Pershing Square new/increased position report: UBER — Bill Ackman's $2 Billion Uber Stake Has Gone Nowhere Fast. Time to Buy?Bill Ackman 新建仓/增持：UBER
English Section
On August 11, 2026, The Motley Fool published a report stating that Bill Ackman’s Pershing Square Capital has not made any changes to its $2 billion Uber Technologies (UBER) stake. This information is relevant for market participants tracking prominent institutional ownership moves, as Pershing Square’s public position adjustments often drive short-term trading volatility for associated stocks.
This signal currently relies solely on third-party media coverage, with no official SEC filings (such as Form 4 or updated 13F-HR) from Pershing Square confirming the specifics of this stake. Per Uber’s August 7, 2026 13F-HR summary covering positions as of December 31, 2025 — a quarter-end filing that does not reflect intraperiod trading activity — 82.5% of Uber’s float is held by 2,665 institutional investors, with total holdings valued at $139.8 billion. The filing shows 321 new positions, 1,402 increased positions, and 888 reduced positions in the quarter. Additionally, SEC Form 4 filings from July 20, 2026 show Uber insiders only completed small exempt trades and in-kind share transfers, with no large-scale position adjustments.
Follow-up markers
1. Official SEC filings from Pershing Square, such as Form 4 or updated 13F-HR disclosures, to confirm the validity and recent status of the $2 billion Uber stake;
2. Uber’s upcoming Q3 2026 earnings report, scheduled for November 3, 2026, which can provide contextual fundamental data to align with institutional ownership trends;
3. This signal does not confirm that the stake will be adjusted in the future, nor does it verify whether the position is a newly established or long-held holding.

2026年8月11日，The Motley Fool发布报道称，比尔·阿克曼（Bill Ackman）旗下的潘兴广场资本（Pershing Square）持有的优步（UBER）价值20亿美元的仓位未发生任何变动。这一信息对追踪知名机构持仓动向的市场参与者具有参考价值，因为潘兴广场的公开仓位调整常引发个股短期交易波动。
目前该信号仅来自第三方媒体报道，尚未有潘兴广场提交的SEC官方备案文件（如Form 4或13F持仓更新）确认该仓位的具体情况。根据优步2026年8月7日提交的截至2025年12月31日的13F-HR汇总文件（该文件仅披露季度末持仓，不反映期内交易变动），优步流通股的82.5%由2665家机构持有，总持仓规模达1398亿美元，当季新增持仓321家、增持1402家、减持888家。此外，2026年7月20日的SEC Form 4文件显示，优步内部人士仅完成少量豁免交易和实物股份划转，未出现大额持仓调整。
后续关注
1. 潘兴广场提交的SEC官方备案文件（如Form 4或13F持仓更新），以确认该20亿美元优步仓位的真实性及近期变动状态；
2. 优步将于2026年11月3日发布的2026年第三季度财报，可辅助验证与机构持仓相关的基本面逻辑；
3. 本次信号未证明该仓位存在后续调整计划，也未确认该持仓为新增持仓还是长期持有头寸。
