starting H1 2026 and first sites opening by summer, four to eight stalls per site at up to 1.2 MW per dispenser. Targets: 37 locations entering service during 2026, 46 stations operational by early 2027.

Why Europe should watch an American truck-stop deal. Because it answers the question “who builds megawatt charging at scale without an OEM alliance?” — a vehicle maker plus the incumbent truck-stop real estate, the same coalition logic as China’s swap build (sites + power + anchor demand) with a different cast. If the Pilot partnership produces reliable 1.2 MW charging on US interstates at truck-stop prices, it becomes the template every European CPO and every European truck-stop operator studies — and the pressure on Milence’s rollout pace increases correspondingly.

For European fleets, strictly a benchmark. The Semi itself remains US-only (no EU approval, no European service — our scorecard reflects it), so Megacharger’s relevance here is comparative: 1.2 MW per dispenser against Milence’s MCS at 2.8 MW combined at Antwerp, truck-stop amenity integration versus purpose-built hubs, and single-brand versus brand-agnostic access. Watch whether any European truck-stop group (Tank & Rast, Roadchef, Autogrill-type operators) announces a similar partnership — that announcement, when it comes, is the sign Europe’s megawatt map is about to fill far faster than the alliance-only scenario suggests.
