AUR enters the week with a striking divergence: options traders are the most bullish in the past year, yet one of the stock's most prominent institutional backers just made its largest-ever exit from the register.
The options signal is the standout this week. Call demand has overwhelmed puts to a degree rarely seen for this name — the put/call ratio dropped to 0.14, more than 2.5 standard deviations below its 20-day average of 0.19, and within a whisker of the 52-week low of 0.12. That is the least defensive options posture Aurora has carried all year, pointing to unusually concentrated bullish positioning in the derivatives market. The move is sharp enough to warrant attention on its own, but it sits against a backdrop where the single largest newsflow item is unambiguously negative.
Uber Technologies has been trimming its Aurora stake aggressively. On September 15, Uber filed an SEC Form 4 disclosing the discretionary sale of 29.4 million shares at $6.21, worth roughly $182 million. That followed an even larger disposal on August 17 — 72 million shares at $6.55, totalling $472 million. Combined, Uber shed over 101 million shares in roughly four weeks, cutting its declared stake from 10.9% to 9.2% per its most recent 13D/A filed September 17. Uber remains an activist filer under Schedule 13D, meaning these disclosures are closely watched; as the standard caveat applies, stakes are as-last-disclosed and a holder can fall below 5% without a further filing. The scale of the selling — approaching $650 million in declared value over the period — is the dominant ownership story for AUR right now.
Short interest is elevated but not accelerating, which gives the bulls some room. Aurora's short interest is at 12.3% of free float — genuinely high in absolute terms, but the trend has been marginally lower, down about 1% over the past month and fractionally softer on the week. Borrow conditions are relaxed: cost to borrow has fallen 14% over the month to just under 0.50%, and availability is running at 263%, well clear of the tighter end of the range. The 52-week tightest reading was 160%, so the lending pool is comfortable. The ORTEX short score of 66.7 is elevated in percentile terms — ranking in just the 7th percentile for short score, meaning significant short pressure relative to the universe — but has eased from its mid-week high of 69.5 hit on September 16, when short interest briefly spiked before retreating.
The Street is constructive but split across a wide target range. Morgan Stanley's Ravi Shanker raised his target to $18 on September 11 while holding an Overweight — a bellwether move that lifted the consensus mean toward $11.55, roughly 79% above the current price of $6.46. Craig-Hallum initiated at $18 in June and Needham holds a $13 Buy. Against those, Goldman Sachs maintains Neutral with a $5 target and TD Cowen holds at $7, reflecting genuine disagreement about near-term path. The bull case centres on Aurora's second-generation autonomous trucking kit — hardware costs reportedly down more than 50% — and a target of reaching gross profit positivity by late 2026. Bears point to revenue that barely registered ($1 million in Q3 2025), heavy operating spend running above $200 million per quarter, and safety concerns that could slow commercial adoption. EPS momentum factor scores of 17 and 14 over 30- and 90-day windows confirm the forward estimate revisions trend remains weak, making the $11.55 consensus mean a valuation call rather than an earnings-driven one.
Institutional flows add nuance to the Uber exit. T. Rowe Price remains the largest institutional holder with 302 million shares (15.1% of shares outstanding), and added 7 million shares through to September 1. Capital Research and Management added a substantial 78 million shares through August 31, now holding 8% of the company. Morgan Stanley Investment Management added 22 million shares through July. These are meaningful accumulation signals from long-only investors that partially offset Uber's distribution. The co-founders — CEO Christopher Urmson with 7.3% and co-founder Sterling Anderson with 2.2% — remain on the register with no change in position per the most recent SEC disclosures, suggesting management conviction has not wavered.
The next earnings date is October 28. The most recent print in late July produced a muted one-day move of roughly 0.5%, though the stock gained nearly 8% over the five sessions that followed. What to watch in the run-up: whether Uber files another 13D/A reflecting further selling, whether the unusual call-side skew in options holds or reverses as the event draws closer, and whether any operational update on commercial trucking deployments shifts the fundamental narrative ahead of what is shaping up as a pivotal gross-margin inflection quarter.
