Public

The $1.2 Billion Pre-IPO Deep Dive — an "agentic brokerage" with no disclosed revenue, a five-year-old price tag, a reversed no-PFOF pledge, and nothing on EDGAR but Form Ds.

Executive Thesis

Public is the most product-ambitious mid-tier US retail brokerage — stocks, options, fractional corporate bonds, Treasuries, crypto IRAs, alternatives and, since March 2026, AI agents that trade on a member's behalf. It is also the most opaque: the last disclosed valuation is the $1.2B Series D of February 2021, the December 2024 $135M Series D-2 carried no price, revenue has never been reported, and the only audited numbers are a broker-dealer subsidiary with $9.1M of equity. The "no PFOF" brand that defined the 2021 story has been reversed in the fine print, FINRA has fined the firm twice, and the UK expansion lasted eight months. There is no reported IPO process. This is a watch-the-comps name, not a watch-the-filing name — and the comps say a listing would be benchmarked against Webull, not Robinhood.

Public launched in 2019 as an investing social network — follow other investors, see their portfolios, learn in public — and rode the 2021 retail wave to a $1.2B Series D three weeks after the GameStop squeeze, famously dropping payment for order flow in favor of tipping the same month. Since then the company has re-positioned twice: in 2025 to a "platform for long-term, affluent investors" (the social feed was sunset in June 2025), and in 2026 to the "world's first Agentic Brokerage," with AI agents that monitor, rebalance and execute on a member's instructions.

The moat question is where the thesis gets hard. Public's strengths are real but replicable:

3 · Financials & What EDGAR Actually Shows

No revenue, no AUM, no funded-account count — but an audited subsidiary

Public discloses adjectives, not numbers: "scaled AUM into the billions," "attracts billions in deposits annually," "gross profit per user grows every quarter," "core brokerage business is profitable with over 10 significant revenue streams" (all December 2024). The last hard operating metric was 3M+ members in November 2022; funded accounts were said to have "more than doubled" in 2022 but never quantified.

Disclosed funding rounds · 2019 → 2024
USD millions · 5 rounds · dashed = the $30M debt tranche of the Series D-2 · valuation disclosed only at Series D
$250M $200M $150M $100M $50M $0 $7M Series A · 2019 $15M Series B · 2020 $65M Series C · Dec 2020 $220M Series D · Feb 2021 $1.2B post-money $105M + $30M Series D-2 · Dec 2024 valuation not disclosed

What EDGAR does show. The broker-dealer, Open to the Public Investing, Inc. (CIK 0001253489), files an annual audited FOCUS report. The public portion of the FY2024 statement of financial condition — the newest whose PDF is machine-readable — reads as follows:

Line item (Dec 31, 2024)USDRead-through
Total assets$75.5MOf which $63.8M is fractional shares held for users (pass-through)
Additional paid-in capital$41.1MParent capital pushed down into the BD since inception
Accumulated deficit($31.9M)Cumulative BD-level losses; federal NOLs ~$26.8M
Stockholder's equity$9.1MThe regulated entity is small
Net capital$7.8Mvs $250K minimum — comfortably compliant
Deferred tax asset valuation allowance$7.4MManagement does not expect to use the NOLs soon — not a profitability signal

Two caveats cut both ways. The BD is a subsidiary, not the group: crypto (zerohash), Treasuries (Jiko), cash yield, subscriptions and advisory fees sit in other entities or the parent, so the $31.9M deficit understates neither nor proves group losses. But the full valuation allowance against the NOLs is an auditor-reviewed statement that the regulated business is not expected to be reliably profitable near-term — which sits awkwardly next to "core brokerage business is profitable." An S-1 would reconcile the two. There is none.

4 · IPO Status & Timeline

No filing, no bankers reported, no timeline — and a price that is five years old

We checked EDGAR directly. Public Holdings, Inc. (CIK 0001723653, formerly TapX Trading & Analytics) has exactly four filings, all Form D, the last dated December 16, 2020. There is no S-1, no public DRS — and notably no Form D for the December 2024 round either. No credible outlet has reported banker mandates, a confidential filing, or an IPO timeline in 2025–2026. The only on-record comment is co-CEO Leif Abraham's in May 2023: "too early to determine any exit timeline," with a stated preference for strategic investors who "remain invested through an IPO" and no interest in a sale.

⚡ Reading the Setup
A quiet D-2 is the opposite of a crossover round

The critical nuance: the December 2024 raise was led by the existing lead (Accel, which "has led or co-led every funding round since 2019"), included $30M of debt, and was announced without a valuation — the pattern of an insider-supported extension, not a pre-IPO mark. Forge carries an unverified $983M "Series D-3" valuation from March 2025; if real, that is an ~18% step-down from 2021.

  • Secondary quotes in August 2026 — $5.73 (Hiive) and $6.41 (Nasdaq Private Market, −23% over its window) per share — cannot be converted to a valuation because no round price per share is public, but the direction is down.
  • Order books are thin: eight live orders on one venue, three asks on another. There is no tender program relieving employee liquidity.
  • The CFO's listing experience is a SPAC (MoneyLion, 2021), not a traditional IPO.
  • The company's 2026 "IPO pre-access" and Private Company Pages features are products for members — not signals about its own listing.

Base case: no listing before 2028; the next event is a priced round or a strategic sale. Bull case: a 2027 IPO if the agentic pivot produces a disclosable revenue number above Webull's growth rate. Bear case: a recapitalisation or acquisition by a larger brokerage or bank below the 2021 mark.

5 · Competitive Landscape

The listed retail-brokerage set now has three fresh public comps

RobinhoodHOOD$4.5B27.0M$324BNeutral

CoinbaseCOIN$7.2Bn/dn/dStrong Buy
SoFi InvestSOFIsegment n/d10.9M members (group)n/dSell

Signals are the QL engine's read as of August 21, 2026. The competitive picture has changed materially since Public's last priced round: Webull listed via SPAC in April 2025 and eToro IPO'd in May 2025, so a Public listing would now be benchmarked against two mid-cap, recently-public peers with disclosed numbers — not against Robinhood's $86B. Webull is the closest analogue: 5M funded accounts, $571M revenue growing 46%, a $4.6B market cap. Public has never said how many of its 3M+ members are funded.

Market cap per customer account — listed brokerages vs Public
USD · market caps from the QL universe (Aug 21 2026) ÷ latest reported funded accounts · Public = $1.2B ÷ 3M members (members ≠ funded; an upper bound on per-funded-account value is higher)
$8,000 $6,000 $4,000 $2,000 $0 ~$7,900 Interactive Brokers IBKR · $41B ÷ 5.19M ~$3,190 Robinhood HOOD · $86B ÷ 27.0M ~$920 Webull BULL · $4.6B ÷ 5.0M ~$400 Public $1.2B ÷ 3M members (2022)
"The competitor that matters is not Robinhood. It is Webull — a freshly listed, 5-million-account, $571M-revenue brokerage that the market values at $4.6B and the QL engine currently reads as a Sell. That is the multiple Public's bankers would have to argue against."

6 · The PFOF Reversal & the Regulatory Record

The 2021 brand promise versus the 2026 fee schedule

⚡ What Public-Market Diligence Will Find First
"No PFOF" is gone, and FINRA has been here twice

On February 1, 2021 Public dropped equity payment for order flow and replaced it with optional tipping — the defining move of the brand. Its current Rule 606/607 disclosure routes listed stocks and ETFs to a default "wholesale route" from which "we receive payment for order flow"; the non-PFOF "smart" and "lit exchanges only" routes cost $0.003 per share. Options, launched January 2024, are PFOF-funded, with the company keeping 50–84% and rebating $0.06–$0.18 per contract to the customer. We could not find a primary source dating the equity-PFOF reinstatement; it was never announced the way the 2021 removal was.

The enforcement record of Open to the Public Investing, Inc.:

  • December 2023 — FINRA, fully-paid securities lending. One of four firms (with M1, SoFi Securities, SogoTrade) ordered to pay a combined $2.6M including over $1M of restitution for auto-enrolling every new customer in FPSL with no appropriateness criteria and disclosures that misrepresented the "loan fee" customers would receive.
  • May 27, 2025 — FINRA AWC, influencer marketing. Censure, $350,000 fine and an undertaking. From January 2020 to September 2022 the firm paid 110 influencers per post or per funded account, uncapped; more than 23,000 accounts were opened through their links; posts were "not fair and balanced," claimed "commission free" without fee disclosure, and were often not labeled as advertisements. Communications were not reviewed or retained until March 2023.
  • No SEC enforcement action against the parent, the BD, or Public Advisors was found.

Why it matters for the IPO: neither fine is large. But together with the UK closure (launched July 2023, shut February 2024 — "better to focus on US business for now") and the influencer-driven growth they describe, they define the diligence narrative an S-1 would have to rebut: a company that has changed its model, its market and its monetization three times in five years.

Without a revenue number, the honest approach is to ask what the 2021 mark requires. At Webull's ~8.1× the $1.2B valuation needs ~$150M of revenue; at eToro's ~2.9× it needs ~$410M. Public's "10+ revenue streams" on an older, wealthier base make the lower bar plausible — which is why the secondary market has not collapsed the name, only drifted it. Fair-value triangulation under explicit assumptions:

Bottom Line

Public has built a genuinely broad product — seven asset classes, an older and wealthier cohort than Robinhood's, and the first live AI agents in a US brokerage — and it has done so with a fraction of its rivals' capital. What it has not done is tell anyone what it earns. The last price is five years old, the last round was unpriced, the secondary market is drifting down, and EDGAR holds nothing but Form Ds. The no-PFOF story that justified the 2021 premium has been quietly reversed, and FINRA has written the diligence memo twice. Webull's listing set the benchmark: ~8× revenue and ~$920 per funded account for a growing, profitable mid-tier brokerage. Public's 2021 mark needs ~$150M of revenue to hold at that multiple — plausible, but unproven. For growth portfolios this is a watch-the-comps name, not a watch-the-filing name: there is no IPO to position for until the company prices a round or discloses a number.
