What changed in Q2 2026?

Last quarter = Q2 2026 (period of report 2026-06-30) versus prior Q1 2026 (2026-03-31). Figures are reported 13F values (USD) as filed — delayed snapshots, not live prices.

Here is the story in one breath: more 13F filers (890 vs 779), and the aggregate reported 13F value rose (about $20.78B from about $14.00B). Total disclosed shares also moved to about 125,994,048 from about 105,967,679. Hedge-style* holders numbered 13 in Q2 2026 versus 12 in Q1 2026. On the full 13F tape, 217 managers entered and 106 exited (hedge-style* enter/exit: 4 / 3).

Status mix across the QoQ tape (996 manager rows including exits): 217 ENTERED, 106 EXITED, 344 INCREASED, 236 DECREASED, 93 UNCHANGED.

Reporting-entity note: several Vanguard-affiliated names appear as ENTERED under new CIKs in Q2 2026 (for example VANGUARD PORTFOLIO MANAGEMENT LLC ($1.20B), VANGUARD CAPITAL MANAGEMENT LLC ($1.05B), VANGUARD FIDUCIARY TRUST CO ($147.17M), VANGUARD ASSET MANAGEMENT, Ltd ($43.64M)). That is a 13F filer / CIK event in this tape — not automatically the same thing as “Vanguard never owned RDDT before.” Read it as new reporting entities showing up for this CUSIP in the QoQ join.

How to read reported 13F value. The dollar amounts below are each position’s reported 13F value (USD) from the manager’s filing. Values can move with the stock’s quarter-end price even when share counts fall. They are delayed snapshots (managers generally file within 45 days after quarter-end), not a live ownership feed. For context only: Q2 2026 aggregate reported value is roughly 89.3% of the ~$23.3B market-cap figure used on this page — that is not the same as “% of float owned,” and summing 13F positions is not a precise ownership stake.

Company AI overview — Reddit, Inc.

Reddit, Inc. operates the Reddit community platform — interest-based forums (“subreddits”) where people share links, posts, and discussion. Principal executive offices: 303 2nd Street, South Tower, 5th Floor, San Francisco, California 94107. Class A common stock trades on the NYSE as RDDT (IPO March 2024). Sources: investor.redditinc.com; redditinc.com; SEC Form 10-K (CIK 0001713445).

Short history. Reddit launched in 2005 and incorporated as a Delaware corporation in 2011. The public listing in 2024 put a long-running internet community business on the NYSE under ticker RDDT.

Business model & revenue streams. Reddit’s mission statement on IR pages is to empower communities and make their knowledge accessible. Monetization is primarily digital advertising and related platform products (plus other commercial programs disclosed in filings). User-generated communities and volunteer moderation are core to the product, not a side feature.

Competition. Other social / content platforms, forums, and discovery apps compete for attention and ad budgets. Reddit’s differentiation is interest-graph communities and long-form discussion — still fighting the same attention economy as everyone else.

Moat (humble take). Network effects inside large subreddits and brand recognition can be sticky. Moderation quality, trust & safety, and advertiser demand still drive outcomes.

Challenges & opportunities. Challenges include ad-cycle sensitivity, platform competition, and scaling trust & safety. Opportunities track user growth, ad-product improvements, and licensing / data partnerships where disclosed by the company.

Recent update (company IR). As of 30 Jun 2026, Reddit’s IR site highlighted roughly 130M+ daily active uniques, 514M+ weekly active uniques, 100K+ active communities, and 26B+ posts & comments (investor.redditinc.com). For GAAP results, use the latest 10-Q / 10-K on EDGAR and the TradingView financials widget above.

* Hedge-style footnote. QuantyFight uses a proprietary "hedge-style" label / classification based on portfolio characteristics such as portfolio concentration and number of reported holdings. It is an analytical classification and does not indicate the fund's official legal or regulatory classification.
13F limitations. Form 13F covers U.S. equity long positions above disclosure thresholds for managers that file. It omits most shorts, derivatives detail, non-13F securities, and intra-quarter trading. Filings arrive weeks after quarter-end. Holder lists on this page reflect 13F coverage for Reddit, Inc. (RDDT) as compiled for QuantyFight’s stock view — not a claim that every global holder is listed.
