Musk targets test chip by June 2027, mass production by Q3 2028

The timeline is the only substantive detail here, and it arrives without the specifics that would make it credible: no use case, no foundry partner, no capital commitment. That gap matters because chip programs are judged on fabrication relationships and funding as much as on schedules, and a target date without either is a statement of intent rather than a plan. For readers tracking semiconductor ambitions outside the established supply chain, the open question is whether the missing details surface before the test-chip milestone, since the mass-production date depends on them far more than on the calendar itself.
