An architect of California’s billionaire tax says he’s an ‘enthusiastic capitalist,’ but the system ‘doesn’t seem to be working.’ He’s got a plan

Brian Galle, architect of California’s proposed “billionaires tax” and author of How to Tax The Ultrarich, argues for federal reforms (the FAST plan) that tax wealthy holders when assets are sold but impose retroactive, economically-accurate interest to eliminate the benefit of deferring realization; the proposal targets ultrawealthy households (roughly >$30M) and replaces the estate/gift tax with an inheritance/carryover-basis regime with extra interest charges. The California bill—framed as a response to roughly a $100 billion state funding gap—reignited debate over the “buy-borrow-die” avoidance model and follows legal uncertainty after the Supreme Court’s Moore decision avoided endorsing taxes on unrealized gains. For investors, the proposals raise policy risk around concentrated, privately held wealth and estate planning strategies, though Galle and some analysts argue valuation and loophole issues are solvable.

Analysis

Market structure: A credible state-level wealth tax and a plausible federal FAST proposal shift economic rents from ultra-high-net-worth individuals (UHNWIs) toward tax planning, lending and appraisal service providers. Winners: asset managers with advisory fee capture (BLK, TROW, SCHW), private-credit lenders (ARES) and litigation/appraisal boutiques; losers: discretionary luxury consumption, high-end art dealers and illiquid private company valuations where forced or accelerated realizations compress prices by an estimated 5–15% if selling pressure materializes over 12–24 months.

Risk assessment: Primary tail risks are a Supreme Court injunction against unrealized-gains mechanisms, large capital flight from CA and aggressive avoidance via re-domiciliation—each could reverse price moves in 3–18 months. Near-term (days–weeks) market impact is muted; short-term (3–6 months) volatility rises around legislative milestones; long-term (1–3 years) structural shifts in private markets and municipal finance depend on revenue realization and enforcement design. Key catalysts: CA legislative votes (next 3–6 months), CBO/CRA revenue estimates (60–120 days), and appellate rulings (12–36 months).

trade implications: Positioning should favor providers of leverage and tax advice: establish 1–2% long positions in ARES and BLK with 12–18 month horizons, while hedging through long-put protection on luxury discretionary names (RH, LVMUY) sized 0.5–1% to reflect a 5–15% downside risk. Buy volatility around vote dates via 45–75 day SPY straddles (target 20–30% IV expansion) to capture event-driven uncertainty.

contrarian angles: Consensus assumes billionaires will simply borrow to pay taxes; FAST’s interest-capture mechanism and removal of step-up basis could force realizations and materially reprice private stakes—an underappreciated source of supply. Historical parallels (France’s wealth tax reversals) suggest legal and avoidance boomerangs, so overweight regulatory-lobby beneficiaries rather than pure luxury shorts; unintended consequence: increased demand for private credit could compress yields by 50–150bps, benefiting ARES-like players.

Key Decisions for Investors

• Establish a 1.5% long position in Ares Management (ARES) over a 12–18 month horizon to capture higher private-credit origination volumes if UHNWIs borrow more; use a 12% stop-loss and trim at +25%.
• Build a 1–2% long position split between BlackRock (BLK) and T. Rowe Price (TROW) to capture advisory and rebalancing fees; hold 6–12 months and take profits on 15–20% upside tied to legislative progress (e.g., bill passing committee within 90 days).
• Initiate a 0.75–1% protective short or buy 3‑6 month 10–15% OTM put spreads on luxury/discretionary names (RH, LVMUY) to hedge 5–15% downside risk from reduced UHNW consumption; roll or exit after 6 months or post-enactment clarity.
• Buy 45–75 day at-the-money SPY straddles sized to 0.5–1% of portfolio ahead of key CA legislative votes or CBO score releases (expected within 30–120 days) to monetize event-driven volatility; sell into IV spikes >30% above current levels.
