Rivian Autonomy+ vs Tesla FSD: Hands-Free ADAS Compared

A CNBC reporter drove Rivian’s Autonomy+ and Tesla’s Full Self-Driving (FSD, Supervised) across hundreds of miles to compare hands-free advanced driver-assistance systems (ADAS). Rivian’s Autonomy+ represents a major upgrade for the automaker—using a multimodal sensor stack (cameras, radars, planned lidar) and a new in-vehicle AI assistant—while Tesla’s FSD remains superior today at non-highway, point-to-point driving, handling traffic signals, roundabouts, exits and parking. Rivian plans point-to-point driving later in the year and has subscription and lifetime pricing options; Tesla and GM also offer subscription models. Safety and regulatory concerns persist: the NHTSA has escalated a probe into Tesla’s FSD after several crashes. The piece highlights differing technical approaches (vision-first vs multimodal sensor stacks) and the near-term roadmap for both companies.

Cisco stock drops despite earnings beat

Cisco reported fiscal Q4 results that beat expectations—adjusted EPS $1.22 vs $1.17 expected and revenue $17.25 billion (about an 18% year‑over‑year increase) vs $16.82 billion expected—and guided current‑quarter revenue to $18.0–$18.2 billion versus the $16.8 billion LSEG consensus. Hyperscalers placed roughly $4 billion of infrastructure orders in the quarter, bringing fiscal‑year hyperscaler orders to $9.3 billion; Cisco expects hyperscaler‑related revenue to rise to about $7.5 billion in fiscal 2027. Net income rose 51% year‑over‑year to $3.9 billion (97 cents a share). Despite the beat and above‑consensus guidance, shares fell about 9% on Aug. 13, 2026. Some analysts (Piper Sandler) called the guidance conservative while KeyBanc remained bullish; management described the period as a record quarter but urged prudence entering the new fiscal year.

Doximity Shares More Than Double After AI Remarks

Shares of Doximity more than doubled in premarket trading after CEO Jeffrey Tangney said the company’s new AI search product generates over ten times the revenue per search versus its cost. Doximity reported fiscal Q1 2027 revenue of $156.6 million and adjusted EBITDA of $74.8 million, both beating estimates, and raised its full-year revenue guidance by $6 million to a range of $671 million–$681 million. Analysts note that the updated guidance likely does not fully incorporate AI search revenue. Elevated short interest (about 17% of float) contributed to a rapid squeeze as positions were unwound. The stock surge followed comments on AI unit economics made on the company’s earnings call.
