On August 21, 2026, Tesla (TSLA) saw concentrated, high-scale options activity that day: estimated scanned contract premium turnover reached ~$1.517 billion, with total contract volume of 3,608,402, ranking first among 30 scanned symbols that day. The underlying closing price that day was $345.13, with nearest expiration on the same day (August 21, 2026). The largest active contract was the August 21 expiration call option with $360 strike, TSLA260821C00360000, with ~$134 million in premium turnover. The ATM straddle implied price move was 5.5%, with average near-the-money call IV at 169.0%, average put IV at 245.9%, and a put-call volatility skew of 76.8 percentage points.
Options Flow Snapshot
Detailed metrics include: 2,288,367 call contracts traded, 1,320,035 put contracts traded, for a call-put volume ratio of 1.73; total options premium turnover equaled ~15.0% of the underlying stock's daily dollar volume; 880 contracts were observed in the near-the-money window, with the ATM call strike having 0% IV (likely due to extremely low liquidity) and the ATM put strike having 135.7% IV.
Signal Read-Through
This event represents a market signal of concentrated trading paired with downside volatility skew: on one hand, the single-day options trading volume was significantly above typical levels, with a large call option betting on the underlying price rising above $360; on the other hand, put option implied volatility was notably higher than call option implied volatility, indicating market participants are pricing in greater downside risk.
Fundamental and Event Cross-Check
Cross-referencing public disclosures: Tesla’s Q2 2026 earnings report, released July 22, 2026, showed revenue of $28.236 billion, beating the consensus estimate of $26.423 billion, but EPS of $0.33 missed the $0.50 consensus estimate. On the same August 21, 2026 date, media reports covered Nevada’s approval of Tesla’s 5,000 fully autonomous vehicle fleet and news related to Tesla’s solar roof business. As of December 31, 2025, Tesla had 4,555 institutional holders, holding 49.6% of the float, with 530 new institutional positions added in Q2 2026. Additionally, CEO Elon Musk and CFO Vaibhav Taneja executed insider stock trades in June and May–June 2026, per Form 4 filings.
Follow-Up Markers
This signal only reflects August 21, 2026 options market pricing and trading activity, and does not directly prove future directional stock price movement. Key items to monitor include: 1) subsequent position changes and exercise status of the large $360 strike call option; 2) whether Tesla’s subsequent stock price volatility matches the 5.5% implied move; 3) latest business updates from official SEC filings or company public disclosures.
