That's pushed more investors toward assets that don't move in lockstep with public markets. Real estate, private credit, commodities, even direct oil and gas positions, are getting a second look.
Global alternative assets under management are projected to grow from $16.78 trillion in 2023 to $29.22 trillion by 2029, according to Preqin's 2024 forecast. This guide breaks down the top 10 alternative asset classes, how each works, and how to figure out which ones fit your situation.
Key Takeaways
- Core alternatives include real estate, private equity, commodities, energy development, and collectibles
- Most trade liquidity and regulation for genuine diversification beyond stocks and bonds
- Accredited investors can access direct oil & gas positions, private credit, and pre-IPO shares
- Match each class to your risk tolerance, time horizon, liquidity needs, and tax situation
Overview of Alternative Investments in the U.S. Market
Alternative investments are anything outside traditional stocks, bonds, and cash. Common examples include:
- Private equity
- Real estate
- Commodities
- Direct energy development
- Collectibles
These assets often move independently of public markets. That's valuable when stocks and bonds start falling together, which happened more than once in recent years.
A quick caveat: the $29.22 trillion figure above is global, not U.S.-specific. Still, it signals where institutional and private capital is heading. Preqin's strategy-level forecasts show private equity growing from $5.8 trillion to $12.0 trillion and private debt from $1.5 trillion to $2.6 trillion over the forecast window.
Below, we break down the 10 alternative asset classes U.S. investors most commonly encounter.
Top 10 Alternative Investment Asset Classes
These 10 asset classes were selected for historical return data, access for accredited and non-accredited investors, liquidity profile, and diversification value — spanning liquid public vehicles to long-hold private deals.
1. Private Equity
Private equity covers venture capital, growth capital, and buyouts. Investors provide capital to private companies in exchange for equity, typically with a 10-year-plus lock-up period before any exit, according to SEC investor guidance. Industry benchmarks report 11%-15% annualized returns, per CFA Institute — a published benchmark, not a guaranteed outcome for any specific fund.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Private Equity | Offering-specific | Very low (10+ years) | High |
2. Real Estate (Direct & Crowdfunded)
Where private equity locks capital for a decade, real estate spans both liquid and illiquid paths: publicly traded REITs and crowdfunded or direct deals.
- REITs: Exchange-listed and typically liquid, per the SEC
- Crowdfunding platforms: Fund specific properties, with hold periods commonly three to five years, per Forbes
Crowdfunded real estate shares can be locked up for a year or longer, with no guaranteed resale market.
Asset Type Typical Minimum Liquidity Risk Level Public REITs Cost of one share High Moderate Crowdfunded RE Platform-specific Low Moderate-High
3. Natural Gas & Oil Development
Direct working-interest positions let investors fund actual drilling projects rather than buying energy stocks. The standout feature is tax treatment: Intangible Drilling Costs (IDCs) — wages, fuel, and supplies tied to drilling — can be deducted against active income, including W-2 earnings and capital gains, under IRC Section 263(c) rules outlined in IRS Publication 5652. This is where PetroVybe operates. The Texas-based company develops natural gas liquids projects in Lavaca County (Gulf Coast Basin), with roughly 400 acquired legacy wells and 57-plus planned new wells across 58,000 acres. Partners have reported IDC deductions against active income of 91% in 2024 and 94% in 2025. The 10-year target is roughly 2.2x–5.8x MOIC with a ~26% IRR. Chief Geophysicist Michael Stamatedes’ documented 75.2% hit rate in well selection sits well above an industry peer average below 40%. Important context: these are forecasts, not guarantees. IDC eligibility requires a genuine working interest, and drilling carries real geological and market risk.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Direct O&G Working Interest | Offering-specific | Very low (long hold) | High (high tax efficiency) |
4. Private Credit
Unlike equity-style energy deals, private credit funds lend directly to businesses or consumers outside traditional banking. Investors earn interest income rather than equity appreciation. Preqin forecasts the sector reaching $2.8 trillion in AUM by 2028. Yields vary widely by vehicle — one fund reported an 11.4% net yield as of October 2024 per Morningstar, while a separate report showed a median unlisted BDC returning just 6.2% through three quarters of 2025, trailing its high-yield benchmark's 7.2%.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Private Credit | Fund-specific | Low | Moderate-High |
5. Commodities & Precious Metals
Gold, silver, oil, and agricultural commodities act as inflation hedges. Investors access them through physical ownership, ETFs, or futures. The S&P GSCI gained 40% in 2021 and 26% in 2022 during high-inflation years, per S&P Dow Jones Indices. But commodities aren't reliably positive — the same index averaged just 0.9% annualized during accommodative-rate periods since 1970, versus 10.5% when rates ran higher.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Commodities/Metals | Low (ETF share price) | High | Moderate |
6. Farmland
Fractional ownership platforms let investors earn income from crop leases plus land appreciation — without buying an entire farm. The NCREIF Farmland Index, a quarterly composite of private-market farmland, showed returns from 3.10% in Q4 2022 to -0.26% in Q3 2023. Results swing by quarter and property type, so treat any blanket 10% farmland claim with skepticism.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Farmland (fractional) | Platform-specific | Low | Moderate |
7. Fine Art & Collectibles
Fractional art platforms let investors buy shares of a single painting, sculpture, or rare item. Physical collectibles like wine and classic cars work similarly through specialty dealers. One major platform requires a $15,000 minimum and a three-to-ten-year hold before sale, according to a Columbia Journal of Law & the Arts analysis. Accurate valuation takes real expertise, with no public market price to reference.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Fine Art & Collectibles | Often $10K–$15K+ | Very low | High |
8. Cryptocurrency
Bitcoin, Ethereum, and other digital assets offer high upside but come with serious volatility. Forbes measured Bitcoin's annualized volatility at 35.48% as of August 2024. Morningstar found that even a modest 5% Bitcoin allocation contributed over 20% of total portfolio risk in one model. That's a scenario, not a universal rule, but it's a useful gut-check before sizing a crypto position.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Cryptocurrency | Low (exchange minimums) | High | Very high |
9. Pre-IPO / Private Company Shares
Platforms like EquityZen and Forge Global let accredited investors buy shares in VC-backed private companies before they go public. The Wall Street Journal reported minimums as low as $5,000 on some platforms as of March 2025. Shares can stay illiquid until a funding event, secondary sale, or IPO — and many startups never reach one.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| Pre-IPO Shares | As low as ~$5,000 | Very low | High |
10. Peer-to-Peer (P2P) Lending
Investors lend directly to individuals or small businesses through online platforms, earning interest income in return. Public return data is thinner here than in other categories. A 2012 Forbes report cited top-rated three-year loans with an expected default rate around 1.4% — a historical credit-risk reference, not a current return guarantee.
| Asset Type | Typical Minimum | Liquidity | Risk Level |
|---|---|---|---|
| P2P Lending | Platform-specific (often low) | Low–Moderate | Moderate-High |
How to Choose the Right Alternative Investment
The most common mistake? Chasing the highest advertised return without checking liquidity terms or investor accreditation requirements first.
Before committing capital, weigh:
- Risk tolerance – Can you hold an illiquid asset for 10 years, or do you need flexibility?
- Investment horizon – Match the asset’s lock-up period to your real timeline
- Minimum investment – Confirm the current minimum with the offering, not a secondhand source
- Tax treatment – Oil and gas IDC deductions, for example, can change your net return significantly
- Manager track record – Require third-party validation, not just marketing claims
Tax treatment can change net returns as much as the asset’s cash yield. PetroVybe partners, for example, can use IDC deductions to offset active income (including W2 wages) even though the investment itself is passive.
Conclusion
Adding 2-3 alternative asset classes can meaningfully reduce your portfolio's correlation to public markets. That's not a guarantee against loss, but it's a real diversification lever.
Before committing capital anywhere, check:
- Accreditation status
- Liquidity needs
- Tax situation
Then match those constraints to the asset class that actually fits.
If you're an accredited investor exploring tax-advantaged, passive income exposure, PetroVybe's natural gas development opportunities in the South Texas Gulf Coast Basin are worth a closer look.
Frequently Asked Questions
What are the most popular alternative investments?
Real estate, private equity, and commodities remain the most widely held alternatives among U.S. investors. Oil and gas development is a growing option for investors who want tax efficiency alongside diversification.
Where can I get a 10% return on my money?
Private credit, farmland, and oil and gas development have historically targeted or exceeded 10% in certain vehicles, though results vary by fund and year. Always check dated performance data rather than relying on generic claims.
What's the best investment for $10,000 right now?
Consider splitting between a low-minimum real estate crowdfunding platform and one higher-yield alternative like a commodities ETF. Note that direct oil and gas development and private credit typically require accredited status and higher minimums.
What are four examples of alternative investments?
Real estate, private equity, commodities, and oil and gas development are four common examples. Each offers different liquidity, risk, and tax profiles.
Are alternative investments only for accredited investors?
No. Some platforms, like REIT crowdfunding, are open to all investors, but others, including private credit and direct oil and gas development, require accreditation. SEC accreditation generally means $1 million net worth (excluding your home) or $200,000+ individual income ($300,000 joint).
How much of my portfolio should be in alternative investments?
There's no universal rule. Institutional endowments like Yale have allocated close to 50%, but that's not a retail benchmark. Base your allocation on your own liquidity needs, risk capacity, and tax situation.
