Independent Verdict
MYDA Capital L.P. is a verifiable New York hedge fund with a long SEC filing history, an identifiable general partner, a separately registered investment adviser and public securities ownership records that allow the MYDA structure to be independently cross-checked from several directions.
The fund operates under CIK 0001500949 and filed its latest Form D/A on September 17, 2026. That filing reports an indefinite offering, approximately $63,620,542 in cumulative securities sold, 118 investors and a $250,000 minimum investment. The fund relies on Rule 506(b) and Section 3(c)(1), is classified as a hedge fund, and has been offering interests since September 6, 2010.
The Form D identifies MYDA Capital GP LLC as the fund's general partner and Jason Lieber as Managing Member of that general partner. The latest filing also states that the total amount sold includes investments made through an affiliated fund, MYDA Capital Ltd., which invests exclusively in MYDA Capital L.P. This is an important structural point because the $63.62 million figure is not necessarily the amount subscribed directly by investors into the U.S. partnership alone.
The strongest independent evidence comes from outside the Form D. MYDA Advisors LLC is separately listed in the SEC Investment Adviser Public Disclosure system as an SEC-registered investment adviser under CRD 168658 and SEC file number 801-108431. Its 2026 Form ADV data reports approximately $821.15 million in regulatory assets under management, all on a discretionary basis, with five private funds and approximately $806 million in private-fund gross asset value. Those figures relate to the adviser's broader business and should not be confused with MYDA Capital L.P.'s $63.62 million cumulative Form D sales.

The MYDA Structure Can Be Verified Across Multiple SEC Records
MYDA Capital L.P. is not an isolated filing. The same entities and individuals appear across Form D, Form ADV, Schedule 13G and other SEC ownership disclosures, creating a much stronger due-diligence trail than a single private-fund notice would provide.
The September 2026 Form D identifies MYDA Capital GP LLC as general partner and Jason Lieber as Managing Member. The principal address is 1067 Broadway in Woodmere, New York, with telephone number 516-400-9757. MYDA Advisors LLC separately appears in the SEC's Investment Adviser Public Disclosure system as an SEC-registered investment adviser, effective since September 2016, under CRD 168658 and SEC file number 801-108431.
MYDA's official website at mydacapital.com is unusually minimal, showing primarily MYDA Advisors LLC and a contact form rather than publishing detailed portfolio, team or fund information. For this issuer, that means the regulatory record is actually more informative than the public-facing website. This is an important distinction: the sparse website should not be interpreted as absence of a regulated adviser when SEC IAPD records directly confirm the adviser's registration.
MYDA Advisors' March 2026 Form ADV-derived data reports approximately $821.15 million in regulatory assets under management, seven discretionary accounts, eight employees and five private funds with approximately $806 million in gross asset value. The adviser reports portfolio management for pooled investment vehicles and compensation through both asset-based and performance-based fees.
These numbers provide manager-level scale, but they must remain separate from MYDA Capital L.P. itself. The hedge fund's Form D cumulative sales are approximately $63.62 million, while the adviser manages substantially more capital across multiple funds and accounts.
MYDA Capital Is Part of a Broader Fund Family
The regulatory record also identifies several related MYDA vehicles. MYDA Advantage, L.P. has a separate Form D history and uses the same MYDA Capital GP LLC, Jason Lieber and Woodmere address. MYDA Short Term Strategy, LP also appears in SEC filings under CIK 0001763758, again using MYDA Capital GP LLC as general partner and Jason Lieber as a related person.
MYDA SPAC Select, Ltd., a Cayman Islands vehicle, has also historically identified MYDA Advisors LLC as its investment manager. This shows that the broader MYDA platform has operated more than one strategy and has used both U.S. and offshore structures.
The September 2026 MYDA Capital L.P. amendment adds another useful structural detail: the filing states that total securities sold include sales to MYDA Capital Ltd., an affiliated fund that invests exclusively in MYDA Capital L.P. That language indicates a feeder relationship and means investors should understand whether they hold the U.S. fund directly or invest through an affiliated vehicle.
This is exactly the type of detail that can be lost if a review only copies the headline Form D number.
The $63.62M Sold Figure Needs the Right Context
The latest filing reports $63,620,542 in cumulative securities sold to 118 investors, with an indefinite amount remaining available for sale. The minimum investment is $250,000.
This is not a new 2026 launch. The filing gives a first sale date of September 6, 2010, meaning the offering has been active for roughly sixteen years. The 2026 Form D/A is therefore an amendment to a mature private fund rather than an initial fundraising notice.
The investor count and cumulative amount sold should also not be treated as current NAV. Form D sales measure securities sold over the life of the offering; they do not automatically reflect withdrawals, gains, losses, distributions or the present value of the fund.
The filing explicitly notes that MYDA Capital GP LLC and/or its affiliates receive customary management fees and/or incentive allocations as described in the confidential private placement memorandum. This is consistent with MYDA Advisors' broader Form ADV disclosure that compensation can include both asset-based and performance-based fees.
Public Equity Ownership Filings Add an Unusual Layer of Transparency
One of the most distinctive features of the MYDA ecosystem is that parts of its public-equity activity can be independently observed through Schedule 13G filings.
For example, 2026 SEC filings involving Energous Corporation identify MYDA Advisors LLC, MYDA Capital GP LLC, MYDA Advantage LP and Jason Lieber together as reporting persons. An April 2026 amendment reported shared voting and dispositive power over 180,000 Energous shares, representing approximately 3.27% of the company at that filing date.
Other SEC ownership filings show the same MYDA entities connected with SmartKem, Inc. These filings are valuable because they independently confirm that MYDA Advisors, MYDA Capital GP, MYDA Advantage and Jason Lieber operate together within an investment-management structure and hold reportable positions in publicly traded securities.
This should not be interpreted as proof that MYDA Capital L.P. itself owned every reported position. Some filings specifically identify MYDA Advantage LP as the fund holding the securities. The useful conclusion is narrower: the broader MYDA platform has a demonstrable public-equity investment footprint that can be independently verified through SEC ownership disclosures.
What We Think
MYDA Capital L.P. has a substantially stronger evidence trail than its minimal website might initially suggest. The fund has a long Form D history dating back to 2010, a clearly identified general partner, a named managing member, a separately SEC-registered investment adviser, related private funds and public Schedule 13G ownership filings that repeatedly connect MYDA Advisors, MYDA Capital GP and Jason Lieber.
The main diligence issue is therefore not entity verification. The more important questions concern strategy, fund-level performance and how the different MYDA vehicles interact. MYDA Advisors' Form ADV indicates a much larger asset base than MYDA Capital L.P.'s cumulative Form D sales, which means an investor should not assume that the hedge fund represents the adviser's entire investment business.
Investors should also determine how MYDA Capital Ltd. operates as an affiliated feeder, whether MYDA Advantage and MYDA Short Term Strategy use related or distinct investment strategies, how opportunities are allocated across the funds and whether cross-fund ownership or trading creates potential conflicts.
The public Schedule 13G filings provide useful examples of MYDA's investment activity, but current portfolio exposure cannot be reconstructed from those filings alone. A 13G is triggered only in specific ownership circumstances and does not provide a complete fund portfolio.
Risk Factors
The primary risks include hedge-fund strategy risk, public-equity volatility, concentration, liquidity, performance-fee incentives and multi-fund allocation complexity. MYDA's public ownership filings show that the broader platform can hold meaningful positions in smaller public companies, which may experience substantial price volatility and thinner trading liquidity.
The existence of several MYDA-managed vehicles also creates a need to understand allocation policy. Investors should confirm how the adviser decides whether an opportunity belongs in MYDA Capital, MYDA Advantage, MYDA Short Term Strategy or another managed account, and whether different vehicles trade the same securities.
The $250,000 minimum, Rule 506(b) exemption and Section 3(c)(1) structure reinforce that this is a private investment product rather than a retail mutual fund. Investors should review liquidity restrictions, redemption terms, side pockets if applicable, valuation policies and the exact management and incentive fee structure before investing.
Form D Is Not SEC Approval
The Form D filing confirms an exempt securities offering. MYDA Advisors' IAPD record confirms that the adviser is SEC registered. Neither fact means the SEC has approved MYDA Capital L.P., endorsed its strategy, verified its performance or guaranteed investor returns.
Final Assessment
MYDA Capital L.P. is a verifiable New York hedge fund operating under SEC CIK 0001500949 with a regulatory history extending back to 2010. Its latest September 17, 2026 Form D/A reports approximately $63.62 million in cumulative securities sold, 118 investors, a $250,000 minimum commitment, Rule 506(b) and Section 3(c)(1).
The fund's regulatory structure can be independently verified through several sources. MYDA Capital GP LLC is the general partner, Jason Lieber is its Managing Member, and MYDA Advisors LLC is a separately SEC-registered investment adviser under CRD 168658 and SEC file number 801-108431. The adviser's 2026 Form ADV data reports approximately $821.15 million in regulatory assets under management and five private funds.
The strongest independent finding is the breadth of the regulatory footprint. MYDA is not represented only by one Form D. The same adviser, general partner and Jason Lieber also appear across MYDA Advantage, MYDA Short Term Strategy, MYDA SPAC Select and public Schedule 13G filings involving companies such as Energous and SmartKem.
For investors, the key next step is to move beyond entity verification and examine the actual fund economics: current NAV, historical returns, volatility, liquidity, redemption terms, management fee, incentive allocation, current portfolio, concentration limits, use of leverage and the allocation of investment opportunities across MYDA-managed vehicles.
The filing also confirms that part of the reported $63.62 million sold includes investment through affiliated MYDA Capital Ltd., so investors should understand the feeder structure rather than treating every dollar as a direct subscription into the domestic partnership.
SEC Form D is a notice filing for an exempt securities offering. It does not constitute SEC approval, endorsement of MYDA Capital, verification of portfolio performance or a guarantee of investor returns.
