Past Tense of “outbid”
The past tense of outbid is outbid; the past participle is outbid.
Why “outbid” behaves this way
"Outbid" is built from the prefix "out-" (meaning "to surpass" or "beyond") bolted onto "bid," and it simply inherits bid's own irregular pattern rather than developing one of its own. "Bid" itself has been a zero-change verb since Old English — its past tense "bead" and its modern "bid" collapsed into the same shape as the language's vowel system shifted over centuries, leaving one of the small set of English verbs that never change form for the simple past. Because "out-" is a purely productive prefix that English speakers can still attach to almost any verb (outrun, outshine, outsmart), "outbid" didn't need its own irregular history to develop — it just rides on bid's existing irregularity, a pattern true of every "out-" compound on this page. Auction-house terminology has used "outbid" as its standard technical verb for centuries, distinct from the more general "bid against," since "outbid" specifically implies a successful, higher offer rather than merely a competing one.
This is worth flagging because learners sometimes assume a compound verb must have its own separate irregular past form, when in most "out-" verbs in English the prefix is transparent and the base verb supplies 100% of the irregularity. Compare "outdo," which inherits do/did/done wholesale; "outbid" inherits bid/bid/bid the same way. The only place "outbid" diverges from ordinary "bid" is meaning: "bid" just means to offer a price, while "outbid" specifically means to offer a higher price than a rival, a competitive sense the prefix adds on top.
The common confusion
The confusion isn't over which form to use — "outbid" never changes — it's that writers instinctively want to add "-ded" ("outbidded") by analogy with regular verbs, since a two-syllable compound feels less obviously irregular than the short monosyllable "bid" does on its own. There is no such form in standard English; the past tense and past participle are both simply "outbid," identical to the present.
How it's actually used
"Outbid" appears almost exclusively in auction, real-estate, and competitive-bidding contexts ("she was outbid at the last second"), rarely in a generalized figurative sense the way some "out-" verbs (like "outshine") have drifted into everyday metaphor. Context alone usually tells you the tense, since "outbid" needs a helping verb ("has outbid," "was outbid") or a time marker to distinguish past from present in writing. Real-estate journalism, especially coverage of hot housing markets, uses the passive "was outbid" constantly to describe buyers losing out on a property, almost always paired with a number ("outbid by twenty thousand dollars") that quantifies the margin of loss.
Across the tense system
Present and past look identical ("they outbid every rival this year" could describe either an ongoing habit or a single completed act), so this verb leans especially hard on auxiliaries to clarify tense: "is outbidding" for the present progressive, "had outbid" for the past perfect, "will have outbid" for the future perfect. Auction reporting typically narrates in the simple past for the winning bid itself ("she outbid the room") but switches to the present perfect when summarizing a broader pattern across a whole sale ("she has outbid every rival collector this season"), a stylistic choice rather than a grammatical requirement.
Common real mistakes
The single recurring error is adding "-ed" ("outbidded") in past-tense writing, especially from writers who know "bid" is short and simple but forget the compound inherits the same irregularity. A second, smaller error is treating "outbid" as needing "on" ("outbid on the house") rather than the correct direct-object construction ("outbid them for the house" or simply "outbid them"). Because auction and real-estate writing both favor short, punchy sentences, the "outbidded" error tends to show up more in headlines and captions than in longer-form prose, where writers have more time to catch the mistake before publishing.
Examples
- She outbid three other buyers to win the auction.
- By the final round, no one could outbid the collector.
- They have outbid every competitor at this year's sale.
- He was outbid at the last second by an anonymous phone bidder.
Memory trick
Think of "bid" as a word too short to bother changing shape — like "hit" or "cut" — and remember "outbid" just carries that same shortness forward: bid, bid, bid; outbid, outbid, outbid.
