Tesla posted its best second quarter ever, then watched $214.5 billion vanish in a single session on Wall Street.
Shares slid 14.5 percent to $319.69 by Thursday's close after the Q2 earnings report.
According to the Wall Street Journal, that's the worst single day in Tesla's history, and the sum lost exceeds the entire current market cap of every other automaker.
Record Deliveries Driven by Model 3 and Model Y
Across April, May, and June, Tesla produced 451,758 vehicles and delivered 480,126 units.
This represents the best Q2 result in the company's history, up 25 percent from the same quarter last year.
The increase followed consecutive year-over-year declines in quarterly deliveries.
Of the 480,126 deliveries, 467,762 were Model 3 and Model Y, with the remaining 12,364 split across the discontinued Model S and X, the Cybertruck, and Semi.
Strong sales were bolstered by a surge in demand across several European countries, including Portugal, Slovenia, and Lithuania, as well as strong results across Asia and the Pacific, such as in Australia, South Korea, Japan, Taiwan, and Thailand.
The new three-row Model Y L likely played a role, although Tesla hasn't disclosed how many it shipped and delivered during the quarter.
Higher gas prices tied to the US war in Iran also pushed more European buyers toward EVs in the first half.
Financials: Revenue Up, Profits Down
Tesla's total revenue rose 26 percent from a year earlier to $28.24 billion, beating estimates.
Of this, $20.52 billion came from the automotive segment, a 23 percent jump.
The energy business brought in $3.14 billion, up 13 percent, while services and other revenue rose 50 percent to $4.58 billion.
Despite stronger revenue, gross margin dropped from 17.2 percent to 16.8 percent, while GAAP net income fell 5 percent to $1.11 billion.
Analysts had expected a 19.4 percent gross margin, per StreetAccount.
Several factors contributed to the profit decline.
Operating expenses climbed faster than revenue due to significant investments in artificial intelligence and other R&D projects.
Additionally, Tesla earned less from regulatory credits, and average sales prices of its EVs were also down.
